SMAN 15 is one of the high school in Surabaya, second most populous city after Jakarta. SMAN 15 Surabaya has many unique exstracurricular, one of them is karawitan. Karawitan is sound art from javanes people which has social and moral values. Karawitan is consist of bonang, kempul, and gambang which we know as gamelan instrument. SMAN 15 must be proud to have students who are interested in this extracurricular because in this modern era student libels still continue to conserve Javanese culture although many teenagers are less interested in karawitan.

According to Alfirca, vice head of karawitan, she explain this extracurricular is new in libels, at the first time only a few students joined this extracurricular, but now there are some libels students who are interested in this extracurricular, around 13 students. When they first started training, they had training schedules every Monday and Thursday, but now they training depends on the teacher, when the coach come to libels the member of karawitan will do routine exercises, but they try to manage time to be able to practice independently even though there are no coach.

They always play gamelan at school pavillion with coach of karawitan and her name is Mr. Gudi who was accompanied by one of the senior who have graduated from libels, Krisna. According to Alfirca, she said karawitan extracurricular must be there in libels because they want to achieve some achievements in the non-academic category to make their school proud of them, but in the otherwise many teachers want students of libels can love and conserve indonesian culture. Actually members of karawitan want to take part in various kinds of competitions, but not now, because they have not prepared well for the competition. Although this extracurricular activity is still new, but it is not an obstacle for them to be able to join the competition, they will do the best and try as much as possible to get achievements to make libels proud.

"Our effort to conserve this Javanese culture is by trying to practice routinely in order to play Javanese gamelan well and also we want to take part in competitions that can help us to improve our abilities so we can play gamelan better," said Alfirca, vice head of karawitan.

We can get many benefit if we want to learn and conserve about our culture, sone of the benefit we can takes is, we can learn how to work together with each other to play gamelan, we know how to respect if there is differents opipinion, we learn how to unity in diversity, etc. If we conserve indonesian culture, our culture cannot be taken over by another country. So It is our responsibility to always potect the culture that we have, and we must proud of indonesian culture.
