Abstract

Granular organic fertilizer is a fertilizer that is partially or completely derived fromorganicmaterials in the form
of dense granules. The objectives of this research were to evaluate the effect of adhesives materials and their
compositions on the physical characteristics of granular organic fertilizer produced. This researchwas conducted
at the Bioprocess and Post Harvest Engineering Laboratory and also atPower and Agricultural Machinery
Laboratory, Department of Agricultural Engineering, Lampung University. The design of this study used
Randomized Complete Block (RCB)with factorial arrangementand three replications. The first factor consisted
of two levels : clay and starch. The second factorwere the percentage of the adhesivesmaterials : 5%, 8%, 11%.
Each experimental unitweighted 4 kg rawmaterials of the organic fertilizer.The results showed that11%of clay
is themost optimal adhesive formaking granular organic fertilizers. Higher percentage of adhesivesmaterials
tended to increase bulk density, durability,water absorption, and dispersiontime of the granular organic fertilizer.
However, statisticallythe type of adhesivesmaterials and their compositionhad significant effect onlyonpercentage
of granule size for 2-5 mm and dispersion time.
