Abstract

Frozen shrimp activities of many companies in the Mahakam Delta region leaving the potential of shrimp waste that has not been maximally utilized. Application of appropriate technology capable to transforming shrimp waste into products of high economic value such as chitosan. Chitosan is produced through a sequence of processes, namely the extraction of chitin and deacetylation. In this research was review to deacetylation process as the function of temperature and concentration of alkali by measuring the degree of deacetylation. This research was used design of experiment of completely randomized design (CRD)-single factor. Chitin powder introduced into a reactor together with concentrated solution of alkali (50-80% w/w) on 1:20 ratio. The mixture was heated (80-120oC) with stirring. After that, the mixture was filtered and the solids neutralized and dried it. Degree of deacetylation of chitosan was analyzed using FTIR. The results showed that the optimum conditions of deacetylation process is achieved at a temperature of 100°C, alkali 70% (w/v) and a ratio 1:20 (w/v) with the degree of deacetylation 80.59%. Chitosan analysis with the parameters of ash content, moisture, and viscosity were found to be 0.01%, 6.99% and 3.6 cP, respectively. The chitosan product is suitable for industrial applications.

Abstract

Industry of sarung samarinda products original handicraft from Samarinda province. Except it, liquid wastes also given production from color processing. The wastes have a bad potency because of colour contain. In order to, it was needing process before as a garbage to environment. The main research has decrease colour compound of direct black 38 in liquid waste from fabrication. It was done after electrocoagulation process. The variable studied were voltage between 6-12 volt, space of electrode between 3-7 cm, time of process between 3-7 cm, time of process between 45-225 minutes in the batch reactor with capacity one litres. it made for get the best condition. The experiment result show wave length of 505 nm with spectrofotometry device. Based on product, the best of voltage electricity of 9 volt, time of process 180 minutes, and space of electrode 3 cm. In order to, the best result can decrease color concentration of 94,29%. That method could be one of alternative decrease of waste Sarung Samarinda Industry
