Abstract

This study aimed at identifying chemical and microorganism contamination in foods of street vendors around Institut Agama Islam (IAIN) Syekh Nurjati Cirebon. The samples are meatball, cilok, grilled fish cake, nuggets, rolade, sauce, crackers, and iced water drinks. The sample tests are formalin test, borax test, Rodhamine B test, Methanyl Yellow test, and Coliform Escherichia coli MPN test. The results showed that some food samples like meatball, cilok, grilled fish cake, nuggets,and rolade were positive of formalin borax contaminated. The iced water drinks are contaminated by Coliform E. coli. The other samples like sauce and crackers  were negative of Rhodamine B Methanyl Yellow contaminated. In conclusion, according to this study, the foods of street vendors at IAIN Cirebon are not yet safe to be consumed.

Abstract

This research aims to determine the relationship between interest in learning and learning independence with students' biology learning outcomes. This research uses a quantitative approach to analyze data. The research population was students of the MIPA MAN 2 Kuningan class for the 2021/2022 academic year with a sample of 98 students using a purposive sampling technique. Instruments for collecting data use questionnaires and documentation. This research data was analyzed using descriptive and inferential statistical techniques. The research results concluded that 1) the relationship between interest in learning and biology learning outcomes has a significant and positive relationship, with a correlation contribution in the weak category, namely 5.4%. 2) the relationship between learning independence and biology learning outcomes has a significant and positive relationship, with a correlation contribution in the weak category, namely 11.4%.

Abstract

This study integrates local wisdom as a basis for developing contextual chemistry education in the Ciayumajakuning region, Indonesia. Using the Model of Educational Reconstruction (MER) as its theoretical framework and an ethnographic approach to deeply explore cultural values, the research aims to identify potential local wisdom practices and map the scientific structure embedded within them. Through surveys, direct observations, interviews, and literature reviews, three local wisdom contexts—peuyeum ketan, jamasan keris, and the production of traditional Majalengka roof tiles—were identified and analyzed. The findings reveal that each context encompasses fundamental chemical concepts such as fermentation reactions, redox processes, thermochemistry, kinetics, and atomic and mineral structure. In-depth analysis uncovers a close interrelationship between cultural practices and chemical principles, thereby opening opportunities for the development of teaching materials and instructional models that are not only scientifically accurate but also culturally relevant. These results are expected to enhance students' interest in and understanding of chemistry through a meaningful contextual approach.
