Abstract


The hypocotyls of Bruguiera gymnorrhiza have a high carbohydrate content, but have not been widely used as a staple food. An alternative use for Bruguiera gymnorrhiza hypocotyls is for the manufacture of starch. In addition to seeking new sources of starch for modern food industry. The research method used a completely randomized factorial design with three replicates and 2 treatment factors: NaHSO3 concentrations of 0.10%. 0.20%. 0.25% and 0.40% and temperatures of 40°C, 50°C and 60°C. Data analysis was carried out using SPSS version 16.0. The best treatment was determined using the De Garmo method. The results show that the best results were obtained from the treatment with a heating time of 5 minutes at 60 ° C with 0.40 % NaHSO3 concentration, producing 21.35 % amylose content, 64.30 % starch content, a viscosity of 40.33 %, 89.99 % solubility and 0.16 % monosaccharide content. a required investment of IRD. 88,550,000. The Net Present Value (NPV) analysis returned a figure of 90,011,325. The Internal Rate of Return (IRR) analysis gave a value of 46.81 %. The Payback Period (PP) analysis shows that the initial investment could be recouped within a period of 4 years and 3 months. The B/C ratio was 1.1. Based on the investment criteria analysis, it would be viable to establish this industry in West Seram District.
