PENGARUH SUHU TERHADAP KARAKTERISTIK PENGERINGAN REBUNG BAMBU TABAH (Giganthochloa nigrociliata Kurz)

Abstrak

Bamboo tabah shoots is a product with high level of water which is 91%
and easily damaged after harvested, so the advanced handling was need to keep
the quality and storage period. One method is by drying. The purpose of this
research is to study the effects of temperature the drying characteristics of bamboo
tabah shoots. According from this research, bamboo tabah shoots was dry by oven
and used 5 points of temperatures as the way of treatment. This research was
using data from weighing the mass of material within drying process to obtain
decreasing of moisture content and drying rate in bamboo tabah shoots. The
temperature of drying that used in this research were 50˚C, 55˚C, 60˚C, 65˚C, and
70˚C. From this research known that the drying temperatures have the effects to
the result of the drying characteristics, but have no effect to the physical
characteristics of drying bamboo tabah shoots. The lowest drying rate that found
from the objects that was dried using 50˚C is 31,82%db/hour which was dried for
32 hour with the final water level 9,38%wb and the highest dried rate found from
the object that was dried using 70˚C is 72,04%db/hour which was dried for 18 hour
with the final water level 9,74%wb. The drying rate increased by the increase of
temperature.
