Abstract

The green planthopper (Nephotettix virescens) is a major pest that significantly disrupts rice production by transmitting grassy stunt and empty grain viruses. This research aims to develop an effective botanical pesticide from Kuit lime (Citrus amblycarpa) and Gelinggang (Cassia alata) leaf extracts to control green planthopper populations. The study employed an experimental method with three treatment groups: Kuit lime leaf extract, Gelinggang leaf extract, and a combination of both, alongside a chemical pesticide as the control. Mortality rates of green planthoppers were recorded and analyzed. The results showed that the combined extract had the highest efficacy with a mortality rate of 97.5%, followed by Gelinggang extract (85%), and Kuit lime extract (82.5%). The chemical pesticide achieved 100% mortality. The study concludes that the combined extract of Kuit lime and Gelinggang leaves is a highly effective botanical pesticide against N. virescens. This finding supports the use of environmentally friendly plant-based insecticides as a sustainable alternative to synthetic pesticides. Further research is recommended to explore field-scale application and long-term effects on non-target organisms.

Abstract

The low level of science literacy among Indonesian students, as reflected in PISA scores below the OECD average, indicates a gap between educational goals and biology teaching practices that still focus on memorization and textbooks. The integration of the STEM (Science, Technology, Engineering, and Mathematics) approach offers a solution by linking scientific concepts to real-life contexts. This study used a systematic literature review method of ten national articles published in the last six years obtained through Google Scholar. The results show an increasing trend in publications, particularly in 2021, indicating growing attention to this topic. The main findings show that project-based approaches (STEAM-PJBL), interactive digital media such as flipbooks, and STEM-based E-LKPD are effective in improving science literacy and encouraging more participatory and reflective learning. Overall, the integration of STEM in biology learning has a positive impact on strengthening contextual science literacy that is relevant to the demands of the 21st century and the Society 5.0 era.Abstrak. Rendahnya literasi sains siswa Indonesia, yang tercermin dari skor PISA di bawah rata-rata OECD, menunjukkan adanya kesenjangan antara tujuan pendidikan dan praktik pembelajaran biologi yang masih berfokus pada hafalan dan teks. Integrasi pendekatan STEM (Science, Technology, Engineering, and Mathematics) menawarkan solusi dengan mengaitkan konsep sains pada konteks kehidupan nyata. Penelitian ini menggunakan metode tinjauan literatur sistematis terhadap sepuluh artikel nasional terbitan enam tahun terakhir yang diperoleh melalui Google Scholar. Hasil menunjukkan tren peningkatan publikasi, khususnya pada 2021, menandakan meningkatnya perhatian terhadap topik ini. Temuan utama menunjukkan bahwa pendekatan berbasis proyek (STEAM-PJBL), media digital interaktif seperti flipbook, dan E-LKPD berbasis STEM efektif meningkatkan literasi sains serta mendorong pembelajaran yang lebih partisipatif dan reflektif. Secara keseluruhan, integrasi STEM dalam pembelajaran biologi berdampak positif dalam memperkuat literasi sains kontekstual yang relevan dengan tuntutan abad ke-21 dan era Society 5.0.
