    New normal routines have continued to campaign since the COVID-19 pandemic broke out in 2019. One of these new habits is to keep washing your hands after every activity. Hand washing can be done using hand sanitizer or soap and washed in running water. As a result, the need for water to meet the habit of washing hands is expected to affect domestic water needs in a certain area. Therefore, this study aims to estimate the increase in domestic water demand during the COVID-19 pandemic caused by the new routine of washing hands in the research area in the city of Banda Aceh, Indonesia. In addition, this study will also estimate domestic water needs until 2030 if the COVID-19 pandemic has not ended. Innovations in this research can help increase efficiency in water use and help prevent the spread of disease. This study uses a sampling method in several places in Banda Aceh city to obtain data related to the volumetric water used, handwashing time, and frequency of handwashing. Besides, data in water discharge from water supply companies in Banda Aceh city from 2018 to 2020 was also collected. Finally, data on the population of Banda Aceh city was also collected. The information and data are then analyzed using a statistical approach between supply and demand. Although it appears that there is a projected increase in domestic water demand of 1.89% per year due to the COVID-19 pandemic from 2021 to 2030, this is still 41.48% greater than the ability of water supply companies in the city of Banda Aceh to meet domestic water needs up to 2030. In conclusion, if the pandemic continues until 2030, with the expected increase in population, the domestic water needs in Banda Aceh city will still be fulfilled.

    This study evaluated the drivers of environmental sustainability practices using mango farm managers in Thailand. The purpose was to ascertain farmers' ability to conserve natural resources and protect the ecosystem. This was necessitated to raise environmental awareness, promote sustainable human development, and increase economic growth and quality of life. The study adopted a quantitative survey design with primary data collected from mango farm managers in four provinces in Thailand. Data were collected from a total of 383 respondents. The data was analyzed using CFA and SEM techniques employing SPSS v26 and AMOS v26. The findings showed that Organizational Culture and Employee Training significantly and positively influence Environmental Sustainability Practices in managing mango as a natural resource. Organizational Culture was also found to positively mediate the effect of information system adoption. The study concluded that management and employees in mango farms should be trained about the importance of environmental sustainability and encouraged to cultivate a culture grounded in the sustainability practices of mango as a natural resource. They should be taught how advancing and adopting sustainable practices by subsistence and commercial mango farmers in Thailand can enhance sustainable development, economic growth, and regional cooperation by checking materials and methods.

    Development of heterogeneous catalysts particularly those derived from renewable resources is an interesting research topic. Various renewable resources such as animals, plants, natural materials, and industrial wastes are valuable resources for production of catalysts, supports, and materials for different applications including biodiesel production. For example, animal- and natural-based resources contain metal oxides with base properties suitable for catalyzing transesterification, while plant and industrial wastes contain high carbonaceous materials, which could be used as a catalyst support for both esterification and transesterification. This chapter summarizes heterogeneous catalysts derived from different renewable resources for biodiesel production with particular focuses on their preparation methods, physicochemical properties, and catalytic activities for biodiesel production. In addition, the advantages, disadvantages, and challenges of these types of catalyst in the biodiesel production are addressed.
