Abstract

Housing is a fundamental human need that requires to offer its occupants the best possible safety and comfort. The Gianyar district of Bali is now home to a disproportionate number of structures of the Bali architectural style. The thermal comfort of modern Bali buildings is the subject of the bare minimum research, which makes it crucial to determine the thermal comfort of these structures as a foundational knowledge and point of reference for thermal studies of comparable structures. Using Autodesk Ecotect Analysis 2011 software, the research was conducted by modeling spatial convenience and presenting quantitative descriptive data through data tabulation and graphics. The study's findings demonstrated that the Bali Contemporary Building Study facility in Mas Village, Gianyar, had thermal comfort levels that exceeded Indonesia's norms.

Abstract

The Bili-Bili Reservoir serves multiple purposes, including flood control, raw water supply, irrigation, and hydropower generation. In 2021, significant discrepancies were observed between the Annual Reservoir Operation Plan (AROP) and the actual Reservoir Operation Pattern (ROP). during the first 15 days of December 2021, the AROP targeted a rest water level (RWL) of +77.34 m with a planned discharge of 20.27 m³/sec. In contrast, the realized RWL reached +92.35 m with an actual discharge of 45 m³/sec. This study aims to analyze the causes of these differences and compare the reservoir operations outlined in the AROP with those reflected in actual utilization, using an operational pattern simulation based on variations in irrigation water requirement (IWR). Analysis using a dependable flow of 80% shows that the total IWR in the AROP is only 69% of the IWR calculated from actual reservoir utilization, likely due to declining inflow trends and an operational pattern that adjusts to inflow magnitude and rainfall. Meanwhile, the realized IWR is 32% greater than the utilization analysis and 91% greater than the AROP, indicating that the reservoir released more water than planned, following actual inflow conditions. This study highlights the need for more adaptive reservoir operation planning to ensure effective water resource management.
