Abstract

Wai U Village has a problem with the limited capacity of the village's clean water supply system. This community service activity aims to retrofit the existing clean water supply system, which previously experienced technical problems, and to increase the capacity of the existing system. The implementation method consists of pre-site visit interviews, field surveys, geoelectric surveys to determine aquifer potential, and water quality laboratory tests for drinking water standards. The results of the geoelectric data analysis show that the potential aquifer was located at 30m below the surface. The water quality test results show that the groundwater quality generally meets the class-1 water quality standards for drinking water. Field survey activities were followed by the construction of groundwater wells, water towers, water reservoirs, pumps, and a series of pipes connecting the new water sources to the existing pipe distribution network of Wai U Village. The final result of this activity was the improvement of the clean water supply capacity in Wai U Village, which was able to connect houses that previously depended on water sources from dug wells. There are 69 houses in the Wai U Village. Before experiencing technical problems, the existing water supply system (Pamsimas) in Wai U Village was connected to 38 houses (55%). The construction of new water supply infrastructure was connected to the remaining 31 houses (45%); thus, this activity has succeeded in increasing clean water network connections by almost 100% in Wai U Village. However, several house connections require rehabilitation. This activity is expected to be one of the real contributions of universities to achieving water, food, and energy security in Wai U Village, which is categorized as a 3T region.

Abstract

Sungai Citarum ditetapkan sebagai wilayah sungai strategis nasional berdasarkan Keputusan Presiden Republik Indonesia Nomor 12 Tahun 2012 dengan kode WS : 02.06.A3 yang berada di wilayah admiistrasi Provinsi Jawa Barat. Bagian dari sungai Citarum yaitu Citarum Hilir dimulai dari pembuangan Waduk Jatiluhur, Purwakarta hingga bermuara di Muara Gembong, Kab. Bekasi. Permasalahan daya rusak air di sunga Citarum Hilir cukup tinggi dikarenakan salah satu anak sungai yaitu sungai Cibeet dengan luas DAS 915 km2 selalu berpotensi untuk mengirimkan debit yang besar saat intensitas hujan tinggi. Pada penelitian ini batasan pemodelan dimulai dari pertemuan Sungai Citarum Hilir dengan sungai Cibeet hingga bagian muara. Dengan input debit di bagian hulu yaitu debit operasional Bendung Walahar serta DAS Cibeet. Selain itu terdapat input debit lateral inflow atau aliran sungai-sungai kecil di sepanjang sungai Citarum dan memperhitungkan kondisi pasang surut dengan menggunakan tinggi muka air rata-rata. Dengan tujuan menganalisis besar banjir secara 1D menggunakan perangkat lunak HEC-RAS yang terjadi akibat luapan debit sungai Cibeet selain itu memberikan alternatif pengendalian banjir di kawasan tersebut. Hasil dari penelitian ini memberikan upaya pengendalian banjir berupa normalisasi dan pembangunan kolam retensi yang menyisakan limpasan sebesar 28,28 %.
