      Abstract
      Rhizoctonia sp. merupakan salah satu cendawan patogen yang sering menyebabkan kerusakan tanaman di persemaian dimana penyebarannya sangat luas. Pengendalian hayati yang ramah lingkungan merupakan salah satu solusi untuk menekan penyebarannya. Minyak atsiri memiliki kandungan bahan aktif sebagai alternatif mengurangi ketergantungan kimia sintetik yang kurang ramah lingkungan. Penelitian ini bertujuan untuk menganalisis pengaruh minyak atsiri kunyit dalam menghambat pertumbuhan patogen Rhizoctonia sp. secara in vitro. Penelitian ini menggunakan metode pemberian minyak atsiri kunyit dengan beberapa konsentrasi yaitu 1%,5%,10% dan kontrol pada media PDA dan PDB. Pengamatan selanjutnya dilakukan secara makroskopis dan mikroskopis. Hasil penelitian menunjukkan bahwa nilai hambat tertinggi terdapat pada perlakuan kunyit 10%. Efektivitas pengendalian patogen Rhizoctonia sp. dipengaruhi oleh tingkat konsentrasi dan kandungan bahan aktif dalam minyak atsiri.
       
      Rhizoctonia sp. is one of the pathogenic fungi that often cause damage to plants in nurseries, where its spread is widespread. Environmentally friendly biological control is needed. Essential oils contain active ingredients as an alternative to reduce dependence on less environmentally friendly synthetic chemicals. This study aimed to analyze the effect of turmeric essential oil in the growth of Rhizoctonia sp. pathogen in vitro. The study applied turmeric essential oil at various concentrations, namely 1%, 5%, 10%, and a control, on PDA and PDB media, followed by macroscopic observations. The results showed that the highest controlling value was observed in the 10% turmeric concentration on both PDA and PDB media. The results of the study indicated that the highest inhibitory effect is observed in the 10% turmeric treatment. The effectiveness of controlling the Rhizoctonia sp. pathogen was influenced by the concentration level and active ingredients present in the essential oil.
