Protein hydrolysates contain bioactive peptides which have several function in order to maintain health and reduce the risk of disease. 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. Keywords: antioxidant, hydrolysates, myofibril, Synbranchus bengalensis, papain

The objective of this work is to extract the resin from Calophyllum fruit shell, and to investigate the effect of solvent type (ethanol and methanol), shell to solvent ratio (1:6 and 1:8)and temperature (30, 40 and 50°C) on resin yield and its property. 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.

Aloe vera and rosella flower has high antioxidants and has the potential as a functional drink. The purpose of this study was to analyze the antioxidant activity of aloe vera drink with the addition of various concentrations of rosella extract and stored for 21 days. The results showed that aloe vera drink with the addition of rosella flower calyx extract had a significant effect on antioxidant levels. The addition of rosella flower calyx extract at a concentration of 3% has the highest antioxidant, which is 58.12% after being stored for 21 days. Increasing the concentration of rosella flower calyx extract also significantly affected pH and total acid values. Aloe vera drink with the addition of 3% rosella extract after storage of 21 days had a total acid value of 6.6% and a pH value of 3.86. Different results are shown in the analysis of sensory tests, where the addition of rosella flower calyx extract to aloe vera drinks did not significantly affect the reception of panelists.

Proses hidrolisis bahan berselulosa tinggi memerlukan perlakuan pendahuluan untuk memisahkan lignin dan hemiselulosa dari selulosa, tetapi proses ini kurang efisien dan tidak ramah lingkungan. Enzim selulase adalah alternatif untuk menghidrolisa selulosa karena sifat kerja enzim yang spesifik dan tidak menghasilkan limbah yang berbahaya serta diharapkan mampu membantu memudahkan proses perlakuan pendahuluan. Bakteri selulolitik penghasil enzim selulase dapat diisolasi dari limbah pertanian yang banyak mengandung selulosa seperti limbah padat tapioka (onggok). Hasil penelitian menunjukkan bahwa 2 isolat yaitu TO4 dan TO5 merupakan isolat yang potensial menghasilkan selulase. Enzim selulase dari isolat TO4 dan TO5 memiliki aktivitas optimum pada pH 5 dan suhu 50°C dengan aktivitas enzim selulase sebesar 0,597 U/mg untuk TO4 dan 0,557 U/mg untuk TO5. Hasil uji kemampuan enzim dalam hidrolisis bahan berselulosa tinggi seperti bagas tebu menunjukkan bahwa enzim selulase dari isolat TO4 mampu menghidrolisis selulosa pada bagas tebu sebanyak 15,8% setelah direaksikan selama 120 jam.

Palm oil mill effluent (POME) is a liquid waste by product of fresh fruit bunches processing (FFB) in palm oil factory (POF). POME contains oil residue of 0.7% (from treated FFB). The purpose of this study was to convert oil residue of POME into biogasolin with the help of ultrasonic irradiation and catalytic cracking. The convertion was performed by reacting oil residue of POME with methanol in an esterification and transesterification reaction with the aid of ultrasonic irradiation. The reaction product was further reacted in the catalytic cracking reaction using zeolite-based catalysts (Ni/HZa and Mo-Ni/HZa). The overall reaction results were characterized using GCMS to determine the constituent components. The components found using Mo-Ni/HZa catalyst were 51.22% biogasoline and other products of kerosene and diesel as well as long chain methyl ester components, whereas using Ni/HZa catalyst was found a component equivalent to diesel at 2.44%. Keywords: biogasoline, ultrasonic irradiation, catalytic cracking, zeolite catalyst, POME
