Abstract

The purpose of this research was the Cocoon Production and Viability of Pontoscolex corethrurus Fr. Mull on various concentrations of Sevin insecticide to determine the production and viability of cocoons produced by earthworm Pontoscolex corethrurus Fr. Mull at various concentrations of the insecticide Sevin. This research was conducted from March 2020 to April 2020. The research design used a completely randomized design (RAL) with various concentrations of the insecticide Sevin (0%, 0.1%, 0.2%, 0.3%, 0.4 %, 0.5%) and the data were analyzed using analysis of variance (ANOVA). If there is a significant effect, it is carried out by further testing the Duncan Multiple Range Test (DMNRT) at the level of α = 5%. This research was started from the collection of cow feces from the breeding ground of the Department of Animal Husbandry, Faculty of Agriculture, Indralaya, followed by acclimatization of the earthworms Pontoscolex corethrurus Fr. Mull for 10-15 days in the laboratory, then take the soil and determine the soil water content in accordance with the soil water content at the origin of the earthworm Pontoscolex corethrurus Fr. Mull is taken. Soil water content for earthworm habitats is usually around 30-40%. Observations were made every two weeks for cocoon production and for observation of the viability of the Pontoscolex corethrurus cocoon until it became juvenile. The results of this study showed that the highest number of P. corethrurus cocoons was in the provision of cow feces mixed with 0% Sevin at 3.10 ± 1,17 and the lowest number of cocoons produced in the administration of cow feces that had been mixed with 0.5% Sevin was 0.60 ± 0,50 cocoons/ individual/week compared to other treatments. Hatchability of P. corethrurus cocoons was the highest in the feeding of cow feces mixed with 0% Sevin at 83.87% ± 1,00 and the lowest cocoon hatchability resulted in the administration of cow feces mixed with 0.5% Sevin at 41.67% ± 0,40 compared to Other treatments and based on the results of the ANOVA test data with a confidence level of 95% and Duncan's advanced test (DMNRT) at α = 5%, it can be concluded that the results of research data have a significant effect on cocoon production and viability of earthworm P. corethrurus at various concentrations of the insecticide Sevin.
