Abstract

The Jagir River in Surabaya City faces critical ecological pressure due to the accumulation of urban wastewater along a 10 km segment from Wonokromo to Wonorejo. This study evaluated the River Water Pollution Load Capacity (RWPLC) and its natural self-purification capacity using the static mass balance method and Streeter-Phelps deterministic modeling. The baseline analysis revealed a total capacity deficit for Total Phosphorus (peaking at -628.99 kg/day in the middle segment) and a COD deficit of -4,354.56 kg/day in the downstream. Conversely, BOD, TSS, and the DO Sag Curve profile remained safe, with a minimum critical Dissolved Oxygen (DO) of 5.557 mg/L downstream (Mangrove Area) driven by high natural reaeration and rapid stream velocity (u = 4.51 m/s). Simulations proved that the 50% BOD Load Reduction Scenario is the most effective intervention to permanently eliminate oxygen deficits. Governance policies are recommended to focus on preventive strategies through strict industrial effluent regulation.

Abstract

Industri kelapa sawit menghasilkan limbah cair (Palm Oil Mill Effluent / POME) dengan beban organik tinggi, di mana Biochemical Oxygen Demand (BOD) dapat mencapai 25.000 mg/L sehingga memerlukan pengolahan ketat agar tidak mencemari lingkungan. Penelitian ini bertujuan mengevaluasi efisiensi penyisihan BOD pada Kolam Anaerobik dan Kolam Fakultatif untuk pemenuhan baku mutu Land Application. Metode yang digunakan ialah pendekatan kuantitatif deskriptif melalui evaluasi teknis operasional sistem kolam stabilisasi di IPAL PT. X. Data diperoleh melalui grab sampling pada inlet dan outlet setiap kolam, kemudian dianalisis menggunakan efisiensi penyisihan dan Hydraulic Retention Time (HRT). Hasil menunjukkan Kolam Fakultatif menyisihkan BOD sebesar 50%, sedangkan Kolam Anaerobik 1 mencapai efisiensi tertinggi sebesar 81%. Kondisi HRT yang memadai, yaitu 19,42 hari dan 20,6 hari, mendukung tingginya efisiensi sehingga konsentrasi akhir BOD turun menjadi 125,0 mg/L dan memenuhi baku mutu lingkungan.
