N2  - Penelitian ini bertujuan untuk mengetahui pengaruh model problem based learning
terhadap kemampuan pemecahan masalah matematis siswa. Populasinya adalah
seluruh siswa kelas VIII SMP Negeri 22 Bandar Lampung semester genap tahun
pelajaran 2023/2024 yang terdistribusi dalam sepuluh kelas yaitu VIII-1 sampai
VIII-10. Pengambilan sampel dilakukan dengan teknik cluster random sampling
dan terpilih siswa kelas VIII-6 sebanyak 32 siswa sebagai kelas eksperimen dan
kelas VIII-10 sebanyak 31 siswa sebagai kelas kontrol. Desain penelitian yang
digunakan adalah pretest-posttest control group design. Data penelitian ini berupa
data kuantitatif yang diperoleh dari tes kemampuan pemecahan masalah matematis
siswa. Data dianalisis menggunakan uji statistik yaitu uji-t. Berdasarkan hasil
analisis data, diperoleh bahwa peningkatan kemampuan pemecahan masalah
matematis siswa yang mengikuti model problem based learning lebih tinggi
daripada kemampuan pemecahan masalah matematis siswa yang mengikuti
pembelajaran konvensional. Dengan demikian, model problem based learning
berpengaruh terhadap kemampuan pemecahan masalah matematis siswa.
Kata kunci: kemampuan pemecahan masalah matematis, pengaruh, problem based

This research aims to determine the effect of the problem based learning model on
improving students' mathematical problem-solving abilities. The population in this
study was all students in class VIII of SMP Negeri 22 Bandar Lampung, even
semester of the 2023/2024 academic year, distributed in ten classes, namely VIII-1
to VIII-10, heterogeneously. Sampling was carried out using a cluster random
sampling technique, and 32 students in class VIII-6 were selected as the
experimental class and 31 students in class VIII-10 were selected as the control
class. The research design used was a pretest-posttest control group design. This
research data is in the form of quantitative data obtained from tests of students'
mathematical problem-solving abilities. Data analysis uses a statistical test,
namely the t-test. Based on the results of research, it was found that the increase in
students' mathematical problem-solving abilities in the experimental class was
higher than the increase in students' mathematical problem-solving abilities in the
control class. Based on this, it can be concluded that the problem based learning
model has an effect on improving students' mathematical problem-solving abilities.
