Abstract

This study aims to determine the effect of the combination of keji beling leaf extract (Strobilanthes crispus) and singkil leaf (Premna corymbose Rottl. et Willd) on the intensity of insect pest attacks on green eggplant (Solanum melongena L.). The study used a Randomized Block Design (RBD) with five treatments, namely control (water) and a combination of extracts at concentrations of 25%, 40%, 55%, and 70%, each repeated five times. The extract was made by maceration method using water as a solvent and additional natural adhesive (3 g detergent). Application was carried out twice per week, and the intensity of insect pest attacks was observed on days 11, 25, 39, and 53 DAP. Data were analyzed using ANOVA and the Least Significant Difference (LSD) test at a significance level of 1%. The results showed that the combination of extracts had a very significant effect on the intensity of insect pest attacks (F count > F table). The 70% concentration gave the lowest attack intensity, which was around 15%. This combination of extracts has the potential to be an environmentally friendly botanical pesticide for controlling insect pests on green eggplant plants.

Abstract

Facing future challenges requires various skills to achieve success, one of which is metacognitive skills. Therefore, the use of science-based learning in the learning process not only aims to improve student learning outcomes, but also to empower their metacognitive skills. This research aims to determine the effect of using Problem Based Learning (PBL) on the metacognitive and learning outcomes of class VIII students at SMP Negeri 37 Samarinda.  This type of experimental research uses quantitative methods in the form of a quasi experimental design type, the pretest posttest control group design. The population in this study were all class VIII students at SMP Negeri 37 Samarinda. Sampling used a purposive sampling technique using classes according to the researcher's needs with a sample size of 48 students. The instrument analysis technique uses construct validity and reliability tests, while the analysis of research results uses the N-gain test, normality test, homogeneity test, and Wilcoxon test with a significance level of 5%. The results of data analysis show that the average value of students' metacognitive indicators after being treated in the experimental class was 80.67 in the very good category, while the control class was 79.58 in the good category. The average posttest score for experimental class learning outcomes was 69.82, while the control class was 38.02. The N-gain metacognitive questionnaire test in the experimental class was 0.27 in the low category, while the control class was 0.08 in the low category. The experimental class had an N-gain value for the cognitive learning outcomes test of 0.46 in the medium category, while the control class was -0.01 in the low category. The Wilcoxon test results on the metacognitive questionnaire and learning outcomes show the Asymp value. Sig. (2 tailed) of 0.000, this value is smaller than 0.05 so it can be concluded that there is an influence of the use of Problem Based Learning (PBL) on metacognitive and cognitive learning outcomes of class VIII students at SMP Negeri 37 Samarinda on the human excretion system material.  Keywords: Problem Based Learning, Metacognitive, Learning Outcomes

Abstract

Student perception is their view and assessment of the experience and learning process in the classroom. This is important to study because the success of a learning model is also determined by how students interpret and respond to its implementation. This study aims to determine student perceptions of the implementation of the Project Based Learning (PjBL) learning model based on experiments with scientific articles as products in lower-level botany courses. This study is a quantitative descriptive study with an ex post facto approach using a survey method. Sampling was carried out using a purposive sampling technique on students of the Biology Education Study Program, Faculty of Teacher Training and Education, Mulawarman University. The data analysis technique used descriptive statistical analysis. The results of the data analysis show that the average result of all observed aspects obtained a percentage value of 84.99% which is included in the "very good" category, so it can be concluded that students of the Biology Education Study Program have a positive perception of the implementation of the Project Based Learning (PjBL) learning model based on experiments with scientific articles as products in lower-level botany courses. Therefore, these findings emphasize that the implementation of this learning model is worthy of being maintained and further developed with improvements, particularly in technical aspects and structured academic mentoring to optimize the quality of the learning process and outcomes.
