Abstract
The role of organic fertilizer is in the addition of organic matter of the soil and serves as a
source of plant nutrients, improving the soil porosity which improves the soil aeration and
drainage, increasing the activity of soil microorganisms, improving the structure and texture of
the soil, improving soil chemical and stabilizing soil aggregation. Besides maintaining soil
fertility, it also has the properties to hold water longer and does not pollute the environment.
Organisms that can be used as a biofertilizer include algae, while Trichoderma pseudokoningii
were supposed to function as biopesticide as well as decomposer that will decompose algae in
to compost organic biofertilizer.
Some Types of blue-green algae such as Cyanophyceae sp. Has the ability to perform
photosynthesis and nitrogen fixation and is advantageous to become the mainstray of this
study and as a source of biological nitrogen derived from natural biological body is renewable.
On the other hand, Trichoderma sp is a natural decomposer that contains cullulase enzymes.
The enzyme cellubiose (β-glucosidae) and chitinase enzymes can work Synergistically to
accelerate the process of weathering organic matters. Moreover, Trichoderma sp. Potentially
can be used to control pest and diasease and are safe for the environment and improve plant
resistance by the inductionmechanism of phytoalexins production or increase plant resistance
against the pathogen. The use of Trichoderma sp as decomposers of organic as well as as
biological control and algae as organic fertilizer, which we call TrichoAlgae, is expected to be
effective and has the potential to burn the algae into organic fertilizer, as well as a biological
control against the pathogen. Based on results of an earlier research, by making innovation to a
new formulation called Trichoalgae organic fertilizer it is expected to obtain a product which is
the synergy of the potential and advantages of algae as an organic fertilizer combined with
Trichoderma as decomposer and biological control agent, which can later be expected to
contribute effectively to enhance plant growth and simultaneously improve plant resistance
against the pathogen attack
