Abstract

Edible film is one of the environmentally friendly packaging materials and not harmful to health because it is made up of natural ingredients such as proteins, lipids, and polysaccharides. In addition to environmentally friendly, the development of edible film on food packaging can provide better product quality, as it is made from natural ingredients that contain various natural chemical compounds that are beneficial and can be directly consumed. In this study prepared edible film derived from durian seed starch with the addition of soursop leaf extract. This research aimed at knowing the physical and chemical characteristics, and antioxidant activity of  the edible film. The type of research used is experiment methods. The results showed that the best research findings of the edible film were on the addition of 2 g soursop leaf extract and the physical characteristic was transmission of water vapor that was 1.70 g/m2. 24 hours, the chemical characteristics were water content that was 17.33% and activity of antioxidant that was 1.5875 mg/mL.

Abstract

Susu kelapa mengandung lemak dan protein serta kadar air yang tinggi sehingga menyebabkan produk ini mudah rusak. Untuk mendapatkan susu kelapa yang awet atau tidak mudah rusak, maka perlu ditambahkan bahan pengawet alami seperti vitamin E. Penelitian ini bertujuan untuk mengetahui ada atau tidaknya pengaruh penambahan vitamin E terhadap bilangan peroksida , pH, dan kadar protein dengan variasi waktu. Perubahan kualitas yang diamati berupa bilangan peroksida ditentukan dengan cara titrasi, pH ditentukan dengan pHmeter dan, kadar protein ditentukan dengan metode kjedhal dengan variasi waktu 0 (kontrol), 4, 8, dan 12 hari pada suhu 30C. Kualitas susu kelapa yang ditambah dengan vitamin E 100 IU dengan variasiwaktu 0 (kontrol), 4, 8, dan 12 hari masing-masing adalah: bilangan peroksida 0,3740; 0,4760; 0,6120; 0,6800 meq/kg , pH 6,1700; 5,9066; 4,7167 dan 4,0333, kadar protein 2,6657%; 2,3492%; 1,7163%; 0,8630%. Sedangkan kualitas susu kelapa tanpa penambahan vitamin E dengan variasiwaktu 0 (kontrol), 4, 8, dan 12 hari masing-masing adalah: bilangan peroksida 0,3400; 0,5440; 0,8840; 1,1560meq/kg, pH 6,1767; 4,6266; 3,1333; 2,2166, dan kadar protein 2,6561%; 1,5917%; 0,9876%; 0,4123%. Waktu maksimal penyimpanan terbaik untuk kualitas susu kelapa yang sesuai (bilangan peroksida dan pH dengan CODEX sedangkan kadar protein dengan SNI) adalah susu kelapa dengan penambahan vitamin E 100 IU sampai pada hari ke – 4.

Abstract

The goal of this study was to find out the effect of the implementation of science, technology, and society (STS) learning model by using concept maps toward students’ learning interest in Islamic Senior High School. Therefore, the study was carried out in queasy experiment design and the sample was taken through purposive sampling technique, which consists of two classes, namely XC as experiment class and XB as control one. After implementing those learning model and technique, the data was collected through questionnaire and documentation. Due to the statistic analysis, it was examined that the implementation of concept maps technique on experiment class has affected students’ interest in learning 81.45%, and it was categorized into good, in contrast, in control group it has affected students’ interest about 61.2% that was categorized into Fair. Similarity, the hypothesis testing by using Mann-Whitney test on the final questionnaire average score has revealed that the Zo (t-obtained) score was -5.74 and Z table score was -1.96 based on 5% significant standard, further, when Zo ≤-Z table, the null hypothesis was rejected and the alternative hypothesis was accepted. In conclusion, there was the significant effect of science, technology, and society (STS) learning model by using concept maps technique toward students’ learning interest in Hydrocarbon class in Islamic Senior High School of Islamic Boarding School Daarun Nahdhah Thawalib Bangkinang for the 2015/2016 academic year.Keywords : Science, Technology, Society (STS) teaching model, concept maps techniques, students’ learning Interest, and hydrocarbon.
