Peningkatan Hasil Belajar melalui Model Problem Based Learning Materi Trigonometri Kelas X Tata Busana

This research is a Classroom Action Research. The research subjects were students of class X Fashion Design 2 SMK Negeri 2 Temanggung in 2019/2020, totaling 36 students consisting of 36 female students and 0 male students. The instruments used in this study were test instruments and non-test instruments. The non-test instruments consist of observation sheets, field notes and documentation. The data collection technique was done by using test techniques and non-test techniques. Analysis and data processing using quantitative techniques and qualitative techniques. The research was carried out in two cycles with each cycle consisting of four stages, namely planning, action, observation and reflection. The average individual test score increased from 61.53 in cycle 1 to 88.15 in cycle 2. Completeness of classical learning also increased by 66.7% from 33.3% to 100%. The research results have been able to answer the problem formulation, achieve research objectives and prove the research hypothesis, namely the use of Problem Based Learning can improve learning outcomes on Trigonometry material.ABSTRAK Penelitian ini merupakan Penelitian Tindakan Kelas. Subjek penelitian adalah siswa kelas X Tata Busana 2 SMK Negeri 2 Temanggung Tahun 2019/2020 yang berjumlah 36 siswa terdiri dari 36 siswa perempuan dan 0 siswa laki-laki. Instrumen yang digunakan dalam penelitian ini adalah instrumen tes dan instrumen non tes. Instrumen non tes terdiri dari lembar observasi, catatan lapangan dan dokumentasi. Teknik pengumpulan data dilakukan dengan teknik tes dan teknik non tes. Analisis dan pengolahan data menggunakan teknik kuantitatif dan teknik kualitatif. Penelitian dilaksanakan sebanyak dua Siklus dengan masing-masing Siklus terdiri dari empat tahap yaitu perencanaan, tindakan, observasi dan refleksi. Rata-rata nilai tes individual naik dari 61,53 pada Siklus 1 menjadi 88,15 pada Siklus 2. Ketuntasan belajar klasikal juga naik 66,7 % dari 33,3% menjadi 100%. Hasil penelitian telah mampu menjawab perumusan masalah, mencapai tujuan penelitian dan membuktikan hipotesis penelitian yaitu penggunaan Problem Based Learning dapat meningkatkan hasil belajar pada materi Trigonometri. ABSTRACT This research is a Classroom Action Research.
