Yahya Muhaimin Sinaga — 2025-02-20

The development of information technology today is a necessity that must be mastered by every individual or organization to increase effectiveness and efficiency in a field, especially in business. There is a use of information technology to support a very diverse business, one of which is the use of electronic commerce or what is commonly called electronic commerce. Toko Usaha Patrah is a shop that sells household appliances. So far, the sales processing system has been less than optimal, and it is difficult to reach customers. Based on these problems, Usaha Patrah requires a good online sales business process to support the smooth running of the business. So the implementation of a web-based e-commerce application to expand its business and be known to many people.

Analysis of Trends and Profitability Growth Opportunities of the VTuber Industry Using Exploratory Data Analysis (EDA) Methodology

Ananda Aulia — 2025-03-17

The VTuber industry has experienced significant growth in recent years, with VTubers as virtual influencers engaging with global audiences through live streaming and content creation. However, the financial performance of this industry remains underexplored. By applying EDA, this research investigates the key factors influencing the profitability of VTubers, including audience engagement, monetization strategies, and content diversity. The analysis is conducted using data collected from various VTuber channels, including viewer statistics, revenue streams (such as Super Chats, merchandise, and sponsorships), and social media metrics.

The EDA methodology proves to be effective in providing valuable insights into patterns and relationships between variables affecting profitability in this industry. Through data visualization and descriptive statistical analysis, EDA identifies factors contributing to VTuber performance, such as audience interaction levels and monetization success. The findings demonstrate that EDA offers a clear overview of trends and growth opportunities within the VTuber industry, helping content creators, investors, and industry stakeholders make more strategic, data-driven decisions.

ANALYSIS OF HEART FAILURE PREDICTION WITH RANDOM FOREST ALGORITHM AND LINEAR REGRESSION

Ismar Hidayat — 2025-03-03

Predicting the risk of heart failure is an important step in the prevention and early treatment of potentially fatal cardiovascular diseases. This study aims to compare the performance of two machine learning algorithms, namely Random Forest and Linear Regression, in predicting heart failure based on patient data that includes variables such as age, blood pressure, cholesterol levels, and other health history. The results show that the Random Forest algorithm is significantly superior in terms of prediction accuracy compared to Linear Regression, especially on data with a pattern of the number of data used. However, Linear Regression remains relevant in providing more stable results on differences in the amount of data used and has a more significant effect on the variables of heart failure. Therefore, a Random Forest-based prediction model is recommended to predict heart failure if it has a large amount of tranning data, and Linear Regression is recommended for prediction stability. The implementation of this model is expected to help medical practitioners in making more appropriate and accurate decisions to prevent the occurrence of heart failure in high-risk patients.

ANALYSIS OF THE SALES POTENTIAL OF BUMDES PRODUCTS USING THE K-MEANS CLUSTERING ALGORITHM

Arifin — 2025-03-03

This research aims to measure the strategy and potential of Village-Owned Enterprises (BUMDes) in Tandam Hulu II Village using Business Intelligence (BI) Tools supported by the K-Means Clustering method. BI Tools is used to analyze the performance and potential of BUMDes, while K-Means Clustering groups community data based on economic, social, and demographic characteristics. The results of the study show that BI Tools helps BUMDes accurately map the economic potential of villages and develop appropriate development strategies. Clustering analysis allows the identification of community groups with similar characteristics, so that BUMDes programs can be tailored to the specific needs of each cluster. This implementation also improves operational efficiency by focusing resources on high-potential sectors. In conclusion, the implementation of BI Tools and K-Means Clustering supports data-based decision-making in BUMDes, maximizes the economic potential of villages, and encourages sustainable economic growth.
