A rapid development of the concrete construction sector has resulted in an increase need for raw materials that are obtained directly from nature. The environmentally friendly is also increasing along with engineering technology, so several studies have been conducted to search alternative additives or mixtures. Anadara granosa clam shell can be utilized as one substitute material coarse aggreg...

Abstract The cockle immerses in the substrate of intertidal zone. Their conditions and growth factors are highly dependent on nutrients around waters Kendari Bay. Therefore, this study aims to determine relationship between length, weight, condition factors. was conducted March 2016 February 2017 at zone samples were collected with a shovel 1x1 m square transect monthly. Furthermore, length wei...

Penelitian ini bertujuan untuk mengetahui kerang (Anadara granosa) di TPI Tambak Lorok, Semarang. Metode penelitian digunakan adalah deskriptif kualitatif. Sampel diamb...

This study aims to determine the levels of heavy metals (Cd) and (Pb) in shellfishes mangroves at Bima bay. The results showed that bivalves mangrove tissue were analyzed for metal content form lead (Pb), Cadmium using an Atomic Absorption Spectrophotometer. From analysis, it indicates 3 species Shellfish which different results; Blood shells (Anadaragranosa) 0.756 ppm, Hiatula (Hiatula chinens...

The present study describes the synthesis and characterization of a hydroxyapatite (HAp)-based adsorbent derived from biogenic cockle (Anadara granosa) shells for defluoridation drinking water. raw synthesized HAp were characterized by X-ray fluorescence spectroscopy (XRF), attenuated total reflection-Fourier transform infrared (ATR-FTIR), diffraction (XRD), Field emission scanning electron mic...
