Merancang UML (Unified Modelling Language) Aplikasi e-JO Departemen Instalasi PT. ANDS

Abstrak

In the current job order process, paper is still used as the medium for creating job orders, leading to difficulties
in document retrieval and archiving. Additionally, there is no adequate system for monitoring job orders, and the
submission process is notably time-consuming. To address these issues, this study has designed a web-based e-
JO system using UML (Unified Modeling Language) as a visual modeling tool to facilitate user understanding
and interaction with the system. The UML design was carried out as an initial step before application development
commenced. The system aims to enhance the efficiency and structure of the job order process. The UML employed
includes four types of diagrams: Use Case Diagram, Activity Diagram, Class Diagram, and Sequence Diagram.
The web-based e-JO application was successfully developed using UML and involves seven actors: Admin, User,
Dept. Head, Plant Head, Factory Head, Engineering Dept. Head, and Member.
