Abstract

Organic fertilizer is fertilizer made from organic materials such as leaves, twigs, and livestock manure so
better keep the soil fertile than inorganic fertilizers . One form of organic fertilizer is granule shaped
fertilizers. Among the materials that can be made into organic fertilizer epidermal skin of soy generated by
home industries producing soybean cakes. The protein content of soybean epidermal skin is good for plant
growth. The purpose of this research is to utilize soybean skin into fertilizer granules.
This study followed a pre-experimental Post Test Only Design involving measurement after treatments.
Data collection was performed by measurements and laboratory testing . Data were analyzed descriptively
in reference to the Minister of Agriculture decree No.28 I Permentan I SR.130 /2009.
Results of the study especially on the examination of the C / N ratio was 14.40 and water content of
granular fertilizer was 24.80 % . It was pointed out that these results were not in accordance with the the
Minister of Agriculture Regulation No.28 / Permentan/ SR.130/ 2009 on Minimum Technical Requirements
Organic Fertilizer. Reduction of the C / N ratio was caused by the composting process that run longer.
That's becausethe decomposition processeswere uneven that impacted on the finished compost . Fertilizer
can still be used as a soil conditioner as the C I N ratio was in accordance with the regulations on the
Minimum Technical Organic Soil conditioners but it requires additional drying so that the water content of
the fertilizer falls within the standard that is 4-15 % .
It is recommended especially for the owner of a home industries to process soybean husks into fertilizer for
additional earnings and incomes. Farmers should start getting used to using organic fertilizers in
agriculture. Future researchers should perform aeration during the composting process so that compost can
mature completely perfectly and evenly . Educational institutions may use results of this study as an
innovative practice, especially in the areas of soil health and waste management
