Abstract

Abstract:  This journal explains how to design and build an application that can perform calculations using apriori algorithm. The workflow applied in this study is a sequential workflow (waterfall method). The application built is a website-based application that can be accessed using a web browser. To make application design in this research, UML modeling is used. The model that has been designed using UML will be implemented into PHP coding which can then be run via a web browser. The supporting tools used are XAMPP which provides apache and mysql services. From the test results, it is found that the application of apriori algorithm based on this website is able to perform calculations using the a priori algorithm accurately. These results are proven by comparing the results obtained from manual calculations with the results of calculations performed by this application using a sample of the same data. Keyword: apriori algorithm; data mining, modeling; mysql; php; uml Abstrak: Dalam jurnal ini dijelaskan bagaimana merancang hingga membangun sebuah aplikasi yang dapat melakukan perhitungan dengan menggunakan algoritma apriori. Adapun alur kerja yang diterapkan dalam penelitian ini adalah alur kerja yang berurutan (metode waterfall).  Aplikasi yang  dibangun adalah aplikasi yang berbasis website yang dapat dikases menggunakan web browser. Untuk membuat perancangan aplikasi dalam penelitian ini, digunakan pemodelan UML. Model yang telah dirancang dengan menggunkan UML akan diimplementasikan kedalam koding PHP yang nantinya dapat dijalankan melalui web browser. Adapun tools pendukung yang digunakan adalah XAMPP yang menyediakan service apache dan mysql. Dari hasil pengujian didapatkan bahwa aplikasi perhitungan algoritma apriori berbasis website ini mampu melakukan perhitungan dengan menggunakan algoritma apriori secara akurat. Hasil ini dibuktikan dengan cara membandingkan hasil yang didapat dari perhitungan manual dengan hasil perhitungan yang dilakukan oleh aplikasi ini dengan menggunakan sebuah sampel data yang sama. Kata kunci: algoritma apriori; data mining; mysql; pemodelan; php; uml
