Selection strategy implementation of cleaner production using ISM and AHP Method in Chemical Laboratory of Service Industries

Abstract The chemical analysis in the service industry cannot be separated from energy use, water, consumables, and chemicals related to the amount of waste produced. The number of hazardous solid waste generated in the CRS Chemical Laboratory division has increased in certain months, ranging from 400-600 kg. This shows the low implementation of green production in the company. Therefore, the purpose of this study is to analyze the key criteria and determine the best strategies to reduce waste. The method used in this study is Interpretive Structural Modeling to find key criteria and the Analytic Hierarchy Process method to determine the priority selection of clean production implementation strategies. This study uses a questionnaire distributed to four experts. The results showed that there were nineteen sub-criteria analyzed in determining key criteria. The sub-criteria for lack of awareness from both individuals and organizations regarding changes for the better is a key criterion in the application of cleaner production. Furthermore, the best alternative calculation results using the AHP method obtained by the implementation of periodic green production socialization to employees has the greatest valuation of 0.57 with a Consistency Ratio (CR) of 0.09. Further research is needed to evaluate the alternatives chosen.</jats:p

Strategy for minimizing risk of electronic waste management using the Analytical Hierarchy Process (AHP)

Abstract Electronic waste management is one problem that has the potential to pose a risk to the environment and human health. The strategy to minimize the impact level on e-waste management has been extensively carried out in almost all countries. This paper aims to analyse strategies for minimizing the risk of e-waste management. The AHP method was used in this study. The assessment used a paired comparison questionnaire by five experts such as academics, governments and NGO. Studies show the first priority strategy is improving regulation and monitoring with a weight around 0.493. In addition, the sub-criteria chosen by experts are legal compliance with a weight of approximately 0.629 and the criteria that are the top priority are regulations with a weight of around 0.525. The assessment by experts also shows the value of the consistency ratio of around 0.07. This research can be a strategy by policy makers to manage sustainable e-waste. It is considered necessary to conduct further research related to other criteria and sub-criteria that may be different in the management of e-waste in other regions.</jats:p

Frequency Invariant Beamformer Robust Against Array Element Mismatch

This paper extends the design of frequency invariant beamformer by incorporating robustness in the design formulation to cater for array element mismatches and other non-ideal characteristics. In this approach, a 2-norm constraint on the filter weight is imposed into the design optimization problem. The constraints limit the norm of the beamformer coefficients and thus reduce the sensitivity of the beamformer towards then on-ideal characteristics of the microphones. Design examples and comparisons are presented to illustrate the effectiveness of our approach

The problem on this research was found that there are several parameters on the wastewater not comply such as pH and TSS to Indonesian Standards. This study aims to analyze the value of process capability resulting from wastewater treatment, especially parameters of pH and TSS. Several methods used in this study such as IMR control chart, capability process, and fishbone. The results of this study show the parameters of pH and TSS from the wastewater treatment in the pharmaceutical industry obtained the average Cp index of around 0.602 and CPK approximately 0.8 for pH parameters. In addition, the quality of wastewater for TSS parameters obtained CP index roughly 0.68 and CPK approximately 0.70. Therefore, it can be concluded that the process does not have a good capability

Analysis of risk failure of solid waste management processes in universities: Case Study of Pancasila University Jakarta

Abstract The concern for environmental impacts is environmental degradation. One of the environmental problems is solid waste which has the potential to cause dangerous risks. Therefore, this study will analyze the risk of solid waste management factors at the university using the Failure Mode Effect Analysis (FMEA) method. Some information about risk factors from the solid waste management process was collected using literature studies and Ishikawa diagrams. The number of experts or experts used in this study was 5 people. The expected results of this study will be able to show the value of the Risk Priority Number (RPN) of the factors that are the target of the study. Furthermore, from this value, the level of risk can be known from each factor. Thus, risk evaluation (priority risk to be controlled) in the solid waste management process is focused on the highest risk category. The results of this study can be a guideline for evaluating solid waste management in universities in Indonesia and other developing countries. Various developments to improve the results of this study need to be carried out that will be useful for future actions.</jats:p
