Authors: Subandi Yeyen , Qodir Zuly , Jubba Hasse , Nurmandi Achmad 
Published: April 2021

Abstract
Special Region of Yogyakarta (DIY) is a sultanate area led by a king or sultan. In the government, the sultan is the governor, whose duty is a lifetime. Regarding clientelism brokers, the emergence of patronage and political patronage practices still occurs in the government system of kingdom territory. Yogyakarta is known as the city of education and culture. Besides, Yogyakarta has a legendary community organization since the 1985s with its strength and power both in social and political as clientelism brokers. The organization is Joxzin (Jogjakarta Islamic Never Die). Joxzin always supports the legislative candidates or the president promoted by Partai Persatuan Pembangunan (PPP). Their support in the 2019 general election parliamentary candidates succeeded in making the candidate be the Regional Representative Council of the City of Yogyakarta (DPRD Yogyakarta). Joxzin, with its power, could appoint Anang to become the Chairperson of PPP’s Party Branch Development Board in Yogyakarta (DPC PPP Yogyakarta). The two examples refute the majority of previous research, whereas previous studies found that the client’s position was weak, and their resources were below the patron’s. However, the research done by the Joxzin’s client showed that Joxzin had resources above the patron represented by PPP. This research is important because of the era of big data in the 4.0 industrial revolution, AI as a search tool assisted by using the Nvivo 12 Plus analysis tool. In this study, the authors applied Social Network Analysis (SNA) with the assistance of the NVivo 12 Plus analysis tool to see the Joxzin social network as a mass organization and also the clientelism broker practice that was carried out by Joxzin in the 2019 elections with PPP. From the NVivo 12 Plus analysis, the results of the clientelism variable obtained several indicators. They are as a messenger, economic benefits, buying and selling votes, reciprocation, and a political party agent with the 2019 election. The five indicators are not all the same as the results of studies or research done by other experts.

Published: April 2021

AbstractIn this paper, the flexural behaviour of under-reinforced M70 grade basalt FRP rebar concrete beams in terms of first crack load, pre-cracking and post-cracking behavior, deflection pattern, crack development pattern and ultimate load carrying capacity is evaluated. Loads at first crack in basalt FRP rebars beams are higher than the normal steel rebar concrete beams confirming that basalt FRP rebars beams offer greater resistance to cracking. The ultimate flexural strength of basalt FRP rebar concrete beams have improved when compared to normal steel rebar concrete beams. First crack formation was delayed in basalt FRP rebar concrete beams due to which fatigue strength is increased which in turn increases the time taken for first crack occurrence and thereby increasing the load carrying capacity. The deflection at the mid span decreased in basalt FRP rebar concrete beams which indicates the improved flexural stiffness of the elements thereby reducing the structural member’s deformability, increasing strength and hence controlling deflection. Mid-span deflections at peak load reduced in basalt FRP rebar concrete beams. The ultimate deflection in case of basalt FRP rebar concrete beams is less than that of normal steel rebar concrete beams.
An Optimization of Bitmap Index Compression Technique in Bulk Data Movement Infrastructure
Authors: Kumar Manoj , Gupta Tarun Kumar , Sarwe Deepak Umrao 
Published: April 2021

AbstractAn index is an optional structure, associated with a table or clustered table that can sometimes speed up data access. By creating an index on one or more columns of a table, you gain the ability, in some cases, to retrieve a small set of randomly distributed rows from the table. This research aims to free the filled disk space after documents have been erased. We verify the current compression technologies and apply the data pump to the bitmap index compression. Bitmap is more effective for minimal unique value, according to the traditional wisdom index. However, it needs no Bitmap index at high cardinality or low cardinality by data pump. In this paper we recommend a pump function for space release in the database after documentation has been removed. This utility does not free disk space even though the elimination of records from the table is seen by the Bitmap Index. To free up the room and adjust the index point position, we have introduced data pump for compression. The data pump is commonly used in oracle database for logical backups. Finally, we study the bitmap index which is widely used for industrial purposes and address unanswered questions for the future.

Published: April 2021

Abstract
The use of stainless-steel results in significant life-cycling cost savings. It likewise has high-temperature properties, just as satisfactory weldability, and fracture toughness. This study investigates the behaviour ofstainless-steel plate girder under simultaneous bending and shear using commercial FE software Abaqus. For modelling stainless steel of grade Duplex EN 1.4462 (2205) was used, which possess twice the design strength of austenitic and ferritic stainless steels. Numerically validated models were used to conduct parametric study covering effect of flange slenderness and flange thickness to web thickness ratios. The results show a significant contribution of the flange on shear strength and bending moment capacity of stainless-steel plate girders. The contribution of the flange was also influenced by the presence of end rigid post and change in the panel aspect ratio.

Abstract
The construction industry consumes a huge amount of concrete due to fast urbanization and an increase in the construction field is depleting the resources of natural sand and M sand at a high rate of concern hence leading to various problems in the environment. Besides that, cementitious material in concrete releases a large amount of CO2 into atmosphere. Similarly cost of concrete is attributed to the cost of its ingredients. The concept of using eco-friendly materials in concrete enhances scope for green concrete which utilizes many kinds of industrial by-products thus resulting in the use of substitute materials which are economical in concrete production. This has attracted the attention of investigators to look out for new replacements for fine aggregate and cement. At this degree, copper slag, which is an industrial by-product produced while smelting and refining copper may be a partial alternative for fine aggregate and GGBS, a by-product of steel manufacturing industry can effectively replace cement with better durable concrete mix. Thereafter, an attempt has been made to control the cost of cement and sand with concrete blend of grade M25&M30 through methodical evaluation of physical, mechanical and chemical properties in the present work. Series of concrete mixtures are prepared with a constant 40% copper slag substituting fine aggregate and GBBS replaces cement at 0%, to 50% with5% increment. The results suggest that copper slag and GGBS can replace fine aggregate and cement in reinforced cement concrete, without compromising on the quality, thereby contributing to the effort of environment friendly building materials with economic benefits, which is the need of the hour.

Evaluation of tribological characteristics of natural garlic oil as an additive in rubber seed oil
Authors: Jesbin K S , Mahipal D 
Published: April 2021

Abstract
Industrial oils have the essential elements of a lubricant, but their environmental feasibility and economic effect are insufficient. Vegetable oils are emerging as an alternative to industrial lubricants. The production of oil from energy resources, such as vegetable seed oils, is important. Rubber seed oil has been shown to be of greater value among the base stock of bio lubricants, since it contains large concentrations of unsaturated fatty acids. The effectiveness of natural garlic oil as an additive in rubber seed oil in enhancing the tribological characteristics of steel/steel contact is conducted in this research. The findings are compared with SAE20W40 oil data. Friction and wear experiments were carried out using a four-ball tribotesting machine. Additive added rubber seed oil offered low friction values compared to mineral oil. The newly produced oil was tested by a kinematic viscometer. Improvement in the viscosity index was demonstrated by additive added rubber seed oil.
Comparative fluidity study of AA7075 unreinforced alloy and Al2O3 reinforced composite
Authors: Roshitha P A , Arun M S 
Published: April 2021

Abstract
Aluminium alloys are used extensively in the automobile and aerospace areas. The reason behind this is the high strength to weight ratio of aluminium and its alloys. As requirement for better materials arose, the existing aluminium alloys evolved into composite forms. Composites can enhance the mechanical properties of the metal matrix. The property which gets improved depends upon the reinforcement. But the problem associated with composites is their poor fluidity. There are only a handful of researches conducted to evaluate the effects of reinforcing agents on composite fluidity. Fluidity is expressed in terms of fluidity length or flow length. It is defined as the maximum length the molten metal will flow in a long channel before solidifying. In this work, the fluidity characteristics of AA7075 alloy and AA7075 alloy reinforced with aluminium oxide (Al2O3) are explored. It was found that the fluidity length of aluminium alloy AA7075 decreased by almost 20 cm on addition of the reinforcing agent, aluminium oxide. This may be due to the tendency of alumina particles to cluster together or accumulate in the aluminium matrix. This increases the viscosity and thereby reduces the fluidity length.

Published: April 2021

Abstract
Conventional synthetic materials in engineering applications are imprinting our ecosystem with non-biodegradable wastes. Environmental awareness throughout the world has influenced materials design and selection, which is leading to orientation from synthetic to biodegradable materials. Efforts are put to improve the properties of existing natural materials for engineering applications. In this study hemp fabric was subjected to alkalization, maleic anhydride treatment and cryogenic treatment, to improve the fabric’s physiochemical properties. Differential scanning calorimetry (DSC), Thermo gravimetric analysis (TGA), and Differential Thermo gravimetric Analysis (DTG) were used to investigate the changes in thermal behaviour of untreated and treated fabric. Physical properties such as functional groups of fabrics were studied and compared with Fourier Transform Infrared Spectroscopy (FTIR). Alkalization and maleic anhydride treatment on fabric have substantially increased the number of hydrogen bonding in cellulose, which lead to increase in stiffness of the fabric. Thermal stability of hemp fabric has increased significantly with cryogenic treatment. An increase in the cellulose composition after the cryogenic treatment shows better physical properties. These observations give hemp fibbers wide range of opportunity to be part of engineering applications with thermal stability, stiffness, and eco-friendly requirements.

Published: April 2021

Abstract
Thermal energy management is fetching more importance, recently in many sectors including chemical/petrochemical, automotive, aerospace, and electronics. An attempt has been done on the investigation in thermal energy storage (TES) applications using phase change composites. To make the composite material suitable for potential devices the thermal conductivity should be high. For achieving this, fillers with higher thermal conductivity can be incorporated into polymers to form polymer composites. In the light of background study on the recent researches in this area, nanocomposites are expected to show good thermal conductivity behavior. In this work, ZnS/PMMA nanocomposites are used as the conductive polymer for thermal energy storage in which the ZnS nanoparticles are used as the fillers. The solution casting method is used to prepare the nanocomposites. Samples based on the weight percentage of filler are used for characterization. The thermal stability and conductivity of the composite material are evaluated using TGA and Thermal Conductivity Apparatus. The SEM analysis of ZnS particles shows the nanoscale size and morphology suitable for filler components. An enhancement of 72% in thermal conductivity is noted for the 6% (ZnS) sample with PMMA.

Published: April 2021

Abstract
Nanoemulsions are emulsions having droplet sizes in the nanometre range. Nano emulsions have unique properties such as robust stability, transparent nature, high surface area, and tunable rheology. The present study focuses on the synthesis of sesame oil-based nanoemulsion using ultrasonic emulsification to break down particle size to nanometric range. The method uses small surfactant concentration and low energy to synthesize homogenous nanoemulsion. The emulsion is stabilized using Tween 20 surfactant. Aqueous nanoemulsion samples were prepared using sesame oil by varying the surfactant concentration to determine the most stable composition, and different properties of each sample prepared, were analyzed. The ultrasonication time was also varied to study the impact of sonication time. Nanoemulsions formed were then evaluated for their various properties. The droplet size and zeta potential for all samples were determined by the Dynamic Light Scattering technique wherein the best nanometer size distribution was found to be at 1:3 (oil: surfactant) composition. The physical stability was determined using a centrifuge at 3000 rpm. Conductivity, pH, and density of the samples were then measured. A polydispersity index of 0.514 was obtained for the sample of oil: surfactant ratio 1:3. Fourier Transform Infrared Spectroscopy studies were conducted for all samples.

Abstract
Aqueous two-phase extraction is an ecologically safe method for heavy metal recovery and regeneration from contaminated aqueous solutions. Investigation has been carried out experimentally for the extraction of lead from aqueous solutions using Polyethylene Glycol 1500-Ammonium sulfate two-phase system. The extracting agent used is sodium chloride. Aqueous two-phase extraction experiments for Pb(II) have been performed in batch mode according to the central composite design under Response Surface Methodology. The effect of independent parameters as to the extractant concentration, initial salt solution pH, and initial salt phase metal concentration on the extraction efficiency has been studied experimentally. The results indicate that all the three independent parameters studied have significant effect on extraction efficiency. A second-order polynomial model has been used to fit the dependent variable in the experimental range of parameters. The maximum extraction efficiency obtained from the model is about 51% atinitial salt solution pH of 2.8, NaCl concentration of 49.9mmol/Land initial salt phaselead concentration of 9.8 mg/L. This is in agreement with the results obtained from the experiment conducted at optimum conditions.

Published: April 2021

Abstract
Wastewater treatment is an energy-intensive process. During secondary wastewater treatment, unwanted characteristics like Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD) etc. are reduced to permissible levels with the help of bacteria as this is a microbe driven process. A novel method of cultivating Oxygenic Photo Granules (OPGs) which are natural aggregates predominantly consisting of cyanobacteria from the activated sludge and using it to treat the wastewater in the secondary treatment is under development. After the primary treatment, OPGs help to substitute the high energy-consuming aeration equipment which deems the secondary process more sustainable. Cultivation of OPGs is influenced by many factors including the intensity of light used during cultivation, the concentration of sludge etc. Manipulating these factors, we can cultivate OPGs in the most efficient way possible. The objective of this work is the optimization of the time constraints for developing OPG samples, then analyze the energy saving of this process at a pilot scale. OPGs substitute the aeration equipment in the secondary treatment process, and they are mix evenly with the wastewater to be treated in a sequential batch reactor. Upon continuous stirring followed by settling and decanting, the wastewater is treated and analyzed. Utilization of OPGs in wastewater treatment not only saves energy but is also efficient than the conventional method, thereby making this process a more economical option.
