Abstract

Kinerja dari suatu PDAM merepsentasikan tingkat kualitas penyelenggaraan air minum pada suatu daerah. Permasalahan yang sering dialami oleh PDAM adalah tingginya angka kehilangan air. Perumda Giri Tirta Kabupaten Gresik dengan tingkat kehilangan air sebesar 43,1% pada triwulan I tahun 2023, sedangkan batas maksimal kehilangan air sebesar 20%. Oleh karena itu, tingkat kehilangan air di Perumda Giri Tirta Kabupaten Gresik belum sesuai standar yang berlaku. Tujuan dari penelitian ini yaitu: (1) Mengkaji kondisi eksisting kehilangan air di Perumda Giri Tirta Kabupaten Gresik Cabang Kota, (2) Menganalisis strategi yang tepat dalam penurunan kehilangan air di Perumda Giri Tirta Kabupaten Gresik Cabang Kota dan (3) Menghitung biaya penurunan kehilangan air di Perumda Giri Tirta Kabupaten Gresik Cabang Kota. Penelitian ini diawali dengan melakukan studi literatur mengenai kehilangan air, kemudian dilakukan pengumpulan data primer dan data sekunder di Perumda Giri Tirta Kabupaten Gresik Cabang Kota. Data yang telah didapatkan digunakan untuk menyusun neraca air dengan software WB EasyCalc. Kemudian dilakukan analisis kehilangan air tiap komponen neraca air, analisis kualitas air minum, analisis hidrolika dari jaringan distribusi. Dari analisis tersebut dapat ditentukan strategi penurunan kehilangan air di Perumda Giri Tirta Kabupaten Gresik Cabang Kota. Kehilangan air disebabkan oleh kehilangan air fisik dan non fisik, dimana total volume kehilangan air sebesar 15.390.904 m3/tahun. Dimana kehilangan air tertinggi disebabkan oleh kehilangan air fisik dengan volume kehilangan sebesar 14.312.402 m3/tahun, sedangkan volume kehilangan air non fisik sebesar 1.078.502 m3/tahun. Rencana strategi yang dapat dilakukan oleh Perumda Giri Tirta Kabupaten Gresik Cabang Kota dalam mengurangi kehilangan air yang terjadi yaitu pembentukan DMA dan penggantian meter pelanggan. Biaya yang diperlukan untuk pengendalian kehilangan air sebesar Rp 8.008.123.000

The performance of a PDAM represents the level of quality of drinking water management in an area. The problem often experienced by PDAMs is the high rate of water loss. Perumda Giri Tirta Gresik Regency with a water loss rate of 43.1% in the first quarter of 2023, while the maximum water loss limit is 20%. Therefore, the level of water loss in Perumda Giri Tirta, Gresik Regency is not yet in accordance with applicable standards. The objectives of this research are: (1) Assessing the existing conditions of water loss at Perumda Giri Tirta, Gresik Regency, City Branch, (2) Analyzing appropriate strategies for reducing water loss at Perumda Giri Tirta, Gresik Regency, City Branch, and (3) Calculating the cost of reducing losses. water at Perumda Giri Tirta, Gresik Regency, City Branch. This research began by conducting a literature study regarding water loss, then collecting primary and secondary data at Perumda Giri Tirta, Gresik Regency, City Branch. The data that has been obtained is used to compile a water balance using WB EasyCalc software. Then an analysis of water loss for each water balance component, analysis of drinking water quality, hydraulic analysis of the distribution network is carried out. From this analysis, a strategy for reducing water loss in Perumda Giri Tirta, Gresik Regency, City Branch can be determined. Water loss is caused by physical and non-physical water loss, where the total volume of water loss is 15,390,904 m3/year. Where the highest water loss is caused by physical water loss with a loss volume of 14,312,402 m3/year, while the volume of non-physical water loss is 1,078,502 m3/year. The strategic plan that can be carried out by Perumda Giri Tirta Gresik Regency City Branch to reduce water losses that occur is the establishment of a DMA and replacing customer meters. The costs required to control water loss are IDR 8,008,123,000.
