The learning process that has been done face-to-face in class has turned into a new habit, which is done online. Education must continue to be carried out considering that Indonesian children are the hope of the nation's future which we must prepare by learning. Information technology is one of the technologies that is growing very rapidly, even during this pandemic. SMA Negeri 1 Tanjungsari is a school located in the South Lampung area and is a superior or advanced school. However, in these schools, the lack of knowledge in the field of information technology can cause obstacles to the learning and teaching process, so it is necessary to be equipped with knowledge in the field of information technology to improve digital literacy skills and learning platforms for students in schools. In connection with the problems that have been described, this service provides a solution by holding a training and creating a learning platform based on e-learning for schools and students based on information technology. This platform was created by the team with the hope of contributing to the school as a learning centre for students. The result of this PkM program is a B-Smart application product as a learning medium for high school students and training is carried out in its operation so that it can be implemented immediately. Digital literacy skills training provides an increase in understanding in the community, seen from the pre and post tests showing an 86% increase in understanding.

Space phenomena are natural events that are rarely seen by humans and are still a lot of mysterious and interesting things to observe and study. In Indonesia, there are still few places to observe and study space phenomena. The Sumatran Institute of Technology (ITERA) has a technical implementing unit as well as a study program related to space. The units are the Lampung ITERA Astronomical Observatory Unit (UPT OAIL) and the Atmospheric and Planetary Science Study Program. However, these units and study programs do not yet have an information system that can store various space data and display them, especially for the public to see. This is the background for us to do community service for lecturers and students in the form of making the OAIL database system. The information system can be used to store space data to be studied and can be seen by the public. The form of the system is website-based so that people throughout Indonesia, especially on the island of Sumatra, can see various space phenomena. For three months, the information system was successfully created and can be implemented by UPT OAIL, so that this community service activity went according to plan and well. It is hoped that the information system can always be developed and useful for the benefit of learning at ITERA and the community. Keywords: space, database, OAIL, astronomical observatory, information system.

The interface of the automatic answer assessment system is plagued by several issues, including an unfamiliar layout, unresponsive design, inconsistency in elements, and a lack of clarity in presenting information. These problems significantly hinder the overall user experience. As a result, this study aimed to address these challenges by designing a user-centered experience for the automatic answer assessment system, using a high-fidelity prototype tailored to meet user needs. The user-centered design method involved four crucial stages: Specify The Context Of Use, Specify Requirements, Create Designs, and Evaluate Designs. Through rigorous usability testing with teachers, the design achieved an impressive effectiveness rating of 90%, firmly establishing it as a "very effective" solution. Additionally, it demonstrated high efficiency with a value of 0.01307 goals/sec, and teachers expressed positive feedback, confirming the satisfaction and usability of the new interface. Similarly, students' usability testing yielded noteworthy results, with a 90% effectiveness rating, also classified as "very effective." The interface showcased a high level of efficiency, with a value of 0.0849 goals/sec. While the satisfaction value fell below the PSSUQ norm, students still found the interface to be user-friendly and satisfactory. Furthermore, the user experience testing, utilizing the UEQ-S, provided valuable insights. For teachers, the pragmatic aspect scored 1.85, the hedonic aspect scored 2.33, and the overall aspect received a commendable score of 2.09, all of which fell within the excellent category on benchmarks. Similarly, students' ratings were highly positive, with scores of 2.14 for both pragmatic and hedonic aspects, and an overall score of 2.14, signifying an excellent user experience.The retrospective think-aloud validation test reaffirmed the positive response from prospective users. Overall, this research, employing a user-centered design approach, successfully delivered a highly satisfactory and effective user experience for both teachers and students using the automatic answer assessment system.
