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: Optimization of work productivity is needed by company. Optimum products will increase the company's profit. Productivity can be improved by method of working, time study, and salary. Working methods need to be studied in order to reduce fatigue of work so the time needed to produce a product becoming decreased. The aim of the research is to determine elements of work on oil palm harvesting activities based on patterns of working time, determination time standard on elements of the work in activity of oil palm harvesting. Research stage in oil palm harvesting activities were introduction, data collecting, data processing, and improvement. Standar time for verify the maturity of fruit (Ve) on terrace topography (T)- dry land (K)-the height of trees 0-3 m (H1) is 3.21 second, Ve on T-K- the height of trees 3-6 m (H2) is 2.39 second, Ve on flat topography (F)-K-H1 is 3.45 second, Ve on F-K-H2 is 4.59 second, Ve on F-wet land (B)-H1 is 4.27 second. Standar time for prepare harvesting tool (Pr) is 6.45 second. Standar time of cutting the fruit and stem of (Cu) on the T-K-D is 29.86 second, Cu on T-K-E1 is 38.47 second, Cu on T-K-E2 is 57.91 second, Cu on F-K-D is 14.19 second, Cu on F-K-E1 is 25.88 second, Cu on F-K-E2 is 21.06 second, Cu on F-B-D is 21.13 second. Standar time for moving the stem (Ba) is 9.53 second. Standar time for cutting the stalks (Ck) is 1.74 second. Standar time picking up the fallen fruits “brondolan” (Br) on T-K-H1 is 51.48 second, Br on T-K-H2 is 20.32 second, Br on F-K-H1 is 37.03 second, Br on F-K-H2 is 51.75 second, Br on F-B-H1 is 29.67 second. Standar time for loading fruit (Lo) is 3.75 second. Standar time for moving by carrying empty “angkong” (UDA) of 9.39 second, moving by carrying fruit (MoT) is 8.68 second, moving by carrying fruits and “angkong” (MoAT) is 13.52 second, moving (UDK) is 15.07 second. Standart time for unloading (Un) is 6.56 second. Standar time for avoidable delay is 10.83 second.
