Abstract

This study aims to develop an ebook that is integrated with a Learning Management System (LMS) to improve students' metacognition skills. The research uses the ADDIE development model (Assumption, Design, Development, Implementation, Evaluation). The research data were obtained from 40 students who filled out the questionnaire and took the pretest and posttest. The effectiveness of the ebook on improving metacognitive skills used N-Gain analysis and to determine the difference between the experimental and control classes, a T-test was performed, using One Group Pretest and Post-test Design. The results showed that ebook development was very good. The development of ebooks integrated with LMS can significantly improve students' metacognitive abilities. Thus, this study recommends that lecturers use ebooks that are integrated into the learning management system so that learning can run effectively to improve students' metacognitive abilities.

Abstract

This study aims to investigate the effectiveness of implementing the Learning Cycle 7E model assisted by educational games in improving the learning outcomes of class XI F students at SMA Negeri 2 Palu. The research method applied is Classroom Action Research (CAR), which was conducted in two cycles with a total of 36 student participants. Each cycle consisted of four stages: planning, implementation, observation, and reflection. The material in the first cycle focused on “structure, function, and hormones in the human reproductive system,” while the second cycle discussed “menstruation, fertilization, gestation, and disorders of the human reproductive system.” Data collection was carried out through learning achievement test instruments in the form of pretests and posttests, and the data were analyzed using the percentage of learning mastery. The results revealed that in the first cycle, student mastery increased from 22% (pretest) to 89% (posttest). In the second cycle, the mastery level rose from 17% to 92%. These findings indicate that the implementation of the Learning Cycle 7E model is effective in science learning and has a significant impact on improving student achievement. Overall, it can be categorized as producing a very high level of mastery, proving the potential of integrating the Learning Cycle 7E with educational games in classroom practice.

Abstract

This study aims to improve student learning outcomes in Biology through the application of the Joyful Learning approach supported by Wordwall interactive media. The method used in this study was Classroom Action Research (CAR) conducted in two cycles and involving 34 students of class XI SMA Negeri 2 Palu as research subjects. Each cycle of this study included the stages of planning, implementation, observation, and reflection. Data were obtained through observation sheets and learning outcome tests, then analyzed descriptively by considering the average score and percentage of classical mastery. The results showed that in the pre-cycle stage, student learning mastery only reached 41.18% with an average score of 70.00. After the action in cycle I was implemented, mastery increased to 67.65% with an average score of 76.35. A further improvement in cycle II resulted in a significant increase, namely 88.24% mastery with an average of 81.56. Thus, the application of the Wordwall-based Happy Learning approach proved to be effective in creating a conducive learning atmosphere, increasing student participation, and encouraging more optimal understanding of the material.

Abstract

This study aims to describe the integration of the Flipped Learning approach in fostering students’ learning autonomy in Grade XI Biology at SMA Negeri 2 Palu, particularly on the topic of the Human Reproductive System. The research subjects consisted of 35 students. The study was conducted as Classroom Action Research (CAR) over two cycles, each comprising two meetings. Data were collected through teacher and student activity observations, formative tests, and student reflections, and analyzed using both quantitative descriptive and qualitative methods. The findings reveal that the percentage of teacher activity increased from 70% and 75% in cycle I to 85% and 95% in cycle II, while student activity increased from 50% in both meetings of cycle I to 72.5% and 85% in cycle II. Students’ average formative test scores also improved from 58.1% and 62.7% in cycle I to 76.3% and 83.9% in cycle II. Student reflections indicated enhanced motivation, active participation, and readiness for independent learning. These findings suggest that science learning through the Flipped Learning approach can foster students’ learning autonomy while simultaneously facilitating critical thinking skills and the effective use of technology required to meet the challenges of 21st-century education.

Abstract

This study aimed to identify the morphological types of microplastics present in the digestive tracts of squid (Loligo sp.) sold at a traditional market in Palu City. A descriptive approach combining quantitative and qualitative analyses was employed. A total of 10 fresh squid specimens were randomly selected from a single vendor at Lasowani Traditional Market. The digestive tracts were isolated, digested using 10% potassium hydroxide (KOH), and incubated at 40°C for 96 h. The recovered particles were subsequently classified and counted, and microplastic abundance was calculated. Three morphological types of microplastics—fibers, films, and fragments—were detected in the digestive tracts of the 10 squid specimens. A total of 948 particles were recorded, corresponding to a mean abundance of 94.8 particles per individual. Films were the most prevalent type, accounting for 48.4% of the total particles, followed by fragments at 26.7% and fibers at 24.9%. These findings indicate that film-type microplastics were dominant in the digestive tracts of the examined squid. Based on the research findings, an educational poster was also developed and subjected to expert validation. The poster achieved a feasibility score of 82.23%, indicating that it was highly suitable, based on the validation results, for use as a learning resource in biology education.

Abstract

This study aimed to determine the phylogenetic relationship of coral trout groupers (Plectropomus spp.) in the waters of Liang Village, Banggai Kepulauan Regency, based on morphological characters. The research employed a descriptive exploratory method with quantitative and qualitative approaches. Samples were collected using purposive sampling, obtaining 15 individuals representing five species: Plectropomus leopardus, Plectropomus oligacanthus, Plectropomus maculatus, Plectropomus areolatus, and Plectropomus leavis. Morphological observations included 25 morphometric characters, 11 meristic characters, and 4 qualitative characters. Data were analyzed using Principal Component Analysis (PCA) to identify the main morphological characters contributing to variation among species, followed by cluster analysis using the Unweighted Pair Group Method with Arithmetic Mean (UPGMA) to assess phylogenetic relationships. The results indicated that the physicochemical conditions of the waters in Liang Village were suitable to support coral trout grouper populations. PCA results showed that the first two principal components (PC1 and PC2) explained 73.31% of the total morphological variation, with interorbital length, dorsal fin base length, and body depth contributing most significantly to species differentiation. The UPGMA dendrogram revealed that Plectropomus leopardus exhibited the closest phylogenetic relationship with Plectropomus areolatus and Plectropomus oligacanthus, while Plectropomus maculatus showed the greatest morphological divergence and formed a separate cluster. These findings demonstrate that morphological characters are effective in revealing phylogenetic relationships among Plectropomus species in the studied waters.
