Abstract

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%.

Abstract

Renewable energy is energy that comes from renewable energy sources. Renewable energy sources are energy sources that can be used indefinitely and will never run out because they can be recovered in a relatively short time, including geothermal, wind, bioenergy, sunlight, water flows and waterfalls, as well as movements and temperature differences in ocean layers.” Solar panels are the main equipment in a solar power generation system which functions to convert sunlight energy into electrical energy directly. Nowadays, human dependence on energy concerns almost all aspects of life. Energy reserves originating from fossil fuels throughout the world are estimated to only be up to 40 years for petroleum, 60 years for natural gas, and 200 years for coal. The condition of limited energy sources in the midst of increasing world energy needs from year to year (energy consumption growth in 2004 alone was 4.3 percent), as well as to protect the earth from global warming and environmental pollution makes the demand for immediate realization of new technology for renewable energy sources. Therefore, the Community Service Team of the Department of Mechanical Engineering, Faculty of Engineering, Hasanuddin University held community service at the LE CENDEKIA Nature School on December 14 2023. The aim of this service is to increase understanding regarding renewable energy and carry out simple applications of renewable energy for students. The method of implementing the service is by interview on the importance of renewable energy and training in solar power assembly. There were 25 socialization and training participants. Community service results show an increase in understanding of the importance of renewable energy from 20% to 50%, and knowledge about solar power assembly from 5% to 45%.
