Evaluasi Postur Kerja Operator Pemasangan Fire Brick Berbasis Metode Rapid Upper Limb Assessment dan Work Ergonomic Risk Assessment Di PT ABA

A service provider is known as a job that profoundly depends on human work. Musculoskeletal disorder is considered a risk in such work. PT. ABA is a contractor service company that provide some services. The fire brick installation is a part of the refractory project, which is carried out continuously at the customer's request. Early results using the Nordic Body Map questionnaire found severe risk, which may lead to wellbeing difficulty. This study aims to evaluate musculoskeletal disorder risk due to inappropriate posture in fire brick installation activities. Rapid Upper Limb Assessment and Work Ergonomic Risk Assessment are ergonomic risk approaches used in this study. This research found two final scores using RULA and WERA calculation. RULA final score is 44, classified as a medium score. The evaluation results of the RULA method obtained a final score of 7 with an extreme condition. An urgent improvement is a necessity in order to improve posture and work positioning of fire brick installation.

Ergonomic Risk Assessment during an Informal Hand-Made Cookware Operation: Extending an Existing Model

The work conducted in the informal sector is highly variable within and between days. Characterizing ergonomic exposures remains a challenge because of unstructured work settings and schedules. The existing ergonomic risk assessment tools have been widely used in formal work settings with a narrow range of exposure, and for predefined tasks that primarily constitute a daily routine. There is limited information in the literature on how they have been applied in informal workplaces. The aim of this study was to extend an existing risk assessment tool and to evaluate the applicability of the extended tool by assessing ergonomic exposure related to hand-made cookware operations. Eighteen hand-made cookware makers were recruited from six sites. A walkthrough risk assessment questionnaire was used to collect information on workers, tasks, work stations and workplace structures. The Rapid Upper Limb Assessment (RULA) screening tool was extended by including duration and vibration. An action priority matrix was used to guide intervention. According to the RULA action levels, the workers required investigation and changes soon, and immediate investigation and changes. The use of an action priority matrix was appropriate, and indicated that all the workers assessed were within the high to very high exposure domain and required immediate corrective measures. The methodology used proved to be an effective and reliable strategy for identifying ergonomic exposure among hand-made cookware makers.

Implementation of Kinetic and Kinematic Variables in Ergonomic Risk Assessment Using Motion Capture Simulation: A Review

Work-related musculoskeletal disorders (WMSDs) are among the most common disorders in any work sector and industry. Ergonomic risk assessment can reduce the risk of WMSDs. Motion capture that can provide accurate and real-time quantitative data has been widely used as a tool for ergonomic risk assessment. However, most ergonomic risk assessments that use motion capture still depend on the traditional ergonomic risk assessment method, focusing on qualitative data. Therefore, this article aims to provide a view on the ergonomic risk assessment and apply current motion capture technology to understand classical mechanics of physics that include velocity, acceleration, force, and momentum in ergonomic risk assessment. This review suggests that using motion capture technologies with kinetic and kinematic variables, such as velocity, acceleration, and force, can help avoid inconsistency and develop more reliable results in ergonomic risk assessment. Most studies related to the physical measurement conducted with motion capture prefer to use non-optical motion capture because it is a low-cost system and simple experimental setup. However, the present review reveals that optical motion capture can provide more accurate data.

Analisis Faktor Risiko Nyeri Punggung Bawah Pada Perawat Di Rsud Dr. Murjani Sampit

Low back pain (NPB) is one of the most common musculoskeletal disorders in everyday life. NPB is pain that is felt in the lower back and is usually local pain or radicular pain or both. This pain can be caused by poor posture when standing or sitting, bending / twisting, lifting weights incorrectly and so on. The cause of NPB often occurs in inpatient nurses. This case report is located in dr. Murjani Sampit, Kotawaringin Timur, Kaliantan Tengah. The purpose of this case report is to determine the risk factors for low back pain in nurses at dr. Murjani Sampit. The method used is a questionnaire to determine individual factors and the Brief Survey method for ergonomic risk assessment. A case study was conducted on 2 inpatient nurses who had a history of Lower Back Pain. Based on the results of the ergonomic risk assessment using the Brief Survey method, the highest work risk was in the back region with a score of 4. Characteristic factors of respondents including gender, BMI, work experience, smoking behavior and exercise habits did not have a significant relationship with the incidence of NPB. Based on the results of statistical tests obtained from several case studies and research shows that only the length of sitting and the length of standing that affect the incidence of low back pain
