Abstract

Forest and land fires (Karhutla) is one of the disasters that frequently hit Indonesia every year. Assessment for Karhutla's hazard, vulnerability and risk is an important early instrument for determining future disaster mitigation measures. The purpose of this study was to perform disaster risk assessment for Karhutla based on forest and land fires hazard and social vulnerability in the Regency of Serang. This particular hazard, vulnerability and risk analysis was based on the guidance outlined in the Head of BNPB Regulation No. 2 of 2012. The analysis results show that 46.87% of the total settlement area in the Regency of Serang falls into the low risk class of Karhutla. Meanwhile, medium and high risk class of Karhutla accounted for approximately 37.78% and 0.90% of the total settlement area in the Regency of Serang, respectively. Future detailing is needed to obtain more detailed results in the future.

Abstract

ABSTRACTPulo Ampel Industrial Zone in Serang Regency is an industrial zone with a high level of threat from a technological hazard. One possible route this threat can be manifested is in the form of explosion potential from the storage and transport tanks of toxic and dangerous materials e.g. Ethylene and Butadiene gases. Within the framework of disaster risk reduction, disaster risk analysis is carried out which includes the analysis of threats and vulnerabilities along the path of transport of these hazardous materials. To determine the level of explosion hazard, due to the occurrence of transportation accidents, modeling using ALOHA® (Areal Locations of Hazardous Atmospheres) software, which was developed by the United States Environmental Protection Agency (US EPA), was carried out. The model used in this study was the BLEVEs (Boiling Liquid Expanding Vapor Explosions) scenario during gas transportation using ISO Tank, which represents the worse possible scenario. Meanwhile, disaster vulnerability analysis is calculated based on social vulnerability aspect which includes population density and vulnerable group parameters by utilizing the scoring method in accordance to Head of BNPB Decree No.2 of 2012. Based on the hazard and vulnerability level, disaster risk maps are obtained along the Ethylene and Butadiene transport lines covering the information related to the area of the explosion which intersected with population settlement in Serang Regency, Banten Province.Keywords: risk reduction, trasportation, hazardous materials, vulnerabilities, explotionABSTRAKZona Industri Pulo Ampel di Kabupaten Serang merupakan zona industri dengan ancaman bencana kegagalan teknologi yang relatif tinggi.

Abstract

Zero Delta Q is a policy to ensure that any additional surface runoff due to development does not further burden the drainage or river system. In case of Zero Delta Q application planning at the community level, a software is needed that can help classify and quantify the existing land cover class in area where the community is located. The purpose of this study is to look at the time needed and reliability of the i-Tree Canopy web-based software online in classifying and quantifying land cover classes on one of the sub-catchments in the Pesanggrahan River Basin. The land cover class is divided into six: trees, grasses / undergrowth plants, open area, water bodies, pavement / road and roof of the building. For comparison, an RBI map is used from the same area to see the extent of each class of land cover. Observation of each point requires an average time of 5.2 ± 1.0 seconds. The difference between direct sub-basin measurements using i-Tree Canopy and detailed analysis results from the RBI map is within the range of 0.41% or 0.36 Ha for each individual class of land cover. For a relatively small study area (under 100 ha) and when supported with reliable internet access, this web-based online software is sufficiently reliable in assisting the application planning process to support Zero Delta Q policy.

Abstract

Obi Island possess substantial natural resource potential in the form of nickel ore. Since 2014, exports of raw mineral resources have been banned and the government obligate the construction of smelters. The amount of energy and water needed for smelter requires careful planning in relation to the potential water resource available in proximity to smelter construction site, which in this case is Lake Karu. The purpose of this study was to determine the condition of the structure and composition of vegetation in the catchment area of Lake Karu. Data collected were diameter at breast height (dbh) and height of vegetation from each growth state (seedlings, saplings, poles and trees). Sampling method used for vegetation data collection were in the form of a plot in a transect. The measurement results obtained from field surveys were then analyzed to obtain the Important Value Index (IVI) of each type of vegetation and Shannon-Wiener diversity index. From this study it is known that there are three classes of lowland forest in the study location. When sorted from the most diverse to the most uniform, the sequence is: heterogeneous lowland forests, forests in river corridors and homogeneous lowland forests. Forest conditions in the study sites are in good condition and further research is needed to add more depth to this study.

Abstract

Landslides are the third most frequent disaster in Indonesia. One of these landslides occurred on March 10, 2017 in residential area of Jatiradio, Cililin Village, Cililin Sub-District, West Bandung Regency, West Java Province. Post-incident investigations have produced information regarding the characteristics of the area and recommendations for disaster mitigation. At present it is known that there are still problems left unsolved in the area that need to be mitigated. The purpose of this study is to identify those unsolved problems at the study site and formulate solutions to the problem using a soil bioengineering approach. Among all the data that need to be collected are the condition of both existing vegetation and subsurface profile on the former landslide slopes at the study site. Data from the observations were then analyzed to produce recommendations regarding the application of soil bioengineering at the study site. From this study, pine trees (Pinus merkusii) is recommended to be planted on the slopes and areas around the rock gabions. This type of vegetation has fulfilled four pre-determined criterias related to the function of slope protection and groundwater regulation for this particular area and is considered suitable to be applied to the study site.

Abstract

Floods are the most common disaster in Indonesia. Among various flood types, pluvial flood is the least studied one. Simple rain water harvesting system using cistern/barrel and water tank possess the potential to reduce runoff from roofs and help alleviate the severity of pluvial flooding. The purpose of this study was to simulate the application of simple rain water harvesting in reducing surface runoff from roof surfaces in the study area within the sub Basin of Pesanggrahan. Among all the data that need to be collected were the number of houses and area of roof cover in the study area, as well as 10 years rainfall data. Number of houses per block were collected during a field survey while the estimation of roof area was conducted using a web-based software, i-Tree Canopy. From this simulation, scenario 1 (800-liter water drums), has the potential to reduce surface runoff from the roofs within the range of 6.12 to 9.07% (January) and between 5.08 to 7.49% (February). Meanwhile scenario 2 (2000-liter water tank) has the potential for surface runoff reduction which ranges between 15.30 to 22.67% (January) and between 12.64 to 18.73% (February). On the other hand, the potential to delay the initial surface runoff time using scenario 1 ranged from 3.7 to 5.5 minutes (January) and between 3.1 to 4.5 minutes (February). Meanwhile scenario 2 has a potential to delay the initial surface runoff time from 9.3 to 13.7 minutes (January) and between 7.6 to 11.3 minutes (February).
