Basically, the use of internet activities in companies is very dense, causing various problems, among the problems encountered related to internet connection is bandwidth usage that has not been optimally regulated, so that no matter how much bandwidth capacity is available, it will not meet the needs of internet bandwidth usage if it is not managed properly. . In order for internet user bandwidth allocation to be distributed evenly, bandwidth management is needed to overcome the existing bandwidth limitations. Bandwidth management aims to find a solution so that all user computer devices get internet bandwidth allocation and can find out how to manage good bandwidth so that user devices get a fair or even distribution of bandwidth. The methodology for implementing bandwidth management with the queue tree method is to observe a running network system, identify problems, collect data, then design a configuration system. After going through the design process then carrying out the configuration stage, and if the configuration is successfully applied then proceed to the testing phase using several user computers assisted by using the wireshark application to find out incoming or received data packets, the next stage is monitoring using monitoring applications such as Torch Winbox, speedtest or wireshark and the final stage is evaluation or management such as configuration backups and so on. This research and testing also takes into account Quality of Services (QoS) parameters such as throughput, delay, jitter, and packet loss to find out in more detail the calculation of packet traffic that has been captured by the wireshark application. So that with good design, proper configuration, careful monitoring, an even, optimal bandwidth usage and quality internet connection is produced, so that the implementation of the queue tree method of bandwidth management provides an effective solution in managing bandwidth allocation.

Augmented Reality (AR) is revolutionizing human-computer interaction by blending the physical and virtual worlds. AR learning using markers or markerless has been widely used in learning media.

The approach is carried out using a superimposition technique that allows real 3-dimensional objects to become varied markers. The test results at the scan angle of the papercraft object used at a distance of 50cm with a slope of 1800, 50cm with a slope of 1300, 50cm with a slope of 900. Likewise the test results on respondents between ordinary learning using the AR application found 83.4% for ordinary learning and 100 % to study with the app. In the end, this research tries to present a new method in markers with a more interesting and real Superimposition technique.

In software development, it is necessary to plan carefully, so that the software developed is in accordance with user needs. Software development without good planning will result in a patchwork of software development. To avoid the patchwork of software development, a software development framework is required. The research "Developing Restaurant Operational Applications With Scrum Framework (Case Study: PT.XYZ Restaurant)" aims to develop restaurant operational software at PT. XYZ. The software development framework used in software development uses the Scrum framework. The Scrum framework is a variant of the Agile framework. Agile has a dynamic way of working (iterative and incremental). The Scrum framework has a product backlog, then the product backlog is divided into several sprints. One sprint will be run in one iteration, so that each end of a product sprint that meets the definition of “Done” must be achieved. The use of the Scrum framework emphasizes communication and collaboration between various stakeholders. The result of this research is a software that helps restaurant operations at PT. XYZ starting from master files, transactions files, to reports files. By using the Scrum framework in application development, the application development life cycle is created. Software development can be done by implementing an enterprise architecture that already belongs to a company.
