Abstract

The aim of this study was to determine the economic and environmental feasibility of water hyacinth (Eichhornia crassipes) briquette. The economic feasibility was determined by the BCR, NPV, Payback Period, and BEP value. While the environmental feasibility was determined by the potential of water hyacinth briquette to control water hyacinth in Cirata Reservoir. Briquette A1P3 (the charcoal combinations of rice husk: water hyacinth 1:1 and the percentage of tapioca binder 5%.) was used in this research. The need of water hyacinth briquettes by a satay (tiny grilled chicken) seller and a grilled fish seller is greater than the need of charcoal and coconut shell charcoal. It shows that water hyacinth briquettes have a lower economic value than charcoal and coconut shell charcoal. A project of water hyacinth briquette processing is economically feasible with the assumption that all products sold because of the BCR value (1.1) > 1, and the NPV value (58,390,711) > 0, with Payback Period in 4.6 years and BEP 95,621.5 kg in 5 years. The use of water hyacinth briquettes by a satay and grilled fish trader at 20,949 kg briquettes/year has the potential to control water hyacinth in Cirata Reservoir of 0.02% per year.

Highlights

The existence of water hyacinth (Eichhornia crassipes) that covers the water surface of Cirata Reservoir leads to sustainable damages in all its dimensions [1]
Economic feasibility value was measured based on Benefit-Cost Ratio (BCR), Net Present Value (NPV), Payback Period, and Break-Even Point (BEP) [6, 7]
If it is assumed that the product of briquettes per year will be used by a satay trader and grilled fish (20,949 kg/year), the selling price of water hyacinth briquette is Rp 6,400 /kg (Table 1)

Summary

Introduction

The existence of water hyacinth (Eichhornia crassipes) that covers the water surface of Cirata Reservoir leads to sustainable damages in all its dimensions (social, economic, and environmental) [1]. To overcome these problems, the types of approach used must be based on sustainability theory [2]. The quality of the briquettes does not meet the SNI 01-6235-2000 standard on wood charcoal briquettes, but the burning performance was better than other briquettes because it produces less smoke, odours, and dust It is important since a thin and odourless smoke caused by water hyacinth briquettes do not interfere with the people breathing process. These briquettes do not produce dust so it is safe to be used in food processing [4]
