PENGARUH VARIASI DOSIS LARUTAN DAUN PEPAYA (Carica papaya L.) TERHADAP MORTALITAS HAMA KUTU DAUN (Aphis craccivora) PADA TANAMAN KACANG PANJANG (Vigna sinensis L.) SEBAGAI SUMBER BELAJAR BIOLOGI
Abstract: One
of the obstacles
that farmers faced
is the presence
of leaf pests.
The effort to reduce the use of synthetic pesticides is necessary to
look for the alternative ingredients derived from plants that have potential as
plant pesticide. One of them is papaya plant. The purposes of this study are
(1st) to know the whether there is effect of variant dose
of papaya leaf
solution toward mortality
of leaf pests.
(2nd) to know whether
the dose of
papaya leaf solution
is the most
appropriate for leaf
pests mortality. (3rd) to arrange the biology learning source to senior
high school students of tenth grades in even semester. This research was an experimental design and
this research was completely
randomizes design (RAL)
by using five
times repeats by using variant doses in the control
treatment, 15gr/L, 20gr/L, 25gr/L, 30gr/L, 35gr/L. The data
were analyzed by
using non-parametric test
one-way ANOVA. The
results showed the percentage of the leaf pests from the lowest to the
highest are control=0%, 15gr/L=64%,
30gr/L=68%, 20gr/L=76%, and
35gr/L=92%. From the
result of discussion and
conclusion that there was significant influence on the variant dose of papaya
leaf solution toward mortality of leaf pests by testing the hypotheses that H0 was rejected
and H1 was
accepted. Because, X2count
18,25> X2 table
9,49 at )05,0( and X2 count
18,25 > X2table 13,3 at )01,0( on the chi-square table. Based on this
result of the research and discussion, it can be conclude that (1st) there was significant
influence on the
administration of papaya
leaf solution, toward mortality of leaf pests, it was gained
the coefficient H=18,25 > chi-square value 9,49 at α level of 0,05 and 13,3
at α level 0,01. (2nd) at dose 35gr/L of papaya leaf solution was the best dose
to mortality of the leaf pest. (3rd) the result can be used as a source of
biology learning to senior high school students, tenth grades in even semester
for the worksheet of
Students Activity (LPKS)
about the interaction
of ecosystem of the
pests and diseases in plants.
