Pengembangan Dan Evaluasi Simulator Sistem Pgm-Fi Berbasis Arduino Sebagai Media Pembelajaran Praktik Di Training Center

Abstract

The Programmed Fuel Injection (PGM-FI) system requires practical learning media that can clearly display the relationship among sensors, controllers, and actuators. This study aimed to develop and evaluate an Arduino-based PGM-FI system simulator as a practical learning medium at the Training Center of PT Wahana Makmur Sejati Jatake. The study applied a research and development method using the ADDIE model and a mixed-methods approach. The stages included needs analysis, design, development, implementation, and evaluation. Three experts validated the product, and 30 trainees used it in a one-group pretest-posttest design. Data were collected through observation, interviews, expert validation, functional testing, learning achievement tests, and user-response questionnaires. The analyses included feasibility percentages, Cronbach’s Alpha, paired sample t-test, Normalized Gain, and Cohen’s d. The validation scores were 88.5% for media, 91.0% for content, and 86.0% for instructional design. Instrument reliability reached 0.842. The participants’ mean score increased from 58.33 to 84.67. The paired sample t-test produced t = -15.821, df = 29, and p = 0.000. The average N-Gain was 0.66, while Cohen’s d was 2.01. User responses reached 87.8%. These findings indicate that the simulator is highly feasible, effective, safe, and interactive. It supports diagnostic and troubleshooting practice for the PGM-FI system without using actual fuel.

Abstrak: Perkembangan sistem Programmed Fuel Injection (PGM-FI) menuntut media praktik yang mampu menampilkan hubungan sensor, pengendali, dan aktuator secara nyata. Penelitian ini bertujuan mengembangkan dan mengevaluasi simulator sistem PGM-FI berbasis Arduino sebagai media pembelajaran praktik di Training Center PT Wahana Makmur Sejati Jatake. Penelitian menggunakan metode research and development dengan model ADDIE dan pendekatan mixed methods. Tahapan penelitian mencakup analisis kebutuhan, perancangan, pengembangan, implementasi, dan evaluasi. Produk diuji oleh tiga validator ahli dan diimplementasikan kepada 30 peserta pelatihan melalui desain one-group pretest-posttest. Data dikumpulkan melalui observasi, wawancara, validasi ahli, uji fungsional, tes hasil belajar, serta angket respons pengguna. Analisis meliputi persentase kelayakan, Cronbach’s Alpha, paired sample t-test, Normalized Gain, dan Cohen’s d. Hasil validasi menunjukkan skor 88,5% pada aspek media, 91,0% pada aspek materi, dan 86,0% pada desain instruksional. Reliabilitas instrumen mencapai 0,842. Nilai rata-rata peserta meningkat dari 58,33 menjadi 84,67. Uji t menghasilkan t = -15,821, df = 29, dan p = 0,000. Rata-rata N-Gain sebesar 0,66 dengan Cohen’s d sebesar 2,01. Respons pengguna mencapai 87,8%. Temuan menunjukkan simulator sangat layak, efektif, aman, interaktif, dan dapat mendukung latihan diagnosis serta troubleshooting sistem PGM-FI tanpa menggunakan bahan bakar nyata.
