Abstract

The transmission system is a system that functions to change the torque and speed (rotation) of the torsion engine and has a different speed to keep it moving, the transmission system usually uses gears and fulleys as a rotation successor. Safety shoes are very important protective equipment to prevent injury from falling objects. In addition, it is very important to keep safety shoes clean to avoid falling or slipping while working. In a previous study, namely the Design of a Safety Shoes Cleaner, it did not use a transmission system so that the rotation of the electric motor shaft which was transmitted to the cleaning brush experienced a very large resistance and frictional force. In this study, the transmission system used in the shoe cleaning machine is gear transmission and pulley transmission, the number of gears used is 2 which type of gear used is bevel gear while the number of pulleys used is 5. The purpose of this study was to modify the transmission system of the safety shoe cleaning machine so that it produces counterclockwise rotation on the brush shaft at the top of the machine. This research was carried out in the repair laboratory and workshop of the Morowali metal industry polytechnic from April to September 2022, the research method consisted of planning, designing and manufacturing processes, then testing was carried out so that it could be concluded that the transmission system was running well. By pairing two straight gears on the engine transmission system so as to produce opposite rotation on the upper brush shaft which is transmitted from the motor to the shaft through the gear transmission and fulley belt.

Abstract

Mekarti Jaya Village is located in the PT Industrial Area. IMIP, the need for industrial workers in the PT area IMIP continues to increase as the investment value in the area increases. To prepare the people and youth of Mekarti Jaya village to be able to take advantage of job opportunities in industries located in the PT area. IMIP needs to carry out training to increase competency, especially in the field of Shielded Metal Arc Welding (SMAW) welding position 2F. The selection of SMAW welding training materials was based on survey results, in which the need for welding specialist workers was the greatest need for industries in the PT area. IMIP. Training activities are carried out for approximately 1 month, starting with the preparation, implementation, and training results stages. The activities were carried out on February 27–29, 2022. Training activities were carried out at the Morowali Metal Industry Polytechnic Machinery Maintenance Engineering study workshop. The training was attended by ± 16 young people and residents of the village of Mekarti Jaya. The results of the training carried out were an increase in understanding and knowledge before and after the training activities were carried out; this was shown by the results of the constant shape of the ridges, welding position 2F, and the results of the post-test.

Abstract

Alignment is a technique used to maintain machine components that rotate or transfer power so they can operate as effectively as possible and prevent damage to other machine components from errors made during installation or maintenance. Alignment is a maintenance activity that is often carried out on machines in industry and machines within the Morowali Metal Industry Polytechnic, especially in the Mechanical Maintenance Engineering Study Program. Competency in the alignment of gears and bearings is very much needed for prospective mechanics in the industry. The purpose of making this tool is as a simulation tool for learning alignment to achieve straightness and centricity between two rotating shafts (drive and driven shaft) to prevent friction, vibration, and other problems that can reduce tool life and, of course, increase expenditure costs. for repair or replacement of heavy equipment. In the process of designing this alignment tool, a drive method is used in the form of a sprocket and chain, where the link between the drive motor and the shaft to be moved is the sprocket and chain method. This research serves to help produce a design by considering the user's perspective so that the design results can be useful effectively. From the test results, the gear alignment setting tool can function well with the help of an inverter so that motor rotation can be reduced and can be controlled according to the desired conditions. The previous alignment setting tool had an RPM: of 1450.8 and the alignment setting tool that was made had an RPM: of 1455.7 with a frequency of 50 Hz so it can be concluded that this tool can be used for practical work in machine repair and maintenance laboratories.

Abstract

Modifikasi geometri pelat absorber merupakan salah satu pendekatan strategis untuk meningkatkan perpindahan panas pada kolektor surya, namun kajian eksperimental yang membandingkan secara langsung pengaruh bentuk gelombang segi empat dan setengah lingkaran terhadap kinerja sistem pengering jagung masih sangat terbatas. Penelitian ini bertujuan menganalisis pengaruh geometri pelat absorber bergelombang segi empat dan setengah lingkaran terhadap kinerja termal kolektor dan performa pengeringan jagung menggunakan metode eksperimental langsung (direct experimental method) di bawah kondisi radiasi matahari alami. Pengujian dilakukan terhadap 6 kg jagung dengan kadar air awal 25,5% (basis basah) selama 360 menit, dengan interval pengamatan setiap 45 menit. Parameter yang dianalisis meliputi penurunan kadar air, kecepatan udara, laju aliran massa udara (ṁa), energi panas berguna (QU), dan efisiensi termal kolektor (ηth). Efisiensi termal tertinggi dicapai pada interval pengeringan menit ke-225, yaitu sebesar 39,8% untuk pelat segi empat dan 32% untuk pelat setengah lingkaran. Hasil menunjukkan bahwa pelat absorber segi empat memberikan kinerja lebih baik dibandingkan setengah lingkaran: kadar air akhir yang dicapai sebesar 9,2% berbanding 10,8%; kecepatan udara maksimum masing-masing 0,9 m/s dan 0,8 m/s. Peningkatan performa ini dipengaruhi oleh luas permukaan efektif yang lebih besar serta turbulensi aliran yang lebih tinggi pada geometri segi empat, sehingga optimasi geometri absorber terbukti meningkatkan efektivitas sistem pengering surya.
