<![CDATA[The development of data technology and its utilization is very fast, resulting in humans’ competition for innovation in the data that can be more easily processed in such a way as to meet user’s expectations. Data integration is an important aspect to make data and information are connected one and another. Weaknesses that often arise from the traditional-way of ETL (Extract-Transform-Load) are the complexity of connections from multiple sources, as well as the dependence on temporary data storage to allow data to flow from the source Database to the target Database. The application of data virtualization can provide the right solution to integrate data more effectively and more efficiently than the use of ETL methods in general. The purpose of this research is that Data Virtualization can provide features and renewable technology, making it easier for users to generate daily or monthly bank reports faster in accordance with the expectations and provisions in the Bank Indonesia (BI) regulations. Therefore, in the process of this research, R&D (Research and Development) is still considered the most appropriate method. The results of this research are solutions or commercial bank’s data processing systems that can issue the result information that will be daily / monthly reported by the users to Bank Indonesia.]]>

<![CDATA[Heart disease is one of dangerous diseases. The late treatment for the disease will endanger the life of the sufferers. This problem is caused by the difficulty of early detection in patients with heart disease because they always ignore the initial symptoms. In addition, the costs involved in examining heart disease are not cheap because it requires examinations carried out by specialists and laboratory tests. The prediction system is one of options that can be used to perform early detection of heart disease patients at a lower cost, with the costs used in examinations by specialist doctors and laboratory tests can be eliminated and replaced by a prediction system. This study aims to create a prediction system using the C4.5 algorithm by which the predictions based on historical data of the patient to be examined are made. The results obtained from using the C4.5 algorithm to make predictions show an accuracy of 79%, meaning that the results can be expected to be a source of information for further research on prediction systems using the C4.5 algorithm.]]>

<![CDATA[Product inventory in retail companies is crucial because a product is a major component in the business and is a thing that is traded to meet the needs of consumers. In business, entrepreneurs certainly expect optimal profits that can be achieved by increasing the value of product sales. As a supporting factor in the success of a business, stock of products must always be available to meet the needs of consumers. The problems that often occur in retail companies are a product stock shortage and product stock buildup that can result in the damage of products because of being kept in the warehouse for a long time and can hinder the capital mobility. A product stock prediction system is needed to reduce the problems and can predict the amount of product stock in the future so that product availability can be controlled and the company can achieve the expected goals. This paper aims to provide a web-based product stock prediction system with a Single Exponential Smoothing and Moving Average method to determine the amount of product stock that must be available in the future. The comparison results of the two methods implemented in the prediction system show the Single Exponential Smoothing method with an alpha value of 0.5, superior to the Moving Average method with the results of the prediction error accuracy value in the Aqua 19 L product, namely MAD = -0.50, MSE = 3.02 and MAPE =11.38.]]>

<![CDATA[BJB Syariah has several work units, including branch heads, operational managers, back offices, tellers, customer service and marketing. In recording the submission of financing customers, BJB Syariah still performs the documentation using paper media so that the knowledge obtained is still difficult to process. It makes the customer data lost or not neatly arranged, leading to a relatively long period of searching the data. Therefore, it is necessary to have a system that can provide convenience in recording customer submissions in the form of a Knowledge Management System. The system is expected to produce information that is related to customers and can be documented as evidence of data storage in real time. The system development method used is Rapid Application Development (RAD) starting from the Requirement Planning stage to the Workshop Design stage. The design tool used is the Unified Modeling Language (UML). The system is made using software Preprocessor Home Page (PHP) as a programming language and MySQL as database management. The designing of this web-based knowledge management system produces reports containing customer data and reports on financing submission on a regular basis.]]>
