“…The results of the characterization, normalization, and weighting of environmental impact can be seen in Table 3. The results of the LCIA show that the environmental impact is significant in the climate change category, acidification, human toxicity, and ecotoxicity (freshwater); this result is in line with research results [26,27,28] , which also have been researched environment impact from the metal industry.…”

Sampurna Kuningan is a small and medium enterprises (SMEs) specializing in creating various brass metal handicraft products. They need to improve their efficiency in producing brass door handles within their manufacturing process. The issues mainly revolve around two tasks - dipping and refining processes. At the finishing stage, the chemical solution left from brass cleaning is improperly treated and disposed of in the sewer, wasting resources. This study’s primary objective is to evaluate the eco-efficiency index (EEI) value and propose improvement strategies to reduce the environmental impact caused by their production activities. The eco-efficiency measurement involves comparing the financial performance represented by the net value and the environmental performance measured as eco-cost. The eco-cost is calculated using a life cycle assessment through the Sima-Pro software. The results of the calculations indicate an EEI value of 2.22. The production process is both economically affordable and sustainable. However, there is a relatively high environmental impact during the finishing process. Improvement scenarios for this process include implementing water treatment or substituting finishing chemicals. Using citric acid for a brass door handle yields a significant average reduction in eco-cost, reaching approximately 50%.

The batik industry is constantly increasing its production. During production, a curing machine is used to dry the batik after the printing/screening process. The main problem with conventional machines is their inability to produce maximum heat. Currently, they are used in most industries and generate uneven heat, with LPG gas as the main fuel. Therefore, this study aims to develop an electric curing machine as an alternative to overcome the challenges of the conventional type It was carried out using a sample of the experimental test site selected through a purposive sampling method, namely the Aluna Batik industry in Masaran, Sragen. The data were collected by observing the outcomes of mechanical engineering and analyzed using descriptive methods. The results showed that conventional curing provides an advantage in the speed of heat supply, while electric curing stabilizes heat requirements. This showed that the electric machine is more profitable for large and fast quantities production, while the conventional is ideal for daily production.

“…Every indicator has a unique weight and a unique size scale. As a result, normalization-a method of equating parameters-is required [25] [26]. Each indicator weight used in this measurement is transformed into a range of values, from 0 to 100.…”

A manufacturing company in Indonesia creates sports shoes under the particular brand is still having trouble with a number of issues, including late raw material deliveries from suppliers, production that falls short of expectations, and delayed product delivery to customers. The performance of the supply chain must therefore be measured. The study assesses the importance of supply chain performance within the organization and offer recommendations for improvement to raise supply chain performance within the organization. Analytical Hierarchy Process (AHP) and Supply Chain Operation Reference (SCOR) 12.0 are used to gauge supply chain performance. The outcomes revealed that supply chain performance’s value at 77,539. Improvements are required to increase the company's supply chain performance because three KPIs have low weights, the percentage of orders for raw materials that are delivered on time, the price of purchasing raw materials, and the cost of returning item. Corrective actions carried out by the company include arranging materials neatly in the warehouse, providing sufficient lighting, maintaining air humidity, keeping hands clean when holding shoes, checking glue on the upper shoes so that open bonding does not occur, giving penalties to suppliers who are late, and giving training to reduce material damage.
