|Abstract: ||The back ground of this research are exploiting of agricultural waste
produce (Oryza sativa. L and Eichhornia crassipes) as source of fibre that has
very much cellulose, so it can be exploited as the basic substance to make art
paper. Tapioca is the glue type that can strengthen and conserve the art paper.
This research has purpose to get the basic substance proportion between
Oryza sativa. L and Eichhornia crassipes by increasing tapioca proportion as the
glue that can produce high quality of art paper and want to know the calculation
of the basic coast production (Harga Pokok Produksi/ HPP) of the paper
industries which made from those substance.
The research planning which used by the researcher was Group Random
Planning (Rancangan Acak Kelompok/ RAK) with two factors and every treatment
was done up to three times. The first factor was the proportion of the basic
substance (Oryza sativa. L and Eichhornia crassipes) (A) that consisted of 5 level,
they were: A1= (90%:10%), A2= (80%:20%), A3= (70%:30%), A4= 60%:40%),
A5= (50%:50%). The second factor was the glue of tapioca (B) that consisted of
B1= 10%, B2=15%, B3= 20%. The sensory test of the art paper using the
Friedman test and the BNJ test by Microsoft Excel 2000 program and SPSS
version 12, if there are real influence among treatment, at the best treatment the
sensory test, be done analysis of the best treatment alternatife election with index
effectifity method, while physical test using the manner analyse (ANOVA) to know
the existence of real influence.
The result of research the sensory test at the best treatment alternative art
paper with the proportion of Oryza sativa. L (60%) and Eichhornia crassipes
(40%), the tapioca glue 15%, product value 0.89. The result of research at art
paper pysical test has the highest result at proportion of Oryza sativa. L 90% and
eichhornia crassipes 10%, the tapioca glue 15%, product value 0,96, with the
value of pulling endurance 3,64 (kN/m), the torning powerfull 1590,67 (mN),
gramatur 187,01 (g/m2
), and the sucrose content of sample 45,16%. The product
more selected to producted because the product has the highest physical value, so
the product more compatible was used as substance to make handycraft whithout
coating. The substance do not to importance of sensory parameter.
