The low-quality fruitset of oil palm fresh fruit bunch (FFB) has occurred in 2014 in the acid sulphate soil of PT Kalimantan Sawit Abadi, Central Kalimantan. It was known that the FFB quality has a very low percentage of fruitset about 17.4% on January 2014. The objective is to examine the historical quality of oil palm FFB fruitset for more than eight years (2014 – 2022) on acid sulphate soil and the factors that influenced it. Routine observations were conducted monthly with the variables fruitset value, number of male inflorescence anthesis (MI), and population of Elaeidobius kamerunicus. The data was carried out in a historical descriptive analysis (paired T comparison test). For eight years, the trend of fruitset quality in the observation sites has increased. The fruitset value on September 2022 reached 57% and was significantly different compared to 2014. It was known that the population of E. kamerunicus/ha significantly increased in the same period. The number of MI/ha each year tends to decrease (R2 = 0.151) with changes in plant age, ie. 5 – 13 years. Plant age development had a strong Pearson correlation (0.945) with the FFB quality.
