Kajian Ekonomi Pemilihan Alat Gali-Muat dan Angkut Baru atau Lama pada Penambangan Batu Gamping
Abstract
Abstract. The research results show that the actual production of the old excavator is 6,719.68 BCM/month and the old hauling equipment is 6,462.08 BCM/month, while the new excavator reaches 8,228.28 BCM/month and the new hauling equipment achieves 9,096.96 BCM/month. Furthermore, the calculated Present Worth Cost (PWC) of the old excavator is IDR15.012.042.960,28 per year, while the new excavator reaches IDR 23.331.547.748,72 per year. For hauling equipment, the PWC of the old dump truck is IDR 5.046.592.268,69 per year, while the estimated PWC of the new hauling equipment is IDR9.190.926.133,56per year. The Unit Production Cost (PUC) of the old excavator is IDR R17.499,09 /BCM, whereas the new excavator is IDR7.309,57/BCM. Meanwhile, the PUC of the old hauling equipment is IDR10.087,88/BCM, and the new hauling equipment is IDR 11.689,65. Based on technical and economic analyses, the old excavating and hauling equipment is unable to achieve the production target with lower unit costs; therefore, the use of new equipment is recommended. Abstrak. Hasil penelitian menunjukkan bahwa produksi aktual alat gali-muat Lama sebesar 6.719,68 BCM/bulan, dan produksi aktual alat angkut lama sebesar 6.462,08 BCM/bulan, lebih tinggi dibandingkan dengan alat gali-muat baru yang mencapai 8.228,28 BCM/bulan dan produksi aktual alat angkut baru sebesar 9.096,96 BCM/bulan. Selain itu, hasil perhitungan menunjukkan bahwa nilai PWC alat gali-muat lama sebesar Rp15.012.042.960,28 /tahun, sedangkan nilai PWC alat gali-muat baru sebesar Rp23.331.547.748,72 /tahun. Untuk alat angkut, nilai PWC dump truck lama sebesar Rp5.046.592.268,69 /tahun, sedangkan estimasi PWC alat angkut baru sebesar Rp9.190.926.133,56 /tahun Nilai PUC alat gali-muat lama sebesar Rp17.499,09 /BCM, sedangkan alat gali-muat baru sebesar Rp7.309,57 /BCM. Sementara itu, nilai PUC alat angkut lama sebesar Rp10.087,88 /BCM, dan alat angkut baru sebesar Rp11.689,65 /BCM. Berdasarkan hasil analisis teknis dan ekonomi, dapat disimpulkan bahwa penggunaan alat gali-muat dan alat angkut lama belum mampu mencapai target produksi dikarnakan kondisi alat yang sering rusak, sehingga penggunaan alat baru direkomendasikan.
