Abstract

From the research results can be known the factors that affect the performance of the building. ICU Room Facilities, Jambi Provincial Hospital, the biggest is done by A21 on the first day that is equal to 91.771%. LUR level on the 2nd day, produced by A22 that is equal to 91,979%. While the level of LUR on the 3rd day generated by A9 of 91.146%. The predetermined variables are Education, Worker's Wage, Workers Health, Inter-Worker Relations, Managerial or Management, and Conformity of Use Simultaneous tools have no significant effect on the productivity of roof structure work. Partially or individually variables that have a significant influence on the energy level of work is the variable Work Experience and the variable of Conformity. Age / Age Comparison Variables have dominant influence on labor productivity level in the Improvement of Space Facility ICU RSUD Raden Mataher Jambi Province. Results of SPSS: 1)  Test Validity, Based on the results of the study, can be concluded in 18 valid questions if r arithmetic> r table. And Variable Variable P12 is a variable that is not vailid, because this variable is not vailid because of the clarity of important question intentions, so the respondents have a big difference of perception and in the end cause the question becomes vailid; 2) Test Reliability, got all variables Cronbach's Alpha for test Reliability questionnaire can meet Cronbach Alpha value between 0.7-0.9, indicating the research questionnaire has a high Reliability value;3) Normality test, In the normality test, the researcher uses Shapiro-Wilk because the tested data is smaller than 50, whereas if more than 50, using the Kolmogorov-Smirnova part. Under the table of 4.27 above, the Index has the star number of Shapiro-Wilk test from 0.05 indicates normal distributed dataKeyword: Productivity

Abstract

Scientific literacy and critical thinking skills are essential competencies for students in responding to the demands of twenty-first-century education. However, various assessments indicate that Indonesian students’ scientific literacy remains relatively low, underscoring the need for instructional models that actively engage learners in inquiry-based knowledge construction. This study aimed to examine the effect of the Inquiry Learning model on the scientific literacy and critical thinking skills of fifth-grade students at SDN Sukadanau 04. A quantitative approach with a quasi-experimental non-equivalent control group design was employed. The sample consisted of 60 students divided into experimental and control groups. Data were collected through observation, interviews, tests, and documentation, and were analyzed using normality tests, homogeneity tests, independent sample t-tests, and regression analysis. The findings revealed that the Inquiry Learning model had a positive and significant effect on students’ scientific literacy and critical thinking skills. The independent sample t-test showed a significance value of 0.000 (p < 0.05), while regression analysis produced an R² value of 0.707, indicating that the model substantially explained improvements in the measured competencies. These findings demonstrate that Inquiry Learning is more effective than conventional instruction in enhancing scientific literacy and critical thinking skills among elementary school students. The study contributes to science education by providing empirical evidence on the effectiveness of Inquiry Learning as an alternative instructional model for fostering twenty-first-century competencies in elementary education.
