Abstract

Indonesia is the 4th most populous country in the world. The main factors influencing the high rate of urban population growth are urbanization and migration. This condition causes an increase in the amount of waste generation, whether solid, liquid or gas waste. Therefore, efforts are needed to manage and process waste generation, one of which is composting. Composting is a form of reuse and recovery of resources from solid waste by decomposing organic matter with the help of organisms. One of the organisms that can be used as a waste decomposition agent is the Black Soldier Fly larvae. The composting process requires several requirements to produce good quality compost, namely the content of macro nutrients, namely N, P, K. This research was conducted on 3 February – 2 March 2022 at the Sahabat Alam Waste Bank (SAWB) Kp. Apar, South Pariaman, Pariaman City, West Sumatra. Sample testing was carried out at the Chemistry Laboratory of FMIPA UNP using the levels of Nitrogen (N) (Kjehdahl Method), Phosphorus (P) and Potassium (K) (X-Ray Fluorescence Method). The quality of N, P, K solid compost obtained from this study was nitrogen levels 6.09% (S.Week 1) and 9.324%, phosphorus levels 8.113% (S.Week 1) and 6.176% (S.Week 2), and 29.759% (S.Week 1) and 38.181% (S. .Week 2) for potassium levels.

Abstract

Padang City is a large city with an area of 694.96 km² and a population of 941,639 in 2018. The waste generated in 2018 amounted to 1,313,342.7 m³ (Padang City Environmental Agency, 2018). Landfills produce a type of liquid known as leachate. Leachate is a hazardous liquid generated from the decomposition of both organic and inorganic waste at the Final Disposal Site (TPA) of waste. This liquid contains high concentrations of organic, inorganic materials, and heavy metals that have the potential to contaminate groundwater, rivers, and surface water. This study aims to analyze the quality of leachate based on the Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD) parameters as the main indicators of organic pollution. Samples were taken from the outlet pond of the Air Dingin TPA in Padang City, then brought to and tested at the Andalas University Water Laboratory. The results showed a COD value of 450.4 mg/L and a BOD value of 250 mg/L. These values far exceed the quality standards established in the Minister of Environment Regulation No. 59 of 2016 concerning Wastewater Quality Standards. This study indicates that leachate requires further management before being released into the environment.
