Abstract

Batam waters are one of the busiest shipping lanes in Indonesia, with high ship traffic density and complex movement patterns. This condition requires data analysis techniques that can accurately identify and adapt ship movement patterns. The purpose of this study is to study ship movement patterns using Automatic Identification System (AIS) data, and also to see how the K-Means and DBSCAN algorithms work in the data clustering process. The AIS data used includes geographic coordinates, observation time, speed, and direction of ship movement in Batam waters. This study includes the application of the K-Means and DBSCAN algorithms, feature extraction and normalization, and data pre-processing to improve data quality. Internal validation metrics used to assess cluster quality are the Silhouette Score and the Davies–Bouldin Index. The results of the study show that the DBSCAN algorithm has a better level of cluster cohesion and separation between clusters than K-Means. The K-Means algorithm produces a Silhouette Score value of 0.48 and a Davies–Bouldin Index value of 0.91, while the DBSCAN algorithm produces a Silhouette Score value of 0.62 and a Davies–Bouldin Index value of 0.67. In addition, DBSCAN can find sound data of 19.96% of the data set, which indicates abnormal ship movements or does not form a certain density pattern. The results show that the DBSCAN algorithm analyzes ship movement patterns with AIS data in the Batam waters better than K-Means. This research is expected to be the basis for the development of maritime information systems that help monitor ship traffic, make decisions about safety, and manage waters.

Abstract

Keterbatasan media promosi konvensional dalam menyajikan informasi teknis dan fungsional produk industri secara komprehensif menjadi kendala dalam strategi pemasaran digital, sebagaimana dialami oleh PT Gunung Mas Perkasa Abadi yang masih mengandalkan katalog dua dimensi serta penjelasan verbal dari tim sales pada interaksi Business-to-Business (B2B). Penelitian ini bertujuan untuk merancang dan mengembangkan prototipe sistem informasi promosi berbasis website yang mengintegrasikan teknologi Web-based Augmented Reality (Web-AR) dengan Quick Response (QR) Code guna menampilkan lima produk prioritas perusahaan dalam bentuk model 3D interaktif. Pengembangan sistem dilakukan menggunakan metode Multimedia Development Life Cycle (MDLC) yang meliputi tahap concept, design, material collecting, assembly, testing, dan distribution, dengan memanfaatkan aset yang bersumber dari data produk perusahaan. Sistem dikembangkan berbasis browser untuk meningkatkan aksesibilitas pengguna tanpa memerlukan instalasi aplikasi tambahan. Hasil pengujian teknis menunjukkan bahwa seluruh fungsi utama sistem berjalan sesuai dengan spesifikasi yang dirancang. Teknologi Web-AR mampu mentransformasikan representasi produk dua dimensi menjadi objek tiga dimensi interaktif secara real-time, sementara QR Code berfungsi sebagai media akses yang cepat dan akurat. Temuan ini mengindikasikan bahwa integrasi QR Code dan Web-AR secara teknis dapat diimplementasikan sebagai mekanisme penyampaian informasi promosi yang terintegrasi. Namun demikian, klaim keberhasilan penelitian ini dibatasi pada aspek fungsionalitas dan kelayakan teknis sistem, tanpa mencakup pengukuran efektivitas promosi, persepsi pengguna, maupun dampaknya terhadap peningkatan penjualan
