Abstract

The purpose of this study is to analyze car purchase decisions using the Multi-Objective Optimization based on Ratio Analysis (MOORA) method. This method was chosen because it is able to handle various conflicting decision-making criteria. The study evaluated fifteen car alternatives based on seven criteria: price, fuel consumption, engine capacity, safety features, comfort, resale value, and CO2 emissions. Price and CO2 emission criteria were considered the most important, while other criteria were considered the most important. The analysis process begins with data collection and the application of criteria for value normalization for each alternative. Then, the final score is obtained by summing the normalization value of the maximized criteria and subtracting the normalization value of the minimized criteria. The results of the analysis show that the car that receives the highest score is the most suitable to buy. This research shows how the MOORA method functions in decision support systems and provides useful knowledge to consumers on how to make more informational and data-driven purchasing decisions.

Abstract

Stress is a mental disorder that is commonly experienced by employees of PT ACE HARDWARE INDONESIA Tbk. Most of the stress that occurs is often considered trivial, and if the stress is not handled immediately it will get worse and will affect productivity at work which will cause a decrease in turnover for PT ACE HARDWARE INDONESIA Tbk. So therefore we need a tool or system that has the ability like a psychologist in diagnosing this level of stress. The system is an expert system that solves problems as is usually done by experts. This study aims to create an expert system application for stress diagnosis. This system application diagnoses stress levels with the Prototype and the Certainty Factor method. The Certainty Factor method is a method for proving whether a fact is certain or uncertain. This method provides space for experts to give confidence in the knowledge they have. From calculations using the Centainty Factor method at each level, from the symptoms that employees input for mild stress levels the probability is 0.92% or 92%, while the symptoms inputted by employees for moderate stress levels are likely to be 0.994624 or 99.46%, from the results of the comparison of these possibilities the maximum value of CF is 0.994624 or 99.46% with a moderate stress level.

Abstract

Human resources are productive individuals who work as drivers of an organization needed for operational activities in it. PT. Citra Baru Perkasa is a private company that manages human resources, so it is not uncommon for problems to occur in its management, in this case to assess employees who receive promotions at PT. Citra Baru Perkasa which is carried out every 1 year, there are several problems that occur in the process of assessing and selecting employees receiving promotions, namely when the assessment process of promoted employees carried out by managers still uses questionnaire paper and in the process of calculating the assessment is only determined from the average value on each criterion, this makes the calculation look inaccurate and less accurate. Based on the existing problems, a solution was obtained by building a decision support system using two methods, namely Simple Additive Weighting (SAW) and Weighted Product (WP), The purpose of building this system is to help reduce errors and simplify the assessment process. The results of this study showed that one of the employees of PT. Citra Baru Perkasa is eligible for promotion. This is based on the calculation results using both methods, namely an employee named Kurniasari who has a value of 1 using the SAW method and 0.210 with the WP method.

Abstract

This study compares the effectiveness of the Random Forest and Decision Tree algorithms in predicting students' academic performance based on learning activities. The data used included reading scores, writing scores, math scores, and demographic variables such as gender, race/ethnicity, parental level of education, lunch, and test preparation course. The research was carried out through the stages of data cleaning, training and test data sharing, model training, and evaluation using confusion matrix and accuracy, precision, recall, and F1-score metrics. The results show that Random Forest performs best with 97% accuracy, surpassing Decision Tree which has 94% accuracy. The feature importance analysis  revealed that cognitive ability—especially in the reading score, writing score, and math score features—had the greatest influence on prediction results. These findings confirm that the Random Forest model is more reliable and effective as a prediction tool in the academic decision support system to detect the potential for decline in student achievement early.
