Vacation at Ciwidey with ELEKTRO 08

My friends in department of electrical engineering ITB class of 2008 held a vacation at Ciwidey on July,17th-19th 2012. I came late to Ciwidey and followed my friend on July,18th because I had to finished some of my work first. I went to Ciwidey by chartering an angkot with 4 of my friends that come late too and arrived there in the morning. We stayed in two villas which is surrounded by tea farm. This is the location : -7.141851,107.382675This place was so pleasant. There are some tourism attraction that is near from  where we stayed such as Danau Situ Patengan, Kawah Putih, and Cimanggu. In the first day, my friends who had arrived early went to Danau Situ Patengan. I'm regret for not coming there. 
In the second day, when I arrived at Ciwidey, I enjoyed the morning air and nice atmosphere there immediately. Then, I had my breakfast and prepared to join a game with my friends in the pool.

The Villa

We played a game in the pool.

This is a video of the game.

In the afternoon, we went to Cimanggu Tourism near our villa. There are a hot water pool which also contain some minerals there but we just went to the woods behind it for jungle tracking. We were accompanied by a guide from Cimanggu. 

At the beginning of our walking in the woods some of my friends get a trouble when we decided to see the hot water spring. They walked on hot sludge and leaved their slippers on it. One of my friend lost one of his slippers so we and the guide helped him to find his slippers.

After we find his slippers, we continued our trip with different route. We were going to see the cool water spring at the top of the woods.

At night, we made grilled chicken.

We lit the fireplace before slept.

Making fried rice for breakfast.

In the afternoon we had to be checked out. Before we were back to ITB, we went to Kawah Putih. If we want to go to Kawah Putih we must pass through road uphill. It's better if you can use your own vehicle but the price will be high. So we used two cars from Kawah Putih administrator. On the way to Kawah Putih, suddenly a car that some of my friends and I rode had a trouble. It stopped when pass a ramp road. So, we had to wait for a new car on the way.

My crazy friends

What a nice vacation with my friends :)

Setting Up Next.js Project With ESLint, Typescript, and AirBnB Configuration

If we initiate a Next.js project using the  create-next-app tool, our project will be included with ESLint configuration that we can apply using yarn run lint . By default, the tool installs eslint-config-next and extends next/core-web-vitals in the ESLint configuration. The Next.js configuration has been integrated with linting rules for React and several other libraries and tools. yarn create next-app --typescript For additional configuration such as AirBnB, it is also possible. First, we need to install the peer dependencies of eslint-config-airbnb . We also add support for Typescript using eslint-config-airbnb-typescript . yarn add --dev eslint-config-airbnb eslint-plugin-import eslint-plugin-jsx-a11y eslint-plugin-react eslint-plugin-react-hooks yarn add --dev eslint-config-airbnb-typescript @typescript-eslint/eslint-plugin @typescript-eslint/parser After that, we can update the .eslintrc.json file for the new configuration. { "extends": [ "airb

Rangkaian Sensor Infrared dengan Photo Dioda

Keunggulan photodioda dibandingkan LDR adalah photodioda lebih tidak rentan terhadap noise karena hanya menerima sinar infrared, sedangkan LDR menerima seluruh cahaya yang ada termasuk infrared. Rangkaian yang akan kita gunakan adalah seperti gambar di bawah ini. Pada saat intensitas Infrared yang diterima Photodiode besar maka tahanan Photodiode menjadi kecil, sedangkan jika intensitas Infrared yang diterima Photodiode kecil maka tahanan yang dimiliki photodiode besar. Jika  tahanan photodiode kecil  maka tegangan  V- akan kecil . Misal tahanan photodiode mengecil menjadi 10kOhm. Maka dengan teorema pembagi tegangan: V- = Rrx/(Rrx + R2) x Vcc V- = 10 / (10+10) x Vcc V- = (1/2) x 5 Volt V- = 2.5 Volt Sedangkan jika  tahanan photodiode besar  maka tegangan  V- akan besar  (mendekati nilai Vcc). Misal tahanan photodiode menjadi 150kOhm. Maka dengan teorema pembagi tegangan: V- = Rrx/(Rrx + R2) x Vcc V- = 150 / (150+10) x Vcc V- = (150/160) x 5

Kerusakan pada Motherboard

1. Sering terjadi hang memory tidak cocok --- ganti memory ada virus di harddisk --- scan harddisk over clock --- seting kembali clock prosesor ada bad sector di harddisk --- partisi harddisk dengan benar 2. Pembacaan data menjadi lambat memori tidak cukup --- tambah memori harddisk penuh atau ada virus --- kurangi isi harddisk, scan harddisk, atau ganti hardisk 3. CMOS failure baterai habis --- ganti baterai CMOS seting BIOS berubah --- seting kembali BIOS 4. Tidak bisa booting cache memory rusak --- disable eksternal cache memory di BIOS memori tidak cocok --- ganti memori boot sector pada harddisk rusak --- masukkan operating system baru ada bad sector pada trek awal harddisk --- partisi harddisk 5. Suara bip panjang berkali-kali memori rusak --- periksa kedudukan memori memori tidak cocok --- ganti memori memori tidak masuk slot dengan sempurna --- periksa kembali kedudukan memori 6. Suara bip bagus tetapi tidak ada tampilan / bip dua kali VGA card

Raspberry Pi Bluetooth Connection

Raspberry Pi 3 provides a built-in Bluetooth module. The latest Raspbian has been bundled with tools for enabling Bluetooth connection. The Bluetooth icon will be shown up on the top right corner of the desktop. It's a tool to discover available Bluetooth devices and connect Pi with Bluetooth devices. It is easy to connect any Bluetooth-enabled electronic device with Pi. But, sometimes Pi will fail to connect, especially for Bluetooth device that has no standardized services. From a terminal, we can use the  bluetoothctl tool to scan and connect with a Bluetooth device. You should make sure that the BlueZ protocol stack has been installed by running $ apt-get install bluez Run bluetoothctl to enter the tool command window Turn the power on by running power on (Optional) You can set AutoEnable=true in /etc/bluetooth/main.conf if you want to make the Bluetooth auto power-on after reboot. Run devices to see which devices have been paired Run scan on if your desired d

Pemrograman Paralel dengan CUDA

CUDA ( Compute Unified Device Architecture ) adalah suatu skema yang dibuat oleh NVIDIA agar NVIDIA selaku GPU ( Graphic Processing Unit ) mampu melakukan komputasi tidak hanya untuk pengolahan grafis namun juga untuk tujuan umum. Jadi, dengan CUDA, kita dapat memanfaatkan cukup banyak  processor  yang dimiliki oleh NVIDIA untuk berbagai perhitungan. GPU yang ada  saat ini seperti ATI pun sudah memiliki banyak processor di dalamnya. Pada ATI, skema yang mereka bangun disebut ATI Stream. Saat ini pemrograman paralel menjadi sangat penting karena kebutuhan kemampuan komputasi komputer yang terus meningkat seperti kemampuan multitasking  dan pengolahan grafis yang andal. Metode saat ini dalam peningkatan peforma komputer juga berbeda dengan masa lampau dimana peningkatan clock  dari processor  yang diutamakan. Peningkatan clock  juga dibatasi oleh kemampuan fisik dari perangkat digital yaitu persoalan daya dan panas. Pada 2005 berbagai industri komputer mulai menawakan komputer den
