Abstract

Hukum di Indonesia berjumlah sangat banyak dan saling berhubungan atau merujuk antara satu sama lain. Salah satu fenomena hukum yang ada di Indonesia yaitu terdapat kemiripan aturan hukum sehingga menimbulkan masalah yaitu aturan hukum yang tumpang tindih dan tidak sinkron. Ketika aturan hukum yang baru akan dibentuk, sebaiknya tersedia tools yang dapat melakukan pemeriksaan terlebih dulu terhadap hukum lama sehingga tidak tumpang tindih dan sinkron. Knowledge graph (KG) digunakan pada penelitian ini untuk merepresentasikan hukum-hukum yang ada di Indonesia. Penelusuran KG tersebut akan dibantu dengan teknologi graph mining. Pada penelitian ini, dibahas pula aspek-aspek filsafat sains pada beberapa penelitian terdahulu yang berkaitan dengan topik penelitian ini.

Abstract

A museum is an institution intended for the general public. One of them is the Sudirman Museum, which is located at Magelang City, Central Java. This museum contains relics of General Sudirman that were used during his war. Each museum has different rules in terms of the interaction between visitors and objects on display in the museum. Sudirman Museum is one of the museums that do not allow not to touch objects directly and display information incomplete on each item in the collection. This study aims to overcome the limitations of interaction between museum visitors and objects on display in the museum. This study develops a mobile application based on an operating system based on Augmented Reality that can add to the attraction of the Sudirman museum for visitors so that it is expected to attract visitors to the museum. The results of this research are in the form of an Android application that simulates the contents of the museum and its information through a 2D display on a cellphone screen. In this way, visitors are expected to experience the experience of being in the museum through Augmented Reality. This Augmented Reality-based Android application is designed using the waterfall method and is made using the Unity3D, Vuforia SDK, and Blender applications
