  Temulawak (Curcuma xanthorrhiza roxb) is a medicinal plant of the Zingiberaceae family. It grows in Indonesia and is used as a raw material for Indonesian traditional medicine. Temulawak is known to have many benefits, including being a potential antioxidant. The active component that is responsible for antioxidant activity in temulawak is curcumin. This study aims to analyze the potential of temulawak rhizome as an antioxidant. The raw materials used were obtained from temulawak rhizome farmers in Purworejo, Central Java. Extraction was performed using the liquid-liquid extraction method developed by PT Javaplant. Proximate analysis was performed and the antioxidant properties and curcumin level were measured. The antioxidant properties were measured using the DPPH method, whereas curcumin levels were measured using HPLC. The data obtained were processed and analyzed using SPSS and presented in the descriptive form. The curcumin and yield contents of the sample were 27.19 and 1.02%, respectively. The antioxidant capacity of temulawak (IC50) was 87.01 ppm. The Temulawak extract exhibited antioxidant activity that was classified as active and is therefore considered to be a good natural antioxidant.

  Background and Objective: Breast milk is able to meet the needs of a baby only until the baby reach 6 months of age. After that, the milk production decreases in the mother, while the baby’s needs increase with the baby’s age and weight. This study aimed to determine a formula for instant baby porridge as a complementary food to breast milk, in which snakehead fish meal and pumpkin flour are substituted due to their organoleptic characteristic properties. Materials and Methods: Ingredients used in this instant baby porridge are gelatinized corn flour, powdered milk, snakehead fish meal, pumpkin flour, refined sugar and palm oil. The processing of instant baby porridge with snakehead fish meal and pumpkin flour was done by using the dry mixing method. The average results of organoleptic testing were based on the color, texture and taste of the porridge and data were analyzed using a t-test. Results: The results showed that the best formula for its color was formula A, 6.3 (slightly yellow); for its scent, formula A, 5.0 (rather strong smell of fish and pumpkin); for its texture, formula A, 5.0 (rather smooth) and for its flavor, formulas C and D 4.8 (sweetish). Conclusion: It can be concluded that the best formula of instant baby porridge as a complementary food to breast milk, based on its organoleptic characteristic properties, is formula A, comprising 15% snakehead fish meal and 10% pumpkin flour.
