Abstract

In 2023, the city of Bandung faced serious problems because the Sarimukti landfill caught fire and the city of Bandung experienced a "waste emergency". One of the programs launched is the construction of maggot houses in every sub-district in Bandung City with a target of processing 1 ton of organic waste/day. Mengger Sub-district is one of the sub-districts that received assistance to build maggot house. The land area of ​​the maggot house is 150 m2, managed by 4 officers. This study aims to identify various problems that must be resolved first so that the circular economy concept can be implemented at the Mengger Maggot House. The study was carried out by conducting observations, detailed surveys and in-depth interviews with various stakeholders in Mengger Sub-district. Observations were carried out to see the level of compliance of residents in sorting, a detailed survey was carried out on the waste collection and processing system at the maggot house, and in-depth interviews were conducted with assistants from Bandung City Environmental Service Office (DLH), maggot buyers, sub-district officials, maggot house officers, neighbourhood (RT) and hamlet (RW), and waste collector. Based on the results of observations, it was found that only some residents carry out sorting consistently, a collection system already exists in each RT/RW but they have not implemented a segregated waste collection system, and there is no system for transporting waste from the RW to the maggot house so that the amount of organic waste entering the maggot house is still low, no electricity and clean water, no choppers, leaks in the fly cage, and no diversification in maggot products. Through various socialization activities and Focus Group Discussions with all stakeholders, various agreements were obtained to resolve various problems at the Mengger Maggot House.

Abstract

Laundry wastewater is a source of environmental pollution that requires attention because it contains various compounds such as surfactants, suspended solids, and organic compounds that have the potential to damage the quality of groundwater and surface water. This study aims to optimize laundry wastewater treatment in a compact two-tube combination filter containing zeolite and activated carbon media. The filter treats artificial laundry wastewater made with three concentration variations. The variations tested were the flow rate and wastewater concentration. The results showed that the best removal efficiency occurred when the zeolite media was positioned in the inner tube with a downward flow direction, then flowed to the activated carbon media in the outer tube with a downward flow direction as well. The best removal efficiency was achieved at a medium flow rate (0.06 L/s and an initial concentration of COD of 143 mg/L, surfactant of 27.5 mg/L, and TSS of 117 mg/L) with a COD removal efficiency of 67%, surfactant of 64%, and TSS of 91%. Several parameters have met the quality standards stipulated in Yogyakarta Special Region Regulation No. 7 of 2016 concerning Wastewater Quality Standards. Therefore, a combination filter with two compact tubes using zeolite and activated carbon media could be a solution to improve environmental quality..
