Abstract

Organic waste from household activities and traditional markets causes large volumes of waste to be generated every day at the Mamuju landfill. To reduce the volume of organic waste, efforts need to be made to minimize generation through innovation. This research aims to determine the effectiveness of differences between variations of gray water mud and cow dung on physical quality of compost (pH, temperature, humidity), macro elements (Nitrogen, Carbon, Phosphorus, C/N ratio , Kalium) in the decomposition of organic waste. This research involves conducting quasi experimental research on organic waste using bioactivators made from gray water sewer mud and cow dung. This research consisted of 6 (six) treatments and 1 control, so 7 (seven) composters were made. The final result of composting after analyzed for N content after 28 days are K (0,54), GW100(0,6), GW200(0,53), GW300(0,62), KS100(0,61), KS200(0,59), KS300(0,58). For P content are K(0,14), GW100(0,15), GW200(0,2), GW300(0,18), KS100(0,18), KS200(0,20), KS300(0,23). For K content are K(0,36), GW100(0,26), GW200(0,47), GW300(0,4). KS100(0,44), KS200(0,42), KS300(0,51). C/N ratio are K(70,7), GW100(58,06), GW200(87,1). GW300(56,54), KS100(60,85), KS200(58,87), KS300(60,08). And for C Organic content are K(38), GW100(35), GW200(46), GW300(35), KS100(37), KS200(35), KS300(35). The final results of composting showed that the quality of the compost with the addition bio activator of gray water mud and cow dung for 28 days is not eligible of SNI 19-7030-2004. This is due to husks have a fairly high carbon value, so 28 days is not enough to decompose into good quality compost.

Abstract

Wastewater contains a variety of heavy metals, one of which is cadmium (Cd) which causes adverse effects on both the environment and health. Coffee grounds can be used to reduce Cd in wastewater so this study aims to determine the reduction of Cd levels using coffee grounds. The type of research used is an experiment to see the decrease in Cd levels using carbonized and non-carbonized coffee grounds. The samples used were taken from the leachate water source at one of the landfills in Makassar City. Sampling was done using the grab sampling technique. The results showed that the use of uncarbonized and carbonized coffee grounds was effective in reducing Cd levels in Makassar City Tamangapa Landfill leachate water with an average decrease of 0.048 and 0.023 µg/L. Uncarbonized coffee grounds have a higher ability to reduce Cd in leachate so that it can be used as an alternative in the wastewater treatment process.
