One of the functions of bioactive peptides is as an antioxidant. This study aims to characterize eel myofibril (Synbranchus bengalensis), determine the effect of papain enzyme ratio and hydrolysis time on eel myofibril protein hydrolysates, determine the antioxidant activity of eel myofibril hydrolysates by using DPPH and reducing power assay, and characterize the hydrolysate of myofibril proteins which have the best antioxidant activity. The results showed that eel myofibril protein contained moisture, fat, protein and ash of 85.91, 0.15, 0.14 and 12.78% respectively and contained the highest glutamic acid and lysine. Hydrolysates of eel myofibril proteins treated using various enzyme ratio and hydrolysis time had hydrolysates yields ranging from 3.53-9.68%, the value of hydrolysis degrees 5.20 - 16.193%, IC50 14.24 - 30.26 mg/mL for DPPH assay and absorbance 0.125 - 0.190 at a concentration of 5 mg/mL for reducing power assay. Hydrolysis eel myofibril protein using ratio papain 0.20:100 for 2 hours produced the highest antioxidant activities measuring by DPPH scavenging and reducing power iron. The hydrolysate had molecular weight approximately 19.51 kDa. Glutamic acid and lysine became the dominant amino acids of the hydrolysate.

The experimentation was done using randomized factorial design.In general, solvent type, shell to solvent ratio and temperature affected resin yield and its property. Based on the variance analysis results (α=0.05), the effect of temperature and shell to solvent ratio on resin yield was more evidential than solvent type.The higher the ratio of shell to solvent and the temperature, the resin yield was also increasing. The highest resin yield (7.69% or 75.32% based on potential mass of resin contained in Calophyllum shell) wasobtained at a shell to solvent ratio of 1:8 and a temperature of 50°C with methanol as solvent.The effect of process conditions was very noticeable on total phenol content of resin, while its acid value was only significantly affected by solvent type andshell to solvent ratio. An increase in shell to solvent ratio and temperature improved total phenol content of resin.The highest total phenol content (71.23 mg gallic acid equivalent/kg) was obtained at 1:8 of shell to solvent ratio and 30°C with methanol as solvent. Acid value of resin ranged from 112-145 mg KOH/g, and it positively contained saponins.Calophyllum fruit shell had thus great potential as a natural resin source.

The exploratory research method with observation approach was implemented in this research. The feasibility aspects to observed are market, technical, human resource and organization, environment and financial aspect for revenue sharing. The result showed that tapioca flour and mocaf flour were potential substitutes for wheat flour. Based on the availability of raw materials, mocaf flour has a minimum availability of 10.000 tons / year, therefore it had 29 tons/day to substituted wheat flour. This research designed the substitution of wheat flour were 5% of mocaf flour and 5% of tapioca flour. The feasibility study showed that the payback period (PBP) was 3 years and 6 months while Break Event Point (BEP) was 153.258.997 Kg/year.
