Abstract

Coppicesof Eucalyptus pellita have the potential to produce seeds, so it takes a vegetative plant propagation by cuttings to meet the supply of seed planting. One of the factors that affect success rate of cuttings is the content of plant growth regulator (PGR) as Naphthalene Acetic Acid (NAA) from the category of auxin. This research aim to determine effect and exact concentration of PGR containing active NAA toward the growth of coppice cuttings. This research used a completely randomized design (CRD), which consists of 4 treatment (P0 = Without PGR containing active NAA; P1 = PGR containing active NAA 25%; P2 = PGR containing active NAA 50%; P3 = PGR containing activeNAA 75%), with 3 replications and 10 cuttings each. The results were analyzed using variance and if it is distinctively different it will be continued with Duncan  New's Multiple Range Test on the level of 5%. The results showed that giving plant growth regulator containing active NAA not significantly yet toward the growth of Eucalyptus pellita coppice cuttings. Giving PGR containing active NAA at a concetration of 25 % and 75 % concentration inclined to be better toward thegrowth of Eucalyptus pellitacoppice cuttings.   Keywords: Cuttings, Coppice, Eucalyptus pellita, Naphthalene Acetic Acid(NAA)

Abstract

The sumatran elephants including herbivorous animals that require the availability of sufficient food forage habitat. The sumatran elephants also need vegetated habitat trees for supplementary food to meet the needs of the mineral calcium to strengthen bones, teeth, and tusks. Digestion is not perfect, elephants need food very much is 200-300 kg of biomass per day for each adult elephants or 5-10% of their body weight. Elephants eating behavior is very dominant behaviors performed of Sumatran elephants. The percentage difference eat elephant behavior likely influenced by body weight, gender, age, differences in habitat area, number and type of feed available. The sumatran elephants uses their trunks to pick up food, starting from choosing foods perceived with its trunk up food withdrawn or revoked then cleaned with a wave of food into the body of the elephants when it is completely clean of dirt, the elephant will start to eat the food with his mouth.Type of food usually eaten for at pasture in nature include: young leaves of various herbaceous plants wild roots and liana, young rattan and shoots rattan, bark of tree species at a sampling rate, bamboo shoots and young thorns, grass reed and all parts of wild banana.   Keywords: Behavior, Sumatran elephants, Tesso Nilo National Park
