Abstract

Background: Bawang merah merupakan salah satu jenis sayuran yang manfaatnya banyak digunakan oleh masyarakat Indonesia. Bawang merah mempunyai kandungan sulfur compound seperti Allyl Propyl Disulphida (APDS) dan flavonoid seperti quercetin yang dipercaya bisa mengurangi resiko kanker, penyakit jantung dan kencing manis. Kulit bagian luar bawang yang mengering dan kerap berwarna kecoklatan kaya serat dan flavonoid serta antibakteria terhadap Stapylococcus aureus dan E.coli. Bawang merah memiliki senyawa aktif sehingga dapat dimanfaatkan sebagai teh herbal dan salah satu metode penanganan terhadap limbah organik dikarenakan limbahnya menimbulkan pencemaran lingkungan berupa aroma yang tidak sedap. Tujuan dari pengabdian untuk mengetahui pengolahan limbah kulit bawang merah menjadi teh herbal serta identifikasi tingkat kesukaan masyarakat terhadap teh herbal dari limbah kulit bawang merah sebagai minuman jamu tradisional. Metode: Diujicobakan kepada 20 orang responden yang berasal dari sekelompok ibu-ibu PKK Desa Cibunut Kecamatan Argapura Kabupaten Majalengka, dengan menggunakan pemilihan sederhana terhadap limbah kulit bawang yang masih dapat digunakan sebagai raw material untuk pembuatan teh herbal. Hasil: Hasil metode survei kelayakan menunjukkan hasil yang baik bahwa teh herbal ini disukai dan untuk diterima dilingkungan masyarakat. Keberlanjutan program ini yaitu produk ini akan tetap melanjutkan produksi di setiap tahunnya yang dipegang oleh kelompok ibu-ibu PKK Desa Cibunut. Kesimpulan: Limbah kulit bawang merah dapat dimanfaatkan sebagai minuman jamu tradisional.

Abstract

This study addresses the low level of students’ critical thinking skills in chemistry learning, particularly in the context of thermochemistry, which is an abstract and complex concept to visualize. To overcome this challenge, Project-Based Learning (PBL) was integrated with the STEM (Science, Technology, Engineering, and Mathematics) approach. The research aimed to examine the improvement of students’ critical thinking skills and to explore their responses toward the PjBL-STEM model. A quantitative experimental method was employed with purposive sampling of 11th-grade senior high school students. Research instruments included a critical thinking test based on Facione’s indicators, observation sheets, and student response questionnaires. The data were analyzed using both descriptive and inferential statistical techniques. The findings revealed a significant improvement, with the average score increasing from 47% in the pre-test to 74% in the post-test. Students showed better performance in interpretation, analysis, evaluation, inference, explanation, and self-regulation. Furthermore, responses toward the PjBL-STEM model were highly positive, with 67% of students agreeing and 21% strongly agreeing with its implementation. These results suggest that PjBL-STEM provides a practical, interactive, and contextual learning experience, thereby enhancing students’ critical thinking skills in chemistry education.

Abstract

One of the ways to reduce greenhouse gases can be done through waste management from the source, because organic waste is one of the sources of methane gas that causes the greenhouse effect. The lack of education at the community level about efforts to reduce waste thrown away by processing waste is one of the causes of waste accumulation in landfills. This research aims to train the community to make an independent Vertical Composter Garden (VCG) in order to reduce organic waste in their area. The training was held in Cengkuang Village, Palimanan District, with a total of 16 participants. The method used is periodic training and mentoring followed by a final evaluation. The result obtained was that the level of understanding of participants increased after being given an explanation of waste management materials and how to make VCGs. The planting period depends on the type of plant. The fastest harvest period is only 14 days for chives, while the longest is for chili plants, which takes about 3.5 months from seeding to harvest.
