The lack of integration between science and local wisdom in science education remains a challenge in developing students' critical thinking skills and cultural literacy. This study aims to analyze the effect of STEM-based science learning integrated with ethnoscience on critical thinking skills and cultural literacy of elementary school students. This research is a quantitative study with a quasi-experimental method using a nonequivalent control group design. Samples were selected purposively and consisted of experimental and control groups. The instruments used include a critical thinking skills test and a cultural literacy questionnaire. Data analysis was performed using a paired sample t-test. The results showed a significant difference in posttest scores between the experimental and control groups, with a significance value of 0.000 <0.005. The average difference was 19.78 points for critical thinking skills (81.14 - 61.36) and 16.86 points for cultural literacy (82.50 - 65.64). This finding suggests that integrating STEM-based science learning with ethnoscience can significantly enhance students' critical thinking skills and cultural literacy. The novelty of this study lies in the learning approach that combines the STEM framework with local ethnoscience values, providing an innovative alternative for shaping students who think reflectively while developing cultural awareness from an early age.

Nowadays, advances in information and communication technology have had a major impact on various sectors of life, including in the field of trade and e-commerce. However, as it happens in the scope of social media, TikTok Shop is also dealing with challenges and changes. One of the issues that is sticking out and is currently hot is the permanent closure of the TikTok Shop feature that has occurred in Indonesia. This research will carry out several processes starting with data collection, then data labeling, data preprocessing, data sharing, weighting training data, using the Naive Bayes method, and ending with testing. In this study, the results of the implementation that has been made or built are discussed. The method used is the Naive Bayes Classifier Method to classify training data as much as 800 data, which is 80% of the total data. Then, testing is carried out using 200 testing data, which is 20% of the total data. The evaluation results show an accuracy value of 73%. In addition to the accuracy value, this research also recorded the precision, recall, and F1 score values. The classification that appears most often and contributes the highest in these values is the Positive classification as much as 420 data or 42% of the total data used..
 
 

The use of information technology in the world of education looks better. With the ease of getting this information, cases of parents who do not know the status of their children's education are increasingly rare. The use of technology in the world of education in teaching and learning activities cannot be done by one party alone. It takes the involvement of all, especially teachers and students. If you look at the age of the teachers, of course, not a few of them can be considered old. This is what makes not a few of the teachers still rigid with technology. But it's a different story with today's school students. The year of birth of school students is currently in the generation Z category, where technology is their lifestyle. The method of transferring knowledge from teachers to students must be changed so that knowledge can be well absorbed by students. This community service aims to provide training on the use of Google Classroom as one of the school's e-learning at SMP N 2 Kasihan.
