Abstract

Pemeliharaan rutin seperti Climb Up Inspection (CUI) penting untuk menjaga keandalan penyaluran sistem tenaga transmisi di PT. PLN (Persero) UPT Malang. Untuk memastikan bahwa komponen penting seperti insulator berada dalam kondisi normal dan baik. Jika terjadi masalah dengan aliran listrik, komponen harus diganti segera untuk menghindari masalah yang memengaruhi keandalan sistem. Seringkali ditemukan anomali bahwa hasil foto yang menunjukkan flashover pada insulator. Karena permukaan insulator dibebani oleh medan listrik yang lebih besar daripada kapasitas ketahanan elektriknya, terjadi kegagalan isolasi. Ini disebut sebagai flashover. Tujuan dari penelitian ini adalah untuk mengembangkan sebuah aplikasi yang mampu mengidentifikasi gambar insulator yang telah mengalami flashover. Dengan menggunakan pengolahan gambar digital, proses segmentasi dan ekstraksi ciri dilakukan pada citra. Pengolahan gambar seperti segmentasi, ekstraksi, dan identifikasi gambar dilakukan dengan program MatLab. Dengan menggunakan active contour dan luas rasio citra insulator normal dengan citra insulator flashover. Kategori insulator diklasifikasikan menjadi rendah, sedang, dan tinggi menggunakan metode pohon keputusan.  Hasil penelitian yang dilakukan menggunakan metode pohon keputusan menunjukkan bahwa kategori rendah dengan rasio x1 kurang dari 0,029958, x1 lebih dari 0,029958, dan x1 lebih dari 0.109648 dianggap sebagai kategori sedang dan tinggi, masing-masing dengan akurasi 80%. Aplikasi ini dapat membantu personel di lapangan mengidentifikasi gambar insulator flashover, yang memungkinkan mereka untuk menangani anomali dan menjaga keandalan listrik.

Abstract

In the current digital era, logical thinking skills and technological understanding are increasingly essential for vocational high school (SMK) students preparing to enter a technology-driven workforce. This community service program aimed to strengthen students’ logical thinking skills through STEM-based learning activities focused on the configuration and programming of line follower robots. The program was conducted over one month and comprised three stages: focus group discussion with school partners, development of instructional materials, and training sessions. The training involved 17 students. Participants were introduced to fundamental concepts of line follower robots, including basic logic, sensors, and programming principles, and then applied this knowledge through practical tasks. Evaluation results showed that 76% of students expressed increased interest in further learning robotics, while all participants (100%) successfully completed the assigned task of programming the robot to navigate from the starting point to the finish line. These findings indicate that robotics-based learning effectively supports the program’s objective of enhancing logical thinking while simultaneously increasing students’ engagement with STEM concepts. By integrating theoretical explanations with direct practice, the line follower robot served as an accessible and meaningful medium for translating abstract logical reasoning into concrete technological applications. The main contribution of this community service activity lies in offering an applied STEM learning model for vocational high schools, particularly in contexts with limited prior exposure to robotics. This program provides a practical reference for integrating educational robotics into SMK learning environments to strengthen logical reasoning, technical competence, and students’ motivation to pursue STEM-related fields.
