Why should we learn MATHEMATICS ?

As we know, it’s a must for every student to learn mathematics. Some students think that mathematics is so easy and fun. But, some of them think that math is really difficult and useless.. And I had been one of them. Before I thought, why should I learn math? It’s only about confusing number and formulas. Moreover when I had to study trigonometry and logarithmic that are difficult for me.

So, I searched about the purpose of studying this lesson. Then, finally today I got the answer! Alhamdulillah.. it made me become more convenient and enthusiastic to study math. It was when I was joining ‘Kuliah Dhuha’ about Science at Masjid Jami’ Malang this morning. The Ustadz said that when we study anything, it should make our faith of Allah SWT increase and also aware about the greatness of Allah.


"Ilmu yang bermanfaat adalah ilmu yang masuk (dan menetap) ke dalam relung hati (manusia), yang kemudian melahirkan rasa tenang, takut, tunduk, merendahkan dan mengakui kelemahan diri di hadapan Allah Subhanahu wa Ta'ala. " - Ibnu Rajab al-Hambali

So, I asked about what the relation between math, knowledge and faith is. Here is the answer :

11.   Mathematics is the foundation of almost all science

Why? It is because to be able to learn every lesson we need math. When we study physics or chemistry, absolutely we need math to calculate the formula, etc. When we study biology, we need math to solve the probability of heredity problems. Even Islamic lesson needs math ability, to calculate the amount of zakat, etc.

22. Mathematics contains many lessons about the greatness of Allah SWT

For example, you know prime numbers(bilangan prima) right? Prime number is a natural number greater than 1 that is only can be divided by 1 and itself. Like 2,3,5,7, and so on. Friends, actually, it also give us an important lesson. That’s even somebody is only by her/himself (alone), actually there is 1 God who always beside him. That’s why every bank wants to give its ‘pelayanan prima’, because when the servicers aware that they’re not alone, they will give their best service to the public.

There are still many reasons of why we should learn math is. So friends, let’s study MATH!! :D

Thank you^^

COPY PASTE

Oh, I don’t know when this culture is started. It seems that ‘Copy Paste’ culture is belong to most of Indonesian people. From technology, music, style, and especially copy paste culture in the school. The worst copy paste action that I had seen these days made me always think about this problem. The students are copying their friends’ answer without feeling afraid. Even though they already knew that there is a teacher watching them, and of course God that always watching them.. They tip their cell phone below the table to get 1-50 answers from SMS. So, I think it is the reason why we as Indonesian people can’t develop our self well and effectively. It is because we’re always cheating. To be successful what we need is honesty. Why? First, because by being honest, we can know about our real ability. So, we can know our good side and bad side. We can use our good side, and fix our bad side. If we always do cheating, and we get good scores we wouldn’t know what subject is the best for us. It makes we as the 12^th grade student are confuse to choose the subject that we will learn at the university. The second reason, what is the use of good scores actually, if we don’t get any knowledge. Is our purpose to study at school only to get those numbers and rank? No, the purpose of studying is to get as many knowledge as we can. The knowledge that will make we are different and better than the one who doesn’t study.  The third reason, please ask to yourself. Which one the score that will make you happier, your real score or copy paste result? Of course our real score that will make we are happier, because it comes from our hard work. So friends, let’s try to be honest, than you’ll see that you can do everything independently. You are SMART! You are GREAT!

I Love Physics

Aku memang selalu suka pelajaran fisika. Berfikir menggunakan logika, dan menemukan kejadian - kejadian menarik di sekitar kita yang bermanfaat dalam penemuan teknologi. Selain itu, fisika juga bisa membuat hal - hal yang tidak masuk akal menjadi masuk akal secara ilmiah. Seperti dalam teori relativitas yang aku pelajari siang ini di sekolah. Aku baru tau bahwa kita bisa lebih awet muda saat kita bergerak dengan kecepatan yang sangat cepat hingga mendekati kecepatan cahaya. Seperti saat kita menjadi astronaut yang bergerak di luar angkasa, maka waktu yang kita rasakan akan berbeda dengan waktu yang orang di bumi rasakan. Di bumi waktu berjalan begitu cepat!

Aku juga baru tau bahwa informasi di dunia ini tidak pernah bisa hilang. Suara kita dan apapun yang kita lakukan. Karena energi itu tidak bisa lenyap, hanya bisa berubah bentuk. Maka dari itu kata guruku, ada orang yang bisa melihat kejadian di masa lalu dengan hanya melihat tempat kejadian. Sebenarnya kita juga bisa, tetapi kita kurang peka dan sensitif untuk membedakan kejadian dan hal - hal yang tumpang tindih. Seperti pada suatu hari, ada orang yang kehilangan separuh tangannya saat kecelakaan. Lalu saat ia bangun dan badannya di foto aura, maka pada foto aura itu tangannya masih terlihat, walaupun sesungguhnya tangannya sudah tidak ada. Hal itu karena orang tersebut dalam pikirannya masih menganggap bahwa dia memiliki tangan. Wow! Science is amazing.. Subhanallah :)

SISTEM JARINGAN KOMPUTER

Jaringan Komputer adalah sekelompok hardware seperti PC, Printer dan peralatan lain yang saling terhubung dan terjadi interaksi komunikasi.
Dilihat dari segi konfigurasi jaringannya, jaringan komputer memiliki 2 macam konfigurasi yaitu Peer to Peer dan Client-Server. Konfigurasi Peer to Peer biasanya melibatkan kurang dari 10 komputer, setiap komputer bisa saling berbagi data tanpa mengutamakan keamanan. Kelebihan dari konfigurasi Peer to Peer adalah pembangunan sistem jaringan yang mudah dan tidak memerlukan server. Namun, kekurangannya adalah kurang fleksibel dan kurang aman. Konfigurasi Client Server memiliki satu komputer sebagai server atau pusat kendali. Server mengendalikan akses komputer - komputer lain yang disebut client. Kelebihannya adalah dapat melibatkan peralatan yang tidak terbatas jumlahnya, dan tingkat keamanannya tinggi. Sedangkan kekurangannya adalah pembangunan sistem lebih sulit dan membutuhkan tenaga ahli khusus server.
Dilihat dari segi letaknya, jaringan komputer dibagi 3 yaitu LAN, MAN, & WAN. LAN( Local Area Network) merupakan suatu sistem yang menghubungkan komputer dalam jaringan yang tidak luas yaitu 10 m s/d 1 km. Sedangkan kecepatan transmisinya sebesar 10 s/d 100 Mbps. MAN( Metropolitan Area Network) adalah sistem jaringan yang memiliki radius pelayananannya terbatas pada sebuah kota atau provinsi dengan jarak 10 km s/d 100 km. Umumnya MAN menggunakan medium gelombang elektromagnetik (wireless). WAN ( Wide Area Network) adalah sistem jaringan yang menghubungkan jaringan antar negara / benua. Biasanya menggunakan media kabel bawah laut atau satelit dengan jarak lebih dari 100 km dan kecepatan transmisi 64 kbps.
Dlihat dari segi media transmisinya, terdapat 2 jenis yaitu jenis jaringan kabel dan nirkabel (wireless). WLAN (Wireless Local Area Network) hampir sama dengan LAN, namun apabila LAN menggunakan kabel WLAN menggunakan media gelombang elektromagnetik.Keunggulan wireless ada lima yaitu mobilitas, kecepatan instalasi, fleksibilitas tempat, pengurangan anggaran biaya dan jangkauan yang luas. Sedangkan kelemahannya adalah alat yang mahal, dapat terjadi interferensi gelombang, kapasitas jaringan terbatas, keamanan data kurang terjamin dan sinyal putus - putus (intermittence).
Internet merupakan sebuah sistem jaringan global yaitu jaringan seluruh dunia yang melibatkan berbagai infrastruktur jaringan. Intranet adalah miniatur jaringan internet yang terbatas pada lingkungan lokal saja, contohnya sebuah gedung. Ekstranet memiliki jaringan yang lebih luas daripada intranet. Biasanya diterapkan untuk perusahaan - perusahaan yang memiliki cabang di tempat yang berbeda.

Eagle is Endangered

The Javan Hawk-Eagle is the national bird of Indonesia. In Indonesia, it is usually known as Garuda. This bird has become the national emblem of Indonesia that symbolizes strength and power. Nevertheless, it’s so difficult for us to see eagles in Indonesia because there were only around 400 Javan Hawk-Eagles living in the wild. This number is continually decreasing, making eagle an endangered species. There are several factors endangered Javan Hawk-Eagles:

1.      1. The declining of habitat quality

The Javan Hawk-Eagle occurs in humid tropical forests of Java. Its range in East Java includes Sempu Island, Bromo Tengger Semeru National Park, Meru Betiri National Park, and Alas Purwo National Park. There are also some eagles 

that live in Gunung Halimun Salak National Park. But according to the officer of the national park, there has been damaged to the protected forest. It made the eagles loss their habitat and food. The damaged of protected forest is caused by human activity like illegal logging.

1.     2.   The slow growth and breeding of eagles

The Javan Hawk-eagle is mature at the age of three or four. It is believed to be monogamous. It means that this bird is so loyal to its pair. It breeds once every one or two years. The slow growth triggers the low survivability of the bird. Although eagle is an Indonesian endemic, but Indonesia still can’t breed this rare raptor because the habitat is still damaged.

2.   3.     Illegal hunting

The Javan Hawk-Eagle is one of the most beautiful and exotic bird in the world. It has dark brown body. Its head and neck are rufous and it is heavily barred black below. Its long black crest with a white tip makes this bird be more unique. People are still hunting this bird to be sold or to be keep in a cage because of its beauty. 

From the factors above, we can conclude that human activity is the most affecting factor of the decreasing of the eagles’ number in Indonesia. The preservation of rare animals is the responsibility of all parties. Moreover, it is our national bird ‘Garuda’ that is becoming endangered. Do not let Indonesian children can’t see eagles in the future. The things that we should do to preserve eagles and other rare animals are :

1.     a.Do not destroy forests and other natural environment such as sea, lake, etc.

2.     b.Do not hunt wild and rare animals.

3.     c.Do not buy or sell rare animals.

4.     d.Comply the government regulations on protecting endangered animals.

 

There are some government regulations to protect endangered animals. Some of them are :

1.   1. UU No. 5 1990, about the conservation of natural resources and ecosystems.

2.   2. Kepres No. 4 1993, about National Flora & Fauna that set eagle as the wildlife national pride.

1st day of My holiday in Jakarta

I was sitting at a terrace inside Mbak Ai and Mas Oryz's house when i wrote this first post. Although i' m in Jakarta the air is not hot and so calm. I also can't hear any noise from the traffic on the city way. Instead, here i can hear the voice of falling water from an aquarium and low voice of children playing behind the house..
The first day of my holiday in Jakarta was so wonderful. My family and I came to mbak Ai's house, i love the house because its design is so modern, simple but cool! The gate's color is green but the inside wall and the door is mixed by cream and white. After we get some rests, i did badminton exercise. I played badminton with mas Oryz and his neighbor Pak Irfan. In the night, i went to Mal Kelapa Gading. There are many big discounts, so my mom bought me a running shoes. Alhamdulillah, i really need it for physics. We also bought a thin pizza in Pizza Cafe, there is no pizza like that in Malang, ehmm.. so yummy! We came to an arabian, indian & egyptian food bazaar. There were many kinds of food and beverages. For example, satay, prata, and date fruit. We ate until full and went home. But when we arrived and went inside my room, my sister found a scorpion on the floor! thank God it had not bite us..
