<![CDATA[Cataracts are a disease when the lens of the eye becomes cloudy and cloudy. In general, cataracts develop slowly and are not bothersome at first. However, over time, cataracts will interfere with vision and make the sufferer feel like seeing a foggy window, making it difficult to drive, read, and carry out daily activities. The expert system for diagnosing cataracts at Rafflesia Hospital Bengkulu was created to assist in diagnosing cataract patients by entering the symptoms experienced by the patient. In the process of diagnosing the expert system, a method has been applied as an inference engine that makes it easier to find out the results of the diagnosis, this method is Forward Chaining. Based on the results of the tests that have been carried out, the functionality of the expert system for diagnosing cataracts at Rafflesia Bengkulu Hospital has been running well as expected and can provide information on the results of consultations to determine cataracts.]]>

<![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[The document file security application at the Bengkulu City Education Office was made using the Visual Basic .Net programming language. In this application, 2 cryptographic algorithms have been implemented that can be used to secure document files, especially the employee payroll list file, namely the DES algorithm and the AES algorithm. In addition, this application has also embedded a process to analyze the comparison of the DES and AES algorithms, so that it can be known which algorithm is better to use. The comparison aspect consists of 2 aspects, namely processing time and file size after processing. Based on the tests that have been carried out, it can be concluded that the document file security application at the Bengkulu City Education Office is capable of carrying out the process of encrypting and decrypting document files and the functionality of the application has run as expected. From the test data that has been carried out by the encryption and decryption process, the results obtained based on the encryption processing time show that the AES algorithm is faster than the DES algorithm, based on the decryption processing time it is found that the AES algorithm is faster than the DES algorithm, based on the file size after the encryption process it is found that the DES algorithm and the AES algorithm have the same file size, based on the file size after the decryption process it is found that the DES algorithm and the AES algorithm have the same file size]]>

<![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.]]>

<![CDATA[Kaur 2 Public High School is one of the State Senior High Schools in Kaur District, Bengkulu Province. Communication between teachers or teachers and students or students and students has so far been carried out through text message applications that are already available on users' smartphones so that they exchange information. However, the information sent has not been fully implemented by security, where the message sent is the original message, and the recipient of the original message can read it immediately. This of course makes it easier for certain parties who intend to get the message. An android-based text message encryption and decryption application using the Advanced Encrytion Standard algorithm was created to help maintain security of communication between senders and recipients so that confidentiality is maintained. This application was created using Android Studio and has installed the JSON web service, so that it can be accessed by Android smartphone devices with the internet. Messages that have been sent will be stored in the MySQL database in the form of scrambled records, so it is necessary to do encryption to find out what the contents of the message are, where the Advanced Encryption Standard Algorithm is cryptography that uses symmetric keys (encryption and decryption keys must be the same). Based on the results of the tests that have been carried out, the functionality of the android-based text message encryption and decryption application at SMA Negeri 2 Kaur runs well as expected and the message sent between the recipient and the sender is kept confidential because the message is encrypted.]]>

<![CDATA[This study aims to create an expert system application to determine the type description of mental disorder in humans using certainty factor method. Mental Disorders are a group of symptoms characterized by changes in a person's thoughts, feelings and behavior that cause dysfunction in carrying out daily activities. The problems that often occur are the lack of knowledge and limited sources of information causing low public awareness of efforts to prevent and even treat mental disorders. The MySQL database can accommodate patient information and data who consult with an expert system that can make it easier for patients to consult about Mental Disorders. From the results of the system program on users, it was found that the average results of respondents' answers which reached 53% answered strongly agree, 26% answered agree, 14% answered less agree and only 7% of respondents answered disagree. So from the results of data processing, it can be concluded that this system is feasible to use. Because more than half of the respondents agree that this system is suitable for use]]>
