This study assesses the influence of organizational culture, physical work environment, and non-physical work environment on employee performance at UD. Sumber Rejeki. Organizational culture is understood as the values, norms, and patterns of behavior agreed upon by members. The physical work environment refers to tangible conditions such as layout, lighting, and cleanliness. The non-physical work environment relates to the psychological climate and social relationships in the workplace. The research design is quantitative with a census or saturated sample technique. All 32 employees were respondents. The instrument was compiled using a Likert scale. The data were processed using SPSS 25. The analysis stages included validity, reliability, normality, multicollinearity, heteroscedasticity, multiple linear regression, t-test for partial effects, f-test for simultaneous effects, and the coefficient of determination R². The partial test results showed that organizational culture did not have a significant effect on employee performance. Conversely, the physical work environment and non-physical work environment had a positive and significant effect. The simultaneous test confirmed that the three variables together had a positive and significant effect on performance. These findings indicate that improvements in physical aspects such as room comfort, equipment, and safety standards, as well as strengthening non-physical aspects such as supervisor support, role clarity, and communication, are more directly related to performance improvement than existing cultural characteristics.

This study investigates the use of experimental statistical analysis as an instructional approach to enhance students’ understanding of variable relationships in science learning. Many students tend to memorize experimental results without comprehending the underlying relationships between variables, resulting in limited analytical reasoning and superficial understanding. To address this issue, the present study explores how integrating basic statistical tools-such as mean, correlation, and regression-into experimental activities can strengthen conceptual comprehension, analytical reasoning, and scientific literacy. Grounded in constructivist and inquiry-based learning frameworks, the research emphasizes active engagement, where students participate in data collection, analysis, and interpretation to draw evidence-based conclusions. The study employed a quasi-experimental design involving science students divided into experimental and control groups. Both groups conducted similar laboratory experiments, but only the experimental group received explicit instruction in statistical analysis. Data were collected through pre-tests and post-tests to measure changes in students’ understanding of variable relationships. The results indicated a 25% improvement in the experimental group’s comprehension and reasoning ability compared to the control group. Students who applied statistical analysis demonstrated greater proficiency in interpreting data, identifying causal patterns, and connecting theoretical knowledge to experimental findings. In contrast, students taught through traditional narrative-based instruction showed minimal gains and relied heavily on memorization. The findings highlight the effectiveness of integrating statistical reasoning in promoting critical thinking, problem-solving, and scientific reasoning skills.
