Abstract

One of the most crucial elements in a company is Human Resources (HR). To ensure a conducive internal climate within the company, creating healthy competition among employees can be achieved by selecting the best candidates. The process of selecting the best employees at PT. Gumara Trans Jaya Boja relies on criteria-based data without accurate calculations. The purpose of this research is to provide a system that can make decisions about high-performing employees using the TOPSIS method and to implement this method in determining the criteria for assessing high-performing employees to ensure accurate data for precise decision-making and optimal results. The system is built using the TOPSIS method (Technique for Order Preference by Similarity to Ideal Solution), with XAMPP as its server, PHP as the programming language, and MySQL as the database. The testing results of this decision support system were deemed valid, receiving a score of 3.7, or 'Good', from expert evaluators, and obtaining a score of 4.2, or 'Very Good', from users. In a comparative test, the newly designed system achieved an 84% level of system alignment with the assessment indicators, compared to the old system's 44% alignment. This research follows the 6-step R&D method.

Abstract

Securing image files is a crucial aspect in addressing information security challenges. Super encryption is an approach that combines various cryptographic algorithms to enhance data security. In this research, we implement Super Encryption by combining two algorithms, namely Route Cipher and VMPC (Variably Modified Permutation Composition). Firstly, we employ the Route Cipher to encrypt image files by rearranging the pixels in the image using a specific mapping scheme. Subsequently, we apply VMPC, a key-symmetric encryption algorithm, to encrypt the previously modified image. The use of VMPC as the second layer aims to provide additional security by incorporating efficient and secure key-symmetric encryption. The results of this research demonstrate that the combination of Route Cipher and VMPC provides strong security for image files. This method introduces a high level of complexity for attackers attempting to decrypt the image without the correct key. Moreover, this Super Encryption offers higher confidentiality and resilience against attacks on image files compared to using a single encryption algorithm.

Abstract

SDIT NIDAUL HIKMAH SALATIGA is a private school with more than 600 students. Despite the large number of students, administrative services are still manually performed, including writing and compiling payment receipts in Microsoft Excel, manual data retrieval, and printing invoices from Excel. This method is not only impractical and inefficient but also often leads to calculation discrepancies. This study aims to develop an information system using the CodeIgniter framework. CodeIgniter, with its Model, View, Controller (MVC) concept, provides ease in designing information systems. The implementation of the WhatsApp API aims to create an up-to-date system by introducing WhatsApp notification features containing detailed billing and transaction information to parents/guardians of students. The research also aims to design a practical and effective information system in school administration services, making it easier and faster to perform administrative tasks. Through validation conducted by experts and users, it can be concluded that this system has received excellent ratings and can be applied as a tool for school administrative payment services, with revisions made if any issues are found. User Acceptance Testing (UAT) was conducted on sample respondents by asking users to try accessing the system and provide feedback by completing the provided questionnaire. From the test results, respondents gave a total score of 90% for ease of use, 86% for appearance, and 91% for functionality, indicating that users strongly agree that this school payment information system is easy to operate, has comprehensive features, and facilitates administrative services.

Abstract

The idea of network chunks being described as virtual subsets of the physical resources of 5G infrastructure is used in standards for 5G communications. The efficiency of ML predictors for traffic prediction in 5G networks has been established in recent research so that it becomes to assess the capability demands of each network slice and to see how it progresses as a large number of network slices are deployed over a 5G network over time to be very important. The main objective of this research is to establish the model that has the potential to help network management and resource allocation in 5G networks with machine learning performance analysis in predicting network traffic on high-dimensional spatial-temporal cellular data, in addition to investigating the effectiveness of various neural network models in traffic prediction from univariate and multivariate perspectives. The research method used is a quantitative research method using correlation analysis, statistical analysis, and distribution analysis on the temporal and spatiotemporal frameworks developed to predict traffic from a univariate and multivariate perspective. To predict 24-hour mobile traffic requires combining spatial and temporal dependencies. The univariate analysis will be carried out by applying a temporal framework that includes FCSN, 1DCNN, SSLSTM and ARLSTM to capture temporal dependencies. The results of various experiments in this study show that the proposed spatiotemporal model outperforms the temporal model and other techniques in the mobile traffic forecasting literature including internet, SMS, and calls.
