>Uang Giral Sebagai Pengganti Uang Kartal


Real money disappearing in Japan

Por kirai el 31 de May de 2007 en Technology

At the beginning of 2001 Suica IC card started to work in Japan, it is an e-money card based on IC technology exploited by JR (Japan Railways). At the beginning it was used only to pay train travles, but nowadays you can use it in many traditional shops, convenience stores and even vending machines. From some months ago Suica is compatible with other IC cards (PASMO is the name of one of them), right now in Japan there are around 20 million users who have the “same type” of electronic wallet. That’s huge! That mass helps a lot to expand it through new businesses and start becoming really useful for everyone, blahblahblah… next you can see a video showing how I use my Suica to pay a train travel:

Look how fast people enters, payment with IC cards is very fast and allows a high flux of people entering and exiting from train stations. You just have to approach your wallet to pay.

The same thing you saw in the video you can do it with a mobile phone, just put your mobile phone next to the reader and you pay. IC Cards inside mobile phones are already being used by millions of Japanese.

Paying in a supermarket just approaching your mobile phone.

For example, today I tried to live without “real money”. In the morning I used the train and the bus, I paid both with my IC card. At lunch I had to pay with “real money” in a restaurant :(. Then I bought some snacks in a convenience store with the IC card, also got a drink from a vending machine with the IC card. When I went back home I payed everything at the supermarket just approaching my wallet to the reader. Except the restaurant, everything was electronic money!

The future is a combination of electronic wallet, credit card and mobile phone. Something similar is what Docomo is trying to do right now with his latest technologies. Some of the things that you can already do (or will be able to in the short term) are: bank transfers, buying with your mobile phone without pain, you can pay something you found on the Internet with your laptop just approaching your mobile to the computer (Many new Japanese laptops have an IC reader by default), you can transfer money to other mobile phone, buy/sell stocks, use your phone as a “normal” credit card, pay plane tickets using your phone in the airport… Here is the picture that explains it as Docomo sees the future:

IC reader in a laptop.

Suica IC reader in a shop.

And this is the security system:

That little black thing is “the key”. If the key is farther away than two meters from phone, then it blocks. For example, if someone steals your handbag with your mobile phone inside, if you have the black little key in your pocket the robber won’t be able to use the phone, it will be blocked.

I don’t know you, but for me “analog”|”real” money makes no sense in the world we live nowadays. Can you imagine living without coins in your pocket? I hate coins!


>Home wiring as antenna


House acts as its own antenna

U. WASHINGTON (US)— Scientists have developed a device that uses a home’s electrical wiring as a giant antenna.

The sensors use the wiring to transmit information to and from almost anywhere in the home, allowing for wireless sensors that run for decades on a single watch battery.

Low-cost sensors recording a building’s temperature, humidity, light level, or air quality are central to the concept of a smart, energy-efficient home that automatically adapts to its surroundings.

But that concept has yet to become a reality.

“When you look at home sensing, and home automation in general, it hasn’t really taken off,” says Shwetak Patel, assistant professor of computer science and of electrical engineering at the University of Washington.

“Existing technology is still power hungry, and not as easy to deploy as you would want it to be.”

That’s largely because today’s wireless devices either transmit a signal only several feet, Patel says, or consume so much energy they need frequent battery replacements.

Patel’s team has devised a way to use copper electrical wiring as a giant antenna to receive wireless signals at a set frequency.

A low-power sensor placed within 10 to 15 feet of electrical wiring can use the antenna to send data to a single base station plugged in anywhere in the home.

The Sensor Nodes Utilizing Powerline Infrastructure device originated when Patel and co-author Erich Stuntebeck were doctoral students at Georgia Tech and discovered that home wiring is an efficient antenna. Since then, Patel’s team has built the actual sensors and refined this method.

Gabe Cohn, a UW doctoral student tested the system in a 3,000-square-foot house. He tried five locations in each room and found that only 5 percent of the house was out of the system’s range, compared to 23 percent when using over-the-air communication at the same power level.

While traditional wireless systems have trouble sending signals through walls, this system actually does better around walls that contain electrical wiring.

Most significantly, SNUPI uses less than 1 percent of the power for data transmission compared to the next most efficient model.

The existing prototype uses UW-built custom electronics and consumes less than 1 milliwatt of power when transmitting, with less than 10 percent of that devoted to communication.

Depending on the attached sensor, the device could run continuously for 50 years, much longer than the decade-long shelf life of its battery.

Longer-term applications might consider using more costly medical-grade batteries, which have a longer shelf life.

The team is also looking to reduce the power consumption even further so no battery would be needed. They say they’re already near the point where solar energy or body motion could provide enough energy.

The researchers are commercializing the base technology, which they believe could be used as a platform for a variety of sensing systems.

Another potential application is in health care. Medical monitoring needs a compact device that can sense pulse, blood pressure or other properties and beam the information back to a central database, without requiring patients to replace the batteries.

Pram: Sudah Waktunya Dibuat UU Kerukunan Umat Beragama
Laurencius Simanjuntak – detikNews

Jakarta – Wakil Ketua DPR Pramono Anung mengemukakan sudah saatnya dibentuk UU Kerukunan Umat Beragama sebagai pengganti Surat Keputusan Bersama (SKB) 2 Menteri. Sebelumnya, sejumlah kalangan, parpol, LSM, dan pengamat juga mendesak DPR untuk menyusun UU tersebut.

"Sudah waktunya dibentuknya UU Kerukunan Umat Bergama, sehingga tidak lagi diatur oleh peraturan menteri," kata Pramono di Gedung Parlemen, Senayan, Jakarta, Kamis (16/9/2010).

Menurut Pram, sapaan akrabnya, kerukunan umat beragama yang diatur lewat SKB, menemukan titik yang merisaukan. Yakni dengan adanya multitafsir terhadap salah satu pasal yang mengatur persyaratan pendirian rumah ibadah.

"Disebutkan meminta persetujuan warga di sekitar tempat beribadah. Ini menjadi multitafsir, bahwa memberi peluang siapapun yang mayoritas untuk menentukan," kata mantan Sekjen PDI Perjuangan ini.

Pram menambahkan, sudah menjadi tugas Menteri Agama untuk menyelasaikan persoalan multitafsir atas regulasi tersebut. Ke depan, katanya, regulasi yang mengatur kerukunan umat beragama harus sesuai dengan pasal 29 UUD 1945.

"Bahwa negara menjamin setiap warga negara untuk memeluk dan beribadah sesuai agamanya. Negara yang tanggung jawab, bukan kelompok yang menentukan," kata dia.

Seluruh SPBU Yang Dites GM Kandungan Sulfurnya Ketinggian

Syubhan Akib – detikOto

Jakarta – Produsen mobil General Motors pada bulan Juli 2010 lalu melakukan uji terhadap sampel Premium di 10 SPBU di Jakarta. Hasilnya cukup mencengangkan, seluruh sampel Premium memiliki kadar sulfur atau belerang di ambang batas.

Premium produksi Pertamina dibuktikan memiliki kadar sulfur yang kelewat tinggi, lebih tinggi dari batas yang ditentukan yakni maksimal pada 0,05 % wt, yang tertuang dalam aturan Dirjen Migas 3674K/24/DJM/2006.

Dari sampel Premium yang diambil di SPBU daerah Kebon Nanas ditemukan kandungan sulfur hingga 0,0631 % wt sementara di daerah Mampang ditemukan kadar sulfur sebesar 0,0629 % wt.

Selain di kedua tempat tadi, sampel juga diambil di daerah Cakung, Klender, Ciganjur, Bekasi Timur dan Narogong. Bensin di semua tempat ini diketahui memiliki kandungan sulfur yang sedikit di atas ketentuan yang berlaku.

Nah yang paling tinggi kandungan sulfurnya ternyata ada di SPBU yang khusus melayani angkutan umum seperti taksi Taxiku dan Cipaganti.

Dari 3 sampel yang diambil di 3 SPBU khusus itu ditemukan kandungan sulfur yang lebih tinggi lagi yakni di sekitar angka 0,8 % wt. Mungkin ini yang bisa menjadi jawaban fenomena jebolnya fuel pump masyarakat dan taksi.

Sementara untuk kandungan oktan, SPBU di daerah Cakung diketahui memiliki kandungan oktan yang lebih rendah dari batas yang ditetapkan yakni Ron 88. Di Cakung, kandungan oktan hanya sampai diangka Ron 87,8. 

"Kadar sulfur tidak bagus untuk logam, dalam mesin injeksi, sulfur ini merusak, karena itu harus dibatasi," ujar After Sales Director PT General Motors AutoWorld Indonesia Suwadji Wirjono.

GM melakukan tes sampel premium ini dengan bantuan Core Laboratories yang memang memiliki laboratorium analisis untuk minyak. Total ada 9 tes yang diujikan kepada Premium.

Selain kandungan sulfur, sampel Premium juga diuji dengan mengetes tingkat korosi bensin dengan Copper strip corrosion, tingkat volatilitas bensin dengan metode reid vapor pressure, dan analisis lainnya, seperti kandungan timbal, washed gum. Selain kandungan sulfur, untuk tes yang lain tidak terlalu melampaui ambang batas.

Namun sejauh ini, Pertamina masih meyakini tidak ada yang salah dalam kandungan Premiumnya.

>Menkominfo paksa RIM blokir konten pornografi


BlackBerry Ditutup kalau Tak Blokir Pornografi

JAKARTA, KOMPAS.com — Menteri Komunikasi dan Informatika (Menkominfo) Tifatul Sembiring mengancam untuk menutup layanan BlackBerry di Indonesia bila penyedia layanannya, Research in Motion (RIM), menolak untuk memblokir konten pornografi.

"Kami sudah memanggil RIM yang sudah bekerja sama dengan enam operator di Indonesia," kata Tifatul di Jakarta, Selasa (31/8/2010).

Ia mengatakan, bila ternyata konten pornografi internet masih dapat diakses melalui BlackBerry, pihaknya akan dengan tegas memberikan teguran kepada pabrikan ponsel pintar tersebut.

Bahkan, Menteri menyatakan tidak akan segan-segan menutup layanan BlackBerry di Indonesia bila RIM menolak memblokir konten pornografi.

"Kita minta mereka menutup konten pornografi, kalau tidak, dia yang akan kita tutup di sini (Indonesia)," kata Menteri.

Pemblokiran situs porno, menurut Menteri, merupakan amanah Undang-Undang Nomor 44 Tahun 2008 tentang Pornografi, khususnya Pasal 18 dan 19. Pasal itu pada intinya mengamanatkan bahwa pemerintah memiliki kewenangan untuk melakukan pemutusan jaringan pembuatan dan penyebarluasan produk pornografi atau jasa pornografi, termasuk pemblokiran pornografi melalui internet.

"RIM harus menaati aturan itu, kalau tidak, itu berarti mereka melanggar undang-undang kita," katanya.
