This study is part of a development of problem solving learning model with aspects of ontology, epistemology, and axiology (Model PS-TRILOGI) to improve critical thinking skills and student understanding of Thermochemistry concepts. These objectives can be achieved if the model PS-TRILOGI is valid, practical, and effective. The study design followed the Research and Development. The effectiveness of the model PS-TRILOGI assessed by observers and implemented through the instrument test critical thinking skills and understanding of Thermochemistry concepts at 33 students in Chemistry Education Studies of Tadulako University. The results obtained showed that the percentage of positive responses given by students is very high due sense of excitement, novelty, interest, and support learning media are respectively 94.95%; 90.91%; 90.91% and 96.97%. Indicators that measure critical thinking skills is the interpretation, analysis, inference, and self-regulation. N-gain value for the indicator interpretation, analysis, and self-regulation in middle category of 0.5; while indicators inference at the high category of 0.7. Understanding of the Thermochemistry concept 13 students has a value n-gain of 0.8 to a high category. Based on the results obtained show that the model PS-TRILOGI is effective.

Phaleria macrocarpa contains secondary metabolite compounds such as alkaloids, terpenoids, saponins, polyphenols, tannins, sterols, and coumarins. Those metabolites are antioxidants and can be efficacious in the healing of various degenerative diseases such as cervical cancer and diabetes. This plant is widely grown in Tindaki Village, Parigi Mautong, Central Sulawesi. The aim of this study was to determine the antioxidant power of those phaleria macrocarpa fruit extract. This study was conducted by using maceration extraction technique with ethanol as solvent, and compound 2,2-difenil-1-picrilhidrazil (DPPH) as source of free radical, and vitamin C as the positive control. The UV-Vis spectrophotometer was used to measure the absorbance of the extract. Various concentrations of the extract used were 5 ppm, 15 ppm, 25 ppm, and 35 ppm. The results showed that the IC50 value of the fruit extract was 28.242 ppm, while the IC50 value of vitamin C was 19.302 ppm. These IC50 values show that vitamin C was a stronger antioxidant activity than the fruit extract, but the fruit extract was still as a very strong natural antioxidant category.

Misconception is a conception of someone who is not in accordance with the scientific concept recognized by experts. Student’s who experience misconceptions will make mistakes in understanding concept’s and occur continuously. This study aimed to determine the percentage of reduction of students’ misconception in grade XI SMA 1 Palasa on salt hydrolysis by implementing contextual teaching and learning (CTL) approach. This study was a quantitative descriptive study with the number of samples of 2 classes, that’s Class XI Science A consisted of 22 students, and Class XI Science B consisted of 22 students. The instrument test was a reasoned multiple choice test accompanied by a certainty of response index (CRI) consisting of 20 items. The results showed that the percentages of the average reduction of students’ misconceptions in the class XI science A and in the class XI science B on salt hydrolysis with contextual teaching and learning (CTL) approach were 19.6 and 9.8%, respectively.
