Hayam Wuruk

Hayam Wuruk, also called (after 1350) Rajasanagara, Pa-ta-na-pa-na-wu, or Bhatara Prabhu, (1334–1389), was a Javanese King from the Rajasa Dynasty and the fourth monarch of the Majapahit Empire. Together with his prime minister Gajah Mada, he reigned the empire at the time of its greatest power. He was preceded by Tribhuwana Wijayatunggadewi and succeeded by his son-in-law Wikramawardhana. Most of the accounts of his life were taken from Nagarakretagama and Pararaton.

Early life

According to Nagarakretagama canto 1 stanza 4 and 5 (composed by Mpu Prapanca in 1365), Hayam Wuruk was born in 1256 Saka or correspond to 1334 CE, the same year that Mount Kelud erupted. Prapanca argued that this was the divine sign that Batara Gurunata (Javanese name for Shiva Mahadewa) has manifest Himself on earth, reincarnated as the Javanese king. Also in the same, Gajah Mada declared his oath Sumpah Palapa.

Hayam Wuruk's name can be translated as "scholar rooster". He was the son of Tribhuwana Tunggadewi and Sri Kertawardhana or Cakradhara. His mother was the daughter of Raden Wijaya founder of Majapahit, meanwhile his father was the son of Bhre Tumapel lesser king of Singhasari. Both Pararaton and Nagarakretagama praised Hayam Wuruk as a handsome, bright, talented, and exceptional student in the courtly martial arts of archery and fencing, also mastering politics and scriptures, as well as arts and music. He was known as an accomplished ceremonial dancer in the court. Some accounts tell of Hayam Wuruk's performances in a traditional ceremonial Javanese mask dance. His mother, Queen Tribhuwana, educated and groomed him to become the next monarch of Majapahit.

Jakarta

Jakarta /dʒəˈkɑːrtə/, officially known as the Special Capital Region of Jakarta (Indonesian: Daerah Khusus Ibu Kota Jakarta), is the capital and largest city of Indonesia, (though Jakarta is also a province) and one of the most populous urban agglomerations in the world.

Located on the northwest coast of Java, Jakarta is the country's economic, cultural and political centre, and with a population of 10,075,310 as of 2014. The official metropolitan area, known as Jabodetabek (a name formed by combining the initial syllables of Jakarta, Bogor, Depok, Tangerang and Bekasi), is the fourth largest in the world, yet the metropolis's suburbs still continue beyond it. Its unofficial built-up (metropolitan) area covers Bogor, Tangerang, Bekasi, Karawang, Serang, Purwakarta, Sukabumi and Subang regencies (123 districts) including also Tangerang, Bekasi, Tangerang Selatan, Depok, Serang and Cilegon Municipalities was home to 30,214,303 inhabitants as of 2010 census.

Established in the fourth century, the city became an important trading port for the Kingdom of Sunda. It was the de facto capital of the Dutch East Indies (known as Batavia at that time). Today, the city has continued as the capital of Indonesia since the country's independence was declared in 1945. The city is currently the seat of the ASEAN Secretariat as well as houses important financial institutions such as the Bank of Indonesia, the Indonesia Stock Exchange, and the corporate headquarters of numerous Indonesian companies and multinational corporations. Jakarta's business opportunities, as well as its potential to offer a higher standard of living, attract migrants from all over Indonesia, making the city a melting pot of many communities and cultures.

Ultra high frequency

Ultra high frequency (UHF) is the ITU designation for radio frequencies in the range between 300 MHz and 3 GHz, also known as the decimetre band as the wavelengths range from one meter to one decimetre. Radio waves with frequencies above the UHF band fall into the SHF (super-high frequency) or microwave frequency range. Lower frequency signals fall into the VHF (very high frequency) or lower bands. UHF radio waves propagate mainly by line of sight; they are blocked by hills and large buildings although the transmission through building walls is high enough for indoor reception. They are used for television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, and numerous other applications.

The IEEE defines the UHF radar band as frequencies between 300 MHz and 1 GHz. Two other IEEE radar bands overlap the ITU UHF band: the L band between 1 and 2 GHz and the S band between 2 and 4 GHz.
