Abstract

The milling process is one of the essential techniques in the manufacturing industry used to produce components using milling machines. For engineering or manufacturing science students, understanding the milling process is relevant and valuable. The milling process is commonly used in various industrial sectors, including automotive, aircraft, energy, etc. Understanding the basic principles and techniques of the milling process will provide a solid foundation for students to develop careers in these various industries. The milling process involves the use of a milling machine. Students skilled in operating these machines will have a competitive advantage in the world of work. They will be able to contribute to product development, tool design, and efficient manufacturing processes. Students will learn how to read and understand technical drawings, choose the right cutting tools, as well as workpiece measurement techniques prior to the milling process. This capability will broaden their understanding of product engineering and design. The results of the training showed that almost all students were able to perform basic techniques in the milling process, as evidenced by their ability to produce products according to the technical drawings provided.

Abstract

Tingginya limbah sampah plastik merupakan permasalahan global yang berdampak negatip terhadap lingkungan sehingga perlu cara penanggulangan yang effective dan effisien. Kegiatan PKM bertujuan mengembangkan dan mengoptimalkan pengolahan limbah plastik menjadi produk yang bernilai ekonomis tinggi serta mengurangi dampak negatip limbah plastik ke lingkungan. PKM dilaksanakan di mitra pegepul limbah plastik yang berlokasi di daerah Medan Johor. Metode PKM meliputi: sosialisasi program PKM, implementasi mesin pencacah plastik tipe crusher berkapasitas 250 kg/jam, pelatihan pengoperasian/perawatan mesin pencacah palstik dan manajemen keuangan, serta evaluasi dan monitoring. Hasil kegiatan PKM berdampak dengan meningkatnya kapasitas produksi dan nilai jual sampah plastik. Dengan dilakukannya kegiatan ini akan menambah pengetahuan masyarakat dari pelatihan yang telah diberikan. Selain itu, dapat dipraktekkan oleh masyarakat sampah plastik di wilayah kota Medan.

Abstract

Fatigue cracks can occur because the material is unable to withstand the load applied repeatedly. A nonlinear vibroacoustic method was introduced to overcome this problem. This is because this method is one of the best solutions because it is suitable for detecting fatigue cracks which is sensitive enough to detect small cracks. The aim of the research is to determine the effect of laser distance measurements on fatigue crack detection using the vibroacoustic method. Therefore, there are steps or procedures that include test object preparation, tensile testing, dynamic tensile testing, and modal analysis. Three different vibration modes are selected to excite the low frequency modes. The vibroacoustic method is a method based on the propagation of high frequency sound waves in solid structures with low frequency excitation. The trained output signal will be converted from the time domain to the frequency domain supported by the use of MATLAB software. The analysis results show that there is a significant influence on the detection of fatigue cracks in aluminum using the vibration acoustic method. The analyzed data shows that measuring the laser distance will influence the crack detection process. Fatigue cracks can occur because the material is unable to withstand the load applied repeatedly.
