Decision Support System in Determining Employee Loan Eligibility Using AHP-TOPSIS at PT XYZ

Febriani Sulistiyaningsih — 2025-01-04

A decision support system is a system used by top level managers in making decisions. The decision support system has several methods that can be used, including the AHP and TOPSIS methods. The AHP (Analytical Hierarchy Process) method is a decision making method that focuses more on calculating criteria weights. Meanwhile, the TOPSIS method (Technique for Order of Preference by Similarity to Ideal Solution) is a decision-making method that is suitable for calculating final results and rankings. Determining employee loan eligibility using the AHP and TOPSIS methods produces objective values because the criteria weights and final results are calculated according to the method used.

Liga Mayola — 2025-01-04

Hospitals play a vital role in providing healthcare services to the community. Every day, patients visit hospitals to receive medical care. Over time, patient visit data continues to grow, resulting in a massive accumulation of data. This large volume of patient visit data can be clustered using data mining algorithms, providing strategic insights for resource management, facility planning, and improving the quality of healthcare services. The purpose of this study is to classify hospitals based on the number of patient visits over the past five years. The clustering process was conducted using the K-Means Clustering Algorithm. The research data was obtained from the Satu Data Sumbar website. Hospital patient visit data was grouped into three clusters. The results indicate that Cluster 1 (K1) represents hospitals with very high visit intensity, Cluster 2 (K2) represents hospitals with medium visit levels, and Cluster 3 (K3) represents hospitals with low visit levels.

The property sector plays a vital role in the global economy, especially regarding property price prediction, which is a complex challenge influenced by factors such as building size, number of rooms, location, and property condition. This study aims to build a property price prediction model using the Linear Regression algorithm. The data used in this research was obtained from Kaggle, consisting of 1460 data points on house prices in Ames, USA. The preprocessing phase includes handling missing data, outlier management, and feature standardization using StandardScaler to ensure data consistency. The linear regression model was trained and evaluated using R-squared (R²) and Root Mean Squared Error (RMSE) metrics. The evaluation results show an R² of 0.81, indicating the model explains 81% of the variation in house prices. Additionally, the RMSE value of 35,830.40 shows the model's relatively low and consistent error when tested with different data. Features such as overall house quality (OverallQual) and living area size (GrLivArea) significantly correlate with house prices. These findings demonstrate that linear regression is an effective tool for predicting property prices.

As digital payments in Indonesia increase, they drive the financial industry, especially banking, to continue their digital transformation. BANK XYZ is one of the banks that is also undergoing digital transformation. To improve banking services that are always available and meet market demand, it is necessary to fulfill the demand for information technology (IT) services. However, there is a problem in this process, namely that many requests are not followed up and closed even though they have been worked on, causing delays in fulfilling user requests. Therefore, this research aims to evaluate the process of fulfilling IT service requests and provide improvement recommendations for the future. The evaluation process in this study uses the COBIT 2019 framework to measure the capability of relevant process areas, and ITIL V4 provides good practices for process improvement recommendations. After data collection and capability measurement on eleven processes, the results showed that three processes were at level two, namely APO09, BAI08, and BAI10. There are five processes at level three, namely BAI07, BAI08, DSS02, DSS03, and DSS04. For the achievement of level four, there are two processes, namely APO14 and BAI06, and one process that has reached the level, namely DSS01. Then, in the gap analysis process, there are three processes that have met the management's targets, namely APO14, BAI06, and DSS01, and eight processes that have not yet met the targets. Recommendations are given for the eight processes that have not yet met the management's expected targets.

A Novel RGB-Depth Imaging Technique for Food Volume Estimation

Yuita Arum Sari — 2025-01-16

Evaluating nutrient intake among patients in a hospital is crucial, as it can accelerate their recovery process. Estimating calorie intake can be achieved by monitoring the quantity of food consumed by patients both before and after their meals. This approach involves various methods, including the use of digital scales, the Comstock level, and digital imaging techniques. Nonetheless, these techniques have their own limitations, particularly the risk of subjective assessments. To reduce errors arising from human factors, an objective evaluation is proposed. This paper introduces a new technique for measuring volume using RGB-Depth images. The method incorporates image segmentation and edge detection in RGB images to correspond with the depth image. Subsequently, the segmented regions and boundaries from the depth images are converted into point clouds. The volume of interest is calculated by fitting the point cloud to an ellipsoid. The lowest Mean Average Percentage Error (MAPE) is 2.73. It indicates that the proposed method is sufficient to measure the food volume.
