This study aims to analyze the economic factors of management on company performance of the Regional Public Company (PERUMDA) Drinking Water in Jambi Province. Determination and selection of this research sample using purposive sampling technique using certain criteria. The selection criteria consisted of PERUMDAM (public regional drinking water company) in Jambi Province, PERUMDAM which had consecutive financial data for the 2016-2020 period. The sample of this research is 9 PERUMDAM in Jambi Province. Data analysis was performed using quantitative descriptive statistics and observations. The analysis used is Multiple Regression Analysis of Panel Data with the help of Eviews Software, The results of the study explain that based on the results of the Multiple Regression Analysis of Panel Data, it shows that economic factors that affect PERUMDAM's business management in Jambi Province, Market Share and Employe Cost has a negative significant effect on PERUMDAM's Business Management in Jambi Province, Water Selling Price, Number of Customer and General Adminitration Cost has a positive and significant effect on PERUMDAM Business Management in Jambi Province 09 30 2022 45 53 CC BY-NC-ND 4.0 10.35940/BEIESP.CrossMarkPolicy www.ijrte.org true 10.35940/ijrte.C7254.0911322 https://www.ijrte.org/portfolio-item/c72540911322/ Department of Quantity Surveying, Akanu Ibiam Federal Polytechnic, Unwana Afikpo, Ebonyi State.

Nigeria road pavement is subjected to have low road density of 23km/m2 of the pave land area and justification for this material stress, functional disability and loss of cohesion. In Ebonyi state there is needs to assess the impact of failed road pavement on economic growth and social stability of the state. Most of the state urban roads failed because of many vehicles passing in definite section of the road per unit time at any suitable period, subjecting the paved areas into physically disintegration of crystalline aggregated material informed of ruttings, pothole, raveling and cracks and some deteriorate or decomposed in a large number of cement aggregate into organic matter causing chemical separations and moisture attack on the paved area by attacking the fabric bond of the binding pavement. The aim of this research is to analyze roads pavement failures for effective cost management. The research design comprised extensive literature. This research was to facilitate the measurement of variables on affected areas causing surface depression and surface deterioration on large number of aggregated crystalline material from rehabilitation of the respective road projects. The research was design to measure stress types, stress values, stress seventy and stress density derive from affected paved area. The data collected were presented in tables, percentage, and pie chart and analyzed with multiple regressions. The findings will establish the state of stress over strain will be sustainable for road pavement in urban areas. The model implies based on the data collected the cause of stress values in urban roads increase by 0.284 (28.4%) were trigger increase in road rehabilitation, repairs and remedial works by 0.77, 0.31 and 0.60 and which were ascertain the level of cost implementation for effective life cycle costing on urban roads in the state. 09 30 2022 54 61 CC BY-NC-ND 4.0 10.35940/BEIESP.CrossMarkPolicy www.ijrte.org true 10.35940/ijrte.C7243.0911322 https://www.ijrte.org/portfolio-item/c72430911322/ Assistant Professor, Deogiri Institute of Engineering and Management Studies, Aurangabad (Maharashtra), India.

High strength concrete is being required due to the construction industry's growth. Admixture and supplemental cementing materials (SCMs) are employed to attain this strength. According to earlier research, nanoparticles with a high surface area to volume ratio, such as colloidal nano-silica (CS), which contains an amorphous silicon dioxide (SiO2) core and a hydroxylated surface, have the potential for extremely high chemical reactivity. This study examined the results of adding metakaolin and colloidal silica to concrete in varying amounts. Tests in accordance with Indian standards have been conducted in order to evaluate and compare the mechanical properties of concrete, such as compressive strength, split tensile strength, and flexural strength, while employing different percentage replacements of metakaolin and colloidal silica. According to Indian norms, 150mm cubes were cast for compressive strength tests and 150mm diameter by 300mm height cylinders were produced for split tensile strength tests. In the investigation, metakaolin was used in instead of 10 to 30 percent cement mass, and 0 to 6 percent colloidal silica was added. The results of the experiments indicate that the most optimal mixture, for which the most desirable strength was obtained, is 10% metakaolin and 2% colloidal silica. 09 30 2022 62 65 10.35940/ijrte.C7262.0911322 https://www.ijrte.org/portfolio-item/c72620911322/ Associate Professor, Department of Chemistry, K V Pendharkar College (Autonomous), Mumbai (Maharashtra), India.

Carbon nano materials (CNM) in the form of Graphene oxide and Reduced Graphene oxide decorated with metal nano particles were prepared from cotton as precursor – a green sustainable method. Various parameters were used for synthesis of carbon materials. Taguchi Optimization methodology – a statistical method, was used to arrive at the optimized parameters for synthesis to reduce the number of experimentations thus accentuating the green technology. Microwave is used in various techniques like communication, cell phones & satellite, military weapons viz. stealth technology, RADAR etc. The synthesized CNMs were assessed for their Microwave Absorption (MA) properties for their possible use as RADAR absorbing materials. 96 to 99% MA was observed in 2-8 GHz frequency range with reflection loss up to -25dB. These studies were carried out in the materials having thickness of 2-5 mm. Deviation in MA as well as in reflection losses were also observed when the decorating metal was changed due to the difference in the size of the metal atoms and corresponding shielding effects. 09 30 2022 66 77 CC BY-NC-ND 4.0 10.35940/BEIESP.CrossMarkPolicy www.ijrte.org true 10.35940/ijrte.C7263.0911322 https://www.ijrte.org/portfolio-item/c72630911322/
