This study aims to identify the diversity of weight and size of arbila seeds (Phaseolus lunatus L.) as feed in Amabi Oefeto Subdistrict, Kupang Regency. This research was conducted in Amabi Oefeto Sub-district from October 2020 to February 2021, using field survey methods in 3 villages namely Pathau Village, Muke Village and Oemolo Village. The research variables were 100 dry air weight, 100 dry weight ovens, and arbilla seed size. The results showed that in Amabi Oefeto Subdistrict there are 17 accessions of arbila based on morphological diversity of seeds, with a fresh seed weight of 24.5 grams /100 seeds - 47.5 grams / 100 seeds, dry heavy oven 23 grams/100 seeds - 44.25 grams/100 seeds, 0.06 cm - 0.12 cm, 0.01 cm thick - 0.04 cm, and 0.05 cm - 0.08 cm wide. It is concluded that in Amabi Oefeto sub-district there are 17 accessions of Arbila based on seed morphology. Fresh weight 24.5 grams/100 seeds 47.5 grams/100 seeds, dry oven weight 23 grams/100 seeds up to 44.25 grams/100 seeds, arbillae seed length ranging from 0.06 cm to 0.12 cm, thickness 0.01 cm 0.04 cm, and width 0.05 cm to 0.08 cm, it is recommended to conduct further research on DNA analysis of this accessory to determine the relationship between these accessories.
