Kontribusi Motivasi Kerja dan Disiplin Kerja terhadap Kinerja Karyawan di Cafe Empat Kota Serang

This research investigates the influence of employee motivation and work discipline on staff performance at Cafe Empat, located in Serang City. In the hospitality and food service industry, human resources serve as a critical element for operational success due to continuous face-to-face customer interactions. Utilizing a quantitative, causal-associative framework, this study examined the entire population of 45 employees using a total sampling technique. Primary data gathered via structured Likert-scale questionnaires were processed using IBM SPSS v.26 for multiple linear regression analysis, following rigorous classical assumption testing (normality, multicollinearity, and heteroscedasticity). Results show that work motivation has a significant positive effect on employee performance (t = 4.217; p < 0.05), as does work discipline (t = 3.985; p < 0.05). The F-test confirms that both variables jointly exert a significant positive influence on performance (F = 29.843; p < 0.05). The coefficient of determination (R2 = 0.684) indicates that 68.4% of variance in employee performance is explained by these two variables, while the remaining 31.6% is attributed to factors not included in the model. Management is advised to consistently develop motivational programs and enforce disciplinary standards to sustain productivity and competitive advantage.
