The development of digital technology has brought significant changes to the e-commerce industry, including the improvement of data-driven services such as product recommendation systems. Marketplace Buket, which provides various types of bouquets online, faces the challenge of understanding consumer preferences to increase customer satisfaction and loyalty. To address this challenge, this study implements the Collaborative Filtering (CF) method as an approach in building a recommendation system capable of analyzing user behavior patterns based on consumer rating data for products. The CF method allows the system to identify user preferences by comparing similarities between consumer behaviors. By utilizing rating data, the system can recommend products that are relevant and in line with the user's interests, even if the user has never viewed or purchased the product before. This study tests the effectiveness of the recommendation system using real-world data and observing the results of recommendations given to specific users. The results show that the system can provide product recommendations with a high level of relevance, such as products I24 and I26 which are at the top of the recommendation list. In addition to providing relevant results, the system is designed with a simple interface for easy use by general users. The findings of this study indicate that the implementation of CF not only improves the quality of the user experience but also contributes to service efficiency and potential sales increases, including in intercity areas. Overall, this research provides an important contribution to the development of data-driven marketing strategies and lays the foundation for the future development of more complex recommendation systems.

The phenomenon of bullying that occurs in the pesantren environment is not only a social problem, but also reflects a crisis in the internalization of Islamic educational values. This study aims to examine the dynamics of bullying in Islamic boarding schools from a psychosocial perspective and Islamic educational values. With a literature study approach and qualitative content analysis, this study explores various theories, empirical findings, and expert views obtained from relevant journals, books, and scientific works. The results of the study show that the practice of bullying in pesantren often stems from power relations that are institutionalized through the hierarchy structure of seniority, as well as weak supervision of the process of internalizing Islamic values among students. The values of Islamic ukhuwah, justice, and compassion that should be the spirit of Islamic education are often eroded by a culture of silence, neglect, or even the wrong perception that bullying is part of discipline. In fact, the concept of Islamic education not only emphasizes the mastery of the knowledge of tools (tsaqafah), but also the formation of intellect ('aqliyah), soul (nafsiyah), and Islamic personality (syakhsiyah Islamiyah) based on a strong aqidah. Bullying prevention requires deeper Islamic character education, strengthening social control, and psychosocial approaches to maintain mental and spiritual balance of students. The implications of this study emphasize the importance of a holistic and civilized pesantren management strategy, by fostering an anti-bullying culture, creating a safe, harmonious, and harmonious learning environment that is in line with the main goals of Islamic education. Thus, pesantren are expected to be able to form students who are not only intellectually intelligent, but also have noble morals, high social spirit, empathy, and have a strong Islamic personality and full of integrity.

Rapid technological developments have penetrated various aspects of human life, including data and information security. Amidst the threat of data leaks and misuse, information protection has become crucial. One solution to maintain data confidentiality is to implement cryptography technology. Cryptography is the study of techniques to secure messages so they cannot be read by unauthorized parties. This process is carried out by encoding the original message (plain text) into an unreadable form (cipher text), which can only be understood by those who possess the key to decrypt it. This study used the Caesar Cipher algorithm, a form of classical cryptography. This algorithm uses a substitution method, where each letter in the message is shifted by a certain amount based on a predetermined key. Caesar Cipher is a symmetric algorithm, meaning the key used for encryption is also used for decryption. The security of this algorithm lies in the secrecy of the key, which is known only to the sender and recipient of the message. This method is relatively simple, but still relevant for securing data with low to medium sensitivity levels. This study used WhatsApp messages as the object to be encrypted using the Caesar Cipher algorithm. The results show that encrypted messages become unintelligible without prior decryption. This demonstrates that the Caesar Cipher can protect messages from unauthorized parties. Therefore, implementing this algorithm can be an initial solution for maintaining data confidentiality in digital communications, especially on platforms vulnerable to eavesdropping or unauthorized access. Its primary benefit is maintaining message integrity and confidentiality to prevent misuse.
 

Education is a conscious and structured effort aimed at creating an environment and process that actively facilitates learners in developing their full potential. This includes nurturing their spiritual and moral values, self-control, intelligence, strong character, and essential life skills required for personal development and meaningful contributions to society, the nation, and the global community. At its core, education serves to empower students to realize and utilize their capabilities for future life challenges. It acts as a foundational medium through which younger generations acquire essential life skills, enabling them to integrate effectively into society. Moreover, education plays a pivotal role not only in the personal growth of individuals but also in the advancement of a nation. High-quality education is defined by its capacity to equip students with the competence to confront and resolve real-world problems. This notion becomes increasingly critical as learners transition from academic settings to the workforce and community life, where they are expected to apply their knowledge and skills practically. However, the success or failure of educational outcomes is largely determined by the curriculum. A well-designed curriculum should cultivate critical awareness and empower students to navigate complex social and professional environments. It should also promote creativity, critical thinking, and collaboration, which are essential skills in today’s rapidly changing world. Furthermore, education should not be viewed merely as a means to acquire knowledge but as a holistic process that fosters emotional intelligence and social responsibility. By integrating various disciplines and encouraging interdisciplinary learning, education can help students develop a broader perspective on global issues, such as climate change, social justice, and economic inequality. In addition, the role of educators is crucial in this process.
