Prarancangan pabrik carbon black dari pirolisis sampah plastik. proses produksi secara keseluruhan menggunakan proses furnace black. kapasitas produksi sebesar 12.000 ton/tahun dengan waktu operasi 330 hari/tahun dan waktu 24 jam/hari. pabrik ini direncanakan dibangun di dekat bengawan solo, lamongan, jawa timur, indonesia dengan luas area pabrik 13.765 m2. bentuk perusahaan yang direncanakan adalah perseroan terbatas (pt) dengan menggunakan metode struktur organisasi garis dan staf dan tenaga kerja sebanyak 116 orang. kebutuhan air untuk pabrik berasal dari sungai alas dengan laju alir 44.321,75 kg/jam, dan untuk kebutuhan listrik diperoleh dari generator dengan daya 2.185,73 kw. hasil analisis ekonomi diperoleh sebagai berikut: 1. fixed capital investment (fci) = rp 178.288.110.978,- 2. working capital investment (wci) = rp 19.809.790.109,- 3. total capital investment (tci) = rp 198.097.901.087,- 4. total biaya produksi (tpc) = rp 269.201.176.161,- 5. hasil penjualan (sc) = rp 388.608.654.034,- 6. laba bersih = rp 89.555.608.405,- 7. pay out time (pot) = 2 tahun 8. break event point (bep) = 32,35% 9. internal rate of return (irr) = 36,3% 10. rate of return (ror) = 45,21 % berdasarkan studi kelayakan teknis dan ekonomis diatas, maka dapat disimpulkan bahwa prarancangan pabrik carbon black ini layak untuk dilanjutkan ke tahap rancangan.

Preliminary Design of a Carbon Black Plant from Plastic Waste Pyrolysis. The overall production process uses the Furnace Black process. The production capacity is 12,000 tons/year, with an operational time of 330 days/year and 24 hours/day. This plant is planned to be built near the Bengawan Solo River, Lamongan, East Java, Indonesia, with a plant area of 13,765 m². The planned company structure is a Limited Liability Company (PT), using a line and staff organizational structure, with a workforce of 116 employees. Water requirements for the plant will be sourced from the Alas River at a flow rate of 44,321.75 kg/hour, and electricity needs will be met by a generator with a capacity of 2,185.73 kW. The economic analysis results are as follows: 1. Fixed Capital Investment (FCI) = Rp 178.288.110.978,- 2. Working Capital Investment (WCI) = Rp 19.809.790.109,- 3. Total Capital Investment (TCI) = Rp 198.097.901.087,- 4. Total Production Cost (TPC) = Rp 269.201.176.161,- 5. Sales Cost (SC) = Rp 388.608.654.034,- 6. Net Profit = Rp 89.555.608.405,- 7. Pay Out Time (POT) = 2 year 8. Break Event Point (BEP) = 32,35% 9. Internal Rate of Return (IRR) = 36,3% 10. Rate of Return (ROR) = 45,21% Based on the technical and economic feasibility studies above, it can be concluded that the preliminary design of the Carbon Black Plant is feasible to proceed to the design stage.
