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. Kata kunci: bahan ajar, trigonometri, kearifan lokal ABSTRACT The purpose of this research is to produce mathematics teaching materials through a local wisdom approach to trigonometry material that is appropriate and in accordance with the needs of students. This type of research is Research and Development (R&D) using the ADDIE model which consists of five stages, that is analyze, design, development, implement and evaluate. The instrument used were questionnaire validation sheet material experts and media expert, mathematics teacher response questionnaire and student response questionnaire. Based on the research results obtained by expert validation with a percentage of 80% (feasible), teacher response with a percentage of 79% (good) and responses students with a percentage of 78% (good0. Overall this teaching material can be well received by teachers and studens, supported by validation results from experts who claim teaching materials are suitable for use in learning activities. Keywords: teaching materials, trigonometry, local wisdom
This study aims to describe the extent of mathematical connection skills in terms of student selfconfidence, especially in the Linear Program material. The subjects of this study were as many as 30 tenth grade students of SMK 4 Pandeglang Light Vehicle Engineering Department. The method used in this study is descriptive method with a quantitative approach. The instruments used in this study include the test of mathematical connection ability and self-confidence questionnaire. The research was conducted in three stages, namely preparation, implementation and analysis of data. The results showed that: 1) Overall the mathematical connection ability of students gained an average of 65% which was included in the sufficient category, 2) Students with high self-confidence, the average mathematical connection ability was 86% which was included in the excellent category, 3) Students with moderate self-confidence, the average mathematical connection ability is 63% which is included in the sufficient category, and 4) Students with low self-confidence, the average mathematical connection ability is 47% which is included in the less category.
