Game Edukasi Pengenalan Dan Perhitungan Angka Dalam Operasi Hitung Penjumlahan Dan Pengurangan Untuk Murid Sekolah Dasar Penyandang Tunagrahita Di SLB Negeri Sukoharjo

One of the advantages of this technological development is that it facilitates the learning process, because education is an important part of human life. The learning process itself should be done from an early age (1-5 years). However, not all children have the same way of learning, those who have limitations in the development of their intelligence will certainly need different treatment to develop and obtain maximum education. The Sukoharjo State Special School uses conventional methods based on the K13 curriculum by teaching students directly, but there are still students who have to be given explanations repeatedly. In addition, there are students who are still confused in carrying out addition and subtraction arithmetic operations and must use concrete objects to make it easier to carry out arithmetic operations. Facing these problems, the authors took the initiative to create new learning media by developing math educational games that would make mathematics more fun and easy to explain at the Sukoharjo State Special School. The game created will have a feature to display the shape of concrete objects from numbers so students can better understand the arithmetic operations that are displayed. This study used the Game Development Life Cycle (GDLC) method and collected data by interviews and direct observation. Assets created using Adobe Illustrator, Adobe Photoshop, and Figma. Meanwhile, the background music and voice for number recognition are made by taking sources from the internet based on the input entered by the author. This research resulted in the Pejuang Matematika game which received an Excellent rating based on the SUS Score (85.25 / B). With this in mind, it can be concluded that the Mathematics Warriors have achieved a high enough quality level to support the learning process at the Sukoharjo State SLB
