saco-indonesia.com, Gubernur DKI Jakarta Joko Widodo (Jokowi) telah menyebut, macet dan banjir dapat menyebabkan infrastruktur ibu kota terhambat. Namun, dia juga bersama Pemerintah Provinsi (Pemprov) DKI juga akan berupaya untuk dapat membangun Jakarta menuju kota internasional.

"Kita fokus ke situ, progresnya misalnya masuk ke industri-industri yang punya nilai tinggi. Ini juga akan kita pikirkan karena apa, infrastruktur kita terhambat karena macet dan banjir," ujar Jokowi di Balai Kota, Jakarta Pusat.

Menurut mantan wali kota Solo itu, apabila infrastruktur Jakarta akan dapat berjalan dengan baik, dia juga akan memikirkan untuk prestasi ibu kota yang sudah diciptakan. Sebab Jokowi juga menegaskan, dia akan fokus mengatasi macet dan banjir.

"Kalau infrastrukturnya sudah baik semuanya baru kita akan memikirkan prestasi-prestasi lainnya. Kalau belum apa yang harus kita lakukan. Artinya fasilitas kemacetan harus kita atasi, banjirnya bisa diminimalkan," kata Jokowi.

Lebih lanjut, Jokowi juga menambahkan, Pemprov DKI tahun ini telah memulai tahapan baru menuju Kota Jakarta berkelas internasional. "Saya kira kita sudah mulai kok dan ini kita kirim orang ke Taiwan untuk masuk ke manufaktur ke posisi ke atas," terang Jokowi.

Sebagai penerang, lampu listrik yang umum digunakan sebagai cahaya buatan untuk rumah tinggal, dapat dibedakan menjadi 3 golonga

Sebagai penerang, lampu listrik yang umum digunakan sebagai cahaya buatan untuk rumah tinggal, dapat dibedakan menjadi 3 golongan besar, yaitu lampu pijar, lampu halogen dan lampu berpendar. Banyaknya jenis lampu yang beredar saat ini telah membuat Anda perlu memperhatikan faktor apa saja yang perlu dipertimbangkan saat memilih lampu. Berikut ini ada beberapa faktor yang dapat Anda pertimbangkan:

1. Langkah pertama yang bisa Anda lakukan adalah menentukan titik-titik penempatan lampu, terutama yang ditanam di dinding atau plafon. Hal ini dilakukan sebelum anda membangun atau merenovasi rumah tinggal.

2. Ada baiknya jika penempatan lampu disesuaikan dengan kondisi lingkungan. Maksudnya, untuk lampu yang diletakkan di luar sebaiknya menggunakan bahan stainless steel, aluminium atau besi yang sudah dicat antikarat.

3. Menentukan warna cahaya lampu yang ingin digunakan. Lampu dengan karakter cahaya kekuningan disinyalir mampu membangkitkan suasana yang hangat dan romantis, sehingga sangat cocok ditempatkan di ruang tidur atau ruangan lain yang digunakan untuk bersantai. Sementara cahaya putih lebih cocok digunakan di tempat kerja. Penentuan warna cahaya lampu ini dengan sendirinya akan membimbing Anda untuk menentukan pilihan antara lampu neon dan lampu pijar.

4. Sesuaikan model lampu dengan karakter rumah. Lampu dengan desain tradisional klasik tentu akan terlihat jomplang bila ditempatkan pada rumah yang memiliki konsep modern minimalis.

5. Sifat lampu yang memancarkan panas juga dapat dijadikan faktor penimbang saat anda memilih rumah lampu. Sebagai suatu kesatuan, rumah lampu yang anda pilih sebaiknya tahan terhadap panas, tidak mudah leleh dan tidak mudah terbakar.

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.


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.


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


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.

Mr. Alger, who served five terms from Texas, led Republican women in a confrontation with Lyndon B. Johnson that may have cost Richard M. Nixon the 1960 presidential election.
