Abstract

 Perumdam Tirta Tarum Karawang Regency, an agency providing drinking water services with service coverage for a population of 22.58%, has an NRW (Non-Revenue Water) level of 32.16%  and the NRW level for the Kotabaru Branch service area is 29.21%  in 2022. Analysis of the implementation of SOPs (standard operating procedures) in NRW control needs to be carried out so that monitoring of quality consistency can be carried out and makes it easier to evaluate the implementation of NRW control activities that have been carried out. This research uses quantitative and qualitative methods by conducting observations and interviews with related parties that focus on 7 (seven) indicators in the SOP: efficiency, consistency, error minimization, problem-solving, workforce protection, work maps, and defense boundaries. The results of the analysis carried out on the implementation of SOPs at Perumdam Tirta Tarum Karawang Regency related to 7 (seven) SOP indicators showed that the effectiveness of the performance of 5 (five) SOP indicators was good, while 2 (two) SOP indicators were still in the sufficient category. Overall, the implementation of existing SOPs is easy to understand and has been implemented well. However, if you look at the details of this reference SOP, it is still passive NRW control. The implementation of the SOP can only be carried out after receiving reports and complaints from the public. Keywords: SOP (standard operating procedures), NRW, Perumdam Tirta Tarum. Abstrak Perumdam Tirta Tarum Kabupaten Karawang sebagai instansi penyedia jasa air minum dengan cakupan pelayanan terhadap jumlah penduduk sebesar 22,58 % memiliki tingkat NRW (Non Revenue Water) sebesar 32,16 % dan tingkat NRW untuk wilayah pelayanan Cabang Kotabaru sebesar 29,21 % pada Tahun 2022 Analisis penerapan SOP (standar operasional prosedur) dalam pengendalian NRW perlu dilakukan agar pemantauan terhadap kosistensi kualitas dapat dilakukan dan memberikan kemudahan dalam mengevaluasi pelaksanaan kegiatan pengendalian NRW yang telah dilakukan. Penelitian ini menggunakan metode kuantitatif dan kualitatif dengan melakukan observasi dan wawancara dengan pihak-pihak terkait yang difokuskan pada 7 (tujuh) indikator dalam SOP yaitu efisiensi, kosistensi, minimalisasi kesalahan, penyelesaian masalah, perlidungan tenaga kerja, peta kerja, dan batasan pertahanan . Hasil analisis yang  dilakukan terhadap penerapan SOP pada Perumdam Tirta Tarum Kabupaten Karawang dikaitkan dengan 7 (tujuh) indikator SOP didapatkan hasil bahwa penerapan 5 (lima) indikator SOP secara efektifitas sudah baik., sedangkan 2 (dua) indikator SOP masih masuk dalam kategori cukup. Sehingga secara keseluruhan penerapan SOP yang sudah ada mudah dipahami dan sudah diterapkan dengan baik, namun jika dilihat dari detail SOP acuan ini masih bersifat pengendalian NRW secara pasif, penerapan SOP baru dapat dilakukan setelah mendapat pelaporan, aduan dari masyarakat.

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.

Abstract

SPAM of Palangka Raya City has a distribution unit which is powered by six pumps but only two pumps are functioning due to frequent damage to the pumps. The pumps that function is Pump III and Pump V. This research aims to evaluate pump efficiency and specific energy consumption (SEC) so that technical recommendations for optimizing existing distribution pumps are known. Pump III is installed with a VSD with a SEC value of 0.14 KWh/m3 with a pump efficiency of 70.41% so it does not require minor or major repairs but requires a new backup pump because it works 24 hours while Pump V has a SEC of 0.27 KWh/m3 with a pump efficiency of only 36.97% which requires a new pump replacement. Both pumps experienced the same problem, namely V-Unbalanced which reached 2.72-2.73%, causing a decrease in motor performance which could cause damage to the pump components and VSD, so a capacitor bank and voltage stabilizer were needed. The evaluation of energy loss in the distribution network was carried out by increasing the diameter of 57 pipe segments to reduce headloss to less than 10 m/km.
