Oil palm fresh fruit bunch (FFB) handling processes, i.e harvesting, loading, and transporting to the Palm Oil Mill are interrelated activities because each of them contributed to the degradation of oil palm fruit quality. This paper presented studied among factors that together in series interfere FFB quality. FFB quality parameter observed was Free Fatty Acid (FFA) content. Experiment was conducted by measuring FFA content of FFB at each step of handling processes, i.e harvesting, transportation in plantation block, loading into truck, and transportation to the palm oil mill. Interrelationship among factors was built using dynamic modelling. Output of dynamic model simulation showed that there was differences of FFA content among different handling conditions. A slight difference on FFA content was observed between harvesting in mineral land and peatland and among different plant heights. Loading into truck was a handling step that had biggest contribution to quality degradation due to FFB bruise. FFBs laid on the base of truck bin suffered more bruise that resulted in higher FFA content. Manual loading of FFB harvested from mineral soil by throwing to the bottom of truck bin resulted in FFA content of bruised fruit by 5.5%, higher compared to those of the top layer which was 4.5%. Model also showed that FFA content increased due to series handling steps, compared with natural degradation. Proportion of good FFB can be used to control the whole FFA content. Without mixing, bruised FFB produced FFA content of 9.95 %, while mixing bruished and good fruit at a ratio 20 % : 80 % resulted in FFA content of 2.82 %. Increasing bruise fruit proportion from 10 % to 20 % resulted in higher FFA content of fruit harvested on mineral land than those harvested on peat land (0.88 % compare to 0.80 %), and resulted in 0.92 % increment for 3rd maturity level fruit harvested compared to 0.72 % for 1st maturity level harvested fruit. Recommendations related to harvesting were: 1) If the road and truck bin was in bad condition, FFB should be harvested at 1st or 2nd level of maturity; 2) The optimum harvesting-transportation condition for FFB quality was at 1st maturity level in peat land and transported by wood bin truck. While recommendations related to transportation were: 1) The manual loading by throwing to truck bin should be avoided; and 2) In order to maintain FFB quality, loading and transportation delay was better than waiting or queing in oil palm mill.
