As an effort to improve people's food and nutrition by using local food consumption methods and using appropriate technology. This study aims to assess the content of macronutrients and iron minerals through snack bar products. The research was conducted by formulating snack bars with the main ingredients of snakehead fish flour and peanuts at a ratio of 50:50, 60:40 and 40:60. Organoleptic tests and laboratory tests were carried out. The snack bar formula with the highest level of preference was the F3 snack bar (40:60) with an energy content of 409.03 kcal, 20 gr protein, 11.99 gr fat, 55.28 gr carbohydrates, 10.75% moisture content, 1.98% ash content and iron (Fe ) 0.94 gr. There are significant differences in the nutritional value indicators. Further research is needed to determine the right formulation with rich nutrient content and preferred product.
