Mantan Wakil Presiden Jusuf Kalla menyatakan mendukung rencana Pemerintah untuk memangkas subsidi bahan bakar minyak (BBM).

JAKARTA, Saco-Indonesia.com — Mantan Wakil Presiden Jusuf Kalla menyatakan mendukung rencana Pemerintah untuk memangkas subsidi bahan bakar minyak (BBM). Menurut dia langkah tersebut perlu dilakukan untuk menyelamatkan perekonomian bangsa.

JK menjelaskan, kebijakan tersebut akan sangat berkaitan dengan kepentingan ekonomi bangsa. Menurut dia, pemangkasan subsidi BBM dapat memberi pengaruh untuk pembangunan nasional ke depannya.

"Ya, selayaknya. Tentu karena ini untuk kepentingan ekonomi bangsa," kata Kalla, seusai menghadiri peringatan Hari Lahir Pancasila di Tugu Proklamasi, Jakarta, Sabtu (1/6/2013).

Kalla beranggapan, beban masyarakat justru akan bertambah berat bila subsidi BBM tetap digelontorkan. Pasalnya, subsidi tersebut dianggapnya akan menimbulkan beban hutang luar negeri. "Itu subsidi itu kan dibayar dengan hutang, jangan lupa," katanya.

Seperti diberitakan, pemerintah berencana memangkas subsidi BBM. Dengan begitu, harga premium akan mengalami kenaikan menjadi Rp 6.500 per liter dan solar Rp 5.500 per liter.

Jika direalisasikan, sebanyak 15,53 juta keluarga miskin akan menerima uang tunai Rp 150.000 per bulan selama lima bulan dan kompensasi dalam bentuk program lainnya.

Jenis-jenis Valve dan Fungsinya

Jenis-jenis valve dan fungsinya :
 
1. Gate Valve
Gate Valve adalah valve yang paling sering dipakai pada sistem perpipaan. Fungsinya untuk dapat membuka dan menutup aliran (on-off), tetapi tidak bisa untuk mengatur besar kecil aliran (throttling). Kelebihan Gate Valve, minimnya halangan/ resistan saat valve ini telah dibuka penuh, sehingga aliran bisa
maksimal. Gate Valve telah mengontrol aliran melalui badan valve yang berbentuk pipa, dengan sebuah lempengan atau baji vertikal  yang bisa bergeser naik turun saat handel valve diputar. Valve ini telah didesain untuk dapat mengatur posisi terbuka penuh, atau tertutup penuh. Jika valve ini dalam keadaan setengah terbuka, maka akan dapat menyebabkan pengikisan pada badan valve, dan turbulensi aliran zat bisa dapat menyebabkan getaran pada baji valve sehingga dapat menghasilkan suara gemeretak.

2. Globe Valve
Globe Valve biasanya akan digunakan pada situasi dimana pengaturan besar kecil aliran (throttling) sangat diperlukan. Dengan mudah memutar handel valve, besarnya aliran zat yang telah melewati valve bisa diatur. Dudukan valve yang sejajar dengan aliran, telah membuat globe valve efisien ketika dapat mengatur besar kecilnya aliran dengan minimum erosi piringan dan dudukan. Namun demikian tahanan didalam valve cukup besar. Desain globe valve yang sedemikian rupa, telah memaksa adanya perubahan arah aliran zat didalam valve, sehingga tekanan menurun drastis dan dapat menyebabkan turbulensi di dalam valve itu sendiri. Dengan demikian, Globe Valve tidak disarankan diinstal pada sistem yang menghindari penurunan tekanan, dan sistem yang menghindari tahanan pada aliran.

3. Angle Valve  
Sama seperti globe valve, angle valve juga akan digunakan pada situasi dimana pengaturan besar kecil aliran telah diperlukan (throttling). Namun angle valve telah di buat dengan sudut 90°, hal ini untuk dapat mengurangi pemakaian elbow 90° dan fitting tambahan.
 
4. Check Valve
Check Valve telah memiliki perbedaan yang sangat signifikan dari Gate Valve dan Globe Valve. Valve ini telah di disain untuk dapat mencegah aliran balik. Ada beberapa jenis check valve, tapi ada 2 jenis yang paling umum yaitu Swing Check dan Lift Check. Swing Check Valve biasanya telah dipasangkan dengan Gate Valve, sedangkan Lift Check Valve oleh beberapa pabrikan digunakan untuk dapat menggantikan fungsi Ball Valve sebagai Ball Check Valve. Check Valve tidak menggunakan handel untuk dapat mengatur aliran, tapi dengan menggunakan gravitasi dan tekanan dari aliran fluida itu sendiri. Karena fungsinya yang juga dapat mencegah aliran balik (backflow). Check Valve juga sering digunakan sebagai pengaman dari sebuah equipment dalam sistem perpipaan.
 
5. Ball Valve
Ball Valve adalah alternatif murah dari jenis valve-valve yang lain. Ball valve dengan menggunakan bola logam yang tengahnya ada lubang tembus, diapit oleh dudukan valve untuk dapat mengontrol aliran. Sering dipakai pada proses hydrocarbon, ball valve mampu untuk dapat mengatur besar kecil aliran gas dan uap terutama untuk tekanan rendah. Valve ini juga dapat dengan cepat ditutup dan cukup kedap untuk menahan fluida/ zat cair. Ball valve tidak menggunakan handwheel, tetapi dengan menggunakan ankle untuk dapat membuka atau menutup valve dengan sudut 90°.
 
6. Butterfly Valve
Butterfly Valve telah memiliki bentuk yang sangat unik jika dibandingkan dengan valve-valve yang lain. Butterfly dengan menggunakan plat bundar atau wafer yang dioperasikan dengan ankel untuk posisi membuka penuh atau menutup penuh dengan sudut 90°. Wafer ini tetap berada ditengah aliran, dan dihubungkan ke ankel melalui shaft. Saat valve dalam keadaan tertutup, wafer tersebut tegak lurus dengan arah aliran, sehingga aliran terbendung, dan saat valve terbuka wafer sejajar/ segaris dengan aliran, sehingga zat dapat mengalir melalui valve. Butterfly valve telah memiliki turbulensi dan penurunan tekanan (pressure drop) yang minimal. Valve ini sangat bagus untuk pengoperasian on-off ataupun throttling, dan bagus untuk dapat mengontrol aliran zat cair atau gas dalam jumlah yang besar. Namun demikian valve ini biasanya tidak memiliki kekedapan yang bagus, dan harus digunakan pada situasi/ sistem yang memiliki tekanan rendah (low-pressure).

7. Relief Valve
Relief valve telah memiliki fungsi yang sangat berbeda dari valve-valve yang lain. Valve ini telah didisain khusus untuk dapat melepas tekanan berlebih yang ada di equipment dan sistem perpipaan. Untuk dapat mencegah kerusakan pada equipment, dan lebih penting lagi cedera pada pekerja, relief valve dapat melepas kenaikan tekanan sebelum menjadi lebih ekstrim. Relief valve menggunakan pegas baja, yang secara otomatis akan terbuka jika tekanan mencapai level yang tidak aman. Level tekanan pada valve ini bisa diatur, sehingga bisa ditentukan pada level tekanan berapa valve ini akan terbuka. Ketika tekanan kembali normal, relief valve secara otomatis akan tertutup kembali.

Mr. King sang for the Drifters and found success as a solo performer with hits like “Spanish Harlem.”

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.
