Hai guys, Dr. Poetoe is falling in love today...so today i wanna write a story about my love journey with Yuanita herawati.

She is Yuanita Herawati. I called her "Anita / Yuan". She studied in Gunadarma University at informatic engineering which as same as like me. She is beautiful,Clever and has Kind Attitude. She is my partner to finish one of requirement to graduate from campus, it's called scientific paper. She has skill in programming, she better than me if make an application because she is smarter than me.

She can develop an e-commerce website with wordpress and php. I met her for the first time when I walked in motorcyle parking. When I met her for the first time, she looks like a man because her hair still short and she always wear jeans. Now, she is my girlfriend and she looks like more beautiful,more feminim than I saw her for the first time. She is really care about me and always pay more attention to me.

FIFA VS PES

Teman - teman tercinta, bertemu kembali dengan Dr. Poetoe dengan berbagai postingan terbarunya. Kali ini, aku akan membahas tentang "Permainan yang sering aku mainkan". Permainan favorit aku yaitu FIFA 2012. Hobi saya bermain sepakbola, oleh karena itu saya menyukai game/permainan yang berkaitan dengan sepakbola contohnya FIFA 2012. Apa itu Game Fifa 2012? Apa kelebihan Game ini dengan game sepakbola yang lain? Spesifikasi komputer yang mendukung permainan Fifa 2012? Semua jawaban ini hanya akan kamu dapatkan di www.putuananta.blogspot.com

Apa itu Game Fifa 2012, Dr. Poetoe?

Game Fifa adalah game sepakbola yang terbaru serta memiliki tampilan visual 3D dengan grafis yang baik karena memiliki kesamaan fisik maupun gaya permainan dengan pemain aslinya. Game Fifa ini memiliki suatu controller yang berfungsi untuk memudahkan pengguna untuk memberi operan, menembakkan ke arah gawang dan memudahkan kita melewati lawan.

Apa kelebihan Game ini dengan game sepakbola yang lain, Dr. Poetoe?

Disini aku ambil game lain yaitu PES sebagai game perbandingan pada game FIFA :

- Untuk fisik pemainn,Game FIFA lebih menyerupai pemain aslinya dibandingkan PES.

- Untuk grafik, FIFA lebih bagus dan emosi wajah para pemainnya sangat menyerupai pemain aslinya

- Penonton di FIFA lebih kelihatan asli dan disesuaikan dengan suasana pertandingan.

- Dari gaya permainan dan skill pemain, PES lebih bagus dan menyerupai pemain aslinya dibandingkan dengan FIFA.

Spesifikasi komputer yang mendukung permainan Fifa 2012?

Spesifikasi komputer yang recommended dan dibutuhkan untuk game ini adalah sebagai berikut :

Windows XP SP3, Vista SP2, 7
Intel Core2 Duo 2.0GHz or equivalent processor
2GB RAM
8GB free hard disk space
DirectX 9.0c compatible video card. 512MB Pixel Shader 3.0 (NVIDIA GeForce 7900 or AMD/ATI Radeon HD2400 or better)
DirectX 9.0c compatible sound card
DirectX 9.0c or higher (included on Disc)

How to Turn On/Off Oracle Service in Windows 7

Halo friends,,Back with me again Dr. Poetoe. Today, i wanna share to you about service.msc in Oracle. Oracle is a database management system from Sun Oracle. What is Service.msc in Oracle? How to turn on/off Oracle in Windows 7? Calm down guys!,you can get the answers only on www.putuananta.blogspot.com.

What is Service in Oracle, Dr. Poetoe?

Service.msc is used to set the startup types for Oracle services and it can be used to turn on/off the Oracle system in your Operating System.

How to turn on/off Oracle in Windows 7?

1. Go to Start - Run - type "services.msc" without quotes.

2. Scroll down to find the services with their names started with "Oracle" or type "Oracle" to search it quickly and we'll see the Oracle services have started. You'll see that your Oracle status is "started", It means that your oracle service still in active condition.

3. Now, we'll turn off or inactive the Oracle services so The localhost:5560/isqlplus can't run in our browser. Put your cursor to oracleDBCconsole, OracleOraDB10g (isqlplus), OracleOraDB10g, OracleServiceDBCL and click "stop the service" to turn off the oracle like this picture.

4. You can see the impact if you have turning off your Oracle Services with type localhost:5560/isqlplus in your browser,then you enter your username & password and you'll get the notification " ERROR - ORA-12560: TNS:protocol adapter error ".

5. To solve this error is very easy! you only to start turn on back your Oracle service in services.msc by click "start" and you'll get your Oracle has worked successfully like normally. You can see the differences when the services in on or off by enter your username & password. If your browser interface as same as this picture below,congrats to you! your oracle can work normally.

NOTE : You can use this tutorial if your xampp can't running in your windows,,maybe the port of oracle get crash with port in xampp,so you have to stop the service in oracle first and then run your xampp,,:)

Metode Biseksi,Regula Falsi,Newton Raphson, Secant

Pada postingan ini, saya akan membahas tentang beberapa program yang menggunakan metode Biseksi (Bagi Dua), Regula falsi , Newton Raphson, dan Secant ke dalam suatu aplikasi matematika. Aplikasi yang dipakai untuk membuat program ini adalah SAGE dengan menggunakan bahasa pemrograman yaitu phyton. Apa saja program menggunakan metode tersebut? Jawabannya hanya akan kamu dapatkan di www.putuananta.blogspot.com

Software : SAGE

Kelompok 1

- Ahmad Riyanto (54409285)

- Amelia Belinda (51409093)

- Bobby Elvan (52409442)

- I Putu Ananta (52409540)

- Nadia Riantini (50409541)

Kelas : 3IA01

Universitas Gunadarma

Apa saja program menggunakan metode tersebut, Dr. Poetoe?

1. Metode Biseksi (Bagi Dua)

Metode bagi-dua adalah algoritma pencarian akar yang membagi dua selang, lalu memilih bagian selang yang berisi akar seharusnya berada untuk diproses lebih lanjut. Metode ini sangat sederhana dan tangguh, tapi juga sangat lambat.

Berikut programnya :

omega=1.5

z_0=1

def f(z): return abs(math.cos(omega*z))-z/z_0 #nilai absolut dari kosinus omega z kurang z/z_0

a=-2

b=1

err=0.00001

n=0

nmax=10000

# Menentukan variabel-variabel float

dos = float(2); err = float(err)

# Sebelum ke algoritma kita mengevaluasi apakah perubahan fungsi mendaftar di ujung

if (f(a)*f(b)<0)&(n

# Carilah titik tengah pertama

c=(a+b)/dos

print 'Akar=',c, ' Nilai=',f(c),' Iterasi=',n,' (default)',' Presisi=',err

while abs(f(c))>err: # kondisi mutlak bahwa f (root) lebih besar dari kesalahan (perhatikan nilai absolut)

if f(c)*f(a)<0: # kondisi ini mengembalikan berbagai baru dengan perubahan tanda

b=c

else:

a=c

n=n+1 # iterasi memiliki

c=(a+b)/dos

print 'Akar=',c, ' Nilai=',f(c),' Iterasi=',n

else:

print 'f(a)=',f(a),' f(b)=',f(b),' Iterasi=',n

Output :

Akar= -0.5   Nilai= 1.23168886887   Iterasi= 0    (default)       
Presisi= 1e-05

Akar= 0.60990524292 Nilai= -2.02227274149e-06 Iterasi= 17

2. Metode Regula Falsi

Metode regula falsi adalah algoritma pencarian akar yang menggabungkan ciri-ciri dari metode bagi-dua dan metode sekan.

Berikut Programnya :

def sign(x): # determines the sign of its argument

if x == abs(x) : return 1 # argument was positive or zero

else: return -1 # argument was negative

# Solve f = 0 on interval [x1,x2] by interpolation, with tolerances

def interpol_solve(f,x1,x2,ftol,xtol):

f1 = f(x1)

if abs(f1) <= ftol : return x1

s1 = sign(f1)

f2 = f(x2)

if abs(f2) <= ftol : return x2

s2 = sign(f2)

if s1 == s2 :

sys.stderr.write("Same sign at %g to %g - exit!\n" % (x1,x2))

sys.exit(1)

while abs(x2 - x1) > xtol :

x3 = x2 - f2*(x2 - x1)/(f2 - f1)

f3 = f(x3)

if abs(f3) <= ftol : break

s3 = sign(f3)

if s3 == s1 :

(x1,f1) = (x3,f3) # replace pair (x1,f1) by (x3,f3)

else :

(x2,f2) = (x3,f3) # replace pair (x2,f2) by (x3,f3)

return x3

def quad(x): # a simple test function with known zeroes

return (x - 5.0)*(x - 2.0)

# a simple main to test the regula falsi solver */

root = interpol_solve(quad,1.0,3.0,0.000001,0.000001);

print root

3. Metode Newton Raphson

Metode Newton Raphson biasa digunakan dalam mencari akar dari suatu persamaan non linier, jika diasumsikan f mempunyai turunan kontinu f’.

Berikut programnya:

# newton's method

PRECISION = 10e-5

# x1 = x - f(x)/f'(x)

def newthon_method(x0,fn,fn_d):

while True:

x1 = x0 - ((fn(x0))/(fn_d(x0)))

if abs(x1 - x0) <= PRECISION: return x1

x0 = x1

print x0

# calculate the square sqrt of a number

# f(x) = X^2 - Number

# f'(x) = 2X

def newton_sqrt(num):

x0 = num/2

return newthon_method(x0,lambda x: x**2-num,lambda x: 2*x)

newton_sqrt(3214.0)

Output:

804.5
404.247513984
206.099044271
110.846744125
69.9208659915
57.9435579501
56.7056644466
56.6921527424
56.692151132233484

4. Metode Secant

Metoda secant merupakan salah satu metoda yang digunakan untuk mencari nilai akar dari persamaan y=f(x)



PRECISION = 0.00001

# x2 = x1 - ((x1-x0)/(fn(x1)-fn(x0)))*fn(x1)

def secant_method(x0,x1,fn):

 while True:

  x2 = x1 - ((x1-x0)/(fn(x1)-fn(x0)))*fn(x1)

  if abs(x2 - x1) <= PRECISION: return x2

  x0 = x1

  x1 = x2

  print x2

# calculate the square sqrt of a number

# f(x) = X^2 - Number

def secant_sqrt(num):

 return secant_method(num/2,num/4,lambda x: x**2-num)

secant_sqrt(3214.0)


Output:


537.0
324.277135397
205.916091836
132.004478363
89.9496774389
67.9769216068
59.0685940696
56.9032377885
56.6964766256
56.6921591697
56.692151132540069
