Abstract

This paper presents a study in batik industry with the objective of determining any musculoskeletal disorders (MSDs) among canting batik workers in Kuala Terengganu. The MSDs symptoms were identified through questionnaires modified from a Standardized Nordic Questionnaire (SNQ) and from observational techniques by using a postural analysis tool, Rapid Upper Limb Assessment (RULA) and Rapid Entire Body Assessment (REBA). The results of questionnaires revealed that MSDs occurred at a high rate which the highest rates of MSDs prevalence were reported in shoulders (64.5%). By assessing postural using the REBA software, the score 4 placed it in medium risk level. However, there are other factors contribute to the existence of MSD such as prolong standing, repetitive movement and poor workstation design. These parameters are not taken into account in the RULA and REBA analysis. Thus, designing an ergonomic workstation may prevent awkward postures to provide a maximum comfort to the batik workers and consequently enhance the productivity.

Summary

Introduction

Batik industry is one of the oldest industries in Malaysia. The industry of batik in Malaysia has been existed around the year of 1921. Throughout the years of its existence, the industry contributes to the Malaysian economic well being by first, creating jobs and business opportunities in rural areas [1]. In Malaysia, there are two major types of batik processes, which are Hand-drawn and Block-printed batik. Hand-drawn batik is where designs are drawn on fabric or cloth with hot liquid wax by using a metal object called “canting”. When the wax outlines are done, the workers use the brushes to paint the dyes within the outlines. Most of the handdrawn, canting batik artists or workers are young women whereas for block-printed batik is mostly dominated by men [2]
