the East Java Municipality of East Java has not intend to cut the Bintaro Tree suspected of having toxic contents. Because the tree is also known as Cerbera Manghas is suitable to live in critical areas, or land that can not be planted with other types of plants.
"I have heard (Bintaro, a poisonous tree), just so far we have never done any special research related to the content of toxins in the tree," explained Head of Cleansing and Gardening Agency (DKP) Surabaya Chalid Buhari to Journalist, Surabaya, Tuesday (24 / 3).
He acknowledged, Bintaro Tree grows on the pingir protocol road in Surabaya, has been since more than 10 years ago.
"Before I enter DKP, this tree already exists and grows in Surabaya.This tree has hundreds more in all areas in Surabaya.Now, this tree is also used as a mixture for fertilizer," he continued.
Related to the selection of Bintaro Tree as the lung planting of the city, because it has leaf round eggs with dark green color arranged together, but it can also grow on the critical land.
"This tree is suitable for critical areas, that is, if other types of trees can not grow fertile planted on the land, the Tree of Bintara can live there," he exclaimed.
While the problem of poisonous dangers of Bintaro Tree, Chalid rate is still safe. However, he promised not to increase the population of the tree in Surabaya.
"I think so far it is still safe, as long as it is not consumed by humans, because of its poison content, maybe we will not increase the population of the tree in Surabaya," he said.
Previously, a plant researcher Trisno Wardani, a resident of Jalan Darmo Permai Selatan, Surabaya, had done research on a tree with the scientific name of Cerberus, which in Greek mythology is known as the name of a ten-headed dog.
In his research, Trisno claimed to find a toxic substance in plants that have flowers crown and smell of it.
He said, fruit trees resemble mango, other than toxic can also damage the surrounding environment. From the results of his research, plants located at a distance of two meters next to the Bintaro Tree will die due to lack of water."We have just done a laboratory test at Sucofindo," said Trisno at his home on Saturday (21/3).
He pointed out, pond water full of fish, can die within seconds if Bintaro Tree leaves inserted in the pond. Water polluted by the leaves of Bintaro, within seconds, the wiggler in the water immediately dies.
"If planted near ponds or ponds, when the leaves fall into the water, fish in the pond, can be sure to die," he gave an example.
"The roots of this tree also contain substances that can harden the soil, if planted in the streets of the protocol, then it will slow the water uptake in the event of flooding in the city," he continued.
Therefore, continued Trisno, there is good if the City Government of Surabaya no longer plant Bintaro trees again on the sidewalk. "Especially so far, the collapsed leaves are collected by the Gardening Agency and recycled with other leaves to make fertilizer."
In fact, still he said, if the leaves are mixed with leaves that will be used as fertilizer, it will not fertilize, it will make the soil harder. "The roots alone have made the ground hard, let alone sap leaves," he said.
He also assures, in Bintaro Tree will never grow Benalu. Even caterpillars and earthworms, just smell the scent of this tree, will not dare to approach.
Bintaro dispersal naturally in the tropical Indo Pacific region, from Seychelles to French Polynesia. Bintaro is often part of the mangrove forest ecosystem. In Indonesia Bintaro is now used as a reforestation plant of coastal areas and the shade of the city.
The leaves and fruits of Bintaro Tree contain substances that can affect the heart, a glycoside called cerberin, which is highly toxic. The sap has long been used as an arrow or tulup poison to hunt. The poison is reportedly used for suicide or killing people. [cob]
