Abstract

Perumda Sumber Sejahtera Kabupaten Bangkalan khususnya di SPAM Kota Bangkalan menggunakan sistem pemompaan dalam mendistribusikan air ke wilayah layanannya. Hal ini menjadi permasalahan yang dihadapi, dikarenakan konsumsi energi yang cukup besar dalam operasional pompa. Berdasarkan Buku Kinerja BUMD Air Minum Tahun 2022, biaya energi Perumda Sumber Sejahtera mencapai Rp.890/m3 (biaya energi rata-rata nasional Rp.356,34/m3), Sehingga diperlukannya evaluasi serta pengoptimalan dalam konsumsi energi khususnya di SPAM Kota Bangkalan. Penelitian ini menggunakan metode deskriptif dengan pendekatan survey dan studi kasus. Analisis kondisi eksisting berupa evaluasi kinerja pompa distribusi, kualitas daya, serta jaringan distribusi sehingga dapat diidentifikasi penyebab tingginya biaya energi pada SPAM Kota Bangkalan. Selain itu rekomendasi perbaikan akan dianalisis potensi penghematan yang dihasilkan serta nilai investasinya akan dinilai kelayakannya menggunakan analisis BCR, PP, NPV, dan IRR. Evaluasi aspek kelembagaan menggunakan analisis SWOT dalam merumuskan program penguatan kelembagaan pada Perumda Sumber Sejahtera. Hasil dari penelitian ini didapatkan bahwa biaya energi yang tinggi dapat disebabkan oleh rendahnya nilai efisiensi pada masing-masing pompa distribusi yakni berkisar 35-52% dan nilai SEC berkisar 0,30-0,46 kWh/m3, serta adanya perbedaan tarif di jam-jam tertentu (Waktu Beban Puncak). Dari hasil simulasi dan analisis kondisi eksisting pada wilayah distribusi pompa junok diperlukan optimasi pompa secara penuh guna meningkatan efisiensi pompa, perbaikan jaringan distribusi guna memenuhi kriteria desain dengan mengurangi headloss dan penambahan tekanan menggunakan pompa booster, serta pengaturan pola VSD. Sehingga terdapat penghematan sebesar Rp. 4.258.740 tiap bulannya. Dilihat dari kriteria investasi, rekomendasi yang diberikan dapat dikatakan layak dinilai dengan metode BCR, PP, NPV, serta IRR. Dalam pelaksanaan peningkatan efisiensi energi diperlukan strategis penguatan aspek kelembagaan yakni dengan menciptakan strategi yang meminimalkan kelemahan untuk memanfaatkan peluang.

Perumda Sumber Sejahtera Bangkalan Regency, especially in the Bangkalan City SPAM, uses a pumping system to distribute water to its service area. This is a problem faced, due to the considerable energy consumption in pump operations. Based on the 2022 BUMD Drinking Water Performance Book, Perumda Sumber Sejahtera's energy costs reached Rp.890/m3 (national average energy costs of Rp.356.34/m3), so it is necessary to evaluate and optimize energy consumption, especially in Bangkalan City SPAM. This research uses a descriptive method with a survey and case study approach. Analysis of existing conditions in the form of evaluating the performance of distribution pumps, power quality, and distribution networks so that the causes of high energy costs in Bangkalan City SPAM can be identified. In addition, improvement recommendations will be analyzed for potential savings generated and the investment value will be assessed for feasibility using BCR, PP, NPV, and IRR analysis. Evaluation of institutional aspects using SWOT analysis in formulating institutional strengthening programs at Perumda Sumber Sejahtera. The results of this study found that high energy costs can be caused by the low efficiency value of each distribution pump, which ranges from 35-52% and SEC values ranging from 0.30-0.46 kWh/m3, as well as tariff differences at certain hours (Peak Load Time). From the simulation results and analysis of existing conditions in the junok pump distribution area, full pump optimization is needed to increase pump efficiency, improve the distribution network to meet design criteria by reducing headloss and adding pressure using booster pumps, and setting VSD patterns. So that there is a savings of Rp. 4,258,740 per month. Judging from the investment criteria, the recommendations given can be said to be feasible assessed by the BCR, PP, NPV, and IRR methods. In the implementation of energy efficiency improvement, it is necessary to strategically strengthen the institutional aspects by creating strategies that minimize weaknesses to take advantage of opportunities.
