Kimpul can be used as various types of products to increase added value, one of that is biscuits. The advantages of biscuits include long-lasting, also easy to digest. Therefore biscuits can be made as complementary foods for ASI (MP-ASI). MP-ASI biscuits are commonly consumed by children aged 12-24 months. MP-ASI biscuits with the raw material of kimpul flour still need other ingredients to increase the protein content in order to meet the quality requirements, such as cowpea flour. To improve the texture to make it softer, it is used sago flour. Sago flour, which has a high starch content, also functions as an adhesive. This study aimed to determine the quality of the MP-ASI biscuit product of kimpul-cowpea composite flour and sago flour during storage. The research used a single factor RAK, namely the type of packaging (PE pouch, aluminum foil pouch, PE-aluminum foil pouch) and repeated three times. Observation during storage was done in every two weeks for six months. The parameters taken were physical characteristics, water content, Aw, FFA, TPC, and peroxide number. The results showed that during storage, there was a decrease in the quality of physical characteristics, increased water content, Aw, FFA, peroxide number, and TPC.

Wet noodle is a food product that is liked by all levels of society. The main ingredient for making wet noodle is wheat flour which must be imported from other countries. For this reason, it is necessary to look for other alternative raw materials, namely kimpul flour. Red dragon fruit can be used to increase nutritional value because it contains antioxidant and improves product appearance because it contains natural dyes. The purpose of the study was to determine the effect of the proportion of wheat and kimpul flours, as well as the concentration of dragon fruit on the quality of dragon fruit wet noodle. This study used a factorial randomized block design (RBD) with the first factor being the proportion of wheat flour and kimpul flour (T1 = 40%:60%, T2 = 50%:50% and T3 = 60%:40%) and the second factor was dragon fruit concentration (N1 = 20% and N2 = 30%) with 3 replications. The results showed that the proportion of wheat flour and kimpul flour had a significant effect on protein content, elasticity, and organoleptic tests. While the concentration of dragon fruit significantly affected the water content, carbohydrate content, elasticity, and organoleptic tests. The conclusion of this research was the treatment of T3N2 (proportion of wheat flour and kimpul flour 60%: 40% and dragon fruit concentration 30%) became the selected treatment with parameters of water content 48.51%, ash content 1.72%, protein content 6 0.04%, fat content 2.64%, carbohydrate content 41.09%, and elasticity of 0.39, and has a total preference percentage of 100% color, 96.7% aroma, 100.0% taste and 96.7% texture.
