Abstract
The COVID-19 pandemic has made many people aware of the real condition of the national health system. The efforts to handle the pandemic occurred simultaneously throughout the territory of Indonesia that had never been thought of before. The Ministry of Health through the Health offices is working hard to tackle the Covid 19 outbreak. Public Health Centers are the technical implementing units in each region that have duties in carrying out promotive, preventive, curative, and rehabilitative efforts. Problems arise when the service standards of the public health center are not the same in all regions of Indonesia. On the other hand, the reachability of health facilities is still a problem in some places. In this study, we are interested in mapping the pattern and reachability of level one health facilities in Nguter Sub-District, Sukoharjo Regency, Central Java, Indonesia using a geographic information system (GIS). This study would be spatially analysed by using nearest neighbour method in ArcGIS. The evaluation of reachability was done by using a minimum service standard by the Decree of the Minister of Settlement and Regional Infrastructure No. 534/KPTS/M/2001. The results showed that the mapped health facilities in Nguter Sub-District were 2 Public Health Centers and 3 Sub-Public Health Centers. Based on the analysis of the nearest neighbors, the public health center in the Nguter Sub-District show a dispersed pattern. From the results of buffering, it is known that almost the entire area of Nguter Sub-District has covered by the Public Health Centers and Sub-Public health centers.
