Abstract

Concrete has a major weakness in the form of low tensile strength, making it prone to cracking when subjected to tensile loads. Generally, this weakness is overcome by adding steel reinforcement or fibers. In the city of Pagar Alam, water hyacinth (Eichhornia crassipes) grows abundantly in the waterways and causes environmental pollution. This study aims to optimize water hyacinth waste as an additional material for concrete to enhance its tensile strength. Fiber-reinforced concrete was produced with varying additions of water hyacinth fibers at 0%, 2%, 2.5%, and 3% of the cement weight, with fiber lengths of 6 cm. The tests conducted included slump tests, specific gravity, compressive strength, and flexural strength. The results showed that normal concrete (BN) had the highest compressive strength, at 19.11 MPa at 28 days. Meanwhile, concrete with 3% fiber (BS3) yielded the highest flexural strength, at 4.76 MPa at 28 days. In conclusion, the addition of water hyacinth fibers can enhance flexural strength, although it does not significantly affect compressive strength. Thus, water hyacinth fibers have the potential to serve as an environmentally friendly alternative to reduce waste while improving concrete characteristics.

Abstract

Agricultural residues such as rice straw and coffee husks are often underutilized, despite their potential as cultivation media for straw mushroom (Volvariella volvacea). This study aimed to develop a rice straw–coffee husk-based cultivation model (Jadi-Jarang) within the Tunas Baru Farmer Group to promote business diversification, increase farmers’ income, and encourage environmentally friendly waste management. The cultivation process included media preparation, fermentation, spawn inoculation, mushroom house maintenance, harvesting, and post-harvest handling. Evaluations were carried out on mycelium growth, mushroom productivity, product quality, and socio-economic impacts. Results indicated that the combination of rice straw and coffee husks effectively supported mushroom growth, with evenly distributed mycelium, relatively short harvesting time (14–18 days), and fresh mushrooms of high market value. Moreover, this initiative enhanced farmers’ skills, reduced agricultural waste, and provided additional income. Therefore, the rice straw–coffee husk model offers both economic benefits and sustainable farming practices based on zero waste farming, making it a promising approach for farmer groups.
