Abstract

Abstract Indonesian konjac (IK in brief), also known
as Amorphophallus muelleri Blume in Latin, is a wild plant
growing in several places in Indonesian archipelago. The
tuber of IK plant contains a compound called glucomannan
which has high economic value since it can be used as a
raw material in many industries such as medicine, cosmetic,
paper, textile, synthetic rubber, and filming industries. Due
to this economic value, this study was carried out in order
to increase the productivity of glucomannan and bring IK
into mass cultivation. For this purpose, the objective of this
study is to increase the productivity of IK tubers by
increasing the speed of seeds gemination process and by
decreasing the dormancy period. Meanwhile, bringing IK
into mass plantation will be put as a package of campaign
program to educate people. To speed up the germination
process and to decrease the dormancy, the method used in
this study period is by improving the soaking process of IK
seeds using KNO3 solution. Its effects were investigated
using a completely randomized design (CRD) with three
treatments, namely, concentration of the solution, soaking
time, and plant age. Then, data were collected and analyzed
statistically using general linear model, analysis of
variance and Duncan’s multiple range test. The results
indicate that soaking in that solution has a significant effect
on shortening the time period for seeds to germinate. Its
optimal effect was reached for 3,000 ppm of concentration
with soaking time 3 hours at 14th days after plantation
(DAP). Moreover, in terms of dormancy period, that
solution has reduced from 5-6 months to 2-4 months. These
findings were significantly support the effective use of
KNO3 solution to answer the objective of research. The germination period has been reduced from 3-6 months to
around 14 days. To the knowledge of the authors, based on
the literature used in this study, these are unprecedented
findings. Therefore, hopefully, it could contribute to the
development of konjac-based industries and to the
literature of konjac particularly Indonesian konjac.
