Prarancangan pabrik asam asetil salisilat (c9h8o4¬) menggunakan asam salisilat (c7h6o3¬), asetat anhidrida (c4h6o6), dan kalsium oksida (cao) sebagai bahan baku. proses produksi secara keseluruhan menggunakan proses sintesis handal-vega. kapasitas produksi sebesar 3.000 ton/tahun dengan waktu operasi 330 hari/tahun dan waktu 24 jam/hari. pabrik ini direncanakan dibangun di kawasan industri cilegon, cilegon, jawa barat, indonesia dengan luas area pabrik 20.125 m2. bentuk perusahaan yang direncanakan adalah perseroan terbatas (pt) dengan menggunakan metode struktur organisasi garis dan staf dan tenaga kerja sebanyak 99 orang. kebutuhan air untuk pabrik berasal dari pt krakatau tirta industri dengan laju alir 5.291,32 kg/jam, dan untuk kebutuhan listrik diperoleh dari generator dengan daya 614,77 kwh. hasil analisis ekonomi diperoleh sebagai berikut: 1. fixed capital investment (fci) = rp 140.552.768.331,- 2. working capital investment (wci) = rp 35.138.192.083,- 3. total capital investment (tci) = rp 175.690.960.414,- 4. total production cost (tpc) = rp 12.770.434.179.522,- 5. sales cost (sc) = rp 12.834.095.189.401,- 6. laba bersih = rp 34.805.414.211,- 7. pay out time (pot) = 3,8 tahun 8. break event point (bep) = 38,21 % 9. internal rate of return (irr) = 26,5 % berdasarkan studi kelayakan teknis dan ekonomis diatas, maka dapat disimpulkan bahwa prarancangan pabrik asam asetil salisilat ini layak untuk dilanjutkan ke tahap rancangan.

This preliminary design of acetyl salicylic acid (C9H8O4) plant uses salicylic acid (C7H6O3¬), acetate anhydride (C4H6O6), and calcium oxide (CaO) as raw materials. The overall production process uses a Handal-Vega synthesis process. The production capacity is 3.000 tons/year with an operating time of 330 working days/year and 24 hours/day. This factory is planned to be built in Cilegon Industrial Area, Cilegon, Jawa Barat, Indonesia with a factory area of 20.125 m2. The planned form of the company is a Limited Liability Company (PT) using the staff and line organizational structure method and a workforce of 99 people. The water requirement for the factory comes from PT Krakatau Tirta Industri with a flow rate of 5.291,32 kg/hour, and for electricity needs it is obtained from a generator with a power of 614,77 kWh. The results of the economic analysis are obtained as follows: 1. Fixed Capital Investment (FCI) = Rp 140.552.768.331,- 2. Working Capital Investment (WCI) = Rp 35.138.192.083,- 3. Total Capital Investment (TCI) = Rp 175.690.960.414,- 4. Total Production Cost (TPC) = Rp 12.770.434.179.522,- 5. Sales Cost (SC) = Rp 12.834.095.189.401,- 6. Net Profit = Rp 34.805.414.211,- 7. Pay Out Time (POT) = 3,8 years 8. Break Event Point (BEP) = 38,21 % 9. Internal Rate of Return (IRR) = 26,5 % Based on the technical and economic feasibility studies above, it can be concluded that the Preliminary Plant Design of the Acetyl Salicylic Acid Plant is feasible to proceed to the design stage.
