Abstract

Community empowerment is a key strategy in achieving sustainable development goals, particularly in rural areas rich in natural and cultural resources. Through empowerment, communities are granted access to knowledge, skills, and resources that enable them to manage and utilize these potentials optimally and sustainably. This community service activity aims to enhance public knowledge about the benefits of red ginger (Zingiber officinale var. rubrum), which is known for its medicinal and economic properties. This program was conducted in Desa Patumbak I using an interactive lecture method, followed by an active discussion with 30 participants, including village officials, hamlet leaders, and community members. The results showed a significant improvement in participants' knowledge and skills in processing red ginger into economically valuable products. The development of red ginger-based products is expected to foster the growth of sustainable small in Desa Patumbak I. Thus, this activity has the potential to increase community income through new economic opportunities and support broader social welfare.

Abstract

This study is motivated by the rapidly evolving fashion industry and the critical need to understand consumer behavior in choosing branded bags such as Charles & Keith, highlighting the urgent need to identify key determinants of purchase decisions including brand awareness and brand image. The tested hypothesis posits that both variables jointly and individually influence purchase decisions. Employing a quantitative approach with multiple linear regression analysis, the study surveyed 50 respondents selected through purposive sampling from Charles & Keith bag consumers in Medan Johor District. The hypothesis testing revealed that brand awareness has no significant effect (t = –0,111; p = 0.912), whereas brand image exerts a positive and significant influence (t = 3.559; p = 0.001), indicating that perceptions of quality, design, and brand reputation are the primary drivers of consumer purchase decisions. These findings underscore the importance of enhancing brand image in marketing strategies. Therefore, producers and business owners should focus on improving product quality, aesthetics, and communication to strengthen brand image among consumers.
