Bima ethnic medicinal plants as a natural hand sanitizer Mahrun Mahrun; Mujiono Sang Putra
Jurnal Pijar Mipa Vol. 17 No. 3 (2022): May 2022
Publisher : Department of Mathematics and Science Education, Faculty of Teacher Training and Education, University of Mataram

This study aims to identify potential ethnic plants with medicinal properties in Bima Regency, Indonesia, as hand sanitizers. The type of research is experimental research, with a completely randomized design with two factorials: concentration of medicinal plant extracts and the ratio of alcohol and triclosan. The medicinal plants used are cherry, meniran (Phyllanthus Urinaria), the burden of straw, ketepeng (Senna alata), white turmeric, and guava, taken from the leaves. The results showed that the test plant extracts (cherry, meniran, pandanus, ketepeng, white turmeric, and guava) all had inhibitory power based on the test concentration. The ability of the inhibition of bacteria in the test plant extracts had different diameters of inhibition, where the average concentration of each concentration that had the lowest diameter of inhibition could be seen in the plant extract. In contrast, in the plant extract treatment, the inhibition zone began to appear at a concentration of 20%. In other treatments with other test plant extracts, a zone of the inhibition began to form at a concentration of 10%. Meanwhile, the plant extract which has the largest relative inhibition zone is the white turmeric plant extract. Tests on each test, namely cherry, meniran, ketepeng, white turmeric, and guava, used a concentration of 10%, and the burden of straw used an extract concentration of 20%. The overall hand sanitizer shows characteristics in the treatment concentration A1 = 4% and the concentration of alcohol and triclosan B2 = 1 ml: 1.5 g.pH of the hand sanitizer for various plants was obtained in a relatively similar pH range, namely in the range of 6.06 - 6.82.

Publisher : Department of Mathematics and Science Education, Faculty of Teacher Training and Education, University of Mataram

The research aims to determine the influence of flash media on students' understanding of scientific literacy in stoichiometry. The research method used one group pretest-posttest design. The research was conducted in the tenth grade in one of the State Senior High schools in Gresik, East Java, Indonesia. The three meetings in action research were running well. However, there are obstacles where the device used is very limited, so teachers need to find the solution. Student activity during learning gets a percentage average of 87.67%. It means students were very active. Student learning outcomes show that 97% of students complete the standard minimum of completeness, 34 students complete, and one student does not complete. The Wilcoxon test shows a significantly average student learning outcomes, and the n-gain value for all students of 0.72 is relatively high. The results of the percentage of students' positive responses of 87% are classified as very good. In conclusion, learning by using flash media can be accepted by students and increase their understanding of scientific literacy on stoichiometry.

Publisher : Department of Mathematics and Science Education, Faculty of Teacher Training and Education, University of Mataram

The study aims to describe the effect of the inquiry learning model on student critical thinking skills and collaborative skills. The one-group pretest-posttest design was used in the study. The samples were 31 students in grade eight of junior high school in Surabaya, Indonesia. Learning performance data is obtained through observation methods, students' critical thinking skills data through writing test methods, and collaborative skills with observation methods. Learning implementation data is then analyzed with mode formulas. Critical thinking skill data is analyzed using the paired-sample t-test. Collaboration skill data is analyzed with the mode formula. Critical thinking skills indicators are providing simple explanations, building basic skills, concluding, providing advanced explanations, and organizing strategies and tactics. Collaborative skill indicators are working productively with a group of friends, being jointly responsible for getting work done, participating respectfully in discussions, debates, and disagreements, committing to putting group goals first, showing flexibility, and compromising. The study showed that tcount=12.961 and ttable=30. It means that a structured inquiry learning model can improve students' critical and collaborative thinking skills.

This study aimed to describe the implementation of learning, the improvement of students' critical thinking skills, and the student responses after applying the structured inquiry learning model to the sub-material of fluid pressure. This type of research used a pre-experimental design with one group pretest-posttest design. The research subjects used were students of the public junior high schools in Surabaya, Indonesia. This study used several instruments in the form of learning implementation observation sheets, test sheets, and questionnaire sheets which were then analyzed by quantitative description. The results showed that the implementation of learning obtained very good criteria with mode 4. Normality tests, paired t-tests, and N-Gain were used to analyze research data. The result of the standard test is significant. The value is 0.122, which means the data is normally distributed. Paired t-test produces a Sig value of 0.000 <0.05, which means a significant difference after being given treatment in a structured inquiry learning model. The improvement of students' critical thinking skills can also be seen from the N-Gain results on each critical thinking skill indicator with a score of 0.81 (high), 0.77 (high), 0.91 (high), 0.76 (high). and 0.84 (high). Students gave positive responses to the application of this learning model with an average score of 93.81%, and the criteria were very high. These results indicate that students' critical thinking skills can improve after the applied structured inquiry learning model.
