ABSTRACT: The purpose of this study was to examine how work ability and motivation affect employee performance, as well as how work ability and motivation together affect employee performance at the Siluq Ngurai Sub District Head office in  Kutai Barat Regency. The Siluq Ngurai District Head Office in the Kutai Barat Regency of East Kalimantan Province Indonesia was the site of this study.  Multiple linear regression analysis was the method employed. The study found that work ability has a positive and significant impact on employee performance, while work motivation has a positive but non-significant impact. Additionally, the combination of work ability and motivation has a positive and significant impact on employee performance at the Siluq Ngurai Sub District Office in Kutai Barat Regency. It can be suggested that the local administration, and in particular the Head of Siluq Ngurai Sub District, make sure that workers are constantly inspired by, for instance, offering appropriate rewards and creating a positive work environment. Similarly, by enhancing employee proficiency through training, the government may maximise personnel talents.
