Analisis Bahaya dan Resiko Bencana Gunungapi Papandayan (Studi Kasus: Kecamatan Cisurupan, Kabupaten Garut)
Get PDFRisk assessment is an important step to be carried out for disaster management. It provides information for decision makers and communities in pre-disaster, during disaster and post disaster event. Nevertheless, risk assessment in Indonesia, especially on active volcanoes is still limited. This paper presents the risk assessment of Mt. Papandayan (2.665 m), the most active volcano in West Java. The unit of analysis in this study follows the administrative boundaries of village so that the identification can be applied at village level using GIS. Hazard analysis refers to the official hazard map produced by PVMBG while the vulnerability analysis is carried out in 3 sub-analysis, physical vulnerability (7 indicators), social vulnerability (7 indicators), and economic vulnerability. The hazard and vulnerability were overlayed in order to produce the risk which is subsequently made into risk map. The findings indicate that the villages located near and on the direction of the crater have relatively higher risk compared to other villages. The risk map can be incorporated as one of references for spatial planning that integrates disaster mitigation

Field observation and analysis of morphology, topography and physical characteristic of the coastal area of Pancer has been done in this research. Interview with key person and stakeholders has been conducted in order to understand the awareness system and program done by the community. Descriptive analysis has been used to describe the research result. From the topographical point of view, study area consist of lowland and hilly area. Lowland area is dominated by settlement and paddy field, meanwhile the hilly area is mainly for forest and dry farming system. Lowland area is the most vulnerable area for inundation due to tsunami. Coastal community has knowledge on tsunami hazard. Many program has been implemented to strengthen the community capacity and awareness, such as campaign, workshop for evacuation route identification, and evacuation simulation
Penilaian Kerentanan Pantai menggunakan Metode Integrasi CVI-MCA Studi Kasus Pantai Indramayu
Get PDFThe increasing of sea level due to climate change has been focused many research activities in order to know the coastal response to the change, and determine the important variables which have contribution to the coastal change. This paper presents a method for integrating Coastal Vulnerability Index (CVI), Multi Criteria Analysis (MCA) method and Geographic Information-System (GIS) technology to map the coastal vulnerability. The index is calculated based-on six variables: coastal erosion, geomorphology, slope, significant wave height, sea level change and tidal range. Emphasize has been made to the methodological aspect, essentially which is linked to: (i) the use of GIS technique for constructing, interpolation, filtering and resampling the data for shoreline grid, (ii) the standardization each rank of variables (0-1) and the use of several percentile (20%, 40%, 60%, and 80%) for each rank score, and (iii) the use of variable’s rank to map the relative (local) and standard (global) vulnerability of the coastline. The result show that for local, the index consist of four categories: very high (19.61%), high (68.63%), moderate (1,96%), and low (9.80%). Meanwhile, for global level, the index is constantly in low category
Hidrostratigrafi Akuifer sebagai Geoindikator Genesis Bentuk Lahan di Wilayah Kepesisiran Kabupaten Kulonprogo, Daerah Istimewa Yogyakarta
Get PDFPurpose of this research is to study on aquifer hydrostratigraphy that can be a geo-indicator of geomorphological processes on the past, that describe of landform genetic in the research area. The research method is survey. The framework of analysis in this research is landform genetic. The results of the research indicate that: (1) "the forming of aquifer hydrostratigraphy in the research area is controlled by some of main processes in geomorphology, that show of landform genetic specifically". The research area consists of 3 aquifer hydrostratigraphy systems, each of the aquifer system has the typical characteristic, showed by system and pattern of material stratigraphy in the aquifer and variation of groundwater characteristic in the unconfined aquifer. (2) "spatiotemporally, landform genetic in the research area influences on the forming of aquifer hydrostratigraphy in the 3 phases, i.e. the first stage at the end of the Tertiary epoch (end of Pliocene era), second stage at the Quaternary epoch (as long as the Pleistocene period), and third stage at the Holocene era". The genesis and chronology of landform forming in the 3 phases above influence on the forming of system and pattern of aquifer hydrostratigraphy in the research area
Analisis dan Estimasi Dampak Longsorlahan terhadap Jaringan Jalan di Kecamatan Samigaluh, Kabupaten Kulonprogo
Get PDFIn this study, direct risk assessment was developed for various scenarios on the basis of hazard (e.g. spatial probability, temporal probability and magnitude class), vulnerability and estimating cost of road damage. Indirect risk assessment was derived from traffic interruption. The impact of landslide both direct and indirect impact were analyzed in the road segment 174. The research results show the highest direct impact of debris slide type of magnitude I located in the 20th mapping unit.

Kebutuhan Luasan Areal Hutan Kota sebagai Rosot (Sink) Gas CO2 untuk Mengantisipasi Penurunan Luasan Ruang Terbuka Hijau di Kota Bogor
Get PDFThe purpose of this study was to determine the need of the urban forest area as sink (sequestration) of CO2 gas from fuel oil and gas in Bogor City. Analysis of dynamic system is used to determine the need. Powersim software with the license number PSSL-N999998-5NC2Y was used in this research. Satellite imagery in 2003, 2005 and 2007 were used to analyze the extent of green space and built space as well as percentage changes. This study revealed that the urban forest area required as well as the number of seedlings are varies according to time and the sink rate. Therefore, the selection of tree species based on the sink rate should really be considered. By using the very high-sink rate trees, the area needed for this purpose will be smaller and can also make lower the ambient concentration. On the other hand, when the use of high-sink trees, the ambient concentration of this gas will increase again and the urban forest area that needed will be larger
