Abstract

The data contained ranging from business transactions to government is very large in size so we need a system that can sort and select the data. Intense competition in the business world, especially in the food industry or supermarkets, requires developers to find strategies that can increase sales. Data mining is used to find patterns and regularities in data sets that are hidden by using technology. In knowing the products purchased by consumers, developers can use market basket analysis, namely an analysis of consumer buying habits and then detect products that consumers often buy simultaneously using association rules. Search for associations or relationships between items taken from a relational database using an a priori algorithm to form candidate item combinations and then tested whether the combination meets the minimum support and confidence parameters which are the threshold values ​​given by the user. Furthermore, it is applied by performing query processing, decision making and so on. Data mining applications with the association rule method have been able to perform calculations correctly as expected. The knowledge generated by the application and manual calculations is 17.2% of all transactions, granulated sugar and pomegranate cooking oil are purchased simultaneously. And of all transactions that buy granulated sugar, 55.5% will buy Pomegranate Cooking Oil. 17.2% of all transactions, Pomegranate Cooking Oil and Granulated Sugar are purchased simultaneously. And of all transactions that buy Pomegranate Cooking Oil, 55.5% will buy granulated sugar.

Abstract

The advancement and rapid spread of the internet poses a challenge to provide more optimal network quality at the Ahmad Dahlan Institute of Technology and Business educational institutions (ITB-AD). To help manage the existing network, the campus uses a proxy as the main manager of the existing hotspot network. The problem experienced is that the hotspot login display still uses the default default from Mikrotik, blocking has not been applied to accessing adult content, the efficiency of available bandwidth has not been properly distributed, and there is no scheduled access to existing network users. The aim of this research is to optimize the quality of the ITB-AD hotspot network. To help solve problems that exist in research, researchers use the Network Development Life Cycle (NDLC) as a methodology in research. The results of this study are able to provide additional custom configurations for hotspot login displays, application of adult content blocking, burst bandwidth as bandwidth efficiency and implement access schedules for users in the hotspot network. The conclusion of the study is that using the NDLC method can optimize the quality of the ITB-AD hotspot network.

Abstract

An ad-hoc network is a topology that directly connects a wireless network between end users to other end users without using other connected devices. For example, a network between a computer and another computer uses wireless transmission media. The interface used is a wireless card or wireless USB or other end user network device. The implementation of this particular topology is very convenient and very easy because it does not require much configuration, just create an adhoc network as a station on one of the computers and then configure the IP address.

Abstract

In this study, a new neural network model (EfficientNet B1-B2) was sought for the detection of brain tumors in magnetic resonance imaging (MRI) images. The primary objective was to achieve high accuracy rates so as to classify the images. The deep learning techniques meticulously processed and increased the data augmentation as much as possible for the EfficientNet B1-B2 models. Our experimental results show an accuracy of 98% in the B1 version in Table II. This provides a potentially optimistic view of the application of artificial intelligence technology to disease diagnosis based on medical image analysis. Nonetheless, we must remind ourselves that the dataset we used has limitations in terms of the challenges it can pose. Although the number of potential variations of actual medical images constitutes a major challenge, it is not the only one. Most medical datasets are unbalanced, contain highly variable noise, have a slow internal structure, and are often small in size. Hence, our end goal is to help stimulate not only the field of brain tumor detection and treatment but also the development of more sophisticated classification models in the health context.

Abstract

The development of a web-based Decision Support System (DSS) using the Simple Additive Weighting (SAW) method to evaluate and select students eligible for assistance based on predetermined criteria has been successfully accomplished. The SAW method involves six assessment criteria: family members (0.1), parental employment status (0.15), residence status (0.1), monthly income (0.3), student absenteeism (0.15), and academic achievement (0.2). The primary aim of this DSS is to streamline the decision-making process for teachers and administrators at SDN Panunggangan 4. Employing this algorithm, the system automatically ranks students based on their highest scores to prioritize those deserving of assistance. The study was centered on 32 sixth-grade students. Moving forward, it is hoped that this application can be enhanced and implemented more extensively.

Abstract

Rewarding employees is one of the important strategies for improving motivation and performance within an organization. However, many companies face difficulties in determining which employees deserve rewards in a fair and objective manner. This research aims to develop a Decision Support System (DSS) that can assist in determining which employees are entitled to receive rewards based on several relevant criteria, using the Simple Additive Weighting (SAW) method. The SAW method is chosen for its ability to solve decision-making problems that involve multiple criteria with multi-attribute characteristics. The criteria used in this study include performance, discipline, contribution to the team, and initiative. The results of the study indicate that the application of the SAW method can produce objective and transparent decisions, as well as provide a solid basis for rewarding employees. The employee alternative with the highest score based on the SAW calculation is selected as the reward recipient, which is expected to enhance employee motivation and performance within the company. This research is expected to contribute to the development of a more systematic and data-driven reward system.
