Abstract

PDAM Bandarmasih Kota Banjarmasin telah menerapkan upaya pengendalian kehilangan air dengan penerapan District Metered Area (DMA). Namun, tingkat kehilangan air yang terjadi di wilayah 1 masih sebesar 37,49% (Desember 2020). Keterbatasan sumber daya menyebabkan PDAM tidak dapat melaksanakan kegiatan penurunan kehilangan air pada seluruh DMA yang telah dibentuk. Oleh sebab itu, diperlukan sebuah proses pemilihan DMA yang tepat untuk dijadikan prioritas dalam melakukan upaya penurunan kehilangan air yang terjadi. Penentuan DMA prioritas dilakukan dengan menggunakan metode AHP (Analytical Hierarchy Process) untuk menentukan kriteria pemilihan dan pemeringkatan DMA yang memiliki kesiapan untuk pelaksanaan penurunan kehilangan air. Lima DMA yang memiliki nilai tertinggi merupakan DMA Prioritas yang terpilih. Berdasarkan hasil analisis AHP, diperoleh 5 (lima) kriteria yang akan digunakan dalam proses pemeringkatan DMA, yaitu tekanan, kehilangan air, panjang pipa, kelompok pelanggan, dan luas wilayah. Hasil pemeringkatan DMA diperoleh 5 (lima) DMA prioritas untuk penurunan kehilangan air dengan urutan sebagai berikut: (i) DMA 420; (ii) DMA 130; (iii) DMA 404; (iv) DMA 412; dan (v) DMA 410. Total biaya capex dan opex pelaksanaan penurunan kehilangan air di 5 (lima) DMA prioritas sebesar Rp 466.834.488, dengan rincian kebutuhan biaya untuk DMA 420 sebesar Rp 118.764.926; DMA 130 sebesar Rp 36.152.817; DMA 404 sebesar Rp 70.475.045; DMA 412 sebesar Rp 90.425.034, dan DMA 412 sebesar Rp 151.016.665.

Abstract

NRW is still a problem for PDAMs in Indonesia in providing drinking water for the community. This can be seen from the national average NRW level in 2021, which was 33.72% (higher than the RPJMN target of 30%). The ATR reduction strategy can be carried out correctly if the indicators or components are accurately measured. The problem is that many PDAMs need help to understand the definition or calculate ATR components according to international standards with high confidence. In this research, a water balance was prepared using WB-EasyCalc to determine the value of each ATR component with a 95% confidence level, potential loss of income, and ILI value. The results of the water balance analysis show that the ATR level at Perumda Air Minum Palangka Raya in May 2023 was 51.84%. This percentage comprises 2.19% non-revenue official consumption and 49.64% water loss. If the NRW percentage is not reduced, the potential loss of income is estimated at IDR 15,395,984,969/year. The component that causes the most water loss is physical water loss, which reaches 42.67%. The physical water loss performance indicator (ILI) has a value of 23, which is included in performance category D (extraordinary waste of resources occurs, and leak reduction programs must be prioritized). Recommendations that can be given are related to the active leak detection and pressure management.
