Abstract

This study addresses the persistent challenge of rice storage and food security, focusing on the post-harvest management of stored grains, particularly in mitigating damage caused by the rice weevil (Sitophilus oryzae L.). The research explores the impact of varying concentrations (2-8 grams) of green betel leaf (Piper betle L.) powder extract on rice weevil mortality. Employing a Completely Randomized Design, the study reveals that the highest mortality (15.6%) is achieved with an 8-gram concentration of green betel leaf powder. Correlation analysis establishes a positive relationship between concentration and weevil mortality (r = 0.84), with a significant correlation (r = 0.77) between concentration and the time taken for weevil mortality. Calculated efficacy demonstrates that the 8 gram concentration achieves a 70% effectiveness, meeting success criteria. Consequently, green betel leaf powder emerges as a promising botanical insecticide against rice weevils, warranting further investigation for dosage optimization and concentration. Future research should prioritize environmental and human safety considerations in the development and application of botanical insecticides in agricultural pest management.

Abstract

This research aims to identify high school students' misconceptions regarding motion and force using the Force Concept Inventory (FCI) instrument. This study used a quantitative method with respondents of 108 students in class XI science. Misconception data was obtained using FCI in the form of multiple-choice questions. There are 30 questions with five options. The results showed that a total of 46 out of 108 students (19.44%) answered 8 to 11 questions correctly, 41 students (37.96%) answered 5 to 7 questions correctly and the other 21 students (42.59%) only answered 2 to 4 questions correctly. The conclusion is students had misconceptions about the concepts of motion and force, especially on topics such as kinematics, Newton's laws, the principle of superposition, and kinds of force. This research implies the importance of understanding students' misconceptions in developing physics curricula and learning strategies in high schools. It is hoped that the research results can provide information to teachers about students' conceptual understanding so that appropriate learning strategies can be developed to correct students' misconceptions in learning.

Abstract

This study aims to evaluate the impact of the CTL model on cognitive and learning activities of fifth-grade students at SDN 16 Banda Aceh, particularly when their cognitive scores in heat transfer topics in science do not reach the minimum threshold (KKM) of 76. This quantitative research uses a one-shot case study design with measurement and observation sheets as instruments. The analysis shows that the average student score before using the CTL model was 80.76 with 72.73% classical completeness, and after using the CTL model, it was 76.33 with 69% classical completeness. Hypothesis testing indicated t count > t table (2.49 > 1.69), thus H1 is accepted. Average cognitive scores were C1 = 22, C2 = 27, and C3 = 31. The instructor's task average score was 4.74 (very good), and student learning experiences were 85% very good, 9% good, and 6% acceptable. The results indicate that the CTL model positively affects individual cognitive outcomes with an average score of 80.76. However, it does not significantly impact the percentage of classical completeness, which remained at 72.73%, below the required 80%. The CTL model enhances teacher and student learning experiences, making students more engaged and enthusiastic as the learning connects directly to their lives.

Abstract

Population increase has an impact on the procurement of food sources. Pakcoy is a vegetable that is in increasing demand. Farmers' response to this condition is to use excessive fertilizer and pesticides, thereby reducing soil fertility. The research aims to obtain a combination of fertilizer and humic acid, which is effective in cultivating B. rappa chinesis L., as well as soil conservation efforts. The methodology was experimental with Randomized Block Design (RBD) on four treatments, K, P1, P2, and P3. The dose of K was 150 g/5 m2, NPK 16:16:16, 1 kg/5 m2 dolomite, and 5 kg/5 m2 manure. The P1 treatment is the same as K but without NPK fertilizer. P2 and P3 treatments were reduced by 50% and 70% of NPK fertilizer, respectively, with the addition of humic acid. The research results show that P2 with local environmental conditions provides optimal results in terms of chlorophyll, stomata, and plant height. Soil fertility was shown by increasing pH to 6.6, K 281 ppm and P 509 ppm, Cation Exchange Capacity (CEC) 31.60 cmolc/kg, soil enzymes of 0.12 mg FDA g-1 soil d.w. h-1, an average number of earthworms of 17. The conclusion is that P2 fertilizer formulation can be applied to cultures as an anticipation of food security.

Abstract

The research was carried out based on facts found in the field regarding the science and science learning process which still lacks teaching materials. The lack of teaching materials or media used in learning causes learning in class to become less active. Apart from that, teachers also do not use learning models that improve students' ability to think critically, which results in students being less active in class. This research uses the ADDIE Model which consists of five steps, namely analysis, design, development, implementation and evaluation. The results obtained from this research are E-Modules based on the Guided Inquiry Learning Model which are valid, practical and effective. The product validity results obtained from three experts, namely media experts, material experts and language experts respectively were 90.38 %; 91.67%; and 100% with a very valid category. In terms of product practicality, the E-Module is in the very practical category with teacher response practicality results of 88.33 % and student response practicality results of 88.35%. The effectiveness results obtained in this research also show that the product developed is very effective for use in the learning process.
