Publisher : Universitas Muhammadiyah Prof. Dr. Hamka

Background: The implementation of flipped learning could be one of the solutions offered so that practicum that was limit by time could be carried out. This study aimed to determine the effect of implementing the flipped learning model on student understanding of the squash method material in microtechnique courses. Methods: This quasi study used a non-equivalent control group design. In the treatment group the flipped learning model was applied and an analysis of its effect on student understanding was carried out. The research data were obtained through the pretest and posttest. The pretest is used to evaluate the ability to remembering and understanding, while the posttest evaluates the ability to analyze, evaluate and create. The pretest and posttest value data were used to calculate the N-gain value, then the Mann-Whitney U test was performed to determine the difference between the two. Results: The increase in the mean value in the treatment class was higher than in the control class. The treatment class was 5.2, while the control class was 0.82. The percentage of students who showed a high and moderate N-gain score in the treatment class was 54.05%, while the control class was 40%. There was no difference between the N-gain value in the treatment and control classes. The flipped learning model's implementation did not affect student understanding but had been able to increase student understanding of the squash method material. Conclusions: The flipped learning model could be applied as a solution to practical problems constrained by time constraints.

Background: Diabetes Mellitus is a chronic metabolic disorder caused by insulin resistance. Noni juice has the potential as herbal medicine which believed to reduce blood glucose levels. This study aims to determine the effect of noni juice on blood sugar levels on diabetic patients. Methods: This study used 16 respondents. They divided two groups, a control group and a treatment group. Each group consists of 8 respondents. The intervention group received 150 ml of noni juice which was given once a day for ten days. Glucose testing was carried out by the glucose-check method. The blood was taken from the respondent's fingertips capillary. The blood glucose levels between the control group and the intervention group were analyzed using independent t-test. Results: The average blood glucose level in the intervention group was 199.88 mg/dl, while the control group was 326.25 mg/dl. The test results of the mean blood glucose levels between the control group and the intervention group had a significant difference with a value of p = 0.003 (p ≤ 0.05). This indicates a significant effect between blood glucose levels in the control group and the intervention group. Conclusion: Noni can reduce blood glucose levels because it contains flavonoid. It has a hypoglycemic effect. Health workers can suggest consuming noni juice to decrease blood glucose in diabetic patients.

Publisher : Universitas Muhammadiyah Prof. Dr. Hamka

Background: A misconception is a form of error in scientific knowledge that is believed to be accurate. As a result, someone who has a misconception of something will reject scientific truth and will hinder the assimilation of new knowledge. The purpose of this study was to identify misconceptions that occur in students regarding the topic of blood classification. Methods: The survey method research was conducted on 97 students scattered in Malang and Tulungagung, Indonesia. The data analysis technique uses coding for categorization into four categories: conceptual understanding, partial understanding, misconception, and not understanding the concept. Results: The results showed that misconceptions occurred in all sub-topics of blood classification. Misconceptions were found in the concept of blood plasma (2.1%), white blood cells (6.2%), thrombocytes (17.5%), and blood classification system (8.2%). Misconceptions occur due to several misunderstandings of students such as red blood cells that play a role in transporting nutrients, haemoglobin only binds oxygen, and difficulty distinguishing between antigens and antibodies in determining blood groups, blood donation, and the impact arising from donations. Conclusion: The existence of misconceptions causes students' mastery of blood classification material to be hampered.
