Abstract: This study was aimed to assess the changes in soil physical properties and plant growth of coffee due to the application of Tithonia compost and Coffee bean skin compost. The research was conducted in the Paya Tumpi village, Kebayakan of Aceh Tengah District at the altitude of ± 1300 m above mean sea level. The factorial randomized block design was used in the experiment, consisted of two factors i.e: (1) Tithonia compost and (2) Coffee bean skin compost, and replicated three times.The results of this study showed that the application of Tithonia compost and Coffee bean skin composthad significant interaction effect on aggregate stability index and plant height. The single application of Tithonia compost had significant effect on soil bulk density, permeability, porosity, aggregate stability index, slow drainageporosity, rapid drainageporosity, water availableporosity,and plant height at the age of 11 and 14 months. The single application of Coffee bean skin compost had significant effect on soil bulk density, permeability, porosity, aggregate stability index, slow drainageporosity,water availableporosity, plant height and leaves area at the age 11 and 14 months. The optimum dosage of Tithonia compost and coffee bean skin compost was 3.75 kg plant-1. Keywords: Tithonia compost, Coffee bean skin compost, soil physical properties, Arabica coffee.
