Abstract
PT Sugih Alamanugroho adalah perusahaan pertambangan batugamping yang berada di Yogyakarta. Endapan bahan galian daerah penelitian termasuk dalam Endapan Bahan Galian A berdasarkan klasifikasi menurut Spero Carras. Besar cadangan total yang dimiliki oleh PT. Sugih Alamanugroho adalah 5,000,000 m3. Dengan sasaran produksi sebesar 26,520 ton/tahun maka dapat dihitung umur tambang adalah mencapai 622 tahun. Berdasarkan pertimbangan kanaikan harga produk batugamping serta kenaikan biaya – biaya produksi, maka perhitungan aliran uang tunai dibatasi sampai 5 tahun. Untuk perhitungan aliran uang tunai di tahun – tahun berikutnya disesuaikan dengan kanaikan biaya produksi dan pendapatan. Tujuan dari perhitungan aliran uang tunai adalah untuk mengetahui besar investasi total di tahun ke-0, besarnya biaya operasi selama kegiatan penambangan, dan untuk mempertimbangkan layak atau tidak kegiatan penambangan dilakukan sesuai dengan nilai NPV, DCFROR, dan PBP dengan membandingkan dua macam struktur modal. a. Struktur modal 100% modal sendiri Nilai Net Present Value (NPV) Rp (1,809,878,801.02), Discounted Cash Flow Rate Of Return (DCFROR) 10%, dan Pay Back Period (PBP) 4.28 tahun. b. Struktur modal 60% modal sendiri dan 40% pinjaman Nilai Net Present Value (NPV) Rp 186,823,781.36, Discounted Cash Flow Rate Of Return (DCFROR) 14%, dan Pay Back Period (PBP) 4.19 tahun. Dengan melihat besarnya NPV, DCFROR, dan PBP masing-masing struktur modal, struktur modal 60% modal sendiri 40% pinjaman lebih layak untuk dipertimbangkan. PT Sugih Alamanugroho is a limestone mining company located in Yogyakarta. Deposition of mineral deposits research areas included in the Minerals A classification according to Spero Carras. Total reserves owned by PT. Sugih Alamanugroho is 5,000,000 m3. With a production target of 24,000 tonnes / year mine life, it can be calculated is reaching 687 years. Under consideration limestone product prices and increased costs of production, then the calculation of the cash flow is limited to 5 years. For the calculation of the cash flow in the year - next year adjusted by production costs and revenues. The purpose of the cash flow calculation is to determine the total investment in year 0, the cost of operations during mining operations, and to consider appropriate or not mining activity carried out in accordance with the value of NPV, DCFROR, and PBP by comparing the two kinds of capital structure. a. Capital structure of 100% equity Net Present Value (NPV) are (1,809,878,801.02), Discounted Cash Flow Rate Of Return (DCFROR) 10%, and Pay Back Period (PBP) 4.28 years. b.
