Received: September 9, 2019 Revised: December 18, 2019 Accepted: April 11, 2020 Abstract Dust is one type of potential hazardzs in the workplace that can affect the health of the workers. The occupation that are always exposed to dust is furniture industry workers so that they have higher risk of getting acute respiratory tract infection (ARI) disorder which can interfere with breathing. The wood dust is formed from some of the sawn wood and sanding that will lead to an acute respiratory tract infection. The study aimed to determine the effect of environmental factor and the use of Personal Protective Equipment (PPE) against the symptoms of acute respiratory infections in the furniture industry workers. The research method used was quantitative method with observational and cross-sectional research types and it was analysed by using logistic regression test. The population in this study was the workers of the furniture industry at Semarang street. Surabaya City, with a total of 57 people, of which 37 furniture workers as a The results show that most of the workers has symptoms of acute respiratory tract infection. It could be influenced by the environmental factor such as dust exposure that produced wood dust in each manufacturing Additionally, the use of PPE also affected the occurrence of acute respiratory tract infections symptoms in the workers. In conslusion, many factors can influence the occurrence of acute respiratory tract infection symptoms in the furniture industry workers. Therefore, it is necessary to minimize the dust exposure in workers by wearing PPE such as respirators. Keywords Environmental factor, personal protective equipment, dust, acute respiratory tract infection symptoms INTRODUCTION conditions can be caused by unsafe actions Occupational illness is any disease and conditions. One of the unsafe conditions contracted primarily as a result of an in the environment is the presence of dust exposure to risk factors arising from work hazards in the workplace.

Meanwhile, an acute respiratory tract infection (ARI) is a major health packing, blasting from objects, both organic problem in Indonesia, with the prevalence of and inorganic, which have a diameter such disease is as much as 25. 5%, where 16 1 AAm to 500 AAm . There are provinces of which have a prevalence above several types of dust namely coal dust, the national rate. Acute respiratory tract cement, cotton, asbestos, wood dust, dust infections rank first out of the 10 most during the rice milling process or organic diseases suffered by people in Indonesia. The dust and others. results of RISKESDAS of Indonesia (Basic workplace can cause acute or chronic Health Researc. in 2013 showed that the respiratory distress in the workers. Various factors affect the onset of such disease. Those infections was 24%. In addition, pneumonia factors include dust particles size and shape, also becomes the health problem in Indonesia dust concentration, dust chemical properties which is as much as 2. and duration of dust exposure.

The factors that affect a The physical process of the raw materials of person's risk of Acute respiratory tract the furniture manufacture tends to produce pollution such as wood dust particles. Approximately, 10 to 13% of the sawn wood One and sanding will produce wood dust. This environmental factors is air pollution in the wood dust can generate particle pollution in workplace while the individual factors includ the air and environment. In addition, the age, gender and education level which can wood furniture industry workers can be affect the risk of susceptibility to Acute exposed to dust .

MATERIALS AND METHODS This research method was a quantitative RESULTS research using observational research types Distribution of Acute Respiratory Tract and cross-sectional approach. This research Infection Symptoms was carried out in Semarang street. Surabaya Based on the results regarding the City. East Java. The population in this study distribution of workers who experienced ARI were the workers in the furniture industry in symptoms are shown in Table 1. Table 1.

Exposure to dust can cause either acute infections symptoms compared to those who or chronic respiratory health problems. Dust use personal protective equipment. particles that can cause acute respiratory problems are industrial products that can pollute the air such as wood dust, coal. DISCUSSION Symptoms of Acute Respiratory Infection ARI is an acute inflammation of the above and below respiratory tract due to microbial or bacterial, viral, and rickets or accompanied by inflammation of the lung parenchyma . ARI . cute or lower respiratory tract diseas. WHO, contagious which can then cause a variety of infections to severe deadly diseases . ARI is an infectious disease that attacks one part and or more of the airways, starting from the nose . cute channe. to the alveoli . ower channe. including related tissues, such as sinus, middle ear cavity and pleura . There are several factors that can influence a person's risk of getting ARI, such Environmental factors include air pollution that can be generated from industrial product. Meanwhile, individual factors affecting ARI are age, sex and education level. Lastly, the cement, asbestos, chemicals, and the others. There are several factors that influence the emergence of diseases or disorders of the respiratory tract due to dust. These factors are dust particles, dust shape, concentration of dust, dust solubility and dust chemical properties as well as duration of dust Whereas, the individual factors include defense mechanisms or lung strength, anatomy and physiology of the respiratory tract . Based on the results of this research, the infections was 24 out of 37 correspondent. represents 65% of the workers. It can be concluded that the majority of workers have ARI. Acute infections have several symptoms, for example cough, flu, nasal congestion, sore throat, shortness of breath, fever, headache to muscle aches. However, many symptoms of acute respiratory tract infections were not examined properly. Many cases of ARI can cause complications, access to timely health Ina J Med Lab Sci Tech 2020. :42-49 Merry Sunaryo services will reduce the risk of disease particles of 0. 1-10 AAm, covering all sizes of severity and even death.
