Abstract

This study aims to evaluate the extent to which the Community Development and Empowerment Program (PPM) implemented by PT. Golden Great Borneo (GGB) in 2024 aligns with the actual needs of communities in the Ring 1 area, specifically Prabumenang and Banjarsari Villages, East Merapi District, Lahat Regency. Using a qualitative descriptive approach, the research combines analysis of official program documents and field observations with a structured Likert-scale survey involving 40 purposively selected beneficiaries. The study assesses eight core domains mandated in PPM guidelines: education, health, real income, economic independence, socio-religious-cultural aspects, environment, community institutions, and infrastructure. Findings show that the program received moderate appreciation from the community, with average perception scores ranging from 3.5 to 3.7. While education, health, and infrastructure were positively valued, key issues remain in benefit equity, long-term sustainability, and participatory implementation. The study contributes a novel, integrative assessment model combining community perception data with program alignment analysis. It concludes that future PPM efforts should adopt a more impact-oriented, community-driven approach, particularly by strengthening environmental programs, preventive health initiatives, post-training support, and local institutional capacity to ensure sustainable development in mining-affected regions.

Abstract

PT Dizamatra Powerindo merupakan perusahaan independen di bidang pertambangan batubara dengan target produksi 378.000 ton dan target pengupasan overburden sebesar 2.872.800 BCM pada tahun 2025. Penelitian ini bertujuan untuk mengevaluasi produktivitas alat gali muat excavator Komatsu PC 1250 dan alat angkut OHT Komatsu 785 dalam kegiatan pengupasan overburden di Pit Tengah. Metode penelitian menggunakan pengambilan data cycle time sebanyak 30 data pada bulan Februari 2025 dengan pendekatan observasi langsung dan pengolahan data statistik. Hasil penelitian menunjukkan produktivitas alat gali muat sebesar 542,029 BCM/jam dengan cycle time rata-rata 22,29 detik, sedangkan produktivitas alat angkut mencapai 103,617 BCM/jam dengan cycle time rata-rata 17,49 menit. Efisiensi kerja mencapai 83% dengan match factor 0,76, yang menunjukkan adanya waktu tunggu bagi alat gali muat menunggu alat angkut. Untuk mengoptimalkan kinerja unit dan mencapai match factor 0,95, disarankan pengurangan jumlah unit alat angkut menjadi 5 unit untuk mengurangi waktu tunggu alat gali muat. Faktor-faktor yang mempengaruhi produktivitas meliputi kondisi jalan angkut, cuaca, bucket fill factor (0,71), dan swell factor (0,85). Penelitian ini memberikan kontribusi dalam optimasi operasional penambangan batubara khususnya dalam pengupasan overburden menggunakan alat berat.

Abstract

This study discusses the control of acid mine drainage (AMD) using quicklime (CaO) in the AL-14 (Taman) Sludge Settling Pond (KPL) at the Air Laya Mine site of PT Bukit Asam Tbk, Tanjung Enim, South Sumatra. Acid mine drainage is waste formed due to the oxidation of sulfide minerals, which can degrade water quality and damage the environment. This study aims to analyze the AMD control system, determine the ideal dosage of quicklime, calculate liming costs, and identify factors that influence daily lime requirements. The research method used is an experimental and observational approach, including laboratory tests using the jar test method and direct observations in the field during the period of April 28 to June 30, 2025. Tests were conducted on acid mine drainage samples with varying doses of quicklime (0–0.5 gr/L) to determine the optimum dose for increasing pH and reducing TSS. The test results showed that the ideal dose of quicklime to increase pH from 5.20 to the standard range (6–9) is between 0.1121–0.2812 gr/L, with an actual requirement of approximately 5 sacks/day. However, field usage reached an average of 10 sacks/day, causing cost overruns of up to Rp 381,600,000/month. The main factors influencing lime requirements are rainfall and runoff flow. This study provides recommendations for the implementation of an automatic monitoring system and blending system to improve the efficiency of AAT processing and reduce chemical waste.
