Abstract

This study aims to analyze the feasibility of a coffee shop business in Lidah Wetan, Lakarsantri District, Surabaya City. The method used is a case study with a qualitative approach, which focuses on the analysis of three main feasibility indicators: Revenue Cost Ratio (R/C Ratio), Benefit Cost Ratio (B/C Ratio), and Return On Investment (ROI). Data were collected through observation, interviews, and documentation studies from six coffee shops as samples. The results of the study indicate that all business units analyzed are declared feasible to run. This is evidenced by the value of the three financial ratios which are consistently above the feasibility threshold (>1). The average R/C Ratio of 3.98 indicates that every Rp1 of costs incurred generates revenue of Rp3.98. The average B/C Ratio of 2.98 indicates that every Rp1 of costs generates a net profit of Rp2.98. Meanwhile, the average ROI of 2.98% proves that the investment made provides a positive return.

Abstract

The development of e-commerce in Indonesia has shown significant growth, particularly with the increasing use of mobile applications for transactions. Shopee, as one of the largest e-commerce platforms in Indonesia, has experienced a notable increase in market share across various demographic groups. However, market dominance does not automatically guarantee customer loyalty. This study aims to analyze the influence of electronic service quality (e-service quality) and electronic trust (e-trust) on electronic customer loyalty (e-customer loyalty) on Shopee. The method employed is a literature review with a qualitative descriptive-analytical approach, through the collection and synthesis of relevant previous studies. The analysis results indicate that e-service quality plays a crucial role in shaping positive customer perceptions through fast, accurate, and responsive services, while e-trust enhances customer confidence in the platform’s security, reliability, and transparency. Both factors significantly affect customer loyalty, either directly or through the mediation of customer satisfaction (e-satisfaction). This study contributes to the development of e-commerce strategies, particularly in enhancing digital experiences, building customer trust, and maintaining Shopee’s customer loyalty sustainably.

Abstract

The rapid development of digital technology has created a new economic ecosystem through the integration of social media and marketing activities, particularly the TikTok Affiliate program. This program allows affiliates to earn performance-based income by influencing consumer purchasing decisions through creative and interactive content. This study aims to analyze TikTok affiliate content strategies in increasing income through consumer trust and behavior. The research employed a qualitative method with a literature review approach by analyzing various scientific sources related to affiliate marketing, consumer behavior, and social media algorithms. The results show that creative, relevant, and consistent content strategies significantly influence consumer trust and loyalty, which in turn increase affiliate income. Understanding the TikTok algorithm also plays an important role in determining the reach and effectiveness of promotional content. However, challenges such as limited promotional regulations, intense competition, and inequality between large and small affiliates remain obstacles. Overall, the TikTok Affiliate program has a positive impact on digital economic growth and the empowerment of Indonesia’s creative economy.

Abstract

This study aims to analyze the influence of taste, packaging, and price perception on repurchase intention with customer satisfaction as a mediating variable among Mixue consumers in East Surabaya. The research method used is quantitative with purposive sampling technique and involved 100 respondents who have made purchases more than three times. Data collection was carried out by distributing questionnaires that have been tested for validity and reliability. Data analysis used the Structural Equation Modeling (SEM) approach with the Partial Least Square (PLS) method through SmartPLS 3.9.9 software. The results showed that taste and price perception have a positive and significant effect on repurchase intention, while packaging has a positive but insignificant effect. Taste and price perception are also proven to have a positive and significant effect on customer satisfaction, while packaging again shows a positive but insignificant effect. In addition, customer satisfaction has a positive and significant effect on repurchase intention. The mediating role of customer satisfaction is proven to be significant in the relationship between taste and price perception on repurchase intention, but not significant in the relationship between packaging and repurchase intention. These findings indicate that product taste and perceived price to quality play a dominant role in increasing customer satisfaction and driving repeat purchase intentions among Mixue consumers.
