CHAPTER 4

REACTION TIME4.1. Practicum Purposes

1. Students are able to understand reaction time toward visual display.

2. Students are able to understand the concept of long-term and short-term

memory.

3. Students are able to analyze the long-term and short-term memory of person.

4. Have a capable to compare the reaction time toward stimulus of male and

female using hypothesis testing.

4.2. Practicum Assignment

1. Take the data using visual tools to determine the reaction time of operator,

then compare the results with the average students in one small classroom.

2. To test the difference by using SPSS to know there are differences on the

results obtained.

3. Take the data using chunk method to determine the short-term memory

capacity of operators, and then compare the results with the average students

in one small class of the opposite sex by using a graph.

4.3. Output

4.3.1. Description

In this practicum, observer would like to calculate the Recommended

Weight Limit to the operator which doing a Manual Material Handling,

which is lifting. The data below is the data of the main operator and the

activity which done by the operator that involved in this research.

c. Word Chunk Test


d. Figure Chunk Test

e. Visual Reaction Time Test

f. Auditory Reaction Time Test

In this practicum, the operator did some test such as visual test and chunk

test. In visual test, the operator record the test results using the reaction

speed measuring device, the operator was seeing colors and then pressing

the corresponding key tool of the same color and note how many times the

speed obtained by the operator. While chunk test is consist of some test

such as number chunk, letter chunk, word chunk, figure chunk, and color

chunk.

In number chunk test, the operator was given some number in a short

period. Letter chunk test was a test by give the operator some letter in a

short period. Word chunk test is a test by give the operator some word in a

short period then the operator have to write it down. Figure chunk test is a

test that was given to the operator in a short period, the operator should

remember all the picture and write it down. The last test is color chunk.

Color chunk test is test conducted that operator see a random color on short

period and write down the name of written color.

4.3.2. Data Collection

a. Visual and Auditory Data

Visual test is a test which is the operator was given state of seeing

colors and then pressing the corresponding key tool of the same color.

From the test that already did by the operator, the observer get the

result:

Chunk test is a test that consist of some test such as number chunk,

letter chunk, word chunk, figure chunk, and color chunk. In chunk test,

the operator was given some number, letter, word, figure and color in a

short period, the operator have to remember the numbers, letters,

words, figures and colors then take a note of the results. The result of

4.3.3. Data Processing

a. Visual Reaction Time Processing

To measure the comparison between visual reaction time processing

between female and male operator using independence sample t-test,

observer did the test of normality with 95% of significance level.

a. Lilliefors Significance Correction

Based on the table above, it can be seen that the significance value of

the data is reached >0.05, which means the data is normally distributed

and can be continued to T-test.

From the table 4.10, it can be seen that significance level is 0.016,

which is less than 0.05. Therefore, it is apparent that there is no

significance difference between female and male reaction.

b. Auditory Reaction Time Processing

Independence sample t-test is used to measure the comparison between

auditory reaction time processing between female and male operator,

observer use 95% of significance level.

a. Lilliefors Significance Correction

Based on the table above, it can be seen that the significance value of

the data is reached >0.05, which means the data is normally distributed

and can be continued to T-test.

From the table 4.13, it can be seen that significance level is 0.118,

which is less than 0.05. Therefore, it is apparent that there is a

significance difference between female and male reaction.
