Abstract

Sistem penyediaan air bersih menjadi perhatian khusus setiap daerah perkotaan di Indonesia tidak terkecuali di Kecamatan Tanjung dan Murung Pudak sebagai ibukota Kabupaten Tabalong Provinsi Kalimantan Selatan. Geliat industri di kabupaten ini, terutama tambang batubara, minyak bumi, serta perkebunan sawit dan karet memicu terjadinya pertumbuhan pelanggan PDAM seiring dengan pertumbuhan penduduk yang cukup tinggi. Penambahan pelanggan tanpa disertai analisis yang baik mengakibatkan terjadinya peningkatan beban pelayanan PDAM, sehingga sistem distribusi air tidak lagi mampu memenuhi kebutuhan air pelanggan terutama pada saat jam puncak pemakaian. Saat ini, tingkat pelayanan PDAM Kabupaten Tabalong pada akhir tahun 2016 mencapai 67,78% dari jumlah penduduk sebanyak 82.153 jiwa dengan prosentase kehilangan air sebesar 28,24%. Tujuan dari penelitian ini adalah menyusun dan menetapkan upaya untuk mengoptimalkan sistem distribusi air minum eksisting dengan melakukan analisis pada aspek teknis, aspek finansial, dan aspek kelembagaan. Analisis aspek teknis meliputi perhitungan kehilangan air menggunakan neraca air, potensi sifat korosif pada air yang didistribusikan serta analisis jaringan distribusi menggunakan EPANET 2.0. Aspek finansial dan kelembagaan meliputi penilaian kinerja perusahaan dengan mengacu pada Keputusan Menteri Dalam Negeri Nomor 47 tahun 1999 tentang pedoman penilaian kinerja PDAM serta Badan Pendukung Pengembangan Sistem Penyediaan Air Minum (BPPSPAM) tentang petunjuk teknis penilaian kinerja PDAM. Hasil analisis menunjukkan bahwa kehilangan air yang terjadi sebesar 28,24% dengan komposisi kehilangan air fisik sebesar 23,86% dan kehilangan air non fisik sebesar 4,38%. Diperlukan penyesuaian nilai pH air dalam sistem distribusi sesuai index Langelier sebesar 7,98 untuk reservoir Agung dan 7,93 untuk reservoir Belimbing agar air tidak bersifat korosif maupun kerak. Analisis Epanet 2.0 menunjukkan bahwa pada saat jam puncak terdapat titik-titik pelayanan yang kekurangan tekanan dan headloss yang tinggi, sehingga diperlukan penambahan, penggantian pipa serta penambahan booster agar sistem jaringan distribusi mampu memenuhi kebutuhan pada saat jam puncak. Hasil penilaian kinerja PDAM dari Kepmendagri Nomor 47 Tahun 1999 mendapat nilai 53,11 dengan kategori cukup dan Petunjuk Teknis BPPSPAM mendapat nilai 2,87 dengan kategori sehat. ============================================================ Water supply system becomes particular concern to every urban area in Indonesia including Tanjung and Murung Pudak Subdistrict as the Capital Regency of Tabalong, South Kalimantan Province. Industrial growth in this district, especially coal mines, petroleum and plantations making customer growth water supply company of Tabalong Regency along with a fairly high population growth. The addition of customers without good analysis leads to an increase in service burden, so that the water distribution system is no longer able to meet the water needs of customers especially during peak hours of use. Currently, level of service water supply company of Tabalong Regency at the end of 2016 reached 67,78% of the total population of 82.153 inhabitants with a water loss percentage of 28.24%. The purpose of this research is to compile and define the effort to optimize the existing drinking water distribution system by analyzing the technical aspects, financial aspects, and institutional aspects. Technical aspect analysis includes calculation of water loss using water balance, potential corrosive in distributed water as well as distribution network analysis using EPANET 2.0. Financial and institutional aspects including the assessment of company performance refers to Keputusan Menteri Dalam Negeri Nomor 47 tahun 1999 about performance appraisal guidelines water supply company and Badan Pendukung Pengembangan Sistem Penyediaan Air Minum (BPPSPAM) about technical guidance on performance appraisal water supply company.The result of the analysis shows that the water loss is as big as 28,24% with the composition of physical water loss of 23.86% and non-physical water loss of 4.38%. Adjustment of water pH values in the distribution system is required corresponding index Langelier in 7,98 for the Agung reservoir and 7,93 for the Belimbing reservoir so that water is not corrosive or crust. Epanet 2.0 Analysis shows that during peak hours there are service points that lack pressure and high headloss, so it needs addition, replacement of pipes and addition of booster so that the distribution network system is able to meet the needs during peak hours. water supply company performance appraisal results from Kepmendagri Nomor 47 Tahun 1999 got the score 53,11 with “enough” category and Technical Instructions BPPSPAM got the score 2,87 with healthy category.
