Fish bone waste has long been used in research laboratories and it is unfortunate that still many
communities fail to understand its importance that makes it necessary for the program to transfer
knowledge to the community inorder to improve its usefulness. The technology of processing
fish bone that has been transferred to the community was to utilize the fish bone waste into the
various needs of the community. The program is seen as having the capability to improve the
community environment and contribute to community development policy, projects and research
in social engineering. Fish bone is a form of waste generated from the fish crackers processing
industries that contain the highest content of calcium. In terms of food and nutrition, fish bones
are rich in calcium, phosphorus and carbonate needed by human. Involvement of the community
to use leftover fish bone to produce hydroxyapatite is a way to improve society and reduce
pollution. In addition, hydroxyapatite can also be used as a bone replacement implants, heart
valves, hip extension and other implants in the human body.
