Manfaat dan Efek Samping Bahan Kimia

Zat-zat yang ada dalam kehidupan kita sehari-hari kebanyakan tidak dalam keadaan murni, telah bercampur dengan dua atau lebih zat alinnya. Campuran suatu zat juga akan tetap mempertahankan sifat-sifat unsurnya. Oleh karena itu,suatu bahan kimia juga akan dipengaruhi oleh sifat,kegunaan,atau efek dari zat-zat yang menyusunnya. Kekuatan pengaruh sifat masing-masing zat juga bergantung pada kandungan dalam bahan yang bersangkutan. Banyak ragam bahan kimia yang ada dalam kehidupan sehari-hari.

Berikut ini sebagian manfaat dan efek samping bahan kimia :

1. Sabbun atau diterjen

Dalam kehidupan sehari-hari, kita juga telah mengenal berbagai bahan kimia pembersih, diantaranya sabun dan diterjen. Sabun dan ditergen dapat menjadikan lemak dan minyak yang tadinya tidak dapat bercampur dengan air menjadi mudah bercampur. Sabun dan ditergen dalam air juga dapat melepaskan sejenis ion yang telah memiliki bagian yang suka air (hidrofilik) sehingga dapat larut dalam air dan bagian yang tidak suka akan air (hidrofobik) sehingga larut dalam minyak atau lemak.

2. Pemutih pakaian

Pemutih biasanya telah dijual dalam bentuk larutannya dan digunakan untuk dapat menghilangkan kotoran atau noda berwarna yang sukar untuk dihilangkan dengan hanya mengguanakan sabun atau ditergen.

3. Pewangi pakaian

Pewangi juga merupakan bahan kimia lain yang erat kaitannya dengan kehidupan kita sehari-hari. Kita juga dapat memperoleh bahan pewangi dari bahan alam maupun sintetik. Bahan pewangi alami yang sudah kita kenal diantaranya telah diperoleh dari daun kayu putih, kulit kayu manis,batang kayu cendana,bunga kenanga,bunga melati dan buah pala. Bahan pewangi sintetik biasanya telah dipakai dalam berbagai pewangi atau parfum dalam kemasan.

4. Pestisida

Bahan kimia jenis pestisida erat sekali dengan kehidupan para petani. Pestisida dipakai untuk dapat memberantas hama tanaman sehingga tidak menganggu hasil produksi pertanian. Pestisida meliputi semua jenis obat (zat/bahan kimia) pembasmi hama yang ditujukan untuk dapat melindungi tanaman dari serangga,jamur,bakteri,virus, tikus,bekicot dan nematode (cacing).

saco-indonesia.com, Persebaya akhirnya telah mengantongi izin penggunaan Stadion Gelora Bung Tomo (GBT) sebagai homebase untuk kompetisi Indonesia Super League (ISL) 2014. Namun Persebaya telah diminta dalam melunasi biaya sewa selama semusim yang diperkirakan telah mencapai Rp 300 juta.

Kepastian itu telah tertuang dalam surat nomor 426.23/356/436.6.17/2014 yang telah ditandatangani langsung oleh Sekretaris Kota (Sekkota) Surabaya, Hendro Gunawan. Pemkot Surabaya pada prinsipnya telah memberikan lampu hijau bagi Persebaya untuk dapat menggunakan GBT.

"Alhamdulillah. Kami bersyukur akhirnya telah mendapat izin dari Pemkot Surabaya," ucap asisten manajer Persebaya, Amran Said Ali.

Untuk biaya sewa GBT, telah mengacu pada Peraturan Daerah Kota Surabaya Nomor 2 Tahun 2013 tentang Perubahan Atas Retribusi Pemakaian Kekayaan Daerah, maka setiap pertandingan dikenakan biaya sewa sebesar Rp 30 juta.

Amran juga telah menegaskan bahwa manajemen Persebaya siap melunasi biaya sewa stadion sepakbola terbesar di Jatim itu untuk semusim kompetisi penuh. "Kalau ada 10 pertandingan, maka total satu musim sewa GBT habis Rp 300 juta. Insya Allah, manajemen siap langsung melunasi," lanjut Amran.

Kepastian ini juga telah menjadi kabar gembira menjelang bergulirnya kompetisi ISL 2014. Sebab, dengan demikian manajemen Persebaya tak perlu pusing lagi memikirkan venue pertandingan. "Setelah ini manajemen juga siap melampirkan izin dari Polrestabes Surabaya sebagai pertimbangan," tutup Amran.

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.

WASHINGTON — During a training course on defending against knife attacks, a young Salt Lake City police officer asked a question: “How close can somebody get to me before I’m justified in using deadly force?”

Dennis Tueller, the instructor in that class more than three decades ago, decided to find out. In the fall of 1982, he performed a rudimentary series of tests and concluded that an armed attacker who bolted toward an officer could clear 21 feet in the time it took most officers to draw, aim and fire their weapon.

The next spring, Mr. Tueller published his findings in SWAT magazine and transformed police training in the United States. The “21-foot rule” became dogma. It has been taught in police academies around the country, accepted by courts and cited by officers to justify countless shootings, including recent episodes involving a homeless woodcarver in Seattle and a schizophrenic woman in San Francisco.

Now, amid the largest national debate over policing since the 1991 beating of Rodney King in Los Angeles, a small but vocal set of law enforcement officials are calling for a rethinking of the 21-foot rule and other axioms that have emphasized how to use force, not how to avoid it. Several big-city police departments are already re-examining when officers should chase people or draw their guns and when they should back away, wait or try to defuse the situation
