Pangan Jajanan Anak Sekolah (PJAS) is one of the foods consumed by people in Indonesia, especially by children and adolescents. This food is very vulnerable to contamination by microorganisms that can damage and can be toxic to the human body when consumed. Microbes can contaminate food through water, dust, air, soil, processing equipment (during the production or preparation process) as well as secretions from the intestines of humans and animals. The method used is literature review by collecting, evaluating, and synthesizing existing studies in the scientific literature. In this case using a search engine such as google scholar. The years obtained from articles from 2018 to 2024 are relevant to the topic of this research. The topic used is the identification of Escherichia coli bacteria in meatball meat samples as school snack food (PJAS), this method is used to gain an in-depth understanding of Escherichia coli bacteria in meatball meat samples as school snacks. According to the World Health Organization (WHO), an estimated 600 million people globally (nearly 1 in 10 people) fall ill including diarrhea, kidney and liver failure, brain and nerve disorders, reactive arthritis and cancer from food-borne diseases, with 420,000 deaths reported in 2010. Food-borne illnesses arise from the consumption of contaminated food, which can be.
 

The diversity of macroalgae species in Indonesia's coastal ecosystems is important to understand and protect. Indonesia has a very long coastline and a variety of ecological conditions, from tropical to subtropical areas. This area provides a habitat that supports the growth of various macroalgae species. The method used is a qualitative research method analyzing the diversity of macroalgae species in Indonesian coastal ecosystems and the level of understanding of high school/MA level plant-like protists. Based on the research results, it can be concluded that the level of understanding of SMA/MA students about plant-like protists is still low. Students have difficulty distinguishing between protists and true plants

This study aims to improve students' mathematics learning outcomes through the implementation of cooperative learning model using the Think Pair Share (TPS) technique. The subjects of the study were the students of class VII-A at SMPN 3 Surabaya. This Classroom Action Research (CAR) was conducted in two cycles, each consisting of planning, implementation, observation, and reflection stages. Data were collected through tests, namely formative tests and post-tests. The results showed a significant improvement in students' mathematics learning outcomes after the application of the Think Pair Share technique. In the first cycle, the average student scores increased significantly compared to before the intervention, with even greater improvements observed in the second cycle. Besides improving learning outcomes, the application of the Think Pair Share technique also had a positive impact on student participation and interaction during the learning process. Students became more active in discussions and helped each other understand the lesson material. Therefore, the Think Pair Share technique has proven effective in enhancing the mathematics learning outcomes of students in class VII-A at SMPN 3 Surabaya.

Mathematics plays a crucial role in developing students' problem-solving abilities and independence. Educators need to consider the varying characteristics of students when it comes to solving problems, one of which is their adversity quotient (AQ) level. The adversity quotient relates to a student's ability to handle complex problems or to overcome challenging situations. This research aims to analyze the mathematical problem-solving abilities of Class X students in the context of Systems of Linear Equations in Two Variables (SPLDV) based on their Adversity Quotient (AQ). This qualitative, descriptive study involved selecting research subjects using an AQ questionnaire and was conducted in Class X. Data collection methods included testing, interviews, and documentation. Data analysis techniques included data reduction, data presentation, and conclusion drawing. The results indicate that subjects with the Climber type can understand problems, develop problem-solving plans, solve problems with accurate and appropriate steps, and use available information to re-check their answers. Subjects with the Camper type can understand problems, develop problem-solving plans, solve problems with accurate and appropriate steps, but often cannot use available information to re-check their answers. Subjects with the Quitter type can understand the problem and formulate a plan but struggle to solve the problem accurately and appropriately, and tend not to use available information to re-check their answers.
