Abstract

Business development is getting faster and full of rivals, especially in the world of MSMEs. MSME entrepreneurs need to develop marketing strategies so that their products can sell a lot so that they can make a profit. One way to assist in marketing strategies can use a priori algorithms so that they can help in sales patterns by using historical consumer transaction data. After testing the results of this system gives good results. This a priori algorithm has several stages in the calculation process starting from the process of calculating support and determining minimum support to evaluate data values that are below minimum support. Then the confident calculation to assist in the formation of association rules so that there are steps to evaluate the value of data that is below the minimum confident. Then there is an elevator to provide information validly and show the transaction process. The results obtained from this a priori algorithm form an association rule "If you buy a cassava balado stick, then buy a balado corn stick" then from this association rule entrepreneurs can be helped in selling products that tend to be bought by many consumers. The last stage is tested from manual calculations ranging from support, confident to elevator with calculations on the web. The test results obtained that manual calculations and calculations on the web have the same value.

Abstract

This research aims to improve the accuracy of stock price prediction through the application of Long Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU) methods, focusing on stocks from the Composite Stock Price Index (CSPI) referred to as the IDX Composite. The research process includes comprehensive steps, including data collection and preprocessing, dataset creation with emphasis on stock closing prices, and division of the dataset into training and test data. The LSTM and GRU models were designed with a recurrent layer and a Dense layer and then trained for 100 epochs with a batch size of 32. Model evaluation was performed by comparing key metrics such as Root Mean Squared Error (RMSE), Mean Squared Error (MSE), and Mean Absolute Error (MAE) on the test set. The EPOCH-RMSE graph provides an overview of the changes in the RMSE value during training. The best result of the LSTM model was achieved at the 96th epoch with RMSE 40.36, MSE 1385.97, and MAE 30.09, while GRU achieved peak performance at the 92nd epoch with RMSE 37.33, MSE 908.29, and MAE 25.42. In conclusion, GRU can be considered as a more effective option in predicting JCI stock prices based on performance evaluation using various metrics such as RMSE, MSE, and MAE.

Abstract

The development of information technology (IT) has brought significant changes in various industries, including the health sector. This research focuses on architectural business planning at the Soemitro Air Force Hospital using the TOGAF ADM 9.2 approach. Even though this hospital has implemented an Electronic Medical Record (E-MR) system, various problems such as poor integration, data duplication, and input errors still hamper operational performance. The aim of this research is to develop a comprehensive architectural business to improve operational efficiency and quality of hospital services. This study begins with an evaluation of the hospital's business and strategic needs, followed by careful planning in accordance with the IS/IT strategy. The use of the TOGAF ADM framework was chosen because of its flexibility and opensource nature, which facilitates the development of an optimal organizational architecture. It is hoped that the research results will provide guidance for hospitals in integrating information technology with their business processes, increasing productivity and improving the quality of health services. Thus, this research not only contributes to information technology management in the health sector but also enriches understanding of the effective and efficient implementation of architecture vision in the hospital context. Implementing a proper IS/IT strategy is expected to align hospital IT needs with business process demands, reduce errors and data duplication, and increase patient satisfaction. This research underlines the importance of strategic planning in information vision development to achieve long-term organizational success.

Abstract

I In an effort to improve health services, Surabaya City Health Service provides an innovation through the implementation of the E-Health system. E-Health is an information technology development that aims to provide a service system in the form of an online queue for patients at Surabaya health centers and hospitals. Based on the findings that have been made, there are several complaints about E-Health, which can impact the level of patient satisfaction with their experience using E-Health services. E-Health is part of an online-based service system, so the E-Servqual method is used. Additionally, the IPA approach used in this research identified the key attributes that need improvement to maximize user satisfaction and display priorities for improvement, allowing for a clearer view of which areas require immediate attention and action to improve the overall quality of E-Health services. The results of the research show that all dimensions still have measurable negative gap values, indicating specific areas where service quality does not meet user expectations. Specifically, the quality of service is rated at 0.86, which is less than 1, signifying that there are still aspects of the E-Health service that need enhancement. The attributes included in Quadrant I priority improvements on the Cartesian Importance Performance Analysis diagram are E4, E3, C4, P1, and RE4. Therefore, it is necessary to immediately address these main priorities so that E-Health services can be optimized and more satisfactory for users.
