Abstract

Climate change threats to food security, because it decreases agricultural productivity. C. indica L can adapt to environment and produce white and red rhizomes. Dominant content both of rhizomes are carbohydrates which increase protein as nutrition by adding S platensis. The research aims to determine potential of composite flour of C. indica L and S. platensis as alternative healthy foodstuff for food security. The method consists of formulation composite flour, proximate tests, determining amino and fatty acids, in vitro growth tests of Lactobacillus, cookies and meatball formulations. The result showed composite flour from red rhizome (RRCS) contains 11% water, 21.745% protein, 0.5% lipid, 9.99% dietary fiber, 57.81% carbohydrates, and 8.94% ash.  While white rhizome (WRCS) contains, 8.75% water, 17.41 protein, 0.29% lipid, 9.54% dietary fiber, 67.601% carbohydrates and 5.94% ash. Amino and fatty acid appears in both composite flours were similar, except proline and oleic acid higher in RRCS.  Lignoceric founded only in WRCS. In vitro test showed Lactobacillus (BAL) grew on modified MRSA from RRCS and WRCS. Both of composite flour processed into marketable cookies and meatballs formulations. Based on the result, C. indica L and S. platensis composite flour can be used as alternative food for food security.

Abstract

Population increase has an impact on the procurement of food sources. Pakcoy is a vegetable that is in increasing demand. Farmers' response to this condition is to use excessive fertilizer and pesticides, thereby reducing soil fertility. The research aims to obtain a combination of fertilizer and humic acid, which is effective in cultivating B. rappa chinesis L., as well as soil conservation efforts. The methodology was experimental with Randomized Block Design (RBD) on four treatments, K, P1, P2, and P3. The dose of K was 150 g/5 m2, NPK 16:16:16, 1 kg/5 m2 dolomite, and 5 kg/5 m2 manure. The P1 treatment is the same as K but without NPK fertilizer. P2 and P3 treatments were reduced by 50% and 70% of NPK fertilizer, respectively, with the addition of humic acid. The research results show that P2 with local environmental conditions provides optimal results in terms of chlorophyll, stomata, and plant height. Soil fertility was shown by increasing pH to 6.6, K 281 ppm and P 509 ppm, Cation Exchange Capacity (CEC) 31.60 cmolc/kg, soil enzymes of 0.12 mg FDA g-1 soil d.w. h-1, an average number of earthworms of 17. The conclusion is that P2 fertilizer formulation can be applied to cultures as an anticipation of food security.
