Abstract

ABSTRAK Ada banyak jenis kejahatan dari rendah ke tingkat tinggi asalkan ada kesempatan. Departemen kepolisian di setiap negara telah mencoba untuk mengurangi jumlah kejahatan ini, namun pada kenyataannya, jumlah kejahatan selalu tumbuh setiap tahun. Alih-alih menangkap kriminal, kita bisa meminimalkan kejahatan dengan menurunkan peluang tindakan pidana. Sebagai contoh, kita dapat menambahkan perangkat keamanan untuk melindungi aset kita. Kami mengusulkan sistem untuk mendeteksi jika ada seseorang memasuki ruangan dengan membandingkan pola setiap beberapa waktu. Ada banyak teknik pola yang cocok, tapi yang sederhana adalah dengan menghitung jarak dengan menggunakan Metode Jaccard. Jika ada pola yang berbeda dari pola sebelumnya yang tertangkap oleh webcam, sistem akan membuat alarm (suara dan simbol). Untuk tujuan ini, kita menggunakan aplikasi capture yang memiliki kemampuan untuk menangkap gambar secara berkala dan sistem yang membandingkan setiap gambar dari penangkapan sebelumnya. Hasil pengujian menunjukkan bahwa sistem yang diusulkan kita bisa mendeteksi setiap orang yang datang ke daerah kami webcam. Kata Kunci: Surveillance, Pencocokan Pola, Jaccard ABSTRACT There are a lot of kinds of crime from low to high level as long as there is a chance. The police department in every country has tried to decrease crime's number, but in fact, the crime's number always grows every year. Instead of catching the criminal, we can minimize the crime by lowering the opportunity of criminal's action. For example, we can add a security device to protect our assets. We proposed the system to detect if there is someone entering the room by comparing pattern every couple of time. There are many pattern matching techniques, but the simple one is by counting its distance using Jaccard Method. If there is a different pattern from previous pattern that caught by a webcam, the system will create an alarm (sound and symbols). For these purpose, we use a capture application whose ability to capture an image periodically and the system that compare every image from previous capture. Testing result has shown that our proposed system could detect every people that come to the area of our webcam. Keywords: Surveillance, Pattern Matching, Jaccard

Abstract

Jakabaring Sport City (JSC) is an integrated sports facility complex and a public tourist spot in Palembang. Due to its extensive area and numerous facilities, visitors need a map with distinct markers for the landmark to make it easier when walking around. Recent technology advancements and its expanding role in various fields invites the question on how to integrate technology in the tourism industry. This journal aims to create an android-based digital map application with augmented reality (AR) as a guiding medium that will display directions towards the Jakabaring exit gate. This app is built using Maps SDK for Android to build the digital maps, Navigation SDK for Android to run navigation, and Maps for Unity to display AR objects that will show the directions towards the exit. The development focuses on a location-based service using GPS to track the user's whereabouts and provide real-time location data around the user. This application has a location search feature, a guiding direction (route and navigation) to a designed location, and an AR camera feature to display where the JSC exit gate is located. Every feature is working well and able to help users while visiting JSC. However, this application could still be improved in the AR feature because on its current version, it is only able to display directions to the JSC exit gate when users are within a radius of one kilometer or less to the exit.
