This study investigates the influence of employing Atta Halilintar as a brand ambassador on the improvement of products and services at Bank Syariah Indonesia (BSI) through the lens of business communication. The research employs a quantitative approach with data collected via questionnaires from 100 respondents, both BSI customers and non-customers. Respondents assessed seven key variables: awareness, image, relevance, product knowledge, purchase intention, word of mouth, and engagement. The findings reveal that the brand ambassador has a moderate impact on strengthening BSI’s products and services, with average scores falling within the “fair” range of 2.76–3.1 on a four-point Likert scale. Awareness recorded the highest score of 3.1, reflecting the effectiveness of Atta Halilintar in enhancing brand recognition among the younger generation. Conversely, purchase intention received the lowest score of 2.76, suggesting that although awareness and positive image improved, they have not yet translated into higher conversion rates or actual product usage. These results highlight that the presence of a brand ambassador primarily boosts visibility and engagement but requires complementary strategies such as product education, interactive campaigns, and community-based marketing to achieve stronger customer adoption. Thus, the study underscores the importance of integrating brand ambassador initiatives with broader business communication strategies to maximize both awareness and transactional outcomes in Islamic banking.

This study aims to analyze the influence of brand ambassadors, sales promotions, and brand image on the purchase intention of Mie Lemonilo products in Balikpapan.

Primary data were collected through a questionnaire distributed to followers of the Mie Lemonilo Instagram account in Balikpapan, while secondary data were gathered from various supporting sources. The population in this study consisted of all followers of the Mie Lemonilo Instagram account in Balikpapan, with a sample size of 100 individuals. The results of the study indicate that Brand Ambassador (X1) does not significantly influence the purchase intention of Mie Lemonilo. This suggests that the impact of the brand ambassador on consumer purchasing decisions in Balikpapan is not strong enough, possibly due to insufficient engagement or connection between the brand ambassador and consumers. In contrast, Sales Promotion (X2) has a significant positive impact on the purchase intention of Mie Lemonilo. This indicates that sales promotions, such as discounts or special offers, have a substantial effect in attracting consumer interest and increasing purchase intention in Balikpapan. Meanwhile, Brand Image (X3) does not show a significant influence on the purchase intention of Mie Lemonilo. This may be due to other factors being more dominant in influencing consumers’ purchase decisions, such as product price, quality, or social factors and market trends. This study provides insights that, although brand image is important, sales promotions play a more significant role in driving purchase intention for Mie Lemonilo products in Balikpapan. Therefore, the company should focus more on promotional strategies to increase sales while continuing to consider the role of brand ambassadors and brand image in their marketing strategies.
