Abstract

Mt. Bromo is geographically located in eastern of Java Island at 112°57'30'' longitude and 7°56' latitude, with a large area of caldera ~10 Km2. The land over the volcano is a perfect area for farming, one of the important factor affects the level of soil fertility is the most mineral rich soils. Volcanic activities at Mt. Bromo has been recorded in 1775 which characterized by small eruptions with cycles ranging from one to five years. Regarding this evidence, we tried to investigate the surface changes over the Mt. Bromo by using Time-Series InSAR with TimeFun algorithm. TimeFun is an extension of SBAS to allow incorporating various functions such as seasonal oscillations, polynomials, and step functions as generally it estimates DEM errors as well and allows missing observation. The maximum allowed baseline value is defined and used to constrain the interferogram pair by selecting manual after differential InSAR processing in single face working. The proposed analysis is based on 27 SAR data sets acquired by the ALOS/PALSAR sensors during the 2007–2017 time interval. The result shows us deformation occurred up to ~10 cm at summit of Mt. Bromo during the eruption period. Time-series monitoring of surface deformation to infer volume changes, geometries and locations of sources of deformation involved in the future eruption

Abstract

The objective of the research is to improve fire risk reduction in Kampung Ampel Surabaya through: [1] identifying the current firefighting system in Surabaya; [2] identifying the characteristics and conditions of Kampung Ampel; [3] identifying structure of the problem; [4] proposing strategies for fire risk reduction in Kampung Ampel. The analysis will focus on determining risks and resources of Kampung Ampel to fire hazard using Geographic Information System (GIS) analysis. Risk and resources are combined to find out the areas that have the highest risk of fire hazard. The results of the analyses consist of challenges and possible solutions. The challenges can be concluded as follow: [1] resources for firefighting cannot cover the entire area of Kampung Ampel; and [2] resources for evacuation cannot accommodate all the population and visitors. The proposed solutions for those challenges are: [1] reactivation of inactive fire wells; [2] utilization on source of water in Ampel Mosque; [3] proposing wider road to connect roads which are wider than 3.5 meters but are blocked by narrower roads; [4] the purchase of adapters to connect different types of fire hoses; [5] adding the number of fire hoses brought to the site; [6] remodeling the vulnerable buildings using inflammable materials with keeping the value of cultural landscape; [7] keeping portable fire pump in Ampel Mosque to facilitate the fire handling by residents; and [8] preparing evacuation route to the closest open space areas. The application of those solutions can reduce the high-risk area from 26.6% to 0.2%.

Abstract

The flood hazard rating is one of the essential variables in flood risk analysis. The identification of flood-prone areas urgently requires information about flood hazard zones. This research explains the method to develop flood hazard map by using hydrodynamic modeling in the residential areas. The hydrodynamic model used in this research is HEC-RAS 5.0, which can simulate the one- and two-dimensional flow regimes. The study area is Bukit Sejahtera and Tanjung Rawa residences located in Palembang City with a total area of about 200 ha, where the Lambidaro River was frequently overflowing caused flood inundation in the area. There are five indicators of flood hazard being analyzed, i.e., 1) flood depth, 2) flow velocity, 3) energy head, 4) flow force, which is the result of multiplication between flood depth and the square of flow velocity, and 5) intensity, which is the result of multiplication between flood depth and the flow velocity. The simulation results show that the flood hazard rating in the study area ranges from high to low level. The zones with a high flood hazard rating are dominated by the area around or near to the river, whereas the further zones have a moderate and low level of flood hazard rating. The flood depth indicator has a more significant influence than the flow velocity on the flood hazard level in the study area. This research is expected can contribute to the development of flood map and flood control methods in advance.

Abstract

Ambient air temperature is main variable in climatological and hydrological analysis, however limited number of meteorological stations in Indonesia was becoming a problem to provide air temperature data for large areas.  The objective of this study is to generate air temparature using relationship of land surface temperature and vegetation index. A total of 6 climatological station and 84 MODIS Images for three years (2015 to 2017) were used for the analysis.  Research methods include: image georeferencing, band extraction from modis, derivation of NDVI, gererating ambient air temperature, calibrating using local meteorological station, and image interpretation. Results show that the accuracy of MODIS Surface Reflectance product to generate ambient air temperature in East Java at any periods is 86,37%. So MODIS Surface Reflectance product can be used as alternative solution to generate ambient air temperature.

Abstract

Household solid waste is the major environmental issue, not only in big cities but also in the suburban areas. Setia Asih Village location is in Kecamatan Tarumajaya, Kabupaten Bekasi. Bekasi is closed with Jakarta and it has unique characteristics, such as dual market economy; administration system; and social culture of the local people. Setia Asih Village has tremendous unmanaged household solid waste. It covers the land and river. This research paper used qualitative approach due to the limited of statistical data on the village level in Indonesia. The preliminary observation showed that local people do not have any knowledge or information about managing their household solid waste. Their local government does not have any responsibility to manage the household solid waste on the village level. It becomes local people responsibility. There is lack coordination among stakeholders in household solid waste management at Setia Asih Village. I conducted the solid waste management training to 300 people and Focus Group Discussion (FGD) with each Dusun (lower level than village) representatives. I found that local people have solutions to solve their household solid waste problem. Local government builds a new waste bank as Corporate Social Responsibility (CSR) from one of the state-owned enterprise.
