The instrument used in the form of a questionnaire compiled by the researcher. The data was analyzed first by testing the data analysis requirements, namely normality test, regression linearity test and multicollinearity test. After the test data requirements were met, a differential analysis was carried out for testing the research hypothesis using correlation analysis and multiple regression techniques. From the results of the study it was found that: (1) there was a positive and significant influence of organizational culture and interpersonal communication together on improving teacher performance; (2) there was a positive and significant influence of organizational culture on improving teacher performance; (3) there was a positive and significant effect of interpersonal communication on teacher performance.

Abstract

The low level of knowledge about the appropriate use of antibiotics causes the practice of irrational antibiotic use to increase. The aim of this community service is to provide education about understanding antibiotics and how to use them appropriately and rationally. The community service method is by providing education through group discussions, workshops and seminars to health workers, posyandu cadre mothers and the community around Ratujaya Village, Depok. The level of knowledge about antibiotic use was measured using a questionnaire, pretest and posttest. The results achieved by this community service after providing education on understanding antibiotics and their use to the community show that people who have good and sufficient knowledge about antibiotics are 88.57%, meaning that more people understand about antibiotics than those who don't. It can be concluded that the education on the use of antibiotics provided to the public can sufficiently increase public knowledge regarding antibiotics.

Abstract

This study aimed to describe the dimensions of mathematics anxiety based on gender during the learning of Linear Algebra and Matrices. Mathematics anxiety is a psychological factor that influences students' thinking ability, self-confidence, and academic performance when dealing with mathematical problems. This study employed a quantitative descriptive approach involving 40 fourth-semester students at Universitas Indraprasta PGRI during the 2025/2026 academic year. Data were collected using a questionnaire consisting of 23 Likert-scale items measuring three dimensions of mathematics anxiety: somatic, cognitive, and attitudinal. The data were analyzed using descriptive statistics and classified according to the dimensions and measurement criteria of mathematics anxiety. The findings indicated that students' mathematics anxiety percentages ranged from 54.66% to 63.58%, suggesting that their mathematics anxiety levels were within the moderate to high categories. In the somatic dimension, the mathematics anxiety percentage was 55.00% for female students and 54.66% for male students. In the cognitive dimension, both male and female students exhibited the highest anxiety levels compared with the other two dimensions, with percentages of 62.91% and 63.58%, respectively. In contrast, in the attitudinal dimension, male students demonstrated a slightly higher percentage (56.69%) than female students (55.50%). Overall, students' mathematics anxiety was predominantly influenced by the cognitive and attitudinal dimensions. Therefore, efforts to reduce mathematics anxiety should focus on instructional strategies that enhance students' self-confidence, provide opportunities for gradual learning, foster a supportive and low-pressure classroom environment, and offer constructive support and positive feedback to help students overcome anxiety when solving mathematical problems.
