Pemanfaatan Limbah Cangkang Telur Ayam Teraktivasi Asam Jeruk Kalamansih (Citrofortunella microcarpa) Sebagai Biosorben Pewarna Rhodamin B
Get PDFRhodamine B merupakan zat pewarna sintetik yang paling umum digunakan dalam industri tekstil dan bersifat toxic. Penelitian ini bertujuan untuk memanfaatkan limbah cangkang telur ayam yang diaktivasi dengan asam dari jeruk Kalamansih (Citrofortunella microcarpa) sebagai biosorben pewarna rhodamine B. Cangkang telur ayam dihaluskan kemudian diayak menggunakan ayakan 100 mesh dan dikeringkan menggunakan oven pada suhu 105°C selama 2 jam. Biosorben lalu direndam menggunakan asam dari jeruk Kalamansih selama 24 jam untuk proses aktivasinya. Kinerja adsorpsi biosorben cangkang telur ayam dianalisis dengan menentukan persentase adsorpsi terhadap variasi massa biosorben: 0,5; 1,0; 1,5; 2,0; dan 2,5 g serta variasi konsentrasi rhodamine B (2, 4,6,8 dan 10 ppm) untuk melihat konsentrasi maksimum yang dapat diserap. Persentase adsorpsi tertinggi dihasilkan biosorben dengan massa 2,5g sebesar 64,10% dan konsentrasi maksimum rhodamine B yang dapat diserap adalah 10 ppm dengan persentase adsoropsi sebesar 40,72%. Hal ini membuktikan bahwa biosorben dari cangkang telur ayam yang diaktivasi oleh asam dari jeruk kalimansih mampu menyerap pewarna siktetik Rhodamine B

Get PDFThis research aims to determine the content of secondary metabolites and the effect of administration and effective dose of water extract of Plukenetia Volubilis (sacha inchi) leaves on triglyceride levels in diabetic mice. The research design is experimental with the pre-post test method and control group design. The samples used were 21 male white mice which were divided into 7 groups, namely the normal group, the positive control group (given glibenclamide), the negative group (only alloxan), and the treatment group (treated with sacha inchi leaf water extract) with different doses that is dosis dosis 0,26 g/kgBB, 0,525 g/kgBB, 0,525 g/kgBB (boiled water), 1,05 g/kgBB. Taking glucose and triglyceride data was checked 3 times within 10 days using a glucometer and lipid pro. The data analysis used the Analysis of Variance (ANOVA) method with the Statistical Package For Social Science (SPSS) Statistic IBM 23. This research began with testing of phytochemical compounds to determine secondary metabolism. Phytochemical test results with aqueous extract of Plukenetia Volubilis leaves contain tannins, alkaloids, saponins, and flavonoids. During 10 days of testing blood glucose and triglyceride levels on mice induced by alloxan, the effective dose was reduced on day 7 with a dose of 4 (1,05 g/kgBB). Based on the results of this research , it can be concluded that Plukenetia Volumbilis (Sacha Inchi) leaf water extract was detected to reduce blood glucose levels in mice and reduce blood triglyceride levels in mice for a certain time.

Internalisasi Nilai Keberanian Pada Proses Pembelajaran Untuk Membentuk Karakter Siswa Kelas V SDN 8 Kota Bengkulu
Get PDFThe value of courage is one of the principles in the Scout Dasadarma. This study aims to describe how teachers internalize the value of courage during learning and how students respond afterward. This qualitative descriptive research involved Scoutmasters, class 5C teachers, and class 5C students. Data were collected through observation, interviews, and documentation, with triangulation and member checks used to ensure credibility. Data analysis was conducted through reduction, presentation, and conclusion drawing. The findings show that the class 5C teacher implemented the three stages of value internalization: the Value Transformation Stage, the Value Transaction Stage, and the Value Trans-internalization Stage. The teacher applied character education using exemplary methods, habituation, advice, punishment, and emotional approaches to instill courage. These methods were integrated into the learning process to help shape student character. As a result, students of class 5C demonstrated positive behavioral changes and displayed courageous attitudes following the teacher’s efforts. In conclusion, the process of internalizing the value of courage in students was successfully carried out through structured character education approaches. The consistent application of exemplary behavior, routines, emotional connections, and disciplinary actions contributed to fostering courage in students in a meaningful and observable way

Genetic Variability and Heritability of Vegetative Growth Variables in 41 Cayenne Pepper Cultivars
Get PDFThis study aimed to estimate genetic and phenotypic variability, as well as heritability values, in 41 Cayenne pepper cultivars based on vegetative traits. The research was conducted from May to October 2024 at the Experimental Farm of the Faculty of Agriculture, University of Bengkulu, situated in Beringin Raya village, Bengkulu City, at an elevation of 10 m above sea level. A Randomised Complete Block Design (RCBD) was employed with a single factor consisting of 41 cultivars with three replications, each comprising 20 plants per replication. The results revealed a wide range of genetic variability for traits such as plant height, first dichotomous height, number of leaves, leaf area, leaf greenness, number of dichotomous points, canopy area, stem diameter, shoot fresh weight, and shoot dry weight. High phenotypic variability was observed across all evaluated traits. High heritability was found in the trait of first dichotomous height. Moderate heritability was observed for plant height, number of leaves, leaf greenness, number of dichotomous points, canopy area, shoot fresh weight, and shoot dry weight. Low heritability was detected in leaf area, stomatal density, and stem diameter
