Abstract

This study aims to describe students' multi-representation ability in solving physics evaluation questions carried out by the qualitative description method in class X MIA 1 SMA Katolik St. Gabriel Maumere for the 2019/2020 school year. The data were obtained from the matter of physics evaluation on Newton's law material about the force of gravity. Data analysis is based on student work steps in solving evaluation questions. Data analysis results show that the ability of multi-representation in solving physics problems on Newton's law material about the force of gravity in the high category. The number of mathematical representations of 100%, image representation of 10%, then in the medium type only uses a mathematical description of 100% and in the low category using a mathematical representation of 100% and a verbal representation of 40%.

Abstract

Inflammation was signs of pathological or abnormality in tissue to give an alert as a trouble signal to the system. Therapeutic using NSAIDs has some side effects. This research explored the potential role of chlorogenic acid as natural therapeutic compound to inhibit the inflammation target such as COX-2 by interaction model. The research method used in this study was the molecular docking approach, which binds ligand and protein. Protein data provided by Protein Data Bank (ID: 6cox) while, chlorogenic acid obtain from PubChem (CID: 1794427). We docked COX-2 and chlorogenic acid using Hex 8.0.0. Visualization and analysis of the molecular interactions of chlorogenic acid and COX-2 conducted by the Discovery Studio Client 4.1 software. Chlorogenic acid has a high permeability and is easily absorbed based on five Lipinski Rule. Interestingly, we found Fifteen amino acid was binding with chlorogenic acid that formed by hydrogen bond and van der Waals.The interaction between ligand-protein results in energy binding -327.59cal/mol. Chlorogenic acid has a potential role to inhibit inflammation pathway by inhibiting COX-2. We predicted chlorogenic acid has a potential as therapy anti-inflammatory to suppress COX-2 as mediator inflammation.

Abstract

Coffee plants are one of the cultivated plants of the Sikka Regency community. Coffee contains chemical compounds which is needed by humans. One of them is cafeic acid. Cafeic acid was recognized as having the potential as an anti-inflammatory, antioxidant, and healing type 2 diabetes mellitus (T2DM). The Peroxixme proliferator-activated receptor gamma gene (PPAR-γ) has a role in homeostasis regulation, so it can be used as hyperglycemia. But do not study on the interaction of cafeic acid as anti-diabetes molecularly. The purpose of this study was to analyze and predict the physico-chemical properties and potency of cafeic acid as anti-diabetes through the interaction of cafeic acid with PPAR- γ protein in silico. The method used consisted of downloading PPAR-γ protein through protein bank data (GDP) and cafeic acid through the PubChem database, protein preparation (PPAR-γ) and ligands (cafeic acid) with the PyRx program, protein analysis and ligand using the program using the Hex program 8.0 .0 and Discovery Studio V16.1.0.15360. The results showed that occur between cafeic acid and PPAR-γ show the role of anti-diabetes. This is evidenced by the presence of 11 amino acid residues (ASP441, LYS373, ASP396, LYS438, GLU407, PRO398, GLY399, ARG397, LEU400, GLY395, VAL403) which interacted with the chlorogenic acids and their energies of -168.5cal/mol. This function activates GLUT2 and GLUT4 as transportation routes inside and outside the cell. Caffeic acid is predicted to have potential as a natural ingredient in coffee which can be used for DMT2 therapy with genetic care (Nurtigenetics). We suggest further study is required in vivo experiment.

Abstract

This study aims to describe the students' multi representation abilities in solving descriptive questions on straight motion material. This was qualitative research with an analytic descriptive approach. The subjects of this study were three physics teachers and twenty-five students of class X MIA SMA Negeri 1 Maumere. The data used in this study were evaluation questions, physical evaluation scores, student worksheets on evaluation questions and interview results. The data collection techniques used in this study were as follows: Documentation and in-depth interviews. For qualitative research data to be accounted for as scientific research, In this study, using triangulation techniques, checking data to the same source with different techniques, namely the results of observations, students' answers, and in-depth interviews. Data analysis techniques used in this study were grounded theory. The steps of grounded theory were: creating categories for the information obtained (open coding), selecting one of the categories and placing it in a theoretical model (axial coding), and then compiling a story of the relationship between these categories (selective coding). The results showed that students tend to use the same representation, such as verbal 12.5%, mathematical 87.5%, while graphics and pictures were 0%. For each category, students: (a) in the low category received a mathematical representation score of 73.81% and verbal representation was 83.3%, (b) in the moderate category received a verbal representation score of 85% and mathematically 83.06% (c) in the high category obtained a verbal representation score of 83.3% and mathematics 90.47%.

Abstract

Has be done research about the effect of Problem Based Learning model on students’ creative thinking abilityin SMAS Katolik St. John Paul II maumere. This type of research is a quasi experiment with the Nonequivalent Control Group Design. Sampling is done by nonprobability sampling technique, (class XI MIA 1 and class XI MIA), which is satueated sampling where all populations are sampled. The creative thinking ability of students in this study were collected with creative thinking ability test in the form of essay test consisted 10 items and observation sheets. The result showed that : 1) the average score of creative thinking ability from students who take learning using Problem Based Learning model are 73.80; 2) the average score of creative thinking ability from students who take learning with Expository Learning model are 65.97; 3) there are differences in creative thinking ability significantly between students who learn to use the Problem Based Learning model with students who learn to use Expository Learning model. Students who learned Problem Based Learning model show better think creative than who learned Expository Learning model. Thus, Proble, Based Learning model influences students creative thinking abilities.

Abstract

Sebutan Metode Feynman merujuk pada metode belajar yang diusulkan oleh fisikawan Amerika dan pemenang nobel fisika tahun 1965, Richard Feynman. Metode ini diklaim sebagai cara belajar yang dapat meningkatkan efisiensi dan efektivitas belajar siswa. Meski demikian, masih sangat jarang dijumpai penerapan metode ini dalam pembelajaran di kelas. Penelitian ini merupakan penelitian eksploratif yang bertujuan untuk mengetahui respons siswa terhadap penerapan metode Feynman dalam pembelajaran Fisika materi Impuls, Momentum dan Tumbukan. Respons siswa diperoleh lewat data yang dikumpulkan dengan menggunakan angket dan wawancara. Hasil respons siswa menunjukan bahwa lebih dari 50% siswa menyatakan setuju atau sangat setuju bahwa penerapan metode Feynman dapat membantu siswa dalam memahami materi yang dipelajari, menyelesaikan latihan soal yang diberikan, meningkatkan minat belajar dan melatih keterampilan berkomunikasi siswa. Dampak paling mencolok dari penerapan metode Feynman yaitu bahwa metode ini berperan secara signifikan dalam melatih keterampilan berkomunikasi siswa.

Abstract

This study aims to enhance the critical thinking skills and creativity of Class XI MIA students in static fluid material by implementing a problem-based learning model with contextual content. The research was conducted at SMAK Santa Maria Monte Carmelo Maumere, with the participants from Class XI MIA in the academic year 2023/2024. Data collection utilized tests to assess students's critical thinking skills and observations to evaluate creativity. The data analysis employed a descriptive quantitative approach. Research findings indicate that the average critical thinking skills score for students is 83, surpassing the minimum completeness criteria (KKM) set by SMAK Santa Maria Monte Carmelo Maumere. Additionally, the average creativity score for students is 68.75%, falling within the good category. These outcomes suggest that the implementation of the problem-based learning model with contextual content effectively enhances the level of critical thinking skills and creativity on Class XI MIA students in static fluid material.
