KAJIAN KARAKTERISTIK FISIK PUPUK ORGANIK GRANUL DENGAN DUA JENIS BAHAN PEREKAT
ABSTRACT: Granular organic
fertilizer is a fertilizer that is partially or completely derived from organic
materials 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 research was conductedat 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 arrangement and three replications. The first factor consisted of two levels :
clay and starch. The second factor were
the percentage of the adhesives materials : 5%, 8%, 11%. Each experimental unit
weighted 4 kg raw materials of the organic fertilizer.The results showed that
11% of clay is the most optimal adhesive for making granular organic
fertilizers. Higher percentage of adhesives materials tended to increase bulk
density, durability, water absorption, and dispersion time of the granular
organic fertilizer. However, statistically the type of adhesives materials and
their composition had significant effect only on percentage of granule size for
2-5 mm and dispersion time.
