The intersection of Kentungan is one of the intersections that connects North Ringroad Road and Kaliurang Street which looks increasingly stuck in Yogyakarta. This is due to an uneven increase in vehicle vehicles to road infrastructure. The peak of traffic jam at Intersection of Junction often occurs at 16.00-17.30 WIB. The problem at this junction is the amount of time delay and the length of the queue. One way to reduce congestion problems at the Intersection is to construct road infrastructure, one underpass. Based on these problems, research on the effect of underpass application on congestion parameters at several other intersections adjacent to the intersection of Kentungan. This research is a Multi Channel Multi Phase model configuration, by creating an underpass model of the Autodesk Infraworks 360 software. Before modeling underpass conditions, it is done in advance of the existing model of Intersection of Kentungan. The data inputted to this existing model is the total data of vehicles crossing the intersection of Kentungan for one hour. Verification model in this research is done by visual testing and check the duration of green light at the time of simulation done. Validation in this research is done by using hypothesis test, paired t-test. Then the parameters for validation are data ie the average waiting time of the vehicle, the maximum queue length and the number of vehicles passing through the green light in one cycle.In this study using two scenarios, in scenario 1 is the underpass model with the condition of the intersection and the scenario 2 is the underpass model with the roundabout condition. The results obtained from both scenarios are compared with the existing model results. The compared parameters are the average vehicle delay time and maximum queue length on each approach. It is expected from the comparison analysis to show that the Kentungan Intersection after the built underpass has decreased significantly on the average delay time and maximum queue length .

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%.

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.

The rapid advancement of Information and Communication Technology (ICT) has significantly transformed educational practices by introducing innovative and interactive learning tools. One such technology is Augmented Reality (AR), which merges real-world environments with virtual elements in real-time, providing immersive and engaging educational experiences. This community service activity aimed to enhance digital literacy among teachers and students at SMKN 5 Tanjungpinang through the introduction and practical demonstration of AR as an interactive learning medium. The implementation involved presenting the basic concepts of AR, hands-on demonstrations using mobile-based AR applications featuring realistic 3D models of ships, and simulations of maritime conditions using AR models. These simulations allowed participants to explore vessel scenarios and behaviors in various sea conditions, thus bridging theoretical concepts with practical visualization. Evaluative feedback, gathered through interviews and direct observations, indicated that the AR sessions significantly improved participants' understanding of complex visual-spatial concepts inherent in maritime education. Participants also expressed high enthusiasm, suggesting strong acceptance and potential for broader integration of AR technologies in vocational education. This initiative underscores the importance of interactive and simulation-based technologies in education, particularly in technical fields requiring detailed visualization and practical comprehension.

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.
