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

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

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

This study is related to the implementation that can be done for disaster education materials with demonstration methods in extracurricular activities in high school. The purpose of this study was to determine the forms of implementation of demonstration methods for disaster education in extracurricular activities at the high school level so as to provide learning and capacity building of students against disaster risk. The research method used is descriptive quantitative data collection in the form of literature. The results showed that the implementation of disaster education in extracurricular activities using the demonstration method requires several stages, namely the preparation, implementation, and evaluation. There are two extracurricular activities in high school that can be integrated with disaster education using demonstration methods, namely Scouts and PMR. Scout activities can demonstrate disaster education about mitigation efforts that must be done, as well as about the path and evacuation efforts in the event of a disaster, the manufacture of stretchers for the evacuation of disaster victims, helping victims who are at high altitudes and at low bases, such as valleys by using rope knots, and the skills of erecting emergency tents. Meanwhile, PMR activities that can demonstrate more disaster education about medical treatment to disaster victims.
