EKSTRAK KELOPAK BUNGA ROSELLA (Hibiscus sabdariffa L.) SEBAGAI PEWARNAAN ALTERNATIF ALAMI PREPARAT SECTION TANAMAN CABE MERAH BESAR (Capsicum annuum L.)
Abstract: Plants section
slides are a method of making mikroteknik slides intended for objects that are
big and bold on the plant, so that the tissue can be seen under a microscope.
Observations on the tissue of plants section slides big red chili (Capsicum
annuum L.) will be more easily if use a dye to staining the tissue. The aim of
this staining is to clarify the various tissues of plants, so that it can be
distinguished and being reviewed with a microscope. Exploration of exploiting
alternative coloring matter of being cheaper and has a high affinity towards
cell components is very important, so the use of extracts of rosella petals
flower (Hibiscus sabdariffa L.) as alternative natural dyes are expected to
produce natural staining alternative to replace staining is usually used. The
aims of this research to know the effect of granting the concentration extract
of rosella petals flower (Hibiscus sabdariffa L.) as a natural dye to the
quality of plants section slides Capsicum annuum L. and to know and compare
quality of the picture of the plants section slides Capsicum annuum L. results
of extract of rosella petals flower (Hibiscus sabdariffa L.) natural staining
with results of safranin synthetic staining.The type of this research is
experimental research. This research was conducted in the Laboratory of Biology
of University of Muhammadiyah Malang which took place on March 11-March 15,
2014. This research used the concentration of extract of rosella petals flower
is 30%, 40%, 50%, 60%, 70%, 80%, 90%, and 100% with 3 times repeats. Data
collected by direct observation and documentation directly from the camera by
using a microscope. Data were analyzed with descriptive qualitative analyses
and descriptive quantitative from observations results and documentation of the
results directly from the microscope. The results showed there is the staining
effect of various concentrations of the extract of rosella petals flower to the
quality of plants section slides Capsicum annuum L. Quality of plants section
slides Capsicum annuum L. results of natural staining from extract of rosella
petals flower has a good quality picture of slides. Comparison of the quality
of the plants section slides Capsicum annuum L. results of extract of rosella
natural staining petals flower did not vary much with results safranin
synthetic staining.
