Keanekaragaman Cacing Tanah Pada Tanah Residu Pestisida di Kabupaten Lombok Barat, Nusa Tenggara Barat

Abstract

The use of pesticides on agricultural land is intended to maintain production and repel agricultural pests of vegetable crops (mustard). However, the lack of knowledge about the impacts and dangers caused by the use of pesticides on agricultural land causes the application of pesticides to be excessive and not in accordance with predetermined doses. So that it can interfere with the survival of organisms in the vicinity. One of the organisms that is directly affected by the impact of pesticide residues is earthworms. This research aims to analyze the density of earthworms on vegetable (mustard) farms exposed to pesticides in Bug-bug Hamlet, Lingsar District – West Lombok Regency. This type of research is a quantitative descriptive research. Retrieval of research data will later be carried out by describing and identifying research results in the form of data and tables. The results of this study indicate that five types of earthworms were found on vegetable (mustard) farms, namely: species Lumbricus rubellus, Lumbricus terrestis, Phontoscolex corethrurus, Perionyx excavatus and Eisenia foetida. Earthworm densities on agricultural land were Lumbricus rubellus (0.28) and Lumbricus terrestis (0.142) and Pontoscolex sp. (0.28), Perionyx excavatus (0.142), and Eisenia foetida (0.142).
