PENGARUH RASIO FESES SAPI DENGAN TANDAN KOSONG KELAPA SAWIT TERHADAP KADAR FOSFOR DAN KADAR KALIUM KOMPOS

This study aims to determine the effect of the ratio of cow feces to TKKS on
phosphorus levels and potassium levels of compost. The research method used in
this study is an experimental method with a completely randomized design (CRD).
In this composting process, the treatments were P1 (60% cow feces + 40% TKKS)
P2 (50% cow feces + 50% TKKS) P3 (40% cow feces + 60% TKKS).The method
used for the measurement of compost content uses the spectrophotometric method
(Uv-Vis). Based on the results showed that from all ratios of cow feces to oil palm
empty fruit bunches had no significant effect on potassium content and phosphorus
content of compost. Potassium content produced = P1 0.28%, P2 0.27%, P3 0.31%.
This value has met the standard requirements of SNI 19-7030-2004 potassium
levels for compost which is 0.20%. Phosphorus content of the resulting compost =
P1 0.23%, P2 0.22%, P3 0.23%. This value has met the standard requirements of
SNI 19-7030-2004 for compost phosphorus, which is >0.10%. The nature of the
compost produced in this study has also met the compost standard. The results of
this study can be applied to soil or plants.
