Manual material handling if done inappropriately can pose a risk of injury to the body, mainly in the spine, which is usually referred as musculoskeletal disorders (MSDs). Based on direct interview with warehouse workers of PT. X, it is known that in the lifting or transfering mineral water activity often causes pain in the waist and spine. This study is intended to analyze the work posture and the load level that is safe for workers to reduce the risk of MSDs, the analysis is carried out with the Recommended Weight Limit (RWL) method. From the calculation gained RWL origin = 15.36kg / 34.07lbs and destination RWL = 18.54kg / 41.12lbs. Then the origin LI value = 0.9 and destination LI = 0.8. From the results of the Lifting Index can be concluded that the risk level of this work is low and there is no problem with the lifting work. The weight of load raised does not exceed the recommended lifting limit, so there are no repairs to the work needed, but the activity must keep to get attention so the LI value can be maintained and the activity does not bear the risk of spinal injury.
Grinding activities produced 31% accident cases that occurred repeatedly and had the same cause. Most of them were investigated and were proved to be caused by human error. The study aims to obtain the value of Human Error Probability (HEP), thus, it could be employed as prevention and controlling consideration. HEP value was obtained by finding the value of. Success Likelihood Index (SLI). SLI value could be obtained using questionnaires and Performance Shaping Factor (PSF) assessment which had been filled by expert judgment. The scenarios were developed to predict and reduce the occurrence of human error as applied to Success Likelihood Index Method (SLIM). This research illustrated the factors that affected errors in the grinding process were procedure, fatigue, complexity, training, and experience. The task that contained the highest error value was in the first task (use PPE following predetermined). While the task which included the lowest HEP was task 2 (prepare documents according to pre-defined). As part of efforts to reduce the error probability values grinding process, it recommended reducing the probability of error by increasing the value of PSF, ranging from improved procedures, reduction of fatigue of the workers, the reduction of the complexity of the job, increased training for workers, and increased workers’ qualification through work experience history.
Kru kapal merupakan sumber daya manusia yang sangat berperan penting dalam pengoperasian kapal, dari hasil observasi dan wawancara singkat didapatkan beberapa kru kapal mengalami keluhan yang mengarah pada kelelahan kerja dan terjadinya insiden tabrakan kapal karena faktor kelelahan. Penelitian ini bertujuan untuk menganalisis hubungan karakteristik individu dan beban kerja dengan kelelahan kerja pada kru kapal di PT.X. Penelitian ini berupa observasional analitik dengan pendekatan cross sectional. Populasi pada penelitian ini adalah kru kapal tunda sebanyak 133 responden dengan total sampel sebanyak 100 responden. Pengumpulan data dilakukan melalui wawancara menggunakan kuisioner IFRC untuk mengukur tingkat kelelahan subjektif dan melakukan observasi secara langsung. Analisis data pada penelitian ini yaitu analisis univariat dan multivariat yang menggunakan uji chi-square. Hasil penelitian menunjukkan bahwa karakteristik individu yang berhubungan dengan kelelahan kerja yaitu pada lama kerja dan status gizi. Beban kerja memiliki hubungan dengan kelelahan kerja. Saran bagi perusahaan yaitu adanya forum diskusi perihal evaluasi kerja, pemilihan menu diet dan monitoring, pemberian program olahraga bersama, pengawasan sistem lembur. Saran bagi pekerja yaitu tidak memaksakan diri apabila timbul gejala, melakukan istirahat dan stretching, mengkonsumsi air mineral, menjaga pola makan dan pola hidup sehat. Saran bagi penelitian selanjutnya yaitu sebagai sumber referensi untuk penelitian lebih mendalam terutama pada faktor lingkungan kerja dan beban kerja mental.
Preparedness is a part of the disaster management process which aims to prevent and minimize disaster risk which is pro-active before a disaster occurs. Fire disasters can occur anywhere, including in the Islamic boarding schools, this is because in the Islamic boarding schools there is not only a teaching and learning process, but there are additional activities such as fulfilling their daily needs such as the students also live in the cottage during their studies. This research was conducted in July-August 2020 which aims to analyze the relationship between the level of knowledge and attitudes of students towards fire disaster preparedness at Islamic Boarding School Pondok Karya at Manado City. Type of this research using analytic survey with a cross sectional approach, with a total sample of 89 people was taken using accidental techniques. The results of this study showed that as many as 60 students (67.4%) have a level of preparedness that is ready to cope with fire disasters with a good level of knowledge (47.2%) on fire management procedures although only 33 students (37.1%) knew how to use fire extinguisher. Statistical test result using chi square test show that there is a relationship between the level of knowledge (0.002) and attitude (0.000) with the level of preparedness in fire disaster preparedness at Islamic Boarding Scholl Pondok Karya at Manado City. Recommended for Islamic Boarding School Management are required to provide education on fire disaster management preparedness to students at least once a year, so that if a fire disaster occurs, the risk can be minimized.
Musculoskeletal complaints are the most frequently reported complaints to workers. Cracker industry workers in Kedungrejo Village,Sidoarjo sit for more than 6 hours doing repetitive movements which are at risk of developing complaints of Musculoskeletal Disorders (MSDs). The aims of this research was to analyze the relationship between work position with complaints of MSDs in cracker industry workers in Kedungrejo village,Sidoarjo.The type of this research is an analytical survey with a cross-sectional study. The research population was all cracker industry workers at village Kedungrejo. The research sample of 46 respondents was taken by simple random sampling technique. Data related to respondent characteristics like work position and MSDs complaint obtained from direct observation to the field with using Rapid Upper Limb Assessment (RULA) assessment and interviews with workers using Nordic Body Map (NBM). Data analysis using SPSS with statistical test rank spearmen.Statistical test results showed that almost half of the respondents (43.5%) had complaints of MSDs at a very high level and most (60.9%) had work position with a low risk category. The results showed that there was a significant relationship between work position and MSDs complaints in cracker industry workers with a value of 0.033 < 0.05 in the test rank spearmen. The strength of the relationship between variables is seen from the correlation coefficient with a result of 0.315 which means weak. The direction of correlation is positive, which means that poor work position can increase MSDs complaints.The conclusion is research that there is a significant relationship between work attitudes and MSDs complaints in cracker industry workers. Suggestions for the cracker industry to replace workers’ chairs with ergonomic chairs and for cracker industry workers to stretch before working and consuming water on the sidelines of work.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
