The development of STEAM-based Google Sites learning media on the topic of energy transformation for fourth-grade elementary school students at SDN 32 Talang Kelapa aims to determine the development procedure, validity level, and practicality of the learning media. This study uses the Research and Development (R&D) method with a modified ADDIE development model consisting of only four stages: A…
This study analyzes the thermal efficiency of the Heat Recovery Steam Generator (HRSG) at the Keramasan Combined Cycle Power Plant (CCPP) in Palembang, Indonesia. Field data were collected at three operating times (08:00, 16:00, and 24:00) to evaluate HRSG performance using mass and energy balance. Calculations were based on temperature, pressure, and mass flow rate parameters of both working f…
This book contains steam tables for practical industrial use calculated by using the international standard IAPWS-IF97 for the thermodynamic properties of water and steam and the IAPWS industrial standards for transport and other properties. The complete set of equations of IAPWS-IF97 is presented including all supplementary backward equations adopted by IAPWS for fast calculations of heat cycl…
