Abstract

Background: Non-Alcoholic Fatty Liver Disease (NAFLD) is one of the most common chronic liver diseases and has become a health burden throughout the world over the last two decades. Hypertension, dyslipidemia, obesity, and insulin resistance are considered risk factors for PGK that overlap with the metabolic comorbidity of NAFLD. Several studies reported that the prevalence and risk of PGK events increased significantly in NAFLD patients compared with patients without NAFLD. Aim: To determine the relationship between controlled attenuation parameter scores, transient elastography, and FIB-4 scores with eGFR values in NAFLD patients. Methods: This was an analytical study with a retrospective approach and used a cross-sectional design. The subjects were taken using consecutive sampling technique. Data collection on CAP scores, TE scores, FIB-4 scores, and eGFR was carried out by looking at the patients' medical records. In this study, the Pearson correlation statistical test was used. Result: Correlation test results between CAP scores and eGFR showed a significant positive correlation (r=0.296; p=0.031), between TE scores and eGFR showed a non-significant positive correlation (r=-0.093; p=0.509), and FIB-4 score with eGFR showed a significant negative correlation (r=-0.281; p=0.042). Conclusion: There is a significant positive correlation between the CAP score and eLFG, a non-significant positive correlation between the TE score and eGFR, and a significant negative correlation between the FIB-4 score and eGFR. Keywords: CAP score, TE score, FIB-4 score, eGFR

Abstract

Technology that continues to develop requires teachers to continue to innovate in presenting quality learning media. Mobile learning is a medium that can be used in learning because of the ease in the process of using it anywhere and anytime. On the other hand, critical thinking is a very important ability in mathematics. Through critical thinking skills, students are required to be able to generate thoughts and choose the right steps to solve a problem. However, the results of the field study show that students' critical thinking skills in material on compositional and inverse functions are still very low. This study aims to develop mobile learning named KORS to train students' critical thinking skills in the matter of compositional and inverse functions. This type of research is development research with the ADDIE model. The subjects of this study were practitioners and six high school students. In collecting data, assessment instruments were used by media experts and material experts, as well as student and teacher response questionnaires. The results of this study obtained KORS mobile learning media that were feasible to use with a percentage of 79% from media experts and 78.67% from material experts. The practicality of the media from the teacher's assessment obtained a percentage of 83.33% and based on the results of small-scale trials obtained a student response questionnaire percentage of 82.67%.

Abstract

Using manipulative media can help children who are having trouble learning mathematics. In addition to simplifying the learning process, this manipulative media helps pupils develop their capacity for original thought. Creative thinking abilities are crucial because it inspire students to try different approaches to addressing problems, promotes creativity, and raises their level of involvement in class activities. Despite the significance of creative thinking abilities, prior studies have shown that Indonesian students still need to improve their levels of these capabilities, particularly regarding integer operations. Thus, to fill this gap, this research developed Media Tangkas Operasi Bilangan Bulat (METABUL). This media used the ADDIE paradigm in research and development (R&D) to stimulate students' capacity for creative thinking. Interview guidelines, learning media validation questionnaires, and teacher and student response questionnaires are the data collection instruments used in this research. The research participants were six class VII junior high school students in Malang City with three validators (one practitioner and two experts). Research findings show that developing METABUL manipulative media has a high level of validity of 93.17% and a good response from teachers at 86% and students at 87.41%.
