Community service initiatives often struggle to meet the needs of beneficiaries. This study explores the application of Importance Performance Analysis (IPA) to improve the effectiveness of community service programs, using Solaria Restaurant’s customer service efforts as a case study. The research investigates the gap between beneficiaries’ expectations and their perceptions of delivered services.  Data is collected through surveys administered to a sample of Solaria Restaurant patrons who have benefitted from the restaurant’s community service programs.  By analyzing the importance and performance ratings provided by participants, the study identifies areas for improvement within Solaria’s service delivery. This research demonstrates the value of IPA as a tool for enhancing community service programs. By aligning service delivery with beneficiary expectations, organizations can maximize the impact of their efforts and create more meaningful community engagement.

Indonesia is a country with diverse culture and tourism. The rapid development of technology causes changes. Sukaraja village has religious tourism potential which has not been utilized optimally through social media.  The BATU GOONG Cultural Heritage Site and its MSME actors are one of the main attractions, but have not utilized platforms such as Instagram, TikTok, Facebook and Twitter for promotion. Therefore, there are three stages of activity plans which include training on creating social media accounts, tourism and MSME digitalization seminars, as well as developing Instagram and Facebook content. These three stages aim to increase the promotion of Batu Goong religious tourism so that there will be an increase in visitors.

Linux kernel security is a critical aspect of ensuring the integrity and stability of operating systems. Vulnerabilities like Dirty COW (CVE-2016-5195) illustrate how exploitative threats can severely impact systems, particularly those that are not regularly updated. This study analyzes the working mechanism of Dirty COW, its impact, and mitigation strategies based on Linux kernel hardening techniques, including the use of security modules like SELinux and AppArmor, as well as the Address Space Layout Randomization (ASLR) technique. Through attack simulations and mitigation evaluations, the findings emphasize the importance of regularly applying kernel patches to maintain system security. This study aims to provide practical guidance for enhancing Linux kernel resilience against exploitation attacks.
