An arthropod is one of the critical animal groups in the agriculture ecosystem. The purpose of this research is to determine the effect of botanical insecticide mixed with formulation from Piper aduncum fruit and Tephrosia vogelii leaf as well as their application intensity against the diversity of soil arthropods. The research was conducted in cabbage plantation regularly applied with pesticide using Randomized Block Design two factorial with 5 treatments and 3 duplications in three regions (Jorong Jambu Kaniki, Batipuh Atas, and Tanah Datar) from March to July 2017. The treatments included control, WP (wettable powder) botanical insecticide formulation, EC (Emulsifiable concentrate) botanical insecticides formulation, BT (Bacillus thuringiensis) formulation, and synthetic insecticide (chlorfenapyr). Soil arthropod samples were taken by pitfall trap at 75 points representing all treatments. The type of formulations and intensity of application affect the number of soil arthropods individuals. There is an interaction between formulations and intensity of application, enhancement on formulations application of WP, and EC tend to increase the number of soil arthropods individual. Otherwise, the use of synthetic insecticide significantly decreases the number of soil arthropod individuals. The application intensity did not affect the type of soil arthropods. Further identification of soil arthropod samples from the experimental field showed the diversity of soil arthropods is categorized as moderate (2,23–2,97), evenness is categorized medium to high (0,25-0,65), index similarity formulations are categorized high (0,923- 1,000), and index similarity intensity application in categorizing medium to high (0,667-1,000). Soil arthropods ware found in cabbage plantations consist of 3 classes: Arachnida (1 Order; 1 Family), Insecta (1 Order; 4 Family), Entoghnata (1 Order; 2 Family). Order Collembola, Family Onychiuridae dominated soil arthropods.
