A lecturer assistant is expected to be professional when dealing with the score or decision. Being professional, the lecturer assistant will be constantly respected by the students. The lecturer assistant should be able to make use of the time to keep the disciplinary. Selecting and determining the lecturer assistant at Computer Science of Unika St. Thomas Medan are conducted by the phases of selecting and taking value of the test score, the semester of lecturer assistant candidate, the number of classes to be assisted, cumulative grade point achievement, and the score of the assisted course. The Method of Multi-Objective Optimization on the Basis of Ratio Analysis (MOORA) is in the part of Decision Support System introduced by Brauers dan Zavadkas. This method is the multi-objective optimization technique which is successfully applied to solve the various complicated decision-making and well-used in terms of lecturer assistant selection due to its simple calculation and easiness to understand.

Purpose: Helping the learning process in early childhood through playing and learning activities with Augmented Reality technology.Design/methodology/approach: Using Augmented Reality technology with the Iterative Rapid Paper Prototype system development methodFindings/result: Based on tests conducted on 5 types of android devices, 10 samples of early childhood participants (4-5 years) and 5 groups of objects consisting of 10 types resulted in an increase in learning ability of 33.35% which was sourced from the measurement of the correct answers that were successfully obtained. between learning methods through pictures and learning using Augmented Reality technologyOriginality/value/state of the art: In previous research, the learning model was carried out on elementary school children (aged 6 years and over) and without the implementation of Augmented Reality technology

The advancement of information technology today is fueling the growth in the number of internet users. In the business world, the role of technology is very important, and it can be said that it has become a primary need for entrepreneurs in this period.

This study aims to increase knowledge through multimedia-based learning by utilizing information technology, namely Augmented Reality (AR) in knowing the types of traditional houses in North Sumatra province.Augmented reality (AR), is the appearance of real-world dimensions with virtual worlds in real time. In contrast to virtual reality which completely replaces what is in the real world, augmented reality is a process of adding or completing virtual reality. Augmented reality depicts a three-dimensional object on a marker as a unique pattern so that it can be recognized by the object processing application. Augmented reality can be used to create a more interactive recognition environment where users can interact directly with objects in cyberspace. The augmented reality application produced in this study was developed using the Vuforia Software Development Kit. In addition, the resulting application runs on the android mobile platform, which is expected to provide easy access for users
