We Are Social 2023 states that 167 million Indonesians are active in using social media. In general, flexing is done to legitimize social status through various uploads on TikTok, Instagram Facebook, YouTube and others. This study aims to analyze of the influence of flexing in social media on community life. The results of the study show that luxury content is a favorite of netizens. Even though the luxury that is displayed is not necessarily true. Flexing has a positive influence because flexing can be used for employee branding through linkedIn. Flexing marketing to achieve success in popularity, business and endorsement. However, overall flexing has a more negative influence . Flexing creates consumptive behavior and hedonism. The use of goods is no longer interpreted as fulfilling needs, but rather as a brand or symbol to indicate lifestyle and social status. Sometimes flexing is used as a method of deception. POLRI and related institutions are expected to be more informative, actively monitoring and countering flexing content that has the potential to harm the public. Intelligence is needed in managing information, in the era of information openness, people must be more proficient in social media, filter flexing content so they don't get trapped in FOMO. Actually, flexing is the right of each individual, but it should not reduce the values of life. Minimize flexing behavior by prioritizing achievement.

Abstract

Alzheimer’s disease is one of the most common forms of progressive dementia and has become a major global health challenge as the aging population continues to increase. Early detection of this disease is crucial to mitigate its social, economic, and health impacts. In this context, data-driven approaches using machine learning algorithms can be utilized to predict Alzheimer’s risk more accurately. This study aims to compare the performance of three ensemble learning algorithms—Gradient Boosting, Random Forest, and AdaBoost—in predicting the risk level of Alzheimer’s disease using the public Alzheimer’s Disease Dataset, which includes demographic, clinical, and lifestyle data. The research process involved several stages, including data preprocessing, splitting data into training and testing sets, model training using cross-validation, and performance evaluation based on accuracy, precision, recall, F1-score, and AUC metrics. The experimental results show that the Gradient Boosting algorithm achieved the best performance with an accuracy of 0.956, an F1-score of 0.956, and an AUC of 0.985, demonstrating its ability to capture complex non-linear relationships among features such as age, MMSE score, and lifestyle factors. Meanwhile, Random Forest and AdaBoost achieved competitive yet slightly lower performance. These findings indicate that ensemble boosting approaches, particularly Gradient Boosting, hold great potential for medical decision-support systems in the early detection of Alzheimer’s disease and can serve as a foundation for developing more accurate and adaptive predictive models in the future.

Abstract

Gold is one of the most popular investment instruments due to its stable value and ability to protect assets against inflation. However, its price tends to fluctuate significantly, influenced by macroeconomic factors such as exchange rates, interest rates, and global geopolitical conditions. This study aims to analyze the movement patterns and predict gold prices based on historical data from 2019 to 2024 using the Linear Regression method and Time Series models, namely ARIMA and VAR. The analysis process was carried out using Orange Data Mining software, which enables the application of machine learning algorithms through a visual and interactive interface without manual coding. The dataset used consists of daily gold closing prices, processed and tested to evaluate model accuracy using Root Mean Square Error (RMSE) and Correlation Coefficient (R) indicators. The results indicate that the Linear Regression model effectively captures the general trend of gold prices, while ARIMA and VAR models produce more accurate forecasts based on historical fluctuations. The integration of regression and time series approaches improves prediction reliability. Overall, this research contributes to the development of financial data analysis and provides insights for investors in making more informed and data-driven investment decisions.
