PEMBUATAN DAN UJI MULSA ORGANIK LEMBARAN DARI BAHAN BAKU ECENG GONDOK (Eichhornia crassipes (Mart.) Solms.) DAN PELEPAH PISANG (Musa paradisiaca L.)
ABSTRACT: A randomized block
design experiment was carried out to evaluate the quality of an organic sheet
mulch made from the biomass of hyacinth (Eichhornia crassipes (Mart.) Solm)
combined with banana (Musa paradisiaca L)
bunch with a decomposition agent of urea or caustic soda. The hyacinth (H) and banana (B) bunch biomass
were chopped and mixed at the H:B ratios of 10:0, 9:1, 8:2 and 7:3. After a
further size reduction with a warring blender, the biomass mixture (600 g) was
decomposed by boiling it for 30 minutes in 2 L of water added with 6 g of
either urea or caustic soda. The treated biomass was then washed, dewatered
by pressing and air dried to form a sheet mulch. It was found that both
the normal tense and tensile strength of the sheet mulch varied with the
biomass ratios and the decomposting agent. The soda treated mulch made from the
biomass ratios of of 9:1 and 8:2 showed a higher normal tense and tensile
strength than those treated with urea or with other biomass ratios. The yield
as well as the water absorption holding capacity increased with the banana
biomass. The best organic mulch sheet
was obtained from the use of water hyacinth : banana bunch (8:2) treated with
1% caustic soda.
