ABSTRAK
Prarancangan pabrik Furfural menggunakan bahan baku ampas tebu. Proses produksi secara keseluruhan menggunakan proses Supra Yield. Kapasitas produksi sebesar 35.000 ton/tahun dengan waktu operasi 330 hari/tahun dan waktu 24 jam/hari. Pabrik ini direncanakan dibangun di daerah Sunggal, Kabupaten Deli
Serdang, Provinsi Sumatera Utara dengan luas area 18.200 m2. Bahan baku ampas tebu diperoleh dari dua pabrik, yaitu PT Gula Sei Semayang, di Desa Mulyorejo, Kecamatan Sunggal, Kabupaten Deli Serdang dan PT Gula Kwala Madu di Desa Sidomulyo, Kecamatan Binjai, Kabupaten Langkat, Provinsi Sumatera Utara. Bentuk perusahaan yang direncanakan adalah Perseroan Terbatas (PT) dengan menggunakan metode struktur garis dan staf. Kebutuhan tenaga kerja untuk menjalankan perusahaan ini berjumlah 110 orang. Kebutuhan air untuk pabrik berasal dari Sungai Wampu dengan laju alir sebesar 97.818,64 kg/jam, dan untuk kebutuhan listrik diperoleh dari generator diesel dengan daya sebesar 21.756,37 kW. Hasil analisa ekonomi yang diperoleh adalah sebagai berikut:
1. Fixed Capital Investment = Rp 632.857.284.480,-
2. Working Capital Investment = Rp 158.214.321.120,-
3. Total Capital Investment = Rp 791.071.605.600,-
4. Total Production Cost = Rp 2.755.325.323.361,-
5. Sales Cost = Rp 3.191.414.604.660,-
6. Laba Bersih = Rp 327.066.960.975,-
7. Pay Out Time = 3,9 tahun (Metode linear)
8. Break Event Point = 40,03%
9. Internal Rate of Return = 25% (Metode cash flow)
10. Rate of Return = 41,34%
Berdasarkan studi kelayakan teknis dan ekonomis, maka dapat disimpulkan bahwa prarancangan pabrik Furfural ini layak untuk dilanjutkan ke tahap rancangan.

ABSTRACT The preliminary design of the Furfural plant utilizes bagasse as the raw material. The overall production process adopts the Supra Yield method. The production capacity is 35,000 tons/year, with an operational time of 330 days/year and 24 hours/day. The plant is planned to be built in the Sunggal area, Deli Serdang Regency, North Sumatra Province, with a total area of 18,200 m². The bagasse raw material is sourced from two factories: PT Gula Sei Semayang in Mulyorejo Village, Sunggal District, Deli Serdang Regency, and PT Gula Kwala Madu in Sidomulyo Village, Binjai District, Langkat Regency, North Sumatra Province. The proposed company structure is a Limited Liability Company (PT) with a line and staff organizational structure. The plant requires a total workforce of 110 employees. Water for the plant is sourced from the Wampu River with a flow rate of 97,818.64 kg/hour, while electricity needs are met by a diesel generator with a power capacity of 21,756.37 kW. The results of the economic analysis are as follows: 1. Fixed Capital Investment = Rp 632.857.284.480,- 2. Working Capital Investment = Rp 158.214.321.120,- 3. Total Capital Investment = Rp 791.071.605.600,- 4. Total Production Cost = Rp 2.755.325.323.361,- 5. Sales Revenue = Rp 3.191.414.604.660,- 6. Net Profit = Rp 327.066.960.975,- 7. Pay Out Time = 3,9 years (Linear method) 8. Break Even Point = 40,03% 9. Internal Rate of Return = 25% (Cash flow method) 10. Rate of Return = 41,34% Based on the technical and economic feasibility study, it can be concluded that the preliminary design of this Furfural plant is feasible to proceed to the design stage.
