Abstract

In everyday life the use of plastic materials is very dominant. The use of this plastic material from year to year has greatly increased, which has resulted in an increase in plastic waste. Various parties have conducted research to reduce plastic waste into something that can have added value, including converting plastic waste into alternative energy sources in the form of fuel. Handling of plastic waste can be done by recycling it by heating it in a reactor so that it becomes liquid oil, then the oil is purified using a distillation apparatus. This study aims to determine the performance of oil refining distillation equipment from the processing of Low Density Polyethylene (LDPE) plastic waste which can be used as fuel. The research method used is the performance test for refining oil from the processing of plastic waste which is heated with a distillation apparatus. Testing the plastic oil purification distillation apparatus was carried out 5 times, the test was carried out by means of each oil being put into the reactor totaling 3,500ml each time of testing, from the observations it showed that the results of tests 1 to 5 produced refined oil 1 = 1,592ml, 2 = 1.627ml, 3 = 1.609ml, 4 = 1.616ml, 5 = 1.319ml. The total amount of refined oil is: 7,768ml and the average temperature of the reactor is 184.6oC.

Abstract

This community-based empowerment activity program involves SUWALA concrete brick business group partners in Liwutung Dua Village, Pasan Sub-district, Southeast Minahasa Regency with the main problem being the lack of quality of concrete brick products. To overcome this problem, empowerment activities and the application of concrete brick mix technology using local natural resources and industrial waste, namely metakaolin and fly ash, were carried out. The goal is to apply the research results to the community through the manufacture of concrete bricks based on local materials in order to improve the competitiveness and welfare of business groups and the community in general. The method used in this activity is in the form of a workshop on the technology of making concrete brick mixture and education involving business groups, village officials and students. Through this service activity, a mixture technology that produces quality concrete brick products and meets the Indonesian National Standard is obtained. However, it is still necessary to control the quality of sand used, the ratio of cement:sand mixture and the method of implementing the mixture by the trained workers. Through business management education, group members' skills in preparing financial reports increased by 80% but further guidance is still needed regarding marketing management, especially with digital technology. Expectations: It is expected that this activity can improve and increase the income of business groups and encourage improvements in the economic and social values of the community. Concrete brick products from fly ash waste and metakaolin can be a village flagship product that improves community welfare and business opportunities in Southeast Minahasa Regency.
