Abstract

Bioplastics are biodegradable materials derived from natural polymers such as starch, cellulose, lignin, or chitosan and are considered sustainable alternatives to conventional plastics. In this study, chitosan-based bioplastics were prepared using chitosan extracted from fish scales and reinforced with alkali-treated ramie fibers. Chitosan was dissolved in 1% acetic acid at 50 °C for 4 h, followed by the addition of 5% citric acid and ramie fibers at various contents (15%, 20%, 25%, and 30% relative to chitosan mass), and stirred for an additional hour. The resulting bioplastics were characterized for tensile strength, elastic modulus, water absorption, and surface morphology using SEM. The results indicate that ramie fiber content significantly influences the mechanical and physical properties of the bioplastics. Increasing the fiber content generally enhances tensile strength and reduces water absorption; however, excessive fiber loading can lead to performance deterioration. The optimum formulation was achieved at 25% ramie fiber, exhibiting a tensile strength of 39.60 MPa, an elastic modulus of 43.35 MPa, and a reduction in water absorption of approximately 43% compared to fiber-free bioplastics, along with a more homogeneous surface structure. These findings demonstrate that ramie fiber reinforcement effectively improves the performance of chitosan-based bioplastics.

Abstract

English vocabulary mastery presents a significant challenge for nonformal education students characterized by heterogeneous backgrounds and limited face-to-face instructional time. This study explores the effectiveness of gamified vocabulary challenges through WhatsApp in improving vocabulary mastery among Grade XI students at PKBM Arrohmah Demak Package C program. Employing a pre-experimental design with one-group pretest-posttest, the research involved 40 students participating in a two-week gamification program with structured daily and weekly tasks. Data were collected through standardized vocabulary tests and participation tracking via WhatsApp platform. Analysis using paired sample t-test and Pearson correlation revealed significant improvement in mean scores from 56.2 to 74.8 with participation rates reaching 87.5%. The multidimensional assessment system measured timeliness, completeness, accuracy, and creativity with an overall achievement of 77.4%. A strong positive correlation was identified between participation levels and learning achievement. Findings confirm that integrating gamification and mobile learning through WhatsApp effectively enhances vocabulary mastery in nonformal education contexts. This platform offers high accessibility and flexibility suitable for adult learner characteristics. Despite its effectiveness, challenges such as limited internet access and low student creativity require attention in future digital learning implementations.

Abstract

Transformator merupakan komponen vital dalam sistem tenaga listrik yang berperan dalam proses penyaluran energi dari pembangkit hingga ke konsumen. Keandalan transformator sangat dipengaruhi oleh pelaksanaan pemeliharaan yang terencana dan berkala. Penelitian ini bertujuan untuk menganalisis efektivitas pelaksanaan pemeliharaan dua tahunan Transformator 1 di Gardu Induk Kenjeran 150 kV dalam menunjang keandalan sistem tenaga listrik. Metode penelitian yang digunakan adalah pendekatan kuantitatif deskriptif melalui pengumpulan data hasil pengujian teknis dan evaluasi kesesuaian terhadap standar yang berlaku. Pengujian meliputi Breakdown Voltage (BDV) minyak isolasi, tahanan isolasi, sistem pentanahan, serta pemeriksaan sistem proteksi dan peralatan pendukung lainnya. Data yang diperoleh dianalisis dengan membandingkan hasil pengukuran terhadap standar IEEE dan Surat Keputusan Direksi (SK DIR) PT PLN. Hasil penelitian menunjukkan bahwa seluruh parameter pengujian berada dalam batas standar yang dipersyaratkan, sehingga transformator dinyatakan dalam kondisi layak operasi dan memiliki tingkat keandalan yang baik untuk mendukung kontinuitas pasokan tenaga listrik.

Abstract

Community service has been carried out in RW 12 Kel. Merjosari Malang to increase the potential and participation of the community in health environment. The increase in the number of Covid-19 patients in Malang Raya, about 3,378 people, presents that the Covid-19 virus has increased drastically both number of patients confirmed positive and patients who died. The problems faced by partners are not understanding the Covid-19 disease, weak resources, limited funds, and difficulty accessing information. The method is socialization by conducting discussions, optimizing citizen resources, monitoring and evaluation. The result is conducting discussions, developing resources, providing training, providing counseling and assistance. Citizen involvement is to provide a place to install spraying equipment, maintain spraying facilities, provide a place to conduct training, provide human resources ready to be trained voluntarily. Citizens' anxiety and restlessness were slightly reduced by increased community understanding. Citizens give a positive assessment of service. This is proven by the percentage of residents giving a positive rating on average 95.68%, consisting of 95.33% giving a positive response, and 4.67% giving a negative response.
