Abstract

Background: Liquid waste that is not properly disposed of and managed can have a negative impact on the environment. The frequent negligence of employees in monitoring the full sediment pond causes the wastewater to flow to the ground surface area and can flow into the river. The existence of this Microcontroller Water level tool serves as a warning of overflow of liquid concrete batching plant waste.Objective: Find out the effect of using a water level microcontroller on warning the overflow of liquid concrete batching plant waste in the construction industry of Yogyakarta. Method: The type of research used in this study is a quasi-experiment with a Posttest Only Design or research design. The research was conducted in the industrial liquid concrete waste storage pond of Yogyakarta construction industri. Result : Mikrokontroller Water Level has a successful performance as a warning of overflow of liquid concrete batching plant waste with an average accuracy value of 100%. It can be stated that the water level microcontroller tool is effective as a warning notification of batching plant liquid waste overflow. The results show that there is an effect of using a microcontroller tool on warning the overflow of liquid concrete batching plant waste. Conslusion : Microkontroller water level device has successful performance as a warning of overflow of liquid concrete batching plant waste at Yogyakarta construction industri.

Abstract

Screen printing liquid waste contains heavy metals, high organic matter, and various pollutants such as ammonia and color that can endanger environmental stability if not managed properly. The results of the examination of the quality of Harno Screen Printing liquid waste in Moyudan obtained a Chemical Oxygen Demand (COD) level exceeding the quality standard of 1,069 mg/L. This study aims to determine the effectiveness of various thicknesses of rice husk and coconut shell activated charcoal media in reducing COD levels of Harno Screen Printing Industry liquid waste in Moyudan. The research method is Pre test - Post test with Control Group Design with pre-treatment (coagulation and sedimentation) followed by filtration and adsorption using variations in the thickness of rice husk and coconut shell activated charcoal media of 25 cm: 75 cm, 50 cm: 50 cm, and 75 cm: 25 cm. The reduction in COD after pre-treatment was 96.7%. The average COD reduction after filtration with a thickness of 25 cm: 75 cm was 40.45%, a thickness of 50 cm: 50 cm was 34.16%, a thickness of 75 cm: 25 cm was 71.4%, and a control of 6.93%. Conclusion, Activated charcoal filtration of rice husks and coconut shells 75 cm: 25 cm is the most effective thickness to reduce COD levels in Harno Screen Printing Industry liquid waste with a reduction of 71.4%.
