Abstract

Penelitian ini bertujuan untuk menganalisis penerapan konsep aljabar linear, khususnya matriks, dalam penyelesaian rangkaian listrik sederhana dengan bantuan perangkat lunak MATLAB. Penelitian dilakukan dengan menerapkan hukum dasar kelistrikan yaitu Hukum Ohm serta Hukum Kirchhoff Arus (KCL) dan Hukum Kirchhoff Tegangan (KVL) untuk membentuk sistem persamaan linear yang merepresentasikan hubungan antara arus, tegangan, dan hambatan pada rangkaian listrik. Sistem persamaan yang diperoleh kemudian disusun dalam bentuk matriks AX = B sehingga dapat diselesaikan menggunakan metode Eliminasi Gauss dan Gauss–Jordan. Selain penyelesaian secara manual, proses perhitungan juga dilakukan dengan bantuan MATLAB untuk meningkatkan efisiensi dan akurasi hasil perhitungan. Hasil analisis menunjukkan bahwa representasi matriks dapat menyederhanakan proses penyelesaian sistem persamaan linear serta mempermudah penentuan nilai arus pada setiap cabang rangkaian. Penggunaan MATLAB juga membantu mempercepat proses komputasi dan meminimalkan kesalahan perhitungan. Dengan demikian, penerapan aljabar linear yang dipadukan dengan komputasi MATLAB memberikan pendekatan yang lebih sistematis dan efektif dalam analisis rangkaian listrik sederhana

Abstract

The current global environmental crisis demands a response that is not only ecological but also theological in nature. For Christians, the biblical teachings about God as Creator and Sustainer of the universe should serve as the foundation for shaping environmentally responsible behavior. This study aims to analyze the impact of students' understanding of biblical teachings about God on their environmental care behavior at the Electrical Engineering Education Study Program, Universitas Negeri Medan. This study employed a descriptive qualitative method with data collected through observation, semi-structured interviews, a questionnaire consisting of 15 statement items, and documentation. The research subjects were 5 students selected purposively. Data were analyzed using an interactive model comprising data reduction, data presentation, and conclusion drawing. The results indicate that all respondents demonstrated good theological understanding, with 100% stating they understand God as Creator, believe humans are responsible for caring for the environment, and feel that biblical teachings influence their environmental behavior. In terms of behavioral aspects, most respondents showed positive actions such as disposing of waste properly and maintaining campus cleanliness; however, consistency in reducing plastic use and conserving energy still needs improvement. This study implies the importance of strengthening applicative eco-theology education on campus to transform theological knowledge into consistent and sustainable character habituation.
