Abstract

Overburden removal at Pit B did not meet the production targets for June and July 2025, which were set at 570,698.8 BCM and 400,986.56 BCM, respectively, while the actual production achieved was 507,071.66 BCM and 312,128.23 BCM. This study aims to determine the theoretical productivity of loading and hauling equipment and to identify the factors that hinder the achievement of production targets. The primary data used in this study include the cycle time of loading equipment, the cycle time of hauling equipment, bucket fill factor, and delay time. The secondary data required consist of swell factor, number of passes, bucket capacity, and available working time. The productivity of the loading equipment was 332.58 BCM/hour, while the hauling equipment achieved a productivity of 53.16 BCM/hour, with a match factor of 0.74. This indicates that the loading equipment experienced waiting time during loading operations due to the hauling equipment not operating optimally or at full capacity. The factors inhibiting the achievement of production targets include a narrow, waterlogged, and uneven working face; hard overburden material; a road grade of 16%, which exceeds the standard maximum of 12%; a curve road width of 15 m, which is less than the ideal minimum width of 19.95 m; undulating haul roads; narrow haul road width; and dusty road conditions.

Abstract

PT Astaka Dodol merencanakan penambangan kembali pada void Pit A1B Timur dan Barat di Site Macang Sakti, Sumatera Selatan, namun terkendala genangan air sehingga memerlukan perencanaan dalam proses pengeluaran air tersebut (mine dewatering). Penelitian ini termasuk dalam penelitian kuantitatif dengan tujuan melakukan analisis debit air masuk, mengevaluasi kinerja pompa yang ada, menentukan waktu pengurasan, serta merencanakan dimensi sump dan kolam pengendapan lumpur (KPL). Analisis hidrologi menggunakan distribusi Gumbel, metode Mononobe, dan metode Rasional, sedangkan evaluasi pemompaan menggunakan persamaan Bernoulli dan Darcy–Weisbach. Hasil penelitian menunjukkan total debit air masuk sebesar 3.405,73 m³/hari pada Pit A1B Timur (volume genangan 639.112,8 m³) dan 4.290,45 m³/hari pada Pit A1B Barat (volume genangan 831.552,90 m³). Untuk menguras genangan tersebut, direkomendasikan penggunaan kombinasi dua unit pompa: WP-05 (head 68 m, debit 290 m³/jam) dan WP-04 (head 83 m, debit 393 m³/jam) untuk Pit Timur dengan estimasi waktu pengurasan 63 hari, serta WP-05 (head 58 m, debit 330 m³/jam) dan WP-02 (head 64 m, debit 376 m³/jam) untuk Pit Barat dengan estimasi pengurasan 79 hari. Penambangan kuartal pertama didukung rancangan sump trapesium berkapasitas 18.771 m³ untuk menampung genangan air yang masuk. Total biaya pengurasan void berbasis konsumsi bahan bakar solar dan sewa pompa adalah 1.471.130.641,26 untuk Pit A1B Timur dan Rp. 1.896.376.705,18 untuk Pit A1B Barat.
