Abstract

Fish gelatin hydrolysate is a well- known fish by-product that is high in protein content. It is produced from by-product waste from the fish processing industry, which includes fish skin, head, and bones. Gelatin hydrolysates have recently received much attention due to its high protein content and bioactivity, which includes antioxidant, antimicrobial and antihypertensive activities. The transformation of gelatin hydrolysate into nanoparticles is believed to increase its economic value. Furthermore, reduction into nano-size increases the absorption characteristic of this material. Here, fish gelatin hydrolysate nanoparticles are prepared for the first time using desolvation method. The effects of concentration of gelatin hydrolysate, pH of solution, and acetone concentration on nanoparticle size are determined. The prepared gelatin hydrolysate nanoparticles were found to have spherical shape with sizes varying from 300-400 nm with a mean size of 408 ± 11.4 nm, zeta potential of -16.4 ± 1.2 mV and PDI 0.203 ± 0.07. This study showed that concentration of gelatin hydrolysate, pH and concentration of solvent have significant effects on nanoparticle size. The gelatin hydrolysate nanoparticles can be applied in the pharmaceutical industry for the encapsulation of drugs to facilitate delivery to target sites.

Abstract

Banana peel is a waste material which accounts for one-third of a whole banana that has not been peeled. Unused banana peels will certainly increase the amount of waste produced. The amount of waste will continue to increase along with the increase in banana production. One solution is to use this waste as a raw material for chips production. Besides having the potential to reduce the amount of waste, this alternative can also increase the economic value of the banana peel so that it has the opportunity to be used as a business to increase people's income

Abstract

Tanggamus was the second largest coffee producer in Lampung Province. Ulubelu was one of the districs that had the highest coffee productivity in Tanggamus. Coffee price from farmer for green bean product was Rp 20.380 per kilogram while for red picking coffee bean was more expensive. Only a few farmer had SME to process coffee into its derivative products. This activity aims to make farmer aware of the importance of handling coffee and developing cofee derivative products. This activity was also purposed to increase coffee productivity for marketing through halal certification and improving coffee products quality. The method of this community service were preparation, survey, workshop post-harvest handling and production of coffee derivatives, training and assistance of halal certification. The result of this community service were farmer interest to developed derivative products of coffee, and there were 4 SME from 2 group of farmer that had received halal certification from this activity.
