Abstract

Yadika 13 Tambun Vocational School has criteria where the school does not yet have a system that can support a decision. The decision support system (DSS) for selecting exemplary teachers in appreciating teacher performance presentations that have been made while teaching staff is expected to increase motivation so that they can improve their performance. Many DSS methods are used to find a decision in this study. The method to be used is VIseKriterijumska Optimizacija I Kompromisno Resenje, (VIKOR) which can produce the best alternative in the form of ranking of an existing sample by looking at the utility values and weights of each sample. This study describes the design of a decision support system for conducting assessments in selecting exemplary teachers at SMK Yadika 13 Tambun. System design using UML (Unified Modeling Language). The decision support system (DSS) is very helpful for those who will carry out the assessment process, before there was a decision support system the school always found it difficult to assess because it took quite a long time, the assessment was still done manually, it was difficult to calculate the assessment, sometimes there is an error in the assessment results. Therefore, this decision support system, it can help the school minimize these problems.

Abstract

This research aims to produce an output in the form of a cooperative sales application to its members using a 13.56 MHz RFID membership card. The research was conducted at Toko Koperasi Ubhara Jakarta Raya, which is a cooperative owned by employees of Universitas Bhayangkara Jakarta Raya, from January 2024 to February 2024. The cooperative membership card, which contains a 15.56 MHz RFID chip, can be used to validate cooperative member data when shopping at the cooperative store. With this application, it is hoped that it can simplify sales transactions for members and minimize input errors by store personnel. The system development method in this research uses the prototype method, the application is developed using native PHP programming language, and the database used is MySQL. The application created is expected to assist the cooperative in selling its products using a 13.56 MHz RFID card for better data management and quick presentation of sales reports.

Abstract

Traditional learning methods that rely on books and static images often fail to effectively capture children's attention and help them understand the material. This is one of the challenges in increasing learning motivation. To address this issue, an Android-based AR application was developed to teach vowel letters to kindergarten children. By using the fast corner detection algorithm and Unity3D, AR offers a more engaging and effective approach compared to conventional methods. The implementation stages include designing, developing, and testing the application by involving kindergarten children as research subjects to assess the effectiveness of the application. The goal of this PKM is to enhance children's interest in learning, facilitate the understanding of vowel letter concepts, and provide an innovative and interactive learning method. Research results show that AR has the potential to increase children's interest in learning and facilitate the understanding of vowel letter concepts.

Abstract

Social assistance is one of the government's programs aimed at helping people in need. However, the process of applying for social assistance often faces issues related to data security, particularly the personal data of aid recipients. This research aims to implement the Advanced Encryption Standard (AES) algorithm with a 128-bit key (AES-128) in the social assistance application system to enhance data security. The system development method used is the prototype approach, which allows for iterative and participatory system development. The results show that the implementation of AES-128 can effectively secure sensitive data, such as identification numbers, addresses, and financial information. This system is expected to be a solution for increasing public trust in the social assistance application process.
