Abstract

The occurrence of mine acid water cannot be left unchecked because it has a negative impact on the surrounding community and the environment, both directly and indirectly. Therefore, the prevention and management of mine acid water is carried out by settling and neutralizing mine acid water using Lime and Chemical Cationic Coagulant. The purpose of this study is to find out the process of mining acid water management using the active method used at PT LCL. The result of this study is to determine the stages of mining acid water management starting from AAT pumping, chemical cationic coagulant, inlet channel pH measurement, inlet channel liming, checking the color and pH of outlet channel water if needed, as well as sedimentation, and then if the pH is in accordance with the environmental quality standards, mine acid water can be flowed to the receiving water body of the Penimir River. The dosage of lime and Chemical Cationic Coagulant used varies, according to the condition of the water in the KPL. If the pH of the water decreases, it will be sprinkled with lime, if the water is cloudy, chemical cationic coagulant will be sprinkled for precipitation. The pH of the water discharged into the river is already pH 6.

Abstract

Penelitian ini dilakukan untuk mengatasi dengan mengoptimalkan kinerja Belt Conveyor dan Bucket Wheel Stacker Reclaimer (BWSR) di PT. Anugerah Energi Pratama (AEP) yang disebabkan oleh berbagai kendala, seperti belt tergelincir, kerusakan bearing, dan pengaruh cuaca (hujan). Masalah tersebut berdampak pada menurunnya efektivitas distribusi batubara ke pembangkit. Tujuan dari penelitian ini adalah untuk mengoptimalkan kinerja belt conveyor dan BWSR dalam mendukung distribusi batubara di PT. AEP Kecamatan Rambang Niru. Permasalahan seperti belt tergelincir, kerusakan bearing, serta gangguan akibat hujan menyebabkan penurunan efektivitas sistem. Metode yang digunakan meliputi metode kuantitatif dengan pendekatan deskriptif analisis, mengetahui variabel yang mempengaruhi Mechanical Availability (MA), Physical Availability (PA), Use of Availability (UA), dan Effective Utilization (EUT). Hasil menunjukkan bahwa MA sebesar 94,07%, PA 94,67%, UA 89,44%, dan EUT 84,67%, yang menandakan sistem cukup andal namun masih dapat ditingkatkan. Faktor penghambat utama adalah kondisi cuaca dan kurangnya pemeliharaan rutin. Disarankan penerapan preventive maintenance, peningkatan inspeksi, serta pengendalian beban hopper untuk mengurangi downtime dan menjaga kontinuitas pasokan batubara.
