This study was aimed to analyze the nutrients content, antioxidant activity, and acceptance of the biscuit formula of Belitung taro (Xanthosoma sagittifolium) with various parts of ant nest tubers (Hydnophytum formicarum) plant. Antioxidant activity was found by the DPPH method, nutrient content by the AOAC method, and sensory evaluation analysis by 30 untrained panelists. The results of this study found out that each biscuit formula (35.25 grams/73.60% antioxidant activity) contained 130 kcal of energy, carbohydrates of 59.08 ±0.16%, the protein of 4.13 ±0.06%, fat of 22.17 ±0.19% so that it was able to compensate for 5.97 – 6.57% of total energy requirements based on the Nutrition Adequacy Rate for the Elderly per day. The overall preference level in the biscuit formula by untrained panelists was 4.10 ±0.72 (rather like-like). The addition of 7.5% ant nest tuber powder in the biscuit formula had an antioxidant activity (DPPH) of 73.60 ±0.36%. The most preferred biscuit formula was the C013 biscuit formula (addition of 6% ant nest tuber powder per gram biscuits), with the higher antioxidant activity, and its nutrient content to compensate for the nutrition adequacy rate for the elderly per day.
