This research was carried out due to the prevalence of ransomware attacks, especially in Indonesia against data located at Endpoints, in early 2022 ransomware was enough to horrify the news in cyberspace and one of the ransomware that is quite worrying in Indonesia is LockBit 2.0 ransomware, so research is needed against the ransomware. The method used to research the ransomware is static analysis and dynamic analysis which will show the infection and persistence of the LockBit 2.0 ransomware, the static analysis method is used by reverse engineering the portable executable (PE) file and the dynamic analysis method is carried out by running the ransomware. then look at the operating activities, the resources used, and including the network activities carried out by the ransomware and its impact on the affected operating system, so that a scenario for prevention methods can be made, where in this study we can see the real impact of the attacks carried out by the LockBit 2.0 ransomware which is also part of ransomware-as-a-services (Raas), as well as 5 steps that can be taken to avoid it and can make anyone aware with ransomware attacks that’s why create artificial intelligence that accommodates such vigilance is important.Keywords—Ransomware, LockBit 2.0, Infection, Persistence, Prevention

Every information that attractive and easy to understanding is very important to give big impact for every primary school student, it also can provide a pleasant learning experience for these students. Therefore, this research develops a smartphone application that can provide a pleasant experience in learning knowledge of the surrounding environment from objects with virtual reality technology. To display these objects, a 360 ° panoramic image is used or a 2048px width 1024px width with a wide viewing angle (360 degrees) and this can be done by teachers to make the image or search for material sources on the internet. This technology allows students to see objects virtually. In use, this study requires a VR headset as a device for visualizing stereoscopic displays but it does not need installation because it is enough to access a smartphone browser then it will work. The system is designed using the spiral method as a process model and uses a-frame in application development. The interface can be run on the Android operating system. In making this application using the html programming language, laravel framework and a-frame framework.
