Abstract

The Kampung Emas Tourism Area, renowned for its traditional eateries offering authentic Javanese cuisine, has become a favored destination for tourists. However, the surge in tourist numbers has contributed to increased organic waste. Addressing this issue is crucial to prevent environmental problems and negative perceptions of Kampung Emas. The community service initiative aims to introduce rapid composting technology as an innovative solution to enhance understanding and effectiveness in waste management within Kampung Emas. The activity was conducted on August 12, 2023, involving 15 managers from the tourism sector. Emphasizing organic waste management, the initiative introduced the innovative solution of rapid composting technology. Evaluation was carried out through questionnaires distributed before and after the activity. Participants grasped organic waste management concepts yet demonstrated a greater understanding of composting technology. The evaluation results showed a significant improvement post-activity, with an understanding rate of 83% for waste management concepts and 60% for composting technology. In conclusion, the initiative successfully increased knowledge and understanding among Kampung Emas management regarding rapid composting technology, providing a solid foundation for implementing more effective and sustainable culinary waste management practices.

Abstract

The selection of green-based suppliers remains a challenge for manufacturing firms in Indonesia. In today's business landscape, it is crucial to consider green aspects as part of sustainability practices when choosing suppliers. However, there is a limited number of studies providing frameworks for selecting suppliers based on green factors, particularly in developing countries. This study aimed to propose a framework for selecting suppliers using multicriteria decision-making (MCDM) techniques. A case study was conducted in an Indonesian metal manufacturing company that considers carbon reduction and incorporates traditional supplier selection factors such as quality, cost, and capacity. The study integrated two MCDM techniques, namely the best-worst method (BWM) and Višekriterijumsko Kompromisno Rangiranje (VIKOR), to evaluate and select green-based suppliers. BWM was employed to determine the weights of the criteria, while VIKOR ranked the suppliers. Seven criteria were identified, including cost (C1), quality (C2), delivery time (C3), technology application (C4), compliance with environmental regulations (C5), green practice certification (C6), and green efforts (C7). Nine suppliers were screened and ranked accordingly. The results indicate that quality, delivery time, and cost are the top three ranked criteria based on their importance. Further, this study includes nine suppliers in which supplier S7 demonstrates the best performance compared to the others. This study highlights that in Indonesia, most organizations tend to prioritize traditional criteria, while green factors are still overlooked. However, the company examined in this study has taken the initiative to include environmental factors in its decision-making process. The findings of this study contribute to the development of a framework for selecting green suppliers in a developing country context.
