Hari ini, 25 tahun lalu, internet pertama kali telah diperkenalkan pada dunia. Sejak hari itu pula dunia berubah.

Hari ini, 25 tahun lalu, internet pertama kali telah diperkenalkan pada dunia. Sejak hari itu pula dunia berubah.

tepat pada 12 Maret 2014 ini, internet atau world wide web genap berusia setengah abad. Tak terasa, pada hari inilah pertama kalinya Sir Tim Berners-Lee telah memperkenalkan dunia maya pada khalayak lewat sebuah ceramah ilmiah.

Secara perlahan, internet pun juga mulai mengubah cara hidup manusia. Di 1995, hanya ada sekitar 14 persen saja orang Amerika yang memilikinya, namun kini siapa saja bisa mengaksesnya dengan mudah bahkan lewat ponsel murah.

Saat ini, hampir seluruh kegiatan kita dilakukan lewat layanan revolusioner ini. Mulai dari belajar, bekerja, bahkan bersosialisasi pun juga bisa dilakukan hanya dengan mengetik www di peramban internet.

Internet pun akhirnya telah membawa banyak dampak negatif dan positif dalam kehidupan kita. Ada yang terbantu dengan keberadaannya, namun tak sedikit yang jadi sial karenanya.

Apapun itu, dunia telah berubah akibat internet. Selamat ulang tahun internet

PT Perkebunan Nusantara IX selama beberapa tahun terakhir terus mengembangkan dan mengelola sejumlah perkebunan di wilayah Provinsi Jawa Tengah sebagai salah satu destinasi pariwisata dalam bentuk wisata agro.

BREBES, Saco-Indonesia - PT Perkebunan Nusantara IX selama beberapa tahun terakhir terus mengembangkan dan mengelola sejumlah perkebunan di wilayah Provinsi Jawa Tengah sebagai salah satu destinasi pariwisata dalam bentuk wisata agro. Selain Kampoeng Kopi Banaran di Bawen dan Ambarawa, saat ini pengembangan wisata agro Kebun Kaligua di Brebes dan Kebun Semugih di Pemalang juga terus ditingkatkan.

Direktur Utama PTPN IX Adi Prasongko mengatakan, pengembangan wisata agro dilakukan karena sejak 2005 bisnis wisata agro sangat menguntungkan PTPN. ”Karena menguntungkan, kami sudah tidak ragu lagi. Bahkan, ke depan wisata agro tak lagi diolah administratur, tetapi akan dikelola profesional dengan struktur sendiri,” ujarnya, Sabtu (1/6/2013), di Kebun Kaligua, Brebes. Jajaran direksi PTPN IX beserta Bupati Brebes menghadiri rangkaian acara Hari Ulang Tahun Ke-42 Pengolahan Teh Hitam di Kebun Kaligua.

Wisata agro Kebun Kaligua dan Kebun Semugih berada di kawasan perkebunan teh yang telah ada sejak zaman Belanda. Kebun Kaligua merupakan perkebunan teh di barat Gunung Slamet di Desa Pandansari, Kecamatan Paguyangan, Brebes. Kebun Semugih, perkebunan teh yang berada di lereng utara Gunung Slamet, berlokasi di Desa Banyumudal, Kecamatan Moga, Pemalang.

Sebagai bentuk keseriusan PTPN IX dalam mengembangkan wisata agro, di kedua kebun itu sedang dibangun mikrohidro atau pembangkit listrik dengan menggunakan tenaga air. Selain itu, dilakukan juga pembenahan dan pembangunan sarana penginapan yang lebih nyaman bagi wisatawan serta penambahan wahana permainan untuk menarik perhatian wisatawan, terutama anak-anak.

”Untuk informasi ke luar, kami akan membenahi website sehingga wisatawan yang ingin menikmati wisata alam mendapat informasi. Kami juga ingin menarik minat para fotografer, termasuk fotografer dunia, bahwa di sini ada obyek menarik yang layak difoto,” ujar Adi.

PTPN IX juga akan mengarahkan wisata agro pada generasi muda, terutama anak-anak, dalam bentuk edukasi. Ada rencana memadukan pariwisata panorama dengan industri yang ada, seperti pabrik teh. ”Jadi, pengelolaan teh bisa diketahui masyarakat umum,” ungkapnya.

Bupati Brebes Idza Priyanti mengungkapkan, Pemerintah Kabupaten Brebes mendukung upaya PTPN IX menjadikan Kebun Kaligua sebagai tempat wisata agro. Untuk saat ini, Pemkab akan membantu pemeliharaan jalan-jalan di desa yang menuju Kebun Kaligua.

”Sementara ini pemeliharaan dulu karena masih pembangunan mikrohidro. Harapan saya, APBD 2014 bisa alokasikan untuk membangun jalan di sini. Yang jelas, kami akan memperhatikan hal ini karena mendukung pariwisata,” paparnya.

Kebun Kaligua menawarkan panorama alam berupa hamparan kebun teh seluas 509 hektar. Di kebun ini, para wisatawan dapat mengunjungi pabrik pengolahan teh hitam. Kebun Semugih menawarkan pemandangan, pemetikan, budidaya, dan pengolahan teh. (son)

Though Robin and Joan Rolfs owned two rare talking dolls manufactured by Thomas Edison’s phonograph company in 1890, they did not dare play the wax cylinder records tucked inside each one.

The Rolfses, longtime collectors of Edison phonographs, knew that if they turned the cranks on the dolls’ backs, the steel phonograph needle might damage or destroy the grooves of the hollow, ring-shaped cylinder. And so for years, the dolls sat side by side inside a display cabinet, bearers of a message from the dawn of sound recording that nobody could hear.

In 1890, Edison’s dolls were a flop; production lasted only six weeks. Children found them difficult to operate and more scary than cuddly. The recordings inside, which featured snippets of nursery rhymes, wore out quickly.

Yet sound historians say the cylinders were the first entertainment records ever made, and the young girls hired to recite the rhymes were the world’s first recording artists.

Year after year, the Rolfses asked experts if there might be a safe way to play the recordings. Then a government laboratory developed a method to play fragile records without touching them.

Audio

The technique relies on a microscope to create images of the grooves in exquisite detail. A computer approximates — with great accuracy — the sounds that would have been created by a needle moving through those grooves.

In 2014, the technology was made available for the first time outside the laboratory.

“The fear all along is that we don’t want to damage these records. We don’t want to put a stylus on them,” said Jerry Fabris, the curator of the Thomas Edison Historical Park in West Orange, N.J. “Now we have the technology to play them safely.”

Last month, the Historical Park posted online three never-before-heard Edison doll recordings, including the two from the Rolfses’ collection. “There are probably more out there, and we’re hoping people will now get them digitized,” Mr. Fabris said.

The technology, which is known as Irene (Image, Reconstruct, Erase Noise, Etc.), was developed by the particle physicist Carl Haber and the engineer Earl Cornell at Lawrence Berkeley. Irene extracts sound from cylinder and disk records. It can also reconstruct audio from recordings so badly damaged they were deemed unplayable.

“We are now hearing sounds from history that I did not expect to hear in my lifetime,” Mr. Fabris said.

The Rolfses said they were not sure what to expect in August when they carefully packed their two Edison doll cylinders, still attached to their motors, and drove from their home in Hortonville, Wis., to the National Document Conservation Center in Andover, Mass. The center had recently acquired Irene technology.

Audio

Cylinders carry sound in a spiral groove cut by a phonograph recording needle that vibrates up and down, creating a surface made of tiny hills and valleys. In the Irene set-up, a microscope perched above the shaft takes thousands of high-resolution images of small sections of the grooves.

Stitched together, the images provide a topographic map of the cylinder’s surface, charting changes in depth as small as one five-hundredth the thickness of a human hair. Pitch, volume and timbre are all encoded in the hills and valleys and the speed at which the record is played.

At the conservation center, the preservation specialist Mason Vander Lugt attached one of the cylinders to the end of a rotating shaft. Huddled around a computer screen, the Rolfses first saw the wiggly waveform generated by Irene. Then came the digital audio. The words were at first indistinct, but as Mr. Lugt filtered out more of the noise, the rhyme became clearer.

“That was the Eureka moment,” Mr. Rolfs said.

In 1890, a girl in Edison’s laboratory had recited:

There was a little girl,

And she had a little curl

Audio

Right in the middle of her forehead.

When she was good,

She was very, very good.

But when she was bad, she was horrid.

Recently, the conservation center turned up another surprise.

In 2010, the Woody Guthrie Foundation received 18 oversize phonograph disks from an anonymous donor. No one knew if any of the dirt-stained recordings featured Guthrie, but Tiffany Colannino, then the foundation’s archivist, had stored them unplayed until she heard about Irene.

Last fall, the center extracted audio from one of the records, labeled “Jam Session 9” and emailed the digital file to Ms. Colannino.

“I was just sitting in my dining room, and the next thing I know, I’m hearing Woody,” she said. In between solo performances of “Ladies Auxiliary,” “Jesus Christ,” and “Dead or Alive,” Guthrie tells jokes, offers some back story, and makes the audience laugh. “It is quintessential Guthrie,” Ms. Colannino said.

The Rolfses’ dolls are back in the display cabinet in Wisconsin. But with audio stored on several computers, they now have a permanent voice.
