Study and measurement of the productivity in the printing industry in Villahermosa Tabasco to develop an improvement proposal

Productivity is one of the paths that a company must take to achieve its objectives, goals and purposes, working effectively and efficiently. To achieve a culture of measurement, it is important to perform a productivity analysis, which will help to obtain adequate information to create development recommendations in the near future. This work provides information on the results obtained from a productivity measurement study in a sample of companies in the printing industry, in Villahermosa Tabasco, which helps to understand and adapt business needs within the cultural, environmental, technological, economic and political variables. To carry out this study, a measurement instrument has been used that obtains specific information on the elements that an organization must have for the development of productivity, this tool is called Comprehensive Productivity Assessment Technique (TIEP), the which will give us results that serve to generate a model for improving productivity, which will be of great help for the growth of this business sector with positive results that bring benefits to the region and society.

Productivity Analysis Using Method Murvin E. Mundel Case Study PT. Johan Sentosa

Productivity is an alternative to evaluating the performance that has been done even one of the most effective ways in assessing the efficiency of using several inputs in producing certain outputs. the study was conducted at PT Johan Sentosa. The company is engaged in processing palm oil into CPO (crude palm oil) and kernels. In this case, the company must replace an important process called the sterilizer system from the horizontal sterilizer to the vertical sterilizer. This change will certainly have an impact on company productivity. In this study, the method used is Marvin E Mundel where partial productivity will be identified in the form of depreciation value index, material, labor, energy, and maintenance, and know the total production value index. The results of this study obtained a partial productivity index on the declining workforce, other partial productivity such as depreciation, material, labor, energy, and maintenance have increased while the index value of total productivity increased after a change in the sterilizer system.

On the One-Point Model for the Productivity Evaluation in Jingbian Sector of Yan’an Gas Field

The productivity equation of a gas well is, in the final analysis, an expression that describes the relationship between the production of a gas well and its bottom-hole flowing pressure. There are two kinds of productivity equations in common use at present: binomial productivity equation and exponential productivity equation. Combined with the modified isochronal well test, the test data are interpreted, and it is found that the open flow rates calculated by the two productivity equations are basically the same when the pressure difference at the test point is large, and the deviation of the exponential productivity equation is large when the pressure difference at the test point is small. Using binomial productivity equation and modifying isochronous well test, we established the single-point deliverability formula for the Jingbian sector of the Yan’an gas field. The field experience formula and production data are used to verify it. Their average errors are 2.59% and 7.12%, respectively; and the coincidence rate of productivity evaluation is 90%. The one-point productivity formula established has high precision and is suitable for productivity analysis of gas wells in paleozoic reservoirs in the Jingbian sector of the Yan’an gas field. This paper provides insights into the one-point productivity evaluation and its future application in the gas field.

Productivity Analysis of Crude Palm Oil (CPO) in PT. Ramajaya Pramukti Using Value Stream Mapping Approach

This study aims to analyze the productivity of CPO processing using Value Stream Mapping (VSM) approach. A case study conducted in PT. Ramajaya Pramukti, Indonesia. The research method used the VSM and Process Activity Mapping (PAM) to determine wastes in the process flow of CPO production. The data was collected in 1 month. The preliminary result of CPO productivity process was average of 73.67%. Based the Future Value Stream Mapping (FVSM) the CPO processing time can be efficient from 1.981 seconds/kg to 1.963 seconds/kg. The productivity processing for value added 1.525 seconds/kg, which non value added of 0.012 and the non necessary value added of 0.383 seconds/kg. The quality of raw materials was the biggest waste contributor. It was caused a longer processing time due to poor quality of raw materials.

Research Productivity in Emerging Economies: Empirical Evidence from Kazakhstan

The growth of the Higher Education and Science (HES) sector is positively associated with its research productivity and has a high potential in emerging countries. To explore such research productivity, this study offers a comprehensive analysis of the scientific literature from Kazakhstan. Our methods included descriptive analysis, network analysis, and author-based productivity analysis (by Lotka’s law) of 23,371 articles from Scopus, published during 1991–2020, and across 25 subject areas. The results of the descriptive analysis showed a substantial increase in the number of and citations to the literature since 2011 in almost all subject areas. However, the network analysis found that research in natural sciences was more developed in topical relationships and international collaborations than research in arts and humanities, social, and medical sciences. The Lotka’s law application revealed that the overall scientific literature in Kazakhstan did not reach its necessary stage of maturity. Additionally, some subject areas demonstrated greater contribution to the overall knowledge base, while others were less productive or lagging in their development. Our findings, useful for researchers and policymakers in emerging countries, can be exemplary in understanding the results of policy reforms aimed to improve the HES sector in emerging countries.

Green productivity analysis of raw rubber production

Rubber is a well-known commodity that has been cultivated for a relatively long time in Indonesia. Rubber plays an essential role in contributing foreign exchange incomes, job opportunities, and providing industrial raw materials. In 2014, Indonesia became the second-largest rubber producer after Thailand, with a rubber yield of 3,979 tons. Increased rubber production is linear to the environmental damage that occurs so that productivity improvement tools based on environmental or green productivity are needed. This research aims to determine the factors influencing productivity level and improvement efforts by considering the environmental performance indicator. The method used is the Environmental Performance Indicator (EPI). Two expert respondents filled the weighted result, i.e., academician and head of waste treatment. The selection of alternative improvement using Benefit-Cost Ratio (BCR). The result is Multi Soil Layering (MSL) which could save the cost of IDR 253,651,626.2 per year or 70% water savings. This alternative can increase productivity by 11.12% from 76.13% to 85.25% and raise the EPI value of 0.766 from 0.201 to 0.967.
