Abstract

This study investigates the effectiveness of the Project-Based Learning (PjBL) model integrated with Liveworksheet media in enhancing the critical thinking skills of vocational high school students. Employing a true experimental design with a pretest- posttest control group approach, the research compared two groups: the experimental group using PjBL with Liveworksheet and the control group receiving conventional instruction. Data collected from pretest and posttest assessments revealed that the experimental group demonstrated a significant improvement in critical thinking skills, with an average posttest score of 81, compared to 64 in the control group. The pretest scores showed no significant differences between the groups, indicating a similar starting point. Post-intervention results were analyzed using statistical tests, confirming the normal distribution and equal variances of data. The hypothesis testing further validated a substantial difference in critical thinking skills, favoring the PjBL model with Liveworksheet media. These results underscore the effectiveness of this innovative teaching approach in fostering critical thinking skills among vocational students

Abstract

The protected forest of Londerang Jambi is an area of hydrological unity with a surface area of 12.484 ha that is located in the district of Tanjung Timur and Muaro Jambi, which is surrounded by palm plantations and forest of industrial crops and 10 villages in the Districts of Tanjung Jabung Timur and Jambi. Based on the results of the Landsat 8 OLI image analysis and the SPOT 7 image interpretation by WWF Indonesia in 2015 that the Londerang Forest Protection Area (HLG) has an area of 12.848 Ha, currently the steep vegetation cover that canopies closely on the HLG Londerang remains only less than 10% of the area of HLG londerang due to forest fires in 2015. An attempt to overcome the situation has been made, one of them in the HLG Londerang being made an of the Hydrological Union of Mendahara-Sungai Batanghari which has been intervened by the Badan Restorasi Gambut (BRG). This effort was also carried out by the KIFC (Korea Indonesia Forest Center) by revegetating the blocks of land that had been burned in HLG Londerang. The planting has been carried out from the beginning of 2022 to December 2022. The species of plants planted among them are Pulai Rawa (Alstonia scholaris), Balangeran (Shorea balangeran), Gelam (Melaleuca leucadendron). In order to support the success of the revegetation, intensive maintenance is required, including the provision of soil fertilizers such as dolomite and NPK fertilizer. The research was conducted for seven months from May to December 2023 at HLG Londerang. Measuring fields are made with group random designs (RAK). The clustering is based on the difference in the height of the groundwater surface

Abstract

The learning outcomes of students' science content are still low. The minimum completeness criteria (KKM) of 70 is not met by most students who take the class IV test. This is because students do not want to participate in learning because learning activities are still dominated by lectures. The purpose of the study was to improve the learning outcomes of science material on changes in the form of objects based on the problem. Data from 27 fourth grade students were collected and presented using an experimental approach. There were two cycles when the research was conducted in the even semester of the 2022/23 academic year. Planning, implementing, observing, and reflecting are part of the research procedure. In terms of pre-cycle learning results, the average benefit of learning outcomes reached 60 or 33%, the first cycle benefited the average learning outcomes reached 72 or 67% of students mastered the learning completely while the second pattern increased. student learning outcomes increased to 83 or 92.5% of students achieved learning authority. Therefore, the material changes in the form of objects in class IV SDN 1 Kertaraharja can be improved by the experimental method.

Abstract

This article analyzes the use of data mining with Naïve Bayes and K-Nearest Neighbor (KNN) algorithms to build classification models and evaluate their performance in identifying fishermen eligible for aid. The study aims to compare the effectiveness of these algorithms in handling imbalanced datasets using the Synthetic Minority Over-sampling Technique (SMOTE). The research applies SMOTE to improve the balance of the dataset before classification. Without SMOTE, Naïve Bayes achieved an accuracy of 97.01%, precision of 94.16%, recall of 96.67%, and F1-score of 95.39%. KNN, on the other hand, reached an accuracy of 94.04%, precision of 94.53%, recall of 86.00%, and F1-score of 90.06%. After applying SMOTE, both algorithms improved: Naïve Bayes attained an accuracy of 98.33%, precision of 96.86%, recall of 100.00%, and F1-score of 98.49%, while KNN reached an accuracy of 96.90%, precision of 97.72%, recall of 96.19%, and F1-score of 96.94%. The results show that Naïve Bayes, with SMOTE, outperforms KNN in managing data imbalance and accurately classifying eligible fishermen for aid.

Abstract

Anemia is a significant health issue with serious consequences, including increased maternal and infant mortality and reduced performance in various activities. In pregnant women, nutritional anemia not only jeopardizes the mother's health but also affects fetal development and pregnancy outcomes. This study aimed to assess the effectiveness of consuming Moringa leaves and dates in increasing hemoglobin levels in pregnant women with anemia. A quasi-experimental design with a pre-test and post-test was used, involving 210 pregnant women divided into two groups. Group 1 received Moringa leaves and Fe tablets, while Group 2 received dates and Fe tablets, with interventions lasting 30 days. Initial tests showed moderate anemia in both groups. After the intervention, significant improvements in hemoglobin levels were observed in both groups. However, the combination of dates and Fe tablets proved more effective than Moringa leaves and Fe in raising hemoglobin levels. The findings suggest that both Moringa leaves and dates are effective in combating anemia in pregnant women, with dates showing slightly better results.

Abstract

This research aims to develop a teaching module based on RME that is valid, practical, and effective for class VII SMP, with a focus on improving the ability to solve problems with mathematical students. We developed the modules by considering the local context and culture, adhering to RME measures, and emphasizing the use of relevant and conceivable situations for students. We utilized the Plomp development model, which encompasses the stages of investigation, creation, and evaluation. We tested the prototype and assessment of this teaching module on participants enrolled in class VII at SMP N 1 Ranah Batahan. The research results demonstrate that the developed teaching modules have high validity (89.33%), practicality (89.60%), and proven effectiveness, as evidenced by an average score of 85.50% among the test study students.  In addition to enhancing the mathematical skills of students, the RME approach also enhances the study of IPAS (Natural and Social Sciences). The development of problem-solving and critical thinking skills through this module enhances students' understanding of natural and social phenomena. Therefore, this teaching module not only promotes mathematical achievement but also fosters integrative and holistic learning within the framework of IPAS.
