This study aims to test the feasibility of multiple representation-based interactive Android applications on atomic structure material as an independent learning resource for students at Karitas Tomohon Catholic High School. The research method used is Research and Development (R&D) with the ADDIE development model (Analysis, Design, Development, Implementation, Evaluation). The results showed that this application was able to facilitate learning by integrating three levels of chemical representation (macroscopic, microscopic, and symbolic). The research subjects included chemistry teachers, grade X students, especially grade X-A, as well as two media experts and two material experts. Validation by media experts showed a feasibility level of 87%, while material expert validation reached 96%. The chemistry teacher's response gave a feasibility level of 100%, while the student's response reached 88%, both of which were included in the very feasible category. This application is expected to be an innovation in chemistry learning, especially as an interesting and useful independent learning media.

Food safety is a critical aspect in protecting the public from hazardous contamination. Wet noodles have a relatively short shelf life, making them susceptible to misuse through the addition of formaldehyde as a preservative. This study aimed to qualitatively identify the presence of formaldehyde and to provide a preliminary estimation of its concentration in wet noodles sold at Tondano Market. Qualitative analysis was conducted using potassium permanganate (KMnO₄), while quantitative analysis was performed indicatively using UV–Vis spectrophotometry with chromotropic acid reagent at a wavelength of 520 nm. The results indicated that all samples were positive for formaldehyde. The detected concentrations were 54.01 mg/kg, 35.82 mg/kg, and 26.43 mg/kg, respectively. The presence of formaldehyde in all samples indicates a violation of food safety regulations and poses potential health risks to consumers. These findings highlight the need for stricter monitoring of wet noodle distribution in traditional markets.

Chemistry learning requires the integration of macroscopic, submicroscopic, and symbolic representations. However, limited availability of practicum tools in senior high schools often hinders students’ comprehensive understanding of chemical concepts, particularly in electrolyte and nonelectrolyte solutions. This study aimed to develop and implement CHEMLIT, a sensor-based chemistry practicum tool designed to support learning on solution electrical conductivity. The study employed a Research and Development (R&D) approach using the ADDIE model, consisting of analysis, design, development, implementation, and evaluation stages. Needs analysis was conducted through classroom observations and teacher interviews, followed by prototype design, assembly, calibration, and functional testing to ensure stability and safety. The implementation involved two senior high schools in the Minahasa region, with chemistry teachers serving as reviewers and students as trial users. Feasibility was evaluated by media experts, material experts, teachers, and students using five-point Likert-scale questionnaires, and the data were analyzed by converting scores into percentage-based feasibility criteria. Product feasibility was evaluated through validation by media experts, subject matter experts, chemistry teachers, and students using questionnaire instruments. The validation results indicated a very high level of feasibility, with scores of 91.7% from media experts, 96% from material experts, 92% from teachers, and student responses exceeding 93.99%, categorized as very good. These findings indicate that CHEMLIT meets technical, visual, and content feasibility standards and can serve as an alternative practicum tool for teaching electrolyte and non-electrolyte solutions, especially in schools with limited laboratory facilities. Its novelty lies in a portable sensor-based design that integrates quantitative conductivity measurement into conventional testing without complex digital systems.
