Abstract

The culinary industry in Indonesia, particularly the dimsum sector, is undergoing rapid development in response to increasing consumer demand for practical and flavorful ready-to-eat meals. This study aims to analyze and optimize the production strategy of Dimsum Kota Medan by applying linear programming using the primal simplex method. The research adopts a case study approach, with data collected through direct interviews and observations to identify production goals, decision variables, and existing operational constraints such as labor, raw materials, and time availability. The simplex method is then applied to determine the optimal production combination that yields the highest profit. The findings show that to achieve a maximum daily profit (Zmax) of IDR 19,800,000, the enterprise should produce 60 portions of original dimsum (X1) and 60 portions of hakau dimsum (X2). Although the model operates under the assumption of linearity and does not capture all external market dynamics, it offers practical guidance for decision-making in resource allocation. This study demonstrates the relevance of mathematical optimization techniques in enhancing profitability for small and medium-sized culinary enterprises in a competitive market environment.

Abstract

This study aims to analyze the influence of Content Marketing Strategy and Promotion on Customer Loyalty at TOP Advertising. This study uses a quantitative method with primary data obtained through distributing questionnaires to 126 respondents using a saturated sample method. Data analysis was carried out using descriptive statistics, classical assumption tests, multiple linear regression, partial tests (t-tests), simultaneous tests (F-tests), and coefficient of determination (R²) tests. The results show that Marketing Strategy has a positive and significant effect on Customer Loyalty with a t-value of 1.660 > t-table 1.657 and a significance level of 0.000 < 0.05. This finding is in line with the research of Setiayasa et al. (2024) and Darado et al. (2023) which also stated that Marketing Strategy has a significant effect on Customer Loyalty. Meanwhile, Promotion does not have a significant effect on Customer Loyalty, with a t-value of 0.843 < t-table 1.657 even though it has a significance level of 0.000 < 0.05. Simultaneously, Marketing and Promotion Strategy does not have a significant effect on Customer Loyalty, indicated by the Fcount value of 1.770 < Ftable 3.07 with a significance of 0.000 < 0.05. The results of the determination coefficient (R²) test of 0.427 indicate that 42.7% of the variation in Customer Loyalty can be explained by Marketing and Promotion Strategy, while the remaining 57.3% is influenced by other factors outside this study, such as service quality, trust, and customer satisfaction.
