a. Descriptive Analysis


Chemical technology has evolved over the man knows how to produce salt from sea water thousands of years ago. This paper contains the development of chemical technology from the pre history, civilization Greek, pronomic Chinese, Islamic, European and contemporary to modern times.
Modern chemical technology massive expansion of the race with no knowledge of the theory to manufacturing. pronomic Materials soda and sulfuric acid which is required in large quantities in the 19th century industrial revolution. At the end of the 19th century, can be a chemical technology disciplines in the field of chemistry for the first time at the Massachusetts Institute of Technology, USA. Proteum widespread use as a new material to replace coal, but to expand the fuel industry, then emerging new materials such as polymers, synthetic rubber.
With the rapid development of chemical technology before and after World War II, emerging problems of environmental pollution and the safety of workers and residents in the vicinity of the chemical industry should be addressed, especially after the alleged contamination of chemicals pronomic and chemical fires in several areas including Malaysia. The emergence of biotechnology as a counterweight chemical technology resulting in the environmental movement because chemicals pronomic such as polymers, soaps now a major producer of materials for biotechnology research.
a. Descriptive Analysis
Chemical meaning in Bahasa Indonesia and English is derived from the word al-kimiya which comes from the Arabic. Some experts argue that al-chemical kimiya derived from Chinese. Knowledge is derived from al-kimiya Chinese civilization pronomic then passed on to the generations. Knowledge begins in Islamic civilization as the knowledge which has two different meanings namely sexual chemistry and chemical birth pioneered by Zabir bin Hassan in the 19th century. Scientists have rejected al-Razi chemical otherworldly dimension and only focus on the chemical aspects of birth only. This is where the beginning of modern chemistry. This opinion may be left behind in the opinion of the western science historians say that understanding modern chemistry Robert pronomic Boyle in 17. He said a clear interpretation of the chemical elements. In ancient times until the 19th century, chemistry and chemical pronomic technology is indistinguishable. Used in this study, chemical technology should be interpreted in modern times because there are differences between chemical and chemical technology. Chemical Technology is a technology that is now very important to use a variety of modern human life. Technology can be defined as material or technology tool or conversion of natural or artificial material to material or a useful tool. Chemical Technology is a chemical produced for human consumption or engineering or manufacturing process chemical substances.
In the manufacture of this paper will discuss about a brief history of the development of chemical technology of ancient pre-historic, Egyptian times, the times of the Roman and Islamic times. This article will discuss some of the critical problems of modern chemical technology such as environmental pollution and the risk of death or injury and some solutions.
The early history of chemical technology initially very difficult to determine because human history has shown that age has little knowledge or knowledge of chemical technology that is the use of chemicals and chemical pronomic processing chemicals produced even much smaller pronomic than the modern chemical industry. Most of the chemicals produced in ancient times used for daily life such as food, clothing, and housing and community uses for the more sophisticated among others:
Salt in a medium is a chemical produced pronomic by a low technology that is drying sea water with the rays of the sinking sun or rock salt. Ancient human need to add salt lost through perspiration. And cooked pronomic foods generally do not contain enough salt. Therefore salt is supporting human needs must be met.
The process of fermentation is the chemical process that is known to all ancient peoples, among others, produce alcoholic liquor by fermentation of sugar. In the ancient Egypt, better known as the producer of fermented vinegar or acetic acid is used not only in food but also produce other substances.
For drawing and coloring to dye fabric is also important chemicals such as: painting on cave walls in Spain, Africa and Australia are using several colors like red, yellow and green to show that ancient man know about chemical colored clay, ore iron (red and yellow), copper and ferrous sulphate (green). Fabric dye produced from tumb
