The availability of food resources and optimal environmental conditions influence the richness of dragonfly species in a habitat. The aim of this research is to identify the types of dragonflies in the Suranadi Nature Tourism Park area, West Lombok. This research was carried out on May 5, 2024, and was carried out in the morning and afternoon (09.30–13.00 WITA). The methods and techniques used in the research are field observation techniques using the free roam method. Observing dragonflies using the free-roaming method starts from the path area in the middle and edge of the forest, the field in the middle of the forest, and the pond. The research results showed that there were 8 species, belonging to 2 suborders and 2 families, with a total of 68 individuals. The species obtained include <em>Neurothemis terminata, Orthretum sabina, Diplacodes trivialis, Copera marginipes, Zyxomma petiolatum, Agrionoptera insignis, Orthetrum testaceum, </em>and<em> Onychothemis culminicola</em>. The diversity index (H') of dragonflies in the Suranadi Nature Tourism Park area is 1.66, indicating that the diversity of dragonfly species in this area is included in the medium category. The dominance index (C) shows 0.23, which means that dominance in this area is low. The equality index (E) in this area is also relatively high, with a figure of 0.80.</p>2024-06-25T12:32:16+08:00##submission.copyrightStatement##https://ejournal.unwmataram.ac.id/index.php/bios/article/view/2443Meta-Analysis of the Validity of STEM-Based Worksheets to Improve Students' Critical Thinking Skills2025-03-01T14:44:57+08:00Aswinda Wardaniswindawardani@gmail.comZulyusri Zulyusriswindawardani@gmail.com<p>One of the important skills that students need to have in the 21st century is critical thinking skills. Critical thinking skills can help students solve a problem. This study was conducted to determine the level of validity of STEM-based LKPD in improving students' critical thinking skills. This study was conducted using the meta-analysis method. Data collection was carried out by tracing journals related to STEM-based LKPD. The sample used was 10 journals related to the development of STEM-based LKPD. The results of the meta-analysis study for STEM-based LKPD were 85.34% with a very valid category, and the application of STEM-based LKPD affected students' critical thinking skills.</p>2024-05-31T00:00:00+08:00##submission.copyrightStatement##
