PROBLEM SOLVING ABILITIES USING
PROBLEM BASED LEARNING AND PROBLEM
SOLVING LEARNING MODELS IN THE
MATERIAL OF THE BASIC LAWS OF
CHEMISTRY AT SMAT WIRA BHAKTI
2. introduction
The 2013 curriculum is set as an effort to improve the quality of Indonesia at
every level assessed from three domains competencies, namely: knowledge,
attitudes, and skills.
Based on the PISA survey results in 2018, there are components of students'
problem-solving skills which show that 70% of students in Indonesia are not
able to reach level 2 inframework PISA, even though on average only about
23% of students from 79 countries who are unable to master level 2 reading
skills, therefore, This shows that the literacy of Indonesian students, which
includes problem solving skills are still very low (Hidayatulloh et al., 2020).
Problem solving ability is a very important factor and must be achieved by
students in learning activities that are abstract and mathematical.

Problem based learning & Problem solving
Problem solving ability
21st century learning requires students to have several
abilities, one of which is problem-solving skills which are
criteria for learning and innovation abilities (Maemanah et
al., 2019). Critical thinking skills are skills to perform
analysis, assessment, evaluation, reconstruction, and
decision making that can lead to rational and logical
actions. Thinking activities about subjects, content and
problems are carried out through analysis, assessment
and reconstruction activities (Redhana, 2019).
5. Problem solving
Problem based learning & Problem solving
Problem based learning
PBL (Problem based learning) is a learning model that
greatly optimizes students' thinking skills through a
systematic group work process, enabling students to
continuously improve, improve, develop and test their
thinking skills (Ilmiyatni et al., 2019).
6. Problem solving
Problem based learning & Problem solving
Problem solving
problem solving learning model or solving which is in
accordance with the name problem solving learning is a
learning model that requires students to solve problems
according to the field of science being studied which aims
to train students to think critically so as to increase student
understanding and produce good quality learning.

8. RESULT AND
D I S C U S S I O N
Data obtained from this study is quantitative data, this quantitative data is used to
compare students' problem solving skills between classes that use problem based
learning models and classes that use problem solving. The experimental class I is
class X IPA 2 which applies the problem based learning and the experimental class II is
X IPA 3 which applies the problem solving. The data analyzed were data obtained from
the pretest and posttest of students on the material of the basic laws of chemistry. The
number of students involved in this study consisted of 40 students from class X IPA 2
and class X IPA 3 at SMA Terpadu Wira Bhakti. Based on the post-test in the
experimental class I (problem based learning), the average problem solving ability of
students was 83 and for the experimental class II (problem solving) the average
problem solving ability of students was 71.
9. D I S C U S S I O N
This shows that the learning process on the basic laws of chemistry by
applying problem based learning and problem solving can improve
students' ability to solve problems in problems, however, there is a
difference that using problem based learning can further increase
posttest students'. By applying the problem-based learning can improve
students' problem-solving abilities effectively (Putri Ulva Amalia and
Wahyudi, 2020).
10. CONCLUSSION
Based on the results of the study, the average posttest of students in the
class that applied the problem based learning was higher, namely 83 and the
class that applied the problem solving was 71.09, then the data were
analyzed using t test so that thecalculated 4.9774 and the ttable at level = 0.05; dk
= 38 obtained by 1.68595. Thus, tcount is seen as greater than ttable (tcount =
4.9774 ttable = 1.68595) so that H0 is rejected, meaning that H1 accepted. So it
can be concluded that this research hypothesis is proven, namely that there
is a significant difference between students' problem solving abilities on the
subject of basic laws of chemistry between classes that apply problem
based learning and classes that apply problem solving at SMA Terpadu Wira
Bhakti.
