Abstract

Paddy is a rice-producing commodity that is the staple food of the Indonesian people. Paddy is also a strategic commodity that receives priority handling in Indonesia's development. This type of research is quantitative descriptive research. The research was conducted in August 2024 in organic paddy fields in Talang Ubi Utara Village, Penukal Abab Lematang Ilir Regency, South Sumatra. The number of species obtained was 478 of 17 phytophagous species. The results showed that the highest diversity index in the vegetative phase was found in week 6 with a value (H') of 1.795. The value shows that 1<H'<3 medium diversity data. The dominance index of vegetative phase species was found in the 5th week observation which amounted to 0.304. The dominance index value D 0-0.5 is low. The species evenness index in the vegetative phase was highest in the 4th week observation, which amounted to 0.961. The value of E>0.5 is high, in the generative phase is found in week 8 with a value (H') of 2.079. This shows that 1 < H'< 3 medium diversity data. The dominance index of the vegetative phase species is found in the 11th week of observation, which is 0.364. The dominance index value D 0-0.5 is low. The species evenness index in the highest vegetative phase was found in the 10th week observation, which amounted to 0.935. The value of E>0.5 is a high level of evenness of species. It can be concluded that the highest diversity occurred in week 8, the dominance index value in week 11 and the evenness index in week 4.
