Abstrak
Penelitian ini didasari oleh rendahnya kemampuan berpikir kreatif matematis siswa yang disebabkan oleh model pembelajaran yang digunakan oleh guru belum dapat meningkatkan kemampuan berpikir kreatif matematis siswa, pendekatan yang masih konvensional sehingga pembelajaran masih terfokus pada guru yang membuat siswa pasif dalam pelajaran. Model Treffinger menuntut kemampuan guru untuk meningkatkan kemampuan berpikir kreatif matematis siswa yang terdapat tiga langkah, yaitu guru memberikan pertanyaan yang berhubungan dengan materi, siswa diberikan waktu untuk berdiskusi guna mengisi lembar kerja siswa (LKS) dan mencari alternatif penyelesaian, tahap akhir siswa diberikan masalah yang terdapat dalam kehidupan nyata. Penelitian ini merupakan penelitian tindakan kelas (PTK) dengan model Kemmis dan Mc Taggart yang mencakup perencanaan, pelaksanaan tindakan, obeservasi hingga refleksi yang dilakukan kepada siswa kelas VIII SMP Plus Assa'adah Serang dengan dua siklus. Setiap siklusnya terdiri dari tiga pertemuan yang bertujuan untuk meningkatkan kemampuan berpikir kreatif matematis siswa. Berdasarkan penelitian, kemampuan berpikir kreatif matematis siswa meningkat. Pada siklus I, nilai rata-rata tes siswa sebesar 58,39 yang dikategorikan 11,54% rendah dan 88,46% sedang. Pada siklus II, nilai rata-rata tes siswa sebesar 78,46 yang dikategorikan 52,17% sedang dan 47,93% tinggi, tidak terdapat siswa dengam kemampuan berpikir kreatif matematis yang rendah.

This research is based on the low ability of students to think creatively mathematically caused the learning model used by the teacher has not been able to improve students' mathematical creative thinking skills, a conventional approach so that learning is still focused on the teacher which makes students passive in the lesson. Treffinger's model demands the ability of the teacher to improve students' creative thinking skills in three steps, namely the teacher gives questions related to the material, students are given time to discuss in order to fill student worksheets (LKS) and look for alternative solutions, the final stage students are given problems that there is in real life. This research is a classroom action research (CAR) with the Kemmis and Mc Taggart models which includes planning, implementing actions, observing to reflections made to eighth grade students of SMP Plus Assa'adah Serang with two cycles. Each cycle consists of three meetings which aim to improve students' creative thinking skills. Based on research, students' mathematical creative thinking skills increase. In cycle I, the average test score of students was 58.39 which was categorized as 11.54% low and 88.46% moderate. In cycle II, the average score of students' test was 78.46 which was categorized as 52.17% medium and 47.93% high, there were no students with low mathematical creative thinking abilities.
