Kemampuan pemecahan masalah merupakan salah satu kemampuan matematis yang harus dimiliki siswa dalam pembelajaran matematika. salah satu materi yang dapat melatih kemampuan pemecahan masalah siswa adalah materi bangun datar. pada materi bangun datar, banyak objek dalam kehidupan sehari-hari yang bentuknya beragam selain dari bentuk bangun datar yang dipelajari disekolah, sehingga untuk menghitung luasnya diperlukan rumus bangun datar yang diajarkan di sekolah kemudian pendidik dalam mengembangkan koneksi matematis siswa memunculkan permasalahan terkait koneksi matematis. siswa kemudian akan melalui proses penyelesaian permasalahan tersebut dengan menggunakan prosedur dan langkah-langkah yang tepat. penelitian ini bertujuan untuk mengetahui kemampuan pemecahan masalah ditinjau dari kemampuan koneksi matematis pada materi bangun datar. pendekatan yang digunakan adalah kualitatif dengan jenis deskriptif. subjek penelitian ini sebanyak 6 dari 22 siswa yang mewakili kategori tinggi, sedang dan rendah. instrumen pada penelitian ini selain penelitian sebagai instrumen utama, dibantu juga dengan instrumen pendukung berupa lembar tes dan wawancara. data dianalisis dengan konsep reduksi data, penyajian data, dan penarikan kesimpulan. hasil penelitian diperoleh bahwa dari 22 orang siswa yang dijadikan subjek, terdapat 13 (59%) siswa dengan kategori sedang. artinya siswa bersangkutan memiliki kemampuan pemecahan masalah dengan sudah mampu mengkaitkan koneksi matematis dalam memecahkan masalah baik dengan cara memahami masalah sampai memerika kembali namun penyelesaian subjek tidak menuliskan jawabannya secara rinci. siswa dengan kategori tinggi sebanyak 3 (14%), artinya siswa tersebut memiliki kemampuan pemecahan masalah dengan sudah mampu mengkaitkan dengan koneksi matematis, namun hanya pada aspek memahami masalah dan merencanakan penyelesaian namun melaksanakan rencana dan memeriksa kembali hanya dapat dipenuhi pada beberapa soal. siswa dengan kategori rendah sebanyak 5 (22%). artinya siswa tersebut belum memiliki kemampuan pemecahan masalah dengan mengkaitkan melalui koneksi matematis dalam menyelesaikan soal tes yang diberikan. implikasi penelitian ialah agar guru dan siswa memperhatikan dan meningkatkan kemampuan koneksi matematis untuk dapat membantu siswa dalam menyelesaikan soal – soal dan permasalahan pembelajaran yang diberikan guru. kata kunci: bangun datar, kemampuan pemecahan masalah, koneksi matematis

Problem solving ability is one of the mathematical abilities that students must have in learning mathematics. One material that can train students' problem solving skills is flat shape material. In the material about flat shapes, there are many objects in everyday life that have various shapes apart from the flat shapes that are studied at school, so to calculate the area, a flat shape formula is needed which is taught at school, then educators in developing students' mathematical connections raise problems related to mathematical connections. Students will then go through the process of solving the problem using appropriate procedures and steps. This research aims to determine problem solving abilities in terms of mathematical connection abilities in plane material. The approach used is qualitative with a descriptive type. The subjects of this research were 6 out of 22 students representing the high, medium and low categories. The instruments in this research, apart from research as the main instrument, are also supported by supporting instruments in the form of test sheets and interviews. Data were analyzed using the concepts of data reduction, data presentation, and drawing conclusions. The research results showed that students with a high category of problem solving ability were able to link mathematical connections in solving problems both by understanding the problem and examining it again, but in solving the subject they did not write down the answer in detail. The research results showed that of the 22 students who were subjects, there were 13 (59%) students in the medium category. This means that the student concerned has problem solving abilities by being able to relate mathematical connections in solving problems both by understanding the problem and examining it again, but when solving the subject, he does not write down the answer in detail. Students in the high category were 3 (14%), meaning that these students had problem solving abilities and were able to relate mathematical connections, but only in the aspect of understanding the problem and planning a solution but carrying out the plan and checking again could only be fulfilled on a few questions. Students in the low category were 5 (22%). This means that the student does not yet have the ability to solve problems by connecting through mathematical connections in solving the test questions given. The implication of the research is that teachers and students pay attention to and improve their mathematical connection abilities to be able to help students solve learning questions and problems given by the teacher.
