Abstract

This study presents an innovative design of a reactor vessel for Microwave-Assisted Hydro Distillation (MAHD), optimized for household-scale essential oil production. MAHD, as an energy-efficient alternative to conventional distillation methods, was applied through a newly designed reactor that emphasizes heat transfer optimization and energy efficiency. The reactor was constructed from stainless steel 304 with a capacity of 30–50 liters, integrated with a microwave heating system (500–2000 W), and equipped with a copper pipe condenser. Experimental results demonstrated an increase in essential oil yield of up to 30% compared to conventional hydrodistillation, with extraction times significantly reduced (reaching 100 °C in less than 15 minutes at 1000 W). Further analysis identified optimal operating conditions at 450 W with a feed-to-solvent (F/S) ratio of 0.35 g/mL. This design provides a significant solution for enhancing the efficiency of essential oil production in household industries, with potential implications for reducing energy consumption and improving product quality.

Abstract

Daun sirsak (Annona muricata L.) diketahui mengandung senyawa fitokimia, terutama flavonoid, yang berpotensi sebagai antioksidan dan anti kanker. Senyawa flavonoid dapat diperoleh melalui proses pemisahan seperti ekstraksi dengan memanfaatkan gelombang mikro yang mampu mempercepat proses ekstraksi. Penelitian ini bertujuan menentukan kondisi optimum ekstraksi flavonoid dari daun sirsak menggunakan metode microwave-assisted extraction (MAE). Proses ekstraksi dilakukan pada daya 264 W dan 440 W dengan variasi waktu 30, 45, 60, 75, dan 90 menit. Hasil ekstraksi dianalisis berdasarkan rendemen, kadar flavonoid total, dan identifikasi gugus fungsi melalui FTIR. Kondisi optimum nilai rendemen diperoleh pada daya 440 W selama 30 menit dengan rendemen 20,35 %, sedangkan kadar flavonoid tertinggi mencapai 303,642 ppm pada daya 440 W selama 90 menit. Analisis FTIR menunjukkan adanya pita serapan pada 300–3200 cm⁻¹ yang mengindikasikan gugus hidroksil (–OH) khas senyawa flavonoid.

Abstract

Teaching writing requires teachers to use an appropriate approach. Differentiated instruction can be applied as it can facilitate children's diverse learning needs as well as one of the embodiments of the emancipated curriculum. This mixed-method research explored the implementation of differentiated instruction in teaching English as a foreign language and focuses on writing narrative text to high school students. The main objective of this study is to explain the teacher’s preparation, implementation, and its effects. A teacher and a class of students participated in this study. The result shows that the teacher has an understanding and concept of the application of DI in the classroom. The teacher implemented content, process, and product differentiation based on the students’ readiness level and interest. DI was proven to have positive impacts on students. The research implications are expected to guide practitioners, policymakers, and other stakeholders in applying research findings in practical settings.

Abstract

Learning in the Economic Botany and Horticulture course is still dominated by lectures, resulting in limited student procedural skills and the absence of structured teaching materials. This study aims to develop and evaluate an eco-enzyme e-module to improve conceptual understanding, practical competence, and learning effectiveness. Using a Research and Development (R&D) approach with the ADDIE model, the study involved expert validation, a limited trial with one class, and pre-test/post-test assessment. Data was analyzed through descriptive validation scores, practicality ratings, and N-gain effectiveness. Results show that expert validation yielded very feasible scores for content (90%), media (88%), and instructional design (86%). The practicality test produced a very practical overall score of 87%, indicating high usability, readability, visual appeal, accessibility, and engagement. Implementation of the e-module increased students’ mean score from 62.4 (pre-test) to 91.2 (post-test), generating an N-gain of 0.77 categorized as high effectiveness. The e-module successfully integrates conceptual explanations, fermentation procedures, multimedia features, and project-based activities related to eco-enzyme production. In conclusion, the eco-enzyme e-module is valid, practical, and effective for supporting independent learning and enhancing students’ conceptual and procedural skills in accordance with the course learning outcomes.
