Published: June 2020

Abstract
Energy consumption of mobile application software is an important factor influencing the battery life of smart phone terminals. Currently, for the tens of thousands of Android software, we propose a static visual detection and classification method based on application energy consumption. Compared with the high-precision and complex application component energy consumption model, this model analyzes the bytecode images generated by the dex and xml files in the Android apk and trains them with deep learning methods. The energy consumption level of two kinds of different mobile terminal software can be obtained, which can quickly estimate the energy consumption of mobile terminal when the application is runing. Experimental results show that the model’s classification accuracy of energy consumption estimation is 50.49%, which can help mobile end users to easily predict the battery power consumed by applications.

Published: June 2020

Abstract
The operation with pressure is to carry out the lifting and lowering of the tubing or oil rod without releasing the pressure. Compared with traditional downhole operation, the operation with pressure can ensure the upward and downward of the string without pressure relief. The effective plugging of the inside of the oil pipe and the annulus of the oil jacket is the main characteristic of the operation under pressure. When the tubing is lifted, the interior of the tubing is sealed and blocked due to the downhole pressure, it will generate upward force on the tubing, which will make it difficult to run the tubing. The project uses a down-pressure device to assist the down-flow of the tubing. If the down-pressure is too large, buckling instability occurs, which increases the construction difficulty for the down-run operation. Combining elasto-plastic mechanics buckling instability theory and finite element simulation method to study the compression stability of tubing under pressure. The variation law of critical buckling force of tubing diameter, length and wall thickness under pressure is analyzed by numerical model, which provides the basis for equipment design and process plan formulation.

Published: June 2020

Abstract
The reservoirs rocks of natural bitumen deposits of the Lower Permian system and the Kazanian stage of the Tatarstan territory are considered. The relationship of groundwater composition in bitumen reservoirs with lithologic features of water-saturated rocks is shown. Rocks compositions contribute to formation of three water classes in oil deposits: hydrocarbonate, sulfate and chloride. Hydrocarbonate waters lie over erosion downcutting of rivers in the most elevated territory part. Their origin is associated with hydrolysis and carbon-dioxide leaching of the Permian terrigenous rocks. Inland waters of hydrocarbonate-sodium (soda) composition of bitumen deposits are located above local drainage basis. They are formed as a result of sulfate reduction processes in deposits. The inland waters of sulfate composition of calcium and sodium groups are characteristic of deposits located below the drainage basis. Their origin is associated with dissolution of gypsum and anhydrites, as well as with ion exchange reactions between the calcium of the solution and the sodium which absorbed by rock complex. Chloride waters associated within the eastern side of the Melekess Depression, where there is an active hydrodynamic relationship between the Permian system aquifers and chloride-calcium salt brines of the Carboniferous rocks. The nature of the distribution and presence of aquifers in deposits is determined by the lithological features of reservoir formation.

The use of modified polyurethane foam adsorbents for mercury adsorption applications can reduce the impact of mercury pollution. This study aims to study the characteristics of adsorbents made from castor oil, MDI (Methylene diphenyl diisocyanate), glycerol, distilled water and modified by the addition of zeolite and bentonite. Polyurethane foam which has optimum performance is further characterized to determine physical and chemical properties, including: functional groups (FTIR), morphology (SEM) and area (BET). The results of FTIR Characterization showed that in polyurethane foams without modification there was a C = O group which is a typical group in the polyurethane group shown in wavenumber (1654-1516 cm−1, 1680-1514 cm−1, and 1593-1516 cm−1) Whereas in zeolite modified polyurethane foam there is a C = CH group with a wavenumber of 3008 cm−1 which is a typical group for zeolite whereas in bentonite there is a C = CH group with a wavenumber of 3007 cm−1 which is a typical group for bentonite. The results of SEM characterization show that zeolite modified polyurethane foam has a smooth and flat structure with small pores and polyurethane foam with bentonite has irregular or irregular particle shape. The average BET area obtained in the PUF modification is 1.3778 m2 g−1. Whereas for the smallest BET area obtained at synthetic PUF 19.1 gr + Zeolite 40% for 0.773 m2 g−1, the area is influenced by the comparison of composition from polyurethane foam synthesis.

Authors: Awaluddin A , Amiruddin E , Anggraini R , Indriyani N , Siregar SS 
Published: June 2020

Abstract
The pristine cryptomelane (OMS-2) and Fe-OMS-2 (1%, 5%, and 10%) have been successfully synthesized by a one-step sol-gel method and characterized by XRD, SEM, BET surface area and AAS. The incorporation of Fe (III) within the structure of OMS-2 leads to an increase in surface area, pore-volume, and catalytic activity for the degradation of methylene blue (MB) and a decrease in the content of K+ and average of pore diameter. The catalytic test indicated that the catalytic activity of Fe-OMS-2 1% is considerably higher that of pure OMS-2. The highest degradation of MB is 93.5% achieved using Fe-OMS-2 1% after 120 minutes of degradation time, the initial concentration of MB of 20 ppm, the catalyst concentration of 0.125 mg and the H2O2 volume of 15 mL. The enhanced catalytic activities of Fe-OMS-2 compared to pristine OMS-2 for catalytic degradation of MB are associated with an increase in surface area, pore-volume, and smaller particle size. The results from catalytic studies imply that the metal doping is an effective strategy to enhance the catalytic activities of OMS-2 for degradation of MB.

Abstract
The pipes for land or sea are generally made of carbon steel and susceptible to corrosion. Cathodic protection can be used to control metal corrosion in water and soil. Cathodic protection is a metal surface protection system bypassing adequate direct current to the metal surface and converting sacrificial anode area on the metal surface into cathodic region. The aim of this research was to study the effect of cathodic protection in controlling the corrosion rate of carbon steel and determine the best immersing time for sacrificial anode in 25,000 ppm sodium chloride solution to protect the cathode. Zinc was used as the sacrificial anodes for the cathodic protection. Then, the effect of immersion time (10, 20, and 30 days) and distance of the anode from the cathode (1, 2, and 3 cm) were investigated. The best protection for corrosion was obtained at immersion time of 10 days and electrode distance of 1 cm, allowing corrosion rate of 0.694 mpy with an efficiency of 81.8%.

Some modification on membrane composition and structure is conducted to improve membrane filtration performance and mitigate fouling phenomena. Fouling on membrane surfaces lead to decrease permeabilty, increase energy consumtion, and shorten membrane life time. The aim of this study is to manufacture PES membrane which involved inorganic additives consits of Carbon and Fe2O3particles to mitigate fouling tendency. All of membranes were prepared using phase inversion method with dissolving PES polymer into dimethyl formamide (DMF). The result membranes were characterized using Scanning Electron Microscopy (SEM) to investigate morphological structure and breaking strength to determine mechanical property. Membrane filtration performance were tested using soy protein solution in cross-flow system. The results showed that the addition of inorganic particles in PES membrane caused the increasing of pores which lead to increase pure water flux from 15.14 L/m2.h to 58.67 L/m2.h. Fouling mitigation test towards soy protein also showed that carbon and Fe2O3particles enhanced membrane flux recovery ratio from 64.5 to 76%. Furthermore, the inorganic particles presence in PES membrane also improved the tensile strength of membrane up to 128 Mpa.

Published: June 2020

Abstract
Efforts to deal with waste using the adsorption method showed effective results. However, it was discussed of the sorbent after the remediation process is cumbersome. An alternative to overcome this problem can be done by fixing the adsorbent into a solid form consisting of a porous polymer without changing its chemical affinity with metal ions. In this study, the adsorbent used was bioelastomeric containing activated charcoal from palm shell waste and elastomeric, which would then be contacted with Hg2+ metal ions. The process variable in this study was the composition of heavy metal Hg2+ 8, 12, 16, 20, and 24 mg/L with the contact time until it reached equilibrium. Based on the calculation, the palm shell bioelastomeric used three adsorption isotherm models, Freundlich isotherm (R2 = 0.991), Langmuir isotherm (R2 = 0.967) and Dubinin-Radushkevich isotherm (R2 = 0,871). The results showed that the efficiency of adsorption of heavy metal Hg2+ with bioelastomeric palm shell was almost close to 100%. In conclusion, palm shell bioelastomeric can be a potential adsorbent with a high heavy metal removal ability.
