Abstract

Microorganisms such as Escherichia coli in water are a component that is difficult to remove in conventional water treatment systems. Several systems have been implemented to reduce levels of microorganisms is the use of disinfectants, the membrane filtration and activated carbon absorption. These systems have several weaknesses, so that not all microorganisms can be removed from drinking water. The plasma system is an applicable technology for removing organic compounds and microorganisms in drinking water. By creating plasma in water will produce several of active species such as OH-, H+, O3 and H2O2 that has a high oxidation potential, decompose organic compounds and kill microorganisms in the water significantly. This paper will describe the removal of microorganisms in drinking water using a plasma system by the method of dielectric barrier discharge (DBD ). The results howed that the pH of drinking water produced in the range 6.5 to 7.3. The higher voltage causes the higher the conductivity, temperature and ORP water. Removal efficiency for the content of microorganisms Coli Fecal and Coliform in the range 99.2 to 100% after water was injected voltage of 13-17 kV for 10 minutes.

Abstract

This study examines the effect of Environmental, Social, and Governance (ESG) scores on financial risk and stock investment performance of issuers listed on the IDX ESG index over the period 2017 to 2023. Using a quantitative approach, this study applies panel data regression analysis to explore the relationship between ESG scores and financial risk and stock risk. The variables analyzed include ESG score, Return on Assets (ROA), leverage ratio, corporate assets, earnings per share and book value per share. The research findings show that ESG score has a significant negative effect on financial risk, which means that the higher the ESG score, the lower the financial risk faced by the company. However, its effect on stock risk is not significant. The practical implication of this study is the importance of improving the quality of ESG scores as a strategy to mitigate financial risk and increase firm value. This study makes an original contribution by focusing on Indonesia's emerging capital market and highlighting the role of governance aspects in risk management, thus enriching ESG literature in the context of emerging economies and supporting ESG policy development in Indonesia.

Abstract

This study analyzes the challenges of Business Continuity Management (BCM) for the banking sector, especially conventional commercial banks in facing various operational challenges. BCM serves as a framework to help minimize the impact of disruption on the banking sector in the face of risks such as natural disasters, pandemics, and cyberattacks. The methods used include Business Impact Analysis (BIA), development of recovery strategies, and implementation of sustainable mitigation measures with the implementation of the BETH3™ framework and international standards such as ISO 22301, so as to provide systematic guidance in identifying critical assets and designing integrated mitigation measures, which include building elements, equipment, technology, human resources, and third parties in the bank Conventional. The results of the study show that BCM not only allows the banking sector to survive and adapt to the crisis, but also accelerates operational recovery. With a focus on continuous improvement, the implementation of the BETH3™ framework in BCM can prepare the Bank to face challenges more prepared and adaptive. The need for stronger collaboration with external parties, such as regulators and technology providers, as well as the importance of regular training for employees to ensure readiness to deal with crisis situations. Thus, the banking sector can be better prepared to face challenges and maintain competitiveness in a dynamic market
