ANALISIS PERUBAHAN BERAT TERHADAP KENAIKAN SUHU CHIPO UNTUK BAHAN SMART PACKAGING MENGGUNAKAN TGA

Abstract

Indonesia has a larger ocean area than land, making it possible to develop a business in the field of fisheries. One of them is the development of shrimp and crab business. However, the business of crabs and shrimp were not separated from waste processed products. So it takes special handling to process crab and shrimp waste to be more economical value. Chipo is a mixture of chitosan and Polyvinyl alcohol. Chitosan is made from crab and shrimp. The purpose of this study was to determine the mass changes to temperature rise on chipo. The method used is by analysis of TGA (Thermal Gravimetric Analysis). The analyzed chipo samples were 20-22 mg. The result of TGA analysis showed that in Argon atmosphere chipo material lost mass of 9,964% when it reached 93,54oC. While in the atmosphere of oxygen up to 82.21oC temperature losing mass of 7.208 %. Thus, a thin layer of chipo don’t put at that temperature with atmospheric oxygen and argon conditions, in order to avoid mass loss of above.
