Prarancangan pabrik biohidrogen menggunakan molase menggunakan metode dark fermentation. kapasitas produksi sebesar 20.000 ton/tahun dengan waktu operasi 330 hari/tahun. pabrik ini direncanakan dibangun di kawasan industry medan, sumatera utara. bentuk perusahaan yang akan direncanakan adalah perseroan terbatas (pt) dengan bentuk organisasi yaitu garis dan staff dan tenaga kerja sebanyak 120 orang. pemenuhan kebutuhan air untuk pabrik berasal dari sungai sekitar pabrik dengan laju alir 761010,503 kg/jam. kebutuhan listrik diperoleh dari perusahaan listrik negara (pln) dan generator dengan daya 2719,221 kw. hasil analisis ekonomi diperoleh sebagai berikut. hasil analisa ekonomi yang diperoleh adalah : a. fixed capital investment = rp 358.004.815.382,36 b. working capital investment = rp 39.778.312.829,26 c. total capital investment = rp 397.783.128.202,62 d. total biaya produksi = rp 372.192.325.882,63 e. hasil penjualan (sc) = rp 508.419.914.811,68 f. laba bersih = rp 95.359.312.250,34 g. pay out time (pot) = 3,03 tahun h. break event point (bep) = 34,45 % i. internal rate of return = 17,94 % j. rate of return = 24 % berdasarkan studi kelayakan teknis dan ekonomis diatas, maka dapat disimpulkan bahwa prarancangan pabrik biohidrogen ini layak di lanjutkan ke tahap rancangan.

The biohydrogen factory design from molasses using dark fermentation method. Production capacity is 20,000 tons/year with operating time of 330 days/year. This factory is planned to be built in Medan industrial area, North Sumatra. The form of company that will be planned is a Limited Liability Company (PT) with an organizational form, namely line and staff and a workforce of 120 people. Meeting the air needs for the factory comes from the river with a flow rate of 761010.503 Kg/hour. Electricity needs are obtained from the State Electricity Company (PLN) and a generator with a power of 2719.221 kW. The results of the economic analysis are obtained as follows. The results of the economic analysis obtained are: a. Fixed Capital Investment (FCI) = Rp 358.004.815.382,36 b. Working Capital Investment (WCI) = Rp 39.778.312.829,26 c. Total Capital Investment (WCI) = Rp 397.783.128.202,62 d. Total Production Cost (TPC) = Rp 372.192.325.882,63 e. Sales Result (SC) = Rp 508.419.914.811,68 f. Net Profit = Rp 95.359.312.250,34 g. Pay Out Time (POT) = 3,03 years h. Break Event Point (BEP) = 34,45 % i. Internal Rate of Return (IRR) = 17,94 % j. Rate of Return (ROR) = 24 % Based on the technical and economic feasibility study above, it can be concluded that the biohydrogen factory design is feasible to proceed to the planning stage.
