Geological Engineering Study Program, Hasanuddin University, Geology Engineering Building, Engineering Faculty, Gowa Campus Jl. Poros Malino, Gowa, South Sulawesi, Indonesia. safruddimahmad[at]yahoo.co.id


Abstract

Natural disaster risk is considered in regional planning in order to reduce risk potency. Parepare is one of the district in South Sulawesi which has natural disaster potency such as flood, landslide and hurricane. Parepare lies in a very strategic area which is connecting the northern and southern parts of South Sulawesi. As a strategic area, Parepare grows rapidly and therefore the land conversion from forest and paddy field to settlement also increases. Impact of increasing settlement and other infrastructures are decreasing land capacity and tend to increase disaster potency. The natural disaster study indicates 3 major potencies arising: flooding which dominantly occurs in Karajae River, landslide which commonly took place in hilly topography and hurricane everywhere in the city. To handle this condition at least 3 step should be applied: a) prevention that includes all efforts of disappearing in reducing disaster; b) mitigation covered reducing disaster impact and c) preparedness activity for anticipating disaster.

Keywords: City of Parepare, disaster, vulnerability, land capacity.

Abstract

Olistostrome is clastic sedimentary rock, its formation related to tectonic activity along the plate subduction edge on the front region of the accretion prism. Its formation is a submarine landslide with a mud flow sediment mass. The material components can be mixed from various continental and oceanic sources.
As in the complex area of Bantimala tectonics, olistostrome shows typical properties of ugly sorting, floating rock blocks in the sandy matrix, tectonite textures, constituent rocks generally in the form of metamorphic rocks of subdusion and plate collision. The criterion shows the submarine sludge deposits formed in the subduction tectonic area of the marine trough environment where there is an increase in slope due to subduction accretion.
This study aims to examine the characteristics of olistostrome as a landslide deposit in the subduction zone in relation to the correlation of disaster in convergent tectonic areas in the present.
In the area of Bantimala the exposure of olistostrome rock are large enough with large dimensions with a megalandslide. This can happen by earthquakes or critical slope in the past. This phenomenon can be a reference to disaster present-day in subduction areas, as in the island arc of Indonesia, which is a collision area of three large plates, very vulnerable to this disaster.
Submarine landslide can cause disaster to infrastructure, telecommunication cable, gas hydrate dissolution, tsunami disaster and environmental destruction of marine benthos

Abstract

The Rumbia Complex is located in the Southern part of the Southeast Arm of Sulawesi is one of the regional Metamorphic Complexes in the Sulawesi Island. Based on the results of 40Ar/39Ar radiometric age dating of three metamorphic rock units from this area, it is shows the age spectrum reflecting that there have been three major geologic events at the Rumbia Complex during the Miocene. This great geological event is interpreted as a result of amalgamation between the microplates of Rumbia, Mekongga, and Meluhu, forming the Southeast Arm of Sulawesi, as we known today. It appears that this great popular geological event referred to as this catastrophic, is responsible for the abundance of Nickel Laterite ore deposits, and other sulfide ore minerals in the Southeast Arm of Sulawesi.

Hasanuddin University


Abstract

The increasing number of tourists visiting in small islands has directly affected the development of low-income settlements spontaneously to support the tourists accommodation, but the development itself has, at the same time, ignored the humanistic environment. Several of cities in Indonesias belong to the high risk index of disasters, including Samalona Island of Makassar City. Therefore, the planning components to resolving disasters on tourism settlements in small islands are needed as follows: 1) identifying the role of elements in the natural mitigation and in the artificially structural mitigation that is available, and the role of local residents to overcome disasters in the coastline of small islands, 2) analyzing the condition of abrasion disasters like storms, gale, and flood tides towards the houses, gazebos, and stalls in small islands. In order to achieve the purpose, The data come from the observations, sketches, and direct interviews with the local people owning the houses, gazebos, or stalls. The analysis with sustainable approaches is to reach the development of small island destinations that are safe, comfortable, environmentally friendly, and able to increase the incomes of the local residents. The research results describe several mitigation elements in small islands such as the local vegetation with tree trunk diameter is 1.5-2.0m, the branching system covers 80% of the island area. The coastal areas have no more natural mitigation elements to block gales, wave pressures, and tides. However, the roles of society can be seen in the existence of structural mitigation elemnets such as locally wooden breakest water conventionally made. The condition of abrasion disasters and gales can be found by the changes of beach sand shape not parallel with the seasons, the site of houses, gazebos, and stalls that are always moved in safe locations temporarily. The planning components to resolving disasters in tourism settlements of small islands are landscape recoveries (vegetation replanting) on disaster-prone locations (gales and abrasions) for the settlements in coastlines, building the sea embankment that has double functions (breakwaters and pedestrian ways), and displacing the houses that are suitable with wind intensity and building height (landed houses or elevated houses).

Abstract

Referring to International Panel on Climate Change (IPCC) Report, the global warming will affect on the sea level rise over the world. This phenomenon will be a serious issue particularly for coastal city such as Makassar. This research aims to predict the inundation areas along the coastal of the city due to sea level rise, and its impact on the number of building units which will be drowned by inundation. The focus of the research was on the coastal area of Makassar city; it covers 25 neighborhoods which have 4,647.1649 ha area and sited by 32.929 building units Data of neighborhoods administrative area were collected from the RTRW Makassar, while the building units in each neighborhood were gained from digitized map downloaded from Google Earth. Based on the DEM ALOS PALSAR and by applying GIS, the inundation area and the number of buildings could be predicted. In a scenario of 25 cm rise from the current tidal level, the predicted inundation will be 1,290.0025 ha (= 27.75%) and the amount of threatened buildings will be 1,153 units. In terms of 50 cm and 75 cm rise, the total inundation areas and the amount of threatened buildings show the similarity with the rise of 25 cm. On the other hand 100 cm rise predicts the inundation area will be 30.7468 ha and the total number of threatened buildings will be 1,645 units. As conclusions, coastlines are the vulnerable area and it is recommended that to avoid flood and inundation, the ground floor of buildings should be higher the inundation level.

Abstract

South Sulawesi is one of the provinces in Indonesia with highest economic growth index. This situation gives an impact to the intensive infrastructure development including road access, bridge, dam, airport, seaport and other public facilities in the province. However, due to geological complexity of the region, the infrastructures developments are threatened by natural hazard especially earthquake, landslide, tsunami and flooding. The occurrences of these natural hazards are regionally controlled by geological condition including geomorphology, stratigraphy and structure geology. Therefore, in order to mitigate these natural hazards, geological consideration should be taken into account in natural hazard mitigation scheme. This study outlines the model for natural hazard mitigation in South Sulawesi using geological consideration of the region.

Abstract

Plastic optical fiber (POF) used as sensors to detect cracks in concrete structures. Sensors made using straight, sinusoidal, loop, and triangle configurations. The POF connected to LED light source and photodetector. The light from LED will propagate along the embedded POF in the concrete then received by the photodetector and measured using by Optical Power Meter in the form of output power displayed on the computer. Sensor testing done by putting pressure on the concrete using the Ultimate Testing Machine until a crack occurs causing the POF in the concrete to experience strain. The strain of the POF sensor will cause power losses, so the light intensity received by the photodetector will be decreases. The best measurements obtained at triangle configuration sensors 60&#8304; have characteristics with a range value of 1,975 &#956;W, sensitivity of 0,790 &#956;W/mm and resolution of 0,001 mm. Sensors based POF for measurement of cracks in concrete structures have the advantages like easy fabrication, low cost, simple measurement system, and high sensitivity.

Abstract

Due to its geographical location, Indonesia is very vulnerable to the volcano eruption. Volcanic eruptions always bring impact to the surrounding community. According to Indonesian National Board for Disaster Management or Badan National Penanggungan Bencana (2016, www.bnpb.go.id), the volcano erupts as a result of volcanic activity (eruption). Erupting volcanoes can pose many hazards. The eruption expelled hot lava, bursts of material (incandescent), volcanic ash, poisonous gases, etc from volcanic vent. In addition to causing a lot of casualties, the eruption some times caused tsunamies, also caused huge economic losses due to the number of damaged infrastructure and the need for high recovery costs. To mitigate the negative impact, especially the impact on the safety of the population, a disaster management is required. One of the concerns of disaster management is a proper allocation and scheduling of rescue teams in order to minimize evacuation time with expectations of saving as many lives as possible. For that purpose, RUASP (Rescue Unit Assignment and Scheduling Problem) optimization model by Rizqi (2016) is used as the initial model. This model has an objective to minimize a completion time of evacuation. This model considering many important factors, such as factors of severity of damages and capability of the rescue team. Though, there is still few crucial factors that have not been considered in this model. It is not yet considered a period for rescue teams to be able to perform their duties safely nor fuzzy time on the fields. Physical limitations and device limitations are the inhibiting factors for evacuation activities during low light conditions. However, this model has not considered a safe period for rescue teams while on duty. Therefore, we proposed a development model that considers safety time, by adding time window as a constraint and some adjustments to GRASP Metaheuristics steps.
To achieve the objectives of this research, systematic and structured steps are required in order not to deviate from the path. The first step is to identify the problem. The second step is to do the necessary literature study. The third step is defining the formulation and the purpose of the problem to be achieved. The fourth step is to set up a scenario that consists of some data obtained in the field (such as the location of the incident) and some assumption data (such as operational time). The fuzzy data is collected from the town surrounding mount Semeru. The data obtained in the field is related to the number of location of the incident as many as 17 locations and the location of the post that is located in Kota Lumajang. The fifth step is to arrange MATLAB programming for the initial method of GRASP Metaheuristics. To test the model we use a certain historical data. The completion time of new model is 21.92% faster than the initial model with computation time of 12.56 seconds.

Department of Industrial Engineering, Faculty of Engineering, University of Surabaya


Abstract

The volcanic eruption disaster always gives an impact on the community around the disaster location. Rapid responses, as well as prompt and responsive assistance, are needed to reduce the impact and number of victims. During the emergency response period in some cases of our research, there is often a shortage of relief items delivered in some locations, although relief items are available in other locations. This is partly because impact prediction and contingency plans have not been optimal and have not considered the local characteristics that could affect the impact of the eruption. Therefore, a model for humanitarian logistics with local characteristics is needed to predict the impacts and needs of the victims of the volcanic eruption. The model took into account the specific factors in each volcano combined with the flow of goods and the flow of information from all parties involved. This model predicted the radius of impact of eruption based on factors that exist in every mount. This study explored an interrelated prediction model between the impact, the number of victims, and at the last, total number of relief items. The prediction model considered wind direction, seasons when the eruption occurs, shape and steepness of the mountain, the presence and position of the river, population density, and so forth so that the affected area is varied accordingly to the conditions of the eruption. A prediction model testing was conducted with case studies on 2 different volcanoes in East Java Province

Abstract

Indonesia is a country prone to natural disasters that are influenced by natural factors and human factors. Natural disasters that commonly occur in Indonesia are floods, sea tides, landslides, earthquakes, volcanic eruptions, hurricanes, and drought. Among these disasters, floods are the most frequent natural disasters in various parts of Indonesia. Based on BNPB, during 2015 there were 1732 incidence of disasters in Indonesia, 92.67 percent of the disasters are landslides, tornado and flood. During 2017, 979 incidence of flood disaster were occurred in Indonesia where 2.518.578 people were affected by the flood disaster. Considering that flood is a common disaster in Indonesia, people should have flood preparedness. This research was conducted at the estuary of Bone River Gorontalo Province. The Bone River is one of the longest rivers in Gorontalo Province that cross Bone Bolango Regency and Gorontalo City. There are many communities living in river estuaries that belong to densely populated areas, so this research is very important to know perception and adaptation strategy of society to flood disaster. This research was conducted by distributing questionnaires to the community and analyzed quantitatively. The results show that most respondents know that they live in flood prone areas, floods can cause various impacts, and floods can be prevented and minimized. The research result are expected to be useful in decision making process for decreasing flood disaster risk at the estuary of Bone River Gorontalo Province.

Abstract

Unclean cutlery can be contaminated by bacteria. The presence of bacteria in the cutlery can be due to poor seller hygiene behavior as well as the application of unsanitary feeding sanitation. This study aims to determine the description of hygiene and sanitation with bacterial contamination on the cutlery in elementary School in Barrang Lompo, Makassar. The type of this research is descriptive research. The sample consists of two components, namely respondent and food samples. Respondent data were obtained by using questionnaires and observation sheet. The food samples were taken using the swab method (rubbing the cutlery surface) and then taken to the microbiology laboratory for testing of bacterial biochemistry. A total of 5 respondents and 15 pieces of cutlery. From biochemical identification, 7 bacteria were found from 15 samples. Gram positive bacteria amounted to 46.7% and gram negative amount of 53.3%. The types of bacteria identified from the cutlery consist of; Bacillus sp., Enterobacter hafniae, Enterobacter cloacea, Enterobacter aerogenes, Acinobacter calcoaceticus, Alcaligenes faecalis and Klebsiella sp. The conclusions of this study are all samples of food tested containing bacteria due to personal hygiene and sanitation of eating utensils that are less good so that trigger the onset of bacteria. The quality of washing water, washing methods and the completeness of sanitary tools such as shelves of cutlery should be the concern of traders to create good sanitation of cutlery so that cutlery can be spared from bacterial contamination.

Faculty Of Law De La Salle catholic University Manado North Sulawesi-Indonesia.


Abstract

The purpose of this research is to study government responsibility in protecting the people from the impact of disaster in guarantee of fulfilling human rights to every person to live and secure performing his/her activity.
The method of research is legal normative. The analysis on the primary and secondary legal materials are conducted comparatively and systematically and the result are explained descriptively and systematically.
The result of the research indicates that the urgency of establishing legislation regulations in the settlement of disaster is focused on the disaster settlement such as; emergency action, rehabilitation, reconstruction in case there is natural, unnatural and social disaster in order to provide legal certainty and justice to the victims of disaster.
Law enforcement is necessary to impose measures on the parties in abusing peoples confidence to help me victims of natural, unnatural and social disaster. Other problem that arouse in the settlement of disaster is that there is no effective coordination among the concerned government instances, resulting in the emergence of problems at the field concerning the competence of the instances, where as preparation in encountering disaster needs good planning so that the performance will be running well.
As conclusion, government responsibility in the settlement of disaster, observed from the aspect of human rights, is performed through determination of development policy potential for the emergence of disaster, activity of disaster prevention, emergency action, and rehabilitation to prevent matters that may threatening and disturbing the life and the living as fulfillment of the rights to live freely from fear and anxiety as result of disaster threat, cause by natural factor, unnatural factor as well as human beings resulting in the death of human life, environmental damages, loss possession and psychological impact.

Abstract

Abstract
Research aims is to develop a theoretical model that explains the role of Burnout mediation in the relationship between Burnout determinants from the emotional aspect, including POF and emotional resources, and consequent affective commitment.
This research is a quantitative research with survey data collection method with questionnaire instrument, and descriptive data analysis method with inferential method includes ANOVA method and structural equation modeling. Data collection on the first eight health services, namely Puskesmas Nuha, Wawondula Public Health Center, Puskesmas, Wasuponda, Malili Health Center, Wotu Health Center, FKTP Vale Sorowako, FKTP Vale Wawondula, FKTP Vale Wasuponda and two hospitals located in Luwu Timur Regency, Inco Sorowako and I Lagaligo Regional General Hospital with a sample of 156 people.
Findings show Person organization fit (individual fit of nurses with organization) has a significant negative effect on emotional exhausted of nurse and also for affective commitment..
Theoretical implications resulting from this research are Individual-organizational fit theory is a theory that is better able to explain burnout because individual-organizational fit also has a significant effect on emotional exhausted, in contrast to self-efficacy theory that has no impact on emotional exhausted. are only able to register basic human emotions and can not make them as one.
Managers need to direct nurse support in a selective and specific manner. and highlight the nurses fit aspect with the organization to keep them out of burnout. Encourage ones self-efficacy nurse to remain moderate in providing good organizational feedback and support, for self-development resources for nurses,
This study is the first to operationalize the emotional resource variables and emotional desires in the research model and see them directly in relation to Burnout.

Volunteer for Disasters: Roles and Contribution of Voluntary Based Emergency Response Groups in Indonesia
Ihsan Nasir

Emergency Management Program, Auckland University of Technology - New Zealand


Abstract

Disaster might disrupt the functioning of a community when its effects surpass the communitys ability to cope. Although most of the literatures in disaster management denote the fact that disaster victims can be self-reliant, support from outside is still needed when the destruction of physical assets, basic services and livelihoods are beyond the communitys capacity to thrive. One of the sources of support is from the service provided by volunteers that can make such a critical contribution in disaster. Volunteers are often from local surrounding communities, bystanders or even victims helping other victims who usually come in aid in large numbers to contribute flexible types of responses, sometimes with less proper standards of safety. When disaster strikes, these volunteers who initially came to join in the relief work can be very useful support during the immediate response. However, studies exploring the role of groups involved in disaster management in Indonesia are limited. There is little information about their motivations to join the group or the type of actions they perform in disaster. This study is expected to fill this gap by investigating the contribution of volunteer groups in disaster responses with a focus on Indonesia. This study aims to understand the nature of the volunteer groups in Indonesia who specifically providing response service in time of disaster in order to know their exact roles and contribution within the disaster management process.

Abstract

Mitigation of Climate Change can contribute to reducing vulnerability and risk to natural and technological disasters. Increased disasters from climate change, already taking attention many countries to reduce their vulnerability to weather and climatic hazards, such as floods, cyclones, heatwaves and droughts. This paper aim to evaluate the Multi Stakeholder Fora (MSF) on Climate Change in Eastern of Indonesia. MSF in Eastern of Indonesia is established as a learning and collaboration forum to manage the different perspective of all stakeholders in the field of social, economics (business), legal, politics and governance and gathering their common strength to deal with the impact of climate change to contribute in disaster risk reduction. The scale and quality of stakeholder involvement in the elaboration of a climate-resilient development strategy will determine its legitimacy, the feasibility of its financing and the effectiveness of its implementation. This calls for a multi-stakeholder approach that involves public officials, businesses, and individual citizens in the definition of the issues and in the identification of the solutions, and which also empowers them to sustain their own livelihoods and aspirations by acting on their capacities.

Abstract

Small islands that compose the Indonesia maritime continent are prone to marine disasters particularly storm surges. Samalona, an islet in Spermonde Archipelago about 6.8 km offshore of Makassar coastline experiences frequent extreme weather that affects its settlement such as repetitive damage or even total loss of buildings and infrastructures. It is an inhabited 2.4-hectare islet that contains 32 building units comprising houses, tourist lodges, public facilities, and coastal edifices such as wave breakers and boat piers.
This research aims to examine disaster mitigation in islet settlements from the visitor perspective with Samalona Islet in Makassar serves as a case. The objectives are: (i) to identify significant variables of building and landscape features, local contexts, and natural threats based on visitor awareness, and (ii) to recommend a conceptual model for disaster mitigation. Data were collected through field observations and questionnaire surveys with accidentally sampled 34 visitors. Quantitative analysis was undertaken using Spearman correlation technique, supported by qualitative examination using visual and spatial descriptions.
The result shows that the significant variables of building and landscape features are strengthening of the framework constructions of wall, roof, and foundation, also the building location. The significant variable of local contexts is strengthening of economic viability, while the significant variables of natural threats are subsequently abrasion, windstorm, and extreme waves. The most influencing factors of the visitor awareness are frequency and duration of visits. Visitors show awareness that preparedness to anticipate potential disaster is of utmost importance to enable reduction of damage by an actual disaster. This concludes that, according to visitor perspective, disaster mitigation for small island settlements should consider primarily structure of the building, the location, and economic viability of the settlement. A conceptual model is hence proposed based on these significant variables.

Save the World versus Man-Made Disaster: A Cultural Perspective
Fathu Rahman

Faculty of Cultural Sciences, Hasanuddin University


Abstract

This article review examines two sides of disaster that are inherent to be a part of human life. Through the cultural perspectives, disaster can be divided into two main parts, namely natural disasters that are given and other disasters caused by human activities that do not keep this nature well. Well natural guarding is closely related to 1) human behavior, 2) worldview, 3) awareness, and 4) caring. These four aspects can be examined from a cultural perspective which in turn will foster a new awareness for humans as the inhabitants of the earth. Save the World is the motto that persuades humans to safeguard the earth and the environment, while Man-Made Disaster is a human condemnation of another human that creates environmental damage that directly or indirectly leads to disaster.
From two sides of this phenomenon will be discussed in this article reciprocally to see the common thread in which the cultural approach can be a recipient of these two poles. In other words, save the world versus man-made disaster will be discussed from a cultural perspective.

Institute Road of Engineering, Research and Development Agency, The Ministry of Public Works and Public Housing, Indonesia


Abstract

The planning of the bridge construction in Digoel river that connects the western part with the eastern part of Boven Digoel in Papua Province is part of the development program as stipulated in PP No 78 Tahun 2014 about Percepatan Pembangunan Daerah Tertinggal. The land, river, and air transport systems that connect between regions in Boven Digoel are very difficult to reach, other things with extreme weather and climate conditions make the transportation cost in the District is very expensive. One of the efforts made to overcome these problems is the construction of road and bridge infrastructure. To support the implementation of infrastructure development in Boven Digoel, feasibility study of road and bridge planning is required. Feasibility study refers to Pd T-19-2005-B (Studi Kelayakan Proyek Jalan dan Jembatan). A feasibility study was undertaken to analyze in more detail some of the proposed road trace alternatives. Based on the results of the feasibility study, two alternatives of road trails connecting the western part with the eastern part of Boven Digoel of Papua Province. The bridge plans were made across the Digoel river. Bridge construction on alternative road trails connecting Kampung Ampera with Tanah Merah is more effective and efficient to choose. Construction of the bridge at the location is safer than the river scouring hazard. The length of the bridge is made larger than the stretch of the Digoel river. This is due to the Digoel river flow always changing every year. From the results of field measurement analysis, the average speed of the movement of the horizontal river flow direction is (80-180) x10(-4) meters / day so that in the 50-year period, the movement speed of the horizontal river flow path becomes (160 - 3200) meters. Based on Kun Qarshov method, the movement of the river flow for 50 years at the location of the bridge connecting Tanah Merah through Ampera Village is 311.64 meters so that the optimum bridge length at the location is designed 600 meters.

Abstract

The performance of a beam subjected to seismic loading was evaluated in this experimental study on a castellated beam using RBS (reduced beam section) as the damping factor in earthquake-resistant structures. The study used two specimens, one castellated beam with RBS and one without RBS. The specimens were tested in an exterior connection structure model subjected to cyclic loading gradually until collapse. The experiment using cyclic loading was used to evaluate the deformation and the acting force influenced by RBS placement on the column face. The RBS placement on the column face shows that failure occurred on the beam due to elastic deformation. The specimen with RBS had load melting point of 8 kN on 1.05 % drift ratio, 9 kN load on 2.1% drift, 12 kN peak load on 3.20% drift, and load necking phase of 10.53 kN on 4.17% drift. Meanwhile, the specimen without RBS had load melting point of 9 kN on 1.1% drift ratio, 9 kN load on 2.13% drift, the peak load of 12.5 kN on 3.20% drift ratio, and load necking phase of 11 kN on 4.4% drift ratio

Abstract

Sentani Lake is one of the lakes that has a lot of potential in natural resources. This potential such as a source of clean water, for transportation, fisheries, irrigation and for tourism if managed properly can give benefit for the society around the lake. Sentani Lake is located in Jayapura Regency, Papua Province.
This lake is under the slopes of the Cyclops Nature Reserve with range of approximately 245,000 hectares. Sentani Lake is located in the southern city of Sentani which is the capital of Jayapura Regency. This area reaches 9360 ha with a storage capacity estimated at 2,716 m3. Sentani Lake receives water from 14 large and small rivers that culminate in the mountain Cyclops and then draining to the Pacific Ocean and flowing out through Jaifuri River. Total area for watersheds about 517 km2 with an average rainfall of 1.691mm per year, so the availability of water in a year reaches 404m3 / sec. Sentani Lake is a lake with hilly islands in the middle of the lake and it has a height of 70 - 90m above sea level.
On the other hand the existing site of Sentani Lake has started to experience ecological threats due to environmental degradation. Various problems that arise include flooding, erosion and high environmental pollution due to domestic waste, livestock and industry that all flow into Sentani Lake.
Based on land slope map, Sentani Lake area has a moderate slope of 17-52% that allows sedimentation because of erosion process in the region. This can lead to flooding due to sediment build up and rising waters of Sentani Lake. This situation needs an integrated handling from upstream to downstream so that the environmental impact of flooding can be minimized. Sentani Lake can be maintained by improving aspects of hydrology, land use aspects, as well as improvements in environmental aspects such as spatial arrangement in accordance with the carrying capacity.
This article will focus on studying the prevention of natural disaster such as flood, erosion and environmental pollution. This study will also try to analyze factors that caused the degradation of Sentani Lake. Moreover, the actions plans that need to be conducted to maintain Sentani Lake will be analyzed such as revitalization in hydrology aspect, land use, and land planning base on carrying capacity of Sentani Lake.

Abstract

The incomplete roads are designed only for cars, with limited transportation options make pedestrians, pedestrian, and other transport users feel uncomfortable and safe and risk dangerous. Bicycle as a more environmentally friendly means of transportation which is an alternative mode of transportation that can replace motor vehicles in an effort to reduce the impact of global warming. The facilities for bicycle users provide a sense of security and comfort for various users and is considered an important part of complete street where if a society of 100,000 people replaces their entire car by cycling once a month, it will reduce the carbon dioxide gas (C02) by 3.764 tons per year. Yos Sudarso Road in Mamuju City is a road segment with activities in various zones, the intensity of activities that occur on the road is very high at certain hours, due to the different activities of the diversity of building functions. Road conditions that do not provide facilities for bicycle users require assessment of the needs of bicycle lane and analyze how the design of the concept of bicycle lane on the road segment is based on the complete street concept. The type of research used is non-experimental descriptive with qualitative and quantitative approach, using survey method in the form of direct observation at research sites, interviews and questionnaires. The condition of the road lane is not yet based on the complete street concept because there is no bicycle lane available as one of the complete street elements so it does not provide a sense of security and comfort for bicycle users. The need for bicycle lanes based on the responses of respondents is that they need to provide bicycle lanes on segment 1 with bike lane type, in segment 2 and segment 3 with bike lane type, for provision of bicycle lanes based on bicycle volume and volume cross bicycle lane needs of Yos Sudarso road segment is not yet necessary to be provided. The recommended implementation of bicycle lane based on the Complete Street Concept is a bicycle lane (width of 1.5 meters for a one-way lane with elevated surfaces that can still be passed by motor vehicles in an emergency condition. A safe and comfortable bicycle lane improves peoples enthusiasm using bicycles as a mode of transportation that can help reduce carbon dioxide (C02) gas and improve clean air quality.

Iqbal, Mahmud Achmad, and Muhammad Tahir Sapsal

Engineering Agricultural Program study, Agriculture Faculty, Hasanuddin University Makassar


Abstract

Intensive agricultural land use tends to reduce the content of organic matter in soil. Organic content in the soil affects the soils ability to bind water and the efficiency of fertilizer absorption by plants as well as an important source of nutrients for plants. Therefore, the addition of organic matter in the form of compost is very important for maintaining the productivity of agricultural land. Problems that occur at the time of application of compost is needed manpower and considerable expense, so it needs an efficient technology in the form of mechanical equipment that is simple and easy to operate. The purpose of this research is to design an organic fertilizer applicator for paddy that can be operated on rice fields. Applicators have been made and functioning well and able to apply organic fertilizer with a dose of 15 tons/ha.

Civil Engineering Department, Engineering Faculty, Hasanuddin University


Abstract

Trestle is a connecting bridge between the mainland and jetty, located in tidal areas with a high risk of corrosion and concrete deterioration. Generally, trestle structure construct for reinforced concrete and steel structure, which are particularly vulnerable to damage due to corrosive environment. As one of the major port support facilities to accelerate economic growth and distribution for industrial and agricultural products, it is necessary to have regular evaluation and maintenance.
Biringkassi port which belongs to PT. Semen Tonasa has been operating since 1988, and it is continuously adding facilities to support the cement distribution by sea. This study aims to assess the level of concrete deterioration and evaluate the capacity of trestle structures, which heavy vehicles pass at all times.
Results of concrete quality evaluation with ultrasonic pulse velocity and core drill concrete showed satisfactory results with the average quality of concrete over the 30 N/mm2. However, from the structural capacity review to the service load, it is necessary to limit the maximum load and repair the existing concrete deterioration.

Abstract

One alternative in the modelization of steel structural elements is the castella steel beam. This study aims to determine the strength and stability of the normal castella beam due to static loading, cyclic loading and know the damage model of the two types of loading. In this research used normal steel beam IWF 200.100.8.5,5; normal profile steel beams modified into castella steel beams and composite castella steel beams, with hexagonal opening forms, 0.6H aperture height, 9 cm opening distance and 600 opening angle. The results of this study indicate that the moment capacity of composite castella beam with cyclic loading increased 475% from castella beam with static loads. While the load capacity on castella beam with static load increased 152% from composite castella beam with cyclic load. The deflection occurring in the composite castella beam with cyclic loading increased 399% from castella beam with static load. The collapse mechanism of the castella beam with static load is the lateral-tortional buckling and web-buckling. While the collapse mechanism on the composite castella beam with cyclic load is cracked on the concrete stuffing. This shows that the model of composite castella beam can be applied to structures built on earthquake-prone areas.

Abstract

This research goal is to find characteristic of construction stilt house tiang jangkung dan bengkok (tall and bent poled) of Kampung Toa Bikombang. Knowledge regarding tall and bent poled stilt house was developed and understood by traditional community of Kampung Toa Bikombang and was inherited from generation to generation. Kampung Toa Bikombang in Selayar Island is an old village with its own unique architecture. Their stilt house was built on rocky slopes with steep height level difference between 5-10 metres. The shape of its pole is not straight. With their inherited knowledge from previous generations, Bikombang residents are able to build long-lasting houses, even last for hundreds of years. The fact that the houses was able to withstand years of various extreme climate and weather conditions shows that Kampung Toa Bikombang residents have some knowledge regarding structure and construction system of stilt house buildings.

This research uses Qualitative Research Method mentioned by Bogdan and Taylor in Moleong (1994). They described qualitative method as research procedure to produce descriptive data in written and verbal words from people. The research theoretic foundation is based on explorative approach with naturalistic paradigm. Field observation become the main focus in data collection regarding shape, structure and construction system of Kampung Toa Bikombang houses.

The research result shows the characteristic of Kampung Toa Bikombang tall and bent poled stilt housed. In structure system, pole was placed standing up on top of rocks sustained by pedestals (not planted in the ground), the length of pole adjusted with the contour of rocks and mostly rear part of the house is higher than then front part. Poled is placed standing in its intact form and every pole bent. Stage house was built by using a pole construction that is not straight and the placement of a pole bent with another pole with the opposite pattern, to provide stability in the construction

The result of this research is expected to preserve the knowledge of traditional society which has been inherited and passed down from generation to generation. We also hope it will help to expand and grow the knowledge from the tradional society especially for South Sulawesi architecture as an effort to preserve culture and architecture.

Abstract

The rapid growth of the global economy in this last decade requires the improvement of operational management efficiency of container terminals, to response the 4% growth of container shipping demand in international trade, with world container port throughput reached 701 million TEUs in 2016 (UNCTAD, 2017). Various efforts have been made by container terminal managers to increase the productivity level of limited resources. The main resources at container terminals are the availability of quay seaside and container storage yard on the land-side. The maximum of berth utilization is influenced by the allocation of vessels into berth segments and the number of quay cranes assigned to serve the discharging and loading activities of containers into each arrived vessel in container terminal. Tactical decisions in the Berth Allocation Problem and Quay Crane Assignment Problems in resource management in seaside of container terminal are intertwined with each other, such that needs to be taken into account in an integrated manner. In addition, container terminal managers often face the uncertainty of ship arrival time and the number of containers that must be discharged and loaded into each arrived vessels are in uncertainty environment, such that needs to estimate the handling time required. This results in container terminal managers having difficulty in providing services that ensure the shipping liner owners satisfaction.
Therefore, this paper discusses the robust optimization model development to integrate tactical decisions on seaside operations in container terminal, that is consist of Tactical Berth Allocation Problem and Specific Quay Crane Assignment Problem by considering the uncertainty of vessel arrival time and the number of containers to be discharged and loaded into the arrived vessels, which also affects the uncertainty of handling time required. The development of optimization model considers container terminal managers and shipping liner owners viewpoints. Thus this optimization model has two objective functions, i.e. minimizing total costs of seaside operations and maximizing service levels for shipping liners. Since these two tactical decisions for seaside operations are inter-related each other, the robust optimization model is solved by using the Functional Integration Approach with Feedback Loop Structure, which is applied to a numerical example for testing the effectiveness of the proposed method.

Abstract

ABSTRACT
The transportation service of the land, sea and air transportation of Papua Province is still very low, due to geographical, topographic, soil conditions and social constraints that hamper infrastructure development. The development of the road network is only focused on meeting the accessibility needs of the production centers to the distribution centers. The phenomenon of inequality that occurs in the world and the territory of Indonesia, also occurs in the province of Papua. The gap between regions can be seen primarily by the lagging regions of the Central Highlands of Papua with other regions, especially with the coast of the North Coast of Papua. Identified there are still 14 (fourteen) isolated points / areas, where the development has not touched at all. In addition there are still border areas and small islands and outermost NKRI conditions are still very left behind. (Regional Development Planning Board of Papua Province, 2007). Many obstacles faced in the implementation of road pavement projects in Papua Constraints encountered, among others, very difficult geographical conditions, unpredictable weather, material, and In addition, security problems and customary rights issues in Papua are also a constraint on the implementation of infrastructure development roads in Papua that have an impact on cost performance. Data collection was conducted on 45 construction service companies in Papua. The data used are primary data and secondary data. Primary data based on questionnaires and interviews, while secondary data based on data collected from various agencies, both government agencies and private agencies, namely Public Works, Central Bureau of Statistics, and others. From the results of this study there are five issues that are most considered to be the biggest risk that affect the time is the risk of uncertain weather, material damage to the project due to the transportation process, the dismantling of storage & the low quality of materials, the lack of expertise, the risk of political and social stability on site.The study in this research is an analysis of risk assessment on time performance on road infrastructure development in Papua.

Abstract

One indicator of the decline in watershed performance is the increase in the ratio of maximum discharge to minimal discharge due to large surface runoff when rain occurs. Land use for cocoa cultivation can increase surface runoff by 389% compared to forest land. For this reason, it is necessary to implement a zero run-off system technology that can minimize surface runoff through increasing groundwater recharge. Groundwater recharge in the Zero runoff system was determined using Darcys approach. This approach requires hydraulic gradient data obtained through measurements of groundwater levels around the ZRO system using two monitoring wells and hydraulic conductivity data of saturated soil. Groundwater levels are measured interactively using a sensor level liquid aqua plumb with vegetronix data logger recording. The saturated hydraulic conductivity was determined using the falling head approach. Based on the result of the research, hydraulic gradient in one of the ZRO system in the research location is 0.4 and the saturated hydraulic conductivity of 2.61 x 10-5 m/s shows that the soil in the research location is textured moderate coarse or loamy. Thus, the velocity of water entering the soil is 1.04x10-5 m/s so that discharge of the groundwater recharge for one ZRO system is 4.16x10-5 m3/s with the cross-sectional area of the system ZRO of 4 m2.

Abstract

Climate variability in a region leads to the increasing rainfall intensity during the rainy season and the increasing number of days of dry season. This condition is happening in most part of Indonesia, especially in the South Sulawesi province where it has a quite complex characteristic of the ecosystem. One of them is Bantimurung-Bulusaraung National Park with a special characteristic of landscape in the form of karst area and the people in the buffer villages located in Maros, Pangkajene Kepulauan and Bone Regions depend their livelihoods in the park. One of the impact of climate changes happening around the National Park area is the increasing potential of flood. The flood mostly occurs due to the high rainfall in the rainy season supported by the characteristics of land in the form of karst area that very quickly passes the water. Flood hazard analysis in Bantimurung-Bulusaraung National Park area was assessed by using Soil and Water Assessment Tools (SWAT) model on actual condition (climate period 2004-2013) and projection of climate change in 2030s using scenario RCP 4.5 (rainfall scenario tend to decrease) and RCP 6.0 (rainfall scenario tend to increase). Based on the SWAT model analysis results, it is known that there are areas of the buffer villages of Bantimurung-Bulusaraung National Park, which has a very high level of flood, which the actual condition of the affected area is 10,380.31 ha and on climate change projection of scenario RCP 4.5 covering 9,061.99 ha and RCP 6.0 scenario covering 24,188.26 ha.

Abstract

Tree root systems can reduce landslide risk and stabilize river banks. As part of a broad evaluation of the role of agroforestry in maintaining watershed services and reducing natural hazards in the humid tropics, case studies in two catchments in Indonesia included individual root, rooted soil volume and tree-root-system level effects. The major part (81%) of variation in root tensile (breaking) strength at standard root diameter across 5 species was accounted for by the model: Lignin content plus 0.76 times Nitrogen minus 0.07 times Polyphenol content. Tree root length density (Lrv) was weakly correlated with soil shear strength (SS), but it improved a mixed model with soil texture parameters. Overall, bamboo plots had the largest soil shear strength and the highest root length density. An index of root anchoring (IRA: ratio of cross sectional area of vertical roots and stem) was assessed across 25 tree species (5 year old) in agroforestry system; the highest IRA (7.7) was observed in non-pruned coffee, while pruning stimulates formation of roots in the surface layer. Three other tree species (Artocarpus elasticus, Parkia speciosa and Durio zibethinus) had a high IRA value (>1.0), and tend to grow to larger dbh values, providing more anchoring than coffee on a per tree basis. The common shade trees in coffee agroforestry system i.e. Gliricidia sepium and Erythina subumbrans and the tree most frequently used for government reforestation programs in the past, Calliandra calothyrsus, have low IRA values, indicating little soil anchoring; other timber and fruit trees had intermediate IRA values. Based on these data, a mix of tree species with different pattern of rooting characteristics grown to mature size will provide a good protection of the soil surface and also increase river bank and hill slope stability.

Abstract

FAMILY AND ORGANIZATION ROLES IN NON NATURAL DISASTER RISK REDUCTION: BURNOUT REDUCTION ON WORKERS
Research and theories on the role of families and organizations in reducing disaster risk is still limited to home and corporate efforts on the aspects of natural disasters risks. Non-natural disasters such as techological failure, modernization failure, epidemics, and disease outbreaks are still rarely addressed by families and organizations. This non-natural disaster can be caused by the failure of the workforce in the industry and health personnel in the health care institution in implementing safe and careful work procedures. In turn, this can be caused by burnout, a psychological problem in the worker or health worker. This paper develops a conceptual framework to describe what steps can be taken by families and organizations in reducing burnout to workers and health workers. The concepts of leadership, organizational culture, role expectations, and work-family conflicts are introduced to explain burnout factors that families and organizations can manage in the context of non-natural disaster risk reduction.

Abstract




Abstract
This paper investigates specific risk in emerging market. Emerging markets are accumulating capital at a faster rate than developed markets but they lag far behind developed markets. Risk is one of the main factors that investors consider when making investments.
Risk contained in Financial Accounting come from accrual accounting method. Accrual measurements in the Balance Sheet are measured using persistence current operating accrual, persistence non-current operating accrual, persistence financial accrual and accrual anomaly. Accruals in income statement are measured using the accrual anomaly modified jones model. Accrual measurements are used as information used by investors in predicting risk specific. The idiosyncratic risk reflects the specific information about the company and it will fluctuate according to the information itself.
To measure the risk in this study five factors of Fama-French were used. Using the SEM AMOS Ver.24 and Sobel Test Path Analysis, we find that the financial risk documented in this study is associated to risk faced by investor. Prospect Theory can be used to predict and explain behaviour decision making to overcome disaster risk faced by investor in the future.

Abstract

The selection of community transport mode is the result of transactions between supply and demand activities and depends on the position of each mode associated with its competitors. In Indonesia, the selection of metropolitan community modes is not based on the function of socio-economic characteristics of a person, movement system, and level of service mode. The model of the current mode selection function is based only on the approximate choice of modes, regardless of how the process of selecting the modes in real terms.
This study intends to complement the mode of transportation mode selection function in Mamminasa Metropolitan. Specifically do with two objective, first, to examine the model function of transportation mode selection based on socio-economic characteristics of community, movement network and transportation mode services; second, to examine the relationship between the variables forming the function of the utility choice and the validity level of the chosen function model through the detailed searching of the explanatory variables of the mode of transportation selection, based on the perception of the communitys wishes and explaining the probability of individuals in choosing the mode of transportation.
Data collection options in Mamminasata metropolitan main corridor movement, due to the uniqueness of activity between regions, the volume of traffic community is relatively high compared to other regions. Given the complexity of coverage, this paper is restricted to the motorized transport modes with the type of movement of the home base trip. Application of Multinomial Logistic Regression method was used to examine variables are influential in the choice of transportation mode selection through a proportionate stratified random sampling of primary data questionnaire.
The implications of this research are mainly in strengthening the function of a more complete mode selection system that describes the process of selecting, demanding and transport mode capabilities, contributing to the development of transportation planning and modeling. While the benefits are expected as a tool of policy interventions in handling transportation issues metropolitan in Indonesia.

Faculty of social and political sciences, Hasanuddin university


Abstract

Indonesia is an archipelago-shaped maritime country, having a territorial sea area of 3,288,683 km2 with a coastline length of 95,161 km. lies along the equator, between the continents of Asia and Australia. Residents living in coastal areas form a community known as the maritime community. In South Sulawesi, especially the west and east coasts, maritime communities occupy areas that are geographically vulnerable to disasters. An actual empirical maritime community in South Sulawesi, able to survive because it successfully developed an adaptive mechanism in overcoming various disasters that occur. The adaptive capacity possessed is summed up in a potential called local wisdom, which includes a belief system, a knowledge system and a value system and a habitual pattern that is continuously inherited from generation to generation. In the perspective of theory, disasters that occur in a society are divided into two types, namely natural disasters caused by natural events such as earthquakes, landslides, winds and others, and social disasters caused by human behavior. The focus of this research is to explain how the characteristics of disaster happened to the maritime community, and how socio-cultural potentials are owned by the community as a coping strategy, how to apply local wisdom as a disaster mitigation effort, and how to understand and handle the disaster. The description of the problem provides a complete picture of how the sociocultural strategies used by maritime communities in the coastal areas cope with the disaster that afflicts them to survive and exist.
This research is ethnographic with the qualitative approach, conducted in Barru Regency, South Sulawesi. Data collection through in-depth interviews, participant observation, and literature review.
The study finds that maritime communities in Barru District are familiar with a number of disaster characteristics such as whirlwinds, seasonal disasters, fire disasters, and floods. They overcame these natural disasters by exploiting their local wisdom in the form of belief systems, knowledge systems, and customs to exert wind power so that the scale of damage is smaller. Similarly, the fire disaster is overcome by reading certain verses in the Quran while being observed near the burning fire, believed to be able to reduce the anger of fire. Flood disaster is overcome with various treatments directed to the water ruler and the ruler of the river in the form of ritual. This study concludes that the socio-cultural potential in the form of local wisdom possessed by the maritime community is an adaptive mechanism for overcoming and mitigating disasters.

Based on the results of data analysis that has been done, it can be concluded that Corporate Social Responsibility does not affect the financial performance proxied in Return On Assets (ROA), this is because the size of the companys ROA will not affect the disclosure of social responsibility by the company. Companies that have large assets do not necessarily pay attention to or show good performance through their concern for the social environment. Corporate Social Responsibility affects the financial performance proxied by Return On Equity (ROE), this means that the higher the CSR disclosure, the more ROE will increase, this shows that broad disclosures provide a positive signal to interested parties and Corporate Social Responsibility does not affect the financial performance proxied in Earning Per Share (EPS), this is because the size of the companys EPS will not affect the disclosure of social responsibility by the company, it is possible because the number of shares circulating in the company is less than optimal.

Abstract

Oil palm expansion occurs massively in several regions in Indonesia, one of them is in Mamuju Tengah Regency. Area of oil palm plantations in the Year 2014 covering 25,220 Ha and in the Year 2016 increased to 45,562 Ha. The impact of expansion of oil palm plantations resulted in the ecological vulnerability of the soil becomes so dry that it is not suitable anymore planted with Rice and the explosion of the number of pest populations of rats that attack rice plants so that farmers often experience crop failure. This condition became the pressure that shook the livelihood of farmer households in Central Mamuju District. Agricultural data showed a decrease of harvested area of paddy in Central Mamuju Regency since 2010 of 29,627 Ha to 11,189 Ha. The objective of this research is to know the adaptation strategy of farmer household in facing ecological vulnerability behind oil palm expansion. The results showed that the farmers households did some coping strategies, such as: selling paddy fields, converting paddy fields into oil palm plantations, giving them paddy fields to work on others and he while looking for other job such as palm oil workers.

Abstract

The presence of communities in conservation areas provides chronic and systemic problems on land and biological resources and potentially to become agrarian-forestry conflicts. The existence is often interpreted as a threat that will impact on the occurrence of ecosystem crisis with the increasing intensity and scale of natural disasters that led to social-economic and environmental catastrophe. This paper deals with dilemma questions from the Dongi-dongi community, Sigi Regency, Indonesia on social justice or conservation, human or environment? The research employed qualitative descriptive method to decompose the source and root of conflict, while Analytical Hierarchy Process (AHP) was used to examine the implications of land conflict on socio-economic and environmental aspects. SWOT analysis directly directed to determine strategy for reducing conflict and agrarian-forestry crisis. The results show that agrarian-forestry conflicts can be reduced by prioritizing community-based forest management in terms of participation and collaboration (socio-economic and ecological aspects) through clarity of forest management structures and institutions, land tenure and utilization systems. In addition, avoiding conflicts through border setting and legitimacy. In this case, there should be a clear understanding that conversion of forest land to economic and environmentally insecure causes not only forest destruction but also natural disasters such as floods, drought, land erosion and socio-economic problems (declining quality of life, destruction local cultural arrangements and the loss of endemic flora and fauna species).

Abstract

The development of oil palm plantations has pushed for massive land-use change in Indonesia. As is the case in the District of Penrang, Wajo district. There are approximately 1,000 ha of agricultural land converted into oil palm plantations from 18,000 ha of land planned to be developed. The transformation of agricultural land into a palm oil plantation area with a partnership system has an impact on the limitations of the community in managing and accessing their land. Farming activities for both rice and other commodities such as cashew and others, and cattle grazing activities are no longer feasible on agricultural lands that have been planted for oil palm plantation. This condition triggers a shock to the livelihood system of farm households. Therefore, this study aims to analyze the vulnerability process and how communities conduct livelihood strategies to restore economic conditions and household livelihoods. This study used snowball sampling and indepth interview conducted in 2 villages namely Temmabarang village and Taddangpalie village, Penrang sub district. The results of the research indicate that there are some farmers households experiencing vulnerability due to land conversion in the form of vulnerability due to permanent disability due to workplace accident (shock), vulnerability in obtaining food (trend), and the vulnerability that forced the community to sell the assets (season) . And there is a change of income, asset ownership, expenditure, and resources that result in changes in the typology of livelihood strategies from the survival stage to consolidation in converting households.
