Pembuatan Soap Noodle dari Virgin Coconut Oil (VCO) Menggunakan Proses Saponifikasi dengan Kapasitas 450.000 Ton/Tahun dan Tugas Khusus Rancangan Keteknikan Detail Tangki Pencampuran

Abstract

The pre-designed factory for making soap noodles from virgin coconut oil (VCO) using a saponification reaction has a production capacity of 450.000 tons/year and operates for 330 days for 1 year. The main process in the pre-designed factory consists of four stages, namely the raw material preparation stage, stages of the process of saponification and purification of glycerin, the mixing stage, and the printing and packaging stage. The specific task that was completed was the detailed engineering design of the mixing tank. The mixing tank that has been designed has the following specifications:  Material of Construction : Carbon steel SA-285 grade C  Type : Vertical cylinder with a flat bottom and lid ellipsoidal  Tank volume : 24,3 m3  Tank diameter : 2,7 m  Tank height : 4,3 m  Plate thickness : 0,0064 m  Agitator type : Flat six-blade turbine  Stirrer diameter : 1,4 m  Stirrer length : 3,7 m  Number of baffles : 4 pieces The factory for making soap noodle from virgin coconut oil (VCO) is planned to be established in the Gresik Industrial Area, Gresik City, East Java, Indonesia with a required land area of 9.354 m2, the required workforce of 200 people with a form of a Limited Liability Company (PT) led by a main director with a line system organizational structure and staff. The results of the economic analysis of the soap noodle manufacturing factory from virgin coconut oil (VCO) using the saponification process are as follows: 1. Investment Capital : IDR 9.081.407.291.814,07 2. Production Cost : IDR 7.091.373.255.085,22 3. Net Profit : IDR 1.953.567.852.268,20 4. Profit Margin (PM) : 28.20% 5. Break Even Point (BEP) : 16.09% 6. Return on Investment (ROI) : 21.51% 7. Payment Period (POT) : 4.65 years 8. Network Return (RON) : 35.85% 9. Internal Rate of Return (IRR) : 25.46% From the results of the analysis, it was found that the factory for making soap noodles from virgin coconut oil (VCO) using the saponification process is feasible to establish.
