Abstract

Fuzzy C-Means (FCM) adalah salah satu teknik clustering yang sering digunakan, tetapi memiliki kelemahan yaitu sensitif terhadap local optima dan sensitif terhadap pusat cluster awal. Forest Optimization Algortihm mampu mengatasi kelemahan dari FCM. FOFCM dibangun dengan 2 jenis jarak yaitu Euclidean dan Mahalanobis. FOFCM memiliki performa yang lebih baik dari FCM, karena sebagian besar iterasi FOFCM lebih sedikit dari FCM. FOFCM Mahalanobis menghasilkan nilai fungsi objektif paling kecil pada sebaran data hyperspherical dibandingkan dengan FOFCM Euclidean maupun FCM. Oleh karena itu, dapat disimpulkan bahwa FOFCM Mahalanobis cocok untuk data hyperspherical.

Abstract

Climate change is an ongoing critical issue that has impacted all countries globally, including Indonesia. The major problem in environmental learning is how affected society can adapt and mitigate climate change. The public can quickly obtain information regarding climate change, but educational information on methods to adapt and mitigate climate change still needs to be improved. Students are crucial in assisting the government in educating the public on methods of adapting to and mitigating climate change. In response to rapid technological advancements, Electronic Information of Adaptation and Mitigation (EI-AME) was developed as an interactive digital learning module to support environmental education. This study aims to examine the improvement of students’ communication skills in climate change education through the implementation of EI-AME. The experimental method was used in this research, with a sample of 146 students from two universities in Jakarta, Indonesia. This research's design is a pretest-posttest with a control class. The instrument used consisted of 14 essay questions with 4 different aspects of communication skills. The research outcome revealed that students' communication skills scores significantly increased in the experimental class compared to the control class. This shows that EI-AME can be an innovative teaching material in the future for strengthening students' communication skills. Further research should be conducted to highlight how such communication skills can help students transfer information in society.
