Abstract

This research purpose is to make easy the registration process of new students by personalizing the account page on admission online. Therefore, each user can manage their own needs and recognize the steps that must be taken to be a BINUS student. Analyses are performed towards the current working system and issues related to the system. Further is performing finding references related to the problem through literature study. Then, creating a UML diagram of the system design, user interface and database. Next is the programming phase and evaluation of the application . The results obtained is an online admission application with a personalized login page. It can be used to make easy the registration of new student or related issue at the many insttutions of Binus. It is suggested to create the mobile version of online admission for the future development.

Abstract

This research aims to help universities that do not have an academic information system and facilitate EPSBED data report to Directorate of Higher Education (DHE). The method used is the three first stages in the System Development Life Cycle (SDLC), which are systems engineering, requirements analysis, and design system. The result is a design of university business process, design of database, and design of user interface. This research finds that DHE has a specific data structure that can represent the basic activities of a study program. Therefore, this system design can be used for reporting of EPSBED data as well as for data collection of study program activities.

Abstract

Mobile applications today serve as versatile tools across diverse sectors, enhancing human productivity through specialized software on electronic devices. Implementation of the mobile application can also be applied to vehicles, with inspection and checking functions assisted by the Onboard Diagnostic-II (OBD-II) scanner. The research aimed to develop an integrated mobile application that utilized the OBD-II scanner and Data Acquisition System (DAS) to monitor vehicle health and provide timely service reminders. Vehicle information was taken by the DAS process into a Diagnostic Trouble Code (DTC) from the vehicle itself. The method applied the waterfall model, which consisted of communication, planning, modeling, construction, and evaluation. The problem analysis and requirements gathering for developing the application involves the interview method and Google Forms-generated questionnaires with 101 responses. Then, the research used OBD-II series ELM327 and ELM 327 IC devices for testing. The research results in an application developed for vehicle diagnostics using a recommendation system through notifications that provide vehicle health information and service time reminders to users. This application consists of eight modules, with the main module being able to provide recommendations for vehicle owners. These recommendations are helpful for users to maintain the health of their vehicles regularly. Further research is recommended to enhance the development of the application, aiming to create a more comprehensive user interface.
