ABSTRAK

Kehilangan air dalam jaringan pipa distribusi air bersih merupakan salah satu masalah utama di PDAM. Penelitian ini membahas upaya teknis untuk mengoptimalkan sistem distribusi air minum dan menurunkan tingkat kebocoran teknis sehingga target pelayanan PDAM Menang Kota Mataram dapat tercapai. Data primer diperoleh dari real demand survey dari 166 responden baik pelanggan maupun non pelanggan PDAM.Serta site-visit dari lokasi reservoir dan kebocoran bersama tim dari PDAM Menang dan data sekunder diperoleh dari pihak-pihak terkait seperti kantor BPS Mataram serta Dinas PU Kota Mataram. Hasil analisa menunjukkan bahwa 476 pelanggan PDAM Menang menilai kualitas pelayanan tergolong baik 488 sedang dan 27 sangat baik. Pemakaian Air untuk Kota Mataram bulanJuni 2014 adalah sebanyak 913.0824 m3.Dengan tingkat kehilangan air yang dimiliki adalah sebesar 306. Hasil site visit menunjukkan kehilangan air disebabkan oleh perembesan karena sambungan pipa tidak sempurna 115 pipa rusak 92 pipa tertimbun 424 dan pipa mati 369. Untuk memudahkan pemantauan dan penanganan kebocoran 2 zona pelayanan harus dibentuk. Selain itu penanganan real losses dengan pendeteksian kebocoran pemeliharaan dan rehabilitasi dan peningkatan responsivitas dalam penanganan pipa bocor. Penanggulangan apparent losses juga diperlukan dengan menurunkan meter error human error computer error pencurian air dan penurunan tingkat kebocoran pada sistem distribusi.Dari analisa aspek pembiayaan diketahui diperlukan Rp. 7542034500 untuk mengeksekusi strategi-strategi pengurangan kebocoran pada sistem distribusi dimana 239 diperoleh dari biaya penyambungan baru dan retribusi bulanan serta 761 dari pemerintah. Analisa investasi menyebutkan Internal Rate of Return IRR sebesar 203 dan Benefit Cost RatioBCR 1 yang berarti proyek diatas masuk kategori layak. Selain itu metode Net Present alueNPV menunjukkan nilai positif yang berarti akan menguntungkan PDAM. Dalam aspek kelembagaan kinerja PDAM masih harus ditingkatkan lagi baik dalam bidang keuangan operasional maupun administrasi. Salah satu yang menjadi penyebab adalah kurangnya SDM. Maka untuk meningkatkan kinerja diperlukan peningkatan keahlian dan profesionalisme serta perekrutan SDM yang sesuai dengan keahliannya meningkatkan tingkat kebocoran baik teknis maupun non teknis serta pendataan kembali jaringan pipa PDAM Kota Mataram mengeksekusi program-program pengembanganpenyehatan PDAM meningkatkan pendanaan dari pusat maupun daerah serta menambah jumlah pelanggan dan meningkatkan cakupan pelayanan penduduk karena masih ada penduduk yang belum terlayani.


ABSTRACT

Water losses have been a major problem faced by district water companies in Indonesia. Thisstudy will elaborate on the technical efforts to optimize the clean water distribution system and reducing the leakage to fulfill the residents demand on district water company of Menang PDAM Menang city of Mataram. Primer data was gathered by real demand survey from 166 respondents and site visit to the detectable leakage location with team from PDAM Menang. While the secondary data was obtained from respectable party such as countyman office Mataram statistical bureau and the office of public service department of Mataram city. Analitical data has shown that 476 of PDAM Menang subscribers regard the service as good 488 medium and 27 as excellent. Total water usage for Mataram on June 2014 is 913.0824 m3with 306 losses. On the site visit it was found that water loss was caused by imperfection in pipe joint seam and weld 115 broken pipe 92 buried pipe under ground 424 and plugged off pipe 369. Is service zones were made up to make the monitoring and handly of water losses of the city of Mataram. It was in line with capacity to cater residents as per 2024 projection along with several technical and service assumptions. Other than that real losses must be handled by detection of losses maintenance and rehabilitation also reducing response time to fix any reported water leakage. Apparent losses are to be addressed by decreasing the water meter error human error computer error water thievery and reducing leakage in distribution system.From financial aspect analysis the calculated that Rp. 7542034500 investment is needed to execute the implementation of water loss reducing strategies whereby 239 will be taken from new and monthly subscription costwhile the other 761 from the government. Further calculation shown that Internal Rate of Return IRR value is 203 and Benefit Cost Ratio BCR 1 which means abovementioned project is feasible. Net Present Value NPV also shown positive value that renders the project to be profitable. On the institutional aspect lackness of personnel quality due to education insufficiency most of the employee are only high school graduates. In order to improve organiziational quality PDAM must create and make training programs to increase skills and professionalism a descent recruitment process must also be conducted to reduce technical and non- technical losses financial aid to conduct such program can be provided by central or provincial governement last but not leat is to increase the number of subscriber while at the same time increase service area
