The research objectives are to design a web-based application that can help make the best employee selection report process easy and fast, design an application that can calculate normalization to determine criteria and weights according to the analytical hierarchy process (AHP) method, and design an application that can manage data -Alternative data needed for the selection of the best employees. The stages of data collection in this study consisted of 3 (three) stages namely; observation, interview, and literature study. UML (Unified Modeling Language) is used as an approach for modeling while the Analytical Hierarchy Process (AHP) method is applied in the best employee assessment application. The results of this study can facilitate the selection of the best employees to be faster with accurate results by using the best employee selection application by implementing the Analytical Hierarchy Process (AHP) method using the PHP and MySQL programming languages.

Android-Based Car Driving Simulation Application is an application used to obtain information about driving and caring for a car using smartphone support media. This is based on the increase in car accidents from year to year. The lack of information and the lack of knowledge of car drivers about driving information has made the author make a Car Driving Simulation application for the needs of visitors in using and accessing this application. Remembering technology is like a gadget that is no longer difficult to obtain, in fact it is possible for all people to have it. The application is designed with a smartphone that uses the Android operating system. Applications are made based on information needs for motorists. This application has gone through the stages of testing on four Android smartphone devices. This application is made using Phonegap with HTML and CSS programming languages and runs on the Kitkat version of the Android operating system as a minimum requirement.
