Catatan Khan Academy

Normative statement  (diukur secara norma ) adalah pernyataan yg bersifat opini dan tdk bisa diukur.
Contoh: pernyataan memberi tunjangan pada org miskin yg tdk bekerja membuat org jadi malas.

Positive statement adalah pernyataaan yg bisa diukur.
Misalnya: menaikkan pajak thd org kaya klan menaikkan pertumbuhan ekonomi.

Saat para ahli membuat penelitian atau theory mrk selalu menyederhanakan masalah, yg sebenarnya tdk sesimple itu dlm dunia nyata. Inilah yg disebut Ceteris Paribus.
Ceteris Paribus adalah asumsi bhw hy faktor yg diteliti yg berubah yg berhubungan) sedangkan yg lain dianggap konstan/ tdk terpengaruh.

Sistem ekonomi:
Command Economy/ ekonomi komando/terpusat.
Contoh komunis Uni Soviet 
Negara menentukan apa yg diproduksi, seberapa byk dan siapa yg akan dpt.

Market economy/ekonomi liberal.
Pasar yg menentukan brg apa yg diproduksi, brp byk. Sistem ini mendorong org creative krn mrk akan mendapat reward atas penemuannya dan kerja kerasnya.

Mixed economy adalah campuran dr kedua sistem di atas.
Contoh USA meskipun cenderung liberal tapi negara masih memegang beberapa bidang yg penting (public ownership)

Aneka info

                      Tips membuat juice lemon:


Terapi minum lemon tiap pagi sewaktu perut masih kosong byk dijalankan orang krn meski jeruk perasan lemon ini asam tapi karena sifatnya asam basa, maka aman dikonsumsi bhk bagi org yg sakit maag.

Solusi lemon dg air panas ini bhk juga memiliki banyak kegunaan spt terapi mengatasi maag, anti bakteri dan terapi yg ampuh atasi batuk.

Agar tidak memeras lemon tiap hari (selama terapi... juga jangan berlebihan atau meminum lemon juga tdk boleh durasi terlalu lama)
1 kg lemon jika dijuicer dg kulitnya akan menghasilkan 500/600ml lemon murni
Jika juicer Anda tidak menghasilkan ampas yg kering, gunakan kain utk memeras ampas yg masih basah.

Taruh perasan lemon ini dlm wadah kaca, masukkan dlm kulkas. Setiap akan minum, ambil sendok plastik dan larutkan 3 sendok jus lemon ini dg air hangat.


                                   Tips mencuci anggur

Saya paling malas kalau cuci anggur.... kalau tidak mencuci setiap butirnya serasa makan anggur yg masih blm bersih.
Krn harus mencuci tiap butirnya di bwh air mengalir dan rasanya makan banyak waktu.

Saya suka sekali sewaktu menemukan di situs internet yg mengajarkan cara praktis cuci anggur. Dan dijelaskan juga sistem pencucian ini membuat anggur bebas dari pestisida.

Link nya sbb
https://lifehacker.com/wash-grapes-quickly-with-baking-soda-and-salt-1682442493

Caranya adalah:
1. Cuci anggur di bawah air mengalir...secara global saja
2. Larutkan 1 sendok makan baking soda dan dua sendok makan garam dg air.
3.Rendam anggur dkm air soda dan garam tadi selama 15 menit
4. Bilas dg air mengalir dan bilas lagi dg air minum.
Tidak perlu menggosok setiap butirnya,anggur sdh cukup bersih dan siap dikonsumsi....

Tips memerangi batuk
1. 3 sdm air lemon dicampur rebusan sirih, campur air hangat.
2. Minum ramuan no 1 harus dijarakin dg obat dokter sekitar 2 jam.
3. Bisa diselingi dg sari kunyit yg dicampur rebusan sirih.

4. Minum air hangat utk mengurangi gatal tenggorokan.




Bawang Goreng Krispi

Yuk dengerin krispinya di video di atas

Hasil tampilan bawang goreng
250 gr bawang mentah sth digoreng menjadi 115gram bwang goreng.
Jadi 1 kilo bawang iris akan menjadi 460gram

Agar krispi:
bawang jgn dicuci,
tambahkan satu atau 2 sdm ke bawang sblm digoreng
Minyak harus cukup banyak shg seluruh bawang tenggelam







Bikin Kripik Kentang Serut
1 kilo kentang setelah digoreng menjadi 230 gram kripik



Perut begah karena asam lambung, minum 1 sendok makan kecap asin

Summary To Kill A Mocking Bird by Phoebe


TO KILL A MOCKING BIRD

BY: HARPER LEE

Summarized by: Phoebe Keziah


“Lawyers, i suppose, were children once.”—Charles Lamb

This story is narrated by Jean Louise Finch, or nicknamed Scout, a little girl who lives in Maycomb, Alabama with her older brother, Jem and their widowed dad, Atticus. They also live with a black cook named Calpurnia. Atticus works as a laywer for a living, and they live in the main residential road.
 When Scout was nearly six and Jem almost ten, they befriended a boy named Charles Baker Harris, or Dill, who comes by every summer, and so the three played together every summer. Dill became interested in a spooky house that belongs to the Radleys. Inside the house lived a man named Arthur Radley, or Boo, and his brother Nathan.  Mr. Nathan always went outside, on the contrary, Boo had never gone outside in years. Now Scout, released from school thirty minutes before Jem, always ran by the Radleys.
One day she saw something shining from a hole in an oak tree, and it turned out to be a piece of gum. And the days passed there was always something in the hole. One night Jem and Dill decided to go to the Radleys, with Scout.  But they stood in horror when a shadow made its way towards them. When the shadow returned to the house, Jem ran towards Scout and a shot was heard. The shot stirred up a commotion and Jem lost his pants in the run. Later that night, Jem decided to go back to the Radleys and found his pants folded and stitched up.
The next winter, they kept finding gifts in the oak tree hole, until eventually Mr. Nathan Radley filled the hole up with cement. A while after, their neighbour’s house caught fire. While watching the fire, someone slipped a blanket onto Scout’s shoulders. Atticus said someday Scout would have to thank Boo Radley for the blanket.

Atticus, doing his job as a laywer, agrees to defend a black man, Tom Robinson, accused to raping and beating a white girl named Mayella Violet Ewell. She had bruises on her neck and her right part of her face that usually will tend to show that a left-handed man could easily do this. Scout, Jem and Dill were in the court all day long watching Atticus fight for Tom’s liberty. But hearing Tom’s side of the story, it was actually Mayella who wanted Tom to sleep with her. It turned out that Mayella’s father is ambidextrous, and Tom didn’t have a left arm because an incident when he was a boy. Atticus fought for Tom all day long, but it was up to the juries now. The juries had a long discussion but in the end the votes made Tom guilty. Tom was put in prison and later shot to death trying to escape.
It was Halloween and the school made an original pageant about what Maycomb county agricultural products were. Scout was supposed to be a Ham and when the teacher called Po-ork she would go out the stage. After the pageant, Jem and Scout walked home. When they reached the Radleys- it was clear because the ground beneath Scout’s feet felt cold that meant they were under the oak tree- Someone was following them! Jem shouted to Scout to run but the ham costume made it hard to move in the dark. Then she heard a crunching sound and Jem’s scream. Scout ran with all her might and sunk herself into a stomach. “Uff!” said its owner while he tried to catch her hands, but the Ham costume saved her. Scout managed to run away from him. And there was another man that carried Jem, arm broken and now unconscious to Atticus’ house.
When Atticus called the doctor and let him examined Jem, the Sherriff arrived. “Jem’s arm will heal quickly” said the doctor. Scout, then, told them about the incidents that occurred that night.
Atticus asked who’d brought Jem to the house, and Scout looked at the man who was leaning against the wall. “Hey, Boo.” she said. It was Arthur Radley that saved Jem.
 The Sherriff took a look at the man whom they left at the Radleys. It was Bob Ewell, Mayella’s father, lying on the ground with a knife stuck between his ribs, drunk and dead, because he fell on his own knife. Boo asked Scout to take him home so Scout escorted Boo home. Then she crawled up at Atticus’ lap and fell asleep.


My opinion about this book:
This story happened when white people discriminated black people, so the juries let their views be biased by the prejudice. So this book is called “TO KILL A MOCKINGBIRD” because it means “to kill something/one innocent”.

Yaitu melalui (-1,4) dan (6,1)

                   y2 - y1.  
           m =  x2- x1   6- (-1)

                    1-4
                      7
         
                    -3/7
Jadi jawabannya C
                    
2. Dengan membuat segitiga yg menghubungkan kedua titik tsb.















































Jika dua garis sejajar maka gradiennya sama.
https://buatgueajah.blogspot.com/search?q=Gradien (lihat catatan yg di bagian bawah ya..)
 Gradien garis g adalah
m = y/x   
m = 2/1
m =2 (karena garis miring ke kiri maka gradiennya -)
Jadi gradiennya -2

Sekarang masukkan (0,6) ke persamaan dg gradien -2.
Y-y1= m (x-x1)
Y- 6 = -2(x-0)
Y-6 = -2x +0
 Y = -2x+6
Jadi jawabannya A

























Perhatikan setiap 200.000 keuntungannya 80.000
Jadi 900.000/200.000 x 80.000
       = 9/2 x 80.000
       = 360.000
Jadi jawabannya C

20. Diketahui sistem persamaan 4x- y =18 dan
3x+2y = 19, Nilai 4x + 7y =...
A. -27
B. 27
C. 34
D. 43
Gunakan eliminasi
4x - y =18.    Eliminasi y, kalikan persamaan dg2
3x +2y = 19

8x - 2y = 36
3x +2y = 19 +
11x      = 55
    X=5

Masukkan x = 5 ke persamaan 4x - y =18.
20 - y =18, y=2

X=5, y=2 masukkan ke 4x+7y
                                           20+14=34, jadi jawabnnya C




Ingat pr8nsip sudut pelurus dan sudut sehadap.
78° dan 6x adalah sudut pelurus jika dijumlah 180°
6x dan 3x adalah sudut sehadap, maka besarnya SAMA.



































CAD adalah sudut pelurus, jadi alfa + teta =180











































Gunakan prinsip pythagoras
15^2+8^2 = sisi miring^2
225 + 64 = 289
Sisi miring = √289 =17

Sisi miring yg pendek
6^2+8^2= sisi miring yg pendek ^2
36 +64 =100
Sisi miring yg pendek =√100=10

Keliling= 17x2 + 10x2
                =34+ 20
                 =54

PR=2r =2.10=20
PQ=16
PR^2=PQ^2+QR^2
20^2=16^2+QR^2
400= 256+QR^2
QR^2 =400-256
QR^2=144
QR=12
Maka QT adalah 0,5x12=6
Segitiga QST adalah siku2, gunakan pythagoras
Qs^2=QT^2+ST^2
10^2=6^2+ ST^2
100=36+ST^2
100=36+ST^2
ST^2=64=8

Learn from human calculator

Learn addition, substraction from the left, not from the right from the human calculator.

Why? Because that is the way our brain actually works.
Please see the video below...

This method is also adopted by professor Yohanes Surya from Indonesia. His way of teaching is called Matematika Gasing.

Summary of seven habits book




The book begins with the frustration of the writer that was successful in his work but had failed to keep the married life warm and intact. His work had distanced him from fulfilling the emotional needs that the family required.

At one point in his life, his work requested him to handle a project in IBM that requires him to do research about humans' values. The extensive research had made him aware of the approach he had been adopting to change people around him, manupulating them to do what he wanted, was wrong.

He realized that when people were manipulated then the result would be temporary, because they would not believe the values he shared with them. Instead he began to value people they way they were, and let them thrive according to their talents.

To change people to do better, we have to understand their point of view. The different ways of seeing the world can create conflicts. But the ability to communicate the way the other person will understand is the key of successful of communication.

The way we see the world is called our PARADIGM.
Sometimes it is not about right or wrong, but because we see from different point of views that we have disagreement.

The concept of paradigm shift is very intresting... This concept is going to explains the meaning of "stand in someone else's shoes".
When you know other people situation, this will change your feeling...
There are 3 examples that really interest me...
1. The combination of picture of an old and young women.

2. The story of a husband that lost the wife and cannot control his children at the park when they were running wildly and out of control.
3. The story of a lighthouse. When the captain of the ship encounter another ship's light, he send the codes to order the "other ship to get put of his way. He was so angry to receive the answer that "the other ship" did not want to give way.... he was a captain, and the other ship must give him a way.  Later he found out that the other ship's light cannot change direction because it was out it was a lighthouse.
If he did not want to yield because of his ego, he would have ruined his ship.

Other terms you find in this book:
P=Product                     (the golden egg)
PC=Product Capability (the goose)
P and P/C balance principle= you have to take care of the goose to get the golden egg. Take care both of them.


Seven habits that make us effective:
1. Be proactive
is to act, not waiting to be acted upon, is the ability to choose your response. Even when you are under a bad situation, you can choose to be happy. When you choose to be happy, you will try to find ways to make the situation better and ask questions how to make the situation better, what we can do now. Do your best inside your circle of power and authority.
Illustration about: Victor Frankl, Joseph that was sold by his brothers, working with annoying boss.
Even when your boss is annoying, your hard work will be noticed by him and he will appreciate you in his heart.

2. Begin with the end in mind.
Begin with the end (the final result that you want to achieve) and take measures needed to go there.
Covey describes: all things created twice, first in the imagination, second in the reality. You have to have goal and describe in details the things and processes needed to be there.

Sometimes you don't create the first creation, other people or society did it for you, but you can change it and make it personal.

Do not forget that to achieve your goal, you have to be in a good balance.
Do not sacrifice one aspect of life to pursue the other, because in the end you will regret your decision.

Every body has a center, something that is important to the person. There are 10 common center and one additional center.
Marriage partner
Family
Money
Work
Possession
Pleasure
Friend
Enemy
Self
Religion

Pursuing one center and sacrificing others can be devastating... Maintain a good balance. To be able to be in balance, here comes the last center that is CORRECT PRINCIPLE CENTER.

(Red: What are correct principles? We can learn about these in this link, https://www.jw.org/en/ in this site, we are taught to love our Creator and to love our neighbors...what is interesting about this site is that it is teaching you to be balanced in every thing you do)


3. First  things first
4. Win-win solution
5. First understand, then being understood.
6. Synergize
7. Sharpen the saw
