Abstract

This study aims to analyze and empirically test the influence of leadership on the performance of the Medan City Manpower Office. The Manpower Office plays a crucial role in administering government affairs in the employment sector, which directly impacts public welfare and the investment climate in Medan City. Therefore, optimal performance is essential, one of which is strongly suspected to be influenced by leadership quality. This study uses a quantitative approach by distributing questionnaires to employees of the Medan City Manpower Office as a sample. The collected data are analyzed using simple or multiple linear regression methods (adjust to your design, for example: multiple linear regression analysis) to measure the contribution of leadership variables to performance variables. The results of this study are expected to provide empirical evidence regarding the significance of leadership's influence on increasing the effectiveness and efficiency of the office's work, as well as provide practical recommendations for the Medan City Government in its efforts to improve leadership quality within the bureaucracy, particularly in the Manpower Office.

Abstract

The spread of Islam on Sumatra Island originated in coastal regions before expanding into the hinterlands. Utilizing a historical approach, this study reveals that maritime trade routes served as the gateway for traders and missionaries from Arabia, Persia, and Gujarat to engage in commerce and dawah across Sumatra. Islam initially flourished in Barus, Samudera Pasai, and Aceh before eventually expanding into the interior through river networks, intermarriage, and the political influence of the sultanates. The findings of this study indicate that the process of Islamization in Sumatra was not uniform; in coastal areas, Islam tended to be more Cosmopolitan, whereas in the interior, cultural acculturation with local traditions occurred. The success of this expansion marked the starting point of a religious transformation across the Indonesian archipelago
