Whitefly pest (Bemissia tabacci) is one of the causes of low productivity of cayenne pepper in Indonesian. The use of technology that is still low for whitefly pest control and ineffective monitoring efforts are still obstacles faced by farmers. Incorrect predictions as an effort to control whitefly pests can result in environmental damage due to excessive pestride. Therefore, the prediction of attack rates and production results by utilizing drone imagery technology is expected to be more effective and efficient. The study was aimed at determining the estimated results of damage due to whitefly pests and knowing the correlation of the results of drone image analysis with the results of cayenne pepper crop production in Brejel Lor Hamlet, Pucuk Village. Based on the results of observation and image processing, drone image analysis obtained an accuracy value of y = 1,4669x + 0,1372 R = 0.6, this shows strong accuracy, therefore drone image analysis can detect symptoms of whitefly pest attacks in cayenne pepper plant fields. Analysis of drone imagery of production results also showed a corresponding pattern, high whitefly pest infestation rates gained lower production weight. Environmental factors greatly influence the high and low attack of whitefly pests.

Rice (Oryza sativa) is the main food source in Indonesia. The demand for rice continues to increase with population growth. In 2019, rice production in East Java decreased by 5.50 million tons. The rice production did not meet the national food demand, one of the obstacles to the cultivation of rice is the presence of bacterial blight caused by Xanthomonas oryzae. Bacterial leaf blight is an important disease because it can cause severe damage and can infect the vegetative and generative phases of rice plants. This study was conducted to determine the influence of abiotic environmental factors and distribution patterns of bacterial leaf blight disease through geostatistical approach with variogram and kriging on rice fields with symptoms of bacterial leaf blight disease in Sadang Village, Taman, Sidoarjo. The results of the study for six weeks showed that the distribution of leaf blight bacterial diseases at the study site tended to be high clustered in the north-south direction compared to the east-west direction. The values of the incidence rate at the end of the observation ranged from 20-68% with a pH of about 6-6.9.
