The main objective of this research was to find out whether the implementation of guided inquiry learning model can improve students' critical thinking skills on the reaction rate topic at one public school located in Central Sulawesi, Indonesia. Experimental research method was used in this study pretest-posttest design. Two science program classes at the grade 11 were recruited. Both were assigned as experimental class 1 and experimental class 2. To measure students' critical thinking skills, the instruments used were critical thinking skills tests and observation sheets. Findings suggest that the critical thinking skills of students in the experimental class 1 was 44% which was in the very high category, 36% of them included in the high category, and 20% included in the medium category. In contrast, in the experimental class 2, students' critical thinking skills were 52% and included in the very high category, 24% of them included in the high category, and 24% included in the medium category. In addition, the N-gain test showcased that the average value for experimental class 1 was 0.75 (the high category) and experimental class 2 was 0.77 (the high category). Our findings concluded that the guided inquiry learning model can improve students' critical thinking skills on the reaction rate topic.

This type of research was a true experiment with a non-randomized posttest two group design. The population of this research was all students of class XI MIA, the sampling techniques was saturated sampling methods. The sample used was students of class XI MIA 1 and XI MIA 2 as experimental class 1 and experimental class 2. The testing of students’ learning outcomes data was using one-party statistical analysis t-test to test the completeness of individual learning outcomes and classical completeness test to test the overall percentage of mastery learning. The results of data analysis obtained, the mean experimental class 1 (X1) was 75.5 with a standard deviation of 10.71 and the average experimental class 2 (X2) was 76.43 with a standard deviation of 12.77. The results of hypothesis testing with one-party t-test statistics in the experimental class 1 and 2 was obtained tcount > ttable (2.321 > 1.740; 2.306 > 2.101) with a significance level of α = 0.05 and degrees of freedom 18 and 19, then H0 was rejected and Ha was accepted. Then, the result of the classical completeness test obtained in the experimental class 1 were 80% and experimental class 2 were 80.95%. Based on the results of data analysis it can be concluded that the problem-solving learning model is effective against students’ learning outcomes in the acid-base solutions topic in SMA Negeri 1 Buko on Academic Year 2018-2019.

Cocoa beans husk is waste produced from the cocoa processing industry containing alkaloid, flavonoid, tannin, saponin, and triterpenoid compounds. This material has the potential to be used as a source of natural antioxidant compounds. This study aimed to determine the antioxidant activity of cacao beans husk extracts by comparing acetone and ethanol as solvents through the extraction process. This antioxidant activity was determined using the DPPH (1,1-diphenyl-2-picrylhydrazyl) test method measured by UV-Vis spectrophotometer after adding an extract of cocoa beans husk. The positive control was vitamin C, while the negative control was DPPH solution dissolved in ethanol. The results showed that the extract of cacao beans husk has more potent antioxidant activity with a lower IC50 value of 181.2 ppm, while the acetone extract has an IC50 value of 247.9 ppm

This Study aims to analyze and describe the effectiveness of Online Learning during the Covid-19 Pandemic on Motivation and learning outcomes of Students’ SMA Negeri 1 Ampibabo. The Research Method used was Descriptive Quantitative Research. The Subjects of this study consisted of 2 teachers and 171 students. The data collection instruments used were assessment data, interview texts and learning motivation questionnaires. Based on the research and analyze of interviews showed that online learning during Covid-19 pandemic is still less effective in improving Students’ learning than face-to-face learning. It was shown in the average value of learning outcomes before the pandemic (226.23) which was higher than the average value of learning outcomes during the pandemic (117.77). in addition, it was also found that level of students’ motivation toward online learning was in the positive category with a doubtful attitude, namely 67,34%. The students need to be accustomed to accessing the internet a lot, especially on online learning applications so that students can be trained to use applications when learning so, online learning process becomes effective during the Covid-19 pandemic.
