Abstract

Scientific literacy and creativity are essential present century competencies that students must develop. The implementation of the Project-Based Learning (PjBL) model integrated with STEM is applied as a solution to foster students' scientific literacy and creativity. This research aims to explore the implementation of the STEM integrated PjBL model in optimizing scientific literacy and student creativity in the environmental pollution learning process.. The research employed a quantitative descriptive approach using a quasi-experimental method. The design used was a non-equivalent control group design, with samples selected through cluster random sampling. The instruments included pretest and postest questions to assess scientific literacy, and observation sheets to measure students’ creativity. The collected data were first tested for homogeneity and normality. Further analysis was conducted using the Independent Samples t-Test and N-Gain test. The t-test results showed a significance value of 0.000, indicating a significant difference in the mean scores between the experimental and control classes. The N-Gain test revealed that the scientific literacy improvement in the experimental class reached 0.67 (moderate category), while the control class reached 0.40 (moderate category). Meanwhile, creativity in the experimental class achieved an N-Gain score of 0.79 (high category), and the control class scored 0.58 (moderate category). Therefore, it can be summarized that the PjBL-STEM model effectively enhances the scientific literacy and creativity of seventh-grade students at SMP Negeri 33 Semarang.

Abstract

Science learning includes the study of concepts as well as practical activities. Practical science learning can run effectively when supported by adequate laboratory facilities and infrastructure. This study aims to develop a low-cost and environmentally friendly DNA isolation kit as an alternative medium for molecular biology practicum that is more affordable and easier to implement in educational laboratories. The kit development utilizes simple materials and equipment that are easily obtained from the surrounding environment, such as enzyme-based liquid detergent, table salt, natural enzyme extracts (pineapple, ginger, papaya leaves, and papain), and ethanol. The research method employed an experimental approach through stages of kit formula design, optimization of lysis buffer composition, and effectiveness testing on various plant and animal tissue samples, namely strawberry, broccoli, chicken liver, and chicken meat. The success parameters were observed through the visualization of DNA threads resulting from precipitation and the measurement of DNA quantity and purity using a spectrophotometer. The results indicate that all kit formulas were able to extract DNA with varying levels of success, where strawberry and chicken liver samples showed the clearest DNA thread visualization and the best color appearance. These findings demonstrate that a locally based, low-cost, and eco-friendly DNA isolation kit is effective as an alternative to commercial kits and has strong potential to support science learning, particularly in genetics and biotechnology, through more practical and economical laboratory activities.
