Abstract

Kecamatan Panumbangan merupakan salah satu kecamatan yang berada di Kabupaten Ciamis yang terletak dibagian hulu DAS Citanduy sering menghadapi masalah banjir hampir setiap musim hujan. Banjir inimenyebabkan gangguan terhadap aktivitas masyarakat setempat serta kerugian materi yang cukup besar.Intensitas curah hujan yang tinggi, bertambahnya populasi dan perkembangan kawasan permukimanberkontribusi terhadap menurunnya kemampuan lingkungan untuk menyerap air hujan. Metode yang digunakandalam penelitian ini adalah pemodelan hidrologi dan hidrolika menggunakan perangkat lunak HEC-HMS danHEC-RAS. Hasil analisis HEC-HMS menghasilkan Q2 383.6 m3/s, Q5 2556.9 m3/s, Q10 2942.8 m3/s, Q203289 m3/s, Q25 3396.1 m3/s dan Q50 3709.8 m3/s. Sedangkan hasil analisis HEC-RAS menunjukan terjadiluapan yang mengakibatkan banjir pada Desa Payungagung, Sindangherang, Kertaraharja, Tanjungmulya,Panumbangan dan Medanglayang. Solusi mitigasi banjir yang dapat dilakukan yaitu pembangunan tanggulsepanjang 9.440 m’ dengan ketinggian rata-rata 6,3985 m’ dan dilakukan normalisasi terutama pada daerahrawan banjir yaitu pada STA. 497 s/d STA. 18.920. Adapaun solusi lebih lanjut terkait efektivitas berbagaistrategi mitigasi, yaitu secara struktural (pelebaran sungai, sumur resapan, sudetan dan kolam retensi) dan nonstruktural (pengelolaan tata ruang, sistem peringatan dini, dan edukasi masyarakat mengenai mitigasi banjir).

Abstract

The Government of Purwakarta Regency seeks to improve access to safe drinking water; however, by 2024, coverage has only reached 64%, still below the 81% target. This study aims to analyze the effectiveness of community-based Drinking Water Supply System (SPAM) management funded through the Special Allocation Fund (DAK) in three villages: Cipicung, Pasirangin, and Pusakamulya. The evaluation refers to five aspects based on Minister of Public Works and Housing Regulation No. 27 of 2016, namely technical, institutional, financial, social, and environmental aspects. The research method combined analysis of existing conditions and stakeholder perceptions. Primary data were collected through surveys and structured interviews with 129 respondents, while secondary data were obtained from relevant regulations. Data analysis employed the Relative Importance Index (RII) and Confidence Interval (CI). The results indicate that water quality is the most influential factor in determining the effectiveness of SPAM management. Cipicung and Pasirangin villages have successfully implemented all aspects, as reflected in good water quality, strong institutional arrangements, and high community participation. Meanwhile, Pusakamulya village faces challenges in the environmental aspect, particularly in water source protection, which affects water availability. The management model applied in Cipicung and Pasirangin can serve as a reference for other areas, with recommendations focusing on infrastructure improvement and strengthening water source protection
