Abstract

Clove farmers who are currently still using wood as a footrest mounted on bamboo, more specifically, this invention relates to the design of a new footing design for bamboo stairs using metal clamps as a substitute for wooden steps which are often at risk of breaking. To overcome existing problems, craftsmen need to be given a bamboo ladder (Banggul) for picking clove flowers that is ergonomic and safe using strong and light metal clamps as an ergonomic footrest that can be installed and removed and the distance of the bamboo steps can be adjusted according to anthropometry. the farmer’s knees are high so that when he climbs the bamboo steps his working attitude is natural. The results showed that the workload of farmers reached 127,54 ± 4,90 dpm (heavy workload), while the resting pulse 75,61 ± 0,506 dpm or experiencing an increase 51,935± 2,19 dpm. Musculoskeletal complaints before work 30,32 ± 1,52 and after-work complaints score 51,20 ± 5,021. Fatigue scores after work increased from before work 32,10 ± 3,354 while the fatigue score after work increased to 55,11 ± 4,321.
