Abstract

The Science, Technology, Engineering, and Mathematics (STEM) approach to learning plays an important role in improving teacher competency, learning innovation, and technology use skills. However, the results of an initial survey at Sekolah Indonesia Makkah showed that 44.12% of teachers faced challenges in the form of a lack of training and understanding related to STEM integration. This study involved 34 teachers and aimed to improve their ability to implement STEM-based learning through the Collaborative Professional Development (CPD) approach. The results showed that teachers who participated in CPD activities experienced a significant increase in their understanding and readiness to implement STEM. In addition, teachers began to realize the benefits of STEM learning in developing students' affective, cognitive, and psychomotor aspects, as well as its potential as a means of career guidance. As many as 52.94% of teachers stated that they strongly believed that STEM was important to implement, and 58.82% considered the CPD program to be continued. This study recommends that CPD training be carried out continuously with more applicable and contextual materials. Strengthening collaboration between teachers and the integration of STEM-based curriculum is also needed to support the sustainability and effectiveness of the program in the long term.

Abstract

Nata is a fermented product made from cellulose and synthesized by Acetobacter xylinum, offering potential as a functional food rich in dietary fiber. This study aimed to evaluate the effect of varying volumes of molasses and mung bean sprout (Phaseolus radiatus L.) broth as sources of carbon and nitrogen on the crude fiber content of nata produced from watermelon (Citrullus lanatus) rind waste. Each fermentation medium had a total volume of 1000 mL and included the following treatments: N1 (5% molasses and 5% sprout broth), N2 (10% molasses and 10% sprout broth), N3 (15% molasses and 15% sprout broth), and N0 (control), which used coconut water, granulated sugar, and food grade urea. Fermentation was carried out under static conditions at room temperature for 10 days, and the resulting nata was analyzed for crude fiber content using the gravimetric method. The results showed that variations in the volumes of molasses and sprout broth significantly influenced the crude fiber content of nata (p < 0.05). The Duncan Multiple Range Test (DMRT) further confirmed statistically significant differences among treatments. Treatment N2 produced the highest crude fiber content (8.05 ± 0.02%), while the control (N0) yielded the lowest value (5.11 ± 0.01%). The absence of nata formation in N3 indicated substrate saturation and nutritional imbalance. These findings emphasize the importance of carbon and nitrogen balance in optimizing nata production from agroindustrial waste. Treatment N2 was identified as the most effective in enhancing both crude fiber content and overall nata quality.

Abstract

Perkembangan global menuntut peningkatan kompetensi abad ke-21 sebagai upaya dalam tujuan pembangunan keberlanjutan, salah satunya adalah keterampilan pemecahan masalah. Hasil studi PISA 2022 menunjukkan rendahnya kemampuan peserta didik Indonesia dalam sains dan pemecahan masalah. Penelitian ini bertujuan untuk merancang dan mengembangkan E-LKPD yang berbasis Science, Environment, Technology, and Society (SETS) pada materi perubahan lingkungan khususnya subtopik permasalahan lingkungan untuk melatihkan keterampilan pemecahan masalah peserta didik. Model pengembangan yang digunakan dalam penelitian ini yakni ADDIE yang mencakup tahap analisis, desain, pengembangan, implementasi, dan evaluasi. Validitas E-LKPD diperoleh melalui proses validasi oleh pakar, efektivitas diukur menggunakan analisis skor N-Gain dari hasil pre-test dan post-test, sedangkan tingkat kepraktisan dinilai melalui angket tanggapan peserta didik. Temuan penelitian mengungkapkan bahwa E-LKPD tergolong sangat valid dengan perolehan skor 96,24%, sangat efektif melatihkan keterampilan pemecahan masalah dengan N-Gain 0,79 kategori tinggi dan 100% peserta didik tuntas dengan rata-rata ketercapaian tiap indikator 88,98%, sangat praktis berdasarkan respon peserta didik 93,14%. Dengan demikian, E-LKPD berorientasi SETS yang dikembangkan dinyatakan layak dan dapat digunakan untuk meningkatkan kualitas pembelajaran biologi.
