Sustainable manufacturing performance evaluation tool for automotive companies

In response to the growing sustainability concerns, manufacturing companies have to formulate a set of measures to evaluate sustainable manufacturing performance, aimed at integration of sustainability aspects. Sustainability is generally evaluated by dimensions of environment, economic, and social, known as the triple bottom line (TBL) of sustainability. However, while the literature on sustainability is rapidly growing, only few studies have attempted to integrate sustainability into manufacturing performance evaluation. There is also no consensus yet on a standard set of sustainable manufacturing performance measures. This study aims to integrate sustainability into manufacturing performance by incorporating manufacturing performance measures with sustainable manufacturing measures. As a result, a set of initial measures for sustainable manufacturing performance evaluation believed to be suitable for automotive companies have been proposed, consisting of three factors divided into nine dimensions and a total of 41 subdimensions. In order to validate the initial measures with industry practices, a survey was conducted on the automotive companies in Malaysia. It was found that all the initial measures are highly important and thus proposed as the key measures of sustainable manufacturing performance evaluation for automotive companies. A sustainable manufacturing performance evaluation tool for automotive companies was then developed using a hybrid Multi Criteria Decision Making (MCDM) technique. Interpretive Structural Modeling (ISM) methodology was applied to determine the structural relationships and inter-relationships amongst all the performance measures and Analytic Network Process (ANP) methodology was employed to determine the important weights of each of the performance measures by summarizing the opinions of the experts. While the tool provides a systematic approach for quantitative assessment of sustainable manufacturing performance, it is not entirely automated. Thus, for that purpose, a software-based tool named SUSMAP was subsequently developed using PHP and MySQL. Two case studies have been conducted to validate the tool. Results from the case studies suggested that the SUSMAP is easy to use and applicable to evaluate sustainable manufacturing performance in automotive companies. The tool can be used by companies for self-assessment as well as benchmarking. It shows the existing performance level on strengths and weaknesses, and where improvements need to be made. It is hoped that the proposed sustainable manufacturing performance measures and the associated SUSMAP tool can aid the automotive companies to achieve successful implementation of sustainable manufacturing so as to compete in a much more sustainable manne

Determination of Optimal Clinker Factor in Cement Production by Chemical Grinding Aids Addition

The cement industry has remarked as an intensive consumer of energy. The amount of energy consumed in the cement manufacturing has a correlation to the increasing of CO2 emission. It is reported that the cement Industry has contributed to 5–7% of the total CO2 emission in the world. Thus, there is a need to make an innovation in order to overcome the environmental problem. One of effort can be made is by using chemical grinding aids (CGA) as an additive material in the cement production process. This study aimed to determine the optimal clinker factor of the cement production by the addition of chemical grinding aids (CGA). The experiments are conducted in PT Semen Padang consisting of four variable of the clinker factor without CGA and with CGA addition 300 ppm. The clinker factor varies from 78.3% to 72.9%. The results show that the optimal clinker factor is at 74.5% with the CGA addition 300 ppm. It can improve the cement fineness to 3848cm2/gr and decrease the sieving R45μ to 10%. In addition, the strength of the cement produced is higher than the standard. The findings show the chemical grinding aids (CGA) addition in the cement production process can reduce the clinker factor as well as reducing the CO2 emissions. It can aid the cement industry to achieve the higher performance in green manufacturing and so as to increase the competitiveness

Key Performance Indicators for Sustainable Campus Assessment: A Case of Andalas University

Sustainable campus has became an important issue amongst universities around the world. Universities can generate a significant impacts to environment due to the high usage of energy, extensive transportation, massive waste, high consumption of materials, and extensive development of buildings and facilities. Thus, there is a need to assess the sustainable campus performance. This paper proposes a set of key performance indicators (KPIs) for sustainable campus assessment consisting of six categories divided into a total of 35 indicators. Analytical Hierarchy Process (AHP) method is applied to determine the importance weight of the KPIs. The results indicated the most important category for the sustainable campus assessment is education with an importance weight of 0.2665, while energy and climate change is regarded as the least important category. It is hoped the proposed KPIs can assist the universities to achieve the higher performance in sustainable campus

Sistem Pengukuran Kinerja Supply Chain Management Pada Proyek Konstruksi

Construction project implementation process is often found inefficiency and problems at every stage of the construction process. Inefficiencies are caused because construction projects have high levels of fragmentation. The high level of fragmentation cannot be separated from the complexity and many work items on construction projects. To reduce the problem of inefficiencies in the implementation of construction projects required good supply chain management or better known as supply chain management (SCM) on construction projects. Therefore it is necessary to study the management of SCM in the construction project to reduce the inefficiency that occurred. SCM management of construction projects is done by designing SCM performance measurement systems in construction projects. This performance measurement system produces indicators that are combined with the Supply Chain Operation Reference (SCOR) method. So it helps in performing SCM performance measurement on construction projects. From the design results, obtained 14 SCM performance indicators on construction projects. The performance indicators are then used to perform SCM performance measurement of cement plant construction projects. From the measurement results obtained SCM performance value of 41 from a scale of 100. This shows the performance of SCM on construction projects for the construction of the cement plant is at a marginal level
