The increasing demand for Computational Thinking (CT) and Environmental Awareness (EA) in elementary science education highlights the need for innovative and culturally relevant learning approaches. However, traditional science teaching methods often emphasize rote memorization rather than problem-solving and ecological responsibility, leading to a lack of deeper conceptual understanding among students. This study investigates the influence of Unplugged Coding Learning integrated with Tri Hita Karana (THK) spiritual values on the development of CT and EA in elementary school students. This research employs a quasi-experimental design with a pretest-posttest control group approach. Data were collected using multiple-choice assessments for CT and EA and were analyzed using Multivariate Analysis of Variance (MANOVA) to determine the effectiveness of the intervention. The results indicate that students who participated in Unplugged Coding Learning with THK values demonstrated significantly higher gains in CT skills (logical reasoning, problem-solving, and pattern recognition) and EA (understanding sustainability and conservation principles) compared to the control group. The Palemahan aspect of THK, which emphasizes harmony with nature, contributed to students’ increased awareness of environmental issues. These findings suggest that integrating local wisdom into STEM education enhances both cognitive and ethical development. The study implies that culturally embedded educational approaches can bridge computational problem-solving skills with environmental consciousness, fostering a more holistic learning experience. Future research should explore long-term impacts and adaptability of this model across different educational settings.

The problem found in fourth grade is that the learning process tends to only use the lecture method so that students are not motivated to learn because it tends to be boring. In addition, the use of learning media is not optimal. This development research has objectives, namely to: (1) describe the design of PBL-based interactive learning video media, (2) find out the acceptability of PBL-based interactive learning video media, (3) find out the effectiveness of the application of PBL-based interactive learning video media used to increase IPAS learning motivation of grade IV elementary school students. This development research uses the ADDIE model, there are five stages, namely: (1) analysis, (2) design, (3) development, (4) implementation, and (5) evaluation. Data collection method with document study and questionnaire. The instrument used to collect data is a questionnaire guideline. The effectiveness of the model was tested through an experiment involving control and experimental groups, where pre-tests and post-tests were used to measure differences in student learning motivation before and after the application of learning media. The results showed that: (1) this study has succeeded in producing PBL-based interactive learning video media that ensures a more interactive and engaging learning experience, particularly suited for fostering problem-solving skills in science education of grade IV elementary school students. (2) media acceptability validation index of 0.944 with very high predicate / qualification; (3) the significance value (2-tailed) in the correlated t-test shows a number of <0.001, smaller than 0.05 (significance level of 5%). In conclusion PBL-based interactive learning video media is effectively used to increase IPAS learning motivation of grade IV elementary school students.
