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. Capital structure of 60% equity and 40% debt
Net Present Value (NPV) are 186,823,781.36, Discounted Cash Flow Rate
Of Return (DCFROR) 14%, and Pay Back Period (PBP) 4.19 years.
By looking at the magnitude of NPV, DCFROR, and PBP each capital
structure, capital structure of 60% equity 40% more loans eligible for
consideration.
