One aspect of development that must be well-stimulated in early childhood is cognitive development. Cognitive development can be stimulated through children’s basic mathematical skills. These skills can be enhanced through the application of Kosurasi media. This study aims to determine the effect of applying Kosurasi media in improving basic mathematical skills in children aged 5-6 years at TK Dharma Wanita Bandung Wonosegoro. This study used a quantitative method with a one-group pretest-posttest research design. The population and sample consisted of 30 children aged 5-6 years at TK Dharma Wanita Bandung. Data collection was conducted through observation, interviews, and documentation. The collected data were analyzed using normality tests, homogeneity tests, paired sample t-test hypothesis testing, and finally, N-gain score tests with the help of the SPSS V.26 data processing application. The average pretest score was 76.10, while the average posttest score was 115.33. A paired sample t-test hypothesis test yielded a significance result of 0.000 < 0.05, indicating that H0 was rejected and Ha was accepted. This means there was a significant difference in the children’s basic mathematical skills before and after the intervention. Furthermore, the N-gain test produced a score of 57.76%, suggesting that the application of Kosurasi media has a moderately effective impact on improving the basic mathematical skills of children aged 5-6 years.
 

The Consumer Protection Law (UU 22/2020) has provided a legal basis for consumer protection in the banking industry.  The implementation of this law is important in the Islamic banking industry due to its consistency with sharia values which place justice and balance as the main principles.  The purpose of this study is to analyze the implementation of the Consumer Protection Act in the Islamic banking industry and evaluate the effectiveness of its implementation.  This research uses a qualitative approach with a literature study.  Data was collected through analysis of book literature and analysis of documents related to the implementation of the Consumer Protection Act.  The results of the study show how actual implementation of the Consumer Protection Law is in its operational procedures.  However, there are several challenges in implementation, such as the lack of awareness and understanding of customers about their rights, as well as a lack of adequate human resources and information technology to meet the requirements of the law.  This study recommends that Islamic banks increase consumer empowerment campaigns and invest in adequate human resources and information technology to increase the effectiveness of the implementation of the Consumer Protection Act.  This is expected to increase customer confidence in the sharia banking industry and support sustainable industry growth.
