This study explores the role of sentiment analysis as a predictive tool for understanding and forecasting product launch success in the digital market. Sentiment analysis involves the classification of consumer sentiment expressed on social media platforms such as Twitter and Instagram, and it can significantly impact businesses by predicting consumer behavior and product performance. The research highlights the relationship between social media sentiment and product success, demonstrating that positive sentiment is strongly correlated with higher sales and consumer engagement, while negative sentiment can lead to declines. Machine learning models, including Support Vector Machines (SVM) and Random Forest, were employed to classify sentiment from large volumes of social media data and correlate it with product performance indicators such as sales volume and consumer interaction. The study found that sentiment analysis models were highly effective in predicting product success, with positive sentiment generally driving product profitability and negative sentiment posing a potential threat to brand reputation. Moreover, the analysis showed that social media sentiment provides real-time insights into consumer perceptions, enabling businesses to quickly adjust marketing strategies and product development plans. These findings underscore the importance of integrating sentiment analysis into product launch evaluations and strategic decision-making. Future research should explore the integration of sentiment analysis with other predictive market models and investigate the effects of fake reviews and post-purchase consumer behaviors on product success.

This article examines how Christian religious education curriculum can be a means to develop students' faith. This study uses a phenomenological approach to explore students' and teachers' experiences in the learning process.

This article recommends a curriculum model that is more integrated with spiritual practices.

The rapid growth of cross-platform applications has significantly increased the volume and diversity of sensitive user data processed across heterogeneous and distributed environments. Personally identifiable information, device identifiers, behavioral data, and financial information are routinely collected to support personalization, analytics, and service optimization. While these practices enhance application functionality and user experience, they also introduce substantial privacy risks, including unauthorized data access, device fingerprint–based re-identification, cross-user data leakage, and large-scale data breaches. These risks are further amplified by distributed processing architectures and extensive third-party library integrations commonly used in modern cross-platform systems. This study aims to systematically analyze privacy issues in cross-platform applications by examining the types of sensitive data involved, identifying dominant privacy threats, and reviewing state-of-the-art privacy-preserving mitigation strategies. A systematic literature-based methodology was employed, focusing on recent Scopus-indexed journal articles, conference papers, and book chapters. The analysis synthesizes findings using thematic categorization and a conceptual research framework that maps sensitive data sources to privacy threats and corresponding mitigation mechanisms. The results indicate that privacy risks in cross-platform applications originate not only from external attacks but also from internal architectural weaknesses, such as flawed authorization logic and excessive data sharing across system components. Privacy-preserving techniques including differential privacy, federated learning, blockchain-based data governance, secure multi-party computation, and fine-grained access control mechanisms are shown to provide stronger privacy guarantees compared to conventional centralized approaches. However, these techniques also present trade-offs related to system complexity and performance. Overall, the study highlights the importance of adopting a multi-layered, privacy-by-design approach to ensure sustainable, trustworthy, and regulation-compliant cross-platform application development.

The use of learning models can also be a factor that determines students' learning success. If the learning model used is appropriate, it can arouse students' interest in studying the material being taught in such a way that it influences the quality of learning outcomes. So the teacher must be able to create a learning model that creates a situation where the class of students can be active in the learning process. This research was carried out using the Classroom Action Research (PTK) method. Wardani & Wihardit (2018) stated that PTK is research conducted by a teacher in the class he teaches which aims to improve student learning outcomes. The subjects of this research were 36 students in class XI MIPA 3, consisting of 11 male students and 15 female students. P2K implementation is carried out in 2 cycles.

The Problem Based Learning learning model is a learning model that begins with giving problems to students where the problems given are everyday experiences or have been experienced by students. Then students solve the problems given to gain new knowledge. It is expected that students are able to learn knowledge related to these problems, as well as students have skills in solving problems. The purpose of this research is to increase student motivation in PAI subjects at Perlaungan Islamic High School. The research method used is descriptive qualitative. The data collection techniques used are in-depth interviews, observation and documentation. Data analysis was carried out through data reduction, data presentation and then drawing conclusions. The sources of data in this study are school principals, deputy heads of curricula, PAI teachers, and students. The results of the study show that: 1. Implementation of the Problem Based Learning learning model in PAI subjects at Perlaungan Islamic High School there are five stages, namely, student orientation to problems, organizing students to learn, guiding educators to search for data on a problem, developing and presenting the work , analyze and evaluate. 2. Student learning motivation, there are two learning motivations, namely, intrinsic motivation, intrinsic motivation there are three indicators namely, there is a desire and desire to succeed, there are encouragement and needs in learning, there are hopes and ideals, and extrinsic motivation, there are five extrinsic motivations indicators namely, there is appreciation in learning, there are interesting activities in learning, there is a conducive learning environment, teacher-student relationships, student-student relationships.    

Learning models develop as technology develops. Nowadays teachers can no longer teach using conventional teaching methods only but they also have to use technology for teaching. The use of technology in teaching does not mean that you have to abandon old methods. However, combining the two could be a good alternative. One of the learning models is the hybrid learning or blended learning model. What is its application in teaching English courses at the Catholic University of Widya Karya Malang? This research explores the process of using hybrid learning in learning English at Widya Karya Catholic University Malang, especially in English subject . The method used in this research is a qualitative descriptive method, which provides an overview of the implementation of this learning method. It turns out that using this method provides many positive benefits both from the teacher's side and from the student's side.
