Abstract

Strengthening geospatial technology is very important in order to support disaster mitigation strategy, to manage vulnerable communities and to protectcritical environments. The main challenge in identifying disaster characteristics such as mass movements is the lack of direct observation during the event because it is too dangerous for researchers. Geo-Information Technology as a product of Geographic Information Science can be used as a solution in order to model the characteristics of mass movements. The purpose of this study is focused on identifying landslide processes from point of view ofraster-based model. The method of thisresearch emphasizes dynamic landslide model derived from timeseries raster calculation using MassMov2D algorithm. The geographic database that was built for spatial modeling comes from pedogeomorphological and Remote Sensing survey outputs, especially topographic data, landforms and soil physical properties. The result shows that the relationship between pixels (neighborhood) is determined by the topology of the energy gradient line direction which allowsto transfer the value between each pixel.The movement of landslide material starts from the toe. This decreases the stability of the landslide material in the main body of the landslide and generate progressive erosion.The raster-based model can finally reconstruct and identify the stages of initiation, transport and deposition landslide material.

Abstract

Among various issues on regional development planning in Indonesia, the vast coverage area and its regional diversity become one of main challenges. Regionalization is one of spatial techniques that can be used to facilitate regional development planning process. This study aims to analyze regionalization of Indonesia with a focus on Java Island by highlighting the main contemporary issues including poverty, COVID-19 pandemic, and gender. This paper draws the conditions of poverty, the cases of the COVID-19 pandemic and the needs of gender-based development in 119 regencies/cities on the island of Java using spatial distribution analysis. The results of the analysis show that the distribution of the percentage of the poor and the poverty line in Java forms a clustered pattern. This also happened in the case of COVID-19 where the high concentration of cases was around DKI Jakarta and DI Yogyakarta. As for the gender aspect, there is a tendency for a scattered pattern for the value of the gender development index, although there are some areas with high values (H-H quadrant) and low values (L-L quadrant). In general, the use of regional analysis may facilitate the identification of spatial phenomena, their distribution and the patterns formed, therefore it can be used for determining suitable regional policies.Keywords: Java Island, Regionalization, Poverty, COVID-19 Pandemic, Gender
