documents and related research project to study the properties of the ink from printed fabric color extracts from gumbo, a study was made of the documents related to the project. As follows : 1. Roselle 2. Distilled water, urea 3. 4. Sodium Bicarbonate 5. Alginate cotton 6. 7. Measure the absorbance (UV-VIS Spectrophotometer) 8. Viscosity measurements (Brookfiled) 1. Roselle (Roselle) Figure 1 Roselle 1.1. Biological classification Kingdom: Plants. (Plantae) Division: Magnoliophyta Class: Magnoliopsida Rating: Malvales Family: Malvaceae Genus: Hibiscus species: H. sabdariffa binomial name: Hibiscus sabdariffa L. is a small shrub, about 3-6 feet from stem color. Violet There are many different types of leaves, sometimes jagged edges smooth concave 3 notches of color is pink. The flowers are dark in the middle and outer edges of the petals. When the flowers fade flower petals and sepals are growing up as a purple-red seed inside. Propagation is by seeds planted. Should be planted in the rain The soil before planting Dig planting holes 2-3 seeds to sprout and grow. To withdraw from the weaker to the stronger the trees, soil, watering, fertilizing, weeding out. Were parts Used for medicine and food is sepals and petals of flowers with a red pigment in the Anthony Saiyan. (Anthocyanin), which is soluble in water 1.2. Ingredients in Roselle substance that is found flavonoid compounds called crysanthemin, delphinidin -3-O sambubioside, myricetin, hibiscitrin, gossypitrin, the phenylpropanoid name ortho-coumaric acid, para-coumaric acid, ferulic acid, found that extracts from gumbo. with antioxidant activity (Antioxidant) and with anti-tumor liver and prostate cancer. A diuretic Lower Blood Pressure Reduce blood cholesterol Lower blood sugar And kill bacteria, especially gram-positive bacteria (Gram positive bacteria) is able to kill bacteria in the mouth and reduces fever 2. Distilled Figure 2 water is pure water. Because of the evaporation and condensation of water out. Distilled water to clean the dirt is visible and has a neutral pH or acidity light. With low conductivity Which is the proper manner of pure water is eliminated almost all the dirt in the refining process, namely the refining process is to boil water until the water evaporates and condenses into water droplets. Without the elements of water, DI (Deionized water) may also contain impurities, but distilled water is very pure because almost all impurities have been removed in the refining process. The water is a relatively slow process of production. To get a truly pure distilled water was used as a rental. Industrial and laboratory tests to clear the exchange ion batteries in laser cutting and so on. Distilled water is mainly used in the laboratory for experiments that require pure water and is also used in industrial processes that will contain impurities or contaminants to a minimum. Deionized water (water DI) water is water that is affordable for laboratory and industrial applications DI water is widely used. Batteries used in the automotive industry. The composition of the elements found in DI water may cause the lifetime of the battery decreases. Aquaculture and high prices. Always use distilled water with no elemental composition to reduce the risk of harm to the fish. There were also used distilled water instead of tap water in a steam iron. The water supply will cause the accumulation of trace elements in the iron and make it impossible. Steaming is distilled water should be stored at room temperature between 20 - 30 degrees Celsius, keep away from sunlight and moisture. It should be kept in a sealed container. Avoid excessive heat and cold. When enabled distilled water Water will begin to receive nutrients and contaminants in the atmosphere. This will affect the conductivity in particular. Getting gas carbon dioxide from the atmosphere Distilled water should be stored in sealed containers as possible factors which indicate the purity of the water. Conductivity The low conductivity shows the contamination in the water can be broken down into ions with a small amount. This value is used to assess the amount of impurities in the water rough. Present a measurement of the conductor that is easy and convenient 3. Urea (Urea) Fig. 3 urea physical and chemical properties common chemical name: Carbamide other synonyms: Carbonyl diamine; Carbamimidic acid; Isourea; Aquadrate; Ureaphil; Ureophil; Aquacare / HP; Nutriplus; Urecare; Urederm; Formula : structural formula: Status: solid powder Color: white Odor: ammonia diluted Molecular Weight: 60.16 melting / freezing point (C): 132-135 Gravity (water = 1): 1.335 acidity - alkalinity (pH): 5.6-7.5. at 25 ° C Factor Converter 1 ppm = 2.46 mg / cubic meter or 1 mg / cubic meter = 0.406 ppm at 25 degrees Celsius, physical and other chemical substance is soluble in ethanol. Geographical And methanol Stability and reactivity (Stability and Reaction) - Chemical Stability: This material is stable - substances that are incompatible substance oxidized - chemicals hazardous decomposition. : carbon monoxide Ammonia, carbon dioxide and nitrogen oxide - danger of Polymer Reaction: unrealized harmful to health (Health Effect) inhalation - inhalation may cause respiratory irritation. Harmful skin contact - contact with the skin can cause irritation to skin or swallowed - swallowing or swallowed causing nausea, vomiting, harmful eyes - the eyes will cause irritation. irritation retention / storage / transport / logistics (Storage and Handling) - Store in a cool, dry place - in areas with adequate ventilation - Keep away from substances that are incompatible, sparks and flame. Fire - storage at temperatures below 3 ° C at atmospheric pressure Marcel environmental impact. (Environmental Impacts) - Do not allow to enter waters or soil - this material is expected to readily biodegradable as well.
