Penelitian ini bertujuan untuk mengetahui tingkat dan faktor yang mempengaruhi kemampuan penalaran proporsional menurut Langrall dan Swafford pada siswa sekolah menengah pertama. Penelitian ini merupakan penelitian kualitatif analisis deskriptif yang dilakukan pada siswa kelas VIII di SMP Negeri 13 Bandung Tahun Ajaran 2020/2021. Teknik pengumpulan data dilakukan dengan memberikan tes kepada 25 siswa. Kemudian melakukan wawancara. Hasil penelitian siswa dapat mengerjakan soal perbandingan senilai dan berbalik nilai dengan mampu melakukan penalaran proporsional menurut Langrall dan Swafford pada level 2 dan level 3. Selanjutnya, faktor yang mempengaruhi kemampuan penalaran proporsional menurut Langrall dan Swafford pada siswa adalah bagaimana siswa dapat mengingat materi yang sudah diajarkan sebelumnya, cara guru mengajarkan materi tersebut dan bagaimana fasilitas yang diberikan oleh orang tua siswa. Berdasarkan hasil penelitian menunjukkan bahwa siswa dapat mengerjakan soal perbandingan dengan mampu melakukan penalaran proporsional menurut Langrall dan Swafford pada level 2 dan level 3 dan faktor yang mempengaruhi kemampuan penalaran proporsional menurut Langrall dan Swafford siswa adalah faktor internal (seperti motivasi, minat, bakat, dan kemampuan memahami pembelajaran matematika dan faktor eksternal (seperti fasilitas yang diberikan kepada siswa dan cara pengajaran guru kepada siswa). This research aims to determine the levels and factors that affect proportional reasoning skills according to Langrall and Swafford in junior high school students. This research is a qualitative descriptive analysis conducted on class VIII students at SMP Negeri 13 Bandung for the 2020/2021 academic year. The data collection technique was carried out by giving tests to 25 students. Then do an interview. The results of the research of students being able to work on comparative questions of value and turning value by being able to do proportional reasoning according to Langrall and Swafford at level 2 and level 3. Furthermore, the factors that affect proportional reasoning abilities according to Langrall and Swafford in students are how students can remember the material that has been taught. previously, how the teacher taught the material and how the facilities provided by the parents of students. Based on the results of the study, it shows that students can work on comparative questions by being able to do proportional reasoning according to Langrall and Swafford at level 2 and level 3 and the factors that affect proportional reasoning abilities according to Langrall and Swafford students are internal factors (such as motivation, interests, talents, and abilities to understand mathematics learning) and external factors (such as the facilities provided to students and the way teachers teach students).
