OPTIMASI PENGGUNAAN NaOH DAN TAPIOKA PADA PRODUKSI KERTAS SENI DARI PELEPAH PISANG
ABSTRACT: The main purpose of
this research was to find out the optimum concentration of NaOH and cassava
starch on the production of art paper from the banana leaves. The central
composite design in Response Surface Methodology was used with two factors i.e.
NaOH (b/v) and cassava starch concentration, and 5 times repetition at central
point. The data was analyzed using
design expert DX7.0.3, the organoleptic test used t-test, and financial
analysis was conducted on HPP, BEP, PP, and NPV. The result showed that NaOH
and cassava starch concentration affected the tearing strength value and
tensile strength. The optimum process reached on NaOH concentration of 0.50%
b/v and the cassava starch concentration of 0.39% b/v. The organoleptic test showed that most of the
panelist preferred paper appearance and the thickness. By the investment of Rp. 45.9198.419,00 and
500 sheets production capacity per day, the HPP value was Rp. 427,92. With the selling price of Rp. 599,06 per
sheet, the financial analysis was as followed: BEP was 47.514,38 sheet that
equal to Rp. 28.465.353,32 or 32.99%; PP was 2 years 11 month and 6 days, and NPV was Rp. 56.474.249,06.
