Abstract. PT Puspa Jaya Madiri is a company engaged in nonmetalic minerals mining, and has WIUP Andesite in Mekarsari Village, District Cikalong Kulon, Cianjur Regency, West Java Province. PT Puspa Jaya Madiri has also obtained a Decree of the Head of Investment and Licensing Board of Integrated West Java Province dated July 19, 2016. Based on a feasibility study that has been conducted, the amount of andesit reserves mined amounted to 3,448,806 BCM, with an overburden of 5,277,945 BCM. The mining activities is started by topsoil stripping, followed by overburden removal, and then andesite mining by explosion. In order to meet the target production, the conducted mining production applies 1 shift work with the duration of 8 hours of work plus 2 hours of overtime. The tools used for mining activities are excavator komatsu PC 400-8 4 units, dump trucks Komatsu HDD 255-5 4 to 5 units, and other supporting tools for supporting and processing andesite. The products that will be marketed are macadam I -125mm + 70mm, macadam II -70mm + 50mm size, split stone -50mm + 30mm, split-sized stone -30mm + 20mm, split-sized stone -20mm + 10mm, concrete sand -10mm + 5mm and sirtu sized -5mm. Based on the results of the cash flow analysis, the obtained value of NPV was Rp 88.285.513.810, IRR was 109,96%, and BP was 1,09 years. Therefore, based on the criteria, the project is reasonable to be conducted. Based on the sensitivity analysis, the project was not sensitive because when NPV value was 0, the production cost was 36,28% and the selling price was 23,80%.Keywords : Andesite and Overburden, Mining Technical Design, Investment Analysis, Discounted Cash Flow (DCF), and sensitivity analysis. Abstrak. PT Puspa Jaya Madiri adalah suatu perusahaan yang bergerak di bidang pertambangan mineral bukan logam, dan memiliki WIUP Andesit di Desa Mekarsari, Kecamatan Cikalong Kulon, Kabupaten Cianjur, Provinsi Jawa Barat. PT Puspa Jaya Madiri juga telah memperoleh Surat Keputusan Kepala Badan Penanaman Modal Dan Perijinan Terpadu Provinsi Jawa Barat tertanggal 19 Juli 2016. Berdasarkan kajian studi kelayakan yang telah dilakukan, jumlah cadangan andesit yang tertambang sebesar 3.448.806 BCM, dengan overburden sebesar 5.277.945 BCM. Metode penambangan yang diterapkan sesuai dengan kemajuan tambang yaitu side hill type quary dan dilanjutkan dengan pit type quary. Kegiatan penambangan dilakukan dengan urutan pengupasan tanah penutup, penggalian overburden (tanah urug), dan terakhir penambangan andesit dengan cara peledakkan. Produksi penambangan yang dilakukan untuk memenuhi pencapaian produksi diterapkan 1 shift kerja dengan durasi 8 jam kerja ditambah 2 jam lembur. Alat yang digunakan untuk kegiatan penambangan yaitu excavator komatsu PC 400-8 4 unit, dump truck Komatsu HDD 255-5 4 sampai 5 unit, dan kebutuhan alat penunjang lain untuk support dan pengolahan andesit. Produk yang akan dipasarkan yaitu makadam I berukuran -125mm +70mm, makadam II berukuran -70mm +50mm, batu split berukuran -50mm +30mm, batu split berukuran -30mm +20mm, batu split berukuran -20mm +10mm, pasir beton berukuran –10mm +5mm dan sirtu berukuran -5mm. Berdasarkan hasil kajian analisis aliran kas didapat nilai NPV yaitu Rp 88.285.513.810, IRR yaitu 109,96%, dan BP yaitu 1,09 tahun, maka berdasarkan kriteria tersebut proyek ini layak untuk dijalankan. Berdasarkan analisis sensitivitas menunjukkan bahwa proyek ini tidak sensitif, karena pada saat nilai NPV 0 kenaikan biaya produksi berada pada 36,28% dan harga jual 23,80%.Kata Kunci : Andesit dan Tanah Penutup, Rancangan Teknis Penambangan, Analisis Investasi, Discounted Cash Flow (DCF), dan analisis sensitivitas. |
