JURNAL AGRONOMI TANAMAN TROPIKA (JUATIKA)JURNAL AGRONOMI TANAMAN TROPIKA (JUATIKA)

The disease that causes low chili productivity in Indonesia is anthracnose, anthracnose disease caused by the fungus Colletotrichum spp. Efforts to control anthracnose disease are currently still being made using many synthetic pesticides. The use of synthetic pesticides can have a negative impact on the environment. Vegetable functions can be used as another effort to control anthracnose. Plant extracts can be used in anthracnose disease control are Senduduk leaf extracts. This study aims to obtain the concentration of Senduduk plant leaf extract (Melastoma malabathricum L) in inhibiting the growth of Colletotrichum spp. Research is carried out in the field and laboratory. The design used in this research was a complete randomized design (RAL) with 5 treatments of Senduduk leaf extract, namely K0 = 0%, K1 = 3%, K2 = 6%, K3 = 9%, and K4 = 12%. With 3 repetitions. The results showed that Senduduk leaf extract treatment with a concentration of 12% effective could inhibit the growth of Colletotrichum capsici fungus.

The research concluded that anthracnose disease in chili plantations in Rambah Baru Village is caused by Colletotrichum capsici.Senduduk plant leaf extract possesses the ability to inhibit the growth of the Colletotrichum capsici fungus, which is responsible for anthracnose disease.Specifically, a concentration of 12% Senduduk leaf extract demonstrates effectiveness in inhibiting the growth of this fungus.

Penelitian lebih lanjut perlu dilakukan untuk mengidentifikasi senyawa kimia spesifik dalam ekstrak daun senduduk yang bertanggung jawab atas aktivitas anti-fungsinya, sehingga dapat dimaksimalkan efektivitasnya sebagai agen pengendali hayati. Selain itu, studi perlu dilakukan untuk menguji efektivitas ekstrak daun senduduk dalam kombinasi dengan agen pengendali hayati lainnya, seperti mikroorganisme antagonis, untuk mencapai pengendalian penyakit yang lebih komprehensif dan berkelanjutan. Terakhir, penelitian lanjutan dapat difokuskan pada pengembangan formulasi ekstrak daun senduduk yang stabil dan mudah diaplikasikan di lapangan, termasuk mempertimbangkan penggunaan bahan pembawa alami untuk meningkatkan daya rekat dan penetrasi ekstrak ke dalam jaringan tanaman, serta menguji efektivitasnya pada varietas cabai yang berbeda dan kondisi lingkungan yang beragam.
