INTRODUCTION
In this era of globalization, young people prefer modern music than traditional music and rarely find traditional musical instruments. Music art lessons that use traditional musical instruments for children are also rarely found. Based on research, teachers felt that they did not have enough expertise to teach music art material so some teachers agreed that music art was omitted from the curriculum [1].
Some indigenous Indonesian cultures have been known abroad. For example batik, reog ponorogo, gamelan etc. There are even neighboring countries that claim that culture is their country's native culture. A typical Javanese musical instrument, gamelan has become an international conversation because the gamelan is claimed by other countries as its original culture [2]. This is caused by technological advancements that facilitate ways to imitate / adopt and attenuate boundaries between countries so that a cultural / copyright regulation belonging to a country protected by a world body that oversees culture in this case is UNESCO (Union of countries ) Education, Science and Culture Organization.
The younger generation does not respect and preserve traditional Javanese musical instruments because of the monotonous rhythm. The younger generation prefers to follow the flow of western culture and modernization. They assume that traditional music is not trendy and old-fashioned [3]. The decreasing interest of young people, especially in Java to see performances of Javanese art, is evidence of these things.
The flow of globalization that has resulted in the entry of foreign cultures is a strong attraction for the younger generation. This is also the reason why young people are less interested in traditional music. Though traditional music is a national cultural identity that must be considered by society, not just the government [4].
Many foreigners come to Indonesia to learn traditional music because traditional music abroad is more famous there than in their own country. They come to learn and then develop in their respective countries. If this is left unchecked then it is possible that our traditional music will be taken and lost [5].
It is important to preserve traditional music culture in Indonesia so that culture remains and is not lost due to globalization. Community care is also needed in the preservation of traditional music culture.
How to provide learning so as not to be monotonous and fun is done by making the game a learning medium. Primary students like to learn where they can play and learn. It is hoped that by using the game as a medium of learning about traditional musical instruments, students can care more and have a sense of belonging to their culture in their own country [6].
Learning about traditional musical instruments using games has the advantage that students pay more attention, are not bored with lessons, learning will be more alive, and more. Traditional musical instruments in the game that will be made by researchers are traditional musical instruments in Central Java, including Solo and Yogyakarta, which are peking, saron, demung, slenthem, kempul, gong, bonang, gambang, gender, rebab, siter, dan kendang (gamelan).

METHOD
The problem taken by researchers is cultural and social problems, and therefore researchers choose research methods that are qualitative and quantitative.
According to Nana Sudjana and Ibrahim (2001: 84), population is all data that has the opportunity to provide information that can be used by researchers [7]. The population in this study involved 41 students in elementary schools in the city of Semarang.

Figure 1 Research Flowchart
The research began with the study of literature. Followed by the interview stage to the resource person. After that the researchers conducted a review of several existing similar games. Then the researchers began designing the game using the data that had been collected. Then the researchers looked at and consulted the games that had been designed whether they were suitable or not to the mentor. If it is not right for the researcher to do the redesign, if appropriate the researcher conducts the test by distributing the questionnaire. After obtaining data from testing, the researcher processes the data. Then the information obtained from processing the data was made by the researcher as a reference whether or not to make improvements to the game. If repairs are needed, the researcher will correct the game and will retest, if there is no improvement, the game enters the finalization or outcome stage.
