Abstract

Learning that focuses on achieving product mastery is not optimal in facilitating students to create quality research ideas. In this research, we implemented MPBR to analyze the quality of science research ideas from students. To collect research ideas from students, the documentation method is used. Documents as qualitative instruments obtained through this method are assessed based on four criteria. They are suitability to the scope of scientific studies, the presence of research problems, the accuracy of the editorial title formulated from the research problem, and the urgency of the study variables. The data obtained was analyzed quantitatively and qualitatively. The quantitative analysis that we carry out is proportion analysis. The qualitative analysis includes data reduction, visualization, and conclusion. We found that all research ideas are within the scope of scientific studies and are based on research problems. However, only some scientific research ideas have appropriate title formulations, and the variables need to be studied further through the research process. This has implications for the overall quality of research ideas. The quality of research ideas in the outstanding category is 44.06%. The proportion in the good category is 14.68%, and the remainder is in the fair category, with a ratio of 41.26%. The conclusion is that implementing the PBR model effectively trains students to create scientific research ideas based on problems they find in the surrounding environment.

Abstract

This study aims to ascertain how grade XI students at SMAN 8 Mataram's mind mapping assignment affects their capacity for original thought and their grasp of biological ideas. On samples chosen by random sampling, this study employed a pretest-posttest control group design and a quasi-experiment. While written assessments in multiple-choice questions were used to get information on topic mastery, mind-mapping assignments were used to gather information on students' creative thinking abilities. The findings demonstrated that mind-mapping exercises significantly impacted students' comprehension of biological topics and enhanced their capacity for creative thought, moving them from less creative to highly creative criteria. Pearson correlation test results showed a positive relationship between creative thinking skills and students' mastery of biological concepts in the medium correlation category. Mind mapping assignment has a positive influence in improving creative thinking skills and mastery of biological concepts of high school students, where students become more creative by simply connecting their prior knowledge with subsequent knowledge.

Abstract

Arthropods have many roles in an ecosystem, including as pest biocontrol agents. Spiders are part of a group of arthropods that carry out this function by being predators of insect pests. This research aims to analyze the diversity of spider types in the Lingsar District Vegetable Area, West Lombok Regency. Data was collected from January to April 2023 using a survey method with sweeping nets three times per week and pitfall traps every week on five routes (west, south, east, centre, and north). Identification of spider types is carried out referring to morphological characteristics, guided by the identification book. The samples obtained were analyzed using the Shannon-Weiner diversity index (H'). The research results showed that the spider species identified in the Lingsar Vegetable Area comprised 11 species belonging to 10 families. Zoropsis spinimana from the Zoropsidae family was found in all sampling lines and was the species with the highest number of individuals. The species with the lowest number of individuals found in only one route are Ctenus hibernalis (Ctenidae) and Cryphoeca silvicola (Cybaeidae). The diversity index ranges from 1.188-1.654 (medium category), with the highest diversity in the middle route. The list of names of spider types obtained has the potential to be used as a basis for developing biocontrol of agricultural pests using their natural enemies in the form of spiders on horticultural crops such as vegetables.
