Internet reactor laboratory application design on android client devices

Preparation of human resources (HR) is important for the construction and operation of the nuclear power plant (NPP) since the project preparation phase. Preparation is carried out through education and training related to nuclear reactors. The use of nuclear reactors as learning laboratories is needed to support these activities. This research aims to design an internet reactor laboratory (IRL) application that can be operated on android devices. The application developed using LabVIEW data dashboard software with data source from the IRL database. The application is evaluated to determine application compatibility with various screen sizes of Android devices, delay time, data accuracy level, and satisfaction assessment of IRL application users. The IRL program design results consist of IRL host computer programs as a data center, and the IRL application. The test results show that the IRL application can be run on all aspect ratios with a minimum screen resolution of 640 x 360 pixels. The average delay time needed to call the first data is 4.089 seconds, and 1.234 seconds for the next data. The average data accuracy rate is 99.95% with the maximum accuracy is 100%, and the minimum accuracy is 99.10% in the reactor period data. Based on the assessment, the level of satisfaction of users of the IRL application was found to be in the category of satisfied, both overall, and in aspects of ease of use of applications, information quality, and interface quality.
