Calcium functions for the body's metabolism in the bone and tooth<br>formation. Petek and Mujair fish contain calcium that is needed by the human body.<br>The purpose of this study was to determine the levels of calcium contained in Petek and<br>Mujair fish.<br>The sampling was done by purposive sampling, which the sample used was obtained by the<br>market in the Peunayong Banda Aceh. This research used complexometry methods. The<br>samples of Petek and Mujair fish that had been cleared were titrated using Na2-EDTA as the<br>titrator.<br>The result showed that Petek and Mujair fish had different calcium levels where the calcium<br>levels in Petek fish reach an average of 0.853% and the calcium levels in Mujair fish reach<br>an average of 0.616%. Petek fish had higher calcium levels than Mujair fish, it was caused<br>by their habit, where Petek fish was sea fish that contained fat, vitamins and minerals, while<br>Mujair fish was freshwater fish that contained carbohydrates and proteins.</p> ER -
