Pembuatan Surfaktan Sodium Lignosulfonat dari Kulit Buah Markisa Menggunakan Proses Delignifikasi dan Proses Sulfonasi dengan Kapasitas Produksi 9000 Ton/Tahun dan Tugas Khusus Rancangan Keteknikan Detail Reaktor Delignifikasi

Abstract

The manufacture of sodium lignosulfonate surfactant from passion fruit peel using the delignification and sulfonation processes has a capacity of 9,000 tons/year and operates 330 days a year. The main process in this design consists of three stages, namely the raw material preparation stage, the delignification stage, and the sulfonation stage. At the delignification stage, a soda process was applied using sodium hydroxide as a cooking solution at a temperature of 90°C for 1.5 hours. In the sulfonation stage, the operation is carried out at a temperature of 90°C for 3 hours using sodium bisulfite as a sulfonation agent. The amount of passion fruit skin required to reach annual production capacity is 1,652.47 kg/hour. The factory is planned to be established in Asahan Regency, North Sumatra Province, with a total area of 24,000 m2.The planned form of company organization is a Limited Liability Company (PT) with a total of 145 employees. The results of the economic analysis of the surfactant manufacturing factory obtained are as follows: 1. Capital Investment (CI) = Rp484.767.625.379 2. Total Cost (TC) = Rp185.042.984.904 3. Profit Margin (PM) = 53,02% 4. Break Even Point (BEP) = 39,95% 5. Return on Investment (ROI) = 53,44% 6. Return on Network (RON) = 53,44% 7. Pay Out Time (POT) = 3 tahun 1 bulan 8. Internal Rate of Return (IRR) = 26,146% Based on economic analysis, it can be concluded that the design of a sodium lignosulfonate surfactant factory from passion fruit peel is feasible to be established.
