Gajah Mati Village, Central Bengkulu is one of the developing villages in terms of development and technology. Gajah Mati Village has people who in general have a great interest in using digital media on smartphones to carry out various daily activities in finding various information, so it is considered necessary to provide an understanding related to current fake news (hoaxes) on social media. , where with the development of technology including applications, hoaxes are felt to be increasingly sophisticated and diverse, which if delivered continuously and repeatedly, it is as if they are considered to be something that is not fake anymore aka the truth. In order to provide understanding and knowledge related to hoaxes, community service activities were carried out in the form of socializing about theoretical exposures about hoaxes on social media, types of hoaxes with various modes, then continued with various ways of tackling the hoax, which were then given various examples of hoaxes. nowadays in increasingly sophisticated social media where the sophistication of the hoax is assisted by various applications that make it seem as if the hoax is true or real. The subjects in this service activity were the Head of Gajah Mati Village and his apparatus and all residents of Gajah Mati Village, Central Bengkulu. The output targets to be achieved in this community service activity are (1) the people of Gajah Mati Village, Central Bengkulu, are able to understand the importance of recognizing the current hoaxes that are developing on social media, and (2) the people of Gajah Mati Village, Central Bengkulu, are able to overcome various hoaxes. and not being "eaten" by various hoaxes that can be very disturbing, which are present on social media.

Analysis of the pattern of guest visits at the Rio Asri Bengkulu Hotel with the a priori algorithm is carried out to obtain rules and predict the next guest visit and provide guests with marketing rewards to increase the interest of other visitors in utilizing and using hotel services regularly or periodically. A priori analysis is defined as a process to find all the rules that meet the minimum requirements for support and the minimum requirements for confidence. The implementation of the system uses the Visual Basic 2010 programming language and the method used in this study is the waterfall method. The results of the analysis carried out with the variables used are arrival time, number of guests, area of origin and class of room chosen by guests, it is found that the itemset with the best pattern is influenced by the specified minimum support value.

Security issues are one of the most important aspects in the world of information technology, such as document security. Most of the documents are created through the Microsoft Office application package, because it is easy to use. There are several applications available in Microsoft Office, namely Microsoft Word, Microsoft Excel, Microsoft Access, Microsoft Powerpoint, and others that are used to process words and numbers according to user needs. Comparative analysis of the Blowfish algorithm and the DES algorithm in the encryption process is carried out based on 3 comparison aspects, namely processing time, file size and memory used. Comparisons were made with 40 test data in the form of document files, each consisting of 10 test data with extension formats *.docx, *.xlsx, *.pdf, and *.pptx, where these formats are familiar in data processing using Microsoft Office. Based on the tests that have been carried out, it can be concluded that in the encryption process, the DES Algorithm has a faster time than the Blowfish Algorithm with a percentage of the DES Algorithm's encryption processing time of 3.7975%. In the decryption process, the DES Algorithm has a faster time compared to the Blowfish Algorithm with a percentage of the DES Algorithm's encryption processing time of 3.595%. In the encryption process, the file size in the DES Algorithm increases bytes less than the file size in the Blowfish Algorithm. In the decryption process, the file size in the DES Algorithm and the Blowfish Algorithm does not change, because the file size returns to the original file size. In the encryption process, the DES Algorithm uses less memory compared to the Blowfish Algorithm with the percentage of memory used by the DES Algorithm being 49.655%. In the decryption process, the Blowfish Algorithm uses less memory compared to the DES Algorithm with the percentage of memory used by the Blowfish Algorithm 49.5925%
