Despite the elimination of service fees in 2024, fluctuations in compliance (2021–2024) indicate that cost alone does not drive participation; service system aspects play a significant role. This research employs a quantitative approach using a survey method. The population consists of 1,324 traders who had not conducted verification or re-verification in four traditional markets in Malang City. A total of 307 respondents were selected using proportional stratified random sampling. The independent variables include accessibility, availability, service quality, efficiency, and effectiveness, while the dependent variable is mandatory verification awareness. Data were collected through questionnaires, interviews, observations, and documentation. Data analysis techniques included validity and reliability testing, descriptive analysis, partial t-tests, and simultaneous F-tests. The results indicate that all research instruments are valid and reliable. Descriptively, accessibility is categorised as good (mean = 3.824), availability as moderately good (mean = 3.188), and service quality as moderate (mean = 3.015). These findings suggest that improvements are particularly needed in the dimensions of accessibility, availability, service quality, efficiency, and effectiveness. Simultaneously, the service system has a significant effect on mandatory verification awareness. Therefore, enhancing the service system through improved information access, optimisation of human resources, strengthening of staff competence, and increased service efficiency and effectiveness can serve as strategic measures to raise mandatory verification awareness and achieve measurement orderliness in Malang City.</p>2026-06-12T00:00:00+00:00Copyright (c) 2026 Enrichment: Journal of Multidisciplinary Research and Developmenthttps://mail.journalenrichment.com/index.php/jr/article/view/679 Sthe Effect of Micro-Influencers on Brand Trust and Buying Decisions, with Brand Preference as a Mediating Variable and Micro-Influencer Brand Selfies as a Moderating Variable, Among SMEs (Food Businesses in Purwokerto)2026-06-05T02:57:11+00:00Meliyana Rizki Prabaningrummeliyana.rizki.p@mhs.unsoed.ac.idNajmudin Najmudinnajmudin@unsoed.ac.idSudarto Sudartosudarto1907@unsoed.ac.id<p>In the digital marketing era, micro-influencers have become a powerful force in shaping consumer behaviour, particularly for small and medium enterprises (SMEs) in the food sector. This research investigates the influence of micro-influencer brand trust on consumers' buying decisions, with brand preference as a mediating variable and micro-influencer brand selfie as a moderating variable, in the context of small and medium food enterprises in Purwokerto. The research employs a mixed-methods approach, combining surveys to examine relationships among variables and interviews to explore consumers' experiences, perceptions, and motivations. The study is grounded in Social Identity Theory, proposing that consumers form social identities through engagement with local micro-influencers, which strengthens trust in the brand and enhances brand preference. Additionally, personal content such as brand selfies is expected to reinforce the effect of influencer trust on consumer attitudes. The findings indicate that micro-influencer brand trust positively affects brand preference and buying decisions, with brand preference serving as a key psychological mechanism, while brand selfies amplify this influence. The study contributes theoretically by applying Social Identity Theory to local influencer marketing, offering a deeper understanding of consumer–influencer interactions. Practically, it provides insights for SMEs to optimise their marketing strategies through authentic and engaging influencer content that effectively encourages consumer purchases.</p>2026-06-12T00:00:00+00:00Copyright (c) 2026 Enrichment: Journal of Multidisciplinary Research and Development
