The rapid growth of RT/RW Net-based internet services among the community has driven the need for an integrated, efficient, and easy-to-use billing system. The self-help RT/RW Net model often faces challenges in terms of administrative management, especially related to customer recording, billing, and financial reporting which are still done manually. Common problems faced by partners are payment systems that have not been digitized and minimal transparency in data collection and tracking of customer transactions. The purpose of this activity is to design and implement a web-based billing application built using the Laravel framework. This application is designed to facilitate the process of managing customer bills, monitoring internet service usage, and preparing financial reports automatically and in a structured manner. The method of implementing the activity includes the system design stage, training partners in using the application, and assistance in direct implementation in the RT/RW Net operational environment. The results of the activity show that the developed system has succeeded in automating most of the billing process and increasing the efficiency of administrative management by up to 80%. In addition, this system also has a positive impact on increasing transparency and accuracy of customer data. Suggestions for further development include the addition of automatic payment features through integration with payment gateways, as well as improving the user interface to make it more responsive and user-friendly.

Courses related to procedural law are practicum courses with Course Learning Outcomes (CLO)/ Capaian Pembelajaran Mata Kuliah (CPMK) students who can simulate trials in court. In this case, the moot courtroom's urgency is to provide an infrastructure for students to conduct moot trials. One of the practicum courses is the Constitutional Court's Judicial Procedural Law. Students who take this course must be competent and able to practice in the objective realm of justice. However, based on the observation and tracing results, the service activities' partners do not have a moot courtroom in the constitutional court, so they cannot carry out moot court in the course. Digital/virtual space, known as Metaverse, is a solution for procuring infrastructure for the constitutional court's moot courtroom. The results of this service show that the Metaverse Moot Court of the Constitutional Court is an appropriate technology-based product that is the only quick solution to the absence and limitations of the Constitutional Court's moot courtroom at Partner universities. Partners do not need to spend millions to billions of Rupiahs to procure facilities and infrastructure for the Constitutional Court's moot courtroom. In addition, this product is a solution to time constraints, considering that the campus has operational hours while students are still required to be proficient in practicing proceedings at the Constitutional Court. Finally, the virtual reality technology product implemented in this pseudo-courtroom provides an immersive experience like the real atmosphere in the courtroom. It makes students more excited and increases motivation to practice the trial.

Radar is a tool that functions to determine the whereabouts of objects in the surroundings. A military defense system requires a system for monitoring and handling certain areas (land, sea, air) effectively and efficiently to prevent unwanted presence from entering private areas. This design is expected to increase the defense system's capabilities to make it easier to automatically track and destroy enemies. The laser gun is an actuator that is integrated to shoot enemies detected by radar. The servo motor drives the ultrasonic sensor and the diode laser which moves from 00 to 1800, the ultrasonic sensor is integrated into the servo motor which functions to detect objects by reflecting ultrasonic waves on the object and receiving them back when the waves hit the object, then the 5V diode laser is used as a weapon. will emit a laser beam when directed at an object detected by the servo motor. Processing3 software is used as a graphic programming tool that can display object detection read by the ultrasonic sensor. The results of this research are that the ultrasonic sensor is capable of detecting objects in the range 0-40cm and the servo motor is capable of reaching angles from 00 to 1800. And this system can work effectively during shooting so that it can meet defense needs in dealing with enemies and can work quickly and precisely.
