At PT. Senamas Energindo Mineral, I inspected articulated dump truck power trains and transmission components, and conducted engine inspections and diagnostics on dozers and motor graders.
At PT. United Tractors Tbk (Unit Scania), I assisted mechanics with field repairs and kept service logs and parts histories up to date.
I also scheduled preventive maintenance for buses based on usage intervals and HM/KM thresholds, helping ensure timely servicing in line with company standards.
In engineering projects at Universitas Gadjah Mada, I analyzed diesel genset damage, created a muffler, designed a PC-200-8 excavator starting system, and analyzed road vibration signals using Python, Phyphox, and Microsoft Excel.
