In the Podillya area, the most promising for greening different objects is the Lupine perennis L. and Lupine Polyphyllus Lindl. For creation of modern garden compositions of the park zone of Vinnytsia National Agrarian University the most appropriate are the varieties: Lulu-Russell, Minaret, Albus, Fireworks, which were well adapted to the growing conditions, were practically not affected by pests and diseases, were sufficiently resistant to environmental conditions. According to the flowering phase study, it was found that the highest flowering duration was observed in perennial lupine plants. In determining the suitability of the plants studied by us for their use in landscaping, their assessment of the complex of economic and biological indicators in accordance with the State Methodology of Variety Testing was carried out. Their high score on a set of criteria testifies to the prospect and suitability for cultivation in Podillia conditions, as well as the value for different uses: flower beds, ridges, mixboards, landscape type compositions and their smaller variants imitating natural groups.

Coliform bacteria is a one of a kind negative bacteria that is commonly found marine waters, the presence of coliform bacteria can be an indicator of biology that is important to know the environmental conditions. This study aims to determine the environmental conditions based on biological indicators in the form of an abundance of coliform bacteria in the waters of the River right District Labuhanbatu Selatan. The main ingredient in this study is the River right and sediment. The results of the analysis showed the density of coliform bacteria in the study site ranged from 500-700 colonies/ml for the sample waters and 27-120 MPN/g for sediment samples. The results obtained are still below the quality standard so that the river right in good condition biologically. The presence of coliform bacteria in the river can affect human and biota. So it needs to be considered in the efforts of the management of the coastal environment, particularly in efforts to maintain the sustainability of fisheries resources

Abstract Water quality monitoring is a key component in the management of these important water resources and ecosystems. Biological indicators can be monitored continuously and are easy instructions for monitoring the occurrence of pollution. One of the biological parameters that can be used as a marker of environmental conditions is plankton. zooplankton can be used as study material to determine the quality and water productivity. The method used in this research is descriptive to determine the water quality condition in the estuary of the Kalimireng river biologically through the identification and characterization of zooplankton. Observations of plankton identification, plankton abundance, dominance index, and characterization of zooplankton were analyzed by fluorescence microscope observation. Three species of zooplankton were found in the waters of the Kalimireng estuary, Leptodiaptomus sp., Canthocamptus staphylinus, and Diaphanosoma bracyurum. Zooplankton is more abundant in water conditions at high tide compared to water conditions at low tide. At high tide, the highest abundance value was obtained at the station I at week 3, 843 ind/mL. At low tide, the highest abundance value was obtained at the station I at week 2,251 ind/L. The highest Dominance Index (D) at tidal water conditions is shown at station 2. This indicates that there is a community that dominates at that station.

In recent years, with electron microscopes coming into wider use, their installation environments do not necessarily give their performance full play. Their environmental conditions include air-conditioners, magnetic fields, and vibrations. We report a jointly developed entirely new vibration isolator which is effective against the vibrations transmitted from the floor.Conventionally, large-sized vibration isolators which need the digging of a pit have been used. These vibration isolators, however, are large present problems of installation and maintenance because of their large-size.Thus, we intended to make a vibration isolator which1) eliminates the need for changing the installation room2) eliminates the need of maintenance and3) are compact in size and easily installable.
