Abstract

Research on the development of learning media for Android-Based Interactive E- modules on colloidal material aims to produce valid, practical and effective learning media. The floating model used is a 4D development model. The trial of the learning media developed was carried out on students of SMAN 1 Kotabaru for the 2020/2021 academic year. The trials carried out were individual trials, small group trials and limited trials. Data collection techniques used validation sheets, readability questionnaires, response questionnaires and test assessments. Data analysis used descriptive analysis. The results showed that the developed media had met the following criteria: (1) Valid, based on a feasibility test by a group of experts with an average of 91.66% (very valid); (2) Practical, based on individual, group readability tests, as well as student and teacher response questionnaires with successive scores of 3.30 (very good); 3.40 (very good); 3.34 (very good) and 3.70 (very good); (3) Effective, based on the results of a limited trial, it can be seen from the average n-gain score of 0.73 (high). Overall, the e-module developed is able to improve students' conceptual understanding skills and as a form of renewal in chemistry learning

Abstract

The underutilization of pineapple peel waste and fluctuations in pineapple prices are among the challenges faced by Tinggiran Darat Village. The objective of this Community Empowerment Partnership (PKM) initiative is to empower pineapple farmers by transforming pineapple peel waste into economically valuable products, namely eco-enzymes and liquid laundry detergent. To address these issues, the program adopts an Asset-Based Community Development (ABCD) approach, involving 40 members of the PKK/ Pemberdayaan Kesejahteraan Keluarga (Family Welfare Movement) and youth organizations. The evaluation results through pretest and posttest showed a significant increase in all indicators of participant understanding, namely from 52.25 to 87.5 on the eco-enzyme concept, from 50.0 to 86.75 on the production process, from 48.0 to 89.0 on environmentally friendly detergent products, and from 60.0 to 87.5 on digital marketing and branding aspects, all of which were in the very good category. In addition, the results of the public perception analysis showed a positive level of acceptance of eco-enzyme-based detergent products, with 84.4% of respondents rating the product's cleaning power as good, 90.6% stating it was safe for the skin, 78.1% rating the packaging as quite attractive, and 81.3% stating a willingness to reuse and recommend the product. As an explicit impact, the community is now able to independently process previously discarded pineapple peels into marketable natural detergent products. This has proven effective in reducing the village's organic waste volume while simultaneously creating new, sustainable economic income opportunities for the local community.
