VALIDASI METODE ANALISA KADAR AIR DAN KADAR Ca PADA PENGUJIAN GARAM

Abstract

Salt is an essential component of human life. In addition to being a basic food necessity in Indonesia, salt is also used as a raw material in various industries, such as fertilizer production and mining. This study aims to validate the analytical methods used to determine the moisture content and calcium (Ca) levels in salt testing at PT X. Moisture content was determined using the oven (gravimetric) method, while calcium content was analyzed using Atomic Absorption Spectrophotometry (AAS). The test results were compared with the threshold values set by the Indonesian National Standard (SNI). The moisture content in raw salt sample number 5 was found to meet the SNI standard, with a value of 5.3%. Meanwhile, the calcium content in processed salt showed an average value of 0.05%, indicating that the sample is considered safe and compliant with the established standards.
