Abstract

Chitosan is a biopolymer produced from the chitin deacetylation process that is widely present in the outer skin of crustacean animals such as shrimp and crabs. This study aims to determine the effect of temperature and reaction time on the deacetylation process and chitosan characterization analysis (yield, moisture content, ash content, and deacetylation degree). Crab shell crab with size of 100 mesh. The chitin found in the crab shell powder was isolated by deproteinization and demineralization processes. The resulting chitin is then transformed into chitosan by deacetylation process under operating conditions at 100 °C, 110 °C and 120 °C, 50% NaOH concentration, chitin mass ratio and NaOH volume 1:20 (b / v), stirring rate 150 rpm, and reaction time of 1 hour, 2 hours and 3 hours. The results showed that the higher the temperature and the duration of reaction time caused an increase in the degree of deacetylation and a decrease in yield and ash content, while the water content had no effect. Chitosan obtained has a yield of 38.14 - 60.36%, moisture content of 1.78 - 3.57%, ash content 0.75-1.75% and deacetylation degree 72,47 – 86,75%.Keywords: biopolymer, chitin, chitosan, deacetylation, deacetylation degree

Abstract

Pelalawan has several attractions, and Bono Waves in Ogis Beach Village Teluk Meranti Sub-district is one of them. However, these attractions are not supported by sufficient facilities, one of which is a residential resort. This design has a close connection with the resort destination in Ogis Beach that is with Coastal Architecture Approach. In addition, the design of tourist attraction area Ogis Beach Beach Bono will apply the concept of "Rhythmic Rising Waves" which is the main basic concept in the design. In this concept there are several applications of the design of the nature of waves, such as masses and roofs adapted from the nature of waves that have a low rhyming high. The color of the building is adapted from the color of the kampar river like the color of wood is brown. Then the circulation in the building that is created does not have a partition, so it can surprise people who see it. This design has a design that applies the principle of coastal architecture and the concept taken from the nature of the waves. By using some application of the concept, this design can minimize the negative influence gained from coastal tourism area ogis estuary bono. So this design provides benefits, both environmentally and to the design on the building itself.Keywords: Seaside Resort Ogis Muara Bono in Pelalawan with the Approach Coastal Architecture.
