Abstract
Praktek budidaya kopi telah bergeser dari sistem naungan tradisional (tumpangsari) ke sistem intensif (monokultur) mulai tahun 1970-an. Sistem pertanian monokultur mengakibatkan hilangnya tutupan kanopi berharga yang ditemukan di perkebunan kopi tumpangsari. Perkebunan kopi tumpangsari memiliki kompleksitas struktural tinggi yang menawarkan tempat tinggal bagi berbagai macam organisme. Organisme yang dapat terganggu habitatnya adalah agens hayati yang berperan dalam mengendalikan hama tanaman yaitu jamur entomopatogen. Sistem tanam mempengaruhi kondisi rizosfer sehingga berdampak pada keberadaan jamur entomopatogen. Analisis keanekaragaman jamur entomopatogen pada rizosfer berbagai sistem tanam kopi perlu dilakukan dengan tujuan informasi hasil penelitian ini dapat menjadi tumpuan penerapan sistem pertanian yang berkelanjutan. Penelitian ini dilaksanakan pada bulan April 2021 hingga Juli 2021 di Laboratorium Pengendalian Hayati, Jurusan Hama dan Penyakit Tumbuhan, Fakultas Pertanian, Universitas Brawijaya Malang. Pelaksanaan Penelitian terdiri dari pengambilan sampel tanah pada lokasi, isolasi, perhitungan keanekaragaman, purifikasi dari hasil isolasi dan pembuatan preparat jamur untuk selanjutnya dapat diidentifikasi secara mikroskopis. Tujuan dari penelitian ini untuk mengetahui keanekaragaman jamur entomopatogen pada rizosfer kopi monokultur dan tumpangsari kopi - kacang tanah. Sebanyak 5 genus jamur entomopatogen ditemukan pada rizosfer monokultur kopi dan tumpangsari kopi - kacang tanah: Aspergillus, Fusarium, Mortierella, Metarhizium, dan Penicillium. Genus Metarhizium hanya ditemukan pada lahan monokultur, sedangkan genus Penicillium hanya diperoleh pada lahan tumpangsari. Indeks keanekaagaman Shannon (H’) jamur entomopatogen dari rizosfer tumpangsari lebih tinggi (1,39) dibandingkan monokultur (0,95). Analisis keanekaragaman jamur entomopatogen menunjukkan bahwa sistem tanam berpengaruh sama terhadap kekayaan genus, namun berpengaruh berbeda dalam kelimpahan individu. Sistem tanam tumpangsari perlu diterapkan karena memiliki kompleksitas tinggi menyediakan tempat tinggal bagi jamur entomopatogen.
English Abstract
Coffee cultivation has shifted from a traditional shade system (intercropping) to an intensive system (monoculture) starting in the 1970s. Monoculture farming systems result in the loss of valuable canopy cover found in intercropping coffee plantations. Intercropping coffee plantations have a high structural complexity that offers a habitat for a wide variety of organisms. Organisms that can be disturbed by their habitat are biological agents that play a role in controlling plant pests, namely entomopathogenic fungi. Planting systems that affect the rhizosphere conditions that have an impact on the presence of entomopathogenic fungi. Analysis of the diversity of entomopathogenic fungi in the rhizosphere of various coffee growing systems needs to be carried out with the aim that the information from this research can be used as a basis for implementing sustainable agricultural systems.. This research was conducted from April 2021 to July 2021 at the Biological Control Laboratory, Department of Pests and Plant Diseases, Faculty of Agriculture, Universitas Brawijaya Malang. The implementation of the research consisted of taking soil samples at the site, isolation, calculating diversity, purification of the isolation results and making fungal preparations to be further identified microscopically. The purpose of this study was to determine the diversity of entomopathogenic fungi in the rhizosphere of monoculture and intercropping land use. A total of 5 genera of entomopathogenic fungi were found in the rhizosphere of coffee monoculture and coffee-peanut intercropping: Aspergillus, Fusarium, Mortierella, Metarhizium, and Penicillium. The genus Metarhizium was only found on monoculture land, while the genus Penicillium was only found on intercropping land. The Shannon diversity index (H') of entomopathogenic fungi from intercropping rhizosphere was higher (1.39) than monoculture (0.95). Analysis of the diversity of entomopathogenic fungi showed that the cropping system had the same effect on genus richness, but had a different effect on individual abundance. The intercropping system needs to be applied because it has a high complexity that offers a place to live for entomopathogenic fungi.
