Abstract

This study examines how On-the-Job Training (OJT), the implementation of Standard Operating Procedures (SOPs), and work professionalism affect the performance of baristas in coffee shops run as Micro, Small, and Medium Enterprises (MSMEs) in Tegal City, both individually and together. The coffee shop industry in Tegal City is growing quickly, which has led to tough competition, yet operational performance and barista service quality remain inconsistent. The study uses a quantitative, associative approach. The population consists of all baristas working in 12 MSME coffee shops across four districts of Tegal City; a saturated sample of 45 baristas was used. Data were gathered with a Likert-scale questionnaire converted into interval data using the Method of Successive Intervals (MSI), together with interviews and observations. The analysis comprised validity, reliability, classical assumption, multiple linear regression, t, F, and coefficient of determination (R²) tests. The findings show that (1) OJT has a positive and significant effect on barista performance (t = 5.490, p = 0.000); (2) SOP implementation has a positive and significant effect (t = 2.417, p = 0.020); (3) work professionalism has a positive and significant effect (t = 34.302, p = 0.000); and (4) OJT, SOP implementation, and work professionalism together have a significant effect on barista performance (F = 2204.275, p = 0.000), with an adjusted R² of 99.3%. The results highlight the need to strengthen training programs, develop standardized SOPs, and foster a professional work ethic to raise the competitiveness of MSME coffee shops.
