10 Tips Lulus Ujian Nasional

Pada kesempatan kali ini, saya akan menyampaikan beberapa tips agar dapat sukses menjalankan dan meraih sukses dalam UN. Berhubung dengan semakin dekatnya para siswa kelas akhir di masing-masing jenjang akan melaksanakan satu uji kompetensi yang menentukan lulus atau tidaknya seorang siswa dari jenjang tersebut. Berikut ini adalah tipsnya :

1. Belajar Maksimal, Namun Tetap Rileks

Cara yang pertama ini adalah sebagai langkah memulai untuk memutar memori pelajaran yang telah tersimpan dalam syaraf otak. Sehingga belajar yang maksimal dan rileks menjadi pekerjaan rutin sebagian siswa yang akan menempuh ujian nasional. Bila perlu dengarkan secara rutin MP3 Hipnoterapi yang secara cuma-cuma alias gratis telah saya upload di SINI. Mungkin teman-teman butuh jutaan rupiah jika hipnoterapi,tapi ini saya bagika secara gratis.

2. Belajar Berkelompok Sebelum Menempuh Ujian

Tips ini sangat efektif jika dilakukan dengan sungguh-sungguh dan fokus. Karena salah satu langkah ini dapat membuat kita lebih mengetahui apa yang telah teman kita ketahui terlebih dahulu dalam bidang tertentu.

3. Membuat Referensi Pelajaran

Pelajaran yang lalu pasti ada saja yang kita lupakan. Resume atau rangkuman adalah salah satu cara untuk mengembalikan semua pelajaran yang kita agak lupa. Bahkan cara ini dapat kita lakukan dalam setiap pelajaran yang kita anggap menyulitkan kita.

4. Mempersiapkan Segala Yang Dibutuhkan Saat Ujian

Alat tulis menjadi hal utama dalam menjalankan ujian. Seperti pensil khusus, papan jalan serta penghapus. Karena tidak mungkin kita dapat sukses melaksanakan ujian tanpa alat tulis.

5. Hindari Pekerjaan Berat

Pekerjaan yang memungkinkan menggangu konsentrasi anda saat menjelang ujian sangat berpengaruh dalam konsentrasi pola pikir anda karena secara langsung otak menyerap dua tenaga yang berlawanan antara memori dan beban.

6. Melakukan Uji Wawasan Diri Sendiri

Tips yang tidak perlu diragukan lagi keampuhannya, karena dengan menguji wawasan anda dalam mata pelajaran yang akan di ujikan dalam UN, akan membuat anda semakin percaya diri ketika menghadapi soal ujian yang sebenarnya. Try Out online membantu dan bisa dicoba di link ini. 

7. Hindari Cara Melakukan Kecurangan

Banyak cara dalam menempuh kesuksesan dalam ujian. Salah satunya adalah melakukan kecurangan (Mencontek), namun hal ini akan membuat anda bingung dan membuang tenaga karena dengan mencontek pada catatan yang anda buat sebelumnya ataupun anda mencontek kepada teman anda akan butuh membuang memori kerja otak dan tenaga 3 kali lipat dari pada anda mengerjakan dengan usaha dan kemampuan anda sendiri. Jadi, hindari kegiatan contek mencontek dalam pelaksanaan ujian.

8. Berdoa Dan Memohon Agar Pikiran Anda Tenang Dan Terang

Satu hal yang biasa kita lakukan sebelum melakukan aktivitas apaun yakni berdoa. Berdoa atau memohon kepada Tuhan adalah hal yang sangat positif yang dapat menambah rasa percaya diri. So! Jangan lupa anda berdoa sebelum dan sesudah mengerjakan soal ujian.

9. Memohon Restu Kepada Orang Tua, Keluarga, Dewan Guru dan Teman-Teman

Memohon restu kepada semua orang yang telah mendukung kita dapat membuat hati menjadi lebih tenang dan tidak akan merasa tegang ketika menghadapi para pengawas, soal ujian dan kepastian. Salah satu tips ini harus dilakukan oleh siapa saja yang akan menghadapi ujian, karena terbukti ampuh menyalakan rasa tanggung jawab akan jawaban yang telah dijawab.

10. Memperbanyak Ibadah Kepada Allah SWT

Mungkin dari sekian tips, ini adalah tips yang wajib dilakukan. Karena hanya kepada Allah SWT kita pasrah dan menyerahkan segalanya kepada-Nya. Bahkan keajaiban yang akan di munculkan oleh Allah SWT kepada siapa yang taat dan patuh serta selalu menyebut nama-Nya.

Demikianlah beberapa tips yang dapat kami sampaikan khususnya kepada para siswa yang akan melaksanakan ujian nasional tahun pelajaran 2011/2012 dan umumnya kepada kita semua. Tiada maksud untuk menggurui melainkan hanya saling menasehati. Dan kami ingatkan kembali, bahwa kesuksesan dalam suatu pekerjaan apapun tidak akan dapat diraih tanpa doa, usaha, yakin serta ikhtiyar yang maksimal.

DUIT = Doa,Usaha,Ikhtiar,Tawakkal.

Hewan dengan jumlah kaki terbanyak

Nama kaki seribu mungkin layak disandang hewan bernama Latin, Illacme plenipes, ini. Hewan ini pertama kali ditemukan pada tahun 1928 memiliki kaki mencapai 750 buah.

Meski memiliki ratusan kaki, panjang makhluk ini hanya sekitar 3 centimeter. Hewan ini baru ditemukan lagi oleh entomolog dari Universitas Arizona, Amerika Serikat, Paul Marek, di dekat Silicon Valley, baru-baru ini. Marek dan koleganya kemudian mempublikasikan temuan ini dalam jurnal ZooKeys, Rabu 14 November 2012. Marek mengupas tuntas deskripsi makhluk ini, termasuk anatomi anehnya.
Umumnya, kata Marek, spesies kaki seribu hanya memiliki antara 80-100 kaki terpisah. Namun, Illacme plenipes ini benar-benar paling mendekati nama julukannya. Betinanya bisa memiliki kaki mencapai 750 buah, sementara yang jantan lebih dari 550. Bukan hanya, dia juga memiliki sutra yang bisa menutupi badannya sehingga mirip seperti pakaian.
Mareka mencari makhluk aneh ini dengan membongkar bebatuan di kawasan sekitar San Fransisco, Amerika Serikat, antara 2005 sampai 2007 lalu. Ada 17 spesimen yang dikumpulkannya.
Karena hidup jauh di bawah tanah, kaki-kakinya ada yang berevolusi memiliki cakar. Cakar ini diduga sebagai alat untuk bisa bergantung di bebatuan.
Artropoda ini juga memiliki antena yang masif jika dibandingkan dengan ukuran tubuhnya. Mulutnya juga memiliki kemampuan melubangi dan menghisap jaringan tanaman.

10 Fakta Unik Tentang Titanic

Pada Ahad, 15 April 2012, tepat satu abad tenggelamnya kapal Titanic (15 April 1912). Kini, sejumlah misteri masih menyelimuti keberadaan penyebab tenggelamnya kapal yang diklaim takkan tenggelam itu.Tapi, banyak  hal menarik yang perlu kita ketahui tentang Titanic. Yang pasti, sejak tenggelamnya kapal tersebut, ratusan ribu bahkan jutaan bunga diberikan sebagai ucapan belasungkawa atas korban Titanic.
Berikut ini, 10 fakta unik yang perlu kita ketahui dengan tenggelamnya kapal tersebut.

1. Harga-harga tiket yang dijual pada saat Kapal Titanic akan berlayar di tahun 1912 itu senilai 4.350 dolar AS (kelas utama), 1.750 dolar (untuk tiket kelas dua), dan 30 dolar AS untuk tiket kelas tiga.

2. Setelah menabrak gunung es, Titanic masih bertahan untuk mengapung selama 2 jam 40 menit.

3. Interval waktu saat salah seorang awak kapal melihat ada gunung es di depan kapal Titanic sekitar 30 detik.

4. Dengan kapal yang besar dan jumlah penumpang yang mencapai sekitar 2000 orang, maka Titanic membutuhkan 14 ribu galon air minum setiap 24 jam, dan 825 ton batubara per hari untuk pelayaran.

5. Saat pelayaran itu, Titanic membawa 900 ton barang yang ada di kargo bagasi.

6. Dari ribuan penumpang itu, terdapat 13 pasangan yang sedang merayakan honey moon (bulan madu) pernikahan mereka.

7. Sekitar 14 tahun sebelum Titanic berlayar, seorang penulis novel bernama Morgan Robertson pernah membuat novel dengan judul ‘Futility’ (Kesia-siaan) pada 1898. Dalam novelnya itu, Morgan menulis tentang sebuah kapal besar bernama ‘Titan’ menabrak gunugng es di Lautan Atlanticdi malam yang dingin pada bulan April. Entah sekadar menulis atau ahli peramal, faktanya tulisan Morgan benar. Titanic menabrak gunung es di Laut Atlantik pada 15 April 1912.

8. Dalam peristiwa tenggelamnya kapal Titanic itu, terdapat dua ekor anjing yang selamat.

9. Ibarat sebuah bangunan kekaisaran (imperium), Kapal Titanic memiliki luas dan besar bangunan yang sama luasnya dengan istana kerajaan.

10. Kucing biasanya menjadi lambang keberuntungan sebagian orang. Ia kerap dibawa kemana pun pergi, termasuk naik ke kapal untuk berlayar. Ternyata, selama pelayaran, Kapal Titanic tidak membawa seekorpun kucing ada di dalamnya. Pemilik Kapal Titanic tidak mengizinkan kucing untuk mengawasi tikus (hewan pengerat) ada di kapal tersebut. Dan anak buah kapal (ABK) Titanic mengawasi dengan ketat setiap penumpang yang naik ke kapal.

Demikian 10 fakta menarik tentang Titanic, yang saya kutip dari www.tiptoptens.com.

7 Hari Terakhir Sebelum Internet Doomsday

Hari ini adalah tanggal 2 Juli dan merupakan 7 hari terakhir sebelum 'hari kiamat internet' terjadi. 7 hari dari sekarang, semua komputer yang terinfeksi dan terhubung dengan internet tidak dapat mengakses email, Facebook, Twitter, YouTube atau segala alamat di internet.

Menurut Msn.com, FBI menyatakan bahwa mereka bertanggung jawab atas penonaktifan internet pada tanggal 9 Juli mendatang. FBI menyebut hari tersebut dengan sebutan Internet Doomsday atau hari kiamat internet. Mengapa FBI ingin mematikan internet pada tanggal 9 Juli? Hal tersebut dikarenakan laporan sebuah serangan trojan yang akan menyapu bersih semua jaringan internet dunia seperti tsunami.

Trojan yang bernama DNSCharger Trojan tersebut merupakan ciptaan dari cybercriminal dari Estonia. Trojan ini akan menginfeksi semua PC berbasis Windows dan Mac serta merusakrouter yang terhubung dengan internet. Sekarang ini menurut catatan Internetidentity.com, terdapat 4 juta komputer dan router yang terhubung dengan internet.

DNSCharger Trojan juga pernah melumpuhkan kurang lebih 500 ribu PC dan Mac di tahun 2007 silam. Oleh karenanya, FBI menyarankan agar pengguna internet untuk melakukan tiga langkah antisipasi sebelum tanggal 9 Juli mendatang.

• Memeriksa semua pengaturan di dalam komputer
• Menggunakan atau mengaktifkan antivirus terbaik di dalam perangkat komputer
• Memeriksa sistem dalam komputer yang terhubung dengan internet

Tiga langkah di atas memang bukan satu-satunya cara untuk menyelamatkan perangkat komputer kita dari serangan DNSCharger Trojan, namun apa salahnya apabila mencoba langkah-langkah tersebut. Lebih baik menjaga daripada mengobati, bukan?
