Glucosamine is useful for overcoming joint disease or osteoarthritis. Glucosamine can be produced through synthesis involving carbon and amine. Carbon can come from plant derivatives that contain sugar, like coconut sap. While the amine branch can be derived from ammonium sulphate. This study aims to determine the effect of ammonium sulphate added as a precursor in the process of synthesizing glucosamine from coconut sap towards physiochemical characteristics of glucosamine. The research used a one-factor-randomized design with addition of six levels of ammonium sulphate, that are 1,5 M; 2M; 2,5 M; 3 M; 3,5 M and 4 M. The characterisation includes the glucosamine concentration, pH, solubility, colour, and loss on drying (LOD). The best treatment was selected by using the TOPSIS method. The results showed that the best treatment was the addition of a 3.5 M ammonium sulphate precursor compound which had a glucosamine content of 801.67 ppm; yield of 1.603%; pH 4.79; and LOD of 0.837%. The precursor concentration had significant effects on the yield of glucosamine synthesised from coconut sap. The higher of glucosamine content and the resulting yield indicate the efficiency of the treatment applied to the sample is higher.

Nipa (Nypa fruticans Wurmb.) belongs to the Arecaceae family, covering 30% of over 4 million ha of mangrove forest in Indonesia. The most valuable part of nipa is the fruits for food, drink, handicrafts, and medicine, leaving empty fruit bunches as waste. The empty fruit bunch waste reaches 75% of the total weight of nipa fruit, producing approximately 6 Mt/ha or over 6 million Mt in a year. Nipa empty fruit bunches (EFB) are biomass containing 27.3% lignin, 36.1% cellulose, and 21.8% hemicellulose. Due to Indonesia’s increasing nipa fruit harvesting, managing and finding a suitable solution to overcome waste issues is essential. In the present review, nipa EFB’s physical and chemical properties were found suitable as a biomass energy source. Nipa’s EFB energy recovery was potentially generated from direct combustion, pyrolysis, and briquette making. The harvesting challenge and emission from direct combustion or pyrolysis process limit the nipa utilization. Education and technology dissemination is required for the coastal communities to assist in utilizing nipa.

This study aimed to determine the optimal temperature and duration of freezing during the freezing process of VCO. The experiment used optimization method of Response Surface Methodology (RSM) with 2 factors and 4 responses. The first factor was freezing temperature with temperature variations of -23, -28, and -33ÂºC. The second factor was the duration of freezing for 44, 48 and 52 hours. The response variables measured were refractive index, FFA, moisture content, and rendemen. These data were formulated by using Design Expert 7.5 Free Trial software. According to these factors and responses, 13 treatments were obtained. The best treatment results followed by organoleptic tests using the hedonic scale (color, aroma, and taste) carried out by 30 semi-trained panelists. Organoleptic data were analyzed by Friedman test (Î±=0.05). Based on the results of experiments that had been carried out, the right model for the response of refractive index, water content, and rendemen was quadratic, while the FFA response had linear model. The temperature factor significantly influenced the response of refractive index, FFA, moisture content, and rendemen. The freezing time factor did not significantly influence the response of refractive index, FFA, moisture content, and rendemen. The best treatment result was obtained at freezing temperatures of -32.474ÂºC for 48.081 hours. The best treatment produces 31.42% of rendemen, 1.45113 of refractive index, 0.12% of water content, and 0.058% of FFA. The assessment of respondents on VCO for color parameters and taste could be accepted by consumers, while aroma parameters could not be accepted by consumers. For the further research on products that had been made should be immediately conducted an organoleptic test, thus there was no change of aroma on VCO.
