Abstract

The ability to understand mathematics in children with special needs (CSN) needs to be constantly improved. Because the capabilities of CSNs are not the same, they should be grouped based on the results of the evaluations that have been carried out. The purpose of this study is to group children with special needs who receive therapy at Mutiara Al Islam Therapy based on the progress of their mathematical skills. For grouping, use the K-Means Algorithm because this method can be effective in grouping data. Data was obtained from the Mutiara Al Islam therapy institution in Surakarta. The data is in the form of initial math skill scores and new math skill scores, the next process is calculated as a percentage increase in intentions, then clustered. The result of this study is the formation of 2 clusters, namely low improvment and high improvment, so that it can help therapists to improve CSN math skills based on the results of the cluster. Based on the results of the silhouette validity test, the accuracy level of cluster 1 is 0.575629 and cluster 2 is 0.471283.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan literasi dini anak-anak melalui metode bermain sambil belajar di PAUD Kenanga, Desa Banaran. Literasi dini merupakan salah satu kemampuan penting yang harus ditanamkan sejak usia prasekolah, namun pelaksanaannya seringkali kurang menarik sehingga anak-anak mudah bosan. Oleh karena itu, tim pengabdian merancang serangkaian kegiatan edukatif berbasis permainan yang menyenangkan dan sesuai dengan perkembangan usia anak. Metode yang digunakan adalah partisipatif dan demonstratif, dengan langkah-langkah berupa observasi awal, koordinasi dengan guru, pelaksanaan permainan edukatif (mengenal huruf dengan kartu, berhitung dengan balok angka, bermain peran sederhana, membaca buku cerita bergambar, dan membentuk clay), serta evaluasi melalui pengamatan perkembangan anak. Hasil kegiatan menunjukkan bahwa anak-anak lebih aktif, antusias, dan berani berpartisipasi dalam aktivitas literasi. Guru-guru juga menyambut baik metode yang diterapkan dan berencana melanjutkannya secara rutin. Kegiatan ini diharapkan dapat menjadi model pembelajaran alternatif yang menarik untuk meningkatkan literasi anak sejak usia dini.
