Evaluation on the Use of Plants and Equipment in Building Project Delivery in Imo State, Nigeria

Modern construction is characterized with complex designs, new and innovative materials that are sensitive with high precision. In addressing the accompanying challenges, mechanization of construction process is said to be the guarantee especially in this era of crash programmes and advancement in technology to reduce poor workmanship and eliminate avoidable holdup in construction processes in the industry. Amidst this belief, attributes of construction industry in Imo state still reflect ineffectiveness in the use of plant and equipment. Hence, the study assesses the involvement of plants and equipment in building delivery for improved project performance. Field survey and work measurement methods were adopted to gather both non-parametric and parametric data respectively. The survey design targeted the sampled building professionals while work measurement focused on selected earth and concrete works in the area of the study. Inferential and descriptive statistical tools of Chi-square on likert scale and Comparative measurements on work activities respectively were used to analyze the respective non-parametric and parametric data. Findings show that selection of various plants are dependent on their rates of use for increased site work productivity; while the socio-economic and political issues as militating factors against effective use of plants are determined by their levels of acceptance. It was also discovered comparatively that mechanization of construction processes is more time and cost effective in building project than manual approach at work. The study therefore recommends that a systematic and holistic awareness be created by the stakeholders on the usefulness of mechanization of construction process in physical development. Besides, government should enforce construction methodology plan as a mandatory document for approval of any building plans; while frantic effort should be targeted at reviving the abandoned steel manufacturing industry at Ajeokuta, Ogun state to revolutionize the construction methodology of construction industry in Nigeria.

Sistem Informasi Manajemen Penentuan Standar Waktu Kerja Metode Time Study Berbasis Web (Studi Kasus PT Eka Sandang Duta Prima)

Determination of the number of workers, costs, and working time into a standard measure of the working time of a product. Time efficiency and production reports become complex issues of the importance of production timeliness. The purpose of this study is to provide a design of an information system for determining working time standards that can be accessed integrated into a more efficient report form. Methods used with research and development where data collected from observations, interviews from case studies in the field. Determination of uptime standards using time study methods developed into web-based information systems using PHP programming languages with MySQL databases. The results of the design of this study, first contribute to obtain information that can help the management in determining management policy decisions. Second, fast and accurate determination of working time standards can provide customers with answers about price and fast uptime. Third, calculating the standard time of completion of work helps to choose the best alternative working method with the principles and techniques of work measurement at PT Eka Sandang Duta Prima.

A Service Management Metric with Origin in Plant Management

The discipline of industrial engineering (IE) was originated in the US by Frederick W. Taylor, who first applied what he termed scientific management to machine shop management in the 1880s. IE expanded world-wide with applications of work measurement to all manner of manufacturing, then to services. A century later, as the Japanese practice of Total Productive Maintenance (TPM) became known in the US, the associated equipment management metric Overall Equipment Effectiveness (OEE) became well-known as a production metric that could be applied to individual manufacturing machines, production lines, and the overall production system. In this chapter, illustrations of the calculation of OEE are provided, along with modification of the three OEE inputs (availability, performance efficiency, and quality rate) to create a new service management metric Overall Service Effectiveness (OSE). Definitions and measures of service quality are reviewed. The first published application of OSE was to a city public transportation system, and is reviewed as a prototype. Essentially, applications of OSE require the industrial engineer to define service-specific measures of availability, processing rate, and quality at the management’s level of interest: work station, process, or system. The data collected to calculate OSE will also point toward actions that would improve OSE.

Modernizing Archimedes’ Construction of π

In his famous work, “Measurement of a Circle,” Archimedes described a procedure for measuring both the circumference of a circle and the area it bounds. Implicit in his work is the idea that his procedure defines these quantities. Modern approaches for defining π eschew his method and instead use arguments that are easier to justify, but they involve ideas that are not elementary. This paper makes Archimedes’ measurement procedure rigorous from a modern perspective. In so doing, it brings a rigorous and geometric treatment of the differential properties of the trigonometric functions into the purview of an introductory calculus course.

A validation study of the Korean version of the thriving at work measurement

Purpose The purpose of this study is to validate the Korean version of the thriving at work measurement by Porath et al. (2012). Design/methodology/approach After translating the thriving at work measurement into Korean, the researchers assessed the validity and reliability of the measurement in a Korean working context using two different samples. In Study 1, the study validated the translated measurement using Rasch’s (1960) model, exploratory factor analysis and a reliability test with a sample of 322 employees. In Study 2, the study conducted a confirmatory factor analysis, a reliability test and a convergent and discriminant validity test using a sample of 187 employees. Findings Based on the analyses, this paper concluded that thriving at work has a two-factor construct and eight-item thriving at work measurement was better than the original 10-item measurement. The eight-item measurement demonstrated good discriminant and convergent validity. Originality/value This study validated the thriving at work measurement in a Korean context using Rasch’s (1960) model from the item response theory perspective.

ANALISIS BEBAN KERJA UNTUK MENGETAHUI JUMLAH PEKERJA OPTIMAL KARYAWAN POLISHING 3 DENGAN MENGGUNAKAN METODE WORKLOAD ANALYSIS DI PT SURYA TOTO INDONESIA, TBK

ABSTRACTHuman resources are one of the most important components in a company. In the production process at the polishing section 3 PT. Surya Toto Indonesia still uses human labor and an ineffective workforce. So it is necessary to carry out research actions to determine the optimal number of workers. PT Surya Toto Indonesia is a company engaged in manufacturing which produces fittings, sanitary and kitchen set products. The objectives of this study include knowing the productive presentation of workers in a direct observation activity, to determine the standard time according to the observation time obtained, and to determine the optimal number of employees at Polishing 3.In this study, the optimal number of workers was calculated using Workload Analysis method where work measurement is carried out first to 10 workers using Work Sampling so that the standard time value will be obtained. The results of this study indicate that the yield of productive presentation is 71%. While the standard time obtained in this study was 13.53 minutes. The optimal number of employees is 8.85 people, which in this case can be equivalent to 9 people. So the workload analysis results show that the number of Polishing 3 employees is still not optimal.Keywords: Work Sampling, Workload Analysis, Optimal Number of Workers
