“…The wheel lathe process is carried out to minimise problems, namely the frequent careless operators in terms of safety. To maintain the condition of the lathe and make it usable, a scheduled maintenance and checking process must be carried out [6]. Lathes AMC 36-800/MA AN SHAN are performed using the help of lathes AMC 36-800/MA AN SHAN [7].…”

Maintenance emerges as a crucial intervention to ensure the sustained reliability of machinery. The AMC 36-800/MA AN SHAN lathe, a piece of equipment subject to extensive operational demands, frequently encounters breakdowns, thereby obstructing the seamless execution of maintenance activities for facilities. This investigation seeks to pinpoint the components responsible for the failures and malfunctions afflicting the lathe above. Employing the methodologies of Failure Mode and Effects Analysis (FMEA) and Fault Tree Analysis (FTA), this study successfully identifies the components at the epicentre of the machine's vulnerabilities. The analysis culminates in delineating critical components by calculating Risk Priority Numbers (RPN), unveiling a pivotal RPN value of 309.57. Moreover, it isolates two components whose failure modes surpass the critical RPN threshold: the Drive Motor and the Fixed Head. The genesis of these failures can be attributed to the escalating operational intensity, elevated engine temperatures, and a maintenance regimen that is both sporadically scheduled and suboptimal. Keywords: Lathe AMC 36-800/Ma AN Shan, Failure mode, FMEA, FTA, RPN

“…6 According to Ervianto, welding defects occur due to errors caused by a welding process that appears during welding inspections. 7 Weld defects can arise from several factors. Factors that cause welding defects include welders, where the welder plays a role in welding results.…”

The purpose of the study is to observe the Problem-Based Learning learning model; it is hoped that students, as prospective welding welders, can understand the types and forms of welding defects that arise to assess the quality of welding performed. This research was conducted on grade XI Las 2 students of SMKN 1 Udanawu using the classroom action research method (Classroom Action Research). The results of the research conducted obtained an increase in the average completeness results of students from the precycle, cycle I, and cycle II students of grade XI Las 2 SMKN 1 Udanawu, which initially only reached 30.2 in the precycle to 56.4 in cycle I and in cycle II to 81.3. This happens because, in practice-based learning, students only concentrate on practice and ignore theories related to welding defects. After Problem-Based Learning is carried out, students better understand the causes and effects of welding defects that arise. The factor that increases student understanding in cycles I and II is that learning is made in groups, so students are more active in identifying welding defects. In cycle II, students present the identification results so that students indirectly understand the material related to welding defects. From the increased learning outcomes, students can judge the welding quality performed.
