DESAIN IPAL TERPADU DALAM MENDUKUNG IMPLEMENTASI SDGs PADA INSTITUSI PENDIDIKAN TINGGI

Abstract

Politeknik Negeri Lampung aims to establish a sustainable campus environment through the implementation of a safe and responsible laboratory wastewater management system. The Smart Food Technology Integrated Laboratory Building, which functions as the center of practical and research activities, generates wastewater from equipment washing, sample processing, and chemical usage. Laboratory wastewater quality analysis indicates that several parameters, including Lead (Pb), Iron (Fe), COD, BOD, and Total Coliform, exceed the limits stipulated in the Ministry of Environment Regulation No. 68/2016. With approximately 1,350 users, the estimated wastewater discharge reaches ±24.30 m³/day, necessitating an appropriate treatment system. This study designs a wastewater treatment plant (WWTP) employing an Anaerobic Filter (AF) as the core unit, complemented by heavy metal pretreatment, an aeration polishing unit, and disinfection. The piping system is designed to utilize gravity flow and is separated from stormwater drainage. The technical design is supported by a cost estimate totaling Rp 464,527,000.00, including 11% VAT. The proposed system is expected to enhance laboratory wastewater management, support the implementation of a Green Campus, and contribute to achieving SDG 6 on clean water and sanitation.
