Pantai merupakan tempat wisata yang mudah dijangkau di daerah maritim untuk menghilangkan kejenuhan ditengah rutinitas sehari-hari. Pulau Bintan adalah pulau yang didominasi lebih dari 90% wilayahnya oleh laut. Sebagian besar dari penduduk di bintan sangat bergantung pada hasil laut, selain itu sektor pariwisata terutama lautannya menjadi daya tarik wisatawan lokal maupun wisatawan internasional. Keindahan pantai khususnya di Pantai Trikora Bintan, Kepulauan Riau yang merupakan lokasi strategis karena berbatasan dengan Singapura dan Malaysia. Pengunjung wisata pantai trikora setiap tahunnya meningkat namun memiliki masalah terkait kesadaran pengunjung yang belum merata untuk memelihara kebersihan. Kegiatan pengabdian ini dilakukan untuk mengajak kepada masyarakat sekitar untuk peduli dan juga mengedukasi untuk memisahkan sampah sesuai jenisnya. Jenis sampah diklasifikasikan dengan menggunakan ukura meso (0,5-2,5cm) atau biasa disingkat LCS yaitu litter classification system. Beberapa temuan sampah dilokasi pantai trikora yaitu sampah plastik, kayu, busa plastik, kaca dan keramik. Sampah plastik menjadi penyumbang terbanyak yaitu 43%, disusul kayu 24%, busa plastik 19%, kaca dan keramik 14%.

The suitability of technology can only be assessed in the context of the overall process of social and economic development. Means of assessment include technology assessment where one examines the broad impact of a technology, and socio-economic opportunity analysis where one starts from social needs and looks for technological solutions. The integration and balance of different levels of technology is as important as the selection of individual technologies. Superior Engineers in the 21st Century do not design for the community, but design with the community and enable design by the community. With the right training and education, engineers can help change communities for the better by equipping community members to meet their own needs and implement their own design responses. Higher Education Institutions are present in society and have a very big role in building the nation, Higher Education also occupies a strategic position in making changes in society through the function of transforming Human Resources (HR), Science and Technology (IPTEK) and social through the implementation of Tridharma activities which includes education, research and community service. With this background, the Raja Ali Haji Maritime University Maritime Engineering Study Program carries out Community Service in the form of Appropriate Technology (TTG) training in the form of ship model making training or known as Hydromodelling at the Hang Tuah Tanjung Uban Naval Vocational School, Bintan, Riau Islands. The training stages include introducing maritime insight and technology, explaining ship parts and then providing training related to ship design and production. The training has received a good response from the school and the students showed enthusiasm in carrying out each stage of the training.

The development of transportation infrastructure has a multidimensional impact in driving economic growth and regional integration. The Jakarta-Bandung High-Speed Rail project is expected to reduce traffic congestion and improve connectivity and mobility efficiency. However, its success must be assessed not only from the technical aspects and physical completion, but also the effectiveness of public investment, long-term economic impacts, and environmental sustainability. The main challenges of this project include land acquisition, financial uncertainty due to debt-based financing schemes, and integration with other transportation systems. From a social perspective, this project has the potential to drive urbanization around the route, but also poses the risk of development inequality and gentrification. Ecological impacts are also a concern, especially in terms of land degradation and operational energy consumption. This study uses a literature study method with content analysis to evaluate the success of the project based on economic, social, and environmental indicators. The results of the study show that the effectiveness of this project is highly dependent on operational optimization, integration of transportation modes, and the sustainability policies implemented. With transparent governance and appropriate risk mitigation strategies, this project has the potential to provide long-term benefits for economic growth and community welfare, as well as being a model for more inclusive and sustainable transportation infrastructure development in Indonesia.

Veterinary clinics routinely generate transactional data that contain valuable information about both operational workflows and customer preferences. This study aims to differentiate between procedural and customer-driven service patterns by applying the FP-Growth association rule mining algorithm to 1,000 anonymized transactions comprising 94 unique items, collected from a veterinary clinic in West Java, Indonesia, during 2023. Two distinct analytical scenarios were constructed: Scenario 1 includes all services (procedural and customer-driven), while Scenario 2 excludes procedural items such as “Vet” and “Visit Dokter” to focus solely on client-initiated behaviors. Data preprocessing involved aggregating transaction items into a market basket format suitable for frequent pattern mining. The FP-Growth algorithm was employed to extract association rules, evaluated using support, confidence, and lift metrics. Results from Scenario 1 revealed rule patterns reflective of standard clinical protocols and operational dependencies, informing bundled service packages and inventory management. In contrast, Scenario 2 uncovered customer-driven associations, highlighting opportunities for personalized promotions and service innovation. The comparative analysis demonstrates the utility of scenario-based association rule mining for both operational optimization and customer engagement. While the findings provide actionable insights for clinic management, further validation with practitioners and implementation in multi-clinic settings are recommended to confirm real-world applicability and enhance generalizability.

This study aims to segment customers of a veterinary clinic using a combination of Recency, Frequency, Monetary (RFM) analysis and the K-Means clustering algorithm. Transactional data from December 2024 to April 2025 were processed to generate key customer features, followed by min-max normalization to ensure comparability across variables. The segmentation was conducted in AI Studio 2025, with cluster quality evaluated using cluster distance performance and Davies-Bouldin Index. The analysis resulted in four distinct customer segments: the majority were passive customers with low transaction frequency and spending, while a smaller group showed high purchasing activity and made a significant economic contribution. This study demonstrates the effectiveness of automated data mining tools in uncovering meaningful customer profiles in a veterinary service context. The results provide a practical basis for targeted marketing, customer retention strategies, and service improvement in veterinary clinics. This approach offers valuable insights for data-driven decision making and represents a novelty for veterinary service management in Indonesia. Keywords: Customer Segmentation, RFM Analysis, K-Means Clustering, Veterinary Clinic, Data Mining.

Budidaya jangkrik merupakan salah satu alternative mata pencaharian yang semakin berkembang seiring meningkatnya permintaan jangkrik sebagai pakan burung, ikan hias, serta kebutuhan industri makanan dan farmasi. Namun demikian, masih banyak peternak yang menerapkan metode konvensional, khususnya dalam hal pengaturan suhu dan kelembapan kandang yang menjadi faktor penting dalam keberhasilan budidaya. Kegiatan pengabdian kepada masyarakat (PKM) ini bertujuan untuk memberdayakan peternak jangkrik lokal di Desa Toapaya, Kabupaten Bintan, melalui penerapan sistem monitoring lingkungan berbasis Internet of Things (IoT) menggunakan platform Blynk dan mikrokontroler Arduino. Alat yang dirancang mampu memantau suhu dan kelembapan secara real-time serta mengirimkan notifikasi langsung ke perangkat pengguna, sehingga memungkinkan peternak untuk segera melakukan tindakan korektif saat kondisi kandang berada di luar batas ideal. Kegiatan ini meliputi observasi lokasi, wawancara, studi pustaka, perakitan alat, instalasi, pengujian, hingga evaluasi pasca implementasi. Hasilnya menunjukkan bahwa sistem dapat berfungsi secara efektif dalam menjaga kestabilan lingkungan kandang, menurunkan tingkat kematian jangkrik, serta meningkatkan produktivitas budidaya. Selain menghasilkan solusi teknologi praktis, kegiatan ini juga berkontribusi dalam membangun masyarakat cerdas dengan mendorong literasi teknologi di kalangan peternak daerah.
