Abstract: 
Cassava (Manihot esculenta Crantz) is an important food commodity in Indonesia, and in the future this commodity will play an increasingly strategic role in people's lives and the country's economy. But until now there are still many obstacles, one of which is fusarium wilt disease. Fusarium wilt disease can be controlled by using superior cultivars that are resistant to the disease, by applying salicylic acid. The aim of this study was to analyze the protein profile and reducing sugar content in cassava plants after being induced with salicylic acid and compare them with controls. This research used a Completely Randomized Design (CRD) with one factor, namely the addition of salicylic acid consisting of 5 concentration levels, namely 0 ppm, 80 ppm, 100 ppm, 120 ppm, and 140 ppm. Each concentration was repeated 5 times. This research data is in the form of qualitative data and quantitative data. Qualitative data is presented in comparative descriptive form and presented in the form of photographs. Quantitative data was tabulated with different concentration factors and analyzed using Analysis of Variance then further tested with the Honestly Significant Difference Test (BNJ) at the 5% level. The research results showed that there was a missing protein band, namely a band at a molecular weight of 115, and there was also the appearance of a new band, namely a molecular weight of 85 kDa, as well as an increase in the reducing sugar content in cassava plants along with increasing salicylic acid concentrations.
