Abstract

This research aims to analyze the contextual teaching and learning (CTL) model on students' creative thinking skills on the reaction rate topic. This quantitative research used true experimental design of pretest-posttest control. The samples used in this study were from 11th grade at SMA Negeri 1 Pinolosian. The experimental class sample was given treatment of the CTL learning model while the control class used conventional learning, respectively, were 31 and 30 students of 93 populations. Based on a questionnaire, students' creative thinking skills were obtained through observation during the learning process. The data analysis of the test instrument was carried out through a validity test using the product-moment correlation technique (significant level = 0.05), Lilliefors normality test, homogeneity of variance test and ttest. The CTL implementation questionnaire and instrument test data were converted into percentages and categorized. The results showed that the application of the CTL model had a positive effect on students' creative thinking abilities, evidenced by the average score of students in the experimental class before and after treatment increased from 14.55 to 74.84. Otherwise, in the control class, the scores were 30.59 to 33.56. The percentage of students' achievement in creative thinking aspects in the experimental class was good (61%-80%) while the control class was less good (21%-40%). The creative thinking abilities of both classes are very different, which is also reflected in the learning outcomes. The value of tcount (2.240) was greater than ttable (2.042) at the significant level = 0.05, and the hypothesis of H0 was rejected, or H1 was accepted. The application of the CTL learning model positively influenced students' creative thinking skills on the reaction rate material. Students' low originality abilities compared to fluency, flexibility, and elaboration abilities were also discussed.

Abstract

This study aims to determine the protein content and activity of nike fish (Awaous melanocephalus)  extract as an antioxidant. Nike fish (amphidromous goby larva) is an endemic fish of Gorontalo which is consumed as food and contains minerals, fats, carbohydrates, amino acids, and high protein. Nike fish extract uses a buffer with several components such as water, Tris HCl 0.1 M pH 8.3, NaCl 2 M, CaCl 0.01 M, 2-Mercaptoethanol 1%, and Triton X-100 0.5%. Based on qualitative analysis, Nike fish protein extract was positive through biuret, ninhydrin, xantoproteate, and Pb sulfide tests. Judging from the quantitative analysis, nike fish extract using the biuret method using UV VIS and TVB-N spectrophotometers obtained 47.60% and 0.098%, respectively. The antioxidant activity of nike fish extract using the DPPH method (1,1-diphenyl-2-pycryhydrazyl) was 20.29 mg AEAC/g (Ascorbic acid Equivalent Antioxidant Capacity). IC50 (Inhibitory Concentration) is 520 ppm at low levels but has potential as an antioxidant.

The purpose of making corn milk is to determine the amount of sucrose content and the effect of adding water in making corn milk to the level of consumer acceptance through organoleptic tests which include color, aroma, and taste with the addition of 200 ml of water (treatment 1), 250 ml (treatment 1). 2), and 300 ml (treatment 3). The method used in this study is the Carbohydrate test (Luff Schoorl) and experiments. The analysis used is the Anova test. The purpose of this study was to determine the amount of sucrose content in corn milk and how the effect of adding water was 200 ml, 250 ml, and 300 ml. The results showed that the amount of sucrose contained in corn milk with the addition of 250 ml of water was 2.90% and the highest level of acceptance was, for the organoleptic taste test, namely in treatment 2 with the addition of 250 ml of water and 3 with the addition of 300 ml of water with the results percentage of 40%, for the aroma organoleptic test, namely in treatment 2 with a presentation result of 40%, and the last color organoleptic test was treatment 2 with a presentation result of 68%. Corn milk with with 250ml water added has 2,90% sucrose and it is acceptable based on standard.  ABSTRAK  Susu nabati seperti susu jagung sangat penting untuk kesehatan, terutama bagi seseorang yang alergi terhadap susu sapi.

Abstract

COVID-19 is a disease that caused a prolonged pandemic in many countries caused by the SARS-CoV-2 virus. This study aims to identify the antiviral potential of secondary metabolites in Gorontalo traditional medicinal plants, which are believed to have the ability to inhibit the main protease protein of this virus. The methods used in this research were molecular docking and molecular dynamic. The main protease proteins for SARS-CoV-2 used based on the homology modeling results were 3V3M and 7TE0. The results of the active compounds in the paxlovid drug were also compared to obtain accurate data comparisons. The validation of the docking method on the 3V3M protein using the natural ligand 0EN revealed an RMSD of 0.75 Å. The RMSD value for validating the 7TE0 protein and natural ligand 4WI was 1.65 Å. The best molecular docking results were obtained using physalin F with a binding affinity of −10.3 kcal/mol for the 3V3M protein and physalin J with a binding affinity of −8.9 kcal/mol for the 7TE0 protein. The outcomes of the molecular dynamic method on the best complexes were determined by examining the value of changes in system energy, changes in system temperature, changes in system pressure, RMSD, RMSF, and bond-free energy (ΔG) of the complex. The standard 0EN ligand had a ΔG of −26.53 kcal/mol, while the standard 4WI ligand had a ΔG of −47.16 kcal/mol. The ΔG of the 3V3M-physalin F and 3V3M-physalin J complexes were respectively −28.22 kcal/mol and −26.62 kcal/mol. The ΔG of the 7TE0-Vitexin 2”-O-gallate and 7TE0-physalin J complexes were found to be −28.08 kcal/mol and −26.62 kcal/mol, respectively. The ΔG produced in paxlovid with complexes 3V3M and 7TE0 was −19.38 kcal/mol and −25.44 kcal/mol, respectively. Physalin F, physalin J, and Vitexin 2”-O-gallate have great potential to become SARS-CoV-2 inhibitor agents. However, in terms of structural stability and binding-active residues, these three compounds do not outperform the active substance in paxlovid.

Abstract

The aim of this research was to investigate the interaction between secondary metabolite compounds and the Mpro receptor, which was the main protein in Covid-19. Ligand-receptor interactions were studied using the Molecular Docking method. The validation results indicated that the test ligand Andrographolide had a higher affinity value compared to the standard ligand, with a value of -6.6 kcal/mol compared to the standard ligand's -7.5 kcal/mol. Additionally, the compound 14-Acetyl-3,19-isopropylideneandrographolide, 5,4 dihydroxy-7,8,2',3'-tetramethoxyflavone-5-glucoside had an affinity of -7.5 kcal/mol, Andrographidin A had -7.6 kcal/mol, Andrographiside had -7.7 kcal/mol, Skullcapflavone I had 7.7 kcal/mol, 5-Hydroxy-7,8,2'-trimethoxyflavone-5-glucoside had -7.7 kcal/mol, Apigenin had 7.7 kcal/mol, 5-Hydroxy-7,8-dimethoxyflavone-5-glucoside had -7.8 kcal/mol, Neoandrographolide had -7.8 kcal/mol, Andropanoside had -7.9 kcal/mol, Wogonin-5 glucoside had -8.1 kcal/mol, 5,2',3'-Trihydroxy-7,8-dimethoxyflavone-3'-glucoside had -8.4 kcal/mol, and Bisandrographolide had -8.5 kcal/mol. From the molecular docking results, the secondary metabolite compounds from the Andrographis paniculata plant exhibited significant interactions surpassing the standard ligand N3. Active residue interactions observed included Phe140, Leu141, Asn142, Gly143, His163, Glu166, Gln189, and Thr190. Keywords: Andrographis paniculata; Covid-19 drug; Mpro receptor; molecular docking
