Abstract

Introduction: Noise pollution from machine operations is one of industry's long-standing issues, especially in the textile manufacturing industry. High noise levels produced by weaving machine operation can harm employees' health, most notably hearing loss and stress at work. Since 1975, IT Co. Ltd., one of the biggest textile corporations in Surakarta, Indonesia, has struggled to find a solution to the issue of excessive noise, particularly in the weaving manufacturing facility. This study aims to determine the effect of employing earmuffs as a type of intervention to alleviate hearing loss complaints and subjective stress on weaving workers who are exposed to high-intensity noise. Methods: A time series design was used in this quasi-experimental study. This study’s participants were divided into 2 groups. The first group was weaving workers who used earmuffs as ear protection (Intervention Group), and the second group did not use earmuffs (Control Group). Data collection was carried out for 6 working days to see whether there was a significant effect of using earmuffs on hearing loss complaints and subjective stress. Results: From the second to the sixth day, using earmuffs as ear protection did not significantly reduce hearing loss complaints. However, it showed significant findings that increased the average score of subjective stress. Conclusion: Using earmuffs should protect the ears from noise exposure and its effects on workers' health. However, it has been shown that using earmuffs can increase the average score of hearing loss complaints and subjective stress.

Abstract

Introduction: Occupational health must be considered in the workplace. Cases of overweight and obesity among workers in the manufacturing sector have increased. This study analyzes the relationship between physical workload and personal factors related to nutritional status among manufacturing workers. Methods: This study used an observational analytic study with a cross-sectional design. The variables of this study were physical workload, nutritional status, and personal factors such as gender, educational level, exercise habits, and smoking habits. The sample in this study was 239 workers in the manufacturing industry, and it was obtained using random sampling techniques. Data were analyzed using the Spearman correlation and coefficient contingency test. Result: More than half of the total cases of overweight and obesity occur in manufacturing workers who have a low physical workload. More than half of the respondents are female, do not have a high school education, and have never exercised. Most do not have a smoking habit. The results showed that physical workload (p=0.001), exercise habits (p=0.001), gender (p=0,004), and educational level (p=0.037) were related to nutritional status. In contrast, manufacturing workers' smoking habits were not associated with nutritional status (p>0.05). Conclusion: Physical workload, exercise habits, gender, and educational level have a relationship with nutritional status among workers, it is recommended that workers must increase their exercise routine such as implementing scheduled sports shifts for workers and providing sports facilities in companies so the case of being obesity can be decreased.

Gresik Regency is one of the regencies with lontar sewu tourist destinations that are quite interesting to visit. The number of emerging tourist destinations in various regions makes the manager consider the safety aspects of visitors and employees working at tourist sites. Therefore, tourism managers need to develop contingency plans and mitigation measures to improve preparedness and reduce the adverse impacts of disasters. Purpose: This service activity aims to map evacuation routes and educate employees at tourist sites with disaster mitigation socialization activities related to knowledge and awareness of disasters and a simulation of disaster occurrences in Gresik Regency tourism, namely Edu Wisata Lontar Sewu, Hendrosari Village, Menganti District. Methods: The method of activities carried out is divided into 3 main stages, namely 1) the planning stage starting from exploring partner problems, reviewing the program target areas, preparing proposals, mapping evacuation route points at tourist sites; 2) the implementation stage consists of the location mapping stage, Focus Group Discussion (FGD), visualization stage, installation stage and socialization activities; 3) The last stage is the evaluation stage consisting of a question and answer session at the end of the socialization session, and 2) disaster simulation by participants. Results: The result of this service activity is that 21 evacuation routes have been installed at tourist sites, the installation of evacuation route maps at 5 location points that have the potential to have many visitors, and the presence of gathering point locations at tourist sites. In addition, related to the results of non-structural disaster mitigation, showed that participants looked enthusiastic when socialization related to disaster mitigation was carried out and they were able to take part in disaster simulation activities properly and correctly and carry out self-rescue efforts by following the evacuation route that had been installed and heading to the gathering point according to the time. determined is 1 minute 25 seconds. Conclusion: Employees at tourist sites can make mitigation efforts by the directions at the time of socialization, namely by running in the direction of the evacuation route that has been installed at the tourist location and can go to the meeting point location according to a fast time of 1 minute 25 seconds.

Abstract

Land Surface Temperature (LST) is a parameter to estimate the temperature of the Earth’s surface and to detect climate change. Papua New Guinea is a tropical country with rainforests, the greatest proportion of which are located on the island of New Britain. Hectares of rainforests have been logged and deforested because of infrastructure construction. This study aims to investigate the change in land surface temperatures on the island from 2000 to 2019. The temperature data were taken from National Aeronautics and Space Administration (NASA) Terra satellites and were analysed using two statistical models: spatial and temporal. The spatial model used multivariate regression, while the temporal one used autoregression (AR). In this study, a cubic spline fitted curve was employed because this has the advantage of being smoother and providing good visuals. The results show that almost all the sub-regions of New Britain have experienced a significant increase in land surface temperature, with a Z value of 7.97 and a confidence interval (CI) of 0.264 – 0.437. The study only investigated land surface temperature change on New Britain Island using spatial and temporal analysis, so further analysis is needed which takes into account other variables such as vegetation and land cover, or which establishes correlations with other variables such as human health.

Abstract

Background: Oxidative stress can cause health problems for workers and affect productivity for workers. Low-Density Lipoprotein (LDL) and Malondialdehyde (MDA) levels a biomarkers for systemic oxidative stress. Car painting and body repair businesses play a crucial role in preventing corrosion and damage from crashes by employing a variety of processes. The worker in the stage poses the highest risk of exposure to the chemical substance known as toluene. Objective: The purpose of this study is to investigate the relationship of toluene intake with Low-Density Lipoprotein (LDL) and Malondialdehyde (MDA) levels. Methods: This study employed an observational research design with a cross-sectional method. All 30 car painting workshop workers in sanding, caulking, painting, polishing, and finishing are included in this research. Workers were measured for exposure to Toluene and Low-Density Lipoprotein (LDL) and Malondialdehyde (MDA) levels. Data were analyzed descriptively and statistically. Results: Almost half of the total workers are adults. More than half of the total workers have a working period of 8 hours/day, have a working period of up to 10 years, and BMI in the normal category. Only a small number of workers do not smoke. Toluene exposure that enters the body of workers has more than the reference dose and is found in more than half of the total workers. Most workers have optimal LDL. More than half of the total workers have low MDA. The results of the Toluene exposure test with LDL obtained p = 0.098, and toluene exposure with MDA (malondialdehyde) obtained p = 0.045. Conclusion: There is a relationship between Toluene and MDA, but not with LDL. This indicates the need for efforts to anticipate Toluene exposure in companies to prevent oxidative stress, preceded by an increase in MDA.

Abstract

Introduction: Hearing loss is identified to impact 466 million people globally, with workplace noise contributing to 16% of adult hearing function impairment. To address the challenges, using personal protective equipment, such as earmuffs, has become a practical solution. Aims: This study aims to analyze impact of using earmuffs on hearing function impairment and fatigue among weaving workers at PT IIPT Surakarta. Methods: The quasi-experimental study used the time series design method, comprising 33 weaving machine operators. Data were collected over 6 working days, namely the first day before the intervention and the following 5 days during the intervention. A questionnaire with tested validity and reliability was used to assess hearing function impairment and fatigue. Results: The results showed that there was a significant variation in the average scores for hearing function impairment and fatigue during the 6 days of earmuff use. Furthermore, the lowest average score was recorded on the first day, while the highest was recorded on the sixth day. Conclusion: This study shows that earmuffs designed to protect workers from the harmful impact of noise increase the average levels of hearing function impairment and fatigue. Consequently, further studies are recommended to evaluate the effectiveness of the sound-absorbing materials used in earmuffs, as different materials can offer varying benefits in absorbing various sources of sound.
