Valorisasi Cangkang Kerang Kijing (Pilsbryoconcha sp.) Menjadi Hidroksiapatit…

ABSTRACT The freshwater of mussel shell (Pilsbryoconcha sp.) are a solid waste that is underutilized in Riau Province. Even though the fresh water of mussel shells are composed of high levels of calcium, the calcium content is 61.39%. So, there is a need for valorization that reduces solid waste.
