The role of workers' perceptions towards the uncertain result of ergonomic program

Manual activities of workers in palm oil factories cause pain complaints that can be resolved with an ergonomic program. However, the uncertainty of the success of the ergonomic program requires active involvement from workers. This study aims to discuss the role of workers’ perceptions towards the success of the ergonomic program intervention in palm oil mills. By referring to the theory of reasoned action and technology acceptance model, acceptance of workers to ergonomics programs are influenced by perceived usefulness, perceived ease of use, and perceived trust. All these research variables were analyzed simultaneously using Partial Least Squares Structural Equation Modeling (PLS-SEM) software, in which data were obtained from questionnaires given to 280 people working in 20 palm oil mills in North Sumatra Province. The sampling method used is simple random sampling and model estimation is performed using PLS regression algorithm and resampling bootstrapping method. The result shows that perceived usefulness has the biggest effect on the success of the ergonomic program, followed by perceived trust and perceived ease of use, which has a smaller effect. This study focuses on workers’ perception that needs to be considered for facing uncertain results in implementing an ergonomic program.

Ergonomic Program and Nursing Intervention in Nursing Students

Ergonomics position is the position that should be done while working on a such procedure to improve work security, work efficiency and reduce risk factors. Nurses are the health workers with the biggest exposure risk factor. The results of the preliminary study showed that more than 50 percent of the students are still doing the wrong position when performing nursing interventions. This study was conducted at Nursing Study Program of Udayana University wich aims to know the effect of comprehensive ergonomic program on ergonomic position of students when performing nursing interventions. A quasy experimental design with action research application was used to analyze the effect of an ergonomic program on knowledge, attitude and behavior of nursing students. Nursing students of Udayana University was the population of this study and simple random sampling techniques was used with sample size of 50 respondents. Evaluation of this study were involves the readiness of institutions to apply programs and modifications according to institutional conditions. The results showed that there is a significant effect of ergonomic program on student's knowledge, attitude and behavior related to ergonomic standard in performing nursing interventions with statistic test result p <0,05. Student behavior can be improved by increasing the students' knowledge on the ergonomic position when performing nursing intervention. Based on the results of this study, the institute is expected to provide knowledge about the importance of ergonomics position to nursing students, either through counseling or by incorporating into one of the subjects in the nursing curriculum.
