Abstract

This study explores the application of green hydrogen technology for industrial decarbonization, focusing on its techno-economic and environmental feasibility. A quantitative approach was used, incorporating system modeling of a solar-based hydrogen production system combined with electrolyzers. The techno-economic assessment involved calculating the Levelized Cost of Hydrogen (LCOH), estimating capital and operational expenditures (CAPEX and OPEX), and evaluating the system's energy efficiency and hydrogen output. The environmental impact was analyzed using Life Cycle Assessment (LCA), comparing the carbon footprint of green hydrogen with fossil-based hydrogen. The results reveal that green hydrogen can reduce carbon emissions by up to 60% compared to fossil hydrogen, primarily due to the use of renewable energy for production. Additionally, the study found significant improvements in energy efficiency as electrolyzer performance and solar capacity increased. The LCOH is expected to decrease steadily as solar panel and electrolyzer prices continue to fall, enhancing the competitiveness of green hydrogen in the energy market. The findings also highlight the potential for heavy industries, such as cement and steel production, to transition from fossil fuels to green hydrogen, contributing to a cleaner industrial energy mix. This transition presents both environmental and economic benefits, with long-term savings from reduced fossil fuel dependency and lower production costs.

Abstract

This study examines the impact of personality and work engagement on Organizational Citizenship Behavior (OCB), with work motivation serving as a mediating variable, among inpatient nurses at South Jakarta Type B Hospital. OCB is crucial for enhancing organizational performance and service quality, especially in healthcare settings, where nurses' extra-role behaviors significantly contribute to patient care. The research utilized a quantitative approach with a survey design, involving 143 nurses from infection and critical inpatient wards. Data were collected through structured questionnaires and analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS). The results indicate that personality positively influences both work motivation and OCB. Work engagement also positively impacts work motivation and OCB. Additionally, work motivation significantly affects OCB and partially mediates the relationship between personality, work engagement, and OCB. These findings suggest that fostering nurses' work engagement and motivation, supported by positive personality traits, can enhance OCB, leading to better organizational performance and improved healthcare service quality.
