Abstract

Pollinator insects are considered beneficial organisms due to their essential role in plant pollination, supporting both ecological stability and agricultural productivity. However, land-use change and pesticide application may reduce pollinator diversity, making it necessary to identify existing species and assess their diversity as indicators of ecosystem health. This study aimed to identify the species and assess the diversity of pollinator insects in Anagro Garden, Bengkulu City. Field research was conducted from January to March 2025 using an exploratory survey method combined with direct observation. Sampling was carried out across multiple points within the garden. The results showed that pollinator insects observed in this area belonged to four insect orders. The calculated Shannon-Wiener Diversity Index (H′) was 1.317, indicating a moderate level of species diversity. The Dominance Index (D) was 0.283, showing that no single order overwhelmingly dominated the assemblage. The Evenness Index (E) was 0.950, reflecting a high level of evenness and very uniform distribution of individuals among species. These findings suggest that although species abundances vary, the pollinator community remains balanced. The moderate diversity level indicates that the ecosystem quality in Anagro Garden is still fairly goodHowever, the study underscores the need for ongoing monitoring and habitat management to enhance pollinator diversity and maintain ecological resilience, particularly in semi-urban agroecosystems like those found in Bengkulu City.

Abstract

This study aims to determine the validity level of project-based Student Worksheets (LKPD) and to identify the practicality level of project-based LKPD in facilitating the learning independence of Grade X students at SMK Negeri 9 North Bengkulu. This research employed a Research and Development (RD) method using the 4D model, which consists of four stages: define, design, develop, and limited disseminate. The research subjects were Grade X students of a vocational high school. The research instruments included expert validation sheets and response questionnaires distributed to teachers and students. The collected data were analyzed using descriptive quantitative techniques with percentage calculations to determine the level of validity and practicality of the developed product. The results of the study indicate that the project-based LKPD obtained an average validity score of 94.67%, which falls into the very valid category. In addition, the practicality test results show that the project-based LKPD achieved an average score of 89.79%, categorized as very practical. These findings demonstrate that the developed worksheets meet the criteria of content feasibility, clarity of presentation, and ease of use in the learning process. Furthermore, the implementation of project-based LKPD encourages students to participate actively in learning activities, complete tasks independently, and develop problem-solving skills through project-based tasks.Therefore, it can be concluded that the project-based LKPD is feasible and practical to be implemented in classroom learning and can effectively facilitate the development of students’ learning independence

Abstract

This research was motivated by the low mathematical problem-solving ability of eighth-grade students at SMPN 15 Bengkulu Utara on the topic of linear equations and inequalities of one variable, as indicated by an average score of 40. In addition, the Student Worksheets (LKPD) used in the classroom are not contextual, less engaging, and have not optimally facilitated the development of students’ problem-solving skills. Therefore, this study aims to develop intercropping context-based LKPD that are valid and practical in facilitating students’ mathematical problem-solving abilities. This research employed a development research approach using the 4D model adapted into three stages, namely define, design, and develop. The study was conducted at SMPN 15 Bengkulu Utara. The research subjects consisted of 10 students of class VIII B in the limited trial and 23 students of class VIII A in the field trial during the 2025/2026 academic year. The research instruments included expert validation sheets as well as teacher and student response questionnaires. The collected data were analyzed using descriptive quantitative techniques through percentage calculations to determine the validity and practicality levels of the developed product.The results showed that the intercropping context-based LKPD obtained a validity percentage of 90.18% from experts, which falls into the highly valid category. Meanwhile, the practicality results indicated that the LKPD achieved a score of 93.33% based on teacher responses and 88.15% based on student responses, both categorized as highly practical. Therefore, the developed LKPD is considered valid and practical for facilitating students’ mathematical problem-solving skills.
