Abstract

Peran PDAM Unit Guosari Kabupaten saat ini sangat menunjang sekali dalam penyediaan air di Desa Guwosari, Pendowoharjo, Sewon, dan Bantul. Namun dalam pelaksanaannya PDAM Unit Guosari seringkali mengalami berbagai kendala, sehingga diperlukan evaluasi karena tingkat pelayanan yang rendah 13,06%, tingkat kehilangan air yang tinggi 44,54%, tekanan air yang rendah, kontinuitas, kualitas, dan kuantitas yang tidak sesuai yang diharapkan oleh masyarakat.

Tujuan dalam penelitian ini adalah mengevaluasi distribusi pelayanan air bersih dan merencanakan pengembangan pelayanan PDAM Tirta Dharma sepuluh tahun mendatang, dengan ruang lingkup meliputi aspek teknik, aspek sosial, aspek kelembagaan, dan aspek keuangan. Pembahasan dilakukan dengan menggunakan metode deskriptif berdasarkan kondisi sistem penyediaan air bersih PDAM Unit Guosari, kemudian dilakukan kajian aspek teknis, aspek kelembagaan, aspek sosial, dan kelayakan proyek.

Hasil evaluasi menunjukkan bahwa tingkat pelayanan yang rendah, tingkat kehilangan air yang tinggi, tekanan air yang rendah, kontinuitas, kualitas, dan kuantitas yang tidak sesuai dengan yang diharapkan disebabkan oleh jumlah pelanggan yang tidak merata, waktu operasi pengaliran yang kurang, karakteristik pompa yang tidak sesuai, tingkat kebocoran air yang tinggi, dan debit air yang dikonsumsi oleh masyarakat lebih rendah daripada hasil Real Demad Survey. Pengembangan PDAM Unit Guosari pada Tahun 2015, diperlukan kegiatan penambahan dua buah sumur, penambahan dua unit reservoir, peningkatan pengolahan dan produksi, penambahan dan penggantian pipa, dan pengurangan kebocoran air. Total biaya yang dibutuhkan adalah Rp. 8.026.219.000,00 dengan hasil penilaian kelayakan investasi menunjukkan IRR = 11,55% (>10%), NPV = Rp. 241.305.223,49 (NPV +) dan PI = 1,03 (>1) menunjukkan bahwa investasi ini layak dan diperkirakan menguntungkan PDAM maupun pemerintah daerah untuk dilaksanakan.

Guosari PDAM Unit at the present has given much help in providing fresh-water for the people of Guwosari, Pendowoharjo, Sewon, Bantul village. This unit, however, has frequently encountered various obstacles in performing its function. It is service quality is low, that is 13,06%, the leaking water level is 44,54%, the water pressure is low. The continuity, quality, and quantity are out of the customers' expectation. For that reason, evaluation is necessary.

The purposes of this study are to evaluate the fresh water distribution service and to make ten years development planning for PDAM Tirta Dharma. The scope includes aspects of techniques, institution, society, and financial feasibility. To begin with, discussion is conducted by means of descriptive method illustrating the factual condition of fresh water supplying system performed by Guosari PDAM Unit. Next, necessary study is conducted in relation to the aspects of techniques, institution, society, and financial feasibility.

The result of the evaluation shows that the persisting problems are due to unevenness of customer distribution, insufficient flow operational time, unsuitable pump characteristics, high level of leaks, and consumed water amount that is lower than the Real Demad Survey result. In 2015, Guosari PDAM Unit should have added two units of well and two units of reservoir. By that time, this unit should also have improved the quality of processing and the quantity of production. In addition, this unit should also have added new pipes or replaced the old ones to decrease the leak level. The total cost required for this project is Rp. 8.026.219.000,00. Investment feasibility judgment shows IRR = 11,55% (>10%), NPV = Rp. 241.305.223,49 (NPV+) and PI = 1,03 (>1). It means that the investment will be feasible and profitable for both PDAM and the local government.
