Summary: | Scientific evidence show that manual handling devices are one of the
effectives controls that can lower the physical demands of manual material handling
(MMH) activities. Incidence and severity of the musculoskeletal injuries might
happen to workers while company’s productivity, product quality, and overall busi�ness competitiveness also will be affected. However, few studies had been done
regarding on manual handling devices provided in the industries especially in term
of user satisfaction on the usability of the devices when performing their job and task.
The aim of this study is to develop a survey instrument for the evaluation of worker
satisfaction on usability of manual handling device among warehouse worker in
manufacturing industry. A set of questionnaires was developed which consist of three
sections; demographic profile of respondent, work nature and discomfort survey and
worker satisfaction on the usability of the manual handling devices. The content of the
questionnaire was derived through extend literature reviews and expert’s opinions.
A pilot study was conducted at four manufacturing companies in their warehouse’s
operation. The reliability and validity of the instrument were determined through
Cronbach’s Alpha, face validity and content validity. Cronbach’s Alpha values for
each section of the questionnaire range from 0.937 and 0.961 while the value for
Cronbach’s Alpha for all 35 standardized items is 0.921. The finding shows that the
survey instrument has face and content validity at acceptable level. In conclusion,
finding indicated that this instrument had acceptable and adequate reliability and validity to meet its objectives. The survey instrument now ready to be distributed in
larger data sets. |
