<![CDATA[The Kelindang Bengkulu Tengah Village Office is one of the villages located in Merigi Kelindang District, Central Bengkulu Regency. So far, the data management process for Village-Owned Enterprises (BUMDes) has used office application packages, namely Microsoft Word and Microsoft Excel. However, not all administrative data processing processes use office application packages, one of which is the 3kg LPG base distribution administration. The Bumdes administration data application at the Kelindang Bengkulu Tengah Village Office is used to make it easier for the village office to process BUMDES administration data, especially regarding the supply and distribution of 3kg LPG Gas to residents within the scope of the Village of Kelindang Bengkulu Tengah. In the data processing process, a network-based two-tier architecture with a WLAN connection has been implemented, to simplify and speed up data input, because many laptops connected to the WLAN can access it. The devices used are 3 units of laptops, namely 1 laptop for the server and 2 laptops for the client. The Bumdes administrative data application at the Kelindang Village Office in Bengkulu Tengah was made using the Visual Basic .Net programming language and SQL Server 2008r2 Database. Based on the tests that have been carried out, the functionality of the Bumdes administrative data application at the Kelindang Village Office in Central Bengkulu is running well and as expected]]>

<![CDATA[SMA Negeri 6 Seluma is one of the state senior high schools in Seluma Regency. At the school, students are assessed every academic year through several criteria to select outstanding students who have the ability to master subjects and have good personal ethics. So far, the process of selecting outstanding students is only seen from the results of the report cards obtained by students, then ranking is carried out. This is of course less effective in determining outstanding students, because it must be supported by other aspects such as student ethics during the teaching and learning process. The recommendation application for selecting outstanding students at SMA Negeri 06 Seluma was made using the Visual Basic .Net programming language and SQL Server 2008r2 Database. This application has implemented one of the fuzzy logic methods, namely Fuzzy Tsukamoto which is used to help provide recommendations for selecting outstanding students at SMA Negeri 06 Seluma. The process of selecting outstanding students is carried out every academic year based on aspects based on aspects of average knowledge value, average skills score, absenteeism score, academic achievement, non-academic achievement, and guidance and counseling records. Based on the blackbox testing that has been done, the results show that the functionality of the recommendation application for selecting outstanding students at SMA Negeri 06 Seluma runs well as expected and is able to analyze student assessment data through the Fuzzy Tsukamoto Method to get recommendations for outstanding students]]>

<![CDATA[Sinar Baru Makmur In determining the extension of an employee's contract, it is taken from the results of an employee's performance appraisal, if the performance results are good or very good, a contract extension will be carried out. However, in determining the results of employee contract extensions there are still some subjective judgments, and family relationships that create gaps with other employees in determining the final outcome of the assessment. To avoid subjectivity in evaluating employee performance, this study created an application for evaluating employees by classifying them using the Naive Bayes method. Employee status classification application at PT. Sinar Baru Makmur is created using the Visual Basic .Net programming language. The application can help manage employee performance appraisal evaluation data and can also help provide recommendations for the eligibility of employee status whether to be extended or not renewed based on the classification results of the Naive Bayes Method.]]>
