Anchovy is a common fish found in all over Indonesia's sea. Anchovy, often stated, that it has high fluoride content as well as other ocean fishes, but to date there are limited study measuring the fluoride content in anchovy (Stolephorus insularis) established yet. The aim of this study is to measure fluoride content in Stolephorus insularis using Ion Selective Electrode (ISE). To measure fluoride ion with ISE, sample preparation was needed to obtain maximum fluoride readability. Sample preparation consisted of heating, shaking, digesting, and ashing. Samples were divided into two groups, one was heated using the oven at 800 for 5 minutes (oven group), and the other group was left fresh (non-oven group). The prepared samples were then measured with ISE. The results found that the fluoride concentration of non-oven and oven Stolephorus insularis ranged from 12.935 - 13.381 ppm and 15.416 - 24.914 ppm, respectively. It is concluded that ovened Stolephorus insularis has potential to be a natural source of fluoride.
