Abstract

PBRM (Plant Beneficial Rhizospheric Microorganism) is a microbe that is able to form colonies in plant roots (rhizosphere) that have the ability to fix nitrogen (N), and dissolve potassium (K), phosphorus (P), and zinc (Zn). Increasing NUE can increase plant growth through various mechanisms. Population and dynamics of rhizosphere microorganisms are different from other soil microorganisms, this is caused by an increase. The purpose of this study was to determine the type of rhizosphere bacteria that can be as PBRM. The method used The research was conducted at the Microbiology Laboratory of the Faculty of Agriculture, Brawijaya University, Malang. The characterization process was carried out in UB's microbiology laboratory. 50 grams of soil for planting corn were put into an erlenmeyer containing 500 ml NB (for bacteria) and 500 ml liquid PDA (for mold) and then incubated with the secretary for about 24 hours and then diluted in series to a dilution rate of 10-3,10-4,10 -5. Then from the dilution factor of 10-3,10-4,10-5 0.1 ml is taken and inoculated in solid media by the pour plate method. The results showed that the antagonistic rhizosphere bacteria were P. fluorescens, B. subtillis, and Rhizobium sp.

Abstract

Purpose of this study is to determine the anatomical differences of transport tissue (xylem and phloem) in Carica papaya L. Roots, which grown on contaminated and uncontaminated Al (Aluminum). The study was carried out by digging 0-30 cm of soil to take 3 lateral roots, then cut transversely, stained using xylol and observed the transport tissue using a computer binocular microscope with a magnification of 100x. Based on the research, it is known that the xylem and phloem of transport tissue obtained from the roots of Carica papaya L. which grows on soil contaminated with aluminum slag ash has differences with the root transport tissue of Carica papaya L. which grows on soil without aluminum slag ash contamination.

Abstract

The Dem River, originating from the Coban Glothak Waterfall, is an important water source for local communities. However, the rapid growth of tourism in the Coban Glothak area raises concerns regarding potential water pollution. To evaluate the river’s ecological condition, this study analyzed biological, physical, and chemical parameters with a focus on epilithic diatoms as bioindicators. An exploratory design was applied across three representative stations, each subdivided into three sampling points. Biological analysis involved measuring abundance, diversity, and dominance of diatoms using PAST software. Physical and chemical parameters included temperature, pH, total dissolved solids (TDS), dissolved oxygen (DO), biological oxygen demand (BOD), chemical oxygen demand (COD), nitrate (NO₃), and phosphate (PO₄). Results showed that epilithic diatom abundance was relatively high at all stations, but a decreasing trend was observed from station 1 to station 3, reflecting spatial variations in environmental conditions. The diversity index consistently exceeded 1.5, indicating a fairly diverse diatom community and suggesting supportive water conditions for aquatic organisms. Low dominance values at all stations revealed no species over-dominance, reflecting balanced ecological conditions. Furthermore, the physical and chemical measurements aligned with class 2 and 3 water quality standards, confirming that the Dem River remains suitable for sustaining aquatic life with reasonable diversity.
