Hemat Energi Dengan Blackle si Google Hitam

http://www.blackle.com/

Blackle? Apa yang pertama kali yang anda pikirkan ketika mendengar nama tersebut. Si hitam? atau kehitaman?

Nah bagi yang belum tahu, sekadar informasi dari Kandank Ilmu Blackle adalah Google dalam versi hitam, jadi background pencarian Google semuanya berwarna hitam.

Sebenarnya buat apa sih Google mengeluarkan versi hitam dari dirinya itu? Tujuannya adalah untuk melakukan penghematan energi.. Menurut penelitian yang diambil oleh Google dari sebuah tulisan di blog pada tahun 2007 silam, bahwa sebuah halaman situs dengan penuh warna putih akan membutuhkan daya 74 watt untuk tampil apalagi sebuah situs yang penuh gambar dan warna [Kandank Ilmu tidak salah satunya] sementara situs yang penuh warna hitam hanya membutuhkan 59 watt saja.

Berapa penghematan yang dilakukan Blackle? Sampai saat ini [5:55PM] Blackle telah menghemat 1,325,387.321 Watt hours saved.

Kalo kita mau melakukan pengujian terhadap penghematan Blackle misalkan aja begini dengan tampilan awal Google berwarna putih yang kira-kira mendapat 200 juta kunjungan per hari. Asumsikan halaman utama tersebut ditampilkan rata-rata selama 10 detik, artinya Google dijalankan sekitar 550 ribu jam setiap hari pada PC yang sama. Misalkan setiap pengguna menjalankan Google pada tampilan layar penuh, perubahan ke latar belakang hitam akan menghemat 15 (74-59) watt. Hal itu akan menghasilkan penghematan 8,3 MegaWatt-jam per hari atau sekitar 3000 Megawatt-jam per tahun.

Ternyata jumlah energi yang bisa dihemat dari si Blackle ini signifikan juga ya. Tapi Blackle hanya bisa digunakan untuk melakukan pencarian web saja tidak bisa melakukan pencarian gambar [kalo ada pencarian gambar ntar ga hemat energi] kelemahan lain karena hasil pencarian ditampilkan dalam background hitam mungkin bagi kita akan kesulitan sedikit dalam melihat hasil pencarian. [bisa pakai Ctrl+A] supaya semua tulisannya kelihatan.

Mari kita semua mulai hemat energi dari hal kecil pada pencarian di dunia maya!! Yang mau mencoba Blackle silahkan dicoba di http://www.blackle.com/

How is Blackle saving energy?

Blackle was created by Heap Media to remind us all of the need to take small steps in our everyday lives to save energy. Blackle searches are powered by Google Custom Search.

Blackle saves energy because the screen is predominantly black. "Image displayed is primarily a function of the user's color settings and desktop graphics, as well as the color and size of open application windows; a given monitor requires more power to display a white (or light) screen than a black (or dark) screen." Roberson et al, 2002

In January 2007 a blog post titled Black Google Would Save 750 Megawatt-hours a Year proposed the theory that a black version of the Google search engine would save a fair bit of energy due to the popularity of the search engine. Since then there has been skepticism about the significance of the energy savings that can be achieved and the cost in terms of readability of black web pages.

We believe that there is value in the concept because even if the energy savings are small, they all add up. Secondly we feel that seeing Blackle every time we load our web browser reminds us that we need to keep taking small steps to save energy.

How can you help?

We encourage you to set Blackle as your home page. This way every time you load your Internet browser you will save a little bit of energy. Remember every bit counts! You will also be reminded about the need to save energy each time you see the Blackle page load.

Help us spread the word about Blackle by telling your friends and family to set it as their home page. If you have a blog then give us a mention. Or put the following text in your email signature: "Blackle.com - Saving energy one search at a time".

Have a look at our energy saving tips page for ideas on steps you can take to save energy or you can follow Blackle on Twitter and we will keep you updated with simple energy saving tips.

There are a lot of great web sites about saving energy and being more environmentally friendly. They are full of great tips covering the little things that we can all do to make a difference today.

10 Ways to Go Green for Student from Kandank Ilmu

As a student, here are plenty of small things you can do to help the environment. Here are 10 simple ideas.

What ecofriendly things can a college student do to help the environment? More than you might think, actually. The typical student's lifestyle can lead to quite a bit of waste, especially paper, so small steps to conserve and recycle can really add up! Here are 10 environmentally friendly tips from Kandank Ilmu for a greener student life.

1. Recycle Everything, Especially Paper! Think about how many pieces of paper you go through in a semester. There's your class notes, your scrap copies, your term papers, your daily school newspapers, and assorted stuff that you've printed out from the Internet... it all adds up. Look for a paper recycle bin on campus-- you might find one near a dormitory or large classroom building. And recycle other items as well, including cans, bottles, and cardboard boxes.
2. Walk or Ride Your Bike and Limit Your Use of a Car. If you have to go somewhere close consider riding your bike or walking there instead of your car. It's better on the environment and healthier. Ask yourself if you really need a car as a college student, because if you can get by without one, you can save a good deal of money on gas, repairs, and overpriced student car insurance. If you do own a car, try to use it as little as you can.
3. Buy Green. Buy recycled products whenever you can, especially paper. Buy environmentally safe cleaning products as well. Some of these products cost more-- but many don't, or the price difference is negligible.
4. Use Your Printer Wisely. You can save paper by printing on both sides of the page. Many lecturers don't mind if you turn in a paper like this-- just ask first. Save pages that you've printed and use the backs to print out drafts and other things you don't have to turn in. In addition, many printers have multiple settings for print quality. Use the high quality print setting for things that have to look nice, but use the low quality setting for things that don't. This will save ink. While you're at, consider cutting down on the things your print out. Do you really need to print out that web page, or can you just bookmark it?
5. Start a Blog or Website. Through a blog or website, you can get homework help, submit discussion questions, and play with interactive study guides, all of which save paper.
6. Use Refillable Binders Instead of Notebooks. This is a simple way to save waste. If you want to save your notes after the semester is over, take them out of the binder and staple them. Or you can go electronic and take all of your notes on a laptop.
7. Use recycled paper: All teachers go through a ton of notebooks and papers each year, so using recycled paper and then recycling all your files after the year is over will positively impact the environment.
8. Use PowerPoint: Start creating PowerPoint presentations to deliver notes, photos and study guides without wasting paper.
9. Join the Group. Join the courses group such as ESDAL, KEBEKIN and others. Most of them provide soft copy for your courses. So, no more hard copies just soft copies.
   
10. E-mail other teachers and administration: If your school hasn’t already, try to start an e-mail only campaign that eliminates needing hard copies of substitute requests, field trip proposals and meeting RSVPs.

Lembaga Penelitian dan Pengabdian pada Masyarakat (LPPM) Universitas Padjadjaran (Unpad) in partnership with The Swedish Institute held public lecture with “Climate Change and The Future of Energy” theme. Presenting Prof. Christian Azar from Chalmers University of Technology (Swedia). The public lecture held in Bale Rumawat Padjadjaran, Kampus Iwakoesoema Soemantri, Jl. Dipati Ukur No. 35 Bandung, Thursday (19/02).

Ir. Chay Asdak M.Sc., Ph.D. (secretry of LPPM Unpad) in his opening key note said that climate change issue is a big issue that need to be discussed and find a new way to tackle this issue. “These issue will be more discuss about public lecture and things more about the future energy,” he said. Also present in this event the Director of Cooperation Unpad, Ramdan Panigoro, MD., M.Sc., Ph.D., a few other guests and students from Unpad.

Through his presentation, Prof. Azar shows that climate change is felt to have started since 1980 ago. Prof. Christian predict, when the 100 years we can reduce the use of emissions it will be a positive influence on the temperature of the earth. "The impacts are temperature increase, sea level rise, more Intense precipitation, droughts, and a lot of uncertainty remains," said Prof. Azar.

Prof. Azar shows us some solution what Swedish government did to minimize the climate change;

1. Use less energy
2. Use less forms of energy
3. Capture and store carbon
4. District heating system
   

“Basically if we want to use a new energy in the future, then we must to leave a traditional way like coals, metals, etc,”

Kandank Ilmu = Sahabat Bumi (Penghematan minimal Rp 3 juta per semesternya)

"Jadilah Sahabat Bumi"

Adalah slogan yang digunakan oleh Kompas Muda dalam kompetisi yang mereka adakan dengan tajuk "Kompetisi Website Kompas MuDa - IM".

Pemanasan global (global warming) yang mengancam bumi semakin terasa dampaknya. Suhu kota Bandung yang semaking panas, melelehnya es di kutub selatan dan utara, dan banyak lagi. Sudah saatnya kita sebagai generasi muda untuk lebih aktif melakukan upaya penyelamatan dan pencegahan bumi dari bahaya kerusakan yang lebih parah lagi.

Di balik lahirnya Kandank Ilmu tersimpan salah satu upaya besar yang kami lakukan. Yaitunya mengurangi ketergantungan akan kertas dan beralih ke pemanfaatan teknologi informasi. Berdasarkan riset yang kami lakukan, dengan beralihnya bank soal manual ke online, Kandank Ilmu menghemat lebih kurang Rp 1.5 juta per ujian. Ini dengan asumsi bahwa 50% mahasiswa biasanya memfotokopi bank soal beralih ke bank soal online. (Data yang kami ambil berdasarkan laporan peserta ujian dari FE UNPAD untuk jurusan ESP saja). Berarti untuk semester ganjil ini saja Kandank Ilmu menghemat Rp 3 juta dengan asumsi yang sama (50% mahasiswa). Ketika asumsi kita ubah menjadi 75% maka penghematan yang telah dilakukan oleh Kandank Ilmu adalah sebesar Rp 4.5 juta.

Kedepannya, Kandank Ilmu akan terus berkomitmen menjadi SAHABAT BUMI dengan menjadi "kandang" ilmu yang peduli akan bumi. Komitmen ini kami harapkan akan memudahkan mahasiswa untuk mendapatkan pemahaman tentang mata kuliah disamping upaya penyelamatan bumi oleh generasi muda.
