Abstract

Vocational education in SMK aims to prepare students to become skilled labourers who are ready to enter the industrial world. Subjects such as lathe and milling machining play an important role in developing students' technical skills. This research aims to identify challenges in the implementation of Project-Based Learning (PjBL)-based sustainable project assignments in these subjects at SMKN 7 Serang City, as well as explore strategies to improve learning effectiveness. The research used a case study approach with qualitative descriptive method. Data was collected through direct observation and documentation. The results show that although the PjBL method helps students develop technical skills and soft skills, there are some obstacles. Challenges include lack of facilities, differences in students' ability to operate machines, and non-conformity with the ideal stages of PjBL, such as project design and schedule preparation which are still dominated by teachers. But in each stage of PjBL that is implemented, there are still some that are not in accordance with the application of PjBL. In addition, time management is the main obstacle in project completion. This study recommends increasing the role of students in all stages of PjBL, improving practical facilities, and strengthening supervision and guidance. In conclusion, optimal implementation of PjBL can improve technical skills and student readiness to face the world of work.

Abstract

The palm oil industry is an industry that produces palm oil. In palm oil processing, some stages have used machines. One of the machines in the palm oil industry is the distributing conveyor. The function of the distributing conveyor is to carry and distribute fresh fruit bunches from the fruit elevator to the digester. Maintenance is an activity carried out to repair or restore something that is damaged or experiencing problems. The main objective of this research is to analyze the component damage on the distributing conveyor machine and perform Corrective Maintenance on the machine through component replacement on the distributing conveyor machine. This research was conducted with a qualitative approach using the ex post facto method and the results were analyzed descriptively qualitatively. For data collection techniques, namely observation, literature study, and interviews. The results of the discussion are that when the Sprocket component on the distributing conveyor machine is damaged, signs such as vibration in the engine, abnormal sound, and decreased engine performance will appear and the effect when it is still forced to be used is to reduce the effectiveness of power transfer and the appearance of vibration or rumbling in the chain. In Corrective Maintenance actions there are several stages carried out, namely making component designs, modifying components, and replacing components. After the replacement of the new sprocket, the engine can function normally again, and the signs or disturbing effects have been resolved. Keeping machinery in good condition through timely Corrective Maintenance is critical to improving efficiency, productivity, and safety in industrial environments. Corrective Maintenance, although it tends to be more expensive, remains a part of the machine maintenance strategy to achieve optimal production results.
