The effect of Papaya leaf Powder in Seed Storage and its Impact on the Viability of Black Soybeans of the Detam-1 variety Led to the Establishment of the Callosobruchus analis F.

Black soybeans are one of the soybean varieties that have black skin and have various ingredients that provide many benefits for the human body. The shrinking of soybean seeds causes a decrease in the quality and quantity of seeds which can result in reduced supply of seeds for seeding purposes during the storage process. One of the factors that affect the viability of seeds during storage is the attack of warehouse pest insects, so it is necessary to control using vegetable insecticides by utilizing papaya leaf powder. This study aims to study the development of C. analis F. beetles due to the application of papaya leaf powder in seed storage and its effect on the viability of black soybeans of the Detam-1 variety. This experiment was carried out at the Basic Laboratory of the Faculty of Winaya Mukti University from June to August 2023. Environmental Design uses Complete Randomized Design consisting of 6 treatments and 4 repeats. Treatment dose of papaya leaf powder per 100 g black soybeans, namely: A = 0 g; B = 1 g; C = 2 g; D = 3 g; E = 4 g and F = 5 g. The results showed that the dose of papaya leaf powder 3 g per 100 g black soybeans seeds had an effect on the development of C. analis F beetles (mortality, number of eggs, number of larvae, number of pupae and number of imago), percentage of seed damage and percentage of seed weight, but did not affect the viability of black soybean seeds of the Detam-1 variety..
