With the rapid development of e-learning in higher education, this study explores the application of the problem-based learning (PBL) learning model in the e-learning ecosystem. This article explores the concept of participatory engagement in the e-learning ecosystem and integrates it with PBL theory through the use of ICT to support interaction and collaboration. The research method used is R&D learning models in the Heavy Equipment Technology course at Universitas Negeri Padang. The research findings should be interpreted cautiously due to limitations such as differences in contexts across various courses and factors related to technology implementation in the learning environment. The study results show that it can improve learning outcomes and students’ critical thinking skills. Specifically, 70% have implemented Bloom’s cognitive taxonomy Level C4 and above, aided by a self-reflection participation process that enables students to reflect on content, learning processes, and understanding through internal dialogue, generating new ideas and solutions. This is evidenced by the results of the Path Coefficients test with P-Value EE → LO 0.050 and PBL → LO 0.046, as well as Specific Indirect Effect EE → SPR → LO 0.003 and PBL → SPE → LO 0.047 where the value is ≤ 0.05. The implications include guidance for designing effective e-learning ecosystems and adaptive learning strategies in higher education. Future research is recommended to further explore the impact of this integration and develop more effective PBL models in diverse courses and other educational institutions.

This study aims to overcome the impact of increased air pollution due to an increase in the number of motor vehicles, especially due to dependence on fuel oil. The focus of research is the use of banana peels as activated carbon to reduce vehicle exhaust emissions in the hope of providing environmentally friendly alternative solutions to reduce air pollution, utilizing the adsorption properties of banana peels, and using biogasoline to overcome potential fuel crises. The experimental method was used to test the effect of an activated carbon catalytic converter made from banana peel with biogasoline fuel on motorcycle exhaust emissions. The test results showed that the use of catalytic converters with biogasoline fuel tended to reduce carbon monoxide (CO) levels by an average of 18%, compared to standard conditions with pertalite fuel. The results of the Paired Samples T-Test showed a strong correlation with a value of 0.967 and a significance level of 0.033, where a small value of 0.05 means statistically significant.
