Abstract

Chemistry learning, especially in Indonesia, has not been able to direct students to master critical thinking skills. Using appropriate media and learning models can improve students' critical thinking skills. One of the efforts to improve critical thinking skills is using Chemsketch media with STEAM-based learning models (Science, Technology, Engineering, Art, Mathematics). This study aims to analyze the effect of using ChemSketch in STEAM-based learning (Science, Technology, Engineering, Art, Mathematics) on improving students' critical thinking skills on chemical bonding material. This study used a Non-equivalent control group design. The population in this study were all grade X students of SMA Negeri 1 Karangwareng in the 2023/2024 school year, with the samples used including one class X-7 as the experimental class and one class X-6 as the control class. The data obtained were then analyzed using the N-Gain and simple linear regression tests. The results showed that: 1) STEAM-based learning significantly increases critical thinking skills with an N-Gain value of 0.66. 2) STEAM-based learning significantly affects critical thinking skills with a value of 0.002. It can be concluded from the results of this study that students in the experimental group experienced a significant increase in critical thinking skills compared to the control group. This indicates that integrating ChemSketch in STEAM-based learning can be an effective strategy to improve students' ability to analyze, evaluate, and solve problems related to chemical bonding.

Abstract

Bawang merah merupakan salah satu penghasil terbesar di daerah Jawa Barat, Tepatnya di Kabupaten Majalengka dengan produksi sebesar 7,38% setiap tahunnya. Produksi bawang merah bersifat musiman dan dipengaruhi oleh curah hujan yang tinggi sehingga petani tidak menanamnya di musim hujan karena akan berdampak pada kerusakan fisik daun bawang merah dan pembusukan umbi sehingga mengakibatkan terjadinya penumpukan limbah bawang merah. Tujuan pengabdian ini yaitu untuk memanfaatkan limbah kulit bawang merah untuk dijadikan sebagai minuman herbal pencegah timbulnya bakteri staphyoloccus aureus pada kulit wajah manusia serta mengetahui kelayakan produk untuk dipasarkan ke masyarakat guna meningkatkan pendapatan ekonomi penduduk sekitar. Metode yang digunakan yaitu pelatihan pembuatan sirup kepada masyarakat Desa Sukasari Kaler. Hasil pengabdian ini adalah produk sirup kulit bawang merah dan 90% responden setuju produk minuman sirup kulit bawang merah ini dipasarkan ke masyarakat. Disimpulkan melalui Uji Organoleptik sirup dari limbah kulit bawang merah sebagai minuman pencegah timbulnya bakteri staphyoloccus aureus pada kulit wajah manusia.
