Abstract

This study aims to determine the effect of the application of chitosan on fresh tilapia (Oreochromis niloticus) products as a natural preservative that can maintain the condition of fish with a longer shelf life. The method used in this study was experimental with three treatments, namely control treatment, 1% chitosan coating, and 1.5% chitosan coating. Data analysis was carried out through organoleptic tests with four parameters: color, aroma, texture, and taste of the tested tilapia. Observations were made for three consecutive days. The results showed that tilapia with 1.5% chitosan coating had better organoleptic parameter values than the other two test treatments. In conclusion, 1.5% of chitosan maintained the quality of tilapia with a longer shelf life. Keywords: Durability, Tilapia, Chitosan, Organoleptic

Abstract

Learning in the Kurikulum Merdeka is more focused on differentiated learning. There are three differentiated learning strategies, namely, content differentiation, process differentiation, and product differentiation. Learning in the Kurikulum Merdeka other than differentiation can also be supported by information technology. As technology develops, android application developers create android-based learning media which are then distributed through the google play store. However, none of them are in accordance with differentiated learning so it is necessary to develop an application that suits the needs of students and is in line with the Kurikulum Merdeka. The learning media development design used is the ADDIE model with 5 stages, namely Analysis, Design, Development, Implementation, Evaluation and produces products in the form of android-based differentiated mathematics learning media which contains material, comics, games, calculators and practice questions. The material used is single interest and compound interest (exponential on number elements) in accordance with the learning outcomes in phase E of the Kurikulum Merdeka. Based on implementation results, students feel comfortable with the application because user friendly.
