| Summary: | Processing of soft drinks from tea leaves (Camellia Sinensis) produces
industrial waste in the form of tea waste, which PT. Sinar Sosro Ungaran production
reached 250 tons per year (PT.Sinar Sosro Ungaran, 2010). One of the efforts of
waste management and utilization of tea waste is to recycle (recycle) of tea waste by
composting The purpose of this study to determine the extent of the influence of
various biostarter and worms Eisenia foetida against the speed and quality of the
composting process solid waste of tea.
Compost material used was a mixture of tea waste at 20 kg and 2 kg of bran
that has been fermented. Compost materials were given 4 treatments with 3
repetitions. Biostarter used in this study were: biostarter stardec, Biostarter EM4, and
biostarter biostarter MOL which is local, that is made of the remaining vegetables
and fruit rot, and the worm Eisenia foetida as local Biostarter biodecomposer is an
alternative to reduce the use and application of manufactured biostarter very easy for
farmers. Biostarter was added to the raw material of organic waste to help the
composting process faster is more or less 21 days. Once every 7 days composting
analyzed C / N ratio, content of C, N, P, K, to determine the effect of adding various
biostarter and worms Eisenia foetida.
The results of C / N ratio with biostarter MOL, worms Eisenia foetida,
biostarter EM4, and biostarter Stardec are: 16.08, 16.73, 18.32, 18.86 of this value
according to SNI 19-7030-2004 which is 10 - 20 compost was mature. Value of N
content (%), P (%), K (%), with the corresponding value in comparison to the SNI
19-7030-2004 C, N, P, K, C / N ratio with SNI 19-7030-2004. Treatment with MOL
to provide the results of quality compost such as the content of N, P, K and C / N
ratio better than other treatments ie, 1.08% N, 1.71% P, 0.65% K and 16.08 C/N
ratio.
