 HYDROELECTRIC POWER

Dams are what people most associate when it comes to hydroelectric power. Water flows through the dam’s turbines to produce electricity, known as pumped-storage hydropower. Run-of-river hydropower uses a channel to funnel water through rather than powering it through a dam.

Benefits

Hydroelectric power is very versatile and can be generated using both large scale projects, like the Hoover Dam, and small scale projects like underwater turbines and lower dams on small rivers and streams. Hydroelectric power does not generate pollution, and therefore is a much more environmentally-friendly energy option for our environment.

Current Limitations

Most U.S. hydroelectricity facilities use more energy than they are able to produce for consumption. The storage systems may need to use fossil fuel to pump water.[3]  Although hydroelectric power does not pollute the air, it disrupts waterways and negatively affects the animals that live in them, changing water levels, currents, and migration paths for many fish and other freshwater ecosystems.


How Hydroelectric Work


Parts of a Hydroelectric Plant

Most conventional hydroelectric plants include four major components (see graphic below):

  1. Dam. Raises the water level of the river to create falling water. Also controls the flow of water. The reservoir that is formed is, in effect, stored energy.
  2. Turbine. The force of falling water pushing against the turbine's blades causes the turbine to spin. A water turbine is much like a windmill, except the energy is provided by falling water instead of wind. The turbine converts the kinetic energy of falling water into mechanical energy.
  3. Generator. Connected to the turbine by shafts and possibly gears so when the turbine spins it causes the generator to spin also. Converts the mechanical energy from the turbine into electric energy. Generators in hydropower plants work just like the generators in other types of power plants.
  4. Transmission lines. Conduct electricity from the hydropower plant to homes and business.

Now all we need to do is a little mathematics. Engineers have found that we can calculate the power of a dam using the following formula:

Power = (Height of Dam) x (River Flow) x (Efficiency) / 11.8

PowerThe electric power in kilowatts (one kilowatt equals 1,000 watts).
Height of DamThe distance the water falls measured in feet.
River FlowThe amount of water flowing in the river measured in cubic feet per second.
EfficiencyHow well the turbine and generator convert the power of falling water into electric power. For older, poorly maintained hydroplants this might be 60% (0.60) while for newer, well operated plants this might be as high as 90% (0.90).
11.8Converts units of feet and seconds into kilowatts.

For the dam in our area, lets say we buy a turbine and generator with an efficiency of 80%.

Then the power for our dam will be:

Power = (10 feet) x (500 cubic feet per second) x (0.80) / 11.8 = 339 kilowatts

To get an idea what 339 kilowatts means, let's see how much electric energy we can make in a year.

Since electric energy is normally measured in kilowatt-hours, we multiply the power from our dam by the number of hours in a year.

Electric Energy = (339 kilowatts) x (24 hours per day) x (365 days per year) = 2,969,000 kilowatt hours.

The average annual residential energy use in the U.S. is about 3,000 kilowatt-hours for each person. So we can figure out how many people our dam could serve by dividing the annual energy production by 3,000.

People Served = 2,969,000 kilowatts-hours / 3,000 kilowatt-hours per person) = 990 people.

My Goal, My Ambition



Dreams and real life are two sides of human life. That said, many things that happen in the real world start from dreams.

    Every human being has the confidence and ability to realize the dreams he/she has planned since long ago. People's dreams develop along with the needs and realities they face. He realized that with his persistence in that goal could produce the dreams he wanted. It doesn't matter how big or small our dreams are, everything is determined by the strength of desire. Humans living in this world must have a purpose. Humans who do not have it all will be confused about living their lives.

    Dreams for me have the meaning of someone's hope for their future, dreams have different meanings for everyone, many think dreams are dreams that are very difficult to achieve, in fact this is not entirely true, because a dream can definitely be achieved if we try seriously- really in order to be achieved. There are those who think dreams are just dreams, but there are also people who think that as their life goals, having dreams can give them the enthusiasm to continue to move forward to carry out this life so that it can become self-development. However, we certainly agree that reaching for the dream of a coveted future is not as easy as snapping fingers. Many obstacles must be overcome.

Then, what is my dream?




    My name is Muhammad Derbyanoe Lexa Justicio. My doubts about physics and mathematics have grown since I was a child. I spent a lot of my childhood studying a fair amount of science. Also, when I was a child, I liked to read biographies of famous figures. From scientists to well-known figures such as historians, presidents and many more, I like to read them.

    I don't know why, but when I was studying mathematics and physics, my head which slowly turned a little dizzy and eyes that heated up due to forgetfulness gave me a special pleasure. Some people consider it all torture, but not for me. It's all a gift. Gift can learn and enjoy certain effects while you studying something.



    I've always dreamed of becoming a great person, greater than the third President of Indonesia, BJ Habibie. That's no prolem, right? I want to become an engineer and advance Indonesia, my country, in the field of technology. But just like other children, I also often have different ideals, sometimes I want to become a doctor, an architect, even a police officer. But as time went by, I was able to determine what I should do in my future.



    Now I am in high school. The high school where I studied is one of the best schools in Indonesia. With each passing day, my desire to make my dreams become stronger.



    After high school, I wanted to study at the Bandung Institute of Technology or find a scholarship to study abroad. While I'm in college, I also want to build a business with my friends so that my life doesn't depend solely on my parents.

   


     I want to go to school as high as possible, and become an engineer. Not only an engineer, a professor. I want to become a minister for State-Owned Enterprises (BUMN), like Eric Thohir. I really want to fix the State-Owned Enterprises in Indonesia.



   When my dream has come true, I want to be able to help other people realize their dreams. When I am successful enough, I really want to be able to send orphans to school. I often feel sorry for the orphans. I want to become a regular donor to an orphanage / foundation, or even establish a foundation,

    I will try to achieve all of my dreams and make them come true. When all my dreams come true, I will dedicate them all to the happiness of my parents, because without them I would not be able to make it all happen.

NICOS WEG - REVIEW

REVIEW


 

Hi everyone, this time I will review Nicos Weg movie. Happy reading!


This movie is the first German language movie that I watched. It took a long time to understand this movie. This movie tells the story of a young man named Nico who goes on vacation to Germany. Nico from Spanish, so for him, Germany is still quite foreign. 

Honestly, this film is a film that is suitable to watch with family. This film makes it easier for us to learn German, especially for film lovers. Nico's story, maybe it can be an illustration when we go to Germany with quite a bit of language understanding. More or less, I have to open a dictionary in order to understand the meaning of this film. However, still, this film is really able to convey German language learning properly.

The story begins, when Niko went to Germany for a vacation to meet his aunt. While at the airport, Nico experienced something surprising and troublesome. Without realizing it, his bag disappeared. Nico, who was careless, was confused about how to get her bag back. Luckily, Niko got help from one of the German peoples. However, it turns out that finding Niko's bag is not as easy as it seems. Many things happened. For more details, friends can watch the film, Link below.

Nicos Weg

Maybe I will talk about the advantages and disadvantages of this film, before we get into the advantages and disadvantages, I just want to remind you that this is my only opinion. It could be, my taste in film is much different from the taste of your friends' films.

Advantages of Film

The advantages in this film are quite a lot, starting from the light plot, to the way of speaking the words which can be said to be easy to understand. What I should appreciate is how the director and scriptwriter put the value of the German language in this film. This is very rare, how can you include the material that must be conveyed in this film. I also appreciate how the players play their respective roles. Almost all actors and actresses play very beautifully. Especially the character Nico, really can be relied on to be the main character. Can become the best actor when he was confused, trying to joke with the small children around him, and how he reacted to the situation really felt very real. Of course, not everyone is capable of doing it. A few scenes are also enough to let us know the tricks of learning German. Sticking paper on an object, for example, it really did not occur to me. And it looks like I'll start doing it.


Disadvantages of Film

The flaws in this film are actually quite a few. I think the shortcomings of this film are the first, how to take pictures. You could say, the shooting in this film is not optimal. Mainly, to present a scene that seems and should be able to appear even more beautiful. Because in my opinion, there are a lot of scenes with less attractive backgrounds. Not a big promblem actually, however, enough to bother my mind for a moment. Second, some scenes show how to speak quite quickly. It's not that fast, however, for me who is just learning German, it is a bit of a hassle. The plot of this film feels a little boring, because in my opinion, this film is classified as having a very, very flat plot. There is no rhythm that can make the audience stare and on the contrary, there are a lot of algorithms that make the audience a little sleepy.


The words that still ring in my ears are "schön" somehow, even today, the word "schön" is still in my head. Difficult words? Obviously there is, but it can be overcome because I am always accompanied by my favorite dictionary.


Maybe that's all I can review this time, 

Thanks

Review Film Sultan Agung, Film Sejarah Kebanggaan Hanung Bramantyo

Film Sultan Agung adalah film karangan sutradara terkenal yang tidak perlu diragukan lagi keahlian dalam membuat film. Yap! Hanung Bramantyo. Sutradara kelahiran Yogyakarta ini berhasil menggarap film sejarah berjudul "Sultan Agung: Tahta, Perjuangan, Cinta" dan mememperoleh lebih dari satu juta penonton di layar kaca. Meskipun sudah banyak orang yang membahas film ini, saya ingin membahasnya leih dalam di tahun 2020.


Sinopsis Film


Setelah ayahnya, Panembahan Hanyokrowati wafat, Raden Mas Rangsang yang masih remaja menggantikannya dan diberi gelar Sultan Agung Hanyakrakusuma. Ini adalah sebuah tanggung jawab yang tidak mudah. Sultan Agung harus menyatukan adipati-adipati di tanah Jawa yang tercerai berai oleh politik VOC yang dipimpin oleh Jan Pieterszoon Coen, di bawah panji Mataram. Di sisi lain, ia harus mengorbankan pula cinta sejatinya kepada Lembayung dengan menikahi perempuan ningrat yang bukan pilihannya.


Proses Produksi


Dalam proses pembuatannya, Hanung telah menyiapkan segalanya. Mulai dari lokasi, hingga dialog jawa yang amat sangat halus "krama" telah dipersiapkan dengan sangat matang. Hanung juga telah memilih aktor dan aktris yang tepat untuk memainkan perannya masing - masing. Meskipun demikian, sebagian orang menganggap beberapa aktror dan atau aktris dinilai kurang cocok dan fasih dalam berbahasa jawa. Lokasi yang dipilih sebagai tempat syuting film juga sangat cocok dan dinilai memukau.


Pengenalan Tokoh yang Sangat Baik

Pada pembukaan film, penonton disuguhkan masa muda Raden Mas Rangsang (Marthino Lio) di padepokan tempat ia menuntut ilmu agama dan ilmu lainnya yang ditinggalkan oleh Kanjeng Sunan Kalijaga dan diajar oleh Ki Jejer (Deddy Sutomo).
Selain itu, penonton juga disajikan dengan kisah cinta Raden Mas Rangsang dan Lembayung (Putri Marino)yang cukup unik dan menarik. Ada beberapa scene yang dapat menghibur penonton dengan keseruan dan kelucuannya. 

Menurut saya, ini suatu inovasi baru dari film karya Hanung Bramantyo. Dalam bagian pembukaan, Marthino Lio, PutriMarino,dan Deddy Sutomo mampu mengantarkan penonton ke suasana zaman mataram dengan bahasa jawa yang sangat baik dan cukup memukau. Saya sempat dibuat kagum dengan akting Putri Marino yang benar - benar menguasai karakter spenuhnya.
Hanung berhasil menambahkan detail - detail dimana bagi sebagian orang, hal tersebut merupakan hal penting dan tak boleh dilewatkan. Kita juga akan disuguhkan dengan keindahan Mataram masa lampau.


Keunggulan

Film ini menumbuhkan mental perjuangan anak bangsa. Mengingat, film ini dibuat sesuai dengan catatan sejarah. Hanung bramantyo dengan berani dan percaya diri menyuguhkan film yang sangat jarang sekali diminati orang ( dalam proses produksinya). Watak dari Hnung Bamantyo sebagai seorang sutradara ternama yang punya cara sendiri dalam mengendalikan Martinho Lio dan Adinia Wirasti sangatlah hebat. Mereka tampil memukau di layar kaca dan menuai banya sekali pujian. 
Scene peperangan dan konflik yang terjadi dapat menjadi pelajaran penting bagi kita semua. Selain itu, Hanung mampu membuat film ini benar - benar bernilai dengan pesan moral yang ada di dalamnya. Beberapa aktor dan aktris juga dapat menjadi karakte yang ditokohkan dengan baik. Mengingat, berperan menjadi anggota dari keraton haruslan penuh kehati - hatian. Oleh karena itu, saya mengapresiasi pemeran dan semua tim yang telah bekerja sama dalam pembuatan film ini.


Kekurangan


Setiap film tidak bisa terhindar dari yang namanya kesalahan dan lain sebagainya. Film ini dinilai kerap kali menampilkan adegan yang terlalu dramatis. Atau biasa disebut dramatisasi yang terlalu berlebihan. Sehingga, sekilas saya mengira ini film yang sedikit terlalu memaksa. 
Penggunaan bahasa jawa oleh beberapa tokoh juga dinilai terlalu kaku. Sehingga, hampir tidak sesuai dengan logat khas orang jawa. Ditambah dengan kurang gregetnya akting dari beberapa pemeran seperti: Adinia Wirasti (Lembayung dewasa) dan Christine Hakim (Ibu RM Rangsang)
Scene kematian Jan Pieterszoon Coen yang kurang memuaskan dan dinilai terlalu memaksa sangatlah mengganggu.


Rating

Film ini sangat cocok ditonton oleh kalangan remaja. Dengan demikian, para remaja bisa menghargai dan banyak belajar dari perjuangan Sultan agung di film ini. Meskipun terdapat beberapa kekurangan, tapi tetep kok Overall film ini kece.
Score: 8,5/10

THE ORIGINS OF SURABAYA

SURABAYA

A long time ago in East Java there were two strong animals, Sura and Baya. Sura was a shark and Baya was a crocodile. They lived in the sea. Actually, they were friends. But when they were hungry, they were very greedy. They did not want to share their food. They would fight for it and never stop fighting until one of them gave up. It was a very hot day. Sura and Baya were looking for some food. Suddenly, Baya saw a goat. 
Yummy, this is my lunch,” said Baya.

“No way! This is my lunch. You are greedy! I had not eaten for two days!” said Sura.
Then Sura and Baya fought again. After several hours, they were very tired. Sura had a plan to stop their bad behavior.
“I’m tired of fighting, Baya,” said Sura.
Me too. What should we do to stop fighting? Do you have any idea?” asked Baya. 

Yes, I do. Let’s share our territory. I live in the water, so I look for food in the sea. And you live on the land, right? So, you look for the food also on the land. The border is the beach, so we will never meet again. Do you agree?” asked Sura. 
Hmm... let me think about it. OK, I agree. From today, I will never go to the sea again. My place is on the land,” said Baya.

Then they both lived in the different places. But one day, Sura went to the land and looked for some food in the river. He was very hungry and there was not much food in the sea. Baya was very angry when he knew that Sura broke the promise.
“Hey, what are you doing here? This is my place. Your place is in the sea!”
“But, there is water in the river, right? So, this is also my place!” said Sura.  Then Sura and Baya fought again. They both hit each other. Sura bite Baya's tail. Baya did the same thing to Sura. He bit very hard until Sura finally gave up. He went back to the sea. Baya was very happy. He had his place again.
The place where they were fighting was a mess. Blood was everywhere. People then always talked about the fight between Sura and Baya. They then named the place of the fight as Surabaya, it’s from Sura the shark and Baya the crocodile. People also put their war as the symbol of Surabaya city.

THIS IS NOT AN ORDINARY HOLIDAY STORY

My Holiday Experience

Last holiday, me and my family went to Kediri. We visited many coffee shop there and build a convection business.

We went to Kediri Town. Why? because in Kediri Town there is my grand'ma house. Because my grand'ma house is quite big and large, me and my brother play football together. After we play football together, me and my brother usually invite my family to watch movies in cinema. In another day, me, my brother, and my sister play with our old friends. Sometimes we went to cinema, coffee shop, and each other. In the middle of the night, my brother and i had an idea to build a convection business. Because we have the same goal, The HWAT APPAREL finally formed.

I don't know why, but I think that was great idea. With HWAT APPAREL, I can get income while studying. And as a student i will not be disturbed. Because we want to market the product, we arranged a meeting with old friends and influential people that we will offer cooperation with our product. This is not as easy as imagined, negotiating with old friends and influential people is very difficult an takes a lot of time. Finally, HWAT APPAREL officially opened on the first of January 2020. 

This is not an ordinary holiday story. This is a holiday story that turned into a HWAT APPAREL story. I hope HWAT APPAREL can develop rapidly as times go by.

CHEETAH

CHEETAH

Image result for gambar cheetah
Kingdom:Animalia
Phylum:Chordata
Class:Mammalia
Order:Carnivora
Family:Felidae
Genus:Acinonyx
Scientific Name:Acinonyx jubatus
Common Name:Cheetah
Cheetah Classification and Evolution
The Cheetah is a large and powerful feline that was once found throughout Africa and Asia and even in parts of Europe. Today however, it is found in only a few remote regions of its once vast natural range, primarily due to growing Human settlements and the hunting of them for their fur. There are widely considered to be five different subspecies of Cheetah that vary only very slightly in colouration and are most easily distinguished by their geographic location. Although they are not considered to be part of the 'big cat' family as they cannot roar, Cheetahs are one of Africa's most powerful predators and are most renowned for their immense speed when in a chase. Capable of reaching speeds of more than 60mph for short periods of time, the Cheetah is the fastest land mammal in the world.

Cheetah Anatomy and Appearance
The Cheetah has a long and slender body that is covered in coarse yellowish fur and dotted with small black spots. Its long tail helps with balance and changing direction quickly and unlike the rest of the Cheetah's body, there are ringed markings along the tail which ends in a black tip. Cheetahs have small heads with high set eyes that aid them when surveying the surrounding grasslands for potential prey. They also have distinctive black "tear marks" that run from the inner eye, along their nose and down to the outside of their mouths, which are thought to help protect them from being blinded by the bright sun. The exceptional speed of the Cheetah is caused by a number of things including having strong and powerful hind legs, and an incredibly flexible and muscular spine which allows the Cheetah to not only sprint quickly but also makes them very agile. They also have non-retractable claws which dig into the ground, giving the Cheetah better grip at high speed.

Cheetah Distribution and Habitat
The Cheetah once had a vast historical range that stretched across a number of continents, but their distribution today is much more scattered with a small number found in Iran and the majority found in sub-Saharan Africa. Although Cheetahs are still found in a few different parts of eastern and southern Africa, the highest population of wild Cheetahs is now found in Namibia in south-western Africa. Cheetahs are most commonly found stalking prey on the vast, open grasslands but they are also found in a variety of other habitats as well including deserts, dense vegetation and mountainous terrain, providing that there are both adequate supplies of food and water. Cheetahs are one of Africa's most vulnerable felines with population numbers being mainly affected by growing Human settlements that encroach on their native habitats.

Cheetah Behaviour and Lifestyle
The Cheetah is unique amongst Africa's felines primarily because they are most active during the day, which avoids competition for food from other large predators like Lions and Hyenas that hunt during the cooler night. They are also one of the more sociable Cat species with males often roaming in small groups, generally with their siblings, and oddly enough, it is the females that are more solitary animals apart from the 18 months or so that they spend looking after their cubs. Cheetahs are fiercely territorial animals that patrol large home ranges and often overlap those of other Cheetahs, and indeed Lions, with females tending to roam across a much larger range than males. They are typically shy and very stealthy animals so that they are able to hunt for prey in the hot daylight hours without being spotted so easily.

Cheetah Reproduction and Life Cycles
After a gestation period that lasts for around 3 months, the female Cheetah gives birth to between two and five cubs that are born blind and incredibly vulnerable in the African wilderness. The cubs suckle from their mother for the first few months when they begin eating meat, and start to accompany her on hunting trips as they are able to learn how to hunt from watching her. Cheetah cubs learn the majority of their hunting techniques through playing with their siblings, and remain with their mother until they can hunt successfully and leave to find their own territory at between 18 months and 2 years old. Sadly, one of the main reasons for such drastic declines in Cheetah numbers is that up to 75% of Cheetah cubs don't live to be older than 3 months, as their mother has to leave them every day to find food to feed them, leaving the vulnerable cubs helpless in the face of predators.

Cheetah Diet and Prey
The Cheetah has exceptional eyesight and so hunts using sight by first stalking its prey (from between 10 to 30 meters away), and then chasing it when the time is right. Cheetahs often kill their prey in vast open spaces but tend to drag it into a hiding place to prevent it from being scavenged by other animals. The Cheetah has to do this as it cannot eat its prey straight away, due to the fact that they are immensely hot after the chase and need time to cool down before they can feast. Cheetahs are carnivorous animals meaning that they only hunt and kill other animals in order to get the nutrition that they need to survive. They mainly hunt large herbivores including Gazelle and a number of large Antelope species such as Wildebeest, along with Zebras and smaller mammals like Hares. The exact diet of the Cheetah though tends to depend on its location.

Cheetah Predators and Threats
The adult Cheetah is a dominant predator in its environment and is therefore not seen as prey (more as competition) by other large predators. The Cheetah cubs however, are incredibly vulnerable particularly when their mother is off hunting, and are preyed upon by a number of animals including Lions and Hyenas, but also large avian species such as Eagles and Vultures. The biggest threat to Cheetahs is people, who have not only taken vast areas of its natural habitat for themselves, but have also turned large regions of land into National Parks. Although these areas seem to be showing increases in both Lion and Hyena populations, Cheetah numbers are much lower as there is more competition for food with the increasing numbers of these other large predators.

Cheetah Interesting Facts and Features
One of the most distinctive differences between the different subspecies is that their fur colour changes slightly, depending on their surrounding environment. Those Cheetahs found in the more arid desert regions tend to be lighter and have smaller spots than the King Cheetahs that roam the south African grasslands, and are darker, slightly bigger and have larger spots. Although Cheetahs cannot roar, they do make a variety of different sounds including a high-pitched yelp which can be heard for more than a mile away. The Cheetah is one of the most distinctive of the world's felines and although it is fairly commonly confused with the Leopard, its name is thought to have come from the Hindu word 'chita' which means the 'spotted one'.

Cheetah Relationship with Humans
Despite their fierce appearance, Cheetahs have actually been domesticated by local people for thousands of years, as they were used to help with hunting for food for the villagers. They have also been kept in captivity for a long time, but as they do not seem to produce particularly healthy individuals, wild Cheetahs were regularly caught to restore the bloodline. Hunted by people as trophies throughout much of their natural range, Cheetahs have completely disappeared from numerous places and along with habitat loss to growing Human settlements and the clearing of land for agriculture, Cheetah numbers are still declining rapidly in many areas today.

Cheetah Conservation Status and Life Today
Today, the Cheetah has been listed by the IUCN as a species that is Vulnerable from extinction in its natural environment in the near future. Habitat loss along with the increase of natural parks that are home to a large number of competing predators has led to drastic declines in the world's Cheetah population. There are now estimated to be between 7,000 and 10,000 individuals left in the wild, along with a growing number being found in zoos and animal institutes all over the world.
