Abstract

The Map Banggai geology sheet especially Bunta has ultramafic rocks so it needs to be mapping the laterite nickel resources. This study aims to determine the spread, determine the levels of mineral elements contained and determine the estimated nickel laterite resource in the research area. The research method was carried out by taking field data and testing the sample levels then analyzed using the application of Geographic Information Systems (GIS). The results showed that the distribution of laterite nickel was found in the ultramafic unit area with elevations between 110 - 170 m which extended from north to south of the research area with an area of ​​29.25 ha, levels of Ni elements for Cut Off Grade (COG) were 1.6% and Fe 34.29% with a thickness of 3 m and an estimated nickel laterite (hypothetical) resource of 1,140,750 tons.

Abstract

This study examines the relationships between employee engagement, organizational culture, psychological empowerment, and employee performance within PT Tanjung Selatan Makmur Jaya. Employing a quantitative research framework, data was collected through a structured questionnaire administered to 152 employees selected via purposive sampling. The analysis employed the PLS-SEM technique, facilitated by SmartPLS software, to investigate the relationships among the variables. The findings suggest that employee engagement and organizational culture have a significantly positive impact on employee performance. Furthermore, employee engagement has a positive influence on psychological empowerment, which acts as a mediator in the relationship between organizational culture and employee performance. Conversely, psychological empowerment does not mediate the relationship between employee engagement and performance. This research highlights the crucial roles of employee engagement, organizational culture, and psychological empowerment in enhancing employee performance. It also elucidates the interactions among these factors, offering valuable insights for organizations seeking to develop more effective human resource management strategies that enhance employee performance in contemporary settings.
