Abstract

Mita Mulia Hotel is located within the largest university in Aceh Province, Indonesia. The number of rooms occupied increases when events such as graduation ceremonies occur, resulting in a higher volume of wastewater generation. Mita Mulia Hotel produces approximately 30,000 liters of wastewater from the cafe, kitchen, laundry, bathrooms, and washbasins daily. Preliminary water quality tests for Mita Mulia Hotel's wastewater, including COD, BOD, TSS, Oil and Grease, and Ammonia parameters, have been shown to exceed the standards set by the Minister of Environment and Forestry Regulation Number 68 Year 2016 regulate Domestic Wastewater Quality Standards. Mita Mulia Hotel uses the Anaerobic-Aerobic Biofilter method to treat their wastewater, equipped with Grease Trap Tank, Initial Sedimentation Tank, Anaerobic Biofilter Tank, Aerobic Biofilter Tank, and Final Sedimentation Tank. The total planned land area required is 18.75 square meters, with the Bill of Quantities (BoQ) encompassing activities ranging from standard soil excavation for construction to reinforcement works with plain concrete steel (rebar). These include formwork for floors, walls, and roofs.

Abstract

This research aims to prepare natural coagulants from Angsana leaves (Pterocarpus indicus willd) for Palm Oil Mill Effluent (POME) treatment, especially reducing main variables such as TSS, COD, and pH. The amounts of 100 mesh Angsana powder (5, 10, 15, and 20 grams) were extracted using NaCl solvent with concentrations of 0.25 M and 0.5 M, respectively. The extract (200 mL) were added to 500 mL of POME and stirred (180 rpm) for 30 minutes. The concentrations of TSS, COD, and pH in POME were analyzed. Results showed that the coagulation-flocculation process using Angsana leaves powder was able to reduce COD by 55.79% at a coagulant dose of 5 g/L with 0.25 M NaCl solvent and TSS by 99.75% at a dose of 20 g/L with 0.25 M NaCl solvent. However, treatment using Angsana leaves extract was not able to reduce COD to the predetermined quality standard limits while the TSS value met the quality standard. Therefore, POME treatment still requires further processing.
