saco-indonesia.com, Grup band Slank telah menilai para koruptor telah menghancurkan bangsa Indonesia. Mereka juga telah memiliki cara tersendiri untuk dapat menghadapi para koruptor.

"Balik ke ideologi, kita tidak punya ideologi dan idealisme itu yang buat rakus," kata Bimbim, drumer Slank, di Taman Ismail Marzuki, Jakarta.

Bimbim juga mengatakan, sejelek-jeleknya band Slank masih memiliki ideologi yaitu Slank. Lebih lanjut, Bimbim juga mengatakan hukuman yang paling baik untuk para koruptor ialah tembak mati.

"Slank sih ngadepin koruptor hukum tembak biar kapok," tandas Bimbim.

Bimbim juga menyebut, politikus yang telah korupsi pantas disebut politikus alay. "Manusia-manusia yang tidak punya ideologi sama sekali, mereka alay politik sisi alay yang ingin mencoba bermain di demokrasi, boleh bilang Indonesia demokrasi alay," kata Bimbim dengan tertawa

Slank juga berharap ke depannya masyarakat dapat berpikir positif. Sebab, negara yang maju ialah negara yang telah memiliki anak muda dengan penuh kreasi.

"Harus berpikir positif thinking selalu positif bawa Indonesia maju," tandas Bimbim.

Cara Memilih Material Pipa

"PIPA SEAMLESS" Material pipa ada berbagai jenis. Bagaimana cara untuk menentukan material yang harus digunakan? Untuk dapat menentukan material, terutama untuk bidang industri, faktor yang paling penting adalah fluida apa yang akan mengalir didalamnya. Selain itu, kondisi luar dari pipa juga akan mempengaruhi. Dan terakhir, tentu saja dalam sisi ekonomi juga akan menjadi dasar pemilihan material.
Pipa juga dapat dibagi menjadi 2 bagian besar. Pipa dari logam dan non-logam. Logam telah terdiri dari carbon steel, stainless steel, aluminium, nickel dan lainnya. Berikut ini adalah contoh dalam desain pipa untuk pabrik industri gas alam, minyak, atau pabrik kimia lainnya.
Pertama, insinyur proses harus bisa menghitung apa dan berapa banyak macam kandungan yang akan melewati pipa. Pada dasarnya, semua pipa untuk proses biasanya harus memakai pipa logam dan dimulai dari material carbon steel yang paling murah.
Akibat aliran fluida, bagian dalam pipa akan mengalami korosi, dan salah satu cara untuk dapat menetapkan kecepatan korosi adalah memakai grafik de Waard – Milliams nomograph. Grafik ini membantu untuk dapat menentukan berapa kecepatan korosi (mm/tahun) yang telah disebabkan adanya kandungan CO2 dalam fluida.
Problem disebabkan korosi juga dapat diatasi dengan menambah ketebalan pipa sebesar kecepatan korosi dikali tahun lamanya pabrik didesain. Tetapi, jika total ketebalan yang dibutuhkan untuk dapat mengatasi korosi itu terlalu tebal, pipa akan menjadi sangat tebal dan tidak efektif dalam pembangunannya. Untuk keadaan ini, pipa dari stainless steel telah menjadi pilihan selanjutnya.
Selain korosi, suhu fluida juga dapat menentukan material pipa. Semakin rendah suhu, logam akan menjadi mudah mengalami retakan. Ini karena sifat brittle (getas)  logam bertambah pada suhu rendah . Stainless steel merupakan salah satu yang tahan akan suhu rendah. Karena itu, untuk cryogenic service (fluida dengan suhu operasi dibawah -196 degC) stainless steel adalah material yang cocok dibandingkan dengan carbon steel.
Stainless steel sering disebut juga corrosion resistance alloy (campuran logam tahan korosi) dan tentunya akan lebih mahal jika dibandingkan carbon steel. Stainless steel bisa dibagi menjadi beberapa jenis, contohnya austenitic, feritic, martenistic, duplex dan high alloy stainless steel (campuran tinggi logam stainless steel). Sayangnya, stainless steel tidak tahan terhadap semua jenis korosi, terutama korosi yang disebabkan oleh klorida, sulfida serta fluida asam (sour fluid) lainnya.
Untuk sistem pipa yang mengalirkan fluida asam (piping system for sour service) biasanya di desain berdasarkan standar NACE (National Association of Corrosion Engineers) MR0175. Mulai tahun 2003, standar NACE MR0175 bersatu dengan ISO 15156 dan yang telah memiliki syarat desain yang sulit dibandingkan edisi tahun sebelumnya.

Berdasarkan NACE MR0175/ISO 15156, penggunaan austenitic stainless steel telah dibatasi oleh kombinasi dari kadar khlorida, H2S (hydrogen sulfide) dan suhu fluida. Jika austenitic stainless steel tidak dapat digunakan, maka penggunaan duplex atau high alloy stainless steel merupakan pilihan selanjutnya. Jika duplex atau high alloy stainless steel juga tidak dapat digunakan, maka pilihan selanjutnya adalah menggunakan logam campuran nikel seperti incoloy dan inconel.
Semakin tahan terhadap berbagai korosi, semakin mahal harga material tersebut. Untuk dapat mengurangi biaya, pengaplikasian cladding atau overlay juga merupakan salah satu alternatif. Misalnya dengan menggunakan pipa dari carbon steel dengan dilapisi logam mahal pada bagian dalamnya saja yang bersentuhan langsung dengan fluida sumber korosi akan bisa menekan biaya tanpa mengurangi ketahanan terhadap korosi.
Pemilihan material ini bukan hanya untuk pipa, tetapi juga berlaku untuk bejana (vessel), katup (valve) dan elemen pipa lainnya. Untuk katup, walaupun material dari badan katup bisa memakai carbon steel, tetapi bagian dimana korosi tidak diperbolehkan untuk dapat menjaga kemampuan katup untuk menyekat (sering disebut sebagai trim, seperti bagian valve seat, stem dan lainnya), maka penggunaan stainless steel atau logam tahan korosi lainnya menjadi keharusan.
Pada saat melakukan pemilihan material yang sebenarnya, mungkin tidak akan semudah yang dijabarkan diatas, tetapi secara umum, begitulah proses pemilihan material pada saat mendesain pabrik industri.

Even as a high school student, Dave Goldberg was urging female classmates to speak up. As a young dot-com executive, he had one girlfriend after another, but fell hard for a driven friend named Sheryl Sandberg, pining after her for years. After they wed, Mr. Goldberg pushed her to negotiate hard for high compensation and arranged his schedule so that he could be home with their children when she was traveling for work.

Mr. Goldberg, who died unexpectedly on Friday, was a genial, 47-year-old Silicon Valley entrepreneur who built his latest company, SurveyMonkey, from a modest enterprise to one recently valued by investors at $2 billion. But he was also perhaps the signature male feminist of his era: the first major chief executive in memory to spur his wife to become as successful in business as he was, and an essential figure in “Lean In,” Ms. Sandberg’s blockbuster guide to female achievement.

Over the weekend, even strangers were shocked at his death, both because of his relatively young age and because they knew of him as the living, breathing, car-pooling center of a new philosophy of two-career marriage.

“They were very much the role models for what this next generation wants to grapple with,” said Debora L. Spar, the president of Barnard College. In a 2011 commencement speech there, Ms. Sandberg told the graduates that whom they married would be their most important career decision.

In the play “The Heidi Chronicles,” revived on Broadway this spring, a male character who is the founder of a media company says that “I don’t want to come home to an A-plus,” explaining that his ambitions require him to marry an unthreatening helpmeet. Mr. Goldberg grew up to hold the opposite view, starting with his upbringing in progressive Minneapolis circles where “there was woman power in every aspect of our lives,” Jeffrey Dachis, a childhood friend, said in an interview.

The Goldberg parents read “The Feminine Mystique” together — in fact, Mr. Goldberg’s father introduced it to his wife, according to Ms. Sandberg’s book. In 1976, Paula Goldberg helped found a nonprofit to aid children with disabilities. Her husband, Mel, a law professor who taught at night, made the family breakfast at home.

Later, when Dave Goldberg was in high school and his prom date, Jill Chessen, stayed silent in a politics class, he chastised her afterward. He said, “You need to speak up,” Ms. Chessen recalled in an interview. “They need to hear your voice.”

Years later, when Karin Gilford, an early employee at Launch Media, Mr. Goldberg’s digital music company, became a mother, he knew exactly what to do. He kept giving her challenging assignments, she recalled, but also let her work from home one day a week. After Yahoo acquired Launch, Mr. Goldberg became known for distributing roses to all the women in the office on Valentine’s Day.

Ms. Sandberg, who often describes herself as bossy-in-a-good-way, enchanted him when they became friendly in the mid-1990s. He “was smitten with her,” Ms. Chessen remembered. Ms. Sandberg was dating someone else, but Mr. Goldberg still hung around, even helping her and her then-boyfriend move, recalled Bob Roback, a friend and co-founder of Launch. When they finally married in 2004, friends remember thinking how similar the two were, and that the qualities that might have made Ms. Sandberg intimidating to some men drew Mr. Goldberg to her even more.

Over the next decade, Mr. Goldberg and Ms. Sandberg pioneered new ways of capturing information online, had a son and then a daughter, became immensely wealthy, and hashed out their who-does-what-in-this-marriage issues. Mr. Goldberg’s commute from the Bay Area to Los Angeles became a strain, so he relocated, later joking that he “lost the coin flip” of where they would live. He paid the bills, she planned the birthday parties, and both often left their offices at 5:30 so they could eat dinner with their children before resuming work afterward.

Friends in Silicon Valley say they were careful to conduct their careers separately, politely refusing when outsiders would ask one about the other’s work: Ms. Sandberg’s role building Facebook into an information and advertising powerhouse, and Mr. Goldberg at SurveyMonkey, which made polling faster and cheaper. But privately, their work was intertwined. He often began statements to his team with the phrase “Well, Sheryl said” sharing her business advice. He counseled her, too, starting with her salary negotiations with Mark Zuckerberg.

“I wanted Mark to really feel he stretched to get Sheryl, because she was worth it,” Mr. Goldberg explained in a 2013 “60 Minutes” interview, his Minnesota accent and his smile intact as he offered a rare peek of the intersection of marriage and money at the top of corporate life.

 

 

While his wife grew increasingly outspoken about women’s advancement, Mr. Goldberg quietly advised the men in the office on family and partnership matters, an associate said. Six out of 16 members of SurveyMonkey’s management team are female, an almost unheard-of ratio among Silicon Valley “unicorns,” or companies valued at over $1 billion.

When Mellody Hobson, a friend and finance executive, wrote a chapter of “Lean In” about women of color for the college edition of the book, Mr. Goldberg gave her feedback on the draft, a clue to his deep involvement. He joked with Ms. Hobson that she was too long-winded, like Ms. Sandberg, but aside from that, he said he loved the chapter, she said in an interview.

By then, Mr. Goldberg was a figure of fascination who inspired a “where can I get one of those?” reaction among many of the women who had read the best seller “Lean In.” Some lamented that Ms. Sandberg’s advice hinged too much on marrying a Dave Goldberg, who was humble enough to plan around his wife, attentive enough to worry about which shoes his young daughter would wear, and rich enough to help pay for the help that made the family’s balancing act manageable.

Now that he is gone, and Ms. Sandberg goes from being half of a celebrated partnership to perhaps the business world’s most prominent single mother, the pages of “Lean In” carry a new sting of loss.

“We are never at 50-50 at any given moment — perfect equality is hard to define or sustain — but we allow the pendulum to swing back and forth between us,” she wrote in 2013, adding that they were looking forward to raising teenagers together.

“Fortunately, I have Dave to figure it out with me,” she wrote.

The 2015 Met Gala has only officially begun, but there's a clear leader in the race for best couple, no small feat at an event that threatens to sap Hollywood of every celebrity it has for the duration of an East Coast evening.

That would be Marc Jacobs and his surprise guest (who, by some miracle, remained under wraps until their red carpet debut), Cher.

“This has been a dream of mine for a very, very long time,” Mr. Jacobs said.

It is Cher's first appearance at the Met Gala since 1997, when she arrived on the arm of Donatella Versace.
