Abstract

Mechanical Design in general has the meaning of mechanical design using design software, the ability of Mechanial Design students is very limited, this is due to the resources of tools and people, FGD and workshop activities will help students improve their software design skills so that this will have a positive impact on the interest of vocational students in the field of Mechanical Design, the method used in this activity is the workshop method, FGD and questionnaire, after this activity is carried out, the results of student interest are quite high in the field of Mechanical Design, This is indicated by the results of activities in the form of questionnaires to 36 participants, obtained results as many as 100% of 36 students who stated the importance of Mechanical Design, before the community service activities were carried out there were students who assessed themselves with the highest ability of 9 students (25%) determining their ability assessment at 7, while after the workshop and FGD activities this resulted in an increase in student ability, namely the highest of 16 students (44%) determining their ability assessment at 8.

Abstract

Pengelasan merupakan proses penting dalam industri teknik, namun cacat pada sambungan las dapat menimbulkan risiko kegagalan struktural. Oleh karena itu, metode Non-Destructive Testing (NDT) menjadi pilihan utama untuk mengevaluasi kualitas pengelasan tanpa merusak material. Artikel ini bertujuan untuk meninjau berbagai teknik NDT, seperti Ultrasonic Testing (UT), Magnetic Particle Testing (MT), Penetrant Testing (PT), dan metalografi, dalam mendeteksi berbagai jenis cacat las. Metode penelitian yang digunakan adalah kualitatif deskriptif dengan pendekatan studi pustaka, mengacu pada jurnal terakreditasi nasional dan internasional. Hasil studi menunjukkan bahwa setiap metode memiliki keunggulan spesifik: UT efektif mendeteksi cacat dalam, MT unggul untuk logam feromagnetik, dan PT praktis untuk cacat permukaan. Penelitian ini juga menggarisbawahi pentingnya pemilihan metode berdasarkan jenis material dan kondisi industri. Temuan penting lainnya menunjukkan bahwa kombinasi beberapa metode NDT dapat meningkatkan akurasi deteksi dan keandalan inspeksi. Kesimpulan dari kajian ini adalah bahwa penerapan metode NDT yang tepat secara signifikan meningkatkan keselamatan kerja, efisiensi produksi, serta mutu sambungan las di berbagai sektor industri.

Abstract

Crusher and extruder machines for HDPE plastic materials are used as high density polyethylene (HDPE) plastic waste processing machines to produce plastic pellets. In designing the shaft, it is an important element in the construction of the crusher machine to transmit motor power through the pulley. Based on the design calculation results, the shaft diameter is 30 mm with a length of 392 mm and the shaft torsional moment is 6678.85 Kg.mm. The design results, stress and safety factor in the Finite Element Method (FEM) Solidworks simulation. The research purposes is to avoid shaft design failure. The shaft with AISI 1045 material is the most suitable for the required requirements with a safety factor value of 1.6675 with a maximum known stress value of 315,939,328 N/m2
