<![CDATA[Information System is an organizational component that collects, classifies, processes, analyzes and communicates relevant financial information for decision making to external parties (such as tax inspections, investors and creditors) and internal parties (especially management). This information system is also expected to reduce errors that occur, especially the accounting information system regarding the processing of fixed assets when producing financial information in accordance with accounting standards. Meanwhile at PT. Coca Cola is currently not using a computerized system to cover current weaknesses such as calculating the depreciation of fixed assets at PT. The Coca-Cola. For this reason, it is necessary to make an application using the Microsoft Visual Basic programming language and the Microsoft SQL Server database where it is hoped that the application will be designed to cover the current weaknesses. Where is the program made regarding the processing of fixed assets so that it can cover any weaknesses in the old system.]]>

<![CDATA[Value is an important thing in the world of education and requires a special processing and policy, both in its use, maintenance and recording. Because of the importance of using this value, it is necessary to carry out systematic and effective processing of the values obtained by students. Processing grades consisting of formative grades, assignment grades, and semester grades for each student. To calculate the student's grades, the K-Means method was used to determine students who excel at SMA Swa Bina Karya. The information system for determining outstanding students at Swa Bina Karya High School is still manual. Where the process of recording and calculating student grades is still manual where the recording of each student's grades is recorded in the gradebook owned by each homeroom teacher so that the process of making class ranking reports requires a lot of time and the resulting information is less effective and efficient. To be able to overcome this frequent problem, the authors designed a system for determining student achievement using the K-Means method using Microsoft Visual Basic.Net 2008 and the database used was Sql Server 2008. With the design of this system, the homeroom teacher and school principal can receive more accurate and timely class ranking reports. Besides that, this system also helps admin work much more effectively and efficiently]]>

<![CDATA[Depreciation is the allocation of the acquisition price of fixed assets into expenses into the accounting period that enjoys the benefits of these fixed assets, there are three factors that need to be considered in determining the depreciation expense for each period, namely the acquisition price is the entire amount of money spent to acquire an asset used by the company, residual value is the estimated selling price of the fixed assets at the end of the useful life of the fixed assets, the amount of the estimated residual value will also be greatly influenced by its economic age, inflation, currency exchange rates, line of business and so on. The estimated useful life is the estimated useful life of the fixed assets. The useful life is the estimated economic life of the fixed assets, not the technical life. The estimated useful life can be expressed in units of a year's period. Therefore the application is made using the Visual Basic programming language. Net 2010 and SQL Server 2008 as the database. With the existing tools in the calculation of depreciation of fixed assets, it can assist companies in making depreciation reports that exist in these companies]]>

<![CDATA[In an era of increasingly complex business competition, selecting the best employees has become crucial to ensure organizational productivity and success. In this endeavor, the integration of Multi-Criteria Decision Analysis Method with emphasis on Analytical Hierarchy Process (AHP) has emerged as an objective and scientific approach. This research discusses how the AHP method can be applied in the context of best employee selection by analyzing relevant criteria and pairwise comparisons that are calculated to generate relative weights. Through this process, best employee selection decisions can be made on a stronger and more transparent basis. However, the success of this method depends on the quality of the data and the assumptions used in the calculations. Although complex, AHP can provide valuable insights for decision makers in finding a balance between diverse criteria in the process of selecting the best employee.]]>

<![CDATA[In the context of a challenging retail business, optimizing inventory ordering decisions is crucial to maintain product availability and avoid excessive storage costs. Decision Support System (DSS) approach with the application of exponential smoothing method has emerged as an effective solution to integrate data analysis and more precise decision making. This abstract discusses how exponential smoothing is used in optimizing inventory ordering decisions in retail businesses. We explain the concept of exponential smoothing as a forecasting technique that integrates historical data and future predictions. We also analyze the steps of implementing exponential smoothing in DSS, including smoothing parameters, initialization of initial levels, and forecast calculation. The benefits and challenges in the use of exponential smoothing are discussed in the context of inventory optimization and ordering decision making. The results show that exponential smoothing can provide forecasts that are more adaptive and responsive to changes in demand, with the potential to improve operational efficiency and customer satisfaction. Nonetheless, an understanding of the product characteristics and limitations of the method needs to be considered. This research illustrates how the use of exponential smoothing in DSS can provide valuable guidance for retailers in optimizing inventory and making inventory decisions.]]>
