Abstract

This research aimed to determine the extent to which the learning outcomes of class VIII G students of SMP Negeri 14 Denpasar had improved through the Jigsaw Type Cooperative learning method in learning mathematics regarding the Pythagorean Theorem. This research was classroom action research with the research subject being class VIII G of SMP Negeri 14 Denpasar Semester 1 in the academic year 2023/2024. Data on student learning outcomes was collected using written tests in the form of multiple choices. The result of this research showed that the first increase occurred in cycle I, 22 of the 42 students who took the test completed the test with a percentage of 52.4%. In cycle II, there was an increase in students who completed the test by 34 students out of 42 students who took the test with a percentage of 81%. It could be concluded that there was an increase in student learning outcomes in learning mathematics regarding the Pythagorean Theorem by applying the Jigsaw Type Cooperative learning method.

Abstract

This community service program aims to empower the coastal community of Huangobotu Village through an innovative approach to utilizing organic waste from the Inengo Fish Auction House (TPI) by converting it into nutrient-rich dry fertilizer. Organic waste generated from auction activities—such as fish residues, entrails, bones, skin, and scales—has not been optimally utilized. This condition has led to various environmental problems, including unpleasant odors, water pollution, and declining sanitation around the TPI area. Limited knowledge and inadequate waste-processing technology have further exacerbated the situation. Therefore, community empowerment initiatives are needed to transform this waste into more valuable products. Through a participatory approach, the implementing team engaged coastal residents, particularly youth groups (karang taruna), in technical training and mentoring for the production of dry fertilizer. The activities included raising awareness of proper waste management, demonstrating processing techniques, and applying simple methods using microbial activators. The results showed an increase in participants’ knowledge and skills in converting organic waste into useful, marketable fertilizer. Participants were able to independently apply basic processing techniques using microbial activators. Management and production levels improved by 70% and 75%, respectively, indicating the program’s effectiveness in enhancing awareness of proper waste handling. Beyond addressing environmental issues, the program also fostered greater understanding of circular economy practices within the community. Furthermore, the dry fertilizer innovation has encouraged the emergence of local business opportunities based on fishery waste. This waste-management model is expected to contribute to reducing coastal pollution and supporting environmentally friendly agricultural development in Gorontalo. The program effectively strengthened the community’s capacity in processing organic waste, and the dry fertilizer innovation has strong potential as a sustainable waste-management solution.
