Abstract:
Community's trend in the use of plant for medical treatment or beauty has opened
a chance in the biopharmacy agribusiness in Indonesia. Turmeric as one of a rhizome
plant has an important role in medicinal plant industry. Quality of turmeric's product is
definited by the content of curcumin, performance and size of rhizome. Most of all,
curcumin's quality depend on interaction between the genetic factor and growth
environment.
This research was aimed to study the relation between rhizome and bioactive
turmeric production and land quality in order to determine land evaluation criteria and to
evaluate land evaluation criteria on some samples from Bogor.
This research was an extention from an earlier studies which were done at
Icaranganyar Central Java, Ngawi and Lamongan East Java in 2004, and followed by
other studies in Sukabumi, Indramayu, Cianjur and Bogor West Java. Soil and bio active
analysis were conducted in Soil Chemical and Fertility laboratory in Department of Soil
and Land resourcces and in Biopharmacy laboratory IPB.
Results of the study indicated that the relation between rhizome and curcumin
production and land qualities spread with such particular pattern which is convined with
boundary line. By making the production classes for S2, S3 and N with each class values
by 85%, 60% and 30%, where 30% is the break event point of productivity. The limits of
every classes in the land evaluation criteria for each land qualities can be made by
creating a projection of intersection between the boundary line and the yield cut off.
The land evaluation criteria that was an exploration study base, did not evaluate
entirely all of the crop requirements. More data from a wider soil agroclimate zone
therefore would be greatly appreciated.
