Abstract

The early detection of Fusarium sp. infection in rice seeds is crucial for improving agricultural productivity and food security. Traditional methods like the Blotter Test, while effective, are time-consuming and require specialized personnel. This study explores the potential of thermal imaging technology to detect Fusarium sp. infections on rice seeds quickly and non-destructively. Rice seeds were inoculated with Fusarium sp. and incubated for seven days, during which surface temperatures were measured daily using the Fluke iSee TC01A thermal camera. The results showed that infected seeds exhibited significantly higher surface temperatures compared to control seeds, particularly from days 3 to 6 of incubation. Scatterplot analyses revealed clear temperature differences between infected and uninfected seeds, supporting the hypothesis that thermal imaging can serve as an early indicator of Fusarium infection. The study also demonstrated the high sensitivity and specificity of thermal imaging, particularly on days 2 to 4 of the incubation period. Logistic regression analysis confirmed the significant relationship between seed temperature and infection status, with prediction accuracy up to 91%. This research suggests that thermal imaging technology could replace traditional methods, offering a faster, more efficient approach for seed health monitoring in the agricultural industry.

Abstract

Crystal guava (Psidium guajava) is a superior variety cultivated in Indonesia. A major constraint in crystal guava production is the high incidence of pest attacks, particularly from fruit flies. This study was conducted in a red guava orchard located in Sidoarjo Regency and Jalan Simorejosari A IV/17 during the period from July to August. The research employed a survey method involving the installation of attractant traps and purposive sampling to collect infested fruit for host rearing. Both trapping and host rearing were used to monitor the fruit fly population. Trapping was carried out by installing attractant traps at five predetermined plots, positioned at a height of 1.5 meters and spaced 20 meters apart. Fruit fly rearing involved collecting infested fruit using purposive sampling from the same five plots, then incubating until adult flies emerged. The fruit fly species attacking the red guava orchard was identified as Bactrocera dorsalis. Independent t-test analysis revealed significant differences between the populations of trapped fruit flies and those obtained from host rearing. The emergence rate of fruit fly adults from host rearing exhibited a negative correlation with the trapped fruit fly population, described by the regression equation Y = 359.282 – 7.2146X. Path analysis indicated that rainfall positively correlates with temperature and humidity, while temperature negatively correlates with humidity. Additionally, rainfall and humidity negatively correlate with the trapped fruit fly population, whereas temperature shows a positive correlation.
