Abstract

Accuracy in choosing a location is one of the factors that determine the success of a business. Entrepreneurs always have a location close to customers in order to provide primary service to customers so that relationships can be maintained properly. The right business location is expected to meet consumer expectations in order to obtain profit, but if there is an error in choosing a business location automatically the maximum profit will not be obtained by the entrepreneur. The purpose of this research was to determine the effect of choosing a business location on sales. The selection of sales locations is very influential on the sales results of traders. Place/location of business is one element of the marketing mix which is very important for the continuity of a business. This type of research includes field research, namely the new market clothing store and the old market in the Rantauprapat. This research is descriptive, because this study seeks to collect existing facts. This research focuses on efforts to reveal a problem and the situation as it is, which is examined is the technique of interviewing and documentation. While the data analysis was carried out using the data obtained in the form of descriptions, then the data were analyzed using inductive thinking. The results of the research indicate that there is a very strong relationship between the place of business and the profit. The place of business has a positive effect on the profits obtained by the trader.

Abstract

The progress of a food and beverage product business can be noticed through its advertisements because by advertising its products, people will recognize it. Brand image also supports the success of a business, because a brand that is known to the wider community will influence consumer desires. Lastly is product design, where the form of packaging also influences consumer tastes from AGADES.ID, especially ZOZU products. Based on the results of the analysis and discussion that has been carried out, it can be concluded that the partial hypothesis testing shows that the advertising variable has a positive and significant effect on the consumer’s taste variable, the brand image variable has a positive and significant effect on the consumer's taste variable and the product design variable has a positive and significant effect on variable consumer tastes. This result means that the variable consumer taste can be influenced by advertising, brand image, and product design variables by 30.4%, while the remaining 69.6% is influenced by other factors not discussed in this study, such as discipline, motivation, and so forth.

Abstract

This study develops an IHSG stock price forecasting model using a hybrid CNN–BiGRU architecture enhanced by an attention mechanism. The key novelty lies in combining CNN-based local pattern extraction with BiGRU-based bidirectional temporal modeling, while attention selectively emphasizes the most informative time steps, improving representation quality for complex and noisy financial series. Historical IHSG data from public sources were preprocessed through feature engineering and normalization, followed by XGBoost-based feature selection to retain the most predictive variables. Model robustness was assessed in two settings: (i) the full dataset and (ii) a “cleaned” dataset excluding the extreme COVID-19 volatility period. The proposed model achieved strong accuracy, with MAE/RMSE of 0.0125/0.02 on the full dataset and 0.0167/0.03 on the cleaned dataset, while Pearson correlation remained close to 1 in both scenarios, indicating high alignment with actual IHSG movements. A 30-day ahead forecast produced a stable and realistic trend. Overall, the CNN–BiGRU with attention provides an effective and robust approach for capturing multi-scale temporal patterns in IHSG forecasting.

Abstract

This study aims to analyze the comparative performance of three machine learning models Neural Network, Random Forest, and XGBoost in predicting the stock price of Bank Rakyat Indonesia (BBRI.JK) based on feature engineering integration. The background of this study is based on the need to develop accurate and efficient predictive models to deal with stock market volatility. The Data used covers the period 2010-2025 with the application of technical indicators such as Moving Average (MA), Relative Strength Index (RSI), volatility, and price momentum as the main features. The research method uses a machine learning approach based on supervised learning with a five-fold cross validation process. Model evaluation was conducted using quantitative metrics including Mean Absolute Error (MAE), Mean Squared Error (MSE), Root Mean Squared Error (RMSE), coefficient of determination (R2), and Mean Absolute Percentage Error (MAPE). The results showed that XGBoost produced the Best Performance With R2 = 0.9451, MAE = 87.3129,and MSE = 10327.1187, followed by Random Forest (R2 = 0.9233) and Neural Network (R2 = 0.9120). The XGBoost Model proved to be the most stable and efficient in handling nonlinear data as well as extreme price fluctuations. The discussion confirms that the integration of engineering features improves the generalization capability of the model and lowers the prediction error rate significantly. Future research is recommended to include macroeconomic variables, sentiment data, and reinforcement learning approaches to broaden the scope and improve the model's adaptability to global financial market dynamics.
