Waste is a consequence of human activities. The increase of human population and economic
growth can cause problem in waste handling, especially those containing organic ingredients.
This kind of waste, if is just dumped and not appropriately managed will invite animal vectors
carrying disease agents as well as disturb the aesthetic values. This study utilized vegetable
wastes and coconut fibre wastes dumped by sellers as liquid organic fertilizer (which are called
“Skimsa”) fo Ipomoea reptans. This study was aimed to determine whether the spraying of
“Skimsa” and organic liquid fertilizer brand "X", which are sold in the market, give different effect
on the leaf number and the weight of that plant, by conducting a quasi experiment following
post test only with control group design. There were 30 polybags for each treatment group and
the fertilizers were given in four weeks. The data from observation were analysed by using
independent t-test at 95 % confidence level, and the results showed that the average number of
leaf (p-value=0,063) and the weight (p-value=0,18) of Ipomoea reptans yielded from both organic fertilizers were not significantly different. Therefore, it can be concluded that liquid organic
fertilizer made of vegetable waste and coconut fibre waste has same effectiveness with that of
brand "X".
