Prarancangan pabrik asam asetil salisilat (c9h8o4) menggunakan asam salisilat (c7h6o3) dan asetat anhidrida (c4h6o3) menggunakan proses sintesis kalsium oksida (cao) sebagai bahan baku. kapasitas produksi sebesar 6.500 ton/tahun dengan waktu operasi 330 hari/tahun dan waktu 24 jam/hari. pabrik ini direncanakan dibangun di kawasan industri kabil, batam, kepulauan riau, indonesia dengan luas area pabrik 26.127 m³. bentuk perusahaan yang direncanakan ialah perseroan terbatas (pt) dengan bentuk organisasi garis dan staf serta tenaga kerja sebanyak 100 orang. kebutuhan air pabrik berasal dari air waduk nongsa, batam, dengan laju alir 1.169,94 kg/jam, kebutuhan listrik diperoleh dari perusahaan listrik negara (pln) dengan cadangan listrik dari generator dengan daya 512,64 kw. hasil analisa ekonomi diperoleh sebagai berikut: 1. fixed capital investment (fci) = rp202.303.012.316,- 2. working capital investment (wci) = rp35.700.531.585,- 3. total capital investment (tci) = rp238.003.543.902,- 4. total production cost (tpc) = rp3.731.717.353.999,- 5. total income (ti) = rp3.833.635.735.626,- 6. laba bersih = rp76.438.782.470,- 7. pay out time (pot) = 3,3 tahun 8. break event point (bep) = 42,31% 9. internal rate of return (irr) = 31% berdasarkan studi kelayakan teknis dan ekonomis diatas, maka dapat disimpulkan bahwa prarancangan pabrik asam asetil salisilat ini layak untuk dilanjutkan ke tahap rancangan.

Preliminary design of an acetylsalicylic acid (C9H8O4) plant using salicylic acid (C7H6O3) and acetic anhydride (C4H6O3) via the synthesis process of calcium oxide (CaO) as raw materials. The production capacity is 6,500 tons/year, operating 330 days/year and 24 hours/day. This plant is planned to be constructed in the Kabil Industrial Estate, Batam, Riau Islands, Indonesia, with a plant land area of 26,127 m2. The proposed corporate form is a Limited Liability Company (PT) with a line-and-staff organizational structure, employing a total workforce of 100 people. The plant's water requirement is supplied from the Nongsa Reservoir, Batam, with a flow rate of 1,169.94 kg/hour. The power requirement is sourced from the State Electricity Company (PLN) with a backup generator capacity of 512.64 kW. The economic analysis yields the following results: 1. Fixed Capital Investment (FCI) = Rp202,303,012,316,- 2. Working Capital Investment (WCI) = Rp35,700,531,585,- 3. Total Capital Investment (TCI) = Rp238,003,543,902,- 4. Total Production Cost (TPC) = Rp3,731,717,358,999,- 5. Total Income (TI) = Rp3,833,635,735,626,- 6. Net Profit = Rp76,438,782,470,- 7. Pay Out Time (POT) = 3.3 years 8. Break Even Point (BEP) = 42.31% 9. Internal Rate of Return (IRR) = 31% Based on the technical and economic feasibility study above, it can be concluded that the Preliminary Design of this Acetylsalicylic Acid Plant is feasible to proceed to the detailed design phase.
