Abstract: COVID-19 is a disease caused by the SARS-CoV 2 virus. Because this disease is transferred from person to
person, it is easily disseminated in crowded places like marketplaces. The Indonesian Ministry of Trade has
published health protocols for these market areas; therefore, implementing health protocols in the market is
one way to prevent COVID-19. This study aimed to identify factors associated with market traders'
compliance with health protocols. This study used a cross-sectional design with stratified sampling as the
sampling technique and 232 samples in total. A questionnaire was used for data collection. Binary logistic
regression was performed to test the factors associated with health protocol compliance. The findings revealed
that only 23.3% of respondents complied with health protocols. Knowledge (p = 0.001; OR = 0.06) and the
involvement of community leaders (p = 0.006; OR = 2.67) were statistically significant with health protocol
compliance among market traders. In conclusion, the majority of market traders were not in compliance with
health protocols. This result is related with knowledge, the role of community leaders, and respondents’
attitude; therefore, improving their knowledge and increasing the community leaders’ involvement are
necessary to strengthen health protocol compliance in the market.
1 INTRODUCTION
COVID-19 is a recently-identified coronavirus that
causes an infectious illness. Obtaining accurate
information about the COVID-19 virus is the greatest
approach to prevent and halt its spread. It is
recommended to avoid touching the face by washing
hands with soap or using alcohol-based products as
often as feasible. When an infected individual coughs
or sneeze, the COVID-19 virus spreads through saliva
droplets, meaning coughing etiquette is critical
(WHO, 2021). Indonesia is one of the countries with
the largest populations. Although it is in a relatively
warm place and the temperature is quite high, there is
still a need to be vigilant (Giarno, 2021). Positive
confirmed cases reached 106,834 in Bali, Indonesia,
from August 31, 2021 to August 31, 2022, with 3,508
deaths (Satgas Covid Bali, 2021).

Coughing, fever, and shortness of breath are
common COVID-19 symptoms. These signs and
symptoms are comparable to those of the flu in
general. However, in a tiny number of instances, no
respiratory symptoms such as diarrhea, nausea, or
vomiting are present. With symptomatic and
supportive care, most patients infected with COVID-
19 will recover in a few days. Serious symptoms such
as bronchitis and severe pneumonia can also occur in
some people (Paules et al., 2020).
Individuals infected with COVID-19 have
suffered from hypoxic respiratory failure in 19% of
cases, while 14% progressed to severe cases needing
oxygen treatment, and 5% required mechanical
ventilation and ICU hospitalization (Wu &
McGoogan, 2020). According to another study, 67%
of 52 COVID-19 patients with severe symptoms had
acute respiratory symptoms, 63.5% needed high-flow

oxygen tubes, 42% needed invasive mechanical
ventilation, and 52% needed non-invasive
mechanical ventilation (Yang et al., 2020). Some
individuals who had recovered from COVID-19 had
symptoms such as dyspnea, tiredness, cough, and
dysosmia that lasted longer (Miyazato et al., 2020).
Social distancing is one of the preventative
methods used to combat the spread of COVID-19.
Social distancing is a strategy for keeping sick
individuals apart from healthy people to decrease the
disease transmission risk. For example, canceling a
communal event or shutting down a public place, as
well as avoiding crowds (Pearce, 2020). To assist
COVID-19 transmission reduction, the Center for
Disease Control and Prevention (CDC) in the United
States suggests wearing a face mask in public if one
cannot keep a six-foot distance from others (CDC,
2021). Regular hand-cleaning with soap and water or
scrubbing with a hand sanitizer containing at least
60% alcohol is also necessary (Wimalawansa, 2020).
Although most healthcare professionals believe that
washing hands with hand sanitizer is fast, it is
ineffective and promotes dryness, according to a
study (Fatima et al., 2021).
Markets have traditionally been at the center of
city life. Markets continue to play an essential role in
the local food supply and regional economy, despite
the rise of commercial retail and internet shopping
(González, 2020). Markets are still in the spotlight in
many parts of the world when it comes to COVID-
related precautions. The market's crowded, open, and
public natures are thought to be the greatest danger of
uncontrolled virus transmission (Munster et al.,
2018). The COVID-19 pandemic has had a
significant impact on the income of traditional market
traders in Indonesia. The variable of trading hours
affects the traders’ income due to the social restriction
policies (PPKM), which limited the operating hours
for trading (Lathief Ilhamy Nasution, 2022).
The Indonesian Ministry of Trade published
Circular Letter Number 12 of 2020, which governs
the restoration of commercial activities disrupted by
the COVID-19 pandemic. The market area, also
known as traditional marketplaces, is one of the
places where commercial activities are being
recovered. When functioning, markets that sell items
for the community's fundamental requirements must
follow rigorous health protocols consisting of 11
principles to be followed by all market visitors,
including traders (Kemendag RI, 2020).
Until an effective and safe vaccine is developed,
community cooperation with health protocols is
essential in COVID-19 prevention. Because
compliance with preventative activities such as health
protocols is still lacking, changes to the community’s
behavior are needed(Ranjan et al., 2020). In a study
of public transportation facilities, it was discovered
that social distancing regulations were followed,
although mask usage still needed strict supervision
(Komla et al., 2020).
A study has confirmed that efforts to limit the
spread of human viruses to humans must be done
(Mege et al., 2020). There is a high risk of spreading
COVID-19 in the market area despite the health
protocols that have been implemented. Hence, the
objective of this study is to identify the factors
associated with market traders' health protocol
compliance; by knowing the related factors, the
spread of COVID-19 can be prevented.
2 MATERIAL AND METHODS
A cross sectional study was conducted on market
traders in four markets in Tabanan City, Bali,
Indonesia. Using the stratified sampling technique,
the sample size for this study was 232 respondents
consisting of market traders in four marketplaces in
Tabanan City. Simple random sampling was used to
choose respondents from each market, resulting in a
total of 58 respondents from each market based on the
proportions.
Traders in four traditional marketplaces in
Tabanan City who were still selling throughout the
COVID-19 pandemic and were willing to become
respondents by signing the informed consent form
were included in the study. Traders who did not have
reading skills, traders who agreed to participate but
did not finish the questionnaire, and traders who were
not actively trading during the COVID-19 pandemic
were all excluded.
A questionnaire was utilized as the research
instrument. The questionnaire was divided into three
sections. Part 1 comprised questions designed to
identify respondents' general characteristics, part 2
contained questions on following health protocols,
while part 3 had questions about variables that
affected following health protocols. An ordinal scale
was utilized in this study.
Prior to data collection, permission was requested.
The National Unity and Political Agency of Tabanan
Regency granted authorization for this study via letter
number 071/379/BKBP/2021, which was
subsequently dispositioned to the Tabanan Regency
Department of Industry and Trade. The Research
Ethics Commission of Bali Institute of Technology
and Health also gave its approval to this study, with
letter number 04.0341/KEPITEKES-BALI/IV/2021.

The data collection process was then resumed with
the delivery of questionnaires to respondents directly.
The questionnaire data were double-checked to
ensure that it was comprehensive.
The Statistical Package for Social Sciences
(SPSS) version 25 was used for data entry and
analysis. The frequency distribution and proportion of
each independent variable were determined using
univariate analysis. The chi-square test was used to
evaluate the components that were associated with
compliance in a bivariate study. The factors were
deemed related if the p-value was less than 0.05 (p <
0.05). To find the factors that were strongly related to
health protocol compliance, a multivariate analysis
using binary logistic regression was conducted based
on OR number, CI percentage, and p-value.

4 DISCUSSION
The results of the study found that 23.3% of market
traders in the traditional Tabanan City market were
compliant. A study by Komla (2020) found an
identical result with public transportation. The policy
on social distancing was abided by public
transportation users, however, the policy on mask use
still required careful supervision (Munster et al.,
2018). A study by González (2020) found that
preventive practices such as health protocols were
related to the progression of COVID-19, and
compliance with these practices was still
unsatisfactory (González, 2020). Compliance with
health protocols, especially in the market sector, was
poor, as evidenced by study results showing most
market traders did not follow health protocol
implementation effectively. Knowledge regarding
COVID-19 and the involvement of community
leaders in health protocol implementation were
shown to be variables associated with compliance in
this study.
Knowledge about COVID-19 and health
protocols, perception of COVID-19, the role of
community leaders, attitude toward health protocol
policies, and media access regarding COVID-19 were
the factors investigated regarding health protocol
compliance. Table 2 shows that three components
were found to be associated in the bivariate analysis
using the chi-square test, namely knowledge, the role
of community leaders, and attitude. COVID-19 was
well-known among the majority of respondents
(92.2%). COVID-19 was viewed positively by the
majority of respondents (74.1%). The proportion of
positive and negative views on the role of community
leaders was equal (50%). The majority of those polled
had a negative view of health protocol policies
(79.3%). The majority of traders had limited access to
information on COVID-19 (58.2%).
According to the results of the multivariate
analysis, there were two characteristics associated
with compliance with health protocols: knowledge
and the involvement of community leaders. Table 3
shows that knowledge regarding COVID-19 and
health protocols had an OR value of 0.06; thus, a 1-
OR formula was required to draw conclusions, and 1
- 0.06 = 0.94 was achieved. This led to the conclusion
that traders with strong knowledge of 0.94 times or
94% had a decreased chance of following health
protocols (OR = 0.06; 95% CI = 0.02 0.20; p =
0.001). Because the role of community leaders had an
OR of 2.67, traders who had a positive view of their
function were 2.67 times more likely to follow health
protocols than traders who had a negative view (OR
= 2.67; 95% CI = 1,328 – 5,356; p = 0.006).
On the knowledge aspect, this study discovered
that most market traders (92.2%) had a solid
understanding of COVID-19, and that this knowledge
was highly connected to market traders' compliance
with health protocols. Market traders, on the other
hand, were linked to a lack of attention to health
protocols. Hossain (2020) investigated the
relationship between knowledge and attitudes with
health protocols in adult respondents in Bangladesh,
claiming that adequate knowledge about COVID-19
and health protocols was needed to create behaviors
to prevent COVID-19 transmission (Hossain et al.,
2020). According to a study conducted on a group of
primary children in Wuhan, China, awareness of hand
cleanliness and the use of masks was extremely
helpful in reducing infectious illnesses (Chen et al.,
2020). However, in this study, having a strong
understanding of COVID-19 was not enough to get
market traders to follow health protocols. One of the
causes of ignorance to the introduction of new rules
might be markets that are identical to free or informal
settings. More qualitative in-depth studies on the
connection between COVID-19 knowledge and
compliance with health protocols is needed.

23
The importance of community leaders in ensuring
that health protocols were followed was also a key
issue. The function of community leaders was
evaluated from market traders’ perspective. The
majority of market traders who had a negative view
of community leaders’ roles did not follow health
protocols, according to this study. Rosidin (2020) has
mentioned that the forms of support provided by
community leaders were divided into emotional
support, appreciation support, instrumental support,
and informative support. Empathy, care, and concern
are examples of emotional support. Expressions of
respect and encouragement to continue forward are
examples of appreciation support. Instrumental
support includes direct help tailored to the
community’s needs. Advice, hints, suggestions, and
feedback are all examples of informative help. During
the COVID-19 pandemic, this type of assistance is
required (Rosidin et al., 2020).
Wright (2020) states that local governments also
have an important role in overcoming the impact of
COVID-19 (Wright, 2020). Market administrators,
which include coordinators, deputy coordinators, and
market collectors, are the closest community leaders
in the market. They are responsible for overseeing
and coordinating with their particular target market
regions. In addition, security officers known as
pecalang are stationed throughout Bali. Puspawati
(2020) argues that during the COVID-19 pandemic,
pecalang were assigned as COVID-19 mutual
cooperation task forces, with one of their assignments
being supervising health protocols (Puspawati et al.,
2020). Meanwhile, Auliya & Arif (2021) state that the
role of the Department of Industry and Trade under
the Indonesian Ministry of Trade also needs to be
increased during the COVID-19 pandemic (Auliya &
Arif, 2021). One of these roles is that of a facilitator,
who provides help, facilities, and educational support,
which in this case includes health protocols. As a
result, increased supervision from local community
leaders is required for health protocol
implementation.
5 CONCLUSION
The results of this study showed that traditional
market traders’ compliance with health protocols in
Tabanan City during the COVID-19 pandemic was
poor. This was found to be related to the market
traders' knowledge of COVID-19. Although these
market traders had good knowledge about COVID-
19, it was not enough to make them comply with
health protocols; therefore, further research is needed
on other factors that affect COVID-19 knowledge and
health protocol adherence. The involvement of
community leaders in the market's health protocol
application also needs attention. Increased
supervision of health protocol application is
suggested to market community leaders.
