This research aims to identify and synthesize previous research related to optimizing Problem-Based Learning (PBL) in improving students' critical thinking skills in mathematics learning through a systematic literature review. Data was collected from relevant scientific articles published in the last 10 years using certain keywords through databases such as Google Scholar, Scopus, and Web of Science. The results of the literature review show that the application of PBL consistently plays a role in improving students' critical thinking abilities, especially when supported by strategies such as the use of relevant contextual problems, structured feedback, and directed teacher guidance. These findings confirm the constructivist theory which states that meaningful learning occurs when students are actively involved in authentic problem solving. However, there are variations in results across educational levels and countries, indicating the importance of contextual adaptation in the implementation of PBL. In addition, the lack of comprehensive practical guidance and long-term evaluation instruments is a major obstacle. The conclusions of this research emphasize the need to develop clearer PBL implementation guidelines and more accurate evaluation instruments to measure its impact on students' critical thinking abilities, as well as the potential of PBL in improving the quality of mathematics learning that encourages critical thinking skills as an important competency in 21st century education.

The growth of e-commerce in Indonesia has led to the emergence of various online shopping platforms, with Shopee being one of the most popular in Semarang City. User reviews on the Shopee application serve as a valuable data source for analyzing customer satisfaction levels; however, the large volume of data requires a systematic and accurate analytical approach. This study aims to analyze user review sentiments of the Shopee application using three machine learning algorithms: Random Forest, Naïve Bayes, and Support Vector Machine (SVM), as well as comparing the accuracy of these three algorithms. This research utilized 1000 reviews collected through web scraping from the Play Store, which were categorized into three classifications: positive, neutral, and negative sentiments. The analysis process encompassed pre-processing stages, feature extraction using TF-IDF, and classification using Random Forest, Naïve Bayes, and Support Vector Machine algorithms. The results demonstrated that the Random Forest algorithm achieved the highest accuracy at 96.19%, followed by Support Vector Machine with 95.71% accuracy, and Naïve Bayes with 84.76% accuracy. This research highlights the effectiveness of Random Forest and SVM in classifying user review sentiments towards the Shopee application.

Degree certificate legalization system with encryption security feature using Advanced Encryption Standard (AES) in Semarang University has a purpose to support academic to do online document legalization through a system. The main problem which occurs in academic administration is a long document legalization process that causes an ineffective and inefficient legalization process. To solve the problem, a system that can encrypt a document for better security is required. This system is built with the Advanced Encryption Standard algorithm with a 128-bit sized key to encrypt confidential information inside the document. During the encryption process, this algorithm operates using 4x4 bit array blocks and passing many encryption processes for at least 10 (ten) times. The application is analyzed with object-oriented analysis and modeled with Unified Modeling Language.  The result of this research is a system which can secure document with AES algorithm with a 256-bit sized key. The security element in this algorithm will make easier to identify the owner of the document. The secured document is easily accessible through PHP-based web or available QR code. When decrypting the document, the application will activate the camera function and decrypt the information document.
