Judul: Workload analysis and optimization of harvesting procedure at sari lembah subur oil palm Plantation, Riau
Abstrak: Nowdays, oil palm harvesting process is still done manually which led to many variations in quality of harvest, workburden or physical disorder. This study aimed to determine the rate of energy consumption, workburden level and recovery time so that the best procedure of harvesting can be obtanined based on the productivity and labor’s capacity. This research was conducted with heart rate analysis approach, the standard time of harvest and work productivity. This study was conducted at 8 harvesters that have been observed as subjects that grouped by age, variations in topography and the use of harvesting equipment. The result showed that the rate of energy consumption for subjects aged < 30 years was higher than subject aged > 30 years. Based on the topography, harvesting which is done in terraced area required energy consumption rate more than flat area. Based on the using of tools, harvesting which is done using “egrek” have energy consumption rate higher than “dodos”. Working in pairs can be the best alternative for harvesting oil palm in F-B-D, T-K-E and F-KE. At F-B-D condition harvesting activities is done by 2 people aged > 30 years old. Then, at T-K-E and F-K-E, harvesting is conducted by 3 harvesters that consisted of 1 person aged > 30 years for doing the first subsystem and 2 people aged < 30 years for doing the second subsystem.

Abstrak: Oil palm is one of the main plantation commodities in Indonesia. The important factors that must be considered to produce palm oil (CPO and PKO) with a maximum quality is the manual harvesting method. The aims of this research is to identify the labour work load and energy cost in the harvesting activities, and based on that to find out the ideal working capacity of the harvesting worker. The work load and work energy cost analysis were conducted based on heart rate measurement. Eight workers of under 30 years of age and eight workers of over 30 years of age were observed as the subjects. The tree height and relief of the land were the main working variables which took a place in the experimental design. In the case of subjects aged > 30 years old, it can be seen that the harvesting energy consumption rate using egrek in R2 land (6.23 kcal /stem) has a lower value than the R3 land (7.71 kcal/stem) as well as in the case of subjects aged < 30 years old with a value of R2 (6.47 kcal/stem) and R3 (7.99 kcal/stem). Moreover, the energy consumption rate of harvest activity using dodos is also lower for the subjects aged > 30 years old (5.33 kcal/stem) compared to subjects aged < 30 years old (5.70 kcal/stem). Based on this value, it noteworthly shows that the subject aged < 30 years old has the greater energy consumption rate (work load). The amount of energy consumption rate is highly influenced by the skill level of workers which then resulted a greater fatigue level. Briefly, the greater energy consumption rate, the lower ideal capacity most likely to be generated
