Tumpeng and penek are important facilities on making of banten according to Hinduism in Bali. The use of tumpeng and penek on banten strongly associated with the believing on Tri Rnam and Panca Yadnya which based on the local wisdom of Tri Hita Karana, where its use continuously and in line with the implementation of religious ceremonies. The necessity of tumpeng and penek is constantly increases then it needs more effective and efficient in the creation, in order to fulfill the market demand. Tumpeng and penek making process is now done by home industry. Although by home industry, but the production process is still done on the floor with no ergonomic body posture and the drying process is done by a dryer without heat insulation that effects to the woman employees. These conditions affect the working capacity and energy efficiency of the fuel of dryer. Based on the above problems it is necessary to study the synergy of ergonomics and mechanical systems which in this case is expressed as synergy ergo-mechanical systems by ergonomically synergy between the employees and the mechanical system of the dryer in order to increasing labor productivity and efficiency. This is done by redesigning the work system and dryer system that aims to increasing working capacity by reducing workload, decreasing complaints of musculoskeletal, decreasing in fatigue, increasing of comfort, improving energy efficiency of fuel. Research experiments conducted within subject design by involving 15 respondents that randomly selected, all of whom studied in 2 (two) periods, Period I and Period II. Period I is the period prior to the application of synergy ergo-mechanical system, and the second period is the period after the application done of synergy ergo-mechanical system. Each carried in three days period, with washing out of 2 days and 5 days of adaptation. Data were analyzed with descriptive and test for normality using the Shapiro-Wilk. Different test has been done when the data were normally distributed with a t-paired, unless analyzed by the nonparametric Wilcoxon test with the significant-degree of about 5%. The results showed that of about 21.90% reduction occurred in workload, musculoskeletal complaints of about 15.10%, about 22.23% of fatigue, increasing employee comfort of about 59.18%, and fuel efficiency of dryer of about 13.29%. It concluded that synergy of ergo-mechanical system applications improves energy efficiency of dryer fuel and work capacity of industry women employees of banten facility at Blahbatuh Gianyar Bali.
