ABSTRACT
The research aims to know the effect of problem based learning on
students’ science process skill and learning outcomes at human excretory system
topic. This research was carried out in SMA Negeri 5 Binjai. This research used
quasi experiment type with pretest-posttest control group design. Population is
the whole students in grade XI SMA Negeri 5 Binjai on 2nd semester, consisting
of three classes. Sample was taken using technique of cluster random sampling.
The number of research sample is 30 students for experiment class and 30
students for control class. The data of learning outcomes is taken by using
instrument test in form of multiple choice which has been tested for the validity
and reliability, while the data of Science Process Skill is taken by using

instrument test in form of essay question from sevent indicators.The data analysis
used t-test, from the result of pretest calculation obtained the mean of experiment
class is about 32.56 with deviation standard 8.46 and the mean of control class is
about 31.16 with deviation standard 6.08. By testing the data both classes are
distributed normally and homogeny, with t count lower than t table (0.06 ttable it means Ha accepted. By
using t-test two tail seven indicators were tested. The result shows science process
skill in problem based learning significantly higher than control class. By the
other words it can be concluded that there is effect of problem based learning on
students’ science process skill and learning outcomes at human excretory system
topic in grade XI SMA Negeri 5 Binjai Academic Year 2014/2015.
Keywords: Problem Based Learning Model, Conventional Learning, Science
Process Skill, Learning Outcome.
