Abstract

PjBL-STEM is a project-based learning model integrated with Science, Technology, Engineering and Mathematics (STEM). The study developed a PjBL-STEM-based science module to improve creative thinking skills. The type of research and development used is ADDIE, namely analysis, design, development, implementation, evaluation. The feasibility of the module uses expert validation consisting of 3 material experts, 4 media experts, and 3 language experts. The module's practicality test by teachers consists of 4 teachers, and the readability test consists of 32 students. The module's effectiveness test uses a quasi-experiment with control and experimental classes. The control class is in VII C and the experimental class is in VII D. In each class there are 32 students with 16 females and 16 males. Based on the results of the study, it can be concluded that the average results of the validation of material experts (0.89), media experts (0.90), and language experts (0.86). Practicality by teachers (96%) and module readability (90%). The N-Gain value is 0.57 with a moderate category, which means that this module is quite effective in improving students' creative thinking skills.

Abstract

The purpose of this study was to determine the value of the modulus of elasticity and sugar content in Wajik snacks. Wajik is one of the traditional snacks that is popular with many people. The sweet and legit taste of wajik increases consumer interest in this product. This product is a semi-wet food made from glutinous rice, coconut milk and brown sugar. Coconut milk is a mandatory additional ingredient in making wajik, because the oil produced by coconut milk will produce a legit and savory taste. Coconut milk also produces fat in wajik. Elasticity was analyzed from 5 samples of wajik snacks and Analysis of sugar content (fructose, glucose, sucrose) was carried out using the high performance liquid chromatography (HPLC) method and total calorie analysis was carried out by adding calories from protein, fat, carbohydrate components or by calculation method. Protein content was analyzed using the Kjeldahl method, total fat analysis was carried out using the Weibull method, total carbohydrates were determined using the by difference method.

Abstract

Flavonoid, Fenol dan Kuinon adalah senyawa metabolit sekunder yang ditemukan pada ekstrak daun kemukus (Piper cubeba) yang memiliki fungsi sebagai agen bioaktif. Senyawa ini menunjukan aktivitas farmakologis termasuk sifat antioksidan, antimikroba, anti-inflamasi, dan antikanker. Tujuan penelitian ini adalah untuk memastikan komposisi fitokimia dalam ekstrak daun kemukus melalui skrining fitokimia.Hasil skrining fitokimia menunjukan bahwa ekstrak daun kemukus positif mengandung flavonoid, fenol, dan kuinon. Adanya senyawa sekunder tersebut ditandai dengan perubahan warna, flavonoid ditandai perubahan warna coklat muda, fenol perubahan warna gelap dan kuinon perubahan warna menjadi kuning tua. Temuan ini sesuai dengan penelitian lain yang menunjukan adanya metabolit bioaktif pada daun kemukus. Kehadiran senyawa ini meningkatkan potensi kemukus sebagai sumber bahan bioaktif alami yang dapat dikembangkan menjadi obat herbal
