Abstract
Ketersediaan air yang berkualitas dan memadai adalah aspek krusial dalam menjaga kelangsungan kehidupan dan keberlanjutan lingkungan. Ketidakcukupan sistem distribusi air minum untuk memenuhi permintaan dan tekanan biasanya
disebabkan oleh peningkatan populasi dan urbanisasi cepat, tingginya tingkat kebocoran dalam sistem distribusi. Salah satu cabang Perumda Air Minum Tirta Lestari yaitu Cabang IV memiliki peran krusial dalam menyediakan pasokan air minum bagi tiga kecamatan yang dilayaninya. Peningkatan jumlah penduduk, kebocoran pipa, gangguan pipa akibat tekanan dan aliran yang tinggi seringkali menyebabkan pecahnya pipa, serta biaya operasional yang tinggi sehingga menjadi focus utama dalam perencanaan perluasan cakupan pelayanan. Kapasitas eksisting yang dihasilkan dari 3 lokasi dengan 9 unit produksi yaitu 106 L/detik dengan jumlah pelanggan 10.535 SR dan tingkat kehilangan air yang mencapai 32% pada
tahun 2023.
Penelitian ini bertujuan untuk melakukan optimasi dan pengembangkan jaringan distribusi air minum di Cabang IV Perumda Air Minum Tirta Lestari sebagai respons terhadap tantangan yang dihadapi agar mampu memenuhi kriteria pelayanan air minum yaitu kuantitas, kualitas, kontinuitas, dan keterjangkauan. Evaluasi dilakukan dengan analisis teknis, finansial dan kelembagaan. Analisis teknis dilakukan berdasarkan data yang didapatkan di lapangan dan analisis simulasi sistem distribusi menggunakan Epanet 2.2.
Hasil analisis jaringan distribusi di Cabang IV Perumda Air Minum Tirta Lestari menunjukkan bahwa jaringan UPK Palang dan UPK Semanding memenuhi standar tekanan dan headloss, sementara UPK Grabagan masih memiliki tekanan rendah di beberapa titik karena elevasi bervariasi. Kecepatan aliran yang rendah di beberapa pipa dimaksudkan untuk mendukung pengembangan pelanggan. Pengembangan sistem distribusi direncanakan dalam dua tahap (2024-2028 dan 2029-2033) dengan kapasitas air yang masih mencukupi selama 10 tahun ke depan untuk UPK Palang dan UPK Semanding, sedangkan UPK Grabagan membutuhkan tambahan sumur baru pada tahun 2031. Analisis finansial menunjukkan NPV positif (Rp 3.844.979.938,41), IRR 20%, dan BCR >1. Sehingga pengembangan ini layak dilaksanakan untuk mencapai tujuan utama, yaitu meningkatkan ketersediaan air, memperluas pelayanan di wilayah Cabang IV Perumda Air Minum Tirta Lestari, serta mengoptimalkan sistem distribusi yang ada.

The availability of quality and adequate water is a crucial aspect in maintaining the continuity of life and environmental sustainability. The inadequacy of the drinking water distribution system to meet demand and pressure is usually caused by population increase and rapid urbanization, high leakage rate in the distribution system. One of the branches of Perumda Air Minum Tirta Lestari, namely Branch IV, has a crucial role in providing drinking water supply for the three sub-districts it serves. Population increases, pipe leakage, pipe disruption due to high pressure and flow often causing pipe rupture, and high operational costs are the main focus in planning for service coverage expansion. The existing capacity generated from 3 locations with 9 production units is 106 L/sec with a total of 10,535 SR customers and a water loss rate that reached 32% in 2023.
This study aims to optimize and develop the drinking water distribution network in Branch IV of Perumda Air Minum Tirta Lestari in response to the challenges faced in order to meet the criteria of drinking water services, namely quantity, quality, continuity, and affordability. The evaluation was conducted using technical, financial and institutional analysis. Technical analysis was carried out based on data obtained in the field and distribution system simulation analysis using Epanet 2.2.
The results of the distribution network analysis in Branch IV of Perumda Air Minum Tirta Lestari show that the UPK Palang and UPK Semanding networks meet the pressure and headloss standards, while UPK Grabagan still has low pressure at some points due to varying elevations. The low flow velocity in some pipes is intended to support customer development. Distribution system development is planned in two stages (2024-2028 and 2029-2033) with sufficient water capacity for the next 10 years for UPK Palang and UPK Semanding, while UPK Grabagan requires additional new wells in 2031. The financial analysis showed a positive NPV (IDR 3.844.979.938,41), IRR of 20%, and BCR >1. Therefore, this development is feasible to achieve the main objectives, namely increasing water availability, expanding services in the area of Branch IV of Perumda Air Minum Tirta Lestari, and optimizing the existing distribution system.
