Potential gewang In the province of East Nusa Tenggara


gewang1Gewang including monocarpic plants, flowering terminal, and finishes flowering and fruiting will die. Age gewang fruiting plants is estimated at over 15 years. Number gewang thousands of seeds and fruit when ripe will fall and spread under the tree. Most seeds will germinate and grow into young gewang plant. Spread to the surrounding land, through water during the rainy season that brought the seeds gewang and dispersed away from the parent tree. If you already live and become young plants and not yet trunked gewang above ground level, it is very difficult to eradicate. Although exhausted slashed and burned, some time later, new shoots will emerge again. This is because the defense allegedly gewang roots deep enough into the ground, then during the growing point is not dead yet will always grow again, unless crushed with a crowbar growth point. Gewang tolerant plants and has been adapted in dry land dry climate such as NTT, and it has enormous benefits for society, it is very likely to be developed with the right touch technology. For residents of East Nusa Tenggara, gewang plant plays an important role in his life because almost all parts of the plant is used, starting from the stem, stem, leaves, flowers and fruit. If other types of palms mainly used part generative (flower and fruit), the vegetative part of the plant used gewang, starting from the stem, leaf and stem of the leaf blade, as well as a small portion of the juice and sugar flowers gewang. Gewang rods used primarily empelurnya section called putak for animal feed, ie cattle, goats, pigs, chickens and horses. Empelur gewang as well as rods can be processed to be taken sago starch as flour foodstuff. As animal feed gewang stems peeled and chopped empelurnya to reach the size of 3-5 cm. Most houses in coastal villages made of stems, stem and leaf gewang. Gewang leaf midrib is used as a hedge to protect the crops from nuisance pets such as cows, pigs and goats. Empelur rod gewang (putak) which is rich in nutrients are used as animal feed, and the drought situation is also used as food ingredients (starch gewang) for the majority of the population.

Gewang problems in plants is still very little research results especially technology providing plant material, cultivation and post-harvest. In addition, the technology gewang seed germination and preparation is needed to support the preservation of germplasm gewang. Cultivation technology for accelerated growth and harvest, processing technology tools for supply of animal feed more efien and easy process. If not conserved and utilized gewang plant is, the more displaced by land conversion for other commodities and residential and office buildings. Gewang plants need to be maintained and preserved in certain areas, so that the public can still be used as animal feed such as cattle in order to support the acceleration of beef self-sufficiency in the future.

The results of studies that have been reported that putak production can reach around 663 kg / tree. Putak number can meet additional food for about 430 goats or 65 head of cattle for 3 days. Giving putak plus 3% urea can suppress lose weight in the dry season and increase the weight of cattle and goats in the rainy season. Information from BPTP NTT researchers that putak feeding to cattle should not exceed 7 kg / head / day. Experience in the provision of over 10 kg of cow intestine causing injury, and causes cattle to die. Empelur gewang rods that have been peeled bark, sold most of the population in the form of rods empelur pieces of various sizes and price ranges depending on the size of the pieces Rp.7.500 to Rp. 30,000 per piece. Empelur piece rod is used as putak for livestock, especially in the dry season, because green grass is no longer growing.

  • Midrib Gewang
  • Leaves Gewang
    The young unopened leaves used for weaving, and old leaves are used for roofs, walls and wicker. Gewang sticks of leaves can also be made of sticks and rope.
  • Flowers Gewang
    Gewang interest can be tapped to produce sap, and sap is cooked into sugar gewang. In principle gewang sugar quality is almost the same with palm sugar, coconut and palm, but the sweetness was not as sweet as sugar and palm, and there is a distinctive flavor gewang.
  • Seed Gewangbiji_gewang
    Gewang seed crushed by society for materials traditionally fishing.

It can be concluded that the actual gewang plant is very tolerant and adapted very well in the lowlands (<100 m asl), availability of sufficient groundwater is available, and can survive in the long dry season.
