It was inspired by the pop art , one of them is Tapak Tilu, he became know and recognize the pattern of step of Kliningan or Bajidoran or Ketuk Tilu dance. Until he can develop a dance or art which is now in the know with the name Jaipongan . His first Jaipong creation has known by people are “ Daun Pulus Keser Bojong” and “Rendeng Bojong”, both of tahem are kind of women dance and couple dance.

The presence of Jaipongan dance has contributed greatly to the lovers dance more active to discover...

A lan MacDiarmid, co-discoverer of the field of conducting polymers, more commonly known as “synthetic metals,” was the chemist responsible in 1977 for the chemical and electrochemical doping of polyacetylene, (CH)x, the “prototype” conducting polymer, and the “rediscovery” of polyaniline, now the foremost industrial conducting polymer. Alan G. MacDiarmid shared a Nobel Prize in Chemistry with Dr. Alan J. Heeger and Dr. Hideki Shirakawa. The Royal Swedish Academy of Sciences awarded the prize to the three for the discovery and development of conductive polymers. Alan G. MacDiarmid (born April 14, 1927; mother, Ruby and father, Archibald MacDiarmid ) grew up in New Zealand, and received his Ph.D. at University of Wisconsin 1953 and at University of Cambridge, UK, 1955. He was associate professor at University of Pennsylvania 1956 and received a professorship there 1964. Since 1988 he is Blanchard Professor of Chemistry. In 1973, he began research on (SN)x, an unusual polymeric material ...

Abu’l-Abbas Ahmad ibn Muhammad ibn Kathir al-Farghani, born in Farghana, Transoxiana, was one of the most distinguished astronomers in the service of al-Mamun and his successors. He wrote "Elements of Astronomy " (Kitab fi al-Harakat al-Samawiya wa Jawami Ilm al-Nujum i.e. the book on celestial motion and thorough science of the stars), which was translated into Latin in the 12th century and exerted great influence upon European astronomy before Regiomontanus. He accepted Ptolemy’s theory and value of the precession, but thought that it affected not only the stars but also the planets. He determined the diameter of the earth to be 6,500 miles, and found the greatest distances and also the diameters of the planets. Al-Farghani’s activities extended to engineering. According to Ibn Tughri Birdi, he supervised the construction of the Great Nilometer at al-Fustat (old Cairo). It was completed in 861, the year in which the Caliph al-Mutawakkil, who ordered the construction, ...

G erman chemist, generally regarded as the founder of modern organic chemistry with his synthesis of acetic acid (ethanoic acid) – an organic compound – from inorganic starting materials. He was first to apply electrolysis to organic synthesis. Kolbe electrolysis of fatty (alkanoic) acids was the first known electrochemical synthesis. Kolbe was a German chemist. He was born near Gottingen and educated there. Kolbe studied for three years (1838-42) with Friedrich Wohler, and then served as an assistant of Robert Wilhelm Bunsen at the University of Marburg in 1842. After one year in Marburg, Kolbe obtained his PhD for work originally begun under Wohler’s direction. Kolbe remained as Bunsen’s assistant for a total of three years (1842-45). He spent 2 years (1845-46) at the London School of Mines, England, being an assistant to Lyon Playfair. From 1847 to 1851 Kolbe was engaged in editing the Handworterbuch der reinen und angewandten Chemie ( Dictionary of Pure and Applied Chemistry) w...

A bul Wafa Muhammad Ibn Muhammad Ibn Yahya Ibn Ismail al-Buzjani was born in Buzjan, Nishapur in 940 C.E. He flourished as a great mathematician and astronomer at Baghdad and died in 997/998 C.E. He learnt mathematics in Baghdad. In 959 C.E. he migrated to Iraq and lived there till his death. Abul Wafa’s main contribution lies in several branches of mathematics, especially geometry and trigonometry. In geometry his contribution comprises solution of geometrical problems with opening of the compass; construction of a square equivalent to other squares; regular polyhedra; construction of regular hectagon taking for its side half the side of the equilateral triangle inscribed in the same circle; constructions of parabola by points and geometrical solution of the equations: x4 = a and x4 + ax3 = b Abul Wafa’s contribution to the development of trigonometry was extensive. He was the first to show the generality of the sine theorem relative to spherical triangles. He developed a new method o...

A bul Hasan Ali Ibn Husain Ibn Ali Al-Masu’di was a descendant of Abdallah Ibn Masu’d, a companion of the Holy Prophet (peace be upon him). An expert geographer, a physicist and historian, Masu’di was born in the last decade of the 9th century C.E., his exact date of birth being unknown. He was a Mutazilite Arab, who explored distant lands and died at Cairo, in 957 C.E. He travelled to Fars in 915 C.E. and, after staying for one year in Istikhar, he proceeded via Baghdad to India, where he visited Multan and Mansoora before returning to Fars. From there he traveled to Kirman and then again to India. Mansoora in those days was a city of great renown and was the capital of the Muslim state of Sind. Around it, there were many settlements/townships of new converts to Islam. In 918 C.E., Masu’di traveled to Gujrat, where more than 10,000 Arab Muslims had settled in the sea-port of Chamoor. He also travelled to Deccan, Ceylon, Indo-China and China, and proceeded via Madagascar, Zanjibar an...

A bu Marwan Abd al-Malik Ibn Zuhr was born at Seville in 1091/c. 1094 C.E. After completing his education and specializing in medicine, he entered the service of Almoravides (Al-Murabatun), but after their defeat by the Al-Mohades (Al-Muwahadun), he served under ‘Abd al-Mu’min, the first Muwahid ruler. He died in Seville in 1161/c. 1162 C.E. As confirmed by George Sarton, he was not a Jew, but an orthodox Muslim. Ibn Zuhr was one of the greatest physicians and clinicians of the Muslim golden era and has rather been held by some historians of science as the greatest of them. Contrary to the general practice of the Muslim scholars of that era, he confined his work to only one field medicine. This enabled him to produce works of everlasting fame.

A bu Ali Hasan Ibn al-Haitham was one of the most eminent physicists, whose contributions to optics and the scientific methods are outstanding. Known in the West as Alhazen, Ibn al-Haitham was born in 965 C.E. in Basrah, and was educated in Basrah and Baghdad. Thereafter, he went to Egypt, where he was asked to find ways of controlling the flood of the Nile. Being unsuccessful in this, he feigned madness until the death of Caliph al-Hakim. He also travelled to Spain and, during this period, he had ample time for his scientific pursuits, which included optics, mathematics , physics, medicine and development of scientific methods on each of which he has left several outstanding books. He made a thorough examination of the passage of light through various media and discovered the laws of refraction. He also carried out the first experiments on the dispersion of light into its constituent colours. His book Kitab-al-Manadhir was translated into Latin in the Middle Ages, as also his book...

A bul Qasim Khalaf ibn al-Abbas al-Zahravi (known in the west as Abulcasis) was born in 936 C.E. in Zahra in the neighbourhood of Cordova . He became one of the most renowned surgeons of the era and was physician to King Al-Hakam-II of Spain. After a long medical career , rich with significant original contribution, he died in 1013 C.E. He is best known for his early and original breakthroughs in surgery as well as for his famous Medical Encyclopedia called Al-Tasrif, which is composed of thirty volumes covering different aspects of medical science. The more important part of this series comprises three books on surgery, which describe in detail of surgical treatment as based on the operations performed by him, including cauterization, removal of stone from the bladder , dissection of animals, midwifery, styptics, and surgery of eye, ear and throat . He perfected several delicate operations, including removal of the dead foetus and amputation. Al-Tasrif was first translated by Gherar...
