APLIKASI AKTIVATOR UNTUK MEROMBAK ECENG GONDOK (EICHHORNIA CRASSIPES (MART.) SOLMS.) DARI DANAU TOBA MENJADI PUPUK ORGANIK
ABSTRACT: Organic fertilizers
such as compost is a natural fertilizer to add nutrients in the soil.Compost
can be regarded as the product of fermentation of organic materials with a
large number of microbes.The addition of activators or inoculum on the
composting is part of an effort to accelerate the composting process. This
research was done in November 2015 until January 2016 in experimental garden
land USU campus in Padang Bulan, Medan. The experiment used a factorial
randomized complete block design (RAK) factorial consisting of two factors.The
first factor is the type of organic material consists of two levels the water
hyacinth (Eichornia grassipes (Mart.) Solms.) smooth (A1) and the water hyacinth
(Eichornia grassipes (Mart.) Solms.) rough (A2) and the second factor is the
source of an organic activator which consists of four level without the type of
activator (control) (B0), Mol fruit with vegetables (B1), Tape, tempe, with
yakult (B2), and EM4 (B3). The parameters observed were comparison of
temperature, pH and C/N ratio.The results of research showed that of water
hyacinth (Eichornia grassipes (Mart.) Solms.) on some kind of local
microorganisms (MOL) as fruit with vegetables (B1) MOL, Tape, tempe, with
yakult (B2) MOL, and EM4 (B3) MOL, gives good the results of temperature, pH
and C/N ratio of compost.
Key word: Organic fertilizers, activators, the temperature of pH,
the ratio of C/N
