Evaluation of Mapping Program Outcomes Achievements of the Clean Water and Proper Sanitation Programme Utilizing Geographic Information Systems

The UPTD Puskesmas Lunto Working Area has a lower percentage of access to clean water and sanitation than other places in Sawahlunto City in 2023, making it an environmental health issue. This study employed GIS to spatially analyze environmental health problems to determine the distribution and position of research objects to evaluate community access to clean water and sanitation. The project aimed to map clean water sources and sanitation in the Working Area of UPTD Puskesmas Lunto, Kecamatan Lembah Segar, Kota Sawahlunto in 2023. Mixed-method research analyzes primary and secondary data. In 2023, 1711 data on household heads' use of clean water sources and proper sanitation were collected from field mapping, RBI maps, and high-resolution Google Earth images for mapmaking and spatial analysis using the overlay method. The study found that clean water and sanitation access varied by location. East Lunto village has the most clean water (82.00%), while Kubang Tangah has the least (61.24%). West Lunto village has the highest proportion of improved sanitation (96.40%), while Kubang Tangah village has the lowest (88.95%). The research locations' geography and population distribution hindered clean water availability and access, preventing clean water supply system integration. Thus, the local government must create protected springs and hygienic latrines for families who have them and a program to deliver clean PDAM water to the community in the UPTD Puskesmas Lunto operating area. Continuous health education is needed to change river defecators' behavior.
