Nowadays, maintenance performance in organizations has become compelling due to competitiveness in the global market and the inclusion of more legislation issues (such as safety and health regulations) in assessments. In this article, the purpose is to formulate in maintenance problem for a food processing unit as a multicriteria problem and solve it using the evaluation based on distance from the average solution (EDAS) method. To attain this purpose, the authors defined a set of weighted criteria and a set of alternatives, and the solution is the alternative that scores the best in those criteria. Consequently, analysis was done based on the EDAS method and the calculated results from the literature data. Consequently, the parameters considered include the frequency of failure, MTBF, MTTF and MTTR while availability is the response. The EDAS method was used to select the best alternative (MTTR, 0.8802) and this score of 0.8802 is for an alternative. The chief novelty of this article is the unique introduction of an innovative EDAS method, which requires only two measures of the desirability of alternative (positive and negative distances from the average solution) but excluded the evaluation of the idea and nadir solutions for the key performance indicators of maintenance. Consequently, this study initiates a maintenance plan for the food industry referring to the key performance indicators as a cause for poor availability of equipment in the Nigerian food industry.

Selecting cutting tools for a milling process is crucial to determine the optimal cut. Minimizing milling process-cost is one of the most common optimization objectives, and thus it determines the best cutting tool to be used. However, the chosen cutting tool might not bring the optimal result based on the tool’s cost. Therefore, a valuation method based on the process and cutting-tool costs results were developed and analyzed to improve the cutting tool selection process. A specific rough-milling operation was entered to the quick cost-estimation and optimization application, and several cutting-tools were compared based on the process-cost by each tool. Using a weight-based analysis on both process-cost and tool-cost changes the cutting-tool options' initial rankings. This study showed that using different weight ratios altered the order of the most suitable cutting tools. Another finding revealed in this study is how deflection constraint affected the rank of cutting tool selection. Thus, knowing the proper limit of deflection is crucial to validate the cutting tool selection outcome.

Based on data from SIPSN (Sistem Informasi Pengolahan Sampah Nasional) Ministry of Environment and Forestry, Indonesia's waste stockpile in 2020 reached 33 million tons, and 17.12% of it was plastic waste. The government has several alternative solutions in waste management, such as the creation of a waste bank, compost house, maximizing the 3R (reduce, reuse, and recycle) program, and applied plastic waste for renewable energy. Research on the use of PP plastic waste for the manufacture of recycled yarn cones is also included in the use of the 3R program which is being discussed by the government. The aim of this research is to obtain the mechanical characteristics (flexural strength) and mass weight between the cones made from recycled PP and pure PP. Based on the observations that have been made, the cone product with PP material has a compressive strength characteristic of 0.4 – 0.8 kg/mm2 and a weight of 10.5 – 11.5 grams. The study of the use of PP plastic waste to be used as a cone product begins with preliminary research related to optimizing product manufacturing parameters on injection machines. The next step process is making cone products with added calcium material. After the product has been printed, the next step is flexural testing and measurement of the mass of the product. Based on the test results, the product of pure PP cone material with 5% and 10% calcium carbonate added, and recycled PP material with 15% calcium carbonate addition is the result that meets the mass standard (10.5 g to 11.5 g) and flexural strength. (0.4 kg/mm2 to 0.8 kg/mm2). Because the focus of research is on the use of plastic waste, so the ideal cone product is recycled PP material with the addition of 15% calcium carbonate.
