Ada 5 elemen penting yang juga harus diperhatikan dalam menentukan kesuksesan suatu pengecatan yaitu :

1. Pilihlah cat yang berkualitas
Dengan menggunakan cat yang bermutu, akan dapat mempermudah Anda dalam pengerjaannya, memberikan daya tutup yang lebih baik, dan telah memiliki daya tahan yang lebih lama. Karakter penting lainnya yang menentukan kualitas suatu cat adalah : daya rekat, daya sebar, scrub resistance (daya tahan terhadap gosokan ), burnish resistance ( daya tahan dari terbakar ), serta mudah dibersihkan dari noda. Cat yang berkualitas adalah yang menggunakan bahan - bahan yang ramah lingkungan, tidak menggunakan tambahan merkuri dan timah hitam yang mempunyai dampak berbahaya bagi manusia dan lingkungan.

2. Gunakan peralatan pengecatan yang baik
Peralatan yang baik akan dapat membuat persiapan permukaan dan proses pengaplikasian cat lebih mudah dan aman. Kuas dan rol yang bermutu akan dapat menghasilkan permukaan yang lebih halus, dan tidak meninggalkan bristles ( gelembung -gelembung kecil ), sehingga dapat mempercepat waktu pengerjaan. Peralatan lain yang penting adalah tangga yang kokoh dengan pegangan tangan untuk keamanan Anda.

3. Persiapkan permukaan yang akan dicat dengan benar
Cat juga merupakan suatu lapisan yang sangat tipis. Oleh karena itu keberhasilan suatu pengecatan sangat ditentukan oleh persiapan permukaan yang benar. Perbaikilah kondisi tembok seperti retak - retak atau berlubang, sebelum Anda mengecat. Juga kondisi kelembaban serta kebersihan tembok harus Anda perhatikan.

4. Tutupi ruangan atau permukaan yang  tidak ingin dicat
      Anda akan dapat mengerjakan proses pengecatan dengan lebih cepat, tanpa harus kuatir akan noda/bercak -bercak cat, dimeja, kursi, gagang pintu dan barang-barang lainnya. Juga akan mempercepat dan memper-mudah proses pembersihan setelah mengecat.

5. Lakukan pengecatan pada kondisi cuaca yang baik
Untuk bisa mendapatkan hasil yang terbaik. ikuti selalu petunjuk yang direkomendasikan oleh produsen cat mengenai suhu maksimum dan minimum, serta tingkat kelembaban udara yang disarankan.Untuk pengecatan dianjurkan dilakukan pada saat cuaca cerah dan tidak di musim huian .

 

MANADO, Saco-Indonesia.com - Sampai dengan pagi ini, Kamis (16/1/2014), bencana banjir bandang yang terjadi di enam kabupaten/kota di Sulawesi Utara, Rabu kemarin, telah merenggut 13 korban tewas, dan dua warga lainnya belum ditemukan.

MANADO, Saco-Indonesia.com - Sampai dengan pagi ini, Kamis (16/1/2014), bencana banjir bandang yang terjadi di enam kabupaten/kota di Sulawesi Utara, Rabu kemarin, telah merenggut 13 korban tewas, dan dua warga lainnya belum ditemukan. Sementara, tercatat 40 ribu warga mengungsi.

Seperti yang telah diberitakan, banjir terjadi di enam kabupaten/kota di Sulut secara bersamaan, yaitu Kota Manado, Minahasa Utara, Kota Tomohon, Minahasa, Minahasa Selatan, dan Kepulauan Sangihe.

Menurut Sutopo Purwo Nugroho, Kepala Pusat Data Informasi dan Humas BNPB, bencana ini terjadi akibat kombinasi antara faktor alam dan antropogenik yang memicu terjadinya banjir bandang dan longsor yang masif di Sulawesi Utara.

Sutopo menguraikan, di Kota Manado lima tewas, satu orang hanyut belum ditemukan (Veber Sony Lowing). Di Kota Tomohon lima orang tewas. Di Minahasa tiga orang tewas, satu orang hilang (Niko-54), dan satu orang luka berat.

Di Kabupaten Minahasa Utara tiga desa dengan 1.000 jiwa terisolasi akibat banjir dan longsor. Di Kepulauan Sangihe beberapa rumah tertimbun longsor. Diperkirakan, sekitar 40.000 warga mengungsi ke tempat yang aman. 

Sutopo menjelaskan, hujan deras dipicu sistem tekanan rendah di perairan selatan Filipina, menyebabkan pembentukan awan intensif. Selain itu, adanya konvergensi dampak dari tekanan rendah di utara Australia, awan-awan besar masuk ke wilayah Sulut.

Akibatnya, empat sungai besar di Kota Manado meluap dan menghanyutkan puluhan rumah dan kendaraan. Bencana kali ini lebih besar daripada sebelumnya yang pernah terjadi pada tahun 2000 yang menyebabkan 22 tewas, dan Februari 2013 yang menyebabkan 17 tewas.

HOBART, Tasmania — Few places seem out of reach for China’s leader, Xi Jinping, who has traveled from European capitals to obscure Pacific and Caribbean islands in pursuit of his nation’s strategic interests.

So perhaps it was not surprising when he turned up last fall in this city on the edge of the Southern Ocean to put down a long-distance marker in another faraway region, Antarctica, 2,000 miles south of this Australian port.

Standing on the deck of an icebreaker that ferries Chinese scientists from this last stop before the frozen continent, Mr. Xi pledged that China would continue to expand in one of the few places on earth that remain unexploited by humans.

He signed a five-year accord with the Australian government that allows Chinese vessels and, in the future, aircraft to resupply for fuel and food before heading south. That will help secure easier access to a region that is believed to have vast oil and mineral resources; huge quantities of high-protein sea life; and for times of possible future dire need, fresh water contained in icebergs.

It was not until 1985, about seven decades after Robert Scott and Roald Amundsen raced to the South Pole, that a team representing Beijing hoisted the Chinese flag over the nation’s first Antarctic research base, the Great Wall Station on King George Island.

But now China seems determined to catch up. As it has bolstered spending on Antarctic research, and as the early explorers, especially the United States and Australia, confront stagnant budgets, there is growing concern about its intentions.

China’s operations on the continent — it opened its fourth research station last year, chose a site for a fifth, and is investing in a second icebreaker and new ice-capable planes and helicopters — are already the fastest growing of the 52 signatories to the Antarctic Treaty. That gentlemen’s agreement reached in 1959 bans military activity on the continent and aims to preserve it as one of the world’s last wildernesses; a related pact prohibits mining.

But Mr. Xi’s visit was another sign that China is positioning itself to take advantage of the continent’s resource potential when the treaty expires in 2048 — or in the event that it is ripped up before, Chinese and Australian experts say.

“So far, our research is natural-science based, but we know there is more and more concern about resource security,” said Yang Huigen, director general of the Polar Research Institute of China, who accompanied Mr. Xi last November on his visit to Hobart and stood with him on the icebreaker, Xue Long, or Snow Dragon.

With that in mind, the polar institute recently opened a new division devoted to the study of resources, law, geopolitics and governance in Antarctica and the Arctic, Mr. Yang said.

Australia, a strategic ally of the United States that has strong economic relations with China, is watching China’s buildup in the Antarctic with a mix of gratitude — China’s presence offers support for Australia’s Antarctic science program, which is short of cash — and wariness.

“We should have no illusions about the deeper agenda — one that has not even been agreed to by Chinese scientists but is driven by Xi, and most likely his successors,” said Peter Jennings, executive director of the Australian Strategic Policy Institute and a former senior official in the Australian Department of Defense.

“This is part of a broader pattern of a mercantilist approach all around the world,” Mr. Jennings added. “A big driver of Chinese policy is to secure long-term energy supply and food supply.”

That approach was evident last month when a large Chinese agriculture enterprise announced an expansion of its fishing operations around Antarctica to catch more krill — small, protein-rich crustaceans that are abundant in Antarctic waters.

“The Antarctic is a treasure house for all human beings, and China should go there and share,” Liu Shenli, the chairman of the China National Agricultural Development Group, told China Daily, a state-owned newspaper. China would aim to fish up to two million tons of krill a year, he said, a substantial increase from what it currently harvests.

Because sovereignty over Antarctica is unclear, nations have sought to strengthen their claims over the ice-covered land by building research bases and naming geographic features. China’s fifth station will put it within reach of the six American facilities, and ahead of Australia’s three.

Chinese mappers have also given Chinese names to more than 300 sites, compared with the thousands of locations on the continent with English names.

In the unspoken competition for Antarctica’s future, scientific achievement can also translate into influence. Chinese scientists are driving to be the first to drill and recover an ice core containing tiny air bubbles that provide a record of climate change stretching as far back as 1.5 million years. It is an expensive and delicate effort at which others, including the European Union and Australia, have failed.

In a breakthrough a decade ago, European scientists extracted an ice core nearly two miles long that revealed 800,000 years of climate history. But finding an ice core going back further would allow scientists to examine a change in the earth’s climate cycles believed to have occurred 900,000 to 1.2 million years ago.

China is betting it has found the best location to drill, at an area called Dome A, or Dome Argus, the highest point on the East Antarctic Ice Sheet. Though it is considered one of the coldest places on the planet, with temperatures of 130 degrees below zero Fahrenheit, a Chinese expedition explored the area in 2005 and established a research station in 2009.

“The international community has drilled in lots of places, but no luck so far,” said Xiao Cunde, a member of the first party to reach the site and the deputy director of the Institute for Climate Change at the Chinese Academy of Meteorological Sciences. “We think at Dome A we will have a straight shot at the one-million-year ice core.”

Mr. Xiao said China had already begun drilling and hoped to find what scientists are looking for in four to five years.

To support its Antarctic aspirations, China is building a sophisticated $300 million icebreaker that is expected to be ready in a few years, said Xia Limin, deputy director of the Chinese Arctic and Antarctic Administration in Beijing. It has also bought a high-tech fixed-wing aircraft, outfitted in the United States, for taking sensitive scientific soundings from the ice.

China has chosen the site for its fifth research station at Inexpressible Island, named by a group of British explorers who were stranded at the desolate site in 1912 and survived the winter by excavating a small ice cave.

Mr. Xia said the inhospitable spot was ideal because China did not have a presence in that part of Antarctica, and because the rocky site did not have much snow, making it relatively cheap to build there.

Anne-Marie Brady, a professor of political science at the University of Canterbury in New Zealand and the author of a soon-to-be-released book, “China as a Polar Great Power,” said Chinese scientists also believed they had a good chance of finding mineral and energy resources near the site.

“China is playing a long game in Antarctica and keeping other states guessing about its true intentions and interests are part of its poker hand,” she said. But she noted that China’s interest in finding minerals was presented “loud and clear to domestic audiences” as the main reason it was investing in Antarctica.

Because commercial drilling is banned, estimates of energy and mineral resources in Antarctica rely on remote sensing data and comparisons with similar geological environments elsewhere, said Millard F. Coffin, executive director of the Institute for Marine and Antarctic Studies in Hobart.

But the difficulty of extraction in such severe conditions and uncertainty about future commodity prices make it unlikely that China or any country would defy the ban on mining anytime soon.

Tourism, however, is already booming. Travelers from China are still a relatively small contingent in the Antarctic compared with the more than 13,000 Americans who visited in 2013, and as yet there are no licensed Chinese tour operators.

But that is about to change, said Anthony Bergin, deputy director of the Australian Strategic Policy Institute. “I understand very soon there will be Chinese tourists on Chinese vessels with all-Chinese crew in the Antarctic,” he said.

 

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.
