Abstract

Critical thinking skills are a key component required in completing independent tasks (Sukenda, 2016). This study aims to analyze correlation between students' critical thinking skills and the quality of independent assignments in Histology courses. The research method used was a correlational quantitative approach involving 35 Biology Education study program students who were taking Histology courses. Data were collected through a histology context-based critical thinking test and independent assignment assessment using an analysis rubric. The correlation test results showed a positive correlation between critical thinking skills and the quality of students' independent assignments (r = 0.244, p < 0.05). This finding indicates that although there is a positive correlation coefficient between critical thinking ability and independent assignment quality, the significance value (Sig.) of 0.157 indicates that the correlation is not statistically significant. Based on this data, it can be concluded that there is no significant correlation between students' critical thinking skills and the quality of their independent assignments in the Histology course.

Abstract

The inefficient implementation of learning approach and method can make student participant less active and leads to lack of critical thinking skills. This study aims to determine the effect of the deep learning approach using mnemonics on the critical thinking skills of seventh-grade students regarding the classification of living organisms at SMP Negeri 46 Samarinda. This study employed a quasi-experimental research design with a non-equivalent control group design. Sampling was conducted using purposive sampling, with a sample size of 25 students each for the experimental and control classes. The data analysis techniques used are N-Gain test and the Independent Sample T-Test. The results of the data analysis showed that the N-Gain score for critical thinking skills in the experimental class, with an average of 0.74, fell into the high category, while that of the control class, at 0.60, fell into the moderate category. The hypothesis results showed a significance value (2-tailed) of 0.000 for critical thinking skills, where this significance value (2-tailed) was < 0.05 so it can be concluded that there is an effect of the deep learning approach using mnemonics on the critical thinking skills of seventh-grade students regarding the classification of living organisms at SMP Negeri 46 Samarinda.

Abstract

The armyworm is a major pest that can reduce crop yields. Control using chemical pesticides carries the risk of causing health problems, environmental pollution, and pest resistance. Therefore, safer and more environmentally friendly alternatives in the form of botanical pesticides are needed. This study aims to determine the effect of a combination of soursop leaf extract (Annona muricata L.) and PGPR (Plant Growth Promoting Rhizobacteria) from bamboo roots (Gigantochloa apus) on the mortality of armyworms (Spodoptera litura) on green mustard plants (Brassica juncea L). The experimental design used was a randomized block design (RBD), consisting of 8 treatments and 4 replicates, resulting in 32 experimental units. The results showed that soursop leaf extract and PGPR from bamboo apus roots, at an optimal concentration of 70%, significantly increased armyworm mortality to 85%.
