There are many archives owned by AMNI Maritime University in Semarang. The archiving system carried out at the AMNI Maritime University Semarang is still not well organized and neat because it is only based on archive classification, so if you have to look for archives such as archive numbers or archive dates, you will experience problems because you have to find the files needed one by one in the filing cabinet. The sequential search algorithm can be applied to the search for employee document numbers at the Maritime University AMNI Semarang and works well as planned. The employee document archive information system at the Maritime University AMNI Semarang can be used to manage the employee document archive more optimally, controlled, well organized and maintained so that the archive is not easily damaged

Augmented Reality (AR) and Virtual Reality (VR) which are one of the top ten strategic technology trends for 2019 and continue to be developed massively in this 2020, have been widely applied in various mobile applications by many companies in this industrial revolution era 4.0. AR can be applied to help the promotion for housing developers where users can see the 3-dimensional shape of the types of houses offered, while VR allows users to explore each part of the house in a virtual 3D. Pre-existing brochures are used as markers for this application to work, so that AR and VR applications can be a complement to promotional media. The design method used in this paper is Research and Development (RnD). Salespeople can offer types of houses to prospective customers without having to print multiple brochures, but with just one brochure and one android smartphone to present, so the promotion costs are more efficient.

Technological developments encourage changes in the way decisions are made. In terms of stopping the application of urea fertilizer, farmers still rely on BWD observations. In this study, using the RnD method by directly observing the research location in the farmer group Gapoktan, in the village of Tosari, Kendan district and analyzing the problem then making a prototype which will be tested by experts. In this study, a tool was made using NodeMCU with TCS3200 sensor to detect color, which was then sent via the internet to the database using IoT technology. In this study, using several trials with different parameters of urea fertilizer use and the results of the TCS3200 sensor can detect colors according to what is on the BWD and send data to the database via the internet. In this system, farmers can recommend the use of suitable urea fertilizers outside a certain area so as to minimize errors in the observation on BWD, this will make the use of urea fertilizer to be the right dose.
