The main problem addressed in this study is how to enhance employee performance by equalizing employee competencies to support the implementation of a safety culture and reduce job insecurity. This research applies a quantitative, associative-causal approach using a dual mediation model. The study was conducted on employees of PT PLN Indonesia Power UBP Suralaya, with a total population of 527 employees. The study involves four variables with a total of 16 indicators; thus, the required sample size was determined as 10 times the number of indicators, resulting in 160 respondents, selected using stratified proportional sampling. Data were collected via an online questionnaire and analyzed using the SEM-PLS model with SmartPLS version 4.0. The research findings indicate that five out of seven proposed hypotheses are supported, specifically: (1) competency has a positive and significant effect on employee performance; (2) competency has a positive and significant effect on safety culture; (3) competency has a negative and significant effect on job insecurity; (4) safety culture has a positive and significant effect on employee performance; and (5) safety culture significantly and partially mediates the effect of competency on employee performance. The study also found that job insecurity does not significantly affect employee performance and does not mediate the effect of competency on employee performance. date: 2025 type: Thesis type: NonPeerReviewed format: text language: en identifier: https://eprints.untirta.ac.id/52183/1/KRISLOANA%20KENDALI_7776230055_Fulltext.pdf format: text language: en identifier: https://eprints.untirta.ac.id/52183/2/KRISLOANA%20KENDALI_7776230055_01.pdf format: text language: en identifier: https://eprints.untirta.ac.id/52183/3/KRISLOANA%20KENDALI_7776230055_02.pdf format: text language: en identifier: https://eprints.untirta.ac.id/52183/4/KRISLOANA%20KENDALI_7776230055_03.pdf format: text language: en identifier: https://eprints.untirta.ac.id/52183/5/KRISLOANA%20KENDALI_7776230055_04.pdf format: text language: en identifier: https://eprints.untirta.ac.id/52183/6/KRISLOANA%20KENDALI_7776230055_05.pdf format: text language: en identifier: https://eprints.untirta.ac.id/52183/8/KRISLOANA%20KENDALI_7776230055_Reff.pdf format: text language: en identifier: https://eprints.untirta.ac.id/52183/9/KRISLOANA%20KENDALI_7776230055_Lamp.pdf identifier: KENDALI, KRISLOANA (2025) PERAN SAFETY CULTURE DALAM MENINGKATKAN KINERJA PEGAWAI (Studi di PT PLN Indonesia Power UBP Suralaya).
