Abstract: PT ABC Batam is a company that manufactures various kinds of fish fishing lures. The company's production

department always interacts with supporting equipment such as machinery, chemicals, and other equipment,

so good management of OHS is needed. To increase the awareness of workers and visitors from the risk of

danger, an induction safety video was made at PT ABC Batam. A video cannot be separated from the audio

that has the role of completing information or messages. For this reason, an analysis is needed to measure the

level of audience acceptance of the role of audio in conveying information, attracting the attention of the

audience, and inviting the audience to watch safety induction videos. The method used in the analysis is the

Quasi-Experimental type Experiment method with the Nonequivalent Control Group Design model. The

subjects of the study were 40 visitors to PT ABC Batam. The results showed the control group of

approximately 40% of the audience expressed disagreement for all questions presented and the experimental

group for more than 80% of the audience stated strongly agree for all questions presented. The results of

calculations between the control and experimental groups show an increased viewer acceptance of the role of

audio in a safety induction video so that Ha was accepted, which means that the audio's role was significant

in conveying information, attracting the attention of the audience, and inviting the audience to watch safety

induction videos.

1 INTRODUCTION

Work safety, health, and safety, or abbreviated as K3,

become the obligations and needs of companies in all

forms of work activities. A company must implement

K3 to create a workplace that is safe, efficient,

productive, and protected from work accidents.

PT ABC Batam is a company that manufactures

various kinds of fish fishing lures under the brand

name of PT ABC Batam. The production department

always interacts with supporting equipment such as

machinery, chemicals, and other equipment, so good

management of OHS is needed. To further increase

awareness and maintain the comfort of both workers

and visitors from dangerous risks, a safety induction

video was made at PT ABC Batam. An induction

safety video is a video that shows an exercise on

occupational safety and health aimed at visitors

visiting the company. The purpose of making this

safety induction video is to communicate the general

occupational safety and health hazards that exist

during the visit so that visitors who watch are aware

of and can take control of these hazards.

In making this safety induction video,

implementing sound/audio structuring in the form of

voice over, back sound, and sound effects are very

important to convey information, attract the attention

of the audience, and invite the audience to watch this

safety induction video. Good sound design is

expected to strengthen the mood or mood to be

achieved by a video (Effendy, 2009). Therefore, an

analysis is needed to measure the level of audience

approval of the role of audio in conveying

information, attracting the attention of the audience,

and inviting the audience to watch induction safety

videos.

This background encourages the need for

scientific research to evaluate how to make an

induction safety video of PT ABC Batam by

implementing sound management and measuring the

level of audience acceptance of the role of audio in a

safety induction video? To answer this research

question, the Quasi-Experimental type experimental

method is used with the Nonequivalent Control Group

Design model. This study aims to implement sound

management in PT ABC Batam's induction safety

2 LITERATURE REVIEW

Safety induction is the introduction of the basics

regarding occupational safety and occupational

health (K3) to new employees or visitors who want to

enter the company's area. This is done so that visitors

understand the company's existing conditions and are

required to comply with all applicable regulations

(Safety Shoes Website, 2019).

The video comes from Latin, video-vidivisum

means to see (has the power of vision); can see

(Kamus Besar Bahasa Indonesia, 2019). Video is a

merging of images per frame so that the screen looks

alive. Video has a function to present information,

explain complex concepts, explain the process, teach

skills, shorten or extend time, and influence attitudes

(Aryad, 2011). So, an induction safety video is a

video that contains a simulation of the introduction of

the company's environment and control of hazards

associated with K3 management, which is addressed

to visitors who are visiting.

A video cannot be separated from the audio that

has the role of completing information or messages.

Audio is a visual aid that can be heard (Kamus Besar

Bahasa Indonesia, 2019). Audio can be interpreted as

a medium for conveying messages in the form of

auditive symbols, both verbal (into words or spoken

language) and non-verbal (Sadiman, et al., 2009). So,

audio is an intermediary used to convey information

through the sense of hearing. The audio used in

making this safety induction video is in the form of

voice over, back sound, and sound effects.

2.1 Voice over

Voice over is a sound production technique by

reading texts by voice talent to deliver messages

(Indovoiceover, 2018). Voice over is also interpreted

as an additional narration in the form of a human

voice that reads a narration related to the video made.

Voice over in the media acts as a messenger can

function as informative or entertaining. Voice over

will be based on narration or script that is made by

adjusting the picture or video (Fachruddin, 2012). A

good script will help the process of delivering a

message.

Figure 1: Safety induction of PT ABC Batam.

2.2 Back Sound

Back sound is a background noise that adds to the

impression of an emotional atmosphere that is built.

For example, the impression that is built like,

cheerful, sad, tense, then the back sound played must

also be following the impression that was built. Back

sound can be a message encoding that can give rise to

certain meanings (Alex, 2009). With the back sound,

the visual message in the video will be more

prominent and easier to understand. If you use

someone else's song as a back sound, you must first

obtain permission from the song owner to avoid

2.3 Sound Effect (FX)

Sound effects are artificial or actual sounds that

display the power of imagination and interpretation of

experiences about the situation being displayed

(Sungkono, 1999). In general, sound effects that are

used must support the atmosphere you want to show

on the video, can use the original sound from the

video recorded by the camera, or use other sounds

that have been done in the editing process.

3 METHODS

3.1 Design Method

In designing this safety induction video, the Luther-

Sutopo method is used to produce multimedia

products systematically. The stages of designing the

Luther-Sutopo method are presented in detail in

Figure 2.

Analysis of Sound Editing in Safety Induction Video at PT ABC Batam

Figure 2: Design phases of Luther-Sutopo.

The Luther-Sutopo multimedia development

methodology consists of 6 (six) stages, namely

concept (concept), design (design), material

collection (material collecting), manufacture

(assembly), testing (testing) and distribution

(distribution) (Binanto, 2015). The use of the Luther-

Sutopo method can produce products that are

programmed to solve problems with research needs

(Saputro, 2019).

3.2 Data Collection Technique

Data such as activities, behavior, place or location

and objects, image recording, as well as PT ABC

Batam's Standard Operating Procedure (SOP)

guidelines are needed in making this induction safety

video. Data collection was obtained using the method

of observation, documentation, and questionnaires

for the testing phase.

3.3 Research Methods

The research method is a method used by researchers

in gathering research data (Arikunto, 2002). This

study using a mixed research method (Mixed

method). Mixed research is a method by combining

two studies, namely qualitative and quantitative.

Qualitative data in the form of criticisms and

suggestions put forward by media experts to improve

audio in alpha test. Quantitative analysis techniques

in this study used descriptive statistical analysis in the

form of a questionnaire with a Likert scale on the beta

test.

Alpha Test: Testing by media experts as

audio assessors on this induction safety

video. The aim is to test whether the audio

used can be accepted by the audience and is

worth listening to in terms of audio quality.

Beta Test: This test is done by giving video

with/without audio to the audience so that

they can measure the level of audience

acceptance of the role of audio in a safety

induction video. To test the beta test using

Quasi-Experimental research with the

Nonequivalent Control Group Design model.

To obtain data in conducting research, we need a

tool or instrument in the form of a questionnaire. In

general, the scoring technique used in the research

questionnaire was a Likert scale technique. The

questionnaire in the form of a link was distributed to

40 visitors as respondents. To answer the questions

on the questionnaire, respondents will use 5 scale

choices namely, Strongly Disagree, Disagree,

Neutral, Agree, and Strongly Agree.

To get the results of interpretation of the valuation

items the following formula is used.

X = lowest Likert score*number of participants

Y = highest Likert score*number of

participants

Evaluation of respondents' interpretations is the result

of the value generated using the% index formula.

Index % = Total of score/Y * 100 (1)

After the index percentage is obtained, the results

are matched with the interval scores above. Then the

results will show what categories are produced

(Darmadi, 2011). T-tests are needed to determine the

significance of differences in test results between the

control group and the experimental group (Suprapto,

2013).

3.4 Hypothesis

The hypothesis comes from the words hypo and

thesis. Hypo means less than, while the thesis means

opinion. So, the hypothesis is in the form of an

opinion or conclusion from the problem under study

which is still temporary (Margono, 2004). A

hypothesis is a temporary assumption or conjecture

regarding something that is made to explain

something that is often required to check (Sudjana,

2005).

Based on the explanation above, the hypothesis is

the significant role of audio in conveying

information, attracting the attention of the audience,

and inviting the audience to watch safety induction

videos.

4 RESULTS AND DISCUSSION

This research produces 1) a safety induction video by

implementing sound management in the form of

voice over, back sound, and sound effects, 2) the

results of the measurement of the level of audience

acceptance of the role of audio in a safety induction

video. Results and discussion include alpha test

results and beta test results.

4.1 Results of Alpha Test

After testing by media experts with alpha test testing,

the test results have been obtained as in Table 1.

Based on the results of tests that have been done, the

average media expert answers with a scale of answers

4 (agree) and 5 (strongly agree). Then it can be

concluded that audio is feasible to use.

4.2 Results of Beta Test

5 CONCLUSIONS

Based on the research conducted, the following

conclusions are formulated:

By producing a safety induction video and

implementing sound management in the video,

it can communicate the general occupational

safety and health hazards that are present during

the visit, so that visitors who watch are aware

and can take actions to control the danger

because they are invited to see indirectly

simulations and conditions real area to be

visited. The video is designed using the Luther-

Sutopo method which consists of 6 stages,

namely concept, design, material collecting,

assembly, testing, and distribution.

Before being given treatment the level of

audience acceptance of the safety induction

video has an average value of 28.75. After being

given treatment in the form of additional audio,

namely, voice-over, back sound, and sound

effects, the level of audience reception increased

to 43.85. The test was successful following Ha,

which means the significant audio role in

conveying information, attracting the attention

of the audience, and inviting the audience to

watch safety induction video.
