Analisis Keberlanjutan Pemanfaatan Program Penyediaan Air Minum dan Sanitasi Berbasis Masyarakat di Desa Binjai Baru Kecamatan Datuk Tanah Datar Kabupaten Batu Bara

Abstract

The Community-Based Drinking Water and Sanitation Supply Program (PAMSIMAS) is one of the government’s efforts to improve access to clean water and sanitation in rural areas. However, the sustainability of drinking water infrastructure utilization continues to face various challenges, including technical, institutional, social, economic, and environmental aspects. This study aims to: (1) identify the factors influencing the sustainability of the PAMSIMAS program; (2) evaluate the existing condition of sustainability sub-criteria based on community perceptions; and (3) determine the priority of sustainability criteria and sub-criteria using the Analytical Hierarchy Process (AHP) method. The research was conducted in Binjai Baru Village, Datuk Tanah Datar District, Batu Bara Regency, using a quantitative approach through questionnaire distribution to the community and interviews with ten expert respondents. The analysis of community perception data shows that most sustainability sub-criteria are categorized as “influential,” with average scores ranging from 3.70 to 4.23. The sub-criteria of operational reliability of the water production system and quality of the surrounding water environment received the highest scores and were classified as “very influential.” The AHP results indicate that the social aspect is the most dominant criterion (priority weight 0.2401), followed by economic (0.2185), environmental (0.2058), technological (0.1844), and institutional (0.1512) aspects. The highest-weighted sub-criteria are community participation (0.1460), water tariff system (0.1231), environmental protection (0.1125), water quality (0.1087), and institutional role (0.0972). The consistency analysis produced a Consistency Ratio (CR) of 0.0841, indicating an acceptable level of consistency in the expert assessments. Based on the final calculation, Location L1 was identified as the most sustainable alternative with a priority weight of 0.602 compared to L2 (0.396). These findings demonstrate that AHP can be effectively utilized to establish strategic sustainability priorities for community-based water supply programs. Strategic recommendations are directed at strengthening social capacity, improving the financial contribution system, and ensuring institutional and technical support in a sustainable manner.
