Abstract

Perumda Air Minum Sumber Sejahtera pada tahun 2022 memiliki tingkat NRW sebesar 37,36%, masih jauh diatas Tingkat Kehilangan air yang diijinkan yaitu 18 – 20 % dan Target RPJMN (2020-2024) yaitu 25%. Tingginya nilai NRW saat ini belum dapat diturunkan dikarenakan belum ada program penanganan NRW seperti pembentukan District Meter Area (DMA) ataupun pengendalian kebocoran aktif di Perumda Air Minum Sumber Sejahtera. Maka perlu disusun strategi pengendalian Non-Revenue Water di P Perumda Air Minum Sumber Sejahtera agar tingkat kehilangan air yang ada dapat diturunkan. Kajian dilakukan dengan melakukan analisis terkait kondisi eksisting pengendalian NRW di Perumda Air Minum Sumber. Analisis tersebut meliputi nilai NRW Eksisting, Suplai air dan pemakaian air pelanggan, serta data pompa dan jaringan distribusi air minum SPAM Kota Bangkalan. Selanjutnya ditentukan prioritas strategi pengendalian NRW dan wilayah pelayanan pada SPAM Kota Bangkalan. Strategi pengendalian NRW akan dianalisis dari aspek teknik, keuangan, dan kelembagaannya. Strategi pengendalian NRW pada wilayah pelayanan prioritas direncanakan melalui perencanaan District Meter Area (DMA). Analisis hidrolis pada wilayah pelayanan prioritas dibuat dua alternative, yaitu dengan menggunakan pemasangan pipa baru pada Alternatif 1 dan pemasangan pompa booster pada Alternatif 2. Kedua alternatif penanganan memiliki tekanan pada titik kritis mendekati 5,00 m dengan penurunan nilai NRW masing-masing alternatif menjadi 30,76% dan 31,48%. Berdasarkan penurunan yang terbesar, dipilih desain alternatif 1 menjadi desain yang direkomendasikan dan dilanjutkan ditinjau aspek keuangan dan kelembagaannya. Pada aspek keuangan, desain pengendalian kehilangan air yang direkomendasikan dengan nilai investasi Rp 370.334.843,58 layak secara finansial setelah dianalisis nilai BCR, PP, serta NPV. Sedangkan ditinjau dari aspek kelembagaan, strategi yang paling tepat pada Perumda Air Minum Sumber Sejahtera adalah dengan strategi memaksimalkan keuntungan dengan kekuatan yang ada pada perusahaan

Perumda Sumber Sejahtera Drinking Water in 2022 has an NRW level of 37.36%, still far above the permitted water loss level of 18 – 20% and the RPJMN target (2020-2024) of 25%. The high NRW value cannot currently be reduced because there is no NRW management program such as the establishment of a District Meter Area (DMA) or active leak control at the Sumber Sejahtera Drinking Water Company. So it is necessary to develop a strategy to control Non-Revenue Water at Perumda Air Minum Sumber Sejahtera so that the level of existing water loss can be reduced. The study was carried out by conducting an analysis regarding the existing conditions of NRW control at Perumda Air Minum Sumber. This analysis includes the Existing NRW value, water supply and customer water usage, as well as data on pumps and the Bangkalan City SPAM drinking water distribution network. Next, the priority strategies for controlling NRW and service areas at Bangkalan City SPAM are determined. NRW control strategies will be analyzed from technical, financial and institutional aspects. The NRW control strategy in priority service areas is planned through District Meter Area (DMA) planning. Hydraulic analysis in priority service areas created two alternatives, namely by using the installation of new pipes in Alternative 1 and the installation of booster pumps in Alternative 2. Both treatment alternatives have a pressure at the critical point approaching 5.00 m with a decrease in the NRW value of each alternative to 30 .76% and 31.48%. Based on the largest decrease, alternative design 1 was selected as the recommended design and continued to review its financial and institutional aspects. In the financial aspect, the recommended water loss control design with an investment value of IDR 370,334,843.58 is financially feasible after analyzing the BCR, PP and NPV values. Meanwhile, from an institutional aspect, the most appropriate strategy for Perumda Air Minum Sumber Sejahtera is the strategy of maximizing profits using the company's existing strengths
