Abstract

Abstrcact Jamu Selokarang is one of the traditional drinks originating from an area, namely Madura, the ingredients used in the manufacture of Jamu Selokarang are turmeric, ginger, ginger, betel leaf, soursop leaves, cloves, nutmeg, coriander, temu ireng and ginger. The ingredients used in the manufacture of herbal medicine selokarang contain a lot of antioxidants and essential oils. Testing is needed to determine the antioxidant activity contained in the herbal medicine selokarang. This study aims to determine the effect of substitution of jamu selokarang on antioxidant compounds, total phenols, flavonoids, ash content and water content. This study used a simple completely randomized design method (simple CRD) with a single factor, namely the black cumin formulation of 0%, 2%, 4%, 6% and 8% which were included in jamu selokarang. The research was repeated 3 times. The parameters observed were: water content, ash content, antioxidants, total phenols, and flavonoids. The results showed that the substitution had a significant effect on water content, ash content and antioxidant activity, while the total phenol and flavonoid analysis had no significant effect. Treatment 0% black cumin had water content of 2.68%; Ash content of 7,90%; DPPH anti-oxidant for 49.08%; antioxidant FRAP 26.25 μgAAE / mL; total phenol was 2.05 μgGAE / mg, and total flavonoids was 0.91 μgQAE / mg.

Abstract

Indonesia is a country that has a high level of biscuit consumption. This is supported by many local food commodities. Therefore, many food products have emerged that use local food ingredients, such as bread, biscuits and cakes. One effort that can be made to enrich the nutritional content of biscuits is to add soybean flour which is rich in protein and flour of red dragon fruit peel which is rich in dietary fiber. The purpose of this study was to determine the effect of the ratio of wheat flour, soybean flour and red dragon fruit peel flour to chemical and organoleptic quality of biscuits. This research used a simple randomized block design with ratio of wheat flour, soybean flour, and red dragon fruit peel flour consisting of 10 levels: P0 (100%:0%:0%), P1 (80%:10%:10%), P2 (70%:20%:10%), P3 (60%:30%:10%), P4 (75%:10%:15%), P5 (65%:20%:15%), P6 (55%:30%:15%), P7 (70%:10%:20%), P8 (60%:20%:20%), P9 (50%:30%:20%). Each level is repeated 2 times. The parameters being observed were level of protein, fat, crude fiber, water, ash, and organoleptics (aroma, taste and texture). The results showed that the proportion of wheat flour, soybean flour and red dragon fruit peel flour had a very significant effect on level of water, protein, crude fiber, and organoleptic (taste, aroma, and texture). Treatment of biscuits with proportion of wheat flour 60%: 30% soybean flour: 10% red dragon fruit peel flour was the best treatment with level of water 6,58%, ash 0,76%, fat 27,95%, protein 9,74%, crude fiber 6,10%, organoleptic of taste 4,65 (delicious), aroma (rather tasty), and texture (rather not hard)

Abstract

Edible film is an organic material packaging that has plastic-like properties but is biodegradable. The components of the edible film include hydrocolloids. Okra gel is a long chain hydrocoloid polysaccharide with a high molecular weight and a constituent protein containing both hydrophilic and hydrophobic substances. The hydrophilic characteristics are used to improve the physical properties of solubility. Meanwhile, hydrophobic characteristics are used to improve barrier properties (WVTR). Okra (Abelmoschus esculentus L.) is one of the cultivated plants that is currently underutilized by the community but has benefits and high nutritional content. The addition of cassava starch aims to increase the strength of the edible film. The purpose of this study was to determine the use of okra gel proportion and cassava starch concentration in making edible films which can produce edible film characteristics that meet the standards.This study used a factorial randomized block design (RBD). The first factor is the ratio of okra gel and distilled water (1: 3; 1: 1; 3: 1, 1:0). The second factor is the concentration of cassava starch (2.5% and 5% (w / v)). The parameters tested were yield of raw materials, thickness, solubility, transparency, tensile strength, elongation, WVTR (Water Vapor Transmison Rate) and SEM (Scanning Electron Microscopy).The results showed that there was no interaction between okra gel and cassava starch. However, the comparison of okra gel and distilled water had a significant effect on the transparency value with an average of 0.89-1.60 A546 / mm. The concentration of cassava starch has a significant effect on transparency 0.89-1.60 A546 / mm, tensile strength 0.97-2.33%. Edible film with the best treatment was obtained in G2P1 treatment (ratio of okra gel and distilled water (1: 1) and 2.5% cassava starch) with a thickness of 0.08mm, transparency 0.58A546 / mm, WVTR 3.87g / m2 / 24h, elongation 9.24%, tensile strength 0.74MPa and solubility 23.56%. And SEM analysis results show uneven morphology.
