Noncommunicable diseases (NCDs) are the major cause of mortality globally. Malnutrition and inadequate or excessive intake were associated with increased risk factors for NCD development. This study aimed to determine the organoleptic profile and nutritional value of biscuit food formula from local food based on soybean (Glycine max) flour, tempeh flour, and Moringa leaf powder. This study was conducted in Yogyakarta, a city located in Indonesia in Southeast Asia. The organoleptic test involved 36 semi-trained panellists who fulfilled the established standards. The organoleptic profile was evaluated for colour, taste, aroma, texture, aftertaste, and overall acceptability. Five biscuit formulas, including the control (F0) and four sample treatments with the addition of 0 g (F1), 2.5 g (F2), 5 g (F3), and 7.5 g of Moringa leaf powder, were tested. The ratio of soybean flour to tempeh flour was 5:2 without F0. Organoleptic properties were analysed using the Friedman test and the Wilcoxon test. The highest scores for organoleptic profile, including colour, taste, aroma, texture, aftertaste, and overall acceptability parameters, were observed in F2, which was added with 2.5 of g Moringa leaf powder, and scored 3.61 ±0.599, 3.47 ±0.654, 3.67 ±0.793, 4.06 ±0.475, 3.22 ±0.898, and 3.53 ±0.654 respectively. Selected biscuit formulation (F2) per 100 g contains 534.8 kcal of energy, 18.8 g of protein, 33.0 g of fat, 40.49 g of carbohydrate, and 18.08 g of dietary fibre.
