Abstract

Eco-enzymes are liquid products resulting from the fermentation of organic wastes such as fruit and vegetable wastes, sugar, and water. The aim of this study is to investigate the potential of eco-enzymes as liquid organic fertilizers using organic waste from orange and pineapple peels. In the experimental design, he used a completely randomized design with three replicates of three organic waste compositions. The treatments used are pineapple peel, orange peel, and a mixture of pineapple and orange peel. Ecoenzyme is prepared by mixing organic waste with water and molasses in a ratio of 10: 3: 1 and fermenting it for 30, 60 and 90 days. The results showed that the composition of pineapple and orange peel produced an eco-enzyme solution with the highest nitrogen content, highest amylase enzyme activity, and highest acidic pH. The color of eco-enzyme varies from light brown to dark brown, and the resulting sour aroma indicates that the fermentation process is progressing smoothly.

Abstract

This research analyzes teacher performance in developing Integrated Social Sciences teaching materials at SMPN 7 Medan. The research method used is a qualitative descriptive method. The interview results show that teachers are able to organize teaching material by combining various fields of study, such as Geography, Economics, History and Sociology, by agreeing on a theme first before presenting it to students. The development of Geography teaching materials, which is considered more difficult than other fields of study, is carried out with a longer time allocation and the use of local resources. In teaching methods, teachers apply fun approaches such as discussion, Contextual Teaching Learning (CTL), Quantum Teaching, and inquiry to increase student involvement and encourage critical thinking. However, obstacles in developing teaching materials, especially Geography material, are overcome by enriching literacy and utilizing learning methods based on group discussions and case studies. Integrated social studies learning at SMPN 7 Medan becomes more effective and relevant to students' daily lives thanks to the contextual approach applied by the teacher.

Abstract

Clean water is a basic necessity that not only affects health but also social welfare and environmental sustainability. The aim of this research is to evaluate the level of public awareness in the Tegal Sari Mandala II sub-district regarding the use of clean water for household purposes and to identify the factors that influence public awareness in the utilization of clean water in the Tegal Sari Mandala II village. This research uses a qualitative approach with a descriptive evaluative method. Data in this study were collected through interview techniques, observation, and document studies, and analyzed using thematic analysis techniques. The results of this study indicate that community awareness in the Tegal Sari Mandala II sub-district is quite good, but the availability of clean water in this area is still limited due to the scheduling of PAM water distribution, which is from 8:00 AM to 4:00 PM, making it difficult for residents to meet their clean water needs for household use.
