Abstract

Meatballs are one of the favorite processed foods. They are round and made from livestock meat with starch or cereals. The texture and chewiness of meatballs should be determined by the meat used as the main ingredient in the production process. Still, borax is usually added to reduce production costs, which, if consumed continuously, can interfere with health. Therefore, this study aims to identify the presence of borax in meatballs in Sekaran Village, Semarang City, with the natural indicator of hibiscus flowers. Hibiscus flowers were chosen because they contain anthocyanin extract that can be used as a qualitative indicator of the presence of borax compounds in a food sample. The test results showed that all five meatball samples were positive, as evidenced by the formation of a purple ring with a white base on the indicator paper. This indicates that the public still needs to be vigilant when consuming food, and related agencies still need to intervene to conduct periodic checks and withdraw various food products, especially those containing borax compounds.

Abstract

Collaboration and communication are essential 21st-century skills. Observations and interviews suggest that these are among students in science learning are still not fully developed. This study aims to analyze the differences in collaboration and communication skills between the experimental and control classes and examine the relationship between these two skills through implementation of the Self-Organized Learning Environment (SOLE) model, integrating thinking actively in a social context (TASC). The research employed a quantitative method with a quasi-experimental design. The study groups being a pretest–posttest control group involving two seventh-grade classes (VII G and VII H), selected through cluster random sampling. Research instruments included validation sheets, questionnaires, and observation rubrics. The data analysis techniques employed included the homogeneity test, the normality test, the independent sample t-test, and the correlation test. The findings revealed significant improvements in collaboration and communication skills in the experimental class compared to the control class (p < .05). Pearson correlation analysis further indicated a very strong positive relationship (r = .854; p < .05) between the two skills in the experimental class. These results suggest that integrating the SOLE-TASC is effective in enhancing students’ collaboration and communication skills in science learning compared to conventional instruction.
