Some works at study area were still done manually, such as carrying Thin Brown Crepe (TBC). Two kinds of carrying methods were using the two-wheeled equipment and carrying manually on the head of workers with 70 m distance, so workers feel exhausted and often complain of pain in their shoulders, backs, waist and other body parts. This study aimed to redesign the conveyance based on the anthropometry method. The redesign would help workers work comfortably hence reduce the complaints of pain, increase productivity, reduce human error, and minimize the cost of material handling. Direct interviews with key persons, questioners, and direct measurement were implemented to obtain data and related information. The anthropometric method was employed as a designing method to develop improved TBC’s transport equipment for the workers. Test performance was then conducted to observe the worker’s complaint, productivity, human error rate, and the carrying time. The result of the study showed that the redesign of TBC conveyance could reduce the complaints of the workers, the productivity increased by 116%, and the human error rate tended to be decreased. The carrying capacity also increased from 150 kg to 300kg. Conveying process could reach 3.2% cost efficiency, thus the company could save TBC’s conveying cost by Rp 8.62 per minute.
