Abstract

The aim of this research was to determine the effectiveness of administering betel leaf powder from several types of betel on S. oryzae mortality and determine the best type of betel leaf to use to control S. oryzae. This research method is a single factor Randomized Block Design (RAK) consisting of 6 treatments and 4 replications, so there are 24 experimental units. The treatments tested were K0= control (100 g rice + 10 S.oryzae imago) without the addition of betel leaf powder; S1= Green betel leaf powder; S2= Red betel leaf powder; S3= Black betel leaf powder; S4= Forest betel leaf powder; S5 = Yellow betel leaf powder, each treatment of betel leaf powder consists of (6 g betel leaf powder + 100 g rice + 10 S.oryzae imago). The parameters observed were mortality, percentage of rice damage and efficacy. The results of the study showed that the administration of green, red, black, forest and yellow betel leaf powder had an effect on S.oryzae mortality, the percentage of rice damage and showed high effectiveness (efficacy) values ​​for the use of these insecticides. The lowest percentage of rice damage with black betel leaf powder was 11.04% and the highest S. oryzae mortality was recorded with black betel leaf powder treatment with a value of 92.50% and an efficacy value of 80.50%.

Abstract

This research aims to determine pests in feed corn at several moisture levels in storage warehouses developed in Tirta Jaya Village, Bajuin District, Tanah Laut Regency and PT Arutmin Site Satui, Tanah Bumbu Regency. Sampling at two locations was carried out directly at the farmer's corn storage warehouse and PT Arutmin Site Satui, at the Tirta Jaya Village location 4 kg samples were taken and at the PT Arutmin Site Satui location 3 kg samples were taken, then each sample was weighed weighing 300g each with 3 repetitions, and stored for 1 month. The warehouse pest data obtained will be grouped based on water content, varieties and pests obtained in 1 table. Next, the number of warehouse pest populations is calculated, the population average is calculated, the damage intensity is calculated, the data is tabulated and analyzed descriptively. The observation results showed that the Bisi 2 variety had the highest population of warehouse pests and the intensity of damage with a population of 143 Doloessa viridis, Tribolium sp. 58 individuals, 242 larvae and 11 pupae, with the highest average damage intensity reaching 34.6%. Meanwhile, the warehouse pest population and intensity were the lowest in the RK 457 variety with a total population of Tribolium sp. 8 tails with damage intensity reaching 8%.
