Local coffee micro, small, and medium enterprises (MSMEs) in Karang Sidemen Village, Central Lombok Regency, have significant development potential; however, they still face challenges related to marketing practices and limited value addition. Conventional marketing systems restrict market reach and reduce product competitiveness. In the context of the Industrial Revolution 4.0 and Society 5.0, digital marketing offers a strategic opportunity for MSMEs to enhance product promotion and sales performance. This community service program aimed to strengthen the capacity of local coffee MSMEs through the implementation of social media–based digital marketing strategies. A participatory approach was employed, actively involving MSME actors and students through stages of problem identification, program planning, training and hands-on digital marketing practices, and evaluation. The results demonstrated an improvement in participants’ understanding and skills in utilizing social media as a promotional tool, as reflected by the initiative to develop and publish promotional video content for local coffee products, including the flagship Versilia coffee variant. The use of visual content and storytelling facilitated the practical adoption of digital marketing strategies. Overall, this program contributed to shifting marketing behavior from conventional to digital approaches and strengthening the sustainable competitiveness of local coffee MSMEs.

Ear, Nose, and Throat (ENT) health is an essential component of adolescents’ well-being and learning performance; however, health literacy related to ENT care among senior high school students remains limited. This community service activity aimed to improve students’ knowledge and basic ENT skills at SMA Negeri 9 Pekanbaru through skill lab–based learning as a school health promotion strategy. The program was conducted through theoretical education covering basic ENT anatomy and common ENT disorders among adolescents, followed by hands-on training in simple ENT examinations using demonstration and direct practice with learning aids. Evaluation was carried out using pre-test and post-test assessments to measure knowledge improvement, as well as direct observation to assess students’ practical skills. The results demonstrated a clear increase in students’ knowledge after the intervention, along with improved ability to perform basic ENT examinations under instructor guidance. Students also showed better understanding of early signs of ENT disorders and appropriate preventive behaviors. Participation and enthusiasm during the activities were high, and most students reported that the program was beneficial and relevant to their daily experiences. This activity also supported the School Health Unit (UKS) program and strengthened collaboration between the school and the university. In conclusion, skill lab–based basic ENT training is an effective promotive and preventive approach to enhancing ENT health literacy and basic clinical skills among senior high school students.

On the effectiveness of using social media as a marketing channel for MSMEs in Balikpapan. MSMEs play a major role in the national and regional economy, but developments in digital technology have caused marketing patterns to change drastically from traditional methods to online media. Social media such as Instagram, Facebook, TikTok, and X are now effective marketing tools because they are able to reach a wide audience at a low cost. However, this effectiveness is highly dependent on content quality, consistent interaction, and the right marketing strategy. Although social media offers many opportunities, MSMEs in Balikpapan still face various obstacles, such as limited human resources with an understanding of digital content, a lack of ability to read marketing metrics, and limited advertising budgets. In addition, research on the effectiveness of social media on MSMEs, especially in Balikpapan, is still minimal. Therefore, this study was conducted to analyze the extent to which MSMEs utilize social media, assess its effectiveness through indicators such as reach, interaction, and sales, and identify supporting and inhibiting factors. The results of this study are expected to provide strategic recommendations for MSMEs and theoretical contributions to the development of digital marketing models.
