Abstract

Pinogu coffee is a superior coffee from the Gorontalo region. Pinogu coffee is a type of robusta coffee. From the results of the research conducted, this Pinogu coffee has sensory characteristics that tend to be bitter (taste and aftertaste) with the aroma of smoke and wood, followed by a burnt and roasted aroma and a slightly thick body or texture that coats the oral cavity. As for the chemical characteristics, ground Pinogu coffee contains a water content of 2.51%, caffeine content of 1.99%, and copper content of 13.86 mg/kg, for steeping the coffee contains a caffeine content of 0.06% and copper content of 0,39 mg/kg.

Abstract

This study developed a sheet-type organic mulch from coconut fiber, banana pseudostem, and water hyacinth without synthetic additives through drying, alkaline pretreatment in 1% NaOH solution for 30 minutes, pulping, molding, and oven-drying at 50 °C for 72 hours. The products were characterized for physical, mechanical, and chemical properties, including moisture and ash contents, water absorption capacity, tensile strength, and proximate, lignocellulosic, CNPK, FTIR, and SEM-EDX analyses. The raw materials showed distinct compositions: coconut fiber was rich in lignin (27.52%) and cellulose (37.87%), banana pseudostem had the highest hemicellulose (36.25%), and water hyacinth contained the greatest protein content (16.74%). Among treatments, M3P3 (70% coconut fiber: 30% banana pseudostem) exhibited the highest water absorption capacity (257.00%), while P1 (100% banana pseudostem) achieved the highest tensile strength (9.97 N). In contrast, E1 (100% water hyacinth) showed the highest moisture content (8.83%) but the lowest tensile strength (5.11 N). FTIR and SEM-EDX results confirmed the presence of hydroxyl and carbonyl functional groups and a porous surface morphology, supporting water retention and nutrient release. Overall, the composite mulch demonstrated eco-friendly, economical, and adaptive properties suitable for sustainable tropical agriculture applications.
