KEMAMPUAN EKSTRAK DAUN BANDOTAN (AGERATUM CONYZOIDES L.) DALAM MEMPERTAHANKAN KESEGARAN BUAH TOMAT(SOLANUM LYCOPERSICUM L. VAR. PERMATA)
ABSTRACT: The tomato (Solanum
lycopersicum L.Var. Permata) is one of the horticultural crops that contain
vitamin C with potential for health. During the ripening process in storage,
the tomato will experience a more rapid weight loss and decay caused by
respiration and bacteria. The storage life of the tomato can be extended by
adding edible film from plant extracts that contain secondary hydrocolloid and
metabolite compounds. This research aimed to find out the effect of the
bandotan (A. conyzoides L.) leaf extract of different concentrations on the
freshness of the tomato (S. lycopersicum L.) and to find out the best
concentration of the bandotan (A. conyzoides L.) leaf extract to maintain the
freshness of tomato (S. lycopersicum L.). The research was carried out from
February to April 2015. The experiment used in this research was a completely
randomized design. The concentrations of the bandotan extract used consisted of
4 treatments i.e. 0 ppm (P1), 10 ppm (P2), 20 ppm (P3) and 30 ppm (P4). The
research findings indicated that the 30 ppm treatment was better at a weight
loss parameter of 8.67 and a density of bacteria at 70.5 x 103. The treatments
of 10 ppm, 20 ppm and 30 ppm had the ability to maintain the content of vitamin
C.
