Abstract

Occupational safety and health (OSH) is an important aspect of industrial activities, particularly in the transportation of hazardous and toxic waste (B3), which poses high potential risks to workers, the environment, and the surrounding community. PT.XYZ, as a hazardous waste transportation service company, faces various potential hazards at each stage of its operational process, including vehicle preparation, loading, transportation to the destination, unloading, as well as administration and housekeeping activities. This study aims to identify potential hazards, analyze the level of occupational safety and health risks, and formulate risk control recommendations in the hazardous waste transportation process at PT.XYZ. The research method used in this study is descriptive-analytical research with qualitative and quantitative approaches. Hazard identification was carried out using the Hazard and Operability Study (HAZOP) method based on field observations, interviews, and documentation studies. Risk level assessment was conducted using the Risk Matrix method by applying likelihood and severity parameters to classify risks into low, medium, high, and extreme categories. The results show that there are 20 potential hazards identified across all stages of the hazardous waste transportation process. The risk level recapitulation indicates that high and medium risk categories each account for 45%, extreme risk accounts for 10%, and no risks fall into the low category. Extreme risks were found during the transportation stage to the destination, particularly those related to driver fatigue and uncontrolled vehicle speed. Based on these findings, risk control recommendations were formulated using a risk control hierarchy approach, including administrative controls, engineering controls, and the use of personal protective equipment. The implementation of these recommendations is expected to reduce OSH risk levels and improve occupational safety and health performance in the hazardous waste transportation process at PT.XYZ.

Abstract

Kegiatan pengabdian masyarakat ini bertujuan untuk meningkatkan kreativitas dan keterampilan teknologi siswa jenjang SD, SMP, dan SMA melalui penerapan mikrokontroler dalam lomba robotika berbasis Lego sebagai respon terhadap dominasi pendekatan teoritis dalam pembelajaran teknologi saat ini. Menggunakan pendekatan deskriptif kuantitatif dengan desain Project -Based Learning (PjBL), kegiatan ini melibatkan 70 siswa di Kota Medan yang mengikuti tahapan pelatihan materi, praktik perakitan pemrograman, hingga kompetisi pada 20 Februari 2026. Hasil evaluasi menunjukkan peningkatan signifikan pada kompetisi siswa dengan capaian tertinggi pada kreativitas desain robot (75%) dan logika (70%), meskipun aspel algotitma pemrograman dasar masih menjadi tantangan dengan tingkat pemahaman sebesar (58%). Pelaksanaan kegiatan memperoleh respons sangat positif dengan tingkat kepuasan tertinggi pada kejelasan alur kegiatan (90%) dan kualitas perangkat (88%). Secara keseluruhan, integrasi mikrokontroler melalui lomba robotika berbasis Lego terbukti efektif dalam mengembangkan pemahaman sistem kendali, kemampuan problem solving, dan kolaborasi tim siswa guna menghadapi tantangan teknologi masa depan.
