GIS Application for Health Facility Coverage Mapping in Temanggung Regency, Central Java Province

Adequate health facilities have become one of the interesting issues to be discussed since this pandemic situation. Availability and accessibility of health facilities are the vital aspects that should be accomplished by both local and central government. Nevertheless, some population especially those living in rural areas have some difficulties in reaching these facilities due to the inequality condition within regions. This study aims to analyze the coverage of health facilities in Temanggung Regency, Central Java province and cluster its subdistricts according to their condition in accessing these facilities. The analysis is limited to public health facility (PUSKESMAS) and hospital levels. Both statistical and spatial data were processed using the GIS network analysis approach in producing the coverage number of each health facility and they were compared to the applied standard range of service and threshold. Then, a hierarchy is created using the weighted centrality index approach to represent disparities among subdistricts in Temanggung Regency regarding the availability and its coverage to health facilities. The results show that there is an inequality condition on health facilities coverage between central and peripheral areas within this regency, both at the public health facility level and hospital level. Several population in several districts, mostly residing in outer areas, are not covered by both public health facility and hospital. On the other hand, people in the capital and its surrounding subdistricts have better access to these facilities. Several factors are identified in producing this inequality, such as spatial distribution of housing areas, spatial allocation of health facilities, road network, and topographic condition. The topographic condition in some uncovered areas, which is relatively hilly and has steep slope, causes limited access to the road network and less coverage of health facilities.

Penggunaan Data DEM SRTM untuk Pemetaan Daerah Rawan Banjir di Kecamatan Lhoksukon Kabupaten Aceh Utara

Abstrak. Banjir merupakan masalah umum di sebagian daerah yang ada di Indonesia, terutama pada daerah yang memiliki topografi yang rendah di bagian hilir sungai. Penelitian ini bertujuan untuk melihat daerah yang sering dilanda banjir dengan hubungan peta daerah rawan banjir di Kecamatan Lhoksukon Kabupaten Aceh Utara. Kondisi topografi Kecamatan Lhoksukon dengan kelandaian yang curam dibagian hulu namun landai dibagian hilir, sehingga keadaan topografi ini dapat menyebabkan aliran air mengalir dengan kecepatan yang rendah pada daerah hilir. Keadaan topografi tersebut menggambarkan bahwa secara fisik Kecamatan Lhoksukon merupakan daerah yang rawan terhadap banjir. Berdasarkan hasil analisis kerawanan banjir di Kecamatan Lhoksukon dibagi 3 kelas yaitu kelas kerawanan sangat rawan banjir diperoleh 642,30 hektar, kelas rawan banjir 11.544,70 hektar dan kelas tidak rawan banjir seluas 1.542,57 hektar.Use Of Demographic Data For Mapping Flood-Prone Areas in Lhoksukon Sub-District, North Aceh RegencyAbstract. Flooding is a common problem in some regions in Indonesia, especially in areas that have low topography in the downstream river. This study aims to look at areas that are often hit by floods with the flood-prone areas in Lhoksukon Sub District, North Aceh District. The topographic condition of Lhoksukon District is which steep slope in upstream but sloping in the downstream, so that topography can caused run off at a low speed in the downstream area. The topographical situation illustrates that physically Lhoksukon District is an area prone to flooding. Based on the results of the analysis of flood vulnerability in Lhoksukon Sub District divided into 3 classes: 642.30 ha of highly hazard-prone, 11,544.70 ha of flood-prone and 1,542.57 ha of non-flood-prone.

Analysis of Land Cover Changing and Vegetation Index at Kuranji Watershed in Padang, West Sumatera, Indonesia

Various activities around Kuranji watershed included the land conversioncan be impacted to topographic condition and also contributed to altering the vegetation density. Remote sensing technology is an effective methodfor land cover mapping. The objectives of the present study were to analyze the changing of land cover and classifying the vegetation density index in the upstream Kuranji Watershed. This study was conducted at Kuranji Watershed in Padang, West Sumatera Province. Two Landsat images representing the changing of the watershed area during 2017 and 2018 as well as obtaining the classification of vegetation density during corresponding years.Landsat 8 OLI images were classified using a supervised classification technique, then computed the vegetation index using the Normalized Difference Vegetation Index (NDVI). The result showed that the extension of forest area, settlement area and paddy field (283.92; 35.06; and 27 Ha, respectively) and decline of mix dryland agriculture, shrub and garden area (93.68; 277.43; and 190.95 Ha respectively). Decreasing of dense vegetation found at lower dense class (6.47 Ha) and highest dense class (5535.35 Ha). Therefore, the increasing area found at the cloud, dense and higher dense class (93.17; 5525.1; and 109.94 Ha, respectively). So, it is highlighted that changing land cover and vegetation index happen during the only one-year period.

Analisis Kapasitas Penampang Sungai Batang Mahat Terhadap Besaran Debit Banjir Menggunakan Pendekatan Model Matematik

Batang Mahat watershed has a total area of 772.87 km2 with a total length of the main rivers around 44.06 km. With the topographic condition on the upstream side was a mountainous terrain and steep slope relatively into downstream. The problem was can be classified as river siltation, narrowing of the river, and riverbank erosion that has caused flood and threaten a public facilities. Numerical simulations using the application of the HEC RAS model were conducted to determine the capability of the river storage capacity into various discharge values. The results of the analysis show that with the discharge condition Q2 there has been flood caused by the high surface elevation of water that was overtopping of the left and right embankments elevation at the upstream and midstream areas. The water surface elevation will increase with the increasing of flood discharge. River normalization efforts with additional depth and widening of river channel were recommended.
