Abstract

This research was proposed to figure out the importance of human influence on landslide disaster. The research objectives were: (1) to map the locations of landslide during the period of January 2004-March 2008 of the study area; (2) to map the degree of landslide hazard of the study area; (3) to analyze the distribution of landslide based on the landslide hazard map; and (4) to analyze the distribution of landslide based on the road network. The method of this research consists of field survey and laboratory works. The field survey was intended to map the location of landslide which happened during the period of January 2004 up to March 2008. The land characteristics and land qualities data have been collected based on geomorphological approach. The laboratory works were proposed to analyze the field data of land characteristics and land qualities for landslide hazards classification and mapping purposes. Scoring method was applied for landslide hazard evaluation. Some geographical information techniques were applied for mapping purposes and spatial data analysis of landslide distribution. Map overlay and buffering techniques were applied during landslide distribution analysis. The results of the research showed that: (1) there were 291 landslides collected during the research period; (2) the study area consists of very high, high, moderate, and low of landslide hazard classes. There was no safe area of landslide hazard within the study area; (3) most the landslide occasions were more influenced by human activities than derived by physical conditions. Some of human activities that induced landslide in the study area were slope cutting for: road construction, houses, agricultural purposes, and sand and stone mining in the river canal; (4) the spatial distribution of most landslide ( 90%) were parallel with road networks.

Abstract

Some cities in Indonesia which are located on Southern Java Island are susceptible to tsunamis. However, the application of participatory GIS for the assessment of building vulnerability to tsunamis remains rarely evaluated. The aims of this research are 1) to obtain the parameters of building vulnerability to tsunamis using the participatory approach, and 2) to evaluate the results of building vulnerability assessment using participatory GIS. A tsunami inundation map was constructed based on numerical modelling using the Hawke's Bay equation. Participatory approaches were taken to establish the parameters that affect the vulnerability of buildings to tsunamis using in-depth interviews. Respondents were selected using the purposive sampling technique. A geographic information system (GIS) was then applied to build a geodatabase and to perform analysis. The results show that six parameters were obtained from local people’s participation, namely building materials, the number of stories of the buildings , orientation, preservation condition, building row, and natural barriers. All the parameters were identified and interpreted using aerial photos. A field survey was conducted to complete the information on building characteristics. Many buildings near the beach were classified as having high and moderate vulnerability. The main benefit of participatory GIS is that the role of the community makes a significant contribution to providing vulnerability information. It also raises public awareness and improves preparedness for disaster risk management. The drawback is that parameters based on participatory approaches are dynamic and may be different in other areas.

Abstract

This research aims at identification of spatial plan zonation in rock fall prone areas. Research method applies hazard, vulnerability and risk analysis as an input for spatial modeling using Multi Criteria Evaluation (MCE). Research reveals that in Girimulyo is susceptible towards rock fall. In the last decades, there were 16 occurrences of rock fall that impacted to physical damages. Fortunately, such disaster did not cause any harm to human life. Therefore, research argue that physical vulnerability analysis can be analyzed, while social vulnerability cannot be analyzed further, since it had less data support. According to the research, there are more than 48 housing units located in hazard zone. Hence, local government should initiate structural mitigation to avoid further loss. Research also reveals that areas with high susceptibility will not directly consider as high risk zone, unless it has high vulnerability index. Example: areas along escarpment, where it has high susceptibility, but it has no element at risk in the area. Thereby, research tries to present zonation for prone hazard areas, using risk index. The result is quite representative, since possible areas to be developed is anywhere alongside road network. Indication of the area is produced from the multi criteria analysis. Multi criteria analysis is an essential method to combine spatial data and its attribute. Using such method requires more data input and expertise in justifying indicator to be selected.

Abstract

Land management is a manifestation of the society’s behaviour in utilizing the land. The objective of the research was to examine the effect of education level, income, land tenure, knowledge, and information input on the society’s behaviour in managing the area susceptible to landslide in Pekuncen sub-district, Banyumas district.   The method of this research was survey by employing questionnaire to collect field data. The variable comprised of the data of education level, income, land tenure, knowledge, and information input.. Stratified random sampling was applied to determine the samples of the research. The area susceptibility class  was considered as the strata in which each stratum consisted of 40 family heads as the respondents. The data analysis applied statistical test of multi-regression. Research area was divided into three classes of landslide susceptibility comprising of low, medium, and high class. Education level, income, land tenure, knowledge, and information input significantly influenced the society’s behaviour dealing with land management (determination co-efficiency (R²) was 69.9 %). It occurred in the area of medium susceptibility class. Information input (regression coefficient/(beta) = 0.817) was the most influential predictor of society’s behaviour in land management located in the low susceptibility class. From this research, it was expected that the description about the factors that influenced the society’s behaviour in managing the landslide-prone area would be a valuable reference in preventing landslide in those areas.

Abstract

The objectives of this research were 1) to determine soil moisture regime based on rainfall and temperature data; 2) to make a correction of the first objective based on soil moisture surplus and deficit calulation; 3) to study the pattern of soil moisture regime distribution in the research area. The field sampling tehniques applied in this research was stratified proposed sampling. Landform unit was applied as strata. Soil depth and texture were considered during field soil sampling within the landform unit. Rainfall and air temperature data were analyzed using Newball Simulation Model (NSM) to determine a tentative soil moisture regime. The tentative soil moisture regime was corrected using calculation soil moisture regime of soil moisture surplus and deficit. The soil moisture surplus and deficit was calculated based on soil depth, soil texture, rainfall, and temperature data. The result of this research were 1) soil moisture regime estimated using NSM ranged from ustic to udic; 2) soil moisture regime corrected using surplus and/ or defiit alulation of soil moisture ranged from xeric to udic; 3) the pattern of soil moisture regime distribution in the reaserch area was not only controlled by the pattern of rainfall – air temperature distribution but it was also controlled by the pattern of soil – landform distribution. Under the some amount of annual rainfall, shallow and coarse texture soils have drier soil moisture regime than deep and fine texture soils.
