One of the three main factors influencing population dynamics is migration, along with births and deaths. Changes in population structure will definitely be influenced by migration. If in-migration is more than out-migration, the population will increase, but if out-migration is less than in-migration, the population will decrease. Therefore, it is necessary to know the grouping of regions based on population migration levels. To carry out this grouping, it is necessary to use Data mining methods. In this research, the Data mining used is Clustering using the K-Medoids algorithm. This method divides each district into predetermined groups. The K-Medoids method was chosen because it uses physical data that is not abstract and clear, which is suitable for the problem of grouping population migration data. By grouping migration levels based on districts/cities in West Java, it will be known which districts/cities in West Java have high levels of incoming migration, medium migration and high outmigration. Then recommendations can be given to the local government according to the migration level category.

Inflation is a general tendency to increase the prices of goods and services, and it happens all the time. when the prices of domestic goods and services rise, inflation will rise. Depreciation causes the prices of goods and services to rise. Uncontrolled inflation can result in losses for society and the government. Therefore, an appropriate study is needed to map the dynamics of inflation in a region. One way to map the inflation rate is clustering. Clustering is dividing data into groups with the same characteristics. The author took the initiative to analyze the urban inflation rate in Indonesia from 2020 to 2022. The data is sourced from the Central Statistics Agency (BPS) website. This analysis uses the K-Means Clustering method with 5 clusters. the group with the highest inflation is in cluster 0, the high inflation group is in cluster 1, the moderate inflation group is in cluster 2, the low inflation group is in cluster 3, and the lowest inflation is in cluster 4. by categorizing the inflation rate of cities in Indonesia, it can be seen which cities in Indonesia have very high, high, medium, low and very low inflation rates.

This research investigates the social construction of ChatGPT technology in society by identifying and analyzing the factors that influence its adoption and utilization. Through this analysis, we aim to identify recent research trends, gaps, and future research opportunities. The study utilizes data from various international scientific journals indexed by Scopus to explore the application of social construction of technology techniques and their societal impact. The method used in this research is bibliometric analysis to uncover patterns in the study of the social construction of ChatGPT technology in society. The results show that user perceptions of ChatGPT are influenced by digital readiness, technological literacy, as well as perceptions of benefits and risks. Additionally, ChatGPT is closely related to the development of critical skills among students, supporting the enhancement of analytical and critical abilities. The research focus in the field of AI, particularly concerning social and economic impacts, is expanding. This study emphasizes the importance of AI in various aspects of life and its contribution to sustainable development, especially in higher education, where AI technology integration is involved. Educational institutions are encouraged to design policies to support learning and skill development through AI. This research has limitations, particularly in terms of sample size and methodology, which can be addressed in future studies by expanding the scope and methods of the research. Overall, this study enriches the understanding of the impact of AI technology, particularly ChatGPT, in higher education and provides a foundation for further research.

The rapid development of information and communication technology has had a significant impact in the world of education, including at the Vocational High School (SMK) level. The need for innovative and interactive learning media encourages the development of mobile applications as an effective learning tool. This research aims to design and build a simple mobile application that can be used by SMK students in Cirebon City as an additional learning media. The application was developed using the Android platform with the Java programming language and utilizing Android Studio as an Integrated Development Environment (IDE). The development method used is waterfall, which consists of the stages of needs analysis, system design, implementation, testing, and maintenance. The content in the application is adjusted to the SMK curriculum, especially in subjects that are practical. The test results show that the application runs well on various Android devices and gets a positive response from users in terms of ease of use and interface appearance. With this application, it is expected that the learning process will become more flexible, interactive, and support the achievement of student competencies optimally. In the future, the application can be further developed by adding features such as interactive practice questions, discussion forums, and integration with online databases to make it more dynamic.

Penelitian ini membandingkan kinerja Support Vector Machine dan Naive Bayes untuk analisis sentimen komentar demonstrasi DPR pada 25 agustus 2025, mengidentifikasi faktor yang memengaruhi prediksi, serta memahami peran preprocessing dan fitur TF-IDF dalam menghasilkan klasifikasi yang stabil. Penelitian ini menggunakan komentar dari youtube berjumlah 17.335 komentar yang diproses melalui tahapan eksplorasi data, pembersihan teks, pelabelan berbasis lexicon berbasis bootstrapping, dan ekstraksi fitur utama (TF-IDF unigram/biagram). Hasil penelitian menunjukkan bahwa Support Vector Machine memberikan akurasi lebih tinggi yaitu 98% dibandingkan Naive Bayes memberikan 88% karena cenderung bias pada kelas mayoritas . Perbedaan performa dipengaruhi oleh struktur data, distribusi kata, serta sensitivitas model terhadap fitur yang tidak merata. SVM mampu memaksimalkan pemisahan antar kelas sehingga lebih stabil pada ruang fitur berdimensi tinggi, sedangkan Naive Bayes menghadapi kesulitan dalam mengenali pola sentimen ketika kelasTidakSeimbang mendominasi. Penelitian ini menegaskan bahwa preprocessing dan representasi fitur TF-IDF berperan besar dalam mengurangi noise serta meningkatkan kualitas pembelajaran model. Penelitian ini menyimpulkan bahwa SVM lebih sesuai digunakan untuk analisis sentimen komentar politik di Indonesia. Temuan ini memberi dasar empiris bagi pengembangan metode analisis sentimen pada isu sosial yang memiliki dinamika bahasa dan variasi konteks yang tinggi.
