Abstract

Pengembangan bioplastik sebagai kemasan merupakan solusi alternatif dalam mengatasi permasalahan lingkungan. Kemasan bioplastik dengan penambahan minyak atsiri sebagai antioksidan dapat menghambat terjadinya oksidasi sehingga dapat meningkatkan daya simpan suatu produk. Pati digunakan pada penelitian ini sebagai matriks penyusun bioplastik yang berasal dari bonggol jagung dengan penambahan gliserol sebagai plasticizer dan carboxymetyl cellulose (CMC) sebagai filler serta ekstrak jahe, jeruk nipis dan cengkeh sebagai zat antioksidan. Penelitian ini bertujuan untuk menentukan pengaruh konsentrasi ekstrak jahe, jeruk nipis dan cengkeh terhadap sifat kuat tarik, sifat water absorption, sifat biodegradabilitas, dan pengaplikasiannya pada buah dan sayur. Proses pembuatan bioplastik dilakukan menggunakan metode casting yaitu dengan melarutkan pati bonggol jagung dalam aquades dan dipanaskan pada suhu 70°C, kemudian ditambahkan ekstrak jahe, jeruk nipis dan cengkeh dengan variabel 0 (tanpa antioksidan), 5, 10 dan15% dari volume pati dengan penambahan gliserol dan CMC sampai homogen. Selanjutnya larutan dituang dalam cetakan dan dikeringkan. Dari hasil pengujian bioplastik diperoleh nilai water absorption, biodegradabilitas, kuat tarik yang paling baik yaitu pada penambahan ekstrak jahe 15% yaitu sebesar 26,02 %, 96,31%, 11,96 Mpa. Sedangkan untuk kemampuan antioksidan yang baik dengan penambahan ekstrak cengkeh 15% yang memiliki nilai IC50 sebesar 31,21 ppm.

Abstract

This study aims to determine the extent to which the active learning method impacts on increasing student learning motivation in Islamic Religious Education subjects. The subjects of this study involved class XIIA students at SMA NU 05 Brangsong. The purpose of this study was to improve scientific understanding in the field of education, especially in terms of the application of active learning methods. This research was conducted directly in the field using a descriptive qualitative approach. The methods used in data collection included interviews, observation, and documentation. Based on the results of the research data analysis, it can be concluded that efforts to increase learning motivation in Islamic Religious Education subjects for class XIIA students at SMA NU 05 Brangsong through active learning methods include the application of discussion methods. Student learning motivation for Islamic Religious Education subjects consists of two types, namely intrinsic and extrinsic motivation. Intrinsic motivation includes competition among students to be the best in academic terms, the ability to complete and submit assignments on time, and student activeness in the learning process. Meanwhile, extrinsic motivation includes the awarding of grades, the existence of rewards and punishments, the existence of a ranking system in the class, and the application of various learning methods.

Abstract

Indonesia has significant potential in dairy cattle production, one example being in Dusun Tepus, Ngantru Village, Ngantang Subdistrict, Malang Regency. The business group “Mustarika Jaya Makmur” consists of dairy farmers producing fresh milk. Previously, the State Polytechnic of Malang (Polinema) provided solutions in the form of training on supply chain management, milk processing, and the application of production calculation tools to support efficiency. Considering the business potential of mozzarella cheese, the group increased its production capacity to 50 liters of fresh milk on a pilot scale to initiate the “Kampung Kedju” program, aimed at improving the villagers’ livelihoods. This Community Service Program (PPM) is expected to provide solutions through production enhancement, assistance in the use of equipment in accordance with standard operating procedures (SOP), and the implementation of Good Manufacturing Practices (GMP) in cheese production. The expected outputs include improved partner capacity, scientific publications, and copyright registration of a HACCP guideline.

Abstract

Background: The rapid development of technology presents challenges in electronics education, particularly related to students’ ability to observe, identify, and test electronic components such as transistors through practical experiments. Objective: This study aims to systematically observe and measure transistor characteristics by identifying codes on the transistor body, determining voltage parameters, and analyzing LED load behavior when a transistor operates as a switch. Methods: The research employed an experimental approach using direct electrical measurements. A BC547 transistor was tested by applying incremental voltage inputs at the base terminal ranging from 2 Vpp to 4 Vpp (2, 2.5, 3, 3.5, and 4 Vpp). Measurements were conducted using a multimeter, power supply, and supporting circuit components under open-switch and closed-switch configurations. Results: In the closed-switch configuration, a voltage of 2 Vpp produced 0 A current with the LED off, while 2.5 Vpp resulted in 0 A current with dim illumination. Voltage inputs between 3–4 Vpp generated currents ranging from 0.02–0.12 A, causing the LED to illuminate brightly. In the open-switch configuration, all voltage levels resulted in 0 A current and the LED remained off, confirming switching behavior. Conclusion: The findings confirm that the BC547 transistor base terminal effectively functions as an electronic switch and amplifier. This study contributes to basic electronics learning by providing a clear, measurement-based experimental procedure and supports practical understanding for students and technicians in transistor identification and application.
