The objective of this research is to first get Standard Operational Procedure (SOP) of machining technique in Vocational High School (SMK), to get standard of tool, to get standard of time and standard amount of material for practicum of lathe machining technique in SMK to reach competent flat, facing, tapered lathe, lathe turning, screw lathe and lathe cartel. This research uses ADDIE (Analysis, Design, Development, Implementation and Evaluation). Participants of this study involve students and teachers from one public vocational school and one private SMK who both have accreditation A. SOP obtained consists of rational, objectives, competencies and procedures (work drawings, work flow, practice worksheets, job sheet, assessment sheet). Practical tools for flat turning competencies, face turning and tapered turning with lotan work drawings need 1 main tool, 1 cutting tool, 2 tools, 1 measuring tool, and 4 K3LH tools, while the lathe competence, screw lathe and lathe cartel with picture mandrel work requires 1 main tool, 4 cutting tools, 5 tools, 1 measuring instrument, and 4 K3LH tools. The standard practicum time to achieve flat turning competence, face turning and tapered lathe is 2x experiment is 423 minutes, while standard practicum time for achieving line plowing competence, screw lathe and lathe cartel with 2x experiment is 372 minutes. The practicum material used is st37 for a lottery image of ?25.4 ? 105 mm in size requiring an average of two workpieces and a mandrel image requiring materials of ?25.4 ? 65 mm in size which averages require two workpieces for each student. © Published under licence by IOP Publishing Ltd.
