%T DETEKSI TANAMAN CASSAVA (Manihot esculenta Crantz) TAHAN
Fusarium oxysporum BERDASARKAN KANDUNGAN GULA REDUKSI,
VOLUME AKAR, DAN RASIO PUCUK AKAR HASIL PENGIMBASAN
ASAM SALISILAT
%X Cassava (Manihot esculenta Crantz) merupakan tanaman penting di Indonesia sebagai sumber
karbohidrat. Cassava sering kali mendapat gangguan patogen salah satunya yaitu penyakit layu
fusarium. Pengendalian penyakit layu fusarium dapat dilakukan dengan penggunaan kultivar
unggul yang resisten melalui pengimbasan asam salisilat. Tujuan penelitian ini adalah
menganalisis kandungan gula reduksi tanaman cassava hasil induced resistance dengan asam
salisilat serta mengetahui volume akar dan rasio pucuk pada tanaman cassava tahan Fusarium
oxysporum hasil pengimbasan asam salisilat dibandingkan kontrol. Penelitian ini
menggunakan Rancangan Acak Lengkap (RAL) dengan satu faktor, yaitu penambahan asam
salisilat dengan konsentrasi 0 ppm, 80 ppm, 100 ppm, 120 ppm, dan 140 ppm. Tiap konsentrasi
dilakukan pengulangan sebanyak 5 kali, dan pada setiap ulangan terdiri dari 1 tanaman cassava.
Data penelitian berupa data kualitatif dan data kuantitatif. Data kualitatif disajikan dalam
bentuk deskriptif komparatif yang didukung dengan foto sedangkan data kuantitatif dianalisis
menggunakan Statistical Package for the Social Sciens (SPSS) dengan metode Analysis of
Variance (ANOVA). Apabila terdapat beda nyata dilakukan dengan lanjut dengan Uji Beda
Nyata Jujur (BNJ) pada taraf 5%. Hasil penelitian menunjukkan bahwa terjadi peningkatan
kandungan gula reduksi pada tanaman cassava (Manihot esculenta Crantz) seiring dengan
meningkatnya konsentrasi asam salisilat serta diketahui konsentrasi 100 ppm berpengaruh
paling baik pada volume akar dan rasio akar pucuk pada tanaman cassava (Manihot esculenta
Crantz) tahan Fusarium oxysporum.

Cassava (Manihot esculenta Crantz) is an important plant in Indonesia as a source of
carbohydrates. Cassava is often attacked by pathogens, one of which is fusarium wilt.
Control of fusarium wilt disease can be done by using superior cultivars that are
resistant through the use of salicylic acid. The aim of this research was to analyze the
reducing sugar content of cassava plants resulting from induced resistance with
salicylic acid and to determine the root volume and shoot ratio in Fusarium oxysporum
resistant cassava plants resulting from exposure to salicylic acid compared to control.
This research used a Completely Randomized Design (CRD) with one factor, namely
the addition of salicylic acid with concentrations of 0 ppm, 80 ppm, 100 ppm, 120 ppm
and 140 ppm. Each concentration was repeated 5 times, and each repetition consisted
of 1 cassava plant. Research data consists of qualitative data and quantitative data.
Qualitative data is presented in comparative descriptive form supported by photos,
while quantitative data is analyzed using the Statistical Package for the Social Sciences
(SPSS) with the Analysis of Variance (ANOVA) method. If there is a significant
difference, it is carried out by continuing with the Honestly Significant Difference Test
(BNJ) at the 5% level. The results of the research showed that there was an increase in
the reducing sugar content in cassava plants (Manihot esculenta Crantz) along with
increasing concentrations of salicylic acid and it was found that a concentration of 100
ppm had the best effect on root volume and shoot root ratio in Fusarium oxysporum
resistant cassava (Manihot esculenta Crantz) plants.
