Abstract. Global climate change triggered the heavy and extreme rainfall in forms of intensity, pattern, duration, amount, and frequency. This condition strongly influences the occurrence of soil erosion, especially in the humid tropic region. The purpose of this research is to analyse the soil erosion rate under pineapple cultivation in Central Lampung, Indonesia. The results show rainfall erosivity using Bols equation is around 2109-3211 metric ton/h/ha. Soil erodibility is ranging 0.007-0.080 was categorized low to very low due to the amount of sand and silt is too low. The Slope also categorized low around 1-4%. The crop factor value is around 0.01-1. The rate of erosion in pineapple was 2016 is 1.51 ton/ha/year until 15 on/ha/year; that value is under standard permissible erosion (18.5-25 ton/ ha/ year).
