Introduction
The development of ICT IS very rapidly this decade, it should be taken seriously in order to bring a positive impact in print prospective educator who is professional and has good characteristics. Concrete steps done by the University PGRI of Semarang and Semarang Sultan Agung Islamic University in facing this challenge are as follows: (1) providing computer labs in each study program, (2) completing a computer device in the form of hardware and software in every classroom, (3) conducting training for lecturers to be able to master ICT in learning in a good and right manner. But in reality there is still a few of lecturer who apply ICT in the learning process. Based on data from interviews with several professors of mathematics in University PGRI of Semarang and Semarang Sultan Agung Islamic University, it found that students' interest in the subject of High School Mathematics is still low, it is because the lecturers have not been able to pack maximum learning, especially in using math hardware and software. Low interest can make learning becomes less than optimal. This is because students are less active for participating in the learning process. Interactive and fun learning media can increase student interest in learning [1]. The technology that is now developing can support the independent learning process, one of them is computer.
Computers can be used as a medium of learning. According to Wankat and Oreonovicz, as cited by Wena [2], one of the advantages of learning by using computer as learning media is to stimulate students to do the exercise because of the availability of (1) graphics animated, (2) color, and (3) music. Computer, notebook, or laptop is not a luxury item anymore, so a lot of people who already have a computer.
Therefore, a computer learning media can facilitate students to learn independently. Students can learn to use a computer either on campus or at home. Game is one thing that is liked by children. With the development of the existing technology then comes the computer game. In the computer game, there are several elements that can drive a person to linger to play. These elements of which are a great view, great content, and joy when completing a level or stage to get to the next level.
In the e-book "Learning in Immersive worlds A review of gamebased learning", Sara de Freitas [3] explains some of the functions of the game, namely: (1) to motivate and engage learners in learning activities (2) to train skills or assignment (3) to provide therapy to relieve pain and cognitive difficulties (4) to play the role of a particular job and profession prior to practice in real life (5) to empower learners as a writer and producer of multimedia, mixed media and contentbased games. Then clarified by Burguillo [4] on 'Using game theory and competition based learning to stimulate student motivation and performance Computers & Education' shows that the presence of the game in learning makes students motivated and their computer capability increases. Then in this case it needs to be done planting local culture associated with math, Muhammad [5] explains that the local culture that is packed with digital computers make students understand and get to know the local culture easily. Then amplified by Hwang and Wu [6], which indicates the digital game based learning from 2001 to 2010 rise in the British territory. Then amplified by Ebner and Holzinger [7], which explains that a computer based educational game can increase student interest in learning. Further educational games can also improve motivation to learn [8], so Garris [9] proved if Games with mobile can make student have more motivation at learning any lesson. And then Cheng et al. [10], showed student made high motivation, Engagement and Learning through Digital Games, basic statement Panoutsopoulos [11] showed A Study on Exploiting Commercial Digital Games into School Context more positive effect to student and Kebritch [12] proved the pedagogical foundations of modern educational computer games more effective and make student happy.
Based on these descriptions, then the problem can be formulated as follows: (1) how to develop digital media of math game with ethnomathematics model with the javanese local wisdom based that is valid used at the University of PGRI Semarang and Semarang Sultan Agung Islamic University? and (2) whether the learning with the use of digital math game with the ethnomathematics model with javanese local wisdom -based can take place effectively and practically?

Media digital math game
Computers as electronic media, today have a variety of functions. Some of the benefits of the computer are typing, editing a song, image and communication. Computers also have benefits in the field of education, namely as a medium of learning. Some functions of computer-based learning media according to Wena [2] are an exercise, tutorials and simulations.
Digital game is one of the interactive media used by children as a means to learn and play [5]. A game is liked by children. Children prefer to spend hours and hours to play than to study. Now this game is already in electronic media thus now known the term computer games and online games. Not only children who love the game but teens and adults also love it. Therefore, the game can be used as a tool for learning. This is done by inserting the learning materials inside the game or combining them.
In use, not all games can be used as teaching material, in this case is the medium of learning. There are several things to consider when developing the game as a teaching material. Based on "Learning Material Development Guide", Ministry of Education explains that there are four evaluation components for teaching materials that have been developed. These components are, namely (1) the feasibility of content, (2) linguistic, (3) serving, and (4) graphs.

Ethnomathematics model
Shirley [13], argued that the present ethnomathematics field, namely mathematics that arise and grow in the community and in accordance with the local culture, is a center of learning and teaching methods. This opens up the pedagogical potential that consider the students' knowledge gained from learning outside the classroom. Mathematics essentially grew out of the skill or activity in cultural environment [14], so that someone's mathematics influenced by his cultural background. Mathematics growing within the community is called ethnomathematics by the Bishop. "Ethnomathematics in the elementary classroom is where the teacher and the student's value cultures, and cultures are linked to curriculum". Ethnomathematics is a complex and dynamic representation that describes the cultural influence of the use of mathematics in their applications. Research subject According Tuckman [15] to choose subject can use stratified random sampling any private university in Semarang, the population in this study were all students of fourth semester of Mathematics Education Study Program of University PGRI of Semarang and Semarang Sultan Agung Islamic University in 2015 and 2016 school year.

Research Design
The research design used in this study is a Borg and Gall model [16] with 10 stages, namely (1) the potential and problems, (2) Data collection, (3) the design of the product, (4) Validation of design, (5) Revision of design, (6) product trial, next in the second year are implemented stage 7-10 namely (7) Revision of design (8) trial usage (9) products revision, (10) of mass-production ( Figure 1).

Media design of digital math game
It have produced digital design of math games systematically using Adobe Flash CS 6 and Corel Draw, instrumental music, and ratings so that the product is more refined and tidy, then local wisdom taken were from Central Java games (Figure 2). The results of feasibility by material validation shows the percentage of the general aspects are 95% and 90%, the aspect of material substance are 88% and 90%, aspects of learning design are 93% and 91%. From the calculation of the level of achievement of learning media obtained a percentage of 91%. A percentage that has been obtained is then transformed into a sentence which is qualitative. To be able to give meaning and decision-making is used precision as an indicator of the success of expert validation of learning materials. The results showed that the indicator percentage between 81% -100% on the criterion of "Very Good". So that the test from material experts the percentage is successful or feasible (Figure 3 and Figure 4). The results of the feasibility of media validation shows the percentage of general aspects 95% and 85%, feasibility aspects of the content of 80% and 80%, aspects of the presentation of learning 84% and 84%, feasibility aspects of language 80% and 80%, the feasibility aspects of graphs 80% and 85%, From the calculation of the level of achievement of learning media obtained a percentage of 81%. A percentage that has been obtained is then transformed into a sentence which is qualitative. To be able to give meaning and decision-making is used precision as an indicator of the success of expert validation of learning media. The results showed that the indicator percentage between 81% -100% on the criterion of "Very Good". So the test of media expert of the percentage is successful or feasible.

Result of expert validation
Based on the results the feasibility percentage of media validation and validation of the material showed a range between 81% -100% so that the Digital Math Game media with ethnomathematics models is classified as very well criteria.
