SUMMARY. Zainuddin et al., in their paper, carried out a redesign of the Indonesian railway executive chair with the added advantage of a chair that can be tilted up to 40° from the initial position of 10°. Paloboran et al., in their paper, determine the number of blades effect on a water turbine regarding flow rate and turbine rotation. Rean et al., in their paper, investigates the structural performance of a rescue boat crane mounting system on an LCT 153 vessel using finite element analysis. Yusuf et al., in their paper, design and evaluate a 40 kWp off‑grid centralized Solar Power Plant (SPP) to meet the electricity needs of two underserved villages on Insumbabi Island, Supiori Regency, Papua, Indonesia. Hanifah et al., in their paper, investigates the drying characteristics of wet Arabica coffee beans using an HPD system, focusing on determining the drying rate constant (k) at various inlet air temperatures and humidity conditions. Tambunan et al., in their paper, identify and evaluate the characteristics of various agricultural and plantation wastes to determine their feasibility as solid biomass energy feedstock. Anggrainy et al., in their paper, compare the performance of biogas from human feces with liquefied petroleum gas (LPG) as fuel for water pump engines. Wiradinata et al., in their paper, investigating the effects of single quenching and double quenching techniques on the mechanical properties of SKD 61 material, particularly in the context of bending strength and hardness measured using the Brinell hardness test. Kurniawan and Soegijono, in their paper, conducting comparative characterization of polyurethane-based composites with single and dual fillers—carbon and ZnO—prepared under identical conditions to evaluate their combined effect on thermal, dielectric, and surface properties. Buana et al., in their paper, evaluates the performance efficiency of horizontal-axis wind turbines equipped with two blade types: taper and taperless, both using the NACA 0012 airfoil.
