Abstract

Coconut milk is a thick white liquid extracted from coconut produced from shredded coconut and then squeezed with water. Coconut milk is an ingredient produced from processed old coconut. Coconut milk can be used as food preparations or as herbal beauty ingredients. One of the advantages of coconut milk in the field of beauty is that it is very effective as a dandruff remover. By using old coconut milk as a dandruff remover we can get amazing results with natural ingredients without spending a lot of money. Coconut milk has many contents such as water content, protein and fat which are quite high as well as cow's milk. Coconut milk is rich in vitamins C, B, B-6, thiamine, niacin, folate, a number of minerals (calcium, magnesium, iron and phosphorus). Pure coconut milk only contains 54 percent water, 35 percent fat and 11 percent nonfat solids (approximately 6 percent carbohydrates, less than 4 percent protein and other solids) which are categorized as emulsions of oil in water. Coconut milk is known to be effective in eliminating dandruff, because coconut milk contains coconut oil containing Vitramin E and fatty acids that can eliminate and eradicate dandruff. You do this by using coconut oil as a massage oil to massage the scalp.

Abstract

Plastic is one of human needs in daily life, one of which is as a place for wrapping food and drinks, because plastic is practical, clean, and very easy to meet human needs. Increasing the level of public consumption of plastic will also increase the waste / waste produced. The waste has now become a serious environmental problem because of the increasing amount of plastic waste that exists and the level of danger that can be generated from plastic waste for other living things. In Indonesia, the demand for plastic continues to increase until it increases an average of 200 tons per year. As a result of the increased use of plastic is also increasing plastic waste. From testing utilizing existing plastic waste as mentioned above, shows a comparison that is not much different from kerosene traded on the market both in terms of color, thickness, and combustion process. it is known that polyethylene (PE) plastic with a mass of 500 grams can produce as much as 400 ml kerosene in 30 minutes.

Abstract

Acidic battery electrolytes, thus fruits that are acidic and contain lots of KCl can be used as an alternative to Citrus or orange electrolytes is one type of fruit that is famous for its acidity because it contains a lot of citric acids (C6H8O7). Oranges also contain calcium, phosphorus, and iron. Another advantage of citrus fruit is its abundant availability, and the waste of orange peel also has acid content, which can also be used as a bio-battery material. It concluded that lime could flow electric current because it contains chemicals such as citric acid, amino acids, glycosides, and calcium: phosphorus. Lime is a lot of ingredients and benefits that are useful for our health. Besides, lime contains chemical elements. Chemical elements found in lime can produce an electric current because it contains citric acid, amino acids, glycosides, phosphorus, etc. Thus, the lime can turn on the lights after being connected in series.

Abstract

Plant of Muntingia calabura L are often known as kersen, seri or cherry. Leaves of Muntingia calabura L. contains many benefits but its properties are still little known to the public. It contains secondary metabolites which have many uses. This study was aimed to determine the content of secondary metabolites in this leaf. Leaves extracts were obtained by maceration extraction for 3 times 24 hours using polar, semi-polar and non-polar solvents to determine the solubility of secondary metabolite compounds in each solvent. The solvents used were ethanol, ethyl acetate and n-hexane. The leaveswere dissolved a lot in polar solvents, marked by the formation of a dark green color in ethanol-series extracts, the color fades more in semi-polar and non-polar solvents. The three leaves extracts were tested for secondary metabolite contents by phytochemical screening tests. Phytochemical screening was an initial selection stage to detect classes of chemical compounds contained in plant. Phytochemical screening were included alkaloid, terpenoid, steroid, tannin, flavonoidand saponin tests. Based on the results of phytochemical screening tests, the leaf was contained several secondary metabolite compounds, namely flavonoids, saponins, steroids, terpenoids, alkaloids, phenols and tannins.

Abstract

Corrosion or rusting is very common in metals is a decrease in the ability of a metal due to the environment or chemicals. Sea water is a corrosive environment for metals because it contains sodium chloride (NaCl), calcium sulfate (CaSO4), calcium carbonate (CaCO3), and dissolved oxygen (O2) which affect the corrosion process of the material. The presence of dissolved oxygen will cause the rate of corrosion in metals to increase with increasing oxygen content (O2), the solubility of oxygen in water is a function of pressure, temperature and chloride content. The process of corrosion is almost the same for all materials, especially in metals occurs slowly but surely, corrosion can cause a material to have a limited service life, where the material expected to be used for a long time turns out to have a shorter life span than the average usage life.

Abstract

Metals react with acid to produce hydrogen gas. Some of floor cleaner liquids contain concentrated strong acid such as HCl. This study was conducted to react metals (Zn, Al, Fe, Cu) with floor cleaner liquids (WPC and Vixal) that contain 17% HCl to produce hydrogen gas. The most hydrogen gases were resulted from reaction between Al and both of floor cleaner liquids. They show the same trend Al lebih besar dari Cu lebih besar dari Zn lebih besar dari Fe for the volume of hydrogen gas produced . It was not appropriate with theory due to different of surface area of each metals used.

Abstract

Along with the development of science and technology, more and more types of manufactured goods produced to meet our needs we need to know that among these materials there are dangerous or toxic, therefore it is very important for us to know the type, nature, usefulness, as well as the dangers of every chemical that we use at home As we know, all kinds of objects that are around us are actual material, all material consists of chemicals but, in our daily lives we commonly use the term material instead of chemicals. Clothing that we use every day will be prone to stains so it is important to know how to remove stubborn stains on clothes. It would be very inconvenient if the clothes worn are dirty and not beautiful to the eye. There are many types of stains, ranging from dirty sweat, blood, residual makeup, black spots caused by fungus, to stains from the outside such as stains caused by rust, paint, oil, ink or spills of food and drinks. If you use the wrong method to remove these stains, it is not uncommon for us to find difficulties and can even be fatal as they get dirty. Each type of stain has a different treatment, depending on the nature of the stain. Bleach is now available as a solution to the problem of stains on these clothes.
