Pine resin is one of the non-timber forest products commodity that has excellent prospects. Pine resin harvesting is generally divided into two main activities: tapping and collecting works. Collecting activity that is commonly done under manual technique is classified as manual material handling that can trigger musculoskeletal disorders (MSDs). This work posture study offers an overview of MSDs disruption level faced by workers. Therefore, the proper corrective action can be taken. Motion sequences in selected work cycles were captured by using the Kinovea software. Work posture analysis was performed by a combination of the natural range of motion (SAG), Rapid Upper-Limb Assessment (RULA), and Rapid Entire Body Assessment (REBA). SAG analysis shows that the body's parts having a high probability of being injured are the back and shoulders. Work posture analysis using RULA and REBA verified that bending or half bending may cause MSDs. The ergonomics risk in these positions might be higher due to the influence of load and repetitive factors. Reducing the posture of bending/half bending, reducing the weight of the resin bucket, and taking a short break/rest in between work activities should be considered as potential strategies in reducing the ergonomics risks that may occur during the resin collection work.
