Abstract

Banyaknya ruangan dan luas gedung pada perkantoran atau mal seringkali menyulitkan pengunjung untuk mengetahui lokasi pengunjung saat ini, menemukan lokasi suatu tempat dan rute untuk menuju lokasi tersebut. Oleh karena itu,  pada penelitian ini dibuat sebuah aplikasi android yang dapat memetakan posisi pengguna dengan menggunakan wireless LAN dan pencarian rute menuju suatu lokasi. Metode yang digunakan untuk penentuan lokasi adalah Fuzzy Logic Indoor Positioning System yang dikombinasikan dengan Location Fingerprinting, sedangkan untuk pencarian rute digunakan Iterative Deepening A*. Metode ini terdiri atas 2 tahap, yaitu tahap offline dan online. Pada tahap offline, dilakukan survey terhadap lokasi yang bersangkutan untuk mengumpulkan data survey, yang berupa data Received Signal Strength (RSS) dari setiap access point yang terpasang. Sedangkan pada tahap online, pengguna mengirimkan data RSS ke server untuk ditentukan posisinya.Hasil pengujian menunjukkan bahwa proses penentuan letak sangat bergantung pada data fingerprint  yang dikumpulkan pada tahap offline. Sedangkan RSS yang merupakan data survey utama, sangat sensitif terhadap kondisi lingkungan. Peningkatan akurasi hasil penentuan letak dapat dicapai dengan menambah jumlah Access Point (AP) dan jumlah Reference Point (RP) yang optimal. Aplikasi ini nantinya dapat dikembangkan sehingga dapat digunakan ketika di dalam gedung maupun di luar gedung.

Abstract

Autolux Project is owned by DTT Multimedia B.V. Autolux is a platform for car lovers sharing their information about favorite or latest cars. The website was built in MODx (CMS framework) which considered being old and heavy by the company. With that very reason, a project to migrate the website from MODx into PhalconPHP (pure PHP framework) was started. Migrating website from MODx to PhalconPHP was a success, and to boost the website popularity, the first thing to do is to implement the SEO standards. Another demand by the company was for the website to be responsive and using OOP standarts. Responsive website can be reached by using the help of libraries. PhalconPHP already implemented OOP, thus the developer will follow the MVC pattern given and refine it by doing more separation of concerns. Later on, the developer also put more refinements on the website to boost the speed of page loading, support multilingual, and management system.
