MANFAAT TIDUR MENGHADAP KE KANAN (SUNAH RASULULLAH SAW)


Rasulullah SAW bersabda:
"Jika kamu bergegas menuju tempat tidurmu, berwudhulah seperti wudhu untuk shalat kemudian berbaringlah miring ke kanan seraya mengucapkan, 'Ya Allah, aku serahkan diriku kepada-Mu. Aku limpahkan urusanku kepada-Mu. Aku minta perlindungan tubuhku kepada-Mu karena cinta dan rasa takutku kepada-Mu, tidak ada tempat kembali dan tidak pula keselamatan dari kemurkaan-Mu kecuali kepada-Mu. Aku beriman kepada kitab-Mu yang telah Engkau turunkan dan kepada nabi-Mu yang telah Engkau utus.' Jika kamu mati pada malam tersebut, kamu mati dalam keadaan suci. Karena itu, jadikanlah doa tersebut sebagai kalimat terakhir yang kamu ucapkan."
(Hr. Asy-Syaikhan)

Berikut ini adalah manfaat tidur menghadap ke kanan dari segi kesehatan: 
  1. Mengistirahatkan otak kiri. Pada dasarnya, otak manusia dibagi menjadi dua bagian yaitu otak kiri dan otak kanan. Otak kanan bertugas mempersarafi organ tubuh sebelah kiri, begitu juga sebaliknya. Dalam keseharian, kita sering menggunakan organ tubuh sebelah kanan. Dengan tidur miring ke kanan, maka gantian otak kiri yang mensarafi organ tubuh sebelah kanan. Dan ini dapat menghindarkan diri dari bahaya penyakit seperti pengendapan pembekuan darah, lemak, asam sisa oksida, dan penyempitan pembuluh darah.

HOW DO WE GET THE FORMULA OF ARITHMETIC MEAN?


The students have already known about the formula of arithmetic mean that they have known and used for years. To find the mean of two numbers, add then and then divide the sum by two.
But, Can you find out the way to get that formula?
Actually, it is a simple way to get the formula of arithmetic mean. But sometime, people do not really know about it.

Everyone has known about the arithmetic formula:

We then use the concept just presented to find the missing middle term, or arithmetic mean, if the first and third terms of an arithmetic sequence are given. To begin I use an example.
If we are given that a, n, b are three consecutive terms in an arithmetic sequence, how do we find the value of n?

WHAT IS FRACTION?

I am just trying to find out what is fraction. And I get new knowledge about fraction. This review about fraction I have gotten from other site.

Fractions

Fraction notation and operations may be the most abstract math monsters our students meet until they get to algebra. Before we can explain those frustrating fractions, we teachers need to go back to the basics for ourselves. First, let’s get rid of two common misconceptions:
  • A fraction is not two numbers.
    Every fraction is a single number. A fraction can be added to other numbers (or subtracted, multiplied, etc.), and it has to obey the Distributive Law and all the other standard rules for numbers. It takes two digits (plus a bar) to write a fraction, just as it takes two digits to write the number 18 — but, like 18, the fraction is a single number that names a certain amount of whatever we are counting or measuring.
  • A fraction is not something to do.
    A fraction is a number, not a recipe for action. The fraction 3/4 does not mean, “Cut your pizza into 4 pieces, and then keep 3 of them.” The fraction 3/4 simply names a certain amount of stuff, more than a half but not as much as a whole thing. When our students are learning fractions, we do cut up models to help them understand, but the fractions themselves are simply numbers.

DIVISION OF INTEGERS

Hari pertama mengajar sebagai guru PPL di SMP N 2 Smg, cukup rame kelasnya, ^_^
Aku mendapat kelas yang berisi anak-anak yang sangat aktif, sampai-sampai gurunya kewalahan. Tapi wajar sajalah, maklum masih kelas VII. :)
Planing program pembelajaran yang sudah ku buat kadang tidak bisa sesuai karena aku selalu merasa kekurangan jam, hehe. Semoga besok-besok bisa mengatur kelas lebih efektif dalam penggunaan waktunya.

Hari pertama aku mengajar adalah hari Selasa, 28 Agustus 2012. Materi hari itu adalah Division of Integers.
Pertama-tama, perkenalan dalam konstek wajar ^_^. Lalu membahas homework dari pertemuan sebelumnya. Kemudian, aku terangkan materi Division of Integers. Sebagai elaborasi, aku berikan latihan soal yang dikerjakan berkelompok. Tapi karena waktunya habis akhirnya dijadikan homework deh.... ^_0

Ini adalah materi tentang Division of Integers:

MATHEMATICS GAMES

Minal aidzin walfaidzin.. Mohon maaf lahir batin ya.... :)

Games??
Langsung inget Kyuhyun ^_^ (sorry lebay).
And because Iam a gamers , that doesn't mean that I like playing games (read: gamers is one of Kyuhyun's fan club). kekeke. Honestly, I don't like playing game, the evidence is on my laptop doesn't exist any game and on my handphone only two games but only one that I usually play it.

But now, I will discuss about mathematics games. Yes.. Children need a way to fall in love with mathematics and maybe it can happen through a mathematics game. Thanks to genius person that can create mathematics games but doesn't include me 0_o  ....

Okay, I will post some mathematics games that I get from goggling.

1. Game matematika untuk anak kelas 6 SD

Review:
Aplikasi game edukatif matematika ini terdiri dari 2 menu di mana menu tersebut terdiri darimateri mata pelajaran matematika yaitu KPK dan FPB lanjutan, luas dan keliling, koordinat kartesius, bangun ruang, dan menu game yang berupa permainan menjawab soal yang berhubungan dengan pelajaran dengan cara yang menarik.

This software is called Microsoft Math 2007.
It really useful for you to study about mathematics. For example, if you are confused how to graph a mathematics function, this software will help to get the graphic of a function.

You can download this math software here.

Happy mathematics. Thanks. Gomawo ^_^

SETS (Himpunan)

Sets is a material of Senior High School grade VII semester2. I had made this material some month ago, now I want to share it for everyone if you need to know about this material.
I convert it become pdf. I can't write it here directly because some of this writing consist of math equation.
Here, some previews:
______________________________________________
SETS
I.  UNDERSTANDING SETS
A set is a collection of objects which can be clearly defined.
Example:
-  A group of the color of traffic light.
-  A herd of reptile animals.
-  A group of humans who born in October.
Look at the following groups which are not considered as a set:
-  A group of handsome boys in my class 
-  A group of cheap cloths in the market.

II.  SYMBOL AND MEMBERSHIP OF A SET
A set is usually denoted by a  capital letter  such as A, B, C, …, Z. The objects 
which are included in a set may be expressed using brackets.
Example:
1.  A set of natural numbers which are less than 5.
K = {1,2,3,4} 
2.  A set of basic color.
G = {red, yellow, green}

Database Relasi Tabel (Table Relation) 'Car Dealer 2012'

Setelah rehat cukup lama dan meninggalkan blogger untuk sementara. Finally, Iam coming back ^_^
Dalam perkuliahanku di semester 6 ini, ada makul Database. Sempat aku dapat tugas untuk membuat relasi tabel. Dan setelah praktek berutik-utik selama berjam-jam, akhirnya sudah cukup paham mengenai relasi tabel.
Dan ini adalah hasil percobaanku saat membuat relasi tabel yang berjudul tentang 'Car Dealer' . . .
(entah ini sudah bener2 betul apa belum,, yang penting programnya bisa dijalankan dulu, lain kali pasti aku coba-coba bikin lagi kalau lagi ada waktu luang, maklum sekarang lagi demam LouHan, xpxpxpxp :p ) . . .
