Abstract. Decreasing of the learning concentration was defined as a decreasing ability to concentrate on
learning activity which was reflected through one's behavior (Ahmadi Abu, 2003). This condition affects a
person's understanding. This study aimed to analyze the effect of time, types of subject and types of room
factor to the decrease of students’ concentration in learning and analyze the maximum point of the students to
concentrate in learning and propose ergonomic systems (GWM H02C05 room and H02A07 room,
Department of Industrial Engineering, Maranatha Christian University, Bandung).
Data that were collected in this study were Visual Analogue Scale, Group Bourdon Test and field observations
with 48 total respondents. The further observations were processed using ANOVA test with between-subjects
design (3-ways interaction)
ANOVA test results showed that the time factor and the types of subject factor affected to the learning
concentration of students. Types of room factor did not affect to the learning concentration of students. The
result of Visual Analogue Scale, Group Bourdon Test and observations gave the same result, that learning
concentration of the students was decreased. The proposals that could be given were doing a good course
scheduling such as mathematical subject should be placed in the morning time (at 07.00 am - 11.00 am) and
theoretical subjects placed on the day time (at 11.00 am - 03:00 pm).
Keywords: time, types of subject, types of room factor, VAS, Group Bourdon Test
1. INTRODUCTION
If the decrease of the learning concentration was
further reviewed, it would lead to misunderstanding and
ignorance about the learning materials, which was
essentially a student must know and understand the
learning material provided by an institution, so that there
will be a change in behavior in the learning process that
exist (Moh. Surya, 1977). Thus, it could be said that the
level of understanding in learning was affected by the
learning concentration. If there was a decrease in the
learning concentration, then there was a decrease in the
ability to concentrate on learning activities (Ahmadi Abu,
2003). This condition was reflected from each of the
behavior which is an indicator of a persons’ psychological.
The decrease of the students’ learning concentration was
affected by various factors, including the time, type of
subject and type of room factor.
Researchers determined the initial hypothesis based on
the results of preliminary processing of the data
questionnaire that had been distributed by the researchers to
the students and also the results of the interviews conducted
by researchers introduction. Thus, the following hypothesis

3. DATA COLLECTION
Data collecting for the Visual Analogue Scale (VAS)
was a data collecting carried out by the researcher to
obtained students’ concentration conditions in a
subjectively manner because measuring the perceived level
of concentration of an individual at the time.
Visual Analogue Scale (VAS) is a measurement
instrument that tries to measure a characteristic or attitude
that is believed to range across a continuum of values and
cannot easily be directly measured. For example, the
amount of pain that a patient feels ranges across a
continuum from none to an extreme amount of pain.
Operationally a VAS is usually a horizontal line, 100 mm in
length, anchored by word descriptors at each end, as
illustrated in Figure 3. The VAS score is determined by
measuring in millimetres from the left hand end of the line
to the point that the patient marks. The visual analogue
scale (VAS) has been reported to be the most standardized,
valid and easy to comprehend self-report pain assessment
instrument. (Gould et al, 2002).
Group Bourdon Test is a train driver concentration test.
It is also knows as dot cancellation test. This test based
train driver psychometric used to maintain vigilance, speed,
accuracy, and concentration while looking a group of 4 dots.
Data collection for Group Bourdon Test is a data
collection conducted by researchers to obtain students’
concentration condition in a objectively manner, by
measuring objectively and calculating mathematically
about one’s concentration level.
Data Collecting in a subjectively-objectively manner
by :
a. Measurement of the respondents conducted by the
makers of observation data through behavior of the
respondents (subjective). Weighting on the indicator of
this research conducted individually by each
1 Eyes looked at the left side or right side (turning to the left or right)
2 Eyes looked at downward (head down or asleep)
3 Blank stare (eyes) or daydreaming
1 Pay attention to other things (attention to others conversation or to outside of classroom)
2 Concentration focused to an object

respondent due to the weight of one with the other
respondents will create different results.
b. Measurement of behavior of the respondents through
the key behavior (objective) shown in table 1.
Figure 2 illustrates a data collection scheme conducted by
researchers of the 48 respondents :
Before Treatment : Data collection was performed
outside the classroom before the lecture begins by
using initial Visual Analogue Scale (VAS) and initial
Group Bourdon Test.
During Treatment : Data collection was performed by
observations in the classroom. Initial benchmark of
this observation is the key behavior that have been
described previously (Table 1)
Post Treatment : Data collection was performed
outside the classroom after the lecture is finished by
using the Final Visual Analogue Scale (VAS), Final
Group Bourdon Test and weights of key behavior.
4. RESULT AND DISCUSSION
The overall condition of the concentration of
respondents (using the Visual Analogue Scale: subjective)
before treatment was higher than the post treated condition
as shown in figure 5. The overall condition of the
concentration of respondents (using the Group Bourdon
Test : objective) before treatment was higher than the post-
treated conditions as shown in figure 6. Table 2 showed the
results of the data collection which were performed by the
researchers could be concluded as an eligible data for
ANOVA test (the data is independent, normal distribution
and homogeneous). Table 3 showed the results of the
ANOVA test (used by researchers to answer the initial
research hypothesis 1 to hypothesis 7), it could be
concluded that there are only 2 factors that affected student
learning decreased concentration i.e. the time factor and
interaction between time and type of subject factor using
0.05.
This research found that from the three methods, i.e
Visual Analogue Scale (VAS) ratings, Group Bourdon Test
and ANOVA test, all had the same conclusion (Table 4).
The conclusion was there was an effect for students’
concentration (there was a significant decrease from
students’ learning concentration prior student learning
activities in the classroom to the students’ learning
concentration after learning activities in the classroom).
Descriptive statistics of test results (used by
researchers to answer the initial research hypothesis 8), it
showed that the maximum point required for students to
concentrate is between 0,750 first hours to 1,139 first hours
of their learning process, with a standard deviation 0,178
hours up to 0.643 hours.
So it could be concluded that the maximum point for
the students’ learning concentration required was
approximately 1 hour starting from the beginning of the
first lecture as shown in figure 7.
From the data processing and analysis result, therefore
it was suggested an ergonomic system to enhance the
student’s learning concentration as follow:
a. Allocating particular subjects on certain period
within student’s class time table such as
mathematical subjects should be placed in the
morning time (7.00 am – 11.00 am) and theoretical
subjects placed on the day time (11.00 am- 3.00
pm).
b. Notice the condition of the maximum point of
students in learning, approximately the first 1
hour lecture. Lecturer should be able to regain
students’ concentration by setting their tone up and
down during the lecture or designing games for
the lecture so that students are not bored or sleepy.
c. Changing the 3-credits-course (2 hours 30 minutes)
which only held in one class meeting, became two
classes meeting. (1 hour 40 minutes at the first
class meeting and 50 minutes at the second class
meeting).
d. Hence, for the 2-credits-course (1 hour 40 minutes)
would remain as it is, according to in accordance
with the conditions of the initial conditions of the
Industrial Engineering Department, Maranatha
Christian University.

5. CONCLUSION
From Visual Analogue Scale graphic and Group
Bourdon Test graphic, there was a significant decrease from
students’ learning concentration prior student learning
activities in the classroom to the students’ learning
concentration after learning activities in the classroom.
Based on Anova Testing and analysis result, it was found
the conclusion that there were 2 factors that affected the
students’ learning concentration decrease, which was a
factor of time (Factor A) and the interaction between the
time factor and the type of subject factor (AB Factor
Interactions). Based on descriptive statistics analysis,
students were still able to concentrate on studying for 1
hour (maximum 1,139 hours) in accordance with the initial
hypothesis of the study).
The recommendations that were given to the
Department of Industrial Engineering, Faculty of
Engineering, Maranatha Christian University, Bandung,
Indonesia such as allocating particular subjects on certain
period within student’s class time table; Lecturer should be
able to regain students’ concentration by setting their tone
up and down during the lecture or designing games for the
lecture so that students are not bored or sleepy; Changing
the 3-credits-course became two classes meeting.
