Abstract

The Operation of a Steam Power Plant (PLTU) can produce waste, one of which is liquid waste. Liquid waste will be processed at the Wastewater Treatment Plant (WWTP). The data in this study were collected through direct observation and interviews with the environmental department. This research was conducted at PT PLN (Persero) UPK Nagan Raya. The results showed that there were several sources of liquid waste, namely from boiler blowdown, water treatment plant (WTP), chemical cleaning, condenser cooling water, and fuel oil or lubricants. The resulting liquid waste discharge is 3,604 m3/day. At the PLTU PT PLN (Persero) UPK Nagan Raya there is a liquid waste treatment facility called the Wastewater Treatment Plant (WWTP). Chemical and physical processes occur in wastewater treatment at WWTP. There is no waste water quality that exceeds the quality standard limit. As long as the PLTU is still operating, it will produce liquid waste which will be processed at the WWTP.

Abstract

Industrial waste remains a problem in today's industrial era. The rapid development of industry has led to an increase in solid, liquid and gaseous wastes. Fly ash and bottom ash (FABA) are solid wastes from coal combustion. In this study, the authors wanted to know how to utilize fly ash and bottom ash solid waste in the manufacture of paving blocks in order to reduce non-B3 waste pollution by combining cement as the adhesive material. This research is descriptive with a qualitative approach, the data collection method is obtained through direct interviews with environmental operators who are responsible for the manufacture of paving blocks, and the data is taken from the PLTU Nagan Raya document. The results showed that the operational activities of PLTU Nagan Raya produce 60-70 tons of fly ash and 8-10 tons of bottom ash per day in the form of solid waste in one operating unit. Temporary Storage Area (TPS) Fly ash and bottom ash are coated with High-Density Polyethylene (HDPE), and Geonet. The results of the research suggest that the use of fly ash and bottom ash should not only be used in the manufacture of paving blocks and internal materials, but also in the manufacture of other external building materials, so as to reduce the amount of non-B3 waste at PLTU Nagan Raya.
