This research aims to develop and evaluate Instagram content based on the 4C model (Context, Communication, Collaboration, Connection) in increasing customer engagement on the Feraluna Boutique Instagram account. The main problem identified is the low engagement rate indicated by the minimal number of interactions on previously published Instagram content. This research uses the Research and Development (R&D) method with the ADDIE model approach (Analysis, Design, Development, Implementation, Evaluation). The data collection process was carried out through observation, documentation, and distributing questionnaires to 94 followers of the @feraluna_boutique Instagram account and expert assessment. The results showed that the application of the 4C model-based content strategy was able to increase impressions by 400.96%, account reach by 518.7%, and interaction by 1900%. Thus, the developed content proved effective in significantly increasing customer engagement. This research provides theoretical contributions to digital marketing literature as well as practical contributions for businesses, especially in the local fashion industry, to optimize the use of social media as an effective promotional tool.

This research aims to determine the level of user satisfaction with the user interface and user experience of the Shopee Application by classifying it using the C.4.5 algorithm. The research subjects used in this study are students of the Digital Business Study Program at Universitas Negeri Medan. This research uses a descriptive quantitative approach, with data collection through questionnaires designed using a Likert scale. The data obtained will then be analyzed using the C4.5 algorithm to produce a decision tree consisting of eight attributes used, namely strive for consistency, usability, offer information feedback, design dialogs to yield closure, prevent errors, permit easy reversal of action, keep user in control, and reduce short-term memory load. The result of the decision tree will form a rule or pattern that is easier to understand. From the data that has been collected, this research shows that the majority of user satisfaction levels fall under the class label category "SATISFIED," with the data divided into three classes: very satisfied, satisfied, and dissatisfied. In this study, the C4.5 algorithm was very capable of building a good classification model with an accuracy rate of 95%. This shows that the model is capable of classifying user satisfaction data very well.

This study aims to develop and evaluate an Expert Advisor (EA) based on the Donchian Channel indicator combined with the Safe-F Money Management strategy for trading the XAG/USD pair using the MetaTrader 5 platform. The EA is designed to capture breakout opportunities while adaptively managing trade size based on account balance. Testing was conducted using two approaches: backtesting with four years of historical data and real-time testing under actual market conditions. The backtesting results indicate that the H1 time frame scenario yielded more stable performance, with a Sharpe Ratio of 1.26 and low drawdown. In contrast, the real-time testing recorded less optimal outcomes, with profit factors below 1 and net losses in both scenarios. These findings suggest that although the EA performs well in simulations, real-time performance is affected by market volatility and execution factors. Therefore, further optimization and broader testing are recommended to enhance the system’s resilience in dynamic market environments.
