Optimalisasi Jaringan Distribusi Air Minum melalui Perencanaan District Metered Area (DMA) Yang Berkelanjutan di Kecamatan Doloksanggul Kabupaten Humbang Hasundutan

Abstract

Drinking water is one of the basic human needs and is essential for improving the quality of human life and economic growth in a region. The provision of drinking water through the piped water supply network in Doloksanggul District currently has a service coverage of 25.61% and a loss rate of 32%, indicating that the drinking water distribution system is still not optimal. The purpose of this study is to analyze the distribution pattern of drinking water needs and the zoning pattern of the drinking water distribution system according to regional characteristics and the rules of the district metered area (DMA) in Doloksanggul District. The DMA concept is a strategy for managing water loss, especially physical water loss, namely by dividing an open water supply network into isolated zones with smaller water meters. In this study, a study was conducted on the formation of a sustainable DMA until 2044 using a GISbased spatial analysis method. The analysis in this study starts from population projections, land cover classification, predictions of land cover changes to predictions of the distribution of drinking water needs using a grid system of various scales. From the research results, it was found that the density of house connections is on the southeast - northwest axis with Pasar Doloksanggul Village as the median center, where in 2024 it consists of 12 zones, in 2029 it consists of 13 zones, in 2034 it consists of 14 zones, in 2039 it consists of 16 zones and in 2044 it consists of 20 zones.
