Abstract

Efficient use of irrigation water is essential because water availability often does not meet crop requirements. In response, compost application is a potential solution, as it improves soil structure and enhances water-retention capacity. Nevertheless, the water-binding capacity of compost varies depending on the source of animal manure. To address this, the study aimed to evaluate the effectiveness of compost made from cattle, poultry, and goat manure in improving water retention in Andosol soil and supporting tomato growth as a biological indicator. The study used Andosol soil mixed with compost at application rates of 25% (500 g), 50% (1000 g), and 75% (1500 g), along with a control without compost. A two-factor completely randomized design with three replications was applied, and measured parameters included moisture content, media weight, water-holding capacity, pH, plant height, and leaf number. Results showed that the treatment using 1500 g of goat manure compost combined with 500 g of Andosol soil produced the highest water-holding capacity, making it the most effective option for irrigation water conservation. In contrast, cattle manure compost yielded the best tomato growth and productivity. Overall, these findings demonstrate that selecting the appropriate manure-based compost can enhance soil water retention and improve irrigation efficiency.

Abstract

Arabica coffee husk is a by-product of coffee agroindustry that is generated in large quantities and has not been optimally utilized, particularly in coffee-producing areas such as Bondowoso Regency, Indonesia. Proper postharvest handling is required to reduce its moisture content in order to extend shelf life and enable further processing. This study aimed to investigate the drying characteristics of Arabica coffee husk using a hot air oven at different temperatures (40, 60, and 80°C) and to determine the most suitable mathematical drying model. Fresh coffee husk samples weighing 100 g were used for each drying treatment. The observed parameters included moisture content reduction, drying rate, and moisture ratio. Experimental drying data were fitted using Newton, Page, Henderson and Pabis, Logarithmic, and Midili models. The results showed that increasing drying temperature significantly accelerated moisture removal and increased the drying rate. Drying occurred predominantly in the falling rate period, indicating that internal moisture diffusion controlled the process. Among the evaluated models, the Logarithmic model consistently provided the highest coefficient of determination and the lowest fitting errors at all drying temperatures. These findings demonstrate that the Logarithmic model is the most appropriate for predicting the drying behavior of Arabica coffee husk dried using a convection oven. The results of this study are expected to support process design and decision-making in the management of coffee agroindustry, particularly for the utilization of coffee husk in Bondowoso.
