Explanation Text

TSUNAMI The term of “tsunami” comes from the Japanese which means harbour (“tsu”) and wave (“nami”). A tsunamigk is a series of waves generated when water in a lake or the sea is rapidly displaced on a massive scale. A tsunami can be generated when the sea floor abruptly deforms and vertically displaces the overlying water. Such large vertical movements of the earth’s crust can occur at plate boundaries. Subduction of earthquakes are particularly effective in generating tsunamis, and occur where denser oceanic plates slip under continental plates. As the displaced water mass moves under the influence of gravity to regain its equilibrium, it radiates across the ocean like ripples on a pond. Tsunami always bring great damage. Most of the damage is caused by the huge mass of water behind the initial wave front, as the height of the sea keeps rising fast and floods powerfully into the coastal area.

My Last Holiday

Last holiday, I went to Cikole Adventure Treetop with my friends. First, we gathered at Bazar 3. At Bazar, we talked together while waiting the others to come. It was so fun. After all my friends came, we went to Cikole by car. But, two of my friends went there by motorcycle. Wr went there at 9 a.m. On the way, we talked together, we laughed, and that was a quality time! After arrived at Cikole, we didn't play. We just took some photos, sat together while talked and shared things. After from Cikole, we went to Sindang Reret at 12 p.m. Then, we rode ATV. That was very very fun. Although our clothes were dirty because of mud, but it's alright because we really enjoyed it. After finished playing at Sindang Reret, we ate at Ayam Brebes Lembang. It was very exciting. After finished eating, we came back to SMAN 3 at 2.30 p.m. We arrived at SMAN 3 at 3.30 p.m. It was really fun!
On 31th of December 2013, I celebrated new year's eve with my family and my cousin. We went to Suis Butcher at 10 pm. On the way, we saw so many people waited for 2014 to come. I always love go out at the new year's eve because it's always a lot of fireworks and so many people played trumpet.
After arrived at Suis Butcher, we ate together, we shared things, we talked, we laughed. It was very fun and that was a quality time. After finished eating, we continued to go around Bandung. The street was full of people. After that, we came back to my house. In my house, we saw fireworks with my family. It was amazing. After that, we slept at 1.30 a.m.

Amazing Place : Raja Ampat

The oceanic natural resources around Raja Ampat give it significant potential as a tourist area. Many sources place Raja Ampat as one of their top ten most popular places for diving whilst it retains the number one ranking in terms of underwater biodiversity.
According to Conservation International, marine surveys suggest that the marine life diversity in the Raja Ampat area is the highest recorded on Earth. Diversity is considerably greater than any other area sampled in the Coral Triangle composed of Indonesia, Malaysia, Philippines, Papua New Guinea, Solomon Islands, and Timor-Leste. The Coral Triangle is the heart of the world's coral reef biodiversity, making Raja Ampat quite possibly the richest coral reef ecosystems in the world.
The area's massive coral colonies along with relatively high sea surface temperatures, also suggest that its reefs may be relatively resistant to threats like coral bleaching and coral disease, which now jeopardize the survival of other coral ecosystems around the world. The Raja Ampat islands are remote and relatively undisturbed by humans.
The high marine diversity in Raja Ampat is strongly influenced by its position between the Indian and Pacific Oceans, as coral and fish larvae are more easily shared between the two oceans. Raja Ampat's coral diversity, resilience, and role as a source for larval dispersal make it a global priority for marine protection.
1,508 fish species, 537 coral species (a remarkable 96% of all scleractinia recorded from Indonesia are likely to occur in these islands and 75% of all species that exist in the world), and 699 mollusk species, the variety of marine life is staggering. Some areas boast enormous schools of fish and regular sightings of sharks, such as wobbegongs.
Although accessing the islands is not that difficult, it takes some time. It takes six hours flight from Jakarta, the capital city of Indonesia to Sorong. Then, taking a boat to reach the islands is necessary.

Descriptive Text : Rubik's Cube

Rubik's cube is a toy puzzle designed by Erno Rubik, an architect and professor at the University of Budapest. It is a cube-shaped and contains of smaller cube pieces with six sides having different colors. The cube was so popular during the 1980s, and at its peak between 1980 and 1983. 200 million cubes were sold world wide. In the solved condition, Rubik’s cube has six faces which all of the colors are same. The Rubik's cube has red, yellow, blue, green, white, and orange color. The edges and corners move when the cube is rotated and the cube becomes scrambled. The challenge of the puzzle is to solve each cube to the original position.

There are many solutions to solve the Rubik’s cube. Lars Petrus, Jessica Fridich, and Shotaro Makisumi, are people who created the solution to solve it. A common solution used by cubers was developed by Jessica Fridrich, a professor at the Department of Electrical and Computer Engineering at Binghamton University. It uses a large number of algorithms, especially for orienting and permuting the last layer. The cross consists of one color is done first and then continue to make second and first layer by F2L (First 2 Layer) algorithms that consist of 41 algorithms. The next step is to solve the third layer by OLL (Oriented Last Layer) and PLL (Permutation Last Layer). Fridrich's solution requires learning roughly 120 algorithms but the Cube can be solved in only 55 moves on average.

There are two kinds of Rubik’s cube, DIY and Original Rubik’s cube. DIY (Do It Yourself) Rubik’s cube is the cube that can be assembled and modified by ourselves. The core of it made up of bolts; so we can arrange the bolts to get a comfortable Rubik’s cube. Types of DIY Rubik’s cube are, A type, C type, and F type. Every type has different advantages for cubers. For the example, F type is a lightweight Rubik’s cube and it almost can’t be pop out. It is suitable for a stylish cuber. C type has a good material and it suitable for a rush cuber. The second type is Original Rubik’s cube or we can call Ori Rubik. Ori Rubik is the cube that can’t be assembled or modified by ourselves. The core of this made of nails. Ori Rubik is suitable for a beginner cuber that’s training their fingertrick.

 

Biography : Bill Gates

He is consistently ranked in the Forbes list of the world's wealthiest people and was the wealthiest overall from 1995 to 2009—excluding 2008, when he was ranked third; in 2011 he was the wealthiest American and the world's second wealthiest person. According to the Bloomberg, Billionaires List, Gates is the world's richest person in 2013, a position that he last held on the list in 2007.
During his career at Microsoft, Gates held the positions of CEO and chief software architect, and remains the largest individual shareholder, with 6.4 percent of the common stock.  He has also authored and co-authored several books.

Gates is one of the best-known entrepreneurs of the personal computer revolution. Gates has been criticized for his business tactics, which have been considered anti-competitive, an opinion which has in some cases been upheld by the courts. In the later stages of his career, Gates has pursued a number of philanthropic endeavors, donating large amounts of money to various charitable organizations and scientific research programs through the Bill & Melinda Gates Foundation, established in 2000^.
Gates stepped down as chief executive officer of Microsoft in January 2000. He remained as chairman and created the position of chief software architect for himself. In June 2006, Gates announced that he would be transitioning from full-time work at Microsoft to part-time work, and full-time work at the Bill & Melinda Gates Foundation. He gradually transferred his duties to Ray Ozzie, chief software architect, and Craig Mundie, chief research and strategy officer. Gates's last full-time day at Microsoft was June 27, 2008. He remains at Microsoft as chairman.
