Abstract

The purpose of this research is to model or describe the distribution of material flow eruption and to know the zoning vulnerable to the disaster of Mount Ungaran if one day there is a volcanic disaster. The method used to model the flow of eruption material is by using Monte Carlo methods of numerical simulation with the assumption that the topography determines the course of the flow. Determination of zoning of disaster prone areas is done by using overlay technique of eruption material flow aspect, land use condition aspect, morphology aspect, and sensitivity aspect to hazard represented by weight value. The result of this research is to produce the eruption material flow model at three different location points, the point is based on the chance of eruption activity. At the first point the area of eruption flow is 3.91𝑘𝑚2, the second point is 1.25𝑘𝑚2, and the third point is 2.51𝑘𝑚2. Zoning of disaster prone areas produces disaster-prone class which is divided into very low, low, medium, and high class. At all three locations the eruption shows that the high disaster-prone zoning class has the smallest area compared to the extent of other disaster-prone zoning classes.

Abstract

The location of health facilities and infrastructure should have a high degree of accessibility. The area of health care services will be greatly influenced by the level of accessibility. The location of facilities and health infrastructure that is easy to reach in terms of transportation, of course, has a special attraction for the community to visit it. This has resulted in the health service area exceeding the work area determined by the local government. Data analysis techniques used nearest neighbor analysis, accessibility index analysis and serviceability analysis. The results of this study indicate that 1) Distribution pattern of health center at sub-district level and doctors practice classified dispersed (dispered pattern), the pattern of distribution of the hospital classified unequally spread (random pattern) and pattern of distribution pharmacy in clustered. 2) The accessibility level in terms of distance to reach the location of health facility and infrastructure in Tegal Regency is mostly well classified / easy to reach. Its just that there are still some roads that still use paving, and in some districts are also still there are hollow road conditions. 3) The number of health facilities that have been fulfilled is the number of health center at sub-district level, and the hospital. The number of health facilities that have not been fulfilled is the number of community health sub-center, practice doctors and pharmacies.
