This study aims to describe the critical thinking skills of
junior high school students on the subject of the Human
Circulatory System in Situbondo Regency. This type of
research is descriptive quantitative by using critical
thinking test questions. The number of respondents in this
study amounted to 236 students in 5 schools in Situbondo
Regency. The critical thinking test questions on the
material of the human circulatory system are in the form
of multiple choices and consist of five questions according
to the critical thinking indicators according to Ennis. The
results of the critical thinking test of junior high school
students in Situbondo Regency with the material of the
human circulatory system showed an average score of
47%, for the indicator of the ability to provide simple
explanations an average of 54%, the indicator of ability to
build basic skills an average of 48%, the indicator of ability
to conclude an average of 48%, the indicator of ability to
provide further explanation an average of 49%, and the
indicator of ability to set strategy and tactics an average
of 37%.

INTRODUCTION
The development of science and technology today changes all aspects of human
life. This condition has a great influence in all fields, one of which is education (Wijaya,
Sudjimat, Nyoto, & Malang, 2016). In the 21st century, the challenge in the field of
education is to improve the quality of Human Resources (HR) so that humans are able to
compete globally (Lestari, 2014). Improving the quality of human resources through
education is focused on higher order thinking skills (HOTS) (Abosalem, 2016). HOTS is
one of the skills needed to prepare graduates who are able to compete and adapt to
changing times. Critical thinking ability is one manifestation of HOTS.
Based on the Regulation of the Minister of National Education Number 22 of
2006, it is stated that the scope of learning in the science and technology subject group is
intended to acquire advanced competence in science and technology as well as cultivate
scientific thinking critically, creatively and independently. Therefore, in learning,
students need to be equipped with critical thinking skills that can be used to analyze and
solve problems they will face in everyday life, one of which is in science learning
(Agustyaningrum, 2015).
The ability to think critically is an important thing, but the reality on the ground
is not as expected (Liberna, 2015). The critical thinking ability of junior high school
students in Indonesia is still relatively low. This is based on the four-year International
Trends in International Mathematics and Science Study (TIMSS) study conducted on
junior high school students with the characteristics of high-cognitive level questions that
can measure students' critical thinking skills, showing that Indonesian students
consistently fall in the lower ranks.
TIMSS is an international assessment of mathematics and science in grades 4 and
8 that has been and is still being held since 1995. In general, TIMSS aims to monitor
educational system outcomes related to student achievement in Mathematics and Science
(Mahmuzah, 2015). Indonesia is one of the countries that became the object of TIMSS in
the last four periods. Talking about scientific achievements, Indonesia's position is still
below the international level, as reported by TIMSS. The results of the 2003 TIMSS
study, Indonesia is ranked 35 out of 46 participating countries with an average score of
411, while the international average score is 467. The results of the 2007 TIMSS study,
Indonesia is ranked 36 out of 49 participating countries with an average score of 397, the
results of the 2011 TIMSS study, Indonesia is ranked 38 out of 42 participating countries
with an average score of 386, while the international average score is 500. The latest
results, namely TIMSS 2015 Indonesia is ranked 44th out of 49 countries (Noordyana,
2016).
Critical thinking is the ability to analyze and evaluate information obtained from
observations, experience, reasoning and communication to decide whether the
information can be trusted so that it can provide rational and correct conclusions. Critical
thinking skills require high-level reasoning, namely high logical thinking. High logical
thinking is needed by students (Savitri, 2013). This is done especially in answering
questions, because students need to use their knowledge, understanding, and skills and
relate them to new situations (Ratnasari & Widjajanti, 2015). Students can think critically
if they are involved in creative thinking on the information obtained (Roets & Maritz,
2017). Students' critical thinking ability can be described with 5 indicators according to

Ennis, including the following; provide simple explanations, build basic skills, conclude,
provide further explanations, set strategies and tactics.
Based on the description that has been described, it is necessary to conduct
research on the profile of the critical thinking ability of junior high school students in
Situbondo on the material of the human circulatory system that is able to describe the
critical thinking ability of junior high school students in Situbondo. In accordance with
the Regulation of the Minister of National Education Number 22 of 2006 it is stated that
the scope of learning in the science and technology subject group is intended to acquire
advanced competence in science and technology as well as cultivate scientific thinking
critically, creatively and independently. Therefore, in learning students need to be
equipped with critical thinking skills that can be used to analyze and solve problems they
will face in everyday life, one of which is in learning Natural Sciences. knowing the
profile of the critical thinking ability of junior high school students in Situbondo
Regency.
RESEARCH METHOD
The type of research used in this research is descriptive research with a
quantitative approach. Thus, this study discusses the critical thinking skills of junior high
school students in Situbondo Regency in solving problems of the human circulatory
system. The research subjects were students of class IX SMP in Situbondo Regency
2021/2022 a total of 236 students from 5 schools in Situbondo Regency. Data on critical
thinking skills were obtained through a research instrument, namely a critical thinking
ability test consisting of multiple choice questions developed from five indicators of
critical thinking ability according to Ennis.
This research begins by looking for valid critical thinking questions about the
material of the human circulatory system. After that, make the test in the form of a
Google Form so that respondents can do it online. The next step is to distribute critical
thinking tests to grade IX students in 5 schools in Situbondo Regency. After the data is
collected, the next step is to analyze it using descriptive analysis techniques in the form of
calculating the overall average of students' critical thinking abilities and calculating the
average of students' critical thinking abilities for each indicator.
To present the score of each indicator of critical thinking ability which is assessed
using equation:

Information:
Cs = Percentage of students' critical thinking skills
C = Total scores obtained by students
N = Total score
The percentage of critical thinking skills obtained by students as a whole and
each indicator, then grouped based on the criteria for critical thinking skills below [21].
