World bodies have claimed the livestock industry as one of the contributors to the increase in pollution. This is a factor that needs attention. Waste from the livestock industry could be a trigger for this statement. The hatchery industry is one of the livestock industries contributing to pollution worldwide. One of them is eggshell waste produced from broiler egg-hatching activities. This study aimed to examine the properties of hydroxyapatite (HAp) from broiler eggshell waste from the hatchery industry. A total of 6 temperature variations were applied (550°C, 600°C, 650°C, 700°C, 750°C and 800°C). Applying different sintering temperatures produces different physicochemical properties of HAp, especially those using broiler eggshell waste as raw material. Applying a sintering temperature of 550ºC significantly increases the yield (Y) value and reduces mass loss (ML). Crystal formation and functional properties were not significantly different between different sintering temperatures. An application temperature of 550ºC is considered appropriate for HAp production efficiency. Utilizing broiler eggshell waste as a raw material for hydroxyapatite is essential in providing hydroxyapatite products that are easy to obtain, cheap, and environmentally friendly.
