For price pixing BBM is influenced by four matters.

First, price of world oil, second relate to rupiah exchange rate, third hung from subsidy quantity that was established and fourth is calculation must be done bases mean value every year. Principally government never takes profit from price of oil fuel subsidized.
Whereas according to State's Minister of Development planning Nasional easter Suzetta, early next year possibility government cut under BBM. Until now government and some ministers relate and DPR still discuss degradation BBM.

According to Sigmund Freud (1856-1939), a psychology master Germany that considered as exponent psikoanalis, meyebutkan that personality (soul) formed by three strengths, that is id (ech), super ego (pursue ich) and ego (ich).

Id is passion or desire that berisis primitive motivations that have not yet influenced by culture or result learn, like motivation seks, aggresive, anger and that have the character of traumatik. This Id under nature realizes, until its apparition difficult controlled.

Google PageRank

Education Only

Education, Google PageRank, Information, Technology

adalah salah satu Elemen Penting yang menentukan peringkat sebuat halaman website di search engine (Google).Semakin tinggi PR maka semakin atas sebuah halaman tersebut ditampilkan di Search Engine khusunya Google.

PR adalah algoritma analisis link milik google yang memberikan bobot atau skor pada setiap elemen dari kumpulan dokumen di WWW yang memiliki hyperlink (Link masuk atau keluar). Nilai PR tersebut menetukan derajat kepentingan atau relevansi sebuah halaman web dalam hubungannya dengan halaman web lainnya PR menginterpretasikan sebuah link dari halaman 1 kehalaman 2 atau berikutnya sebagai Vote dari halaman pertama untuk halama berikutnya.

Google tidak hanya menghitung jumlah vote yang didapatkan oleh sebuah halama web, ia juga menganalisis halaman yang memberikan vote. Vote yang diberikan oleh halaman-halaman web yang juga "penting" akan memiliki bobot yang lebih tinggi, dan membantu halaman web yang menerimanya menjadi ikut "penting". dengan asumsi lain, vote yang diberikan oleh halaman web yang tidak penting tidak akan membantu dalam menaikan peringkat PR halaman yang menerimanya.

Nilai PR dari sebuah halaman web didefinisikan secara berulang (rekrusif), bergantung pada jumlah, dan bobot seluruh halaman web yang merujuk padanya (inbound link). Sebuah halaman web yang mendapatkan link masuk dari halaman web lainnya dengan nilai PR yang tinggi akan turut mendapatkan Score yang tinggi. Bila sebuah halaman web tidak link masuk, maka tidak ada suara atau dukungan untuk halaman web tersebut.

Google memberikan bobot 0-10 untuk setiap halaman web yang ada dii WWW;peringkat PR ini menunjukkkan seberapa penting halaman web ini di Google itu sendiri. sebuah halaman web yang mempunyai nilai PR 7 akan diurutkan lebih dahulu dalam daftar hasil pencarian Google daripada halaman web dengan nilai PR 6, dan seterusnya yang lebih kecil. PR sendiri merupakan turunan dari teori Probabilitas nilai dalam sebuah skala logaritma seperti skala Richter.

Algoritma PR

PR merupakan sebuah distribusi probabilitas yang digunakan untuk merepresentasikan kesamaan bahwa seseorang secara acak menklik link untuk sampai pada halaman web tertentu. Probabilitas diekspresikan sebagai nilai numerik antara 0 dan 1 , Probabilitas 0,5 secara umum diekspresikan sebagai "peluang 50%" bagi sesuatu untuk terjadi. Oleh sebab itu, PR 0,5 berarti terdapat peluang 50% bahwa seseorang mengklik pada link acak, yag akan diantarkan pada halaman web dengan nilai PR 0,5

Random Surfer Modul

RSM merupakan pendekatan yang menggambarkan bagaimana peluang seorang mengklik sebuah link berbanding dengan jumlah link yang ada pada halaman tersebut. Pendekatan ini yang digunakan Google, sehingga PR dari inbound link tidak langsung didistribusikan ke halaman web yang dituju, melainkan dibagi dengan jumlah outbound link yang ada pada halaman web tersebut.

Metode ini juga memiliki pendekatan bahwa seseorang tidak akan mengklik semua link yang ada pada semua halaman web. Oleh karena itu, PR menggunakan Damping Factor untuk mereduksi nilai PR yang didistribusikan sebuah halaman web ke halaman web lainnya. kemungkinan semua link yang ada pada sebuah halaman ditentukan oleh nilai damping factor (d) yang bernilai 0 sampai 1.

Nilai damping factor yang tinggi, berarti seseorang akan lebih banyak mengkilik sebuah halaman sampai dia berpindah ke halaman lain. setelah seseorang berpindah ke halaman web, maka Probabilitas diimplementasikan ke dalam algoritma PR sebagai konstanta (1-d). Dengan mengeluarkan variabel inbuond link, maka kemungkinan seseorang untuk berpindah ke halaman lain adalah (1-d). Hal ini akan membuat PR selalu berada pada nilai minimum.

Transformasi Base64 dalam Kriptografi

Education Only

Coding, Computer, Education, Information, OpenSource, Programming, Source Code, Technology

Transformasi Base64 adalah salah satu algoritma untuk encoding dan decoding suatu data kedalam format ASCI, yang di dasarkan pada bilangan 64. karakter yang dihasilkan dari Base64 teridiri dari A-Z , a-z dan 0..9, serta ditambah dengan 2 karakter terakhir yang bersimbol. Karakter simbol ini tergantung dari Algoritma yang digunakan.

Dalam materi Kriptografi Transformasi Base64 banyak digunakan di dunia internet sebagai media data format utnutk mengirimkan data, ini dikarenakan hasil dari Base64 berupa Palintext, maka data ini akan jauh lebih mudah dikirim, dibandingkan dengan format data yang berupa bineri.

Dalam Impleentasinya saya akan coba memberikan beberapa contoh dalam Transformasi Base64, yang antara lain adalah PEM, MIME, UTF-7, dan OpenPGP.

-PEM (Privacy-Enhaced Mail) adalah protokol pertama dengan teknik Base64 yang didasarkan pada RFC 989, yang terdiri dari 7 karakter (7-bit) yang digunakan pada SMTP dalam transfer data tapi untuk sekarang PEM sudah tidak menggunakan RFC 989 tapi sudah di ganti dengan RFC 1421 yang menggukana karakter A_Z, a-z, 0..9.

-MIME (Multi Purpose Mail Extension) didasarkan pada RFC 2045. Teknik encoding Base64 MIME, mempunyai konsep yang berdasarkan RFC 1421 versi PEM. Sedangkan MIME diakhiri dengan Padding “=” pada hasil akhir encodingnya.

-UTF-7 didasarkan pada RFC 2152, yang umumnya disebut “MODIFICATION BASE” UTF-7 menggunakan karakter MIME, tidak memakai padding”=”, karakter “=” digunakan sebagia escape untuk encoding.

-OpenPGP (PGP Prety Good Privacy) dirancang pada RFC 2440, yang menggukan Coding 64 Radix atau ASCI Amor. Teknik encodingnya didasarakan pada MIME tetapi ditambah dengan 24 bit CRC Cheksum. Nilai Cheksum dihitung dari data Input sebelum dilakukan Proses Encoding.

Contoh Transformasi Base64 dari plaintext “Hanjian” adalah “SGFuamlhbg==”. Untuk melakukan konversi kemabli dilakukan dengan cara yang sama untuk mendapatkan decoding nya seperti proses Konversi semula.

Implementasi Base64 pada Pemograman ASSEMBLY, transformasi BASE64 juga bisa dilakukan.

Ini adalah beberapa Code untuk Transformasi Base64

Operator Logika pada pemograman JAVA

operator boolean pada JAVA digunakan untuk melakukan operasi terhadap dua operand yang bertipe boolean. Hasil yang diberikan oleh operasi ini juga akan bertipe boolean. bebrapa operator pada boolean.

&& = Operasi ANS
|| = Operasi OR
^ = Operasi XOR (Exclusive OR)
! = Operasi NOT (Negasi)

Keterangan : T = True dan F = False

apabila 2 operand bernilai boolean (Contoh A dan B) dan keduanya digunakan dalam operasi AND, OR, XOR, dan NOT maka nilai yang dihasilkan antara lain, operasi AND hanya akan menghasilkan nilai true apabila kedua operand (A dan B) bernilai true; operasi OR hanya akan menghasilkan nilai false apabila kedua nilai operand false; operasi XOR hanya akan menghasilkan nilai true apabila salah satu operand-nya (bukan kedua-duanya) bernilai true; sedangkan operasi NOT akan menghasilkan negasi atau kebalikan dari nilai sebelumnya.

Contoh kode Program yang akan dihasilkan dari tabel diatas,

====================Mulai=============================

//PROGRAM Operator Logika dalam JAVA
class DemoOperatorLogika {
public static void main(String[] args) {

System.out.println("Operasi AND");
System.out.println("true && true = " + (true && true));
System.out.println("true && false = " + (true && false));
System.out.println("false && true = " + (false && true));
System.out.println("false && false = " + (false && false));

System.out.println("\nOperasi OR");
System.out.println("true || true = " + (true || true));
System.out.println("true || false = " + (true || false));
System.out.println("false || true = " + (false || true));
System.out.println("false || false = " + (false || false));

System.out.println("\nOperasi XOR");
System.out.println("true ^ true = " + (true ^ true));
System.out.println("true ^ false = " + (true ^ false));
System.out.println("false ^ true = " + (false ^ true));
System.out.println("false ^ false = " + (false ^ false));

System.out.println("\nOperasi NOT");
System.out.println("!true = " + (!true));
System.out.println("!false = " + (!false));
}
}
===================Selesai===========================

Hasil yang akan di berikan oleh program tersebut sebagi berikut:

Operasi AND
true $ true = true
true $ false = false
false $ true = false
false $ false = false

Operasi OR
true || true = true
true || false = true
false || true = true
false || false = false

Operasi XOR
true ^ true = false
true ^ false = true
false ^ true = true
false ^ false = false

Operasi NOT
!true = false
!false = true

Mudah-mudahan bermanfaat

Coding, Computer, Education, Information, OpenSource, Programming, Source Code, Technology

Lingkup Variabel dalam Pemograman Java

variabel yang dideklarasikan di dalam ruang lingkup (scope) atau blok tertentu hanya akan dikenali di dalam lingkup bersangkutan saja. Dalam Pemograman Java, blok diawali dengan tanda { dan di akhiri dengan tanda }.Dalam bahasa pascal, tanda tersebut dengan kata kunci begin dan end.

Coba perhatikan baris kode berikut.

===============Mulai=================
//PROGRAM Variabel Scope dalam JAVA
class LingkupVariabel {
public static void main(String[] args) {

int a = 10;

if (a > 5) { // awal blok
int b = 15;
System.out.println("Nilai a di dalam blok if: " + a);
System.out.println("Nilai b di dalam blok if: " + b);
} // akhir blok

System.out.println("Nilai a di luar blok if: " + a);
// SALAH
//System.out.println("Nilai b di luar blok if: " + b);
}
}
==============Selesai================

Nilai a di dalam blok if: 10
Nilai b di dalam blok if: 15
Nilai a di luar blok if: 10

COntoh di atas, Variabel b di deklarasikan di dalam blok if sehingga tidak akan dikenali lagi dari luar blok bersangkutan.
