The work environment becomes one of the motivations for someone to work. The climate of working environment is very important for a person, especially for medical staffs who actually handle and deal with sick people. Medical officers are required to always be friendly, agile, discipline and polite in front of patients thus the patient feels comfortable and quiet. This study aimed to analysis the relationship between work environment and patients’ safety climate. This study was conducted with questionnaires. Based on the survey results, it was revealed that the hospital environment determines the form of services provided to patients. The working environment has positive relationship to patients’ safety climate. At the hospital, there are latent conditions that may be a risk of accidents that come from heavy work load, management and inadequate supervision, work environment filled with pressure and inadequate communication systems. Work environment contributes greatly because the overall work in providing services to patients requires good teamwork.
Introduction: Bullying does not only occur in the school environment. It can also happen at the workplace. There have been several definitions on bullying in the psychological literature but, in general, bullying is described as aggressive behavior by a person or group of people who feel more powerful, with the aim of hurting, humiliating, or isolating victims who feel helpless (Salmivalli, March–April 2010) (Gredler, 2003) Bullying can affect employee's satisfaction with life, which negatively relates to job satisfaction and mental health status of workers (Gabriele , et al., 2015). Work-related losses due to work accidents caused by fatigue triggered by workplace bullying will also increase if the psychosocial hazards caused by bullying are not managed properly and correctly (Young-Ran & Jeong-Won , 2016) (Rohit, et al., 2009) (Ma, et al., 2010). Research related to workplace bullying is still difficult to find in Indonesia, even the existing reports on this topic are barely enough to explain how this phenomenon is handled this country. Bullying has been widely researched, but the majority of the studies are performed in school settings or adolescent settings. There has not been any in-depth research on bullying that has been conducted comprehensively in work settings (Silviandari & Helmi, 2018). This study aims to determine and examine the incidence of workplace bullying in the energy sector or the power generation industry by involving seven power plants throughout Indonesia. Method: This was a cross-sectional study involving 219 workers in the power plant industry who were above 17 years of age and with a work experience of at least 6 months. These workers participated in this study by filling out the Negative Acts Questionnaire-Revised (NAQ-R). Results: The results of the analysis showed that there was no comparison of bullying incidents among the seven power plants (F = 0.71, p = 0.135) and that the bullying level in these 7 power plants was low (mean= 26.7), with the highest mean was found in Southeast Sulawesi (mean=27.9). Conclusion: This shows that the incidence of bullying in the seven power plants is in the low category, with the highest tendency of bullying seen in the power plant in Southeast Sulawesi.
Mental fatigue among coal mining operators was related to driving activities that require high concentration. This study aimed to determine factors that contributed to mental fatigue among coal mine operators in Indonesia, specifically in Kalimantan and Sumatra, after a one-year COVID-19 pandemic. This cross-sectional study was conducted among 480 operators from two companies and seven sites. A self-administrated questionnaire in the Google Form was used to measure mental fatigue, the non-work-related factors (age, education, marital status, residence, and stress level), and work-related factors (working periods, shift pattern, type of shift, and work area in mining). The data analyzed using Chi-square and binomial logistic regression showed that the prevalence of mental fatigue was 32.3%. Operators with moderate stress and working in the pit area demonstrated a significant association with mental fatigue (p-va lue<0.001). Multivariable analysis showed that medium stress (ORadj: 2.11, 95% CI: 1.41 to 3.15) and working in the pit (ORadj: 2.27, 95% CI: 1.45 to 3.57) had a positive association with mental fatigue. Thus, the pit condition and stress levels were the dominant factors influencing mental fatigue and became points to manage mental fatigue in coal mining operators in Kalimantan and Sumatra.
One of preventive action methods of hearing loss that number tend to increase is by using brick that made from Styrofoam which is expected to have the ability as a soundproof that can be used to control the noise. The aim of this research is to assess the use of sound absorption material in which utilizing Styrofoam to reduce the noise exposure. In this study, cement and find aggregate that contain the Styrofoam and sand are mixed with the composition 1:4 and 1:6 and also by adding the polystyrene waste as much as 0%, 20%, 40%, 60%, and 80%. To determine the acoustical property of the mixture, the sound absorbing coefficient (α) was determined by using Four Microphones Impedance Tube (ISO 140-3). The results showed that the highest absorption coefficient value was at frequency 800 Hz by adding 80% Styrofoam for the composition of 1:4 at 0.4100 dB and at the frequency 800 Hz by adding 40% Styrofoam for the composition 1:6 at 0.5870 dB. Based on the results of this research, further study to potentially use Styrofoam as noise barrier is suggested.
