Abstract

Abstract: PT. X is a nut and bolt industry in Surabaya. PT. X treats their domestic wastewater in the Biofilter WWTP and uses it as water for sprinkling open spaces and green open spaces. This is interesting to learn because it can become material for study in domestic wastewater management systems in the industrial sector. The research method uses a qualitative data analysis approach with primary and secondary data sources. Data was collected through observation, interviews and documentation. The results obtained are the existing conditions of water management, starting from the use of clean water to produce waste water, processing, utilization, and efficiency of waste water utilization. The processing produces recycled water which meets quality standards, so that it can be used as watering open spaces and green open spaces. The efficiency of domestic wastewater utilization reaches 99%, with the benefits obtained, namely being able to reduce the cost of purchasing clean water for irrigation and reduce the volume and load of pollutants in water bodies.

Abstract

Abstract: PT. X is a company engaged in the field of Freezing Fish which in its production process produces B3 waste. The hazardous waste produced needs special management so that it does not pollute the environment. The purpose of this research is to determine the management of B3 waste technically based on the generation and type of B3 waste at PT. X. This research method uses primary data collection, secondary data and data analysis. PT. X has not been able to process B3 waste independently, so the manager cooperates with a third party to transport and process the resulting waste. The hazardous waste generated is Used Oil Filter (0.25 kg/month), Used Refrigerant (30 kg/month), Used lubricant packaging (0.25 kg/month), Used Oil (8.3 kg/month), Waste electronics (0.75 kg/month) as well as rags and B3 contaminated gloves (0.05 kg/month). PT. X requires TPS LB3 to store B3 waste before it is transported by a third party. The required dimensions of the TPS for hazardous waste are 4 m2
