Abstract

Metode pengelasan SMAW digunakan secara luas dalam industri untuk menggabungkan material logam dengan kekuatan yang tinggi. Namun, pengelasan SMAW dapat menghasilkan cacat seperti porositas, retak, dan pengotoran yang dapat mempengaruhi kekuatan dan keandalan sambungan las. Penelitian ini bertujuan untuk menginvestigasi pengaruh ketebalan root face dan polaritas terhadap defect pada tembusan hasil pengelasan SMAW (Shielded Metal Arc Welding) dengan kuat arus ideal. Adapun Metode penelitian yang digunakan pada penelitian ini yaitu metode eksperimen dengan acuan uji AWS D1.1. Teknik pengumpulan datanya dengan melakukan pengujian pelat menggunakan cairan dye penetrant test dengan waktu yang dibutuhkan selama 40 menit setiap spesimen. Hasil penelitian menunjukkan bahwa ketebalan root face yang optimal dapat mengurangi terbentuknya defect pada tembusan pengelasan SMAW. Ketebalan root face yang terlalu tipis dapat menyebabkan pengotoran dan porositas, sedangkan ketebalan yang terlalu tebal dapat menyebabkan retak atau reject pada sambungan las. Selain itu, polaritas juga mempengaruhi terbentuknya defect. Penggunaan polaritas yang tepat dapat mengurangi terjadinya porositas dan retak pada sambungan las. Dapat disimpulkan bahwa dimana polaritas DCEN  menghasilkan tembusan yang ideal pada root face 2 mm, sedangkan Polaritas DCEP  menghasilkan tembusan yang ideal pada root face 3 mm, maka dari itu kami rekomendasikan polaritas DCEN sangat cocok untuk  pengerjaan root face 2 mm pada proses pengelasan SMAW.

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.

Abstract

Low student learning outcomes in certain competency elements of vocational education raise concerns about the adequacy of supporting factors, particularly facilities and infrastructure. This study aims to examine the influence of workshop facilities and infrastructure in the TKRO practicum on student learning outcomes at SMK Negeri 5 Kota Serang. Using a quantitative approach with a descriptive method, data were collected from classes XI TKR 1 and XI TKR 2, totaling 73 students selected through simple random sampling. The research data passed statistical assumption tests and were further analyzed using simple linear regression, yielding an R Square value of 0.119. This indicates that workshop facilities and infrastructure contribute 11.9% to the variation in student learning outcomes. It can be concluded that although the influence is not dominant, facilities and infrastructure still significantly affect student achievement. The findings of this study are expected to serve as a reference for schools and policymakers in evaluating and improving vocational workshop facilities to enhance educational quality. Furthermore, this research highlights the importance of integrating physical resources with pedagogical practices to maximize their impact. One of the study's novel contributions is the identification of a gap between perceived adequacy of facilities and actual student performance, which emphasizes the need for better alignment between infrastructure use and instructional design. Therefore, improving learning outcomes in vocational education requires not only complete facilities but also competent teaching, motivated learners, and a structured learning environment.
