Abstract

Students in the campus environment often miss important information conveyed through WhatsApp or unstructured communication media. In addition, lecturers are not always able to monitor every message in the group, causing announcements to get lost among many other messages. This issue requires a solution in the form of a centralized and efficient campus activity management application. This application aims to make it easier for lecturers to deliver announcements directly and in an organized manner, while also serving as an integrated platform that supports communication between lecturers, students, and campus administration. The methodology used in this study includes internal data analysis based on daily operational observations on campus, as well as consultations with lecturers and students without involving surveys or questionnaires. The analysis is conducted to assess the technical, economic, operational, legal, and scheduling feasibility of the application development.The results of this study show that this application is feasible to develop using React Native for cross-platform development, Java script for the backend, and Firebase as the database. This application is also designed to comply with data security and privacy standards in accordance with regulations in Indonesia. With a simple and user-friendly interface, this application is expected to facilitate information delivery, save time, and improve the efficiency of campus activity management.

Abstract

Penentuan rute terpendek dalam sistem navigasi pariwisata memiliki peran penting dalam meningkatkan efisiensi perjalanan wisatawan, terutama di kawasan yang memiliki banyak destinasi seperti Danau Toba. Penelitian ini bertujuan untuk mengimplementasikan algoritma Dijkstra dalam pencarian rute tercepat antar lokasi wisata utama di kawasan Danau Toba. Metode yang digunakan adalah pendekatan kuantitatif berbasis pemodelan graf, di mana simpul-simpul (nodes) merepresentasikan titik-titik wisata dan sisi (edges) menunjukkan hubungan antar lokasi yang diukur berdasarkan jarak aktual dari Google Maps. Simulasi dilakukan menggunakan titik-titik wisata yang direpresentasikan sebagai node A hingga L, yaitu: Balige (A), Sitorang (B), Dolok Sanggul (C), Porsea (D), Hutagalung (E), Parapat (F), Parbuluan (G), Dolok Pardamean (H), Paropo (I), Tiga Rungu (J), Saribu Dolok (K), dan Merek (L). Salah satu contoh hasil simulasi menunjukkan bahwa lintasan A → B → D → F → H → K → L merupakan rute tercepat dengan jarak tempuh terpendek. Implementasi algoritma Dijkstra terbukti efektif dalam menyelesaikan persoalan penentuan rute optimal berdasarkan parameter jarak. Temuan ini berpotensi untuk diterapkan dalam pengembangan sistem navigasi lokal berbasis wisata guna menunjang kenyamanan dan efisiensi perjalanan. Penelitian selanjutnya disarankan untuk mengintegrasikan variabel waktu tempuh, kondisi lalu lintas secara real-time, dan preferensi pengguna untuk hasil rekomendasi rute yang lebih relevan.
