Abstract: This study aims to analyze the effect of Strategic Human Resource Management (SHRM), Organizational Culture, and Leadership on Employee Performance, both directly and through Job Satisfaction as an intervening variable, among employees of CV Vega Kontruksi Advertising. The study was motivated by declining employee performance achievement and rising absenteeism and turnover rates during the 2020-2024 period. A quantitative approach was employed using a census (total sampling) technique involving all 50 employees as respondents. Data were collected through a Likert-scale questionnaire and analyzed using Partial Least Square Structural Equation Modeling (SEM-PLS). The results show that SHRM has no significant effect on either Job Satisfaction or Employee Performance, whereas Organizational Culture and Leadership significantly affect both. Job Satisfaction significantly affects Employee Performance and mediates the relationship between Organizational Culture and Leadership on Employee Performance, but does not mediate the effect of SHRM. The study concludes that strengthening organizational culture and effective leadership, together with improved job satisfaction, are key factors in enhancing employee performance at CV Vega Kontruksi Advertising.

Penelitian ini dilatarbelakangi oleh fenomena penurunan capaian kinerja karyawan serta meningkatnya tingkat ketidakhadiran dan turnover selama periode 2020-2024. Metode penelitian yang digunakan adalah pendekatan kuantitatif dengan teknik sensus (total sampling) terhadap seluruh 50 orang karyawan sebagai responden. Data dikumpulkan melalui kuesioner berskala Likert dan dianalisis menggunakan Structural Equation Modeling berbasis Partial Least Square (SEM-PLS). Hasil penelitian menunjukkan bahwa SHRM tidak berpengaruh signifikan terhadap Job Satisfaction maupun Employee Performance, sedangkan Organizational Culture dan Leadership berpengaruh signifikan terhadap keduanya. Job Satisfaction terbukti berpengaruh signifikan terhadap Employee Performance serta berperan sebagai variabel mediasi dalam hubungan Organizational Culture dan Leadership terhadap Employee Performance, namun tidak memediasi pengaruh SHRM. Penelitian ini menyimpulkan bahwa penguatan budaya organisasi dan kepemimpinan yang efektif, disertai peningkatan kepuasan kerja, merupakan kunci utama dalam meningkatkan kinerja karyawan pada CV Vega Kontruksi Advertising.
