Abstract

Based on the calculation of Non-Revenue Water/Un-billed Water (NRW/ATR), it is known that the value of NRW (Non-Revenue Water/Unbilled Water) in the Meter Area (DMA) District of Perum Bumi Kepongpongan Indah, Cirebon Regency with 204 SR subscribers, in February 2020 was relatively high, at 50.92%. The purpose of this study was to determine the level of water loss by looking for causes arising from water leaks, knowing the location of water loss both physically and non-physically, and knowing how to control Non-Revenue Water (NRW) water loss. The methodology used is to collect secondary data and primary data. Secondary data were obtained from the Cirebon City Water Supply Corporation, including images of the DMA distribution network and monthly customer water usage data taken from February to April 2020. Primary data was obtained by means of surveys and direct field observations by testing the steptest in one test. DMA. The result of controlling and decreasing NRW/ATR is that it can reduce the value of NRW/ATR from 50.92% in June 2020 down to 46% based on (WB 0) and in August 2020 down to 25% based on the results of simultaneous readings (WB 1). Pressure also needs to be considered, because pressure that is too high can also increase water loss. So that the Pressure Reducing Valve (PRV) is installed which can reduce excess pressure, from the PRV installation reducing the water loss rate from 25% in August 2020 to 20% in February 2021.

Abstract

Pemasangan pipa distribusi HDPE Ø 300 mm crossing rel kereta api di Jl. RA Kartini Kota Cirebon dilakukan sebagai upaya untuk meningkatkan kapasitas dan menjaga kontinuitas pelayanan air bersih, menertibkan jaringan perpipaan, serta meningkatkan tekanan dan supply air ke wilayah Pesisir dan sekitarnya. Penelitian ini bertujuan untuk mengetahui aspek keamanan konstruksi pemasangan pipa distribusi HDPE Ø 300 mm dengan metode Jacking System serta mengetahui efektifitas dari perencanaan pemasangan pipa distribusi tersebut dengan melakukan analisis hidrolis. Metode pelaksanaan pemasangan pipa yang digunakan oleh Perumda Air Minum Tirta Giri Nata Kota Cirebon adalah metode jacking system untuk pipa sepanjang 48,70 m sesuai dengan hasil kajian optimalisasi jaringan distribusi Kota Cirebon tahun 2019 menggunakan program aplikasi EPANET. Hasil analisis distribusi beban di atas rel kereta api yang akan bekerja pada pipa beton yaitu beban merata pada lapisan tanah asal σ2 = 9,61 N/cm2 = 0,98 Kg/cm2 dan beton K-500 memiliki kekuatan tekan beton sebesar 500 kg/cm2 atau fc 41,50 mpa atau 4.900 N/cm2 sehingga pipa beton K-500 Ø 450 mm crossing rel kereta api Jl. Kartini Kota Cirebon dapat menahan pembebanan yang bekerja pada pipa beton tersebut berupa beban mati/statis dan beban hidup/dinamis (beban vertikal) dan beban horizontal. Hasil analisis hidrolis pada jam puncak menunjukkan bahwa pemasangan pipa baru HDPE dengan ukuran Ø 300 mm di Jalan Kartini dari Crossing Rel Kereta Api Sampai Dengan Jl. Veteran Sisingamangaraja Sepanjang 873 Meter meningkatkan sisa tekan di kawasan Wilayah Pusat Pelelangan Ikan Pesisir. Dari hasil penelitian ini maka dapat disimpulkan bahwa metode Jacking System untuk pemasangan pipa distribusi HDPE Ø 300 mm crossing rel kereta api di Jl. RA Kartini Kota Cirebon memenuhi aspek keamanan konstruksi serta dapat meningkatkan pelayanan berdasarkan analisis hidrolis yang dilakukan.
