At school, especially in Automotive Vocational High Schools, a learning process is carried out by helping students to recognize and overcome problems that occur in motorbike/car damage. One of the SMKs that has an Automotive expertise program is SMK Negeri 2 Bengkulu City. So far, the automotive learning system has used books and pictures to support the learning process at school. However, this sometimes has problems, where students do not fully understand the material given, and on the other hand students have difficulty learning independently either in the school environment or at home. Expert systems in helping students diagnose car engine damage using the Expert System Development Life Cycle (ESDLC) method can be accessed online with internet access via the web link http://riska.vad.my.id. This expert system application is made using the PHP programming language and MySQL database. This expert system application has been embedded with the ESDLC method with the Forward Chaining inference engine which is used to trace damage to car engines based on the symptoms experienced by the car engine. This expert system application can help facilitate the understanding of students at SMK Negeri 2 Bengkulu City in diagnosing car engine damage, by providing consultation directions starting from entering symptoms to getting consultation results. Based on the system testing that has been done, it can be concluded that the functionality of the application has been running well and this expert system can provide consultation results based on the symptoms selected by the user through the stages of the Expert System Development Life Cycle (ESDLC) method.

Digital awareness is a deep and comprehensive understanding of the digital world, encompassing technology, devices, the internet, and the environment and culture that shape it. It is a state in which a person is not only able to use digital technology (digital skills) but also understands the impacts, risks, ethics, and potential benefits of using that technology in everyday life. Someone with high digital awareness will act wisely, critically, and responsibly when interacting, consuming, and producing information in the digital space. This community service activity aims to provide students of SMA Muhammadiyah 4 Bengkulu with an understanding and skills to understand the importance of digital awareness in social media. Furthermore, through training and mentoring, students are provided with the opportunity to utilize the concept of digital awareness to avoid negative aspects of social media. This community service provides and demonstrates students' awareness of positive social media use and what to avoid to minimize the negative impacts resulting from carelessness. Digital awareness provides positive information on students' level of understanding and skills, encouraging them to remain aware of the influence of digital technology, which can have negative consequences if they lack a good understanding of digital awareness.

Gotong royong is a noble tradition of the Indonesian people that has declined in the modern era, particularly in urban areas. This study examines the revitalisation of the gotong royong culture as a strategy for sustainable waste management in RT 08 RW 02, Sawah Lebar Village, Bengkulu City. The main issues include low resident participation in collective activities, a lack of awareness regarding waste sorting, and a shortage of environmental education materials. Implementation methods included Focus Group Discussions, scheduled community work sessions, the installation of visual educational materials, waste sorting training, and a partnership with the Waste Bank. The results of the activities showed an increase in resident participation to 75%, the installation of educational signs on waste decomposition periods, the implementation of a mandatory reporting system for boarding house residents, and the successful deposit of plastic waste at the Waste Bank. This programme successfully fostered collective community awareness in maintaining environmental cleanliness by utilising the local wisdom of community cooperation.
