Abstract

This study investigates the factors influencing the performance of administrative staff at Muyang Kute Regional General Hospital, a government-owned healthcare facility in Bener Meriah, Indonesia. Utilizing an analytical survey with a cross-sectional design, data were collected from 89 permanent administrative staff members through questionnaires and hospital documents. Bivariate analysis, using the chi-square test, revealed a significant relationship between incentive provision and employee performance (p<0.001), with adequate incentives correlating with good performance. Similarly, effective employee development significantly impacted performance (p<0.001), with effective development programs leading to better performance. However, work facility provision did not significantly influence performance (p=0.475). The findings highlight the critical role of incentives and employee development in enhancing administrative staff performance, suggesting that targeted interventions in these areas could improve service quality and patient satisfaction.

Abstract

Background: Metal-ceramic crowns remain a primary choice for dental restoration due to their adequate mechanical strength and relatively low cost. However, their esthetic success depends on the color stability of the porcelain, particularly the opaque layer that masks the underlying metal. Nanosilica derived from rice husks is an environmentally friendly material with potential as a reinforcing agent, but data on its effect on color changes in metal-ceramic crowns remain limited. This study aimed to analyze the effect of adding 0.5% rice husk nanosilica to the opaque layer on color changes in metal-ceramic crowns. Methods: An in vitro experimental study used Co-Cr metal samples coated with porcelain, with color evaluation based on the CIELAB system (L*, a*, b*) via colorimeter before and after nanosilica addition. Nanosilica was synthesized from rice husks and characterized using particle size analysis and scanning electron microscopy. Data were analyzed with Shapiro-Wilk test, Levene test, Welch t-test, and paired t-test.  Results: Characterization results showed nanosilica particles in the nanoscale range with two main distribution peaks and amorphous, spherical morphology with agglomeration tendency. L* values increased significantly, whereas changes in a* and b* values showed no significant differences.  Conclusion: These findings indicate that adding 0.5% rice husk nanosilica to the opaque layer increases brightness and total color change in metal-ceramic crowns, requiring esthetic control in its application.
