Abstract

Peningkatan kebutuhan air yang semakin pesat mendorong peningkatan efisiensi jaringan distribusi air yang semakin tinggi pula baik dalam segi pemenuhan kebutuhan air maupun dari segi biaya yang dibutuhkan. Beberapa kasus kurangnya pemenuhan kebutuhan air sering ditemukan pada daerah Surabaya Barat. Grand Pakuwon Township merupakan sebuah proyek pembangunan yang dicanakan untuk menjadi Superblok di Surabaya Barat, tentu kebutuhan air akan menjadi sangat tinggi di daerah tersebut. Oleh karena itu, penulis mengangkat topik analisis jaringan distribusi air di Grand Pakuwon Township untuk melihat apakah jaringan distibusi tersebut telah memenuhi standard tekanan minimum yang telah ditetap atau tidak dan apakah masih terdapat ruang untuk optimisasi jaringan distibusi tersebut dalam hal biaya dengan diameter sebagai decision variable. Dalam penelitian ini, penulis menggunakan metode Generalized Reduced Gradienti (GRG) berbasis head loss dimana metode ini cukup efektif dalam menyelesaikan permasalahan optimisasi nonlinear seperti jaringan distribusi air. Adapun Hasil yang didapatkan dengan menggunakan metode ini adalah penghematan sebesar 22.95% dari total biaya investasi awal dan error head loss antara simulasi menggunakan EPANET 2.2 dan perhitungan dengan menggunakan Root Mean Squared Error (RMSE) adalah 0.21025.

The rapid increase in water demand has led to an increase in the efficiency of the water distribution network, which has also increased both in terms of meeting water needs and in terms of the required costs. Several cases of lack of fulfillment of water needs are often found in the West Surabaya area. Grand Pakuwon Township is a development project planned to become a Superblock in West Surabaya, of course the demand for water will be very high in that area. Therefore, the author raises the topic of analyzing the water distribution network in Grand Pakuwon Township to see whether the distribution network meets the predetermined minimum pressure standards or not and whether there is still room for optimizing the distribution network in terms of costs with diameter as the decision variable. In this study, the authors used the Generalized Reduced Gradient (GRG) method based on head loss where this method is quite effective in solving nonlinear optimization problems such as water distribution networks. The results obtained using this method are savings of 22.95% of the total initial investment cost and error head loss between simulations using EPANET 2.2 and calculations by using Root Mean Squared Error (RMSE) is 0.21025.
