Abstract

ntroduction: Pituitary macroadenomas are benign neoplasms of the pituitary gland that often cause significant mass effects, such as compression of the optic chiasm and cavernous sinus, as well as hormonal disturbances. Studies on the demographic characteristics, chief complaints, and imaging features of pituitary macroadenomas in Indonesia remain limited. This study aims to provide a comprehensive overview of patients with pituitary macroadenomas at Saiful Anwar General Hospital. Objective: This study aims to analyze the demographic distribution, clinical complaints, and MRI imaging characteristics of patients with pituitary macroadenomas. Methods: This retrospective descriptive study involved 23 patients who underwent brain MRI at Saiful Anwar General Hospital between January 2020 and December 2024. Demographic data, chief complaints, and MRI imaging findings were analyzed descriptively. Variables evaluated included age, gender, chief complaints, tumor consistency, and signal intensity on T1- and T2-weighted sequences. Results: Among the 23 patients, 82.6% were female, with a mean age of 46.95 years. The most frequently reported complaint was blurred vision (43.5%), caused by optic chiasm compression. Most tumors were solid (69.6%), with hyperintensity dominance on T2-weighted sequences (78.3%). Suprasellar extension was observed in most patients, involving the optic chiasm and cavernous sinus. Conclusion: Pituitary macroadenomas are more commonly found in middle-aged females, with visual disturbances being the dominant complaint. MRI revealed solid consistency with signal heterogeneity, emphasizing the importance of radiological evaluation for early diagnosis and therapeutic planning. A multidisciplinary approach is essential to improve patient quality of life.

Abstract

The aim of the research is to find out what students’ interests and learning outcomes are who use the Discovery Learning model is higher than interest and learning outcomes of students who use conventional learning models. This type of quasi-experimental research with a pretest posttest nonequivalent control design group design. This research was carried out at MTs DDI Malunda for the 2023/2024 academic year. Where class VIII B is the experimental class and class VIII A is the control class with a saturated sampling technique. Data collection using questionnaires, test and observation sheets on the implementation of learning by teachers and students. Data analysis techniques use descriptive and inferential analysis. Descriptive analysis the average score of the experimental class posttest questionnaire (89.96), the average score of the posttest questionnaire control class (75.69). For the average test score for the experimental class (86.53), while the score control class posttest average (61.23). Results show interest and learning outcomes mathematics students are taught using the Discovery Learning model more high compared to the interest and mathematics learning outcomes of the students being taught using conventional learning models. To test the hypothesis used are the T-Test and ManovaTest with sig values. Students’ interest in learning mathematics (0.000<0.05) and obtained a sigvalue. Student learning out comes (0.000<0.05) means H1 accepted. The conclusion is that students’ interests and learning outcomes in mathematics are using the Discovery Learning model is higher than interest and mathematics learning out comes of students who use the learning model conventional.

Abstract

This research is a Research and Development study using the ADDIE model (Analysis, Design, Development, Implementation, Evaluation) with seventh-grade junior high school students as the subjects. The aim is to produce a learning media in the form of an Electronic Student Worksheet (E-LKPD) using the Liveworksheet main platform on the topic of algebraic forms. In the Analysis phase, information was gathered from teachers and students, revealing that the school only utilized printed books or worksheets and had not yet implemented technology-based learning media. In the Design phase, the plan for the E-LKPD product on the topic of algebraic forms was created, utilizing the Liveworksheet platform as the main medium, and Microsoft Word and Canva as supporting media. Development involved both product development and validation by three validators, resulting in a valid E-LKPD. The assessment of the feasibility of the learning media product by content experts averaged 4.31, categorized as Very Good, while media experts gave an average of 4.33, also categorized as Very Good. During the Implementation phase, a limited trial was conducted with seventh-grade junior high school students. Practicality was assessed with 83.73% of students rating it as Very Good, and 96% of teachers also rating it as Very Good. The Evaluation phase involved assessing each stage to ensure the development of a high-quality and accurate product.

Abstract

: This study aims to identify the influence of digital literacy, learning motivation, and creative thinking on students' mathematics learning achievement. The sample of this study was 50 students of class VIII of SMP Negeri 3 Wamena. Data collection includes digital literacy questionnaires, learning motivation, and creative thinking written test questions, as well as documentation of mathematics scores. The results of the regression analysis showed a positive relationship between the independent variables and the dependent variables with a Multiple R-value of 0.3065, still only 9.39% of the variation in mathematics learning achievement can be explained by the three independent variables (R Square = 0.0939), the smaller the Adjusted R Square of 0.0348 indicates that this model has low predictive power. X1 (digital literacy) and X2 (learning motivation) are not significant to mathematics learning achievement with p-values ​​of 0.315 and 0.430 respectively, indicating that both do not affect mathematics learning achievement, on the other hand, X3 (creative thinking) with a p-value of 0.055 approaching the significance limit which means that the possibility of its influence is more significant. This study suggests the need for a more in-depth approach to other factors that contribute to students' mathematics learning achievement.

Abstract

At this time, computational thinking ability is very important because it can help humans in achieving success in the world of work and society is getting bigger. This preliminary study aims to identify and explore the computational thinking skills of junior high school students and the factors that influence them. The research method used was mixed methods by giving 3 description questions on linear function material that can measure computational thinking ability to 35 class IX students in one of the junior high schools in Sukabumi. The results showed that the highest score achieved by students was 91.67 while the lowest score was 16.67. The average score was 58.33 with 20 students above average and 15 students below average. The median test score was 58.33 with the modes being 44.44 and 61.11. After analyzing each student's answer, it was found that the computational thinking ability of junior high school students was at a low level. The test results stated that students were only capable of the problem decomposition and algorithm stages, not yet to the stages of pattern recognition and abstraction. Students tend to perform calculations directly after breaking down the problem into smaller parts and writing down sequential steps to solve the problem. This shows that mathematics learning in schools today is still lacking in directing students to computational thinking skills.
