Abstract

Perkembangan teknologi yang pesat menimbulkan tantangan dalam bidang pendidikan, khususnya kemampuan peserta didik dalam mengamati dan menguji komponen elektronik seperti kapasitor serta menentukan kapasitansinya. Penelitian ini bertujuan untuk menganalisis kode dan angka pada kapasitor elektrolit tetap (fixed capacitor) melalui pengukuran dan pengamatan sistematis. Masalah penelitian difokuskan pada kesulitan identifikasi nilai kapasitansi kapasitor elektrolit dan penentuan parameter listriknya. Metode penelitian menggunakan pendekatan eksperimental dengan pengukuran langsung menggunakan multimeter digital terhadap lima sampel kapasitor elektrolit dengan nilai berbeda (10µF, 22µF, 33µF, 220µF, dan 470µF). Hasil penelitian menunjukkan bahwa kapasitor dengan kapasitas 10µF sampai 470µF merupakan jenis kapasitor polar dan non-polar yang mampu menyimpan muatan listrik dengan rentang tegangan 30mV-63.002V, arus 764.719mA-9.402A, dan beban 0.021W-470.001W. Analisis menunjukkan bahwa pengamatan kode angka pada badan kapasitor dapat menentukan kapasitansi dan parameter listrik secara efektif. Implikasi penelitian ini memberikan kontribusi pada pembelajaran komponen elektronik di SMK dan membantu teknisi dalam identifikasi kapasitor untuk perbaikan peralatan elektronik.

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.
