Abstract

Kawasan industri Surabaya Industrial Estate Rungkut (SIER) saat ini melayani 12 tenant dengan konsumsi air bersih rata-rata 600 m³/hari, sementara kapasitas produksi unit Reverse Osmosis (RO) mencapai 1200 m³/hari. Seiring dengan target perusahaan dalam memperluas layanan, jumlah tenant diproyeksikan tumbuh menjadi 81 tenant dalam lima tahun ke depan, dengan konsumsi air meningkat menjadi 8.669.203 liter/hari atau setara 100,34 L/s. Penelitian ini bertujuan untuk menghitung kebutuhan air pada kondisi proyeksi, menganalisis kemampuan sistem distribusi eksisting, serta merancang ulang sistem perpippaan dan pompa yang sesuai. Pemodelan sistem dan validasi perhitungan menggunakan software Epanet 2.2. Hasil menunjukkan sistem eksisting dengan 1 pompa operasional dan 1 pompa standby tidak mampu memenuhi beban proyeksi, sehingga direkomendasikan untuk pergantian konfirgurasi pompa menjadi 4 pompa unit sentrifugal (kapasitas 36,1 L/s dan head 20 m per unit). Akan dilakukan juga pembesaran diameter pipa suction 4 inchi menjadi 14 inchi, serta beberapa jalur discharge menuju ke area terjauh menjadi 12 dan 14 inchi. Head effektif pompa hasil perhitungan analitis dengan nilai 27,68 m dan tervalidasi oleh simulasi Epanet mendapatkan nilai 27,43 m, dan menghasilkan error 0,9%. Diperhitungkan juga terkait dengan kebutuhan daya motor dan juga pompa untuk mengoptimalkan jaringan sistem proyeksi. Hasil penelitian ini diharapkan menjadi acuan teknis bagi PT SIER dalam perencanaan pengembangan sistem distribusi air bersih serta pertimbangan investasi dan pemeliharaan jangka panjang.

PT Surabaya Industrial Estate Rungkut (SIER) currently serves 12 tenants with an average clean water consumption of 600 m³/day, while its Reverse Osmosis (RO) production unit has a capacity of 1200 m³/day. In line with the company’s target to expand its service, the number of tenants is projected to grow to 81 tenants over the next five years, with water consumption increasing to 8.669.203 liters/day, equivalent to 100,34 L/s. This study aims to calculate water demand under projected conditions, analyze the capacity of the existing distribution system, and redesign an appropriate piping and pump system. System modeling and calculation validation were carried out using EPANET 2.2 software. The results show that the existing system, with 1 operating pump and 1 standby pump, is unable yo meet the projected load, so it is recommended to change the pump configuration to 3 centrifugal pump units (capacity of 36,1 L/s and head of 20 m per unit). The suction pipe diameter will also be enlarged from 4 inchies to 12 inches, along with several discharge lines toward the farthest areas being enlarged to 12 inchies. The effective pump head from analytical calculations is 28,27 m, and validated by EPANET simulation with a result of 28,08 m, yielding an error of 0,67%. The required motor and pump power were also calculated to optimize the projected network system. These findings are expected to serve as a technical reference for PT SIER in planning its clean water distribution system expansion and long-term investment and maintenance considerations.
