PENGEMBANGAN GAME EDUKASI “C-ZERO TREK” SEBAGAI MEDIA LATIHAN SOAL OPERASI BILANGAN CACAH SISWA SLOW LEARNER SMP

DEVELOPMENT OF C-ZERO TREK EDUCATIONAL GAME AS A PRACTICE MEDIA FOR WHOLE NUMBER OPERATIONS FOR SLOW LEARNER STUDENTS IN JUNIOR HIGH SCHOOL

Operasi bilangan cacah merupakan materi yang penting namun cukup menantang bagi siswa slow learner tingkat SMP, mengingat salah satu karakteristik mereka yaitu mudah kehilangan fokus dan membutuhkan pembelajaran yang berulang. Penelitian ini bertujuan untuk mengembangkan game edukasi sebagai media latihan soal yang valid, praktis, dan efektif. Subjek penelitian terdiri dari 9 siswa slow learner SMP, dengan objek berupa game edukasi C-Zero Trek yang dikembangkan menggunakan model ADDIE. Instrumen penelitian meliputi lembar validasi, angket respon, observasi, dan tes. Hasil penelitian menunjukkan bahwa game edukasi C-Zero Trek tergolong “sangat valid” berdasarkan hasil validasi ahli media (98,33%) dan ahli materi (96,66%). Berdasarkan hasil angket respons siswa, diperoleh rata-rata skor indikator pernyataan (SIP) sebesar 82,4%, sehingga game dinyatakan “praktis”. Dari hasil implementasi, diketahui bahwa 77,78% siswa mencapai ketuntasan minimal (menyelesaikan minimal satu trek atau memperoleh dua berlian), sehingga game edukasi C-Zero Trek juga memenuhi kriteria “efektif”. Sehingga, C-Zero Trek layak digunakan sebagai media latihan soal operasi bilangan cacah bagi siswa slow learner. 

Whole number operations are an important yet challenging topic for junior high school slow learners, given their tendency to lose focus easily and require repeated instruction. This study aims to develop an educational game as a valid, practical, and effective practice tool. The research subjects consisted of 9 slow learner students, with the object being the C-Zero Trek educational game developed using the ADDIE model. Research instruments included validation sheets, student response questionnaires, observations, and tests. The results showed that the C-Zero Trek educational game was categorized as “highly valid” based on media expert validation (98.33%) and material expert validation (96.66%). Based on the student response questionnaire, the average score of statement indicators (SIP) was 82.4%, indicating that the game was “practical.” Implementation results showed that 77.78% of students achieved the minimum level of mastery (by completing at least one track or earning two diamonds), meaning the C-Zero Trek game also met the “effective” criteria. Therefore, C-Zero Trek is suitable to be used as a practice tool for whole number operations for slow learner students.
