PEMANFAATAN LIMBAH PENYULINGAN BUNGA KENANGA SEBAGAI KOMPOS DAN PENGARUH PENAMBAHAN ZEOLIT TERHADAP KETERSEDIAAN NITROGEN TANAH
Abstract: The research about
exploiting of waste distillation of cananga flower as compost and influence
addition of zeolite to availibility of nitrogen in the soil has been
conducted.Making of compost was done with heaping method, there were three
variation of treatment to waste distillation of cananga flowers, they were (1)added
by EM 4, (2) added by EM 4 and sawdust (3)without any addition (as
control).Physical perception like temperature, odor and colour were conducted
at the time of composting process. .Chemical analysis of C/N ratio was done to
compost which have matured. After that, the compost added by zeolite on
variation of amounts that was 2%, 4% and 6% to compost weight, then they used
at maize crop.Result of research indicate that the compost was made from waste
distillation of cananga flower added by EM 4 reaching optimum temperature at
39oC. The compost ready to harvested after 21 day, this compost has C/N ratio
about 11,61. Meanwhile, at addition of EM 4 and sawdust could reached optimum
temperatur at 45oC and ready to harvest after 20 days. This compost has C/N
ratio about 43,81, while without any addition, optimum temperature was reached
at 37oC and ready to harvest after 43 days with C/N ratio about 16,18.The
results show that compost can be made from waste distillation of cananga
flowers with addition of EM 4. Usage the compost that was added zeolite at
maize crop can be increasing nitrogen rate at soil. Addition of zeolite 2%
nitrogen rate equal to 0.96%, zeolite 4% equal to 1.90% and zeolite 6% equal to
3.31%.
