Kajian Kebutuhan Air Bersih dengan Cara Optimalisasi Air di Waduk Manggar Balikpapan

Study of Clean Water Needs with Water Optimization in Manggar Balikpapan Reservoir

Abstract

Penelitian ini melakukan penelitian pada air waduk Manggar di Kota Balikpapan. Penelitian dilakukan dengan metode kuantitatif. Data primer yang digunakan hasil dari kunjungan langsung ke lokasi penelitian dengan melakukan observasi dan wawancara kepada PDAM Kota Balikpapan. Data sekunder merupakan data yang diperoleh dari PDAM Balikpapan, dan dari berbagai sumber buku. Metode pengoptimalisasian air waduk Manggar menggunakan perhitungan output air yang terjadi. Metode ini untuk mengetahui berapa lama waduk Manggar dapat bertahan tanpa hujan. Dilakukan perhitungan kebutuhan air baku PDAM, pengukuran curah hujan, penguapan air, dan kapasitas waduk Manggar. Perhitungan kapasitas waduk menggunakan simulasi debit waduk Manggar saat Instalasi Pengolahan Air Kilometer 12 dimaksimalkan dan jika air waduk manggar diambil lagi dengan debit 300, 500, dan 600 liter/detik. Berdasarkan hasil analisis yang telah dilakukan, dapat disimpulkan bahwa kapasitas 300 liter/detik dapat bertahan 110 hari, dengan kapasitas 500 liter/detik dapat bertahan 97 hari, dan dengan kapasitas 600 liter/detik dapat bertahan 91 hari dengan asumsi tanpa terjadi hujan paling lama 90 hari.

 

This study was conducted on Manggar reservoir in Balikpapan city. The study used by quantitative method. The primary data of this study was obtained from visited Manggar reservoir by conducting observations and interviews with employees of PDAM Balikpapan. The secondary data was taken from PDAM Balikpapan’s data, and from various book sources. The method of optimizing the Manggar reservoir by calculated the output of the water that occurs. This method was used to find out how long the Manggar reservoir can last without rain. The needs of PDAM’s water has been calculated, measurements of rainfall, evaporation of water, and the capacity of the Manggar reservoir. Calculation of reservoir capacity used Manggar reservoir discharge simulation at Kilometer 12 Water Treatment plant is maximized and if water from the Manggar reservoir is taken again with 300, 500, and 600 liter / second. Based on the results of the analysis that has been carried out using the reservoir water optimization method, it can be concluded that with a capacity of 300 liters / sec can last 110 days, with a capacity of 500 liters / sec can last 97 days, and with a capacity of 600 liters / second can last 91 days.
