The results of the technological assessment of white technical grape varieties growing on the ampelographic collection of the institute are shown: Riesling, Grubella, Goruli mtsvane, No-rock, Khotsa tsibil. Samples of dry white wines were prepared using classical technology. The research was carried out in the laboratory of winemaking technology in micro-winemaking conditions. The weight of one batch of grapes was 7–15 kg. The main physical and chemical parameters of wort and wine were determined. As a result of the organoleptic assessment, con-clusions were drawn about the advisability of using these varieties for the production of natu-ral white table wines. Riesling was chosen as a control variety. Wine materials from the re-searched varieties were distinguished by their typical, pale straw color, with a greenish tint, delicate varietal aroma, full, harmonious taste. This indicates a high potential of the studied varieties for the preparation of high-quality wines.

The results of technological studies of intro-duced wine grape varieties growing on the ampelographic collection of the Institute are shown: Barhatny, Viorica, Golubok, Megra-buer, which are characterized by high sugar accumulation. Liqueur wines were prepared according to the classical technology and the main physical and chemical parameters of the wort and wine were determined. The research was carried out in the laboratory of winemak-ing technology in the conditions of micro-wine production. The weight of one batch of grapes was 10–25 kg. Wine distillate was used as an alcoholic agent. To preserve and enhance the varietal aroma of grapes, the technology of fractional alcoholization was used. As a result of the organoleptic characteristics of liqueur wine samples, preliminary conclusions were made about the feasibility of using the studied varieties for the preparation of liqueur wines. All the studied grape varieties can be recom-mended for the production of liqueur wines.

The paper presents the results of technological evaluation of red wine varieties breeded by All-Russian Research Institute for Viticulture and Winemaking: Vesta, Cherny, Zhemchug, Au-gusta, Teremnoy, Mugofir. These varieties are characterized by high sugar accumulation. Li-queur wines were prepared using classical tech-nology. The research was conducted in the la-boratory of wine technology in micro-wine production. The weight of one batch of grapes was 10–25 kg. The main physical and chemical parameters of wort and wine were determined. Wine distillate was used as an alcoholic agent. For maintaining and enhancing the varietal aroma of grapes we used technology of frac-tional alcoholization. With the help of degusta-tions, organoleptic characteristics of the ob-tained samples of liqueur wines were carried out, as a result of which preliminary conclusions were made about the feasibility of using the studied varieties for the preparation of red li-queur wines. All the studied grape varieties can be recommended for the production of liqueur wines, pink and red.

Haris et al, 2019. The Analysis of Water Suitability for Floating Net Sprouts in Sirah Pulau Padang, Ogan Komering Ilir District, South Sumatra Province. JLSO 8(1):20-30.The purpose of this study is to analyze the level of water suitability of the floating net sprouts in sirah pulau padang, ogan komering river, Serdang Menang Village, OKI South Sumatra Regency based on water physical and chemical parameters. This study was conducted on July - August 2018 at the Komering River, Ulak Jermun village, Terusan Menang Village, and Mangun Jaya Village, OKI District, South Sumatra. The data of sampling was divided into 3 stations, they were; station 1 was Ulak Jermun Village (3 ° 18'45.48 "LS and 104 ° 53'5.32" BT), station 2 was Terusan Menang Village (3 ° 17'14.13 "LS and 104 ° 52'46.78 "BT), and station 3 was Mangun Jaya village (3 ° 18'14.92" LS and 104 ° 52'59.48 "BT). The data of Samples were tested at the chemical laboratory in Palembang Public Water Fisheries and Extension Research Institute directly. The results of the study was for Station 1, Station 2, and Station 3 with a value was  48% with a good feasibility information. The results of measurements of water quality parameters, the pH was about 6.6 - 6.7, temperature was about from 24., 53 - 26.93oC, DO 3.93 - 4.36 mg / l, ammonia was about 0.78 - 0.16 mg / l, water brightness was about from 34.67 - 43.33 cm, CO2 4.53 - 5.03 mg / l, depth 2.36 - 2.47 m, current velocity was about 0.38 - 0.44 m / s, nitrate was about 0.37 - 0.439 mg / l, phosphate was about 0.009 - 0.225 mg / l and the bottom substrate of water was mud.

The present study was conducted in Salt marshes and Salt pans in central parts of Iran. 121 specimens of ants were collected by trapping and hand during spring, summer and autumn 2017 to 2019. Nine species belong to two subfamilies of Myrmicinae and Formicinae were identified. The vegetation, physical and chemical parameters of soil such as salinity, Ph, and other factors were investigated. Darband Shoor Mountain station with five species had the highest diversity and vegetation density and the lowest salinity of soil (72.14 ds/m) whereas Salt Lake station had only one species, with no vegetation and the highest salinity of soil (153.15 ds/m). Cataglyphis lividus (André, 1881) was the dominant species in all the stations except in Darband Shoor Mountain station. All the species were reported for the first time from salt marshes and salt pans in the central parts of Iran and were approved by Prof. Brian Taylor, in Royal Entomological Society of London, England.
