Abstract

Lumpy Skin Disease (LSD) is caused by the Lumpy Skin Disease Virus (LSDV) that affects cattle and buffalo. The symptoms include the development of lumps or nodules on the skin of infected animals. Therefore, this study aimed to detect the presence of LSD and determine factors associated with the incidence in cattle transhipped through Merak Port. Samples were collected in the form of oral and nasal swabs, then tested with quantitative real-time PCR (qPCR). The results showed that there were two positive LSD samples confirmed by molecular testing using qPCR. The positive cattle did not show clinical signs or were suspected to be sub-clinically infected, while the Ct values obtained were 27.71 and 28.88. The use of molecular methods with qPCR showed relatively good results for the detection of LSD. Cattle that did not show clinical signs were detected as positive by the test. This is because qPCR can detect viruses more quickly and accurately, even at very low viral load levels. Factors associated with the incidence of LSD in the Merak Port (p < 0.05) were farm origin and biosecurity measures, knowledge of livestock handlers, vaccination status, and disinfection practices.

Abstract

This study explores the influence of transactional and transformational leadership on organizational effectiveness, with organizational culture serving as a mediating variable, aiming to examine how leadership styles shape culture and subsequently impact effectiveness, particularly within public sector institutions. It offers a novel contribution by emphasizing the mediating role of organizational culture in the relationship between leadership styles and organizational effectiveness—an area that has been inconsistently addressed in previous research. By focusing on a governmental office (Office X), the study provides contextual insights into leadership dynamics in public administration. The findings reveal that transactional leadership has a positive and significant effect on organizational culture, which in turn enhances organizational effectiveness. In contrast, transformational leadership, while positively correlated with organizational effectiveness, does not significantly influence organizational culture directly. Furthermore, organizational culture significantly mediates the relationship between transactional leadership and organizational effectiveness, but this mediating role is not supported in the case of transformational leadership. The study concludes that transactional leadership is more effective within established organizational cultures, whereas transformational leadership is better suited to innovative and collaborative environments. Thus, organizational culture is crucial in enhancing leadership effectiveness, and future research should consider additional mediating factors such as employee motivation and job satisfaction.
