Pengembangan LASMATH (Labirin SPLDV Matematika) Untuk Memperkuat Numerasi Peserta Didik pada Materi SPLDV

Development of LASMATH (Mathematics SPLDV Labyrinth) to Strengthen Numeration of Junior High School Students on SPLDV Material

Penelitian ini bertujuan untuk mengembangkan media pembelajaran LASMATH pada materi Sistem Persamaan Linier Dua Variabel untuk memperkuat numerasi peserta didik dan mengetahui hasil pengembangan media pembelajaran yang ditinjau dari kevalidan, kepraktisan, dan keefektifan. Penelitian ini menggunakan model pengembangan ADDIE yang terdiri dari 5 tahap yaitu Analysis dilakukan analisis kebutuhan, analisis kurikulum, analisis peserta didik, dan analisis media. Tahap Design dilakukan mencari ide nama aplikasi, menyusun flowchart, menyusun storyboard, desain background, dan menyusun soal. Tahap Development dilakukan pengembangan media pembelajaran LASMATH, validasi ahli media dan ahli materi, revisi media. Tahap Implementation dilakukan pengimplementasian kepada peserta didik  kelas VIII SMP Negeri 1 Mantup. Tahap Evaluation dilakukan kegiatan menganalisis hasil dari penelitian yang telah dilakukan. Berdasarkan hasil validasi yang telah dilakukan, LASMATH dilakukan validasi media oleh ahli media dengan nilai validasi tahap I sebesar 73% dengan kriteria kurang valid dan direvisi kembali serta perbaikan media dihasilkan nilai 77% dengan kriteria valid pada validasi tahap II. Validasi ahli materi tahap I mendapatkan  nilai 77% dengan kriteria valid namun ada beberapa indikator yang belum terpenuhi jadi dilakukan validasi tahap II diperoleh nilai 80% dengan kriteria valid. Uji coba media pembelajaran dilakukan pada 28 peserta didik kelas VIII  SMP Negeri 1 Mantup. Hasil dari penelitian setelah diujicoba dan dievaluasi, menunjukkan media pembelajaran ini dikatakan praktis karena berdasarkan persentase angket respon peserta didik diperoleh 82,7% dengan kriteria praktis. Media pembelajaran dikatakan efektif dan terdapat perbedaan signifikan dari hasil data nilai peserta didik sebelum dan sesudah menggunakan media pembelajaran LASMATH dibuktikan juga oleh rata-rata nilai N-Gain sebesar 0,70 dapat dikatakan bahwa media pembelajaran LASMATH ini efektif dengan kategori sedang. 

This research aims to develop LASMATH learning media on Two Variable Linear Equation Systems material to strengthen students' numeracy and find out the results of learning media development in terms of validity, practicality and effectiveness. This research uses the ADDIE development model which consists of 5 stages, namely needs analysis, curriculum analysis, student analysis and media analysis. The Design stage involves looking for ideas for application names, compiling flowcharts, compiling storyboards, background designs, and compiling questions. The Development stage carried out the development of LASMATH learning media, validation of media experts and material experts, media revision. The implementation stage was implemented for class VIII students at SMP Negeri 1 Mantup. In the Evaluation stage, activities are carried out to analyze the results of the research that has been carried out. Based on the results of the validation that has been carried out, LASMATH carried out media validation by media experts with a validation value in stage I of 73% with criteria that were less valid and revised again and improvements to the media resulted in a value of 77% with valid criteria in stage II validation. Stage I material expert validation got a score of 77% with valid criteria but there were several indicators that were not met so stage II validation was carried out and obtained a score of 80% with valid criteria. Learning media trials were carried out on 28 class VIII students at SMP Negeri 1 Mantup. The results of the research, after being tested and evaluated, show that this learning media is said to be practical because based on the percentage of student response questionnaires, it was found to be 82,7% with practical criteria. The learning media is said to be effective and there is a significant difference in the data results of students' scores before and after using the LASMATH learning media as evidenced by the average N-Gain value of 0,70. It can be said that the LASMATH learning media is effective in the medium category.
