Tokoh Dunia

Banyak sekali tokoh yang menggemparkan dunia dan menorehkan sejarah yang membuat pekerjaan manuasia jadi lebih mudah seperti saat ini, kami disini menyediakan dan akan melengkapi isi konten ini untuk pembelajaran dan juga agar kita dapat mengenal lebih dekat dengan sang tokoh yang saat ini mungkin kita rasakan hasil karyanya dimasa lampau silam, berikut salah satu tokoh yang dapat kami paparkan :

Khoirul Anwar - Pemilik Paten Teknologi 4G berbasis OFDM


Professor Khoirul Anwar lahir pada 22 Agustus 1978 di Kediri, Jawa Timur. ia merupakan Putra dari pasangan (almarhum) Sudjianto dengan Siti Patmi seorang petani di kediri. Ayahnya meninggal karena sakit saat ia baru lulus SD tahun 1990.

Ayah Khoirul meninggal karena sakit, saat ia baru lulus SD pada 1990. Ibunyalah kemudian berusaha keras menyekolahkannya, walaupun kedua orang tuanya tidak ada yang lulus SD. Sejak kecil, Khoirul hidup dalam kemiskinan.

Tapi ada saja jalan baginya untuk terus menuntut ilmu. Misalkan, ketika melanjutkan SMA di Kediri, tiba-tiba ada orang yang menawarkan kos gratis untuknya. Kemudian ia meneruskan kuliah di ITB Bandung Jurusan Teknik Elektro lulus dengan predikat cum laude di tahun 2000.

Selama 4 tahun ia selalu mendapatkan beasiswa. “Orang tua saya tidak perlu mengirimkan uang lagi,” kata Khoirul mengenang masa lalunya. Otaknya yang encer terus membawa Khoirul ke pendidikan yang tinggi.

Setelah itu ia mendapatkan beasiswa untuk melanjutkan S2 dari Panasonic di Nara Institute of Science and Technology (NAIST) Jepang dan lulus pada tahun 2005, dan selanjutnya kemudian ia mendapatkan beasiswa untuk melanjutkan kuliah S3 dari perusahaan Jepang dikampus yang sama Nara Institute of Science and Technology (NAIST) Jepang.

Khoirul Anwar kemudian menikah dengan Sri Yayu Indriyani dan dikaruniai tiga orang putra, Khoirul tinggal di Nomi, Ishikawa, tak jauh dari tempat kerjanya. Meski berprestasi cemerlang di Jepang, namun Khoirul menyimpan keinginan untuk kembali ke Indonesia suatu hari nanti.

Mengenai penemuannya adalah sebuah cara mengurangi daya transmisi pada sistem multicarrier seperti Orthogonal frequency-division multiplexing (OFDM) dan Multi-carrier code division multiple access (MC-CDMA). Caranya yaitu dengan memperkenalkan spreading code menggunakan Fast Fourier Transform sehingga kompleksitasnya menjadi sangat rendah. Dengan metode ini ia bisa mengurangi fluktuasi daya.

Dia mengurangi daya transmisi pada orthogonal frequency division multiplexing. Hasilnya, kecepatan data yang dikirim bukan menurun seperti lazimnya, melainkan malah meningkat. “Kami mampu menurunkan power sampai 5dB=100 ribu kali lebih kecil dari yang diperlukan sebelumnya,” kata dia. Dunia memujinya. Khoirul juga mendapat penghargaan bidang Kontribusi Keilmuan Luar Negeri oleh Konsulat Jenderal RI Osaka pada 2007.

Maka peralatan telekomunikasi yang digunakan tidak perlu menyediakan cadangan untuk daya yang tinggi. Belakangan, temuan ini ia patenkan. Teknik ini telah dipakai oleh perusahaan satelit Jepang. Dan yang juga membuatnya membuatnya kaget, sistem 4G ternyata sangat mirip dengan temuan yang ia patenkan itu.

Kemudian penemuan lainnya adalah dosen sekaligus peneliti asal Indonesia yang bekerja di laboratoriom Information Theory and Signal Processing, Japan Advanced Institute of Science and Technology, di Jepang Saat itu terdesak karena harus mengajukan tema penelitian untuk mendapatkan dana riset, Khoirul memeras otaknya. Akhirnya ide itu muncul juga dari Drag*n B*ll Z, film animasi Jepang yang kerap ia tonton.

Ketika Goku, tokoh utama Drag*n B*ll Z, hendak melayangkan jurus terdahsyatnya, ‘Genki Dama’ alias Spirit Ball, Goku akan menyerap semua energi mahluk hidup di alam, sehingga menghasilkan tenaga yang luar biasa.

Khoirul Anwar - Patent Owner OFDM-based 4G Technology


   Khoirul Professor Anwar was born on August 22, 1978 in Kediri, East Java. he is the son of the couple (deceased) Sudjianto with Siti PATMI a farmer in Kediri. His father died of illness when he had finished primary school in 1990.

Khoirul father died of illness, when she graduated from elementary school in 1990, her mother, and then try hard to send him, although both parents no elementary school. Since childhood, Khoirul live in poverty.

But there was just a way for him to continue studying. For example, when continued high school in Kediri, suddenly there are people offering free boarding for him. Then he went to college at the Bandung Institute of Technology Department of Electrical Engineering graduated cum laude in 2000.

For 4 years, she had received a scholarship. "My parents do not need to send any more money," said Khoirul memory of his past. Aqueous brain continues to bring Khoirul to higher education.

After that he got a scholarship to continue S2 from Panasonic at the Nara Institute of Science and Technology (NAIST) Japan and graduated in 2005, and then later he won a scholarship to continue studying S3 from the Japanese company campus same Nara Institute of Science and Technology ( NAIST) Japan.

Khoirul Anwar later married with Sri Yayu Indriyani and blessed with three sons, Khoirul stayed in Nomi, Ishikawa, not far from his workplace. Despite a brilliant achievement in Japan, but Khoirul save the desire to return to Indonesia one day.

Regarding inventions was a way of reducing transmission power in multicarrier systems such as Orthogonal frequency-division multiplexing (OFDM) and Multi-carrier code division multiple access (MC-CDMA). The trick is to introduce the spreading code using Fast Fourier Transform so it becomes very low complexity. With this method it can reduce power fluctuations.

He reduces the transmitting power on orthogonal frequency division multiplexing. As a result, the speed of data sent is not declining as usual, but actually increased. "We were able to reduce power to 5dB = 100 thousand times smaller than previously required," he said. World praised. Khoirul also received an award in the Scientific Contributions of Foreign Affairs by the Consulate General Osaka in 2007.

Then the telecom equipment used do not need to provide backup for power is high. Later, these findings he patented. This technique has been used by the Japanese satellite company. And that also makes it shocked him, the 4G system was very similar to the findings that he patented it.

Then the other invention is a lecturer and researcher from Indonesia who work in laboratoriom Information Theory and Signal Processing, Japan Advanced Institute of Science and Technology, in Japan are currently being pressured because it must propose research themes to obtain research funds, Khoirul racking his brains. Finally, the idea came also from Drag * n B * ll Z, Japanese animated film which she often watched.

As Goku, the main character Drag * n B * ll Z, about to cast a terdahsyatnya stance, 'Genki Dama' aka Spirit Ball, Goku will absorb all the energy living creatures in nature, resulting in tremendous power.
