Rizki, Awanda Zidni (2018) Uji Komparatif Efek Fungisida Dari Beberapa Ekstrak Tumbuhan Terhadap Jamur Patogen Colletotrichum Gloeosporides Pada Cabai Rawit (Capsicum Frutescens L.). Sarjana thesis, Universitas Brawijaya.
Abstract
Cabai rawit (Capsicum frutescens L.) merupakan salah satu komoditas hortikultura yang sangat berpotensi untuk dikembangkan, hal ini disebabkan cabai rawit memiliki nilai ekonomi yang tinggi dan berpotensi untuk dijadikan komoditas ekspor. Salah satu faktor yang menyebabkan penurunan produktivitas cabai ialah hama dan penyakit tumbuhan seperti penyakit Antraknosa yang disebabkan oleh jamur patogen Colletrotichum gloeosporioides. Selama ini petani di Indonesia menggunakan fungisida kimia untuk mengendalikan penyakit tersebut. Namun penggunaan penggunaan fungisida kimia dapat berdampak buruk terhadap lingkungan. Cara alternatif yang bersifat ramah lingkungan ialah menggunakan fungisida nabati dari bunga cengkeh, biji adas, sereh wangi, daun selasih, dan daun kemangi. Penelitian ini bertujuan mengetahui pengaruh kelima ekstrak nabati terhadap penghambatan pertumbuhan dan perbedaan efektivitas penghambatan dari kelima ekstrak nabati tersebut terhadap pertumbuhan jamur patogen patogen C. gloeosporioides secara in-vitro dan in-vivo. Penelitian dilaksanakan pada bulan bulan Mei 2018 sampai dengan bulan September 2018 di Laboratorium Toksikologi, Laboratorium Penyakit Tumbuhan, Jurusahan Hama Penyakit Tumbuhan, Fakultas Pertanian, dan Laboratorium Keamanan Hasil Pangan (KHP), Fakultas Perikanan, Universitas Brawijaya Malang. Penelitian terdiri dari percobaan melihat kemampuan beberapa ekstrak nabati untuk menekan pertumbuhan jamur patogen Colletrotichum gloesporides secara in-vitro dan in-vivo. Data dianalisi menggunakan anova dan diuji lanjut menggunakan DMRT pada taraf kesalahan 5%. Hasil penelitian Ekstrak nabati dari bunga cengkeh, biji adas, sereh wangi, daun selasih, dan daun kemangi dapat mempengaruhi penghambatan pertumbuhan jamur patogen C. gloeosporioides secara in-vitro dan in-vivo. Penggunaan ekstrak dari daun kemangi pada uji in-vitro menunjukan keefektivitas dalam menekan pertumbuhan miselium jamur patogen C. gloeosporioides sebesar 4,14%, dan pada uji in-vivo menunjukan keefektivitas ekstrak nabati dalam menghambat pertumbuhan diameter bercak jamur patogen C. gloeosporioides sebesar 0,075%
English Abstract
Chili pepper (Capsicum frutescens L.) is one of the horticultural commodities that has the high potential to be developed. This is because chili pepper has higher economic value and higher probability to be an export commodity. The consumption of chili pepper from year to year keeps on increasing. One of the factors that causes the depression of chili pepper's productivity are pests and plant diseases such as Anthracnose which is caused by Colletrotichum gloeosporioides, an pathogenical fungi. During this time farmers in Indonesia often using chemical fungicides to controk disease. However, use a Chemical fungicides can have negative impact on the environment. An alternative way that is more environmentally friendly is by using the biofungicides from the the extract of cloves, fennel seeds, citronella, clove basil leaves, and sweet basil leave. This study aims to determine the effect of the five biofungicides on growth inhibition and the difference in inhibitory effectiveness of the five plant extracts on the growth of pathogenic fungi pathogenic C. gloeosporioides in in-vitro and in-vivo. This research was held in May 2018 to September 2018 in Toxicology Laboratory, Plant Diseases Laboratory, Department of Pests and Plant Diseases, Faculty of Agriculture, and Food Security Laboratory, Faculty of Fisheries and Marine Science, Brawijaya University. This research consists in-vitro and in-vivo experiments to see the effectiveness of some of the plant-based extracts to suppress the growth of Colletrotichum gloesporides. The data was analyzed using anova and was examined further using DMRT at the level of error of 5%. Research results Vegetable extracts from clove flowers, fennel seeds, fragrant lemongrass, basil leaves, and basil leaves can influence the inhibition of the growth of pathogenic fungi C. gloeosporioides in in-vitro and in-vivo. The use of extract from basil leaves in the in-vitro test showed the effectiveness in suppressing the growth of pathogenic fungal mycelium C. gloeosporioides by 4.14%, and in in-vivo tests showing the effectiveness of vegetable extracts in inhibiting the growth of pathogenic fungi C. gloeosporioides by 0.075%.
