Gurita

Hewan laut ini memiliki delapan tangan yang berguna untuk menangkap mangsa . Tangan - tangan yang fleksibel ini akan meraih mangsa , menggulung , lalu memakannya .

Tubuh gurita sangat lunak . Hal ini memungkinkannya untuk masuk ke dalam celah bebatuan yang sempit , baik untuk bersembunyi dari predator , maupun memburu mangsa.

Gurita memiliki mulut yang menyerupai paruh burung nuri ( mulut ini juga dimiliki oleh Cumi - Cumi ) . Paruh ini sangat bermanfaat ketika gurita menemukan mangsa berkulit keras , seperti kepiting.

Untuk menghindari predator , gurita melakukan kamuflase dengan mengubah warna kulitnya serupa dengan lingkungan disekitarnya . Kemampuan untuk mengubah warna ini juga dilakukan untuk memberi peringatan kepada gurita lain , misalnya untuk memberi tahu bahwa Gurita beracun yang berbahaya.

Penguin adalah burung yang paling khas di antara burung air. Meski tidaj dapat terbang , susunan tulang penguin sama dengan burung (aves).

Burung dari keluarga Sphenischidae ini memiliki 17 spesies . Penguin hidup dengan memakan hewan - hewan kecil yang ada di air , seperti Ikan , Cumi - cumi , atau Udang.

Penguin banyak ditemui di daerah Kutub Selatan yang beriklim dingin . Namun , sejumlah spesies ada yang hidup di daerah tropis dan subtropis, seperti di Kepulauan Galapagos.

Penguin pun memiliki masa pergantian bulu , dimana bulu - bulu lamanya akan rontok dan digantikan dengan bulu - bulu yang baru. Rontoknya bulu - bulu ini memakan waktu sebulan atau pun lebih . Semasa perontokan bulu tersebut, penguin sulit untuk mencari makanan dikarenakan bobot tubuhnya akan berkurang hingga 40 % .

Fakta menarik , bahwa penguin mempunyai kebiasaan yang mirip dengan AYAM , yakni menelan batu pada tembolok . Selain untuk membantu pencernaan , batu tersebut juga sebagai pemberat ketika penguin berenang.

Penguin masuk dalam rantai makanan sebagai Produsen II , dimana Penguin memakan Ikan , dan Penguin dimakan oleh Hiu ( predator penguin ).

Netbeans untuk memanipulasi MySQL

Netbeans adalah salah satu IDE Java yang sangat komplit khususnya fasilitas yang disediakan untuk mengembangkan aplikasi berbasis Java. Pada tulisan ini saya ingin menunjukan bagaimana kita menggunakan Netbeans untuk memanipulasi database. Database yang digunakan adalah MySQL.

Pra-syarat:

Netbeans IDE (dalam tulisan ini saya menggunakan versi 5.5.1)
MySQL server (dalam tulisan ini saya menggunakan veris 5.0)

Langkah Pengerjaan :

Buatlah database dalam MySQL misalnya dengan nama dbtest. Untuk tabel kita akan buat menggunakan Netbeans.

Jalankan Netbeans, pilih tab Runtime

\

Selanjutnya kita akan menciptakan koneksi ke database kita. Untuk itu kita butuh MySQL konektor. Pada tulisan ini saya menggunakan versi 5.0. Silahkan download disini

Ekstraklah MySQL Konektor yang telah didownload

Selajutnya kita daftarkan Konektor tersebut ke Netbeans

Pada tampilan seperti gambar di atas klik kanan pada Driver, pilih New Driver.

Pada window New JDBC Driver, pilih tombol Add

Carilah Konektor MySQL dilokasi yang sesuai

Kemudian OK

Maka , Konekor MySQL sudah terdaftar ke Netbeans

Untuk menciptakan koneksi ke database kita (dbtest), klik kanan pada MySQL Connector seperti pada gambar di atas, dan pilih Connect Using…

Pada Window Database Connection, masukan database url, user dan password. Data ini tentunya menyesuaikan dengan Server MySQL Anda.

Kemudian pilih OK 2x

Kalau koneksi ke MySQL berhasil maka akan ditampilkan tampilan seperti berikut ini

Selanjutnya kita akan membuat table untuk database kita.

Klik kanan pada folder Table dan pilih Create Table

Pada Window Create Table isilah nama table dan field-field yang diinginkan

Untuk menambah field atau kolom klik pada tombol Add Column

Selanjutnya pilih OK untuk mengakhiri pembuatan table

Jika berhasil akan ditampilkan tampilan seperti gambar berikut

Sampai disini kita telah dapat menambahkan table ke dalam database kita menggunakan Netbeans IDE. Selanjutnya untuk memanipulasi data dalam table tperson yang baru dibuat, kita dapat menggunakan perintah-perintah SQL langsung dari Netbeans IDE juga.

Pada Table tPerson klik kanan dan pilih Execute Command…

Maka pada bagian kanan dari Netbeans IDE akan ditampilkan editor tempat kita menuliskan perintah SQL kita.

Untuk mengeksekusi perintah SQL yang sudah kita tulis, silahkan klik pada icon Run SQL seperti pada gambar di atas.

Jika SQL kita berhasil dieksekusi maka pada status bar Netbeans akan terdapat pesan bahwa SQL berhasil dieksekusi.

Untuk menampilkan data yang sudah ada pada table tPerson kita dapat juga menuliskan perintah SQL pada SQL Editornya misalnya SELECT * FROM tperson, maka akan ditampilkan seluruh data yang ada pada table tPerson pada bagian bawah dari SQL Editornya.

Hal yang sama juga dapat kita lakukan untuk operasi Update atau Delete.-

Demikian Materi kali ini yaitu , Net Beans untuk memanipulasi mySQL , semoga berguna bagi para pembaca.

10 Tips meningkatkan Traffic Pengunjung

Dalam setiap kehidupan blogger terdapat hari istimewa yaitu hari mereka pertama kali meluncurkan blog baru. Anda tentunya berharap mendapatkan pembaca setia blog anda atau mungkin beberapa hari kemudian Anda menerima beberapa pengunjung ketika Anda memberitahu adik Anda, ayah, pacar dan sahabat Anda tentang blog baru tapi tentunya anda mengharapkan banyak pembaca yang akan membaca tulisan anda di Blog. Berikut ini adalah 10 teknik baru blogger dapat digunakan untuk menemukan pembaca.

Ini adalah tips khusus untuk blogger baru, orang-orang yang ingin mendapatkan pengunjung banyak dan membuat blognya menjadi terkenal.

Teknik ini akan membantu anda dan , jika anda mengikuti daftar ini dari atas ke bawah dan menerapkan teknik masing-masing maka Anda telah menciptakan momentum. Akhirnya setelah Anda membangun momentum yang cukup Anda mendapatkan apa yang disebut "traksi", yang merupakan basis penonton cukup besar (sekitar 500 pembaca hari adalah baik) bahwa Anda tidak lagi harus bekerja terlalu keras untuk menemukan pembaca baru. Sebaliknya saat ini Anda pembaca setia melakukan pekerjaan untuk Anda menyampaikan ke orang-orang.

10. Write at least five major "pillar" articles. A pillar article is usually a tutorial style article aimed to teach your audience something. Generally they are longer than 500 words and have lots of very practical tips or advice. This article you are currently reading could be considered a pillar article since it is very practical and a good "how-to" lesson. This style of article has long term appeal, stays current (it isn''t news or time dependent) and offers real value and insight. The more pillars you have on your blog the better.

9. Write one new blog post per day minimum. Not every post has to be a pillar, but you should work on getting those five pillars done at the same time as you keep your blog fresh with a daily news or short article style post. The important thing here is to demonstrate to first time visitors that your blog is updated all the time so they feel that if they come back tomorrow they will likely find something new. This causes them to bookmark your site or subscribe to your blog feed.

You don''t have to produce one post per day all the time but it is important you do when your blog is brand new. Once you get traction you still need to keep the fresh content coming but your loyal audience will be more forgiving if you slow down to a few per week instead. The first few months are critical so the more content you can produce at this time the better.

8. Use a proper domain name. If you are serious about blogging be serious about what you call your blog. In order for people to easily spread the word about your blog you need an easily rememberable domain name. People often talk about blogs they like when they are speaking to friends in the real world (that''s the offline world, you remember that place right?) so you need to make it easy for them to spread the word and pass on your URL. Try and get a .com if you can and focus on small easy to remember domains rather than worry about having the correct keywords (of course if you can get great keywords and easy to remember then you''ve done a good job!).

7. Start commenting on other blogs. Once you have your pillar articles and your daily fresh smaller articles your blog is ready to be exposed to the world. One of the best ways to find the right type of reader for your blog is to comment on other people''s blogs. You should aim to comment on blogs focused on a similar niche topic to yours since the readers there will be more likely to be interested in your blog.

Most blog commenting systems allow you to have your name/title linked to your blog when you leave a comment. This is how people find your blog. If you are a prolific commentor and always have something valuable to say then people will be interested to read more of your work and hence click through to visit your blog.

6. Trackback and link to other blogs in your blog posts. A trackback is sort of like a blog conversation. When you write a new article to your blog and it links or references another blogger''s article you can do a trackback to their entry. What this does is leave a truncated summary of your blog post on their blog entry - it''s sort of like your blog telling someone else''s blog that you wrote an article mentioning them. Trackbacks often appear like comments.

This is a good technique because like leaving comments a trackback leaves a link from another blog back to yours for readers to follow, but it also does something very important - it gets the attention of another blogger. The other blogger will come and read your post eager to see what you wrote about them. They may then become a loyal reader of yours or at least monitor you and if you are lucky some time down the road they may do a post linking to your blog bringing in more new readers.

5. Encourage comments on your own blog. One of the most powerful ways to convince someone to become a loyal reader is to show there are other loyal readers already following your work. If they see people commenting on your blog then they infer that your content must be good since you have readers so they should stick around and see what all the fuss is about. To encourage comments you can simply pose a question in a blog post. Be sure to always respond to comments as well so you can keep the conversation going.

4. Submit your latest pillar article to a blog carnival. A blog carnival is a post in a blog that summarizes a collection of articles from many different blogs on a specific topic. The idea is to collect some of the best content on a topic in a given week. Often many other blogs link back to a carnival host and as such the people that have articles featured in the carnival enjoy a spike in new readers.

To find the right blog carnival for your blog, do a search at http://blogcarnival.com/.

3. Submit your blog to blogtopsites.com. To be honest this tip is not going to bring in a flood of new readers but it''s so easy to do and only takes five minutes so it''s worth the effort. Go to Blog Top Sites, find the appropriate category for your blog and submit it. You have to copy and paste a couple of lines of code on to your blog so you can rank and then sit back and watch the traffic come in. You will probably only get 1-10 incoming readers per day with this technique but over time it can build up as you climb the rankings. It all helps!

2. Submit your articles to EzineArticles.com. This is another tip that doesn''t bring in hundreds of new visitors immediately (although it can if you keep doing it) but it''s worthwhile because you simply leverage what you already have - your pillar articles. Once a week or so take one of your pillar articles and submit it to Ezine Articles. Your article then becomes available to other people who can republish your article on their website or in their newsletter.

How you benefit is through what is called your "Resource Box". You create your own resource box which is like a signature file where you include one to two sentences and link back to your website (or blog in this case). Anyone who publishes your article has to include your resource box so you get incoming links. If someone with a large newsletter publishes your article you can get a lot of new readers at once.

1. Write more pillar articles. Everything you do above will help you to find blog readers however all of the techniques I''ve listed only work when you have strong pillars in place. Without them if you do everything above you may bring in readers but they won''t stay or bother to come back. Aim for one solid pillar article per week and by the end of the year you will have a database of over 50 fantastic feature articles that will work hard for you to bring in more and more readers.

Woman Trafficking Case in Indonesia

The most issue in Indonesia about the women’s lives about the women’s trafficking this issue not due to just women lives but this related with human rights, i dont know what and why this can be happen in Indonesia, and that i cant to accept this Indonesia got 3th grade in Women Trafficking.

I know this is the generally rumor, but i want to try look from other paradigm. As we know, the most factor that influence the womens trafficking is economical factor. But now i want to look from environment paradigm that where the women was live.

Maybe that not only economical factor, many people in Indonesia dont know about the trafficking, and many of people i ask “Do you know what is trafficking?” , many of people said “i dont know”. That the problem, this problem was very dangerous.

How we can avoid something but we dont know what is that. This question i ask to urban people live in the big city. But, how in the side of the city, how they will know, beside of that, people live in big city dont know that.

What about the people in the side of the city, have they know? The point is the socialization in the people environment.

Many factor can be affected by trafficking especially women trafficking, now we focus on environment. Women who lives in village dont know about human trafficking, but i know she is rich , her father is the leader of that village and her mother is a teacher. One day, some people come to her house and asking and recruiting to join working in other countries.

And then , she requested time to her parent. And they accept that and promise to back in 2 days. She is begging to his parent, but two of us accept that . That mean two of us had accepted the human trafficking? i answer NO, why? Two of us dont know what his daughter want. She say to them (his parent), to just work in other cities , and didnt asking his parent to go to outside country in the other words “She is lying”.

But she dont know she is one of trafficking victims, next days the people come again. And the people meet her parent and she is ready to going up with her bag and some of luggage. And she had given money up to 4 juta rupiah (equal $421) , and she is going with the people go to big city . And she is transfered with other trafficking victims to other country.

One years past, and she didnt give information to her parent in country. The parent just got information from the agent that agent said : “She is well”. But, the reality, she is sold. One day, the parent very worried about her condition. And they called the agent via phone. But now, they cant contact with the agent. So, they are worry about her safety. And they called the police, and the police said : “We will investigate this”.

Five years past, since they cant contact with the agent. They very worried, and trying to asking people where they can find her. And, one day they got information, she is die. Because she is jumping from fifth floor of the apartement. The reality is, she is going to outside country and working as sleve, after that she is married and have a conflict with his husband and she choice to die with suicide.

The story is the scene, why trafficking in Indonesia not only affected by economical side but, environment too. The fact is some of people want to try to going outside country but dont know that the victim of trafficking. And for example that ladies. She must to ending his life with suicide.

Other factor is the socialization we must sure that the information had distribute to the people who live in the side of city. Because many of trafficking agent that operation in Indonesia have a target the people who live in side of the city, especially the women and we can called her ‘mojang desa’. In that story, we know that her parent have a good job. But, how the daughter doing, she is victims of himself.

So , i have some suggest that i hope can reduce trafficking in Indonesia.

Socialization to side of the city about what the trafficking is it.
The law must be established especially , Human Trafficking law, and Human Rights Law.
Law enforcement must be proactive about human trafficking.
The minister of Indonesia in the other country must be sensitive about his people who working and staying in other countries.
Migration and passport registration must be more responsive to the people who suspect to be trafficking victims. Because as we know that cannot be go to outside country without that, but some of trafficking agent didnt use passport because of that the trafficking victim can be problem with that and have antoher law problem that is “Illegal Comer”.
Make sure not just socialization that government can doing, but action to caught all of the trafficking agent.

I think just this i can to say about my essay, and i hope all of the judge who choice the best essay will doing the best and hope the best is the winner. I just want to say thank you to CEDAW who doint this program. I hope this essay event can motivate young people the way to care about the issue in his country.

Say no to Trafficking and Save our Woman…
