Isolation of Yeasts from Sugarcane Stems and Their Identification Based on Internal Transcribed Spacer Sequences ABSTRACTFermentative yeasts used in food, health, and energy industries need to be explored to discover their potential. The purpose of this study was to obtain fermentative yeast isolates from sugarcane stems and subsequently to undertake morphological, biochemical, and molecular identification. The isolation of epiphytic and endophytic yeasts was carried out by spread plate method using sugarcane soak water and sugarcane juice on potato dextrose agar (PDA) and yeast-glucose-peptone (YGP) agar media. Morphological identification was based on macroscopic and microscopic observations. Biochemical identification was performed using carbohydrate fermentation and 50%-glucose media tests. Selected isolates were identified molecularly using Internal Transcribed Spacer (ITS). Seven yeast isolates were obtained, of which isolate Ed 1B was selected. Isolate ED 1B was of round colonies, creamy white colour, shiny, embossed, and wavy appearance, ovoid cell shape with a cell diameter of 4.74 µm. It had budding cells, was able to ferment glucose and sucrose (but not lactose), and grew on 50 %-glucose media. Results of BLAST showed that isolates Ed 1B had 99% homology with Kodamaea ohmeri.Keywords: isolation, ITS, molecular identification, Saccharum officinarum L., yeast ABSTRAKKhamir fermentatif yang digunakan dalam industri pangan, kesehatan dan energi perlu dieksplorasi untuk mengetahui potensinya.

Published: August 2019

Para perancang struktur kapal dapat menentukan jarak gading yang optimal dengan batasan resiko tekuk pada pelat. Penelitian ini dilakukan untuk mengetahui beban batas lateral pada masing-masing jarak gading sehingga dapat diketahui resiko tekuk yang terjadi pada pelat. Tekuk adalah suatu ragam kegagalan yang diakibatkan oleh ketidakstabilan suatu elemen struktur yang diepengaruhi oleh aksi beban. Kegagalan yang diakibatkan oleh ketidakstabilan dapat terjadi pada berbagai material. Pada saat tekuk terjadi, taraf gaya internal dapat sangat rendah. Fenomena tekuk berkaitan dengan kekakuan elemen struktur. Kekuatan tekuk pada setiap bagian struktur dapat dievalusi dengan menggunakan konsep tegangan tekuk kritis. Besarnya tegangan tekuk kritis berhubungan dengan persamaan klasik tekuk Euler dan bergantung pada apakah tekuk ini terjadi pada kondisi elastis dan tidak elastis. Penurunan beban berbanding terbalik dengan kenaikan jarak gading,semakin jauh jarak gading maka semakin kecil beban yang dibutuhkan agar pelat mengalami tekuk.

Published: August 2019

Minyak nilam dapat diperoleh dengan menyuling atau mengekstraksi daun nilam kering. Metode penyulingan daun nilam ada 3 metode yaitu penyulingan dengan air, penyulingan dengan uap, penyulingan dengan uap dan air. Dari ketiga metode penyulingan tersebut yang paling banyak menghasilkan minyak adalah metode penyulingan dengan uap. Akan tetapi metode penyulingan dengan uap ini tidak bisa digunakan apabila untuk menghasilkan minyak bunga-bungaan. Karena bunga tersebut akan mengumpal sehingga minyak yang akan ada pada bunga tersebut tidak larut dalam alkohol dan sukar menguap bila dibandingkan minyak atsiri lainnya.Dengan alasan inilah minyak nilam banyak sekali dipakai sebagai bahan baku dalam industri parfum. Selain itu minyak nilam juga bersifat fiksatif dan sifat fiksatif inilah tidak dapat digantikan oleh minyak apapun. Sehingga sangat bagus apabila digunakan sebagai bahan baku dalam industri parfum.Dari penelitian yang telah dilakukan maka dapat dilihat bahwa hanya dengan komposisi yang hanya sedikit minyak nilam tersebut mampu mengikat aroma dari bunga-bungaan sehingga dapat bertahan lama. Dari angket dapat diketahui bahwa baik pria maupun wanita menyukai aroma parfum dari campuran minyak tanaman dan minyak bunga-bungaan tersebut. Kata Kunci : minyak nilam, parfum, penyulingan

Published: August 2019

The relevance and feasibility of extracting residual gas from depleted gas deposits is shown. The possible directions of the extraction of residual gas from depleted gas deposits by its displacement from a porous medium of non-hydrocarbon gases are characterized. The use of nitrogen to displace natural gas from a porous medium has been substantiated. Using the GEM compositional modeling module, which is included in the licensed computer program CMG (Computer Modeling Group), studies were made of the effect of the pressure of the start of injection of nitrogen into the reservoir and the duration of its injection period on the gas recovery coefficient for residual gau. The study was conducted for deposits of square and round shape. The research results are presented in the form of graphical dependencies of the current reservoir pressure, nitrogen content in borehole products and gas recovery coefficient for residual gas from the pressure of the start of injection of nitrogen into the reservoir and the duration of the period of its injection. Using the results of the research, the optimal values ​​of the parameters of the process of injecting nitrogen into the exhausted gas deposits of square and round forms and the corresponding values ​​of the gas recovery coefficient were established. For the considered deposits of square and rounded forms, they are 0.29 Рin and 14.8 months, 0.31 Рin and 12.9 months, respectively. At the time of reaching the volumetric nitrogen content in the producing gas of 5 %, the gas recovery coefficient for residual gas for a square-shaped deposit is 83.91 %, for a round-shaped deposit – 77.49 %. The physical nature of the process of displacing residual gas with nitrogen from depleted gas deposits of square and round forms is characterized.
ABOUT CHANGE OF THE LEVEL OF OIL IN THE STORAGE FLOATING-ROOF TANKTHROUGH ATMOSPHERIC BURNERS
Authors: Lisafin V. P. , Liuta N. V. 
Published: August 2019

The authors analyze the main tendencies in the reconstruction and development of tank farms of the main oil transportation system in Ukraine, namely the use of large-volume tanks with a floating roof. The authors consider one of the reasons that can complicate the operation of such tanks that is the presence of liquid (in the form of rain) or solid (snow and ice) atmospheric precipitation on it, which leads to the additional immersion of the floating roof of the tank into oil. The literature on the exploitation of floating roof tanks has been analyzed and it is found out that there are practically no data of measurements on the basis of which it is possible to estimate the influence of liquid atmospheric precipitation on the depth of immersion of tank floating roofs. The article shows the topicality of the issue from the point of view of commodity-transport operations on oil metering. The authors show the results of measuring the oil levels in the tank with regular appliances in the presence and absence of rainwater on the floating roof (after drainage of the latter through the drainage system) and the results of their treatment in order to determine the difference in the accounted oil mass in the tank caused by the accumulation of water on the roof, taking into account oil physical properties and the data of processing of the gauge tables of the tank. The results of natural measurements are analyzed and a simplified method of calculating the depth of immersion of a roof in the presence of additional loads on it in the form of atmospheric precipitation is developed. The oil level in the tank was determined using a standard system of the ENRAF type, and the determination of oil volumes was done using the gauge table of the tank. Based on physical regularities, the authors derive theoretical dependencies to determine the amount of atmospheric moisture on the floating roof depending on the volume (changes of the oil levels) of water on it. It is shown how to calculate the minimum amount of atmospheric water on the roof, which leads to the need to introduce corrections while determining the mass of oil in the tank using a static volume-mass method. This research has proved the necessity of introducing corrections while determining the level of oil in the tanks with floating roofs when there is atmospheric precipitation on the roof.
