Aktivitas Antijamur Minyak Atsiri terhadap Penyakit Antraknos Buah Pisang di Penyimpanan pada Kondisi Laboratorium

Mizu Istianto, - Eliza

Abstract


ABSTRAK. Antraknos yang disebabkan oleh Colletotrichum sp. merupakan penyakit penting yang menyerang
buah pisang pada penyimpanan. Teknologi yang direkomendasikan untuk mengendalikan penyakit ini adalah dengan
penerapan perlakuan panas dan penggunaan fungisida. Teknologi alternatif yang mempertimbangkan keamanan
konsumen dan lingkungan sangat diperlukan untuk menggantikan penggunaan fungisida. Tujuan penelitian adalah
mengevaluasi aktivitas antijamur beberapa minyak atsiri yang diekstrak dari daun kayu manis, sereh wangi, dan
kulit jeruk besar terhadap penyakit antraknos. Penelitian dilaksanakan di Laboratorium Perlindungan Tanaman Balai
Penelitian Tanaman Buah Tropika pada suhu ruang mulai dari bulan Januari sampai Mei 2007. Hasil penelitian
menunjukkan bahwa minyak atsiri mampu menekan perkembangan miselium jamur Colletotrichum sp.. Minyak
atsiri yang diekstrak dari daun kayu manis mempunyai nilai penghambatan tertinggi (65-72%) terhadap pertumbuhan
miselium Colletotrichum sp., diikuti oleh nilai penghambatan minyak atsiri sereh wangi (62-64%), dan kulit jeruk
besar (14-19%). Hasil ini menunjukkan bahwa minyak atsiri mempunyai potensi yang baik untuk dikembangkan
sebagai teknologi alternatif yang mempertimbangkan keamanan konsumen dan lingkungan

ABSTRACT. Istianto, M. and Eliza. 2009. Antifungal Activity of Essential Oils Against Anthracnose Disease on
Banana Fruit During Storage at Laboratory Conditions. Anthracnose, caused by Colletotrichum sp., is important
disease attacking banana fruit during storage. The technologies recommended to control anthracnose were fungicide
and heat treatment application. Alternative technologies that considered safe to consumer and environment are
needed to replace the use of fungicides. The aim of this experiment was to evaluate antifungal activity of essential
oils extracted from Cinnamomum burmanni, Cymbopogon nardus, and Citrus grandis against anthracnose disease.
The experiment was conducted in the Plant Protection Laboratory of Indonesian Tropical Fruit Research Institute at
room temperature from January to May 2007. The results showed that essential oils was able to suppress the growth
of Colletotrichum sp’s mycelial. Essential oil extracted from C. burmanni had highest inhibition value (65-72%) to
the mycelial growth of Colletotrichum sp., followed by C. nardus (62-64%), and C. grandis (14-19%). This results
indicated that essential oils had good potential to be developed as alternative technology to control anthracnose disease
considering the consumer and environment safety.
