Abstract

Glyphosate and paraquat are broad-spectrum herbicides that commonly used in rice fields to control weeds. This study aims to isolate and identificate bacteria from rhizosphere of rice plants which resistant to glyphosate and paraquat herbicides. Thirty bacterial isolates were isolated from rhizosphere of rice plants and screened for their resistance of glyphosate and paraquat herbicides. One isolate was resistant to 4,000 ppm of glyphosate and 1,600 ppm of paraquat. Based on Biolog omniLog identification system, isolate 4.2 was identified as Ensifer meliloti.Keywords: bacteria, herbicide, resistant, rhizosphere  ABSTRAKGlifosat dan paraquat adalah herbisida berspektrum luas yang biasanya digunakan untuk mengendalikan gulma. Penelitian ini bertujuan untuk mengisolasi dan mengidentifikasi bakteri dari rizosfer padi sawah yang resisten terhadap herbisida glifosat dan paraquat. Tiga puluh isolat bakteri telah diisolasi dari rizosfer padi sawah dan diseleksi resistensinya terhadap herbisida glifosat dan paraquat. Terdapat satu isolat yang resisten terhadap 4.000 ppm glifosat dan 1.600 ppm paraquat. Berdasarkan sistem identifikasi Biolog omniLog, isolat 4,2 merupakan Ensifer meliloti.Kata kunci: bakteri, herbisida, resisten, rizosfer

Abstract

A sketch is a simple drawing or rough draft that depicts the main parts without details. A sketch drawing is an initial idea drawing to express certain ideas into a design drawing summarizing aspects of the initial drawing design that require further processing. Sketch drawing is basically drawing lines with a free hand, without the help of a ruler. In drawing this sketch, sometimes the lines produced on the object edges are not very bright, and require sharpening on each edge of the object. For this reason, sharpening is also done on the edges of the object to make it look sharper on the edges of the object. This image sharpening is useful so that it can be interpreted by the human eye. In the process of working on this thesis, the software used is MATLAB. MATLAB is one of the software with a high level programming language. The final result of this thesis is an object with sharpened edges. In the thesis work using the Haar Wavelet method.
