The document describes the process of making parts for a motorcycle undertaken by Diky Setiawan at SMK TUNAS BANGSA TAWANGSARI in 2012. This included drilling an iron plate for a disc mount, using a 50mm metal lathe to make truck axles, welding a connecting plate, drilling holes in a crankcase using drilling machines, and tapping threads in an engine block using a hand screw tap. It then provides details on the time taken, number of people involved, and notes on each task. The document concludes that the two month training provided valuable experience that couldn't be gained elsewhere.
