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

Waste pollution in urban drainage systems remains a common environmental problem in urban areas, including Jalan Rela in Medan City. This study aims to analyze waste pollution in drainage culverts from the perspectives of environmental ecology and Christian ethics. The research used a descriptive qualitative approach through observation, interviews, and documentation. The results show that waste accumulation in drainage culverts is caused by low public awareness, inadequate drainage management, and limited concern for environmental cleanliness. These conditions disrupt water flow, cause flooding, create unpleasant odors, and increase environmental health risks. From an environmental ecology perspective, waste pollution reflects an imbalance in the ecosystem caused by human activities that exceed the environmental carrying capacity. Meanwhile, from the perspective of Christian ethics, littering contradicts humanity’s responsibility as stewards of God’s creation, as stated in Genesis 2:15. This study concludes that environmental problems require integrated solutions through drainage improvement, environmental education, community participation, and the strengthening of moral and spiritual values in caring for the environment.
