<![CDATA[Introduction: Lecturers are workers who are actively involved in educational, research and community service activities at a college. Many duties and responsibilities of lecturers in their work can cause fatigue which is the body's response as a defense mechanism when the work exceeds its capacity. Different capacities can be assessed based on gender which also allows differences in response to the problem. The inability to cope with a problem or job produces a feeling of depression which can also be called as stress. The purpose of this study was to analyze the correlation between gender and work stress with fatigue at a faculty lecturers at a university in Surabaya. Method: This research was an analytical descriptive study in a faculty lecturers at a university in Surabaya. The study design was cross-sectional. Data were obtained through the results of a questionnaire distributed to lecturers who have met the criteria, as many as 43 respondents. Results: The study showed that 16 female respondents (57.2%) experienced moderate fatigue. About 19 respondents (63.3%) had mild stress and experienced mild fatigue. The correlation value between gender and fatigue was 0.816 and the strong correlation between work stress and fatigue was 0.000. This value indicated that there was no correlation between gender and fatigue, but there was a strong and direct correlation between work stress and fatigue. Conclusion: The occurrence of fatigue is not influenced by gender and high fatigue can be influenced by the high work stress felt by them.Keywords:fatigue, gender, lecturer, work stress ]]>

<![CDATA[ Introduction: One of the hazards caused by the process of producing plastic sacks is noise. Noise is unwanted sound judged to be unpleasant, loud or disruptive to hearing. Noise is produced by machines used in the production process. Noise that exceeds the threshold limit value (TLV) at workplace can cause hearing loss. The purpose of this study was to analyze the hearing threshold level of workers who were exposed to noise in circulator loom unit at PT. Kerta Rajasa Raya Sidoarjo. Method: This was an observational study with a cross sectional approach. The population of this study was 47 workers, while the sample was the total population. The independent variable wasnoise, while the dependent variable was the hearing threshold level. Contingency coefficient was used to detemine the strength of correlation between variables. Noise intensity measurement at three points revealed that the value exceeded the time limit value. Result: Most of the workers were > 40 years old (72.3%), had work period of 15-20 years (51.07%) and never consumed ototoxic medication (80.85%). Conclusion: A moderate correlation between the noise intensity and hearing threshold level of right ear. However, the correlation between noise intensity and hearing threshold level of left ear is weak. Keywords: hearing threshold level, noise, work characteristic]]>

<![CDATA[Introduction: Fertilizer companies are companies that use large amounts of chemicals, natural gas as raw equipment and assist in the production process, as well as the use of factory equipment with high temperatures and pressures, making companies with high levels of risk. The purpose of this study is to determine the general picture of physical and chemical factors in the work environment and the risks that can occur to workers and companies in fertilizer companies in Indonesia. Methods: This research was conducted using descriptive methods, the object observed in this study is the physical and chemical factors that exist in fertilizer companies. Results : Lighting intensity in all areas of the operational departments of fertilizer companies in Indonesia is only 12%, which is in accordance with the Threshold Limitation Value (TLV). Intensity of noise in the area of the company, as much as 17% is above the Threshold Limitation Value (TLV). The level of dust in this fertilizer company is 33% of the area that exceeds the Threshold Limitation Value (TLV). These three things can increase the risk to health, even increase the intelligence of the workers themselves. In addition to the risks to the workers, these three things can also benefit a company's productivity. Conclusion: All areas of fertilizer companies have risks originating from physical and chemical factors. So it needs to be carried out appropriate control in order to reduce the risks that can occur both for workers and companies.Keywords : dust, ferilizer plant, lighting, noise]]>

<![CDATA[Introduction: Noise is unwanted sound which comes from various working tools that can cause hearing loss on workers expressed in decibels (dB). The ambient noise value in the workplace is 85 dBA. Ambient temperature in the workplace that is too hot is dangerous for the health of individual workers because it can result in various mental and physical health disorders. Methods: This research was conducted at one of the Ship Production Companies in Indonesia in March to June 2018. This type of research was descriptive and the design of this study was cross-sectional. The variables of this research were technical control, administrative control, and PPE control. The purpose of this study was to describe the efforts of controlling one of the Ship Production Companies in Indonesia in controlling heat stress and noise. The data used were primary data and secondary data. Result: One of the Ship Production Companies in Indonesia still had high heat and noise pressure. Three control efforts have been made including administrative control, technical control, and the use of PPE. The results shown in terms of technical control still did not meet the requirements because not all technical efforts were made. Meanwhile, administrative control and PPE control have met the requirements. Conclusion: Among the three control efforts that have not met the requirements yet are technical licensing while those that have met the requirements are administrative control requirements and the use of PPE.Keywords: heat radiation, noise, ship production]]>
