Abstract

Evaluasi sistem distribusi air bersih bertujuan untuk mengetahui besar kebutuhan air, kondisi hidraulik, sisa klorin, dan kondisi hidran ideal di Zona Wendit. Perhitungan yang dilakukan yaitu proyeksi penduduk dengan metode aritmatik dan kebutuhan air berdasarkan Peraturan Menteri PU dan Peraturan Walikota Malang. Hasil perhitungan kebutuhan air kondisi eksisting yaitu 303,95 l/detik, kondisi pengembangan yaitu 704,81 l/detik dan kebutuhan dengan satu hidran yaitu 744,81 l/detik. Hasil tersebut tidak mencukupi karena ketersediaan air di Sumber Wendit II yaitu 370,16 l/detik. Oleh karena itu perlu menambahkan debit pada sumber. Selanjutnya melakukan simulasi dengan software WaterCAD V8i. Berdasarkan simulasi, didapatkan tekanan -1,29 – 10,56 atm, kecepatan 0 – 5,47 m/detik, headloss gradient 0 – 335,06 m/km pada kondisi eksisting dan tekanan 0,51 – 10 atm, kecepatan 0 – 3,79 m/detik, headloss gradient 0 – 15 m/km pada kondisi pengembangan. Hasil kecepatan tersebut belum memenuhi syarat, untuk itu perlu menambah katup penguras agar tidak tejadi sedimentasi. Hasil sisa klorin berdasarkan simulasi pada kondisi eksisting yaitu 0,503 – 0,797 mg/l dan kondisi pengembangan yaitu 0,312 – 0,398 mg/l. Hasil simulasi lainnya yaitu hidran dengan debit 40 l/detik didapatkan tekanan -35,45 – -34,22 atm. Hasil ini tidak memenuhi syarat pada SNI 03-1735-2000. Oleh karena itu perlu menambah jaringan baru untuk hidran agar tekanan dapat sesuai syarat.   Evaluation of fresh water distribution systems aims to determine the amount of water needed, hydraulic conditions, chlorine residual, and ideal hydrant conditions in the Wendit Zone. Calculations is done by the population projections with arithmetic methods and water demand based on the Regulation of Minister o Public Works and Regulation of Malang Mayor. The results of the calculation of the existing water condition requirements are 303.95 l/second, the development conditions are 704.81 l/second and the demand for a single hydrant is 744.81 l/second. These results were inadequate because of the availability of water at Sumber Wendit II was 370.16 l/second. Therefore it is necessary to add debit of water to the source. A simulation is done using WaterCAD V8i software, obtained a pressure of -1.29 – 10.56 atm, velocity 0 – 5.47 m/second, headloss gradient 0 – 335.06 m/km in the existing conditions and pressure 0.51 – 10 atm, velocity 0 – 3.79 m/second, headloss gradient 0 – 15 m/km under development conditions. The velocity results are not eligible, so it is necessary to add a drain valve to avoid sedimentation. The results of residual chlorine based on simulation in the existing conditions are 0.503 – 0.797 mg/l and the development conditions are 0.312 – 0.398 mg/l. Other simulation results are hydrants with a discharge of 40 l/second obtained pressure of -35,45 – -34,22 atm. These results do not meet the requirements of SNI 03-1735-2000. Therefore it is necessary to add a new network for hydrants so that the pressure can be in accordance with the requirements.

Abstract

The groundwater used for irrigation must have the quality according to its designation. The objective of this study was to assess the appropriateness of groundwater quality used as a source of irrigation water. This study was conducted on agricultural land in an area close to the coast and potentially intruded by sea water. The location of this study was groundwater irrigation land in the irrigation area of production wells SDTB 063, SDTB 064, and SDTB 342 located in Jenu District, Tuban Regency, East Java Province. Groundwater quality assessment was carried out using the IQWI model. Based on the IWQI value obtained, it can be shown that the groundwater quality from SDTB 064 and SDTB 342 production wells has low water usage restrictions, while the groundwater quality from SDJB 603 production well has moderate water usage restrictions. Groundwater quality with low water usage restrictions can be used as irrigation water on soils with moderate permeability with a recommendation to wash the salt. Groundwater quality with moderate water usage restrictions can be used as irrigation water on soils with moderate to high permeability with a recommendation to wash the salt. Farmers in the study area are recommended to be able to cultivate various alternative of high economic value crops that are suitable with the groundwater quality used as a source of irrigation water as stated in this study, while still making adjustments to agricultural land conditions and climatic conditions.
