Proses pengelasan gesek dilakukan dengan memvariasikan putaran (550 rpm, 1020 rpm dan 1800 rpm) serta media pendinginan air dan oli. Hasil pengelasan gesek tersebut kemudian dilakukan pengujian untuk mengetahui kekuatan sambungannya. Perolehan data awal penelitian melalui proses pengujian impak dan pengujian puntir yang dilakukan pada mesin uji impak dan mesin uji puntir. Hasil penelitian menunjukkan bahwa nilai kekuatan impack dan puntir tertinggi terjadi pada putaran 1800 rpm dengan nilai masing-masing sekitar 1.23 J/mm2 dan 443.50 N/mm2. Media pendinginan yang diberikan (Air dan Oli) juga berpengaruh terhadap kekuatan sambungan hasil lasan. Hal ini ditandai dengan terjadinya perbedaan kekuatan impack dan puntir, kekuatan impack tertinggi pada pendinginan air 1.16 J/mm2 dan pendinginan oli 1.23 J/mm2, serta kekuatan puntir tertinggi pendinginan oli 443.50 N/mm2 dan pendinginan air 419.91 N/mm2.

The objective of this study is to improve the quality and efficiency of the verification process which is crucial for processing green bean seeds by upgrading the green bean skin separating machine. This change entails improving engine rotation in addition to changing engine mechanics and parts. The engine was tested at 350 rpm, 425 rpm, and 500 rpm during the experimental phase. According to the data, 350 rpm is the ideal engine speed for separating green bean seeds from the pod skin, with a differential capacity of 54 kg/hour. When ninety percent of the green bean seeds are undamaged and out of the pod skin, they are combined with other components. This machine may serve as a commercial solution to improve the quality and efficiency of processing green bean seeds. These encouraging outcomes highlight how important technology is to the agro-industrial and agricultural sectors. By processing green bean seeds more effectively and of higher quality, technology may also assist the environment and the economy.

The process of recycling plastic waste is one way of processing plastic waste. Plastic waste in the form of plastic bottles and cups has a high selling value when it is recycled. The Paraikatte Rong waste bank in Makassar City has been in the plastic waste processing business for 5 years. This waste bank only collects and sorts plastic waste due to the unavailability of plastic chopping machines that can help the plastic waste recycling process. Therefore, the Community Service Team of the Department of Mechanical Engineering, Faculty of Engineering, Hasanuddin University, with the implementation of appropriate technology designed and built a plastic chopping machine for the Paraikatte Rong waste bank. The method used is to conduct training on the use and maintenance of a plastic chopping machine. The purpose of this service is for the waste bank to carry out the recycling process optimally and efficiently so as to increase the economic value of plastic waste. The scissor system for chopping plastic is applied to the chopping machine so that the chopping results are smoother. The chopping machine consists of 3 dynamic blades and 2 static blades which can be adjusted to the density of the blades. This machine has a capacity of 100 kg/hour using a 7.5 hp petrol engine. The success of this community service activity can be seen from the increase in public understanding based on survey results where the total level of understanding/very understanding of the benefits of selecting plastic waste has increased from 35% to 52.6%. The operation of the plastic chopping machine has increased from 55% to 80%. The maintenance of the plastic chopping machine has increased from 53% to 87%.

This research explores the evolution of technology in pineapple peeling, from the use of manual knives to sophisticated pneumatic technology. The main focus is on pineapple peeling machine design, working principles, and calculating time efficiency between machine and manual peeling. The aim is to broaden students' understanding of designing machines and provide guidance for students in applying pneumatic technology. The study began with literature observations and field studies to collect price and specification data as well as information components about pineapple. Next, planning, manufacturing, and testing of the machine are carried out. Data was collected from both stripping processes for further analysis. The research results include machine designs with main components such as actuators, knife blades, knife fasteners, and machine frames, as well as pneumatic component specifications, which are explained in detail. A comparison of stripping times shows a significant increase in efficiency with the machine, with the fastest time of 9.09 seconds and the longest time of 447 seconds for manual stripping. This research contributes to the development of pineapple processing technology and increases efficiency in the fruit processing industry as a whole.

This study focuses on the design and performance evaluation of a shallot peeling machine aimed at enhancing processing efficiency for culinary applications. The machine is equipped with a ¼ hp electric motor operating at 1400 rpm, along with a specially designed peeling disc that utilizes rubber friction around the drum to effectively peel the shallots. The machine’s large-capacity container is designed to prevent the test materials from being ejected during operation, ensuring stability throughout the peeling process. Testing was conducted in two stages: the first stage used 1 kg of shallots, and the second stage used 2 kg, both at a motor speed of 1400 rpm. In the first test stage, the machine achieved an average peeling efficiency of 82% after one minute (equivalent to 820 grams of peeled shallots from 1 kg), which increased to 94.2% (942 grams) after two minutes and reached 98.5% (985 grams) after three minutes. In the second test stage with 2 kg of shallots, the machine recorded an average peeling efficiency of 96.4% (1929 grams). The machine demonstrates a production capacity of 30 kg per hour, far exceeding the previous model's capacity of only 14 kg per hour. These findings confirm that the newly designed shallot peeling machine meets performance expectations and offers a substantial improvement in peeling efficiency and productivity.
