<![CDATA[Tujuan penalitian ini adalah menghasilkan bahan ajar matematika melalui pendekatan kearifan lokal pada materi trigonometri yang layak dan sesuai kebutuhan siswa. Jenis penelitian ini adalah Penelitian dan Pengembangan (R&D) dengan menggunakan model ADDIE yang terdiri dari lima tahap, yaitu analyze (analisis), design (perancangan), development (pengembangan), implement (implementasi) dan evaluate (evaluasi). Instrumen yang digunakan yaitu lembar angket validasi ahli materi dan ahli media, angket respon guru matematika, dan angket respon siswa. Berdasarkan penelitian diperoleh hasil validasi ahli dengan persentase 80% (layak), respon guru dengan persentase 79% (baik) dan respon siswa dengan persentase 78% (baik). Secara keseluruhan bahan ajar ini dapat di terima dengan baik oleh guru dan siswa didukung oleh hasil validasi dari para ahli yang menyatakan bahan ajar layak digunakan untuk kegiatan belajar.
