POTENSI EKSTRAK KASAR ENZIM BROMELIN PADA BONGGOL NANAS (Ananas comosus) SEBAGAI KOAGULAN ALAMI LATEKS (Hevea brasiliensis)
Abstract: This research aimed
at discovering the optimum concentration of crude extracts of pineapple as
natural latex coagulant and determining the effect of crude extracts of
bromelain enzyme on the quality of coagulum produced. The research was mainly
conducted at the Laboratory of PT. Riau Crumb Rubber Factory, in May and July
2016. The study used a completely randomized design (CRD). The design consists
of 6 treatments of coagulant substance with 3 times repetitions with the result
that 18 experimental units were gathered. The data were analyzed using analysis
of variance (ANOVA), and were they found significant, Duncan's New Multiple
Range Test (DNMRT) at the level of 5% was further used. The results of the
study showed that the optimum concentration obtained is by adding K2 (1,5%
crude extracts of pineapple with enzymes activated). The addition of complete
enzyme crude extract of pineapple proved to significantly affect the pH value,
dry rubber content, ash content, dirt content, however the values of Po and
PRI.
