Abstract

The purpose of this study was to determine the extent of changes in land cover around the Mount Sinabung area after the 2009-2019 eruption by monitoring through remote sensing imagery and GIS. The method used in this research is descriptive quantitative. The technique of data collection used document study techniques by collecting Landsat images are among the widely used satellite remote sensing data and their spectral, spatial and temporal resolution made them useful input for mapping and planning projects (Sadidy et al. 1981). Changes in land cover that occurred around the Mount Sinabung area were dominated by pyroclastic material due to eruption. In addition, changes in land cover also occur due to the abandonment of potential lands, such as local residents who work in the plantation sector are forced to leave that, so they eventually turn into shrubs. The direction of the dominant pyroclastic material slides was directed towards the east-south and southeast of Mount Sinabung, where the area was dominated by the plantation sector. The impact of the eruption of Mount Sinabung was directly and indirectly. The total land cover changes due to pyroclastic material in 2010 was an area of 26.27 Ha, in 2014 it was 475.82 Ha, 2017 was 1339.75 Ha, and 2019 was 1196.11 Ha.

Abstract

Approximately 40% of Jakarta is below sea level when the tide is in, which is referred to as a fluviomarine landform. This study aims: (a) to analyse the relationship between total income and household water demand, and (b) to analyse the relationship between total income and the proportion of groundwater utilization. It uses quantitative and qualitative analysis survey methods, as well as sampling methods, to represent the population. The population of this research is comprised of households that use groundwater on land units made from two classes of landform, two classes of settlement pattern, and three classes of settlement density. To determine the 30 wells, samples with proportional random sampling of the land units formed with groundwater samples have been taken at a radius of 100m from each well sample of 110 households. Quantitative and qualitative approaches have been used to prove the research aims. The analysis of this study indicates that the total income is proportional to household water demand but that it is inversely proportional to the share of groundwater utilization. The results also show that groundwater is not the only source to fulfil household water demand, and that it is necessary to utilize other sources of water.

Abstract

Research and development of Robot Vision activity requirs a Moving platform with high mobility on translation as well as rotation movement. Omnidirectional vehicle reported here has optimum planar movement in the form translational movement on any direction as well as turning radius from zero to infinity, therefore it is suitable as a moving platform for research activities on 2 dimensional Robot Vision. Testing and measurement on the accuracy of vehicle straight trajectory on different direction have been carried out. Some error compensation algorithm has been applied and some good results on reducing trajectory errors have been observed.

Abstract

This study aims to determine the capacity of the Bayah coastal area in dealing with the tsunami disaster. The research method used in this research is descriptive method. This study is a population study consisting of 4 villages, including Sawarna Village, East Sawarna Village, West Bayah Village, and Darmasari Village. The unit of analysis in this study is the region. In this study the instrument used was a questionnaire as a guide to interview respondents who represented the area under study. The assessment of regional capacity in disaster management is carried out by looking at the four priorities of disaster risk reduction programs. These priorities are adopted in the Hyogo Framework for Action (KAH). With the following priorities: 1). Disaster education 2). Early warning and disaster risk assessment 3). Reduction of basic risk factors 4). Development preparedness on all lines. The results of this study indicate that the Bayah Coast region in the face of tsunamis has a low capacity of 18.7% which falls into the level 1 category. The area has had small achievements in disaster risk reduction efforts by implementing several advanced actions in plans or policies . This shows that the regional capacity in implementing disaster management is still very lacking, requiring intensive capacity building. Keywords: Capacity, Hyogo Framework for Action, Tsunami

Abstract

AbstractThis study is intended to identify spatial condition of rice production in 2010-2013 and it’s related factors to support foods security in Bekasi District. It uses secondary data from various agencies, while the analysis is spatial analysis with ArcGIS. The assumption is rice production spatial distribution can be an important review of foods security condition in Bekasi District. This spatial distribution can show the results of rice production in  each  zone  Bekasi  District.  Rice is  one of  main  commodity  in agricultural   sector   that   is   also   the   main   source   of   community’s   needs fulfillment.Based on the distribution of monthly rainfall average in Bekasi, that the wet months occurred in January to April and October to December, while the dry months occurred in May to September. The areas that possess a high rice production is Pebayuran Suc-district, Sukawangi Sub-district and Tambelang Sub-district, low rice production is in Cikarang Utara Sub-district and Cikarang Barat Sub-district which is located in Bekasi Regency. In the management of agriculture, farmers in Bekasi not paying attention of resource management in particular aspects of a sustainable environment with high use of chemical fertilizers and pesticides.It can be seen from rice field’s management system which is carelessly and not notifying environment’s sustainability. It can be showed from a chemical fertilizers utilization that causing a degradation of wetland and rice production years by years.Keywords: spatial analysis, rice production, foods security
