Abstract

Waste reduction efforts need to be made to reduce the burden of landfill in processing waste. The absence of a study on the potential for reducing domestic waste at PT X is an obstacle for the company to determine the right waste management scenario. PT X's waste management still adheres to the collection, transportation, and disposal system.  The test of this study is to analyze the potential waste reduction that can be done by PT X. This study was carried out by collecting waste transportation data and waste composition data obtained through the SNI 19-3964-1995 method. Waste transportation data will be reduced by waste composition data that has the potential to be used for kembai. The average waste transported to landfill is 6480 kg / month with the composition of waste dominated by 26.09% of food waste and plastic waste. Total waste that can be reduced by 52.07% by managing organic waste into compost and collecting and selling waste that still has a selling value. By carrying out this management, the average waste disposal of PT X can be reduced to 3374 kg / month.

Abstract

Domestic wastewater can be sourced from industrial activities, one of which is the Feedmill Industry. The Surabaya Feedmill Industry has been treating domestic wastewater using a WWTP. The management of domestic wastewater is based on the Technical Approval (PERTEK) of Wastewater Utilization for Application to Land. Based on the results, there are parameters that do not fulfill the quality standards. The parameter is Biological Oxygen Demand (BOD), an evaluation is needed to enhanced WWTP performance. The purpose of this research is calculating the percent removal of BOD, COD and TSS parameters in the biological treatment unit and identifying factors that can affect the removal of BOD parameters in the existing conditions of the biological treatment unit in the Surabaya Feedmill Industry. The method used is a literature study using the Ludwig Sasse equation. In the calculation of the average water discharge of 5.93 m³/day, only 29.6% of the planned discharge. The results of the calculation of HRT in biological unit processing have not met the design criteria, except for the aerobic biofilter. The BOD/COD ratio is 0.33. According to the existing calculation, the final result for the BOD parameter is 5.11 mg/L, COD is 24.38 mg/L and TSS is 37.33 mg/L. The design air requirement is 27.64 m³/day. Other factors that affect BOD removal are Dissolved Oxygen (DO) levels in the Aerobic Biofilter, nutrient requirements, and Food to Microorganism (F/M).
