Abstract

The availability of clean water is a vital requirement in supporting mining operations, especially for bathing, washing, and toilet (MCK) purposes at Mess Rayeuk. To date, clean water supply is still entirely dependent on drilled wells, which causes problems such as high operational costs, dependence on groundwater, and environmental risks. This study aims to optimize the use of alternative water sources from Void Pit A through the implementation of a Water Treatment Plant (WTP) as an effort to reduce dependence on drilled wells. The research method uses the Quality Control Circle (QCC) approach with the PDCA (Plan–Do–Check–Action) model. Primary data were obtained from daily water usage records, flow meter monitoring results, and water quality tests in the laboratory, while secondary data came from operational cost reports and groundwater extraction permit documents. The results showed that after the WTP was operational, the use of drilled well water decreased by 57.12%, with the total clean water supply from the WTP reaching 1,089,000 liters in 15 days. In terms of costs, WTP is more efficient with savings of 22.9% compared to the use of drilled wells, and laboratory test results also ensure that the water processed by WTP meets all quality standard parameters according to Minister of Health Regulation No. 32 of 2017. In conclusion, the implementation of WTP has succeeded in increasing the availability of clean water, reducing operational costs, and reducing groundwater exploitation so that it not only provides economic and operational benefits, but also strengthens the company's commitment to supporting environmental sustainability.

Abstract

This improvement aims to evaluate the effectiveness of the use of solar cell systems in improving energy efficiency and WiFi network productivity in coal mining environments. The research method involves the installation of solar cell systems and the measurement of energy performance and productivity before and after implementation. The implementation of solar cell systems on WiFi networks in mining environments can improve energy efficiency and productivity. This study aims to analyze the influence of the implementation of solar cell systems on fossil energy use and environmental impact. The results show that the implementation of the solar cell system can reduce the use of fossil energy by 75% and reduce greenhouse gas emissions by 60%. The implementation of the solar cell system can also increase productivity by 25%. Therefore, the implementation of a solar cell system on a WiFi network in a mining operational environment is highly recommended. The results showed a significant improvement in the energy efficiency and stability of the WiFi network, which had a positive impact on operational productivity. The results of the study show that the use of solar cells can significantly reduce the consumption of electricity/fossil energy, as well as increase the availability of WiFi networks to support PT AMM's operational support activities. The implication of this study is the great potential of the use of solar energy to improve operational efficiency and reduce environmental impact.
