Introduction

Orangutan (Pongo pigmaeus) is an

extinct primate animal. Its status as

the extinct animal requires more

intensive treatment to maintain their

existence in Indonesia especially at

Tanjung Puting National Park.


It is necessary that the rehabilitating

methods for infants who lost the

parents should be established. We

must the a lot of data to keep their

development and well conditions.

Therefore, it is important to clarify the

energy requirement and the food

nutritional contents, and then establish

the supplemental feeding methods.


Method 1

To estimate the quantitative nutritional

content

Measuring 35 orangutan`s body weight

By estimating the adequate nutritional

for orangutan using Fowler`s formula

1.5 MEC (Metabolic Energy Coefficient)

= 1.5 x Basal Metabolic Rate (BMR)


Method 2

Converting its nutritional needed (protein,

fat, vitamins and minerals) in to the

Recommended Nutrition Intake for human

the information of how many grams

bananas, pineapples, milk, cerelac and

sugar had been consumed

estimating their nutritional content

based on Indonesian List of Food

ong>Nutritionalong> Composition

The evaluation of the food cost per day or

the consumption cost for each age class to

progress orangutan and their habitat.

The comparison of nutritional

requirement for infant child, juvenile,

and adult orangutans

1. Infant-child class

exceeded 37 %

2. Juvenile class

lacked of 35 % of their needs

3. Adult class

lacked of 76 % of their needs


Discussion

1. The rehabilitating area in Centre

Rehabilitating Orangutan at Tanjung

Puting give the opportunity for orangutan

to grow up by themselves and reproduce.

On the first step at rehabilitation, Forest

Ranger always take care and helpful for

orangutan. As the new comer become

adaptation for the new habitat, they are

keeping in their ecological behaviors.


2. Supplemental feeding costs per day for

orangutan were infant-child 137 %,

juvenile 65 % and adult 24 %. The

dependent rate for natural foods of infantchild

is very low, juvenile is middle and

adult is high. Its suggests that the

orangutan adapted step by step for

natural conditions, as they growth.


3. I must determine juvenile and adult

orangutan`s foods in the forests. And then

I research the nutritional contents,

seasonal changes in their body weight and

the nutritional capacity in the forests.


4. I hope that Forest Ranger do not supply the

supplemental foods again for juvenile and

adult, because they have to take their life by

themselves.

Firstly, we have to gain the social

consensus for orangutan conservation.

Second step, we have to become good

natural habitat for orangutan.

Now, natural forest at Tanjung Puting

National Park are poor habitat for

orangutan`s life. There are many illegal

logging and human activities. I think that we

can conserve the orangutan if the area at

Tanjung Puting National Park will be increase

on the large scale and sustain the area with

the preference foods for orangutan.


5 a. The density of orangutan is low at

Tanjung Puting, one or two

individuals per two square

kilometers in most area.

b. Most field researchers have noticed that at the

time of fruiting of durian, orangutan assemble

in the durian tree in large numbers. It is

certainly an indication of it being a favorite for

the orangutan palate.

The fruiting season for the durian is actually

rather long, from August through to December

and peaking in the month of October.

This implies that every individual territory

might contain one durian tree that the territory

was chosen perhaps because of its presence.
