Abstract

The industrial revolution and mass production directly increased human productivity and significantly impacted the environment. Amid these environmental problems, companies created environmentally friendly production strategies and prioritized economic factors (profit) and how they impact the social environment. This makes sustainable supply chain management in Sustainable Supplier Selection (SSS) increasingly in demand because it can affect the company's environmental performance. Companies that can improve their environmental and social performance will be able to increase their competitive advantage and impact, increasing revenue, market share, and a more positive green image of the company. There is no research on sustainable supplier selection in the sarong industry, especially in Indonesia. Therefore, research is needed on the sector because it dramatically affects environmental performance. One of the companies engaged in the sarong industry is XYZ company. This study aims to evaluate Supplier performance based on sustainable aspects (economic, environmental, social) using the cut-off point method for selecting sub-criteria, FAHP for assigning sub-criteria weights, and TOPSIS for ranking Suppliers based on predetermined sub-criteria. As a result of data processing, suppliers are ranked based on their preferences. As a result, Supplier 2 (S2) ranked first with a preference value of 0.9210, followed by Supplier 1 (S1) with a preference value of 0.7514, Supplier 3 (S3) with a preference value of 0.3166, and Supplier 4 (S4) with a preference value of 0.00019.

Abstract

In the current era of globalization, rapid advancements are driving nations to compete in strengthening their economies. Companies and industrial enterprises play a vital role as economic units actively contributing to national economic activities. Economic growth is closely associated with the output value of industries, which is significantly influenced by the number of workers. This study aims to examine the effect of the number of workers in micro-industries on the output value of micro-industries in Indonesia. The research employs two variables: the independent variable (X), representing the number of micro-industry workers, and the dependent variable (Y), representing the output value of micro-industries. A simple linear regression analysis was applied to measure the extent of the relationship between these variables. The results show a regression equation of Y = 217.512,365 + 46,669X with a coefficient of determination (R²) of 0,896, indicating that 89,6% of the variation in output value can be explained by the number of micro-industry workers. This suggests a strong influence of labor quantity on micro-industry output in Indonesia.
