%X Cassava (Manihot esculenta Crantz) dijadikan sebagai makanan terpenting ketiga di  dunia dan sumber pendapatan di beberapa negara. Produksi cassava di Provinsi  Lampung mengalami penurunan dari tahun 2015 sampai tahun 2019 yang  menunjukkan bahwa terdapat permasalahan pada usaha tani cassava antara lain  penyakit layu fusarium yang disebabkan oleh jamur Fusarium oxysporum (Fo).  Penggunaan komponen penyeleksi pada medium tanam secara in vivo seperti asam  salisilat lebih efektif dan efisien dalam menangani penyakit layu fusarium.    Mekanisme ketahanan melalui jalur asam salisilat berhubungan dengan protein-  protein yang terkait dengan patogenesis (pathogenesis-related proteins/PR proteins)    seperti kitinase, peroksidase, β- glukanase dan PR-1. Tujuan penelitian ini untuk  mengetahui (1) aktivitas enzim peroksidase pada tanaman cassava hasil pengimbasan  asam salisilat, (2) kandungan karbohidrat pada tanaman cassava hasil pengimbasan  asam salisilat. 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. Data yang dihasilkan kemudian dianalisis  menggunakan Analysis of Variance (ANOVA) dan dilakukan uji lanjut dengan Uji  Beda Nyata Jujur (BNJ) pada taraf 5%. Hasil penelitian menunjukkan bahwa pada  konsentrasi asam salisilat 100 ppm menghasilkan aktivitas enzim peroksidase  tertinggi yaitu 0,193 U/mg/menit dan kandungan karbohidrat tertinggi yaitu 0,194  mg/g jaringan.

Cassava production in  Lampung Province experienced a decline from 2015 to 2019, which shows that  there are problems in cassava farming, including fusarium wilt disease caused by  the fungus Fusarium oxysporum (Fo). The use of selector components in the in  vivo growing medium such as salicylic acid is more effective and efficient in  treating fusarium wilt disease. The resistance mechanism through the salicylic  acid pathway is related to pathogenesis-related proteins (PR proteins) such as  chitinase, peroxidase, β-glucanase and PR-1. The aim of this research was to  determine (1) the activity of the peroxidase enzyme in cassava plants resulting  from exposure to salicylic acid, (2) the carbohydrate content in cassava plants  resulting from exposure to salicylic acid. 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. The  resulting data was then analyzed using Analysis of Variance (ANOVA) and  further tested using the Honestly Significant Difference Test (BNJ) at the 5%  level. The research results showed that a salicylic acid concentration of 100 ppm  produced the highest peroxidase enzyme activity, namely 0.193 U/mg/minute  and the highest carbohydrate content, namely 0.194 mg/g tissue.
