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.

This research was conducted to find out how to map the problems in the distribution of social assistance by the DKI Jakarta government. This research uses qualitative research methods based on field studies, which is a research method that is oriented towards primary data collection which is taken through data owned by the DKI Jakarta government and processed using Tableau engine to determine field mapping. The results of this study attempt to provide an overview of the mapping of the distribution of social assistance in cases affected by COVID-19 which uses big data as the database for recipients of the aid. It was found that East Jakarta was an area with several residents who received social assistance due to the impact of the COVID-19 outbreak. This research implies that cooperation, coordination, and harmonization between the central government, regional governments, and private institutions are needed to be right on target, effective and efficient, and supported by a good, integrated, transparent, and accountable system in the distribution of social assistance.

In 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 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.

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.

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.
