Knowledge must be managed effectively to facilitate transfer between individuals, groups, and organizations. The Informatics Engineering study program currently lacks a system for knowledge management. Currently, the study program facilitates offline discussion forums for the sharing of knowledge gained by lecturers and students. These offline discussion forums require significant costs, time, and space, often resulting in delays in knowledge sharing. This research focused on the analysis and design of a Knowledge Management System to meet the needs of Informatics Engineering students at Universitas PGRI Madiun. The system development method used was the Knowledge Management System Lifecycle (KMSL). In this study, the TIF KMS system using the KMSL method has been successfully built. The results of testing using the Blackbox Testing method showed that 5 scenarios and 18 cases were successfully executed as expected with a 100% success rate. Based on the system test results, the TIF KMS is ready to proceed to the implementation stage. Future implementation can be done by developing additional features such as a digital library

School promotions were carried out directly by visiting junior high schools, during a pandemic this can’t be done. In an effort to attract prospective new students at SMK PGRI 2 Salatiga, it is necessary to innovate by adding promotional media that can be accessed by the wider community. Information distribution can be done through social media and the school's YouTube channel. Information media was chosen as virtual reality in the form of 360° videos to display school facilities and privileges. The measurement indicators used in this study are behavior, interactivity, and sound to find out whether the virtual environment can affect the interest of prospective students at SMK PGRI 2 Salatiga. In addition, the interactivity of the video when it is played and the sound of the environment in the video can give immersive in a school environment. The results of this study by the majority of respondents stated that promotional media virtual reality in the form of 360° videos is appropriate for use for school promotions during a pandemic, as an effort to increase the number of new students.

The more rapid development of universities in Indonesia, the competition between universities is getting bigger so that the quality and facilities of each university greatly affect the attractiveness and competitiveness of universities. College of Computer Informatics Management (STIKOM) Uyelindo Kupang has 672 students. The campus of STIKOM Uyelindo Kupang has three departments, namely, first-class informatics engineering, undergraduate information systems and D3 informatics engineering with each accredited B. The development and improvement of lecture and practicum facility services at (STIKOM) Uyelindo Kupang is very important to be monitored and maintained. If the campus has provided services and facilities for students but these services and facilities are not monitored and maintained, sooner or later the services and facilities provided will be damaged and can no longer be used. The purpose of this research is to build a complaint information system website for lecture facilities and practicum to help and facilitate students. Based on the results of the test analysis using the Slovin method, there is an average value of 87% with Strongly Agree (SS) criteria. Even with the index value, when viewed based on the type of variable, there are several question items with unfavorable criteria. Question items with these criteria need to be considered for future website development. In the future, the website development will take into account the lowest index value of each indicator, especially those with poor and bad criteria.

Virtual teachers are devices or agents with the function of replacing the role of humans (teachers) with their teaching skills. The virtual teacher also has a function as task facilitator and is presented during training, especially when the teacher is actually not present. The virtual teacher's objectivity is carried out by explaining the subject matter in a virtual environment, for example, virtual independent learning. In the western world, virtual schools are quite widely applied, especially to students who are homeschooling. In a virtual school, all materials, assignments and grades are accessed via the internet. The virtual teacher concept refers to a device that provides guidance and practice. Teachers who are equipped with interactive agent functions that can provide direction and feedback in order to improve student abilities. By utilizing natural language processing (NLP) and pattern matching to help students learn alone without being accompanied by a teacher. NLP is used as a learning tool as outlined in the text of the sentence as part of the learning material which is done virtually. Meanwhile, pattern matching is used to group the questions asked so that the computer can gain an understanding of the questions posed by students. This grouping aims to solve problems with different word order which basically have different meanings. The teacher has the facility to make material, make questions, and answer student questions. A teacher can add knowledge about the database to enrich the source of knowledge for students.

The development of information systems is increasingly rapidly nowadays requires a lot of educational institutions to develop information systems in educational environments that do not fall behind with other educational institutions. It's possible the parents and students will move to the educational institutions that have information systems that fast, accurate and reliable way to get the information required with skills no doubt in supporting the learning system. SMK Negeri 4 Kendal is located at Jl. Soekarno-Hatta Kendal, very aware of the importance of information systems. The information that fast, accurate and available at all times would be very helpful in the implementation of the learning process is also in the process of admission of new students. A newly established education institution four years ago was very concerned about the availability of information systems needed by students and parents so that information systems and the fabric of cooperation to do with ease. The purpose of this research is to increase the number of new admissions and quality of service in the admission of new students and in conducting the data collection and reporting so that information needed by prospective students as well as guardians and leaders mmurid can be obtained at any time. In this research, the application used is PHP programming MySQL database.
