Abstract

Quality tools are the ones that give cutting edge to the process or business. It carries remarkable weightage when it comes to the deliverables. A proper use of quality tool can provide break through improvements in quality, efficiency and the business results. The selection of such tools hence is very important. However, in spite of the importance the tools used may not be on the merit and may just get into place by a single person’s opinion or a trend or the thing in vogue or based on what the peers and competitors are using. Some times that tools are used only to show that it is part of their stable. This sorry state of selection is very common and companies end up paying hefty amounts for tool that are not good for them and are just a part of the introduction page of the organization. This paper is based on the study of the tools, their usage and their perceive benefits to assign a number to the tool that will tell the unitality or goodness of the tool for the purpose. There is not recommendation of a single tool for a purpose but it gives you a range of tools and range of alternatives that the user need to select from so that the purpose is met. The paper has two distinct parts, one sharing the name of the tools and their usage so that the user is aware what they are looking at and the other part is about the utility of these tools basically for improving quality of the product or process. Whever rating is done, the assessor needs to be well versed with the entity. Since there are quite a few tools considered here, it becomes very challenging to get right juries or assessors to rate the tools. However, thanks to the development of the Automobile Industry over past 140 odd years, which uses most of the tools under consideration, there are ample number of professionals who authoritatively can comment about the goodness of the tools. For this paper these were the group of elite professionals who were contacted. These are head of the department of quality, holding positions like President, Vice president, Directors, Senior General Mangers and so on. There were other senior professionals like Six Sigma Master Black Belt, Black Belts from reputed agencies like American Society of Quality (ASQ) and likes. most of these professionals were from Automobile OE manufacturers producing Cars, Trucks, Tractors & Farm Equipments, Two wheelers and Engine manufacturers. Based on their experience they rated these tools in 1 to 10 scale, 10 being the ones having most significant effect on quality improvement efforts and 1 being very low effect on quality improvement. The output of the research is in the form of a number assigned to the tool that tells about how effective this tool is in relation to the efforts to improve quality. Higher the number better the tool for the purpose.

Abstract

Green engineering emphasizes the efficient use of resources, sustainable infrastructure delivery, and integrated management systems to support long-term environmental and financial performance. In clean water infrastructure programs, particularly those implemented through philanthropic and waqf-based initiatives, managerial effectiveness plays a critical role in ensuring project sustainability. This study investigates how knowledge management, organizational communication, and accountability shape the financial performance of a clean water infrastructure program at Institution X. Using a quantitative explanatory design, survey data from 84 personnel involved in project implementation were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The results indicate that engineering management practices are implemented at a moderate level, while their impacts on financial performance are selective and mediated. Transparency shows a significant direct effect, whereas reporting and communication practices influence financial outcomes indirectly through knowledge sharing. Knowledge sharing emerges as the central mechanism linking governance and communication practices to efficient resource utilization and financial performance. The findings demonstrate that green infrastructure performance is not determined solely by technical design, but also by integrated engineering management practices that enhance coordination, knowledge utilization, and project sustainability.

Abstract

Productivity is defined as a comparison between the output (Output) and input (Input) in the company which can also be said as the ratio between the amount of output produced and the number of inputs used. The purpose of this research is to measure the productivity and environmental performance of the urea fertilizer production process at PT. X by using the Green Productivity approach. Green Productivity is a method that can be used to increase the level of productivity as well as environmental performance. The first step is to identify the source of the waste from the field study, determine goals and targets, and choose alternative solutions for Green Productivity. Based on the Green Productivity methodology, the alternative solution is selected by calculating the EPI (Environment Performance Indicator) index, and the Green Productivity Index (GPI) for each alternative. From the results of the selection of these alternatives, the best solution that can be proposed for improvement is alternative 1, namely repairing and maintaining the hydrolyzer engine and making hydroelectric turbines. This result is obtained from the calculation of the material, labor, energy, and maintenance indexes which are above 1 which indicates a problem solving by selecting and implementing this alternative as a solution. The material GPI is 1.31, the human GPI is 1.05, the energy GPI is 1.11, the maintenance GPI is 1.01 and the waste GPI is 0.58. Meanwhile, the EPI index of human health is 16.67 and the EPI index of flora and fauna health is 15.23.

Abstract

Currently, the demand for cleanrooms is quite high. With the growth of the food industry, medical equipment, and hospitals, the need for these spaces has become increasingly important. Cleanroom classifications are regulated in various literature, such as ISO, SNI, NFPA, and others. In ISO 14644-1, cleanroom classification is divided into several categories: Class 100,000 (ISO 8), Class 10,000 (ISO 7), Class 1,000 (ISO 6), and Class 100 (ISO 5). The differences between these classifications lie in temperature, humidity, air changes per hour, particle quality, and airflow distribution.To maintain humidity, electric heaters are generally used as equipment. The energy requirement is quite high, and in an AHU system, this device creates an additional heat load because it generates the full sensible load. In this study, the use of a heat compressor or heat recovery unit could be an option for maintaining humidity in a room conditioned by an HVAC system. The flow rate of the high-temperature, high-pressure refrigerant will be regulated using a solenoid valve triggered by a humidity sensor. A defrost mechanism will be implemented within the heat recovery coil to prevent freezing within the system. The results of this study state that the energy required for a cleanroom AHU system that uses heat recovery for air humidity conditioning is more efficient than using an electric heater.
