Abstract

Abstract. The growth of the construction sector and infrastructure projects such as roads, bridges, buildings and other public facilities in West Java can create a high demand for building materials, including andesit rocks. The high demand for andesit can provide economic and managerial opportunities to the andesit mines. PT Mitra Kartika Karya (PT MKK) is one of the mining companies that runs on andesit stone commodity located in Girimukti Village, Ciemas Prefecture, Sukabumi District, West Java Province with the potential of mined stone reserve andesit of 10.225.785 BCM. With that in mind, he needs an investment analysis before he does this mining activity. Net Present Value (NPV), Internal Rate of Return (IRR), and Pay Back Period (PBP). The Discounted Cash Flow Rate of Return (DCFROR) method determines whether or not a mining activity is valued from the value of money against time in a particular period by using the Weighted Average Cost of Capital (WACC) 12.13%. Based on the analysis of the Discounting Cash Flows (DCF) obtained NPV is Rp 35,635,539,524, IRR is 24.92% and PBP 5.55 years. This shows that PT MKK is economically viable because of the positive value of the NPV, the IRR is greater than the WACC and the PBP is less than the life of the mine. Further, sensitivity analysis is carried out to determine investment parameters that significantly influence the economy such as the value of the sale price and the cost of production. When the sale price drops more than 18.52%, and the cost of production rises more than 38.17%, then this project will be a loss.

Abstrak. Pertumbuhan sektor konstruksi dan proyek infrastruktur seperti jalan, jembatan, gedung-gedung serta fasilitas umum lainnya di Jawa Barat dapat menciptakan permintaan yang tinggi untuk bahan bangunan, termasuk batuan andesit. Tingginya permintaan andesit dapat memberikan peluang ekonomi dan pengelolaan yang bijak terhadap tambang andesit. PT Mitra Kartika Karya (PT MKK) merupakan salah satu perusahaan tambang yang berjalan pada komoditas batuan andesit yang terletak di Desa Girimukti, Kecamatan Ciemas, Kabupaten Sukabumi, Provinsi Jawa Barat dengan potensi batuan cadangan tertambang andesit sebesar 10.225.785 BCM. Dengan mempertimbangkan hal tersebut, maka diperlukannya analisis investasi sebelum dilakukannya kegiatan penambangan ini. Parameter analisis kelayakan investasi yang dipakai, yaitu Net Present Value (NPV), Internal Rate of Return (IRR), dan Pay Back Period (PBP). Metode Discounted Cash Flow Rate of Return (DCFROR) mengetahui layak atau tidaknya suatu kegiatan penambangan ini ditinjau dari nilai uang terhadap waktu dalam periode tertentu dengan menggunakan Weighted Average Cost of Capital (WACC) 12,13%. Berdasarkan hasil pengkajian didapatkan NPV aitu Rp 35.635.539.524, IRR yaitu 24,92% dan PBP 5,55 tahun. Hal ini menunjukan bahwa PT MKK layak secara ekonomi karena nilai NPV yang didapat positif, IRR lebih besar dari WACC dan PBP kurang dari umur tambang. Selanjutnya dilakukan analisis sensitivitas untuk menentukan parameter investasi yang secara signifikan berpengaruh terhadap keekonomian seperti nilai harga jual dan biaya produksi. Ketika harga jual menurun lebih dari 18,52% dan biaya produksi naik lebih dari 38,17%, maka proyek ini akan rugi.
