Optimizing Rattan Waste Processing in Furniture Production with a Green Supply Chain Model Approach

Abstract

This research examines the application of a green supply chain to support the implementation of zero 
waste in the rattan handicraft industry. In general, the production process of rattan handicrafts uses raw materials with 
a length of 3 to 5 meters to produce products such as chairs, tables, and baskets. However, there is a significant problem 
in the form of residual rattan waste measuring 15 to 30 cm that is often discarded by craftsmen, thus triggering waste 
of raw materials. To overcome this, the concept of green supply chain is applied with the aim of optimally utilizing 
all available raw materials, including recycling the remaining materials into by-products of economic value, such as 
key chains, bracelets, and other accessories. A mathematical model is used to formulate an optimization strategy that 
considers the costs of raw materials, transportation, energy, and waste management. The objective function of the 
model is to minimize the total cost and maximize the value of the by-products, without applying a closed-loop 
approach. This research shows that implementing a green supply chain can significantly reduce waste, lower 
production costs, and improve resource efficiency, without compromising product aesthetics. In addition, the concept 
supports economic sustainability by utilizing waste as an additional resource, while reducing the environmental impact 
of the rattan handicraft industry. The implementation of a green supply chain is proven to improve the competitiveness 
and sustainability of this industry.
