Ferdiantino., Yehuda and Dr. Ir. Mintarto Martosudiro,, MS. (2024) Keragaman Jamur Rhizosfer pada Tanaman Sawi (Brassica juncea L.) di Lahan Organik dan Konvensional. Sarjana thesis, Universitas Brawijaya.
Abstract
Sawi merupakan tanaman hortikultura yang populer, bernilai ekonomis, dan kandungan tinggi. Perbedaan praktik budidaya pada lahan organik dan konvensional dapat memengaruhi produktivitas sawi. Adanya perbedaan input di lahan juga berpengaruh terhadap kelimpahan dan keanekaragaman jamur rhizosfer. Jamur rhizosfer adalah mikroorganisme yang hidup di sekitar akar tanaman dan dapat meningkatkan pertumbuhan akar. Keragaman dan kelimpahan jamur rhizosfer pada pertanian organik dan konvensional penting diteliti karena dapat memengaruhi ekologi tanah, kesehatan tanaman, dan kualitas hasil panen. Penelitian tentang keragaman maupun kelimpahan jamur rhizosfer pada tanaman sawi yang dibudidayakan di lahan organik dan konvensional diharapkan dapat memberikan wawasan pengetahuan yang lebih baik mengenai bagaimana lingkungan maupun praktik budidaya dapat mempengaruhi pertumbuhan tanaman terkait komposisi dan keragaman jamur rhizosfer, serta potensi kesehatan tanaman sawi. Penelitian dilaksanakan pada bulan September 2023 hingga Desember 2023 di Laboratorium Hama Penyakit Tanaman Pangan dan Hortikultura di Pandaan, Pasuruan. Pengambilan sampel tanah di 2 daerah yaitu Kecamatan Trawas, Kabupaten Mojokerto, Jawa Timur (lahan organik) dan Kecamatan Pacet, Kabupaten Mojokerto, Jawa Timur (lahan konvensional). Penelitian menggunakan metode survei, eksplorasi, komparasi, dan wawancara. Pengamatan jamur rhizosfer dilakukan secara makroskopis dan mikroskopis. Data hasil eksplorasi dilakukan analisis dengan indeks keanekaragaman (H’) dan dominasi (C). Hasil penelitian menunjukkan bahwa nilai keanekaragaman jamur rhizosfer di lahan organik (H’ = 2,03) lebih tinggi dibandingkan keanekaragaman jamur rhizosfer di lahan konvensional (H’ = 1,63). Sedangkan nilai dominasi jamur rhizosfer di lahan organik (C = 0,16) lebih rendah daripada nilai dominasi jamur rhizosfer di lahan konvensional (C = 0,22). Kedua jenis lahan tergolong keanekaragaman yang sedang dengan tidak ada jenis yang mendominasi. Selain itu, hasil eksplorasi jamur rhizosfer yang ditemukan di lahan organik terdapat 12 koloni diantaranya adalah genus Trichoderma sp., Aspergillus sp., Penicillium sp., Talaromyces sp., Rhizopus sp. dan Curvularia sp. Sedangkan di lahan konvensional terdapat 24 koloni diantaranya adalah genus Trichoderma sp., Aspergillus sp., dan Penicillium sp. Selain itu, terdapat amur rhizosfer yang tidak dapat teridentifikasi berjumlah 1 jenis di lahan organik dan 1 jenis di lahan konvensional.
English Abstract
Mustard greens are a popular horticultural crop, have economic value and high content. Differences in cultivation practices on organic and conventional land can influence mustard greens productivity. The differences in inputs on land also influence the abundance and diversity of rhizosphere fungi. Rhizosphere fungi are microorganisms that live around plant roots and can increase root growth. The diversity and abundance of rhizosphere fungi in organic and conventional agriculture is important to research because it can influence soil ecology, plant health and crop quality. Research on the diversity and abundance of rhizosphere fungi in mustard plants cultivated on organic and conventional land is expected to provide better insight into how the environment and cultivation practices can influence plant growth related to the composition and diversity of rhizosphere fungi, as well as the health potential of mustard plants. The research was carried out from September 2023 to December 2023 at the Pest and Disease Laboratory of Food Crops and Horticulture in Pandaan, Pasuruan. Soil samples were taken in 2 areas, namely Trawas District, Mojokerto Regency, East Java (organic land) and Pacet District, Mojokerto Regency, East Java (conventional land). The research used survey, exploration, comparison and interview methods. Observations of rhizosphere fungi were carried out macroscopically and microscopically. The results of data exploration were analyzed using diversity (H') and dominance (C) indices. The research results showed that the diversity value of rhizosphere fungi in organic land (H' = 2.03) was higher than the diversity of rhizosphere fungi in conventional land (H' = 1.63). Meanwhile, the dominance value of rhizosphere fungi in organic land (C = 0.16) was lower than the dominance value of rhizosphere fungi in conventional land (C = 0.22). Both types of land are classified as medium diversity with no one type dominating. Apart from that, the results of exploration of rhizosphere fungi found in organic fields contained 24 colonies including the genus Trichoderma sp., Aspergillus sp., Penicillium sp., Talaromyces sp., Rhizopus sp. and Curvularia sp. Meanwhile, in conventional land there are 12 colonies, including the genus Trichoderma sp., Aspergillus sp., and Penicillium sp. In addition, there are rhizosphere amurs that cannot be identified, amounting to 1 type on organic land and 1 type on conventional land.
