Vegetation resilience and environmental impact following industrial mud eruption: Spatial distribution analysis
Get PDFBackground: Hot mudflows from Lapindo Sidoarjo are often released consistently from cracks in the soil layer and begin to submerge the surrounding land cover, such as houses, school buildings, factories, agricultural land, and vegetation. Lapindo hot mud is hot volcanic mud that comes out due to cracks in the soil layer in Siring Village, Porong District, Sidoarjo Regency and has been researched to contain heavy metal compounds and high temperatures. This causes changes in vegetation biodiversity in the Lapindo mud region. This research aims to analyze the influence of the distance to the center of the Lapindo Sidoarjo mudflow on the physical characteristics of the environment and the spatial distribution of surrounding vegetation. Methods: The method used is the transect method for taking vegetation samples and snowball sampling for taking informants to support vegetation conditions in the research area. The observation and interview data obtained were then processed and analyzed quantitatively descriptively using multiple linear regression. Findings: The analysis carried out shows that the distance from the center of the burst does not have a significant influence on the distribution of air temperature and surface temperature. However, the distance from the center of the spray influences the acidity (pH) of the soil with an influence percentage of 41.2%. In statistical analysis, it was also proven that the physical characteristics of the Lapindo mud region did not affect the diversity of life form types. Apart from that, the analysis carried out in this research also produced six types of vegetation life forms consisting of herbs, bushes, trees, vines, epiphytes, and aquatic, which were distributed randomly throughout the research area in the form of the Lapindo muddy area. Conclusion: The existence of vegetation life forms is not determined by the physical characteristics of the Lapindo mud region but is influenced by the relative location characteristics, such as aquatic vegetation that grows due to the presence of water bodies and herbaceous vegetation that can grow on any open land. Novelty/Originality of this article: It can be concluded that the emergence of the Lapindo hot mud phenomenon in Sidoarjo only affects soil acidity. Moreover, this phenomenon does not have a significant influence on the spatial distribution of surrounding vegetation

The effect of dark triad leadership on emotional manipulation: The role of gender as moderator
Get PDFBackground: Emotional intelligence is vital in organizations, but it can also lead to negative behaviors like emotional manipulation. This manipulation is linked to dark triad leadership (narcissism, machiavellianism, and psychopathy) and gender differences. Previous studies have shown inconsistent findings on how emotional manipulation relates to these traits and the role of gender, with some suggesting men are more prone to emotional manipulation. Methods: This study tests the effects of narcissism, machiavellianism, and psychopathy on emotional manipulation and examines gender as a moderator. Participants included 216 individuals from various organizations in Indonesia who were over 18 and had subordinates. The study used the Short Dark Triad (SD3) and Emotional Manipulation Scale (EMS), with data analyzed through multiple linear regression and Hayes' regression model 1. Findings: The results showed that only machiavellianism and psychopathy significantly influenced emotional manipulation, while narcissism did not. Gender did not moderate the relationship between dark triad leadership and emotional manipulation. Conclusion: The study highlights that only certain dark triad traits contribute to emotional manipulation, and gender does not influence this relationship. Novelty/Originality of the Study: This research offers a clearer understanding of how specific dark triad traits influence emotional manipulation in the workplace, with gender playing no moderating role. It challenges previous assumptions about gender differences in emotional manipulation, providing new insights for leadership studies
