PEB Cooperative is a savings and loan cooperative which is intended for employees of PT. PEB, is engaged in the garment industry. Established since 15 years with the number of cooperative members who are permanent employees of the company. This cooperative becomes an economical shelter to meet the needs of its employees. Technology in admin data processing is still simple using Microsoft Excel tools, in applications that connect members with admins on this system have not been designed, so from the background of this research will design a web-based and android-based savings and loan cooperative information system This design uses the waterfall model which will take a sequential design making it easier for developers and users. The hope is that this design will help make transactions for savings, loans, deposits, data collection, and reports to members, admins and leaders. The results obtained from the questionnaire with the System Usability Scale method in this savings and loan cooperative application are easy to use, faster, and practical, stated by the cooperative members by 84% and cooperative managers by 80%. It can be concluded that this application that has been designed can make it easier to carry out savings and loan transactions quickly and practically.

ABSTRACT It has been a year since the Covid-19 pandemic has occurred in Indonesia, starting from the tourism sector, the economy, and others including education. Of course, the learning and assessment process becomes difficult to carry out, one of which is at the Nafidatunnajah Islamic Boarding School which is located on the border in Rawakalong, Gunung Sindur, Bogor Regency. The Nafidatunnajah Islamic Boarding School has formal education including vocational education, MTS, and MI. Information technology and computers which can now be used are very important factors in the world of education, from offline face-to-face learning to online using e-learning, Zoom meetings, including changing Paper Based Tests to Computer Based Tests (CBT). This research uses Rapid Application Development (RAD) software model and Unified Modeling Language tools. With the development of this CBT model, it is hoped that it can provide a solution for testing the entrance test which will be measured using the System Usability Scale method. For teachers, the user responses were taken by 10 teachers and for prospective students, the user responses were taken for 20 students by being tested using a web-based CBT application on a browser on each computer, then filling out a questionnaire sheet. The output obtained by using the System Usability Scale in this application is ease of use, more practical and faster, this is stated by prospective students by 77% and teachers by 76%.   Keywords: Computer Based Test, RAD, Web, Unified Modelling Language, System Usability Scale

The presence of the ambulance patrol is sometimes considered disturbing by the community, many people's opinions are still pro and contra about the actions carried out by civilian ambulance patrol volunteers because they are considered illegal and sometimes also arrogant. In this study. the researchers wanted to know the opinions and responses of the public about the actions taken by civilian ambulance patrol volunteers. The method used in this study is to perform sentiment analysis with data mining techniques to find the polarity of sentences in a document using the Naïve Bayes and Decision Tree algorithms. The initial steps in this research were collecting comment data by scraping YouTube comments using API Key Youtube V3, followed by manual data labeling, data cleaning, data preprocessing, and word weighting using TF-IDF. From the overall results of testing with 600 training data, the Naïve Bayes algorithm has a higher accuracy value of 66.72% while the Recall value is 64.98%. Testing with the Decision Tree algorithm in this study has a higher Recall compared to Naïve Bayes. %. From the results of the YouTube comment dataset used in this study, it can be concluded that the Naïve Bayes algorithm has a higher accuracy value than the Decision Tree algorithm, so it can be concluded that Naïve Bayes has the best accuracy in the YouTube comment dataset used in this study.
