Abstract

The MySQL database system is one of the database systems that is widely used in the world, both for personal and corporate purposes. However, the increasing number of cyber attacks occurring on database systems makes it increasingly important to secure data security in database systems. Cyber attacks can be via SQL Injection or hacking via connection commands to the database using the application whose database you want to hack. This is the focus of the problem, so it is necessary to secure connections to the database using cryptographic algorithms. This research aims to improve the security of the MySQL database system by implementing the Caesar Cipher cryptography technique and the Stout Codes compression technique in connection commands to the database via a client application built using the Visual Basic programming language. The testing method used in this research is experimental, where the MySQL database system is tested using ordinary connection commands and connection commands that have been encrypted with the Caesar Cipher algorithm and the Stout Sodes algorithm. The test results show that the use of the Caesar Cipher and Stout Codes crypto-compression systems can increase the security of the MySQL database system by making access difficult for unauthorized parties with a success percentage of 100%. Thus, it is hoped that this research can contribute to improving the security of the MySQL database system which is currently increasingly vulnerable to cyber attacks

Abstract

Dengue Hemorrhagic Fever (DHF) poses a serious threat to public health, caused by the Dengue virus transmitted through Aedes aegypti or Aedes albopictus mosquitoes. DHF can affect individuals of all age groups, especially children, with a mortality rate reaching 25% among children, as noted by the World Health Organization (WHO). Despite a decrease in DHF cases in 2020, the numbers remain high, presenting a significant issue in Indonesia, particularly in Kota Medan. RSUD Dr. PIRNGADI in Kota Medan is one of the hospitals addressing DHF cases. The primary challenge faced is the substantial increase in DHF patients in 2020, leading to a decrease in the effectiveness of patient care and an accumulation of administrative registration issues. Currently, there is no specific predictive system or research on DHF at RSUD Dr. PIRNGADI. This research aims to integrate the Naïve Bayes Algorithm and a website for early detection of DHF at RSUD Dr. PIRNGADI. Data on DHF symptoms are collected through patient medical records, and the Naïve Bayes Algorithm is employed to predict the likelihood of DHF. The detection system will be linked to an API and integrated into the RSUD Dr. PIRNGADI website, enabling users to conduct online DHF detection by entering patient symptoms. With this research, the goal is to contribute to enhancing the management of DHF cases at RSUD Dr. PIRNGADI, improving the efficiency of patient care, and providing a solution for the increasing number of DHF cases. The findings of this research can also serve as a foundation for developing similar systems in other hospitals and contribute to more effective efforts in preventing and controlling DHF

Abstract

Dengue fever is an infectious disease caused by the dengue virus and transmitted through the bites of Aedes aegepty and Aedes albopictus mosquitoes. Naive Bayes is a simple probabilistic classifier that calculates a set of probabilities by summing the frequency and combination of values from a given dataset. In this study, we will analyze dengue hemorrhagic fever disease data using the naive bayes method using 9 variables. This expert system application to diagnose dengue disease is made with a web-based application, so that it can be accessed by the public at large, besides that this application can also help medics to make decisions in diagnosing dengue disease. From the results of the study, the use of the Naïve Bayes method in this application is due to the results of the probability of the accuracy value of the Naïve Bayes method which is close to the accuracy of the experts. In this study, 3 experiments were conducted using 4 test data and the results showed that based on the three experiments, the accuracy value ranged from 96% to 97%, indicating that the classification accuracy had a small error value. So that classification using Naïve Bayes in this study can be applied to determine the classification of dengue hemorrhagic fever incidence.

Abstract

Stunting is a condition of inhibited linear growth due to chronic malnutrition, which is a serious concern in Indonesia, especially among toddlers. Stunting identification utilizes the parameter of height-for-age z-score (HAZ), with a value of less than -2 SD as a diagnostic indicator. Factors such as socioeconomic conditions, dietary patterns, infections, and the environment influence stunting, making early prevention and intervention efforts crucial. Short-term effects of stunting include delayed motor development and cognitive impairment, while long-term impacts include the risk of chronic diseases in adulthood. Although the global prevalence of stunting has declined, Indonesia still has a high rate, ranking second in Southeast Asia. Cross-sector collaboration and the application of technology, such as Support Vector Machine (SVM) algorithms, can help identify stunting risk factors. In this study, SVM kernels including linear, polynomial, RBF, and sigmoid were evaluated. RBF SVM kernel proved to be the most effective, achieving an accuracy of over 90% with an AUC of 0.926. Collaboration and the use of technology provide hope for addressing stunting in Indonesia, requiring cooperation between the government, NGOs, and the scientific community

Abstract

Bullying in the workplace not only has a negative impact on the individual who is the victim, but also has negative consequences for the organization and witnesses who witnessed the incident. The purpose of the study is to describe the psychological aspects related to bullying in the work environment using a valid theoretical conceptual framework. This study combines the Analytical Network Process (ANP) and Structural Equation Modeling (SEM) approaches to investigate the phenomenon of bullying in the work environment with a focus on the gender dimension. The findings suggest that gender has a significant role in influencing the experience of bullying in the workplace, with significant differences between individuals based on their gender. The integrative models of ANP and SEM successfully identified the complexity of the relationship between related variables such as the strength of interpersonal relationships, gender differences, and organizational policies, while also highlighting the negative impact of bullying on individual psychological well-being and organizational productivity. This study shows that all indicators of bullying behavior in the workplace have a p > value of 0.3 based on the results of confirmatory factor analysis. These indicators are threats to professional status (0.591), threats to individuals (0.538), isolating (0.399), excessive workload (0.649), and acts that cause instability (0.310). These results indicate that each of these factors is significant and relevant in measuring bullying behavior in the work environment.
