The Associations of Spirituality, Adversity Quotient and Ethical Decision Making of Accounting Managers in the Contexts of Financial Management and Corporate Social Responsibility. The aim is to provide a snapshot of some of the most exciting work published in the various research areas of the journal. This feasibility study aims to assess the potential of implementing a micro hydro system in Lalumpe Village, located in North Sulawesi, Indonesia. This research paper aims to conduct a feasibility study of a proposed micro hydro system in Lalumpe Village, located in North Sulawesi, Indonesia. The feasibility study assesses the technical, economic, and environmental aspects of the proposed micro hydro system to determine its viability as a sustainable energy solution for the village. Drawing on these insights, this study aims to provide a holistic understanding of the feasibility of micro hydro in Lalumpe Village and contribute to sustainable energy development in rural areas of North Sulawesi, Indonesia.
