Kegiatan inspeksi K3 untuk alat berat menjadi syarat utama bagi setiap kegiatan yang dilaksanakan pada sektor konstruksi. Kegiatan inspeksi meliputi jenis alat berat, jenis inspeksi yang dilakukan, pelaksana inspeksi K3 alat berat, hingga tahapan dari pelaksanaan inspeksi yang didalamnya terdapat proses pencatatan (recording) dan pelaporan (reporting). Proses inspeksi K3 alat berat dapat dilakukan dengan memanfaatkan bantuan teknologi berbasis Android yang melibatkan pengguna, yaitu operator, pelaksana inspeksi K3 alat berat, supervisor, dan manager. Penelitian ini menggunakan metode penelitian (research) dan pengembangan (development) untuk membuat suatu rancang bangun aplikasi inspeksi K3 alat berat di sektor konstruksi. Kata kunci: Inspeksi, alat berat, konstruksi Occupational Health and Safety (OHS) inspection activities for heavy equipment are the main requirements for every activity carried out in the construction sector. Inspection activities include the type of heavy equipment, the type of inspection carried out, the implementer of OHS inspection of heavy equipment, up to the stages of carrying out the inspection in which there is a recording and reporting process. The process of inspection of heavy equipment can be done by utilizing the help of Android-based technology that involves users, such as operators, inspector of heavy equipment, supervisors, and managers. This study uses research and development methods to create a design for OHS heavy equipment inspection applications in the construction sector. Key words: Inspection, heavy equipment, construction
