Abstract

This study aims to determine the perception of high school students in Indonesia towards chemistry, as well as to see the relationship between learning difficulties with interest, motivation, and teacher factors. The survey was conducted online with a google form with a cross-sectional survey design and snowball sampling technique. The number of respondents involved in this survey was 412 respondents. The results of the analysis showed that chemistry is included in the difficult category with an average percentage of 65.30%. However, when viewed from the aspect of interest, chemistry is a subject of interest with an average percentage of 71.02%. Furthermore, in terms of motivation, it can be seen that students are quite motivated to learn chemistry with an average percentage of 53.84% and in terms of teachers, it can be seen that teacher factors influence students' perceptions of chemistry with an average percentage of 52.80%. The results of the correlation analysis of the four aspects observed obtained information that there was no relationship between learning difficulties in chemistry with interest, motivation, and teacher factors. However, there is a positive relationship between interest in chemistry with learning motivation, and motivation to learn chemistry with teacher factors. So it can be concluded that although chemistry is considered a difficult subject, it is still in demand by students.

Abstract

Critical thinking skills require a fundamental understanding of content in order to understand, analyze, and evaluate information. Therefore, learning critical thinking skills requires a good combination of student-centered learning and teacher-centered learning. One such student-centered learning approach is Project-Based Learning (PjBL). The purpose of this study was to determine the differences in critical thinking skills of students who learn chemistry using innovative project-based learning and those without innovative project-based learning. The sample in this study was students of class XII MIPA 3 (Control Class) and class XII MIPA 4 (Experimental Class) of SMA Negeri 3 Solok. Based on the test results, it was found that there were differences in critical thinking skills between students who learned chemistry using innovative project-based learning and those without innovative project-based learning. Where the results of the Independent Samples Test - T showed that the p-value was > 0.05. So it can be concluded that the critical thinking skills of students who learned chemistry using innovative project-based learning were better than those without innovative project-based learning.

Abstract

Tomato (Lycopersicum esculentum L.) is a horticultural crop of considerable economic importance, valued for its nutritional and functional properties. Despite its potential, enhancing tomato productivity remains a critical challenge. This study aims to evaluate the effectiveness of integrated fertilizer application and to determine the optimal dosage of the combination of goat manure bokashi and banana peel–based liquid organic fertilizer (POC) on the vegetative growth and fruit yield of tomato plants. The experiment was conducted from April to July 2024 in Supayang Village, Payung Sekaki District, Solok Regency, West Sumatra Province, situated at an elevation of 700 meters above sea level. A Randomized Block Design (RBD) was employed, comprising six treatment groups and four replications. The treatments included: PO (control), P1 (bokashi 20 tons/ha + POC 120 ml/L), P2 (bokashi 20 tons/ha + POC 170 ml/L), P3 (bokashi 20 tons/ha + POC 220 ml/L), P4 (bokashi 20 tons/ha), and PS (POC 220 ml/L). Statistical analysis revealed that the integrated application of goat manure bokashi and banana peel POC significantly influenced plant height, stem diameter, days to 50% flowering, harvest time, and fruit count per plant. However, no statistically significant effect was observed on fruit weight per plant across the treatments.
