Abstract

Kegiatan pengabdian kepada Masyarakat dilaksanakan di SMK Negeri 11 Batam untuk mengenalkan gerbang logika sebagai dasar pembelajaran PLC kepada siswa jurusan Teknik Instalasi Tenaga Listrik. Kegiatan menggunakan metode ceramah, praktik, pre-test, post-test, dan kuesioner. Hasil kegiatan menunjukkan peningkatan pemahaman siswa, ditandai dengan kenaikan rata-rata nilai pre-test dari 62,20 menjadi 86,80 pada post-test. Hasil kuesioner mengindikasikan respons peserta yang positif, terutama pada aspek minat, manfaat, dan pelaksanaan kegiatan. Kedua hasil tersebut menunjukkan bahwa pembelajaran yang memadukan penjelasan materi dan praktik sangat efektif dalam meningkatkan pemahaman siswa terhadap gerbang logika dan PLC.

Abstract

 Steel plates are widely used in structural applications because of their ability to maintain structural form and their high tensile strength, which allows them to withstand significant loads in construction. This study presents the development of a monitoring system designed to measure strain in steel plate structures using strain gauge sensors. A theoretical comparison based on the elastic modulus of steel plates was employed to calculate stress, strain, and elongation under varying loads. The strain values recorded by the sensors are processed through an ESP32 microcontroller and displayed on an LCD screen for real-time observation. To enhance safety, the system is equipped with a buzzer and indicator lights that provide early warnings when the applied load exceeds a specified threshold. Experimental results show an average measurement error of only 2,98% compared to theoretical values, confirming the system’s accuracy and reliability. The proposed system offers a cost-effective and practical solution for infrastructure maintenance and supports the early detection of structural strain in steel plates.
