The Nata de Coco Quality Analysis for Making Fiber-Rich Instant Drink Powder

One of the potentials of coconut water that is widely developed in Indonesia is nata de coco. Nata de coco is the result of the fermentation of coconut water which is added by Acetobacter xylum. The research aim was to determine the quality of nata de coco as the basic material for making instant drink powder (IDP) which consists of natural flavors of orange, mango, and soursop. The step of the research was making a starter, making nata de coco, making IDP, and testing the quality of IDP (water content, specific gravity, taste, water solubility, and fiber). Data were analyzed using Tukey's significant difference test with a significance of 0.05%. The results showed that the water content of the IDP three flavors was less than 3%. Mango specific gratify is also higher but the orange flavor is the one of taste that people really like. The level of solubility in water shows that soursop is higher solubility. The fiber content of IDP orange is higher than mango and soursop. Therefore, nata de coco can be used as a raw material for making IDP

PENERAPAN MODEL PEMBELAJARAN PROBLEM SOLVING UNTUK MENINGKATKAN AKTIVITAS DAN HASIL BELAJAR SISWA MATERI SPLDV

This study aimed to determine the increase in student activity and learning outcomes in learning mathematics on the material of a two-variable system of linear equations. The background things are the low learning outcomes of students' mathematics. This is due to the use of an inappropriate teaching method approach. To overcome this, improvements can be made by applying a problem-solving learning model. This type of research is classroom action research (CAR). The subjects of this study were students of class X SMA Negeri 2 Jerebuu, totalling 14 people, consisting of 5 female students and 9 male students. Factors studied in the form of increased activity and student learning outcomes. Data collection methods used in this study were observation and test techniques. Data analysis used descriptive qualitative analysis with percentage technique. The results showed that the application of the problem-solving learning model could improve student activity and learning outcomes. Student learning activities in the first cycle obtained a total score of 29 with a percentage of 58% and were categorized quite well. Then it increased in the second cycle with the total score obtained being 43 and the percentage is 86% and categorized as very good. Student learning outcomes in the first cycle obtained an average of 70 with 50% of students achieving the Minimum Completeness Criteria (KKM). Then it increased in the second cycle with an average of 85.71 with 100% of students achieving KKM
