Abstract

Mikoriza arbuskula merupakan asosiasi simbiotik yang esensial, antara fungi yang berada pada tanah dengan akar yang diketahui dapat meningkatkan pertumbuhan tanaman inangnya dengan meningkatkan kemampuan penyerapan nutrisi hara, terutama fosfat. Infeksi Mikoriza arbuskula terjadi di dalam organ tanaman dimana simbiosis ini tercipta sebagai akibat perkembangan serempak antara tanaman dan fungi. Dalam fenomena ini fungi mikoriza arbuskula (FMA) menginfeksi dan mengkoloni akar tanpa menimbulkan nekrosis sebagaimana biasa terjadi pada infeksi fungi patogen, dan mendapat pasokan nutrisi secara teratur dari tanaman. Miscanthus sinensis merupakan tanaman pionir yang banyak ditemukan pada daerah kritis yang tersebar luas di daerah Eurasia, termasuk pada daerah lereng pegunungan api di wilayah Jepang. Penelititian ini bertujuan untuk mengkonfirmasi adanya struktur mikoriza pada akar tanaman M. sinensis. Dengan teknik blue staining berhasil mengkonfirmasi bahwa FMA memainkan peranan penting dalam pertumbuhan dan resiliensi tanaman yang hidup pada daerah kritis seperti pada lereng pegunungan api.

Abstract

Lake Rawa Pening, in Indonesia, is one of the super lakes of revitalization priority. The factor that causes Lake Rawa Pening to become a priority lake is high sedimentation, which is triggered by the expansion of land cover such as settlement, agriculture, and industry in the Rawa Pening Catchment Area. This study examines changes in water quality parameters in Rawa Pening Lake from remote sensing data with Google Earth Engine (GEE). The physical parameters used to assess water quality are the concentration of Total Suspended Solid (TSS) and the area of water vegetation (water hyacinth). The results indicate that the water quality of Rawa lake has changed in the TSS level and the distribution area of aquatic vegetation. In general, from 2017, 2019 and 2021 there were fluctuations in the percentage of water hyacinth and TSS. Modeling results indicate that Lake Rawa Pening is mostly hypereutrophic.
