<![CDATA[PT XYZ is a company engaged in car loans. This company sells various kinds of cars with credit payment systems. To ensure that the provision of credit is not bad, there are several criteria that are made by the company in accordance with the criteria that have been set. There are 4 criteria that are used as standards that must be met for consumers so that the car purchase system on credit is accepted. The 4 criteria include the capacity to pay off credit (Capacity), the ability of the customer's capital (Capital), the guarantee owned by the customer to bear credit risk (Collateral) and the customer's financial condition (Condition). The problem in this research is that there are often bad credit consumers who do not pay installments in accordance with the specified time. The purpose of this research is to help companies provide credit to consumers so that they are right on target. The settlement of this case uses Fuzzy Logic which is suitable to be implemented into a computerized system to take a decision. The method used in this study is the Sugeno method using the And operator and taking the MAX value. The final result of this study is in the acceptable range with a value of 196.33 . To see the other criteria, just input each x value into the existing system.]]>

<![CDATA[One area that has an important role in the business world is sales. There are different types of goods and services offered to the wider community and can be used to meet their needs. One example is the material of the building that is used as materials to build a house, building, school and other buildings. The building's material items are sold in the Building Store. However, most of the processing of data on the sale of building materials in the Building Store is still done conventionally, thus causing problems. Like, there were errors in data recording, data searches that took a long time, and the making of inaccurate sales reports. If this is allowed to happen, then the place of the venture could suffer a lot of losses and not be able to take the right steps to resolve the existing problem. Therefore, the place of the venture requires the construction of a system, especially for the sales information system. With the development of the system, it is hoped that we will solve existing problems and be able to monitor the performance of the system and evaluate it well. And in the development of the system, it has to be supported with the use of the right method, where one of the methods that can be used is MVC (Model View Cotroller). Using this MVC, we can see the data structure used, the view and also the list of programs for the creation of the program application. The sales program applications generated from the development of this system, of course, are very much expected to help improve the existing system and improve the service and generate accurate data]]>

<![CDATA[As a result of processing data in the form of documents too often, document files accumulate on storage media and make the storage media lack free space. One solution that can prevent this is data compression. In this study, we will try to analyze the performance of lossless algorithms, some of which are: Goldbach's Algorithm, Fibonacci's Algorithm, Rice Codes Algorithm, Additive Codes, and Yamamoto's Recursive Codes Algorithm. The main reason why a comparison is needed is to see which algorithm is the best, it is worth doing as a basis for making applications that can compress data because application users want the best results for them, and in this case, are those that can compress files and produce the smallest size compared to other algorithms. The data to be compressed is text data. The results obtained from the test are the Goldbach Codes and Fibonacci Codes algorithms are superior to the third algorithm and several times have the same results, namely compression ratios of 60% to 68% and space savings ranging from 32% to 40%.]]>

<![CDATA[Waroenk kids collage is a restaurant that sells various types of food menus and is located in Indonesia, Jakarta. This restaurant has data that accumulates and accumulates without any continuation of that data. This is not supported by the final report. Therefore, it is necessary to build a data warehouse that can be used as information for waroenk restaurant owners for college children. One of the important processes in the operation of the data warehouse is the process of copying data from the operational database. Before the data enters the data warehouse, the ETL (extract, transform, load) process is carried out on the data. This scheme is designed for the data warehouse at Waroenk Anak Kampusan using the Snowflake Schema model. The results of the research show that the Waroenk Anak Kampusan data warehouse has four tables (product table, price table, service table and customer dimensions), has one real table, namely the Sales table. All sales data can be monitored by the owner and can find out the total sales data.]]>

<![CDATA[Depth First Search Algorithm is a search process to find the right solution that requires short memory and time in finding the Goal. The problem in this research is the difficulty of salesmen to find alternative short routes to arrive at the final node as consideration for finding solutions. The purpose of this study is to find the shortest path so that salesmen can easily and quickly get to the final solution by saving time and mileage. The Generate And Test concept consists of combining the Depth first search algorithm with the backward tracking process. All processes must be completed before the testing process is carried out. If the General And Test process is carried out sequentially or systematically, it will get the best value in finding a solution, the weakness if the search process is large or extensive then the search process takes a very long time. How it works Generatr and test, namely 1. Generate possible solutions in the form of state states with the concept of a one-position path to the destination path. 2. Test, select whether the solution can be accepted according to the existing criteria 3. If the solution has got the Goal then the search is stopped, if not then the process is continued until finding a solution. The final result of testing the shortest route is A-B-E-J-P-S-U = 25+21+24+24+17+18=129]]>
