Tayangan kartun bagi anak-anak Indonesia

Baru-baru ini seperti yang diberitakan di beberapa media massa, Komisi Penyiaran Indonesia (KPI) mengeluarkan statemen bahwa beberapa judul kartun seperti Detective Conan, Naruto, dan Bleach tidak cocok untuk anak-anak. Dengan titik berat perlindungan terhadap anak-anak, ditengarai tayangan tersebut bisa membawa pengaruh negatif terhadap anak-anak. Bagaimana tayangan ini bisa berjalan selama bertahun-tahun di jam-jam buat anak-anak dan apa yang harus kita lakukan sebagai orang tua?

The positive aspects of Western education system (part 2)

The next positive things is on the way the teachers motivate students. Teachers like to give compliments and rewards to the students no matter how small the progress. Using “carrot and stick” principle, more “carrots” are offered for the students. This could strongly motivate the students to strive for their best, particularly during the early ages. However, one could argue that the “stick” is still very important for some reasons that I will write later on the positive aspects of Asian education system.

Jenis raw material yang cocok untuk industri fermentasi (bagian 1)

Teknologi fermentasi oleh mikroorganisme memegang peranan vital dalam industri kimia dunia yang bernilai lebih dari dua trillion USD. Salah satu faktor utama di industri fermentasi adalah jenis bahan pokok atau raw material.

Berdasarkan kemurnian, raw material dibedakan menjadi dua yaitu material murni dan campuran. Material murni digunakan sebagai bahan baku pembuatan media fermentasi jenis mineral media sehingga bisa juga dikatakan sebagai media sintetik. Sedangkan material campuran dipakai sebagai media fermentasi jenis complex media. Mineral media merupakan campuran dari garam-garam (misalnya sodium atau potassium phosphate atau sulphate), trace metal ions, ammonium sebagai sumber nitrogen, vitamin, dan gula sebagai sumber karbon dan energi. Media kompleks sendiri merupakan campuran dari beratus-ratus bahkan bisa ribuan senyawa dalam satu larutan atau suspensi, umumnya berasal dari sisa proses kimia. Media kompleks bisa berupa molasses, limbah industri susu, bahan-bahan selulosa (batang padi, jerami), bagasse, dan lain-lain.

Lalu, jenis raw material apa yang baik untuk industri fermentasi?

The positive aspects of Western education system (part 1)

Each education system certainly has its own pros and cons. However, I prefer to discuss about the positive aspects of each, starting from the Western system.

One of these positive things is the the system allow many opportunities for the student to present his/herself in front of the class. My kids always have a show and tell session at least once every week where they can show and tell a story about something they have or they like to do. For example, they bring their toy and tell their teachers and friends why they like it or how to play with it. It is their favorite session. By this, the children can learn a good communication skill since they are very young. They also can learn on how to be a good listener and respect other’s idea. It will also improve the self confidence. In addition, it will make the children become more creative simply because they have a freedom the express themself in both oral or written. Self actualisation is one of the main basic needs.

The second part I will talk about how teachers motivate the students. Just wait!

The Silk Road

There are many favorite places I want to go. The Silk Road is one of them. Why? There are many reasons. Many people may not know this place because it is mostly located in the heart of Eurasian continent.

The best jet fighters from the USA, Russia, and China

Jet fighters are always my favorite but I am not the expert. Since the top 3 military powers are USA, Russia, and China both in quality and quantity, I think it is fair enough to compare the best jet fighter of each country that are F-22 Raptor (USA), Su-33 Flanker (Russia), and J-10 Dragon (China).
