Authors: Lestari D A , Sakti B 
Published: September 2020

Abstract
Earthquakes are still a major issue in Indonesia, one of the earthquake-prone areas is Lampung Province. There are many sources of earthquakes in Lampung, due to the influenced by the Indo Australian Plate against the Eurasian Plate, Semangko Fault, and Tarahan Fault. Tarahan Fault that passes through Pringsewu district and Bandar Lampung City is an active fault where the west side of the fault force moves to the northeast. Judging from the occurrence of the earthquake so far, it should be taken into account the possibility that there is a large buildup of energy in the Lampung area, one of them in Pringsewu. One of the efforts in earthquake disaster mitigation is to know the level of vulnerability, in this study based on its social aspects. This social vulnerability can be known through social vulnerability analysis or Social Vulnerability Index (SOVI). This analysis uses a comparative matrix that gives a broad picture of social vulnerability relative to earthquake hazards. The results showed that the regions with very high social vulnerability were in Gading Rejo Subdistrict while the low social vulnerability was in Ambarawa, Banyumas and Adiluwih Subdistricts.

Abstract
Flood, landslide, and Tsunami was a disaster that has highest casualties in Indonesia. Based on BNPB’s data on 2019 flood, landslide, and tsunami cause more than 1000 people died or gone. Cisolok Village is one of many areas in Indonesia that has a potential hazard of that three disasters. Cisolok Village has flat and mountainous land-form from zero until more than 25%. slope gradient. There are two rivers that stream on Cisolok Village’s west and east side. Moreover, Cisolok Village has a beach with cliff type. That’s physical characteristic of Cisolok Village can cause the settlement become a prone area. This research is aim to do multi hazard mapping and also to know distribution of flood, landslide, and tsunami hazard and prone areas in Cisolok village. Variable of hazard in this research are slope, distance from river, landform, and altitude. While the prone’s variable is location of settlement in Cisolok Village. Overlay Method was used to create hazard map and prone map. Spatial analysis was implemented to describe the distribution of flood, landslide, and tsunami hazard and prone areas in Cisolok village. The result show that there are areas with high flood, landslide, and tsunami hazard potential in Cisolok Village. High and very high landslide hazard potential area has the largest area (26.6 Ha) than the others. While, Tsunami prone area with high class has the largest areas (8.10 Ha) than the others. Southeast side of Cisolok Village is the prone area with high class in flood, landslide, and tsunami hazard.

Abstract
The water quality in the northern coastal waters estuary of Central Java has been polluted at a moderate to severe level. Water quality monitoring efforts for evaluating the condition of dissolved sedimentation can be done through total suspended solid methods by analising the remote sensing imagery. Total suspended solid (TSS) is measured by suspended material (diameter> 1 µm) which retained in the millopore filter with a 0.45 µm pore diameter. The purpose of this research is to assess the distribution of TSS concentrations in the research location. This study was conducted using Landsat 8 image data on August 9th, 2018. TSS concentration values were obtained through linear regression tests Doxaran algorithm which is the most suitable algorithm with the field condition. The results showed that: 1) The appropriate empirical algorithm for mapping TSS concentrations is the Doxaran algorithm with the TSS equation = 1.0248x - 10.503, 2) Distribution of TSS with the range >75 mg/l mostly concentrated in center and west of the study area, while the concentration with range <75 mg/l is concentrated in the east, and 3) Distribution of TSS is affected by the movement of currents driven by the wind towards the west and southwest and partly collected in the western part of the study area.

Abstract
Research on mangrove forest biomass using drones was conducted in Karimun Jawa Islands in August 2018. Karimunjawa Islands is a conservation area under the management authority of the Ministry of Environment and Forestry (KLHK). However potential environmental stress due to increasing numbers of tourists and aquaculture activityis concerned to degrade mangrove ecosystem in the area. The method used in this study includes aerial photography work using drones and field data collection of forest ecosystems. Aerial photography work consists of stages of preparation, aerial photography and aerial photo processing in the form of photos mosaicking and DSM generating. The mangrove field data obtained were tree diameter (DBH), tree height and mangrove genus. To find out the mangrove biomass, the equation Saenger & Snedaker (1993) is used. The results show that the number of branches of mangrove trees are 853 branches with heights varying between 1 to 15.5 meters and an average height of 4.4 meter. The estimated mangrove biomass in the study site is 82,154 tons/hectare. This study successfully demonstrated that by using relatively low operational cost consumer-grade drone and can help map the characteristics of mangrove vegetation. However, drone technology still has some limitations, including the need to use GPS Geodetic for accurate positioning. Using this supporting technology, it is expected that the position and height of the tree can be measured more accurately.
Distribution patterns of redox potential in intertidal zone of Blanakan coast and their implication on the coastal ecosystem
Authors: Takarina N D 
Published: September 2020

Abstract
The intertidal zone of Blanakan Coast has an area of approximately 15 ha. The Blanakan Coast itself is important fishing ground. Correspondingly, a study to assess the water quality in the coastal ecosystem is important. One of important water quality parameters is reduction and oxidation (redox/Eh) potential since it can indicate the anoxia condition. Nevertheless, the detailed spatial variation of Eh is poorly understood, especially in intertidal zone where anoxia may be a significant environmental constraint for marine organism. The Eh data were recorded from 7 sampling points in intertidal zone. Based on the result, the mean value of Eh is ranging from -20.0 to -50.67 mV. The poorest intertidal zone was found in the sampling point closed to the river mouth with mean value of Eh is -50.67 mV. Another poor intertidal zone was found in the eastern part of intertidal zone closed to the coast with mean value is -46.16 mV. The better condition of intertidal zone was found in the northern and western part of intertidal zone with mean value is -25.16 mV. The study also found that value of Eh is significantly correlated with the value of dissolved oxygen (DO). The DO is high when the value of Eh is high and the DO is low when the value of Eh is low. For example, the -50.67 mV redox potential significantly reduced the DO in the intertidal zone as low as 1.56 mg/l. Thereby, this Eh can cause anoxia condition in ecosystem of intertidal zone especially near river mouth and east side.

Abstract
Derawan Island is an island with an area of 45 ha, it categorized as a small island and part of Derawan Islands archipelago located in East Kalimantan province. It designated as a conservation area by the decision of Berau District Head No. 516 of 2013 concerning the Reservation of Coastal Conservation Areas and Small Islands. Derawan Island, also known as the National Tourism Destination (DPN) based on its coral reefs diversity that considered adjacent to the Coral Triangle Initiative (CTI). The increase of Tourist visits to Derawan Islands since 2000, which affected land cover changes in Derawan Island coast such as for lodging, jetty and other infrastructure. Changes in land cover together with natural coastal processes causing abrasion in the west, and east sides, while accretion in the southeast side of the island. Land cover change especially built-up area from 2003 to 2018 is 6.25% per year. Observations and analyzes using DSAS (Digital Coastline Analysis System) conducted in 2003, 2011 and 2018 illustrates coastline change which shown by abrasion an accretion along Derawan Island. Abrasion trends increased from 2003, 2011 and 2018 with the highest abrasion rate up to 12.4 m / year, which occurred on the west side, while the highest accretion rate was 2.46 m / year on the southeast side. Based on several considerations and conditions, it is highly recommended that the coastal border for utilization in the islands is around 15 m.

Abstract
For years, the Province of West Java has been facing several development challenges, such as poverty, malnutrition, low access to education, etc. It is assumed that the characteristics are patterned. The aim of this paper to present the typology of socio-economic characteristic of municipalities and regencies in West Java Province. By combining cluster and spatial cluster analysis, we figured out that the three cluster of areas represented the domination of examined regional development variables. Spatial cluster analysis employs the spatially weighted variables to form a homogenous cluster of each region in West Java. The first cluster can be classified as peri-urban area (area surrounding urban region) with average-sized population, unemployment, and malnutrition size. The second cluster can be classified as rural area with small population, unemployment, and malnutrition size. The third cluster can be classified as urban area with high-sized population, unemployment, and malnutrition size. We concluded that well-developed municipalities and regencies are concentrated in the western part of West Java, a particular area that is has a close proximity to the capital city of Indonesia.

Abstract
This research aims to investigate the responses of students with disabilities to earthquakes. To achieve the goal, this study investigated the perception of evacuation plans for earthquakes among students with visual impairments (n=32, junior and senior high schools) and their teachers (n=12) using in-depth interviews. The questions asked to the respondents encompassed the knowledge and experience of earthquakes, safe school buildings and designs, evacuation plans, and assistance during emergencies. An evacuation simulation for earthquakes was also performed to understand the ability of students to protect and evacuate themselves from earthquakes. Testimonials were also noted from students and teachers after the simulation to understand interventions needed to improve the students’ response in facing earthquakes. The interviews and simulation processes were recorded using voice and video cameras, respectively. A qualitative content analysis was used to scrutinize the responses obtained from the interviews and evacuation simulation for earthquakes. The results of interviews showed that the majority of SWDs show poor (n=22) responses to earthquakes. Only a small number of students show moderate (n=4) and good (n=1 people) responses to earthquakes. The interviews revealed aspects need improvements, including the knowledge about earthquakes, reaction time to earthquakes, self-protection and evacuation procedures, safety of school buildings, and design of school building to support swift evacuation. Furthermore, the simulation for earthquakes exposed that the students are vulnerable to earthquake disasters. In addition to the lack of ability to protect and evacuate themselves during earthquakes, the students are not prepared mentally to face earthquakes. Capacity building through regular evacuation simulation for earthquakes, knowledge improvements in earthquakes, and self-protection training is likely to reduce the risk of being adversely affected by earthquakes.

Abstract
According to Sutopo, Head of the BNPD Data, Information and Public Relations Centre, the earthquake disaster that occurred in Palu, there were 1,948 fatalities, 843 missing, and it is estimated that many victims were buried in the estimated figures until they reached thousands (BCC Indonesia, 2018). The losses suffered are also estimated to be very large. Preparedness is one part of the disaster management process and in the current developing concept of disaster, the importance of preparedness is one of the important elements of proactive disaster risk reduction before a disaster occurs. (LIPI-UNESCO, 2006). The object of this research is the people of Palu who live in Temporary Resettlement in several locations, namely Petobo, Balaroa, Silae, Lero, and Kampung Baru. This study uses economic modelling methods to determine the relationship between variables and as many as 150 people are sampled in the collection of data needed. The variables of this study are age, education, occupation, and aspects contained in the disaster risk reduction index (Carreno et al., 2004). The conclusion is that age is very influential on emergency response planning and implementation of warning systems as well as community preparedness and training, on the other hand education and employment have no effect at all in the DRR index. Therefore, there needs to be an evaluation from both the local and central government, the community, and academics to think about ways to reduce disaster risk by increasing public knowledge of disasters

Abstract
Slums are one of the urban problems that occur in almost all regions in Indonesia. As one of the pillars of sustainable development, and to deal with problems related to slums, every City / Regency based on Government Regulation are required to prepare RP3KP documents as a master plan for regional settlements. Jember is one of the areas in Besuki Raya that already has housing and settlement planning products but is still in the RP4D format. Based on these conditions, Jember is categorized as a district that does not have a settlement area planning instrument that meets the standards. In fact, there are 37 villages classified as slums with an area of 47.2 ha, uninhabitable houses reaching 3,940 units in slums in Jember Regency (Kotaku,2017). The results of the study is useful as a basic reference in the formulation of residential area planning policy in Jember Regency. With the typology and formulation of priority infrastructure needs analysis in slum areas, a general description of the condition of the characteristics of slums in Jember Regency can be described. The results show that physically, the infrastructure to be aware of are road infrastructure, building conditions, waste management and fire danger

Abstract
The phenomenon of Urban Heat Island (UHI) will be exacerbated in the coming years by rising surface temperatures due to urban growth. Implementation of urban green infrastructure (UGI) such as green roof, green wall, parks, road trees can help reduce temperatures in urban areas, including reducing pollution. Currently, there is no information available for land managers to determine the right strategy for UGI implementation based on a spatial approach. So that a framework is arranged to determine UGI priorities and elections in creating a compact eco-city. The framework is supported by a review of scientific literature related to UHI phenomenon in Surabaya, UGI and urban heat island mitigation in comparative descriptive and gap analysis. UGI implementation priorities are allocated based on observing the location of urban heat island using Landsat 8 OIL TIRS, behavioral Exposure and spatial land-use patterns are taking a result in Kali Rungkut sub-district, East Surabaya.

Abstract
Climate change is inevitable and adaptation is a must. Surabaya as an urban area that contributes to the phenomenon of global warming. The challenges of the City of Surabaya in managing the impacts of climate change need to be further considered. On 21-22 February 2018, the City Government of Surabaya joined the Climate Change Adaptation Workshop. In managing the impacts of climate change, it is necessary to synchronize national, regional and local government policies and create SOPs for climate change adaptation actions. In addition, another priority is spatial planning that takes into account climate change in the context of development. Responding to the suggestions expected from the workshop, this research focuses on assessing risks due to climate change involving institutional aspects. This institutional aspect was taken with the intention of providing recommendations to managers and decision makers in making processes and designing policy analyzes to reduce and adapt to climate change. The results showed that there were six Surabaya City Organizations that were considered to have significant influence and interest in the field of climate change. In addition, historical disaster data on climate change has been derived, which states that disasters in Surabaya include floods, whirlwinds (extreme weather), drought, and forest and land fires. Based on the Likert scale scoring calculation results, it is known that the Surabaya City Organizations resilience a with the CDRI concept is 4.47. This figure indicates that the resilience level of the City of Surabaya is seen from the institutional aspect is relatively high and needs to be maintained.
A brief introduction to LENSOLVER as linear programming application
Authors: Pratomoatmojo N A 
Published: September 2020

Abstract
Linear programming technique is a model that can be used to solve the problem of allocating resources with limited conditions. This technique is often used to solve problems in several good fields. Linear Programming is a deterministic tool in which all model parameters are assumed to be known with certainty. In addition, the use of linear programs can be used to make decisions from various alternative objectives in the form of activities or strategies, where there are constraint functions considered. In this paper introduces LENSOLVER, as an application of linear programming application. In this early stage of development, LENSOLVER is developed based on the PuLP framework. PuLP is a library for the Python programming language that allows users to create mathematical programs for problem-solving optimization and decision making by means of calculating variables using mathematical expressions. However, this first development of LENSOLVER has a limitation of not supporting non-linear optimization. Considering the ease and reliability LENSOLVER was developed to reach non-programming users who want to implement various linear programming techniques in several cases in operations research.
