It has many advantages: Once hailed as a 'wonder material', plastic is now a serious worldwide environmental and health concern, essentially due to its nonbiodegradable nature. In India, the plastic industry is growing phenomenally. Plastics have use in all sectors of the
Gutta-percha or in Indonesian known as "Getah Perca" is one of native plants of Indonesia. Gutta percha belongs to a rare species of flora in Indonesia. Historically, Gutta percha Indonesia has a history that can not be forgotten.
According to Collins Dictionary Online, Gutta-percha is any of several tropical trees of the sapotaceous genera Palaquium and Payena, esp Palaquium gutta. Another definition is a whitish rubber substance derived from the coagulated milky latex of any of these trees: The word gutta-percha comes from the plant's name in Malay, getah perca, which translates as "percha latex".

Has a small white flower in one bud. Has a fruit measuring cm containing seeds, but in some species do not appear to have fruit. However, Gutta-percha is now believed to be increasingly rare and almost extinct in Indonesia. Gutta Percha entered the world market circa after being known to possess suitable properties as an insulation material for the seabed cables.
As we go through the history of Gutta-percha, there is an interesting story about its discovery. But the honour of introduction of this material goes to Dr. William Montogmerie, who was a medical officer in Indian service.
He was the first to appreciate the potential of this material in medicine and for which he was awarded the gold medal by the Royal society of arts, London in He obtained samples and realising its usefulness for making surgical appliances sent samples to the Medical Board in Calcutta.
He also sent samples to The Royal Society of Arts and by introducing this Malayan gum to the western world for the manufacture of surgical appliances he had placed in the hands of British industry the first really useful plastics material — Gutta-percha.
A sample of Gutta-percha came into the hands of Thomas Hancock, he showed it to his brother Charles, a professional artist also interested in commercial projects, who was experimenting with bottle stoppers. Arounddue to an increase in the need for Gutta-percha, and judged sufficient experience at the planting of previous experiments, the Dutch Colonial Government decided to build the Gutta Percha Tjipetir State Plantation by planting a Gutta Percha production plant.
Here was a massive exploitation by the Dutch colonial and British imperialism to dominate Gutta-percha in their colonies. From toan area of ha was added, which in the planting of Gutta-percha expanded again by ha. The total area of Gutta-percha in Tjipetir Plantation was then about 1, ha.
It was not until that the administrators agreed that a factory could be established on the initiative of Tromp de Haas [4] to begin processing product from the plantation.

It was used in the 19th and first half of the 20th centuries to insulate telegraph cables on the seabed. But a reliable source mentions that this block of "Tjipetir" came from the Miyazaki Maru ship.
