SUMMARY
LATIF SOFIANA NUGRAHENI. Food preference of long tailed macaques in
Telaga Warna, Bogor, West Java. Supervised by KANTHI ARUM WIDAYATI
and BAMBANG SURYOBROTO.
The long-tailed macaques (Macaca fascicularis = crab eating monkey)
have broad geographic distribution areas and they can also live in various altitudes
and habitat. Consequently, they have broad ecological plasticity to adapt to
different environments, particularly in feeding ecology. These conditions make
the macaques have a food preference to certain foods.
The macaques typically eat in the food patch which is generally feeding
sites or food points. They would look for food patches that have abundant food in
the form of an environment that supports the availability of food. In Telaga
Warna, the macaques forage in three feeding sites (I, II and III feeding site) and
they can find natural and artificial foods. However, there are currently
environmental changes that also lead into behavior and diets changes of
macaques.
This study reported that during the last two years, food preference of the
long-tailed macaques in Telaga Warna turned into artificial food equipped with
knowing feeding site preference in a food patch.

A study of food preference was conducted in Telaga Warna Bogor, West
Java Indonesia from June to September 2014 in group A (nmax = 49 individu).
Daily activity of the macaques was observed using scanning method, and food
preferences were determined by recording the feeding duration and party size, at
every feeding site in a food patch.
The results showed that food preferences of long-tailed macaques in
Telaga Warna turned into artificial food, and they spend more time at the feeding
site II which have the better quality food than feeding site I and III. The changes
of dietary and behaviors are influenced by changes in the environment followed
by increasing in number of visitors. In Telaga Warna, this matter becomes a
concern because it has a tendency to increase in number of visitors each year.
Thus, it need to be considered, especially for the tourist attractions that attract
visitors in large numbers, so that awareness will be raised for controlling the
management of the tourist area in order to maintain the balance of nature.

RINGKASAN
LATIF SOFIANA NUGRAHENI. Makanan pilihan monyet ekor panjang di
Telaga Warna, Bogor, Jawa Barat. Dibimbing oleh KANTHI ARUM WIDAYATI

dan BAMBANG SURYOBROTO.
Monyet ekor panjang (Macaca fascicularis = crab eating monkey)
memiliki area distribusi geografis yang luas dan mereka juga dapat tinggal di
ketinggian dan habitat yang bervariasi. Akibatnya mereka memiliki plastisitas
ekologi yang luas. Kondisi ini membuat monyet ekor panjang memiliki makanan
pilihan untuk makanan tertentu.
Monyet ekor panjang biasanya makan di dalam food patch yang terdiri dari
feeding site atau food point. Mereka mencari food patch yang memiliki makanan
berlimpah di lingkungan yang dapat mendukung ketersediaan makanan. Di Telaga
Warna, monyet ekor panjang mencari makan di tiga feeding site (feeding site I, II
dan III) dan mereka dapat menemukan makanan alami dan buatan. Namun, saat
ini terdapat perubahan lingkungan yang mempengaruhi perilaku dan pola makan
dari monyet ekor panjang.
Penelitian ini melaporkan bahwa selama dua tahun, makanan pilihan dari
monyet ekor panjang di Telaga Warna berubah menjadi makanan buatan yang
dilengkapi dengan mengetahui feeding site pilihan di dalam food patch.
Penelitian tentang makanan pilihan ini dilakukan di Telaga Warna Bogor,
Jawa Barat Indonesia dari bulan Juni sampai September 2014 pada group A (nmax
= 49 individu). Aktivitas harian monyet ekor panjang diamati menggunakan
metode scanning, dan makanan pilihan yang ditentukan dengan mengetahui durasi

makan dan ukuran partai, di setiap feeding site didalam food patch.
Hasil penelitian menunjukkan bahwa makanan pilihan dari monyet ekor
panjang di Telaga Warna berubah menjadi makanan buatan, dan mereka lebih
banyak menghabiskan waktu di feeding site II yang memiliki kualitas makanan
lebih baik daripada feeding site I dan III. Perubahan dari pola makan dan perilaku
dipengaruhi oleh berubahan lingkungan yanhg diikuti oleh pertambahan jumlah
pengunjung. Di Telaga Warna, hal ini menjadi perhatian karena memiliki
kecenderungan peningkatan jumlah pengunjung setiap tahun. Dengan demikian,
perlu diperhatikan, terutama untuk tempat-tempat wisata yang dapat menarik
pengunjung dalam jumlah besar, sehingga akan membangkitkan kesadaran untuk
mengendalikan pengelolaan kawasan wisata untuk menjaga keseimbangan alam.

INTRODUCTION
The long-tailed macaques (Macaca fascicularis = crab eating monkey)
have broad geographic distribution areas in the tropics of Southeast Asia, covering
the southern part of Bangladesh, continent of Southeast Asia, Malayan Peninsula,
Sunda Archipelago, Nichobar Islands, and the Philippines. In Indonesia, M.
fascicularis are distributed in Kalimantan, Sumatra, Riau, Bangka-Belitung,
Banyat, Karimata archipelago, Anabas, Tambelan, Natuna, Simalur island, Nias,
Java, Bali, Matasuri, Bawean, Maharua, Timor, Lombok, Sumba, Sumbawa and
Flores (Fooden 1995).

M. fascicularis could live in various altitudes from lowland forest near the
sea to the highest mountain forests. They also may be found in several places with
an altitude above 1000 meters above sea level, for example in Malaysia they are
found at an altitude of 1200 meters above sea level, 1800 meters above sea level
in Borneo, 2000 meters above sea level in Sumatra and Java (Fooden 1995;
Fooden 2006). Habitat of M. fascicularis includes mangrove forests, lowland
tropical forests, coastal areas and also near residential areas (Hock and Sasekumar
1979; Wheatley 1989). Consequently, they have broad ecological plasticity to
adapt to different environments. This plasticity is reflected in differences of life
history, reproductive strategy, sizes of groups and feeding ecology (Hadi et al.
2007). Changes of feeding ecology could be seen from the food preference in a
specific habitat.
The species that exist on a specific habitat to survive in abundance is
determined by the density of resources (Macarthur and Levins 1964). M.
fascicularis can take any kind of food available in their home range and adjust
their behavior according to its abundance. This indicates they are omnivorous, but
consume mainly leaves, seeds and fruits (Son 2003, Wheatley 1980, Yeager 1996,
Stewart et al. 2007).
The macaques typically eat in the food patch which is generally feeding
sites or food points. The size of the food patches and patch productivities food can
greatly affect the group size limits either in group monospecific or heterospesific
in various food patch (Perez 1996). The macaques would look for food patches
that have abundant food in the form of an environment that supports the
availability of food.
Those study sites are recreational parks, a high altitude rain forest with a
variety of food sources; natural and artificial food, in which there are some
changes in the environment. In 2012, Nila et al. (2014) reported that the diet longtailed macaques in Telaga Warna was still natural. Nevertheless, the macaques
learned that the visit of tourists is identical with food. The frequency of eating
artificial food was influenced by visitors who come for picnic. The purpose of this
study was to determine a human-induced dietary change of the macaques. By
using the method of Hadi et al. (2007), this study reported that during the last two
years, food preference of the long-tailed macaques in Telaga Warna turned into
artificial food equipped with knowing feeding site preference in a food patch.

MATERIALS AND METHOD
Sample
This research was conducted in Telaga Warna, Sub-district Cisarua,
District of Bogor and Cianjur, West Java Province, Indonesia. The research area is
located at the longitude 10711’05”E to 10720’00”E and latitude 642”23’S to
643”24’S, based on map from Center for Conservation of Natural Resources
(BKSDA), West Java. The study area consists of the Nature Reserve (Cagar
Alam, Bahasa Indonesia) and Nature Recreation Park (Taman Wisata Alam).
Nature Reserve is a natural state that has a specific plants, animals, and
ecosystems or particular ecosystem that needs to be protected and development
occurs naturally. Meanwhile, the Nature Park is a nature conservation area with
the main purpose of tourism and outdoor recreation by Presidential Decree
(Peraturan Pemerintah No. 68 Tahun 1998). Thus, in Telaga Warna there are
developments related to the tourist area. The management of the park has built
five of ten planned bungalow in 2014. Visitors take advantage of the bungalow
terrace to relax and feed the monkeys.
Preliminary study was conducted every weekend on June 7 – 28, 2014 in
order to habituate with the macaques. Data was collected in July until September
2014 from 06:00 am - 05:00 pm. Observation was terminated when the rain
started. Each individual was identified by differentiating their faces, hair colors,
body sizes, shapes of head and body, and scars in their body. There were two
groups of long-tailed macaques that inhabit the study site, troop A (nmax = 49
individuals; 11 adult males, 12 adult females, 2 sub adult males, 5 sub adult
females, 14 juveniles and 5 infants; nmin = 30 individuals; 10 cencuses) and troop
B (nmax = 21 individuals; 2 adult males, 6 adult females, 2 sub adult males, 2 sub
adult females, 6 juveniles and 3 infants; nmin = 17 individuals; 9 censuses). The
observation was focused on troop A.
Method
Daily Activity
Daily activity of the macaques was observed using scanning method
(Altman 1974). The scanning method was used to estimate the proportion of every
categorized behavior that individuals performed in their activities. The categories
of behavior are agonistic, grooming, mating, playing, resting, eating, and moving.
These behavior categorizations were similar with Md-Zain et al. (2010). The
moving activity was divided into individual and group moving. Individual moving
was categorized as moving from each to another source of food in a particular
feeding site, whereas the group moving was categorized as the moving of all
individuals to find another feeding site.
Feeding Site and Food Preference
In foraging, long-tailed macaques look for food patches with abundant
foods, when found then they formed parties after finding the food patches. In
Telaga Warna, the macaques forage in three feeding sites (I, II and III feeding
site) (Figure 1) around the Nature Recreation Park. Feeding site I is located in the

forest near tea plantation where visitors are just passing through so contacts
between macaques with visitors were rare. Feeding site II is located in tourist
visiting area around a lake. Tourists usually come in family or with friends for a
picnic, playing the raft, playing flying fox, or just sitting around the lake. Feeding
site III is located on forest at mountain cliff so humans almost never visit it.

Figure 1. Research location and home range of Troop A long-tailed macaques in
Telaga Warna. Food patch is consisted of feeding sites I, II and III. The
map of home range was taken from GPS Visualizer.
Food items consist of natural and artificially provided foods. Food
available in the home range were defined as natural foods, whereas, foods given
manually by human or left-over of tourist meals or macaques got it in the trash
pots were categorized as artificial foods. Some foods obtained from trash
sometimes cannot be recognized so they were included in uncategorized garbage.
Natural food is obtained from the forest in feeding site I, II and III, whereas
artificial food is obtained only in feeding site II.
Data Analysis
Daily Activity
Daily activity of the macaques was analyzed using software R 3.0.3.
Food Preference
A method to determine food preferences of the long-tailed macaques had
been devised by Hadi et al. (2007). Food preferences were determined by
recording the feeding duration and party size, at every feeding site in a food patch.

4
Feeding duration
(session of an observation period x = 1 to m) on a food
item is the time the first individual consumed part of the food item (i) to the time
when the last individual stopped to feed or leave the feeding site. The feeding
durations (T) of a particular food were accumulated for all sessions of an
observation period (that was, month):

For every session, number of individuals that formed a party in feeding
was used to represent the troop. The
site were varies, hence the maximum size
average party size of each session (Ni) calculated by:

Ni =

M

The proportion of food item i that was consumed by the troop in an
observation period was defined as foraging activity P:

Pi =

x 100%

Part of the plant eaten by macaques was collected and recorded, and then
was made into herbarium. Sample of plants were found then matched with local
names that have been recorded previously. Whereas, the non-identified samples
would be identified further by using Backer and van den Brink (1965) as
reference.

RESULTS AND DISCUSSION
Results
Daily activity
Troop A spent their time mostly on moving 30.7%, eating 30.7% and
resting 24.27%. It is similar with the results of Nila et al. (2014) who did research
in 2012, found that moving was 39 %, eating was 33.5% and then resting 12.2%
respectively (Table 1). But in 2014, showed percentage is much different for
moving individual (26.3%) and moving as a group (4.37%), it indicates macaques

spend more time in the same place. The changes in daily activity, especially the
activity of eating and moving, might be influenced by development of bungalows.
Food preference
Long-tailed macaques in Telaga Warna spent more time at the feeding site
II. In feeding site II, there was interaction between the visitors with the macaques,
so in addition to their natural food, they also get artificial food from visitors. The
situation makes feeding site II have better quality food than feeding site I and III.
Consequently, it affects on food preferences.
In 2012 Nila et al. (2014) reported, natural food (60.1%) was consumed
more than artificial foods (39.9%). While the results of this study showed that
macaques consumed natural food (39.8%) (Table 2A) and consumed a lot of
artificial foods (60.2%) (Table 2B). The change of dietary patterns and the types
of food consumed are associated with the increasing number of visitors (Table 3).

*personal communication
The long-tailed macaques in Telaga Warna spent much time to feed natural
food on stalk of grass (Axonopus compresus) which is only found in feeding site
II. At the time of the fruit season (July-August) the macaques ate a lot of fruits
mainly from sarai (Caryota mitis) and pasang (Lithocarpus sundaicus). They also
consumed part of nangsi (Villebrunea rubescens) that is, flower, young leaf, and
young bark. Some individuals extracted water from the bulb of orchid
(Chelonistele sulphurea) and fiddlehead of fern (Nephrolepis biserrata). Some
individuals also eat animal that is insect.
In addition, the macaques had many artificial foods from visitors and
trashes. Artificial foods from visitors most often given were peanut and banana.
Furthermore, the macaques took directly from the trash and consumed more
uncategorized garbage (7.157%) and noodle (0.367%). During the observation,
there were the constructions of bungalows around the observation area. Carpenter
planed timber and the waste was eaten by juvenile macaques was 0.056%. The
wood used to build the bungalows included the wood from kempas (Koompassia
malaccensis), bengkiray (Shorea spp.), and johar (Senna siamea).

DISSCUSION
The macaques would look for food patches that have abundant food. If all
patches were large and had enough productivity, they could accommodate all
group members (Perez 1996). The change of environment gave effect to diet of
macaques. The construction of bungalows reduced feeding site. Nevertheless,
productivity of food increased due to the increasing number of visitors.
The most widely natural food eaten was stalk of grass which was only
found in feeding site II. It is an effort to get protein from stalk of grass (Nila et al.
2014). At the time of the fruit season (July-August) the macaques ate many fruits
mainly from sarai (Caryota mitis) and pasang (Lithocarpus sundaicus). In general,
long-tailed macaques that live in forest with minimum frequency of contact with
human tend to be frugivorous (Wheatlhey 1980, Yeager 1996). The report from
Yeager (1996), in secondary forest in Kalimantan the macaques were primarily

frugivorous with 66.7% of their food were fruits. The macaques in Telaga Warna
also consumed part of nangsi (Villebrunea rubescens) which was the flower,
young leaf, and young bark. Some macaques also extracted water from the bulb of
orchid (Chelonistele sulphurea) and fiddlehead of fern (Nephrolepis biserrata).
Some individual of the troop of long-tailed macaques were recorded to eat insects.
In the feeding site I, the macaques obtained grasshoppers and larvae of pests tea
from tree leaves and tea plantation. They captured insects stuck to the trunks of
large trees in the feeding sites II and III and grasshoppers in the grass at the
feeding site II.
The long-tailed macaques ate natural foods most widely in July, which
was the month of fasting. The number of visitors slightly decreased and macaques
spent more time in the forest (feeding site III). But when feeding site III showed a
reduction in the preference, they were switched to feeding site I. This possibility
happened during the fruit season cihampelas that only existed in feeding site I,
macaques had a high preference to eat them.
In addition, the macaques received many artificial foods from visitors. The
most given artificial food were peanut and banana, the same foods were reported
in 2012 by Nila et al. (2014). Similar with Telaga Warna, the most frequent
dietary artificial item of macaques in Ciung Wanara West Java (Yudanegara
2006) and Ubud Bali (Wheatley 1989) was peanuts. The visitors could buy the
peanuts easily from vendors near the study sites (Nila et al. 2014). The long-tailed
macaques consumed uncategorized garbage (7.157%) and noodle (0.367%) from
trash. During the observation, there were the constructions of bungalows around
the observation area. Carpenter planed timber and the waste was eaten by juvenile
macaques was 0.056%. The wood used to build the bungalows included the wood
from kempas (Koompassia malaccensis), bengkiray (Shorea spp.), and johar
(Senna siamea).
Artificial food increased significantly in August, when the Idul Fitri public
holidays. Many visitors came from domestic and abroad to have a picnic. This
continued until September, which indicated that long-tailed macaques in Telaga
Warna was still dependent on the visitors. The same thing happened in Ubud Bali,
and Padangtegal Bali (Wheatley 1989; Fuentes et al. 2007). Wheatley (1989)
noted that the provisioning in Ubud increased of number of human provisioned
food due to the increasing visit of tourists in the decade of 1980s; the same case
can also be said to Pangandaran. According to Hadi et al. (2007) in Ubud and
Padangtegal are national tourism that could attract large number of visitors
annually.
Fuentes et al. (2006) reported that macaques that lived in tourism areas in
across Asia and stretching to Gibraltar and Northern Africa have become tourist
attraction. Telaga Warna is one of the tourist areas that can attract domestic and
foreign visitors. The increasing number of visitors each year, make the animal
behavior and diets became habituated. However, conservation efforts were
sometimes still become problems, such as long-tailed macaques in Bali, they are
regarded as an agricultural pest and then hunted in some areas in Bali (Wheatley
1994). Subsequently, the greatest threat from the trade is in the Indochinese
region, especially in Cambodia where 2003-2004 macaques began to be harvested
from the wild, for illegal trafficking to the USA for pharmaceutical testing,
research, development, and for consumption of traditional medicine in China.

10
Regarding the existence of these issues, this time Macaca fascicularis has been
categorized as of “Least Concern” in the IUCN/SSC 2008 Red List of Threatened
Species (Eudey 2008). This matter has become a concern, especially for the tourist
attractions that can attract visitors in large numbers so that it can lead to conflicts
between human with macaques. Thus, awareness needs to be raised for controlling
the management of the tourist area in order to maintain the balance of nature.
Telaga Warna needs strict rules to prohibit feeding of the macaques by visitors. In
this case, however their welfare should depend heavily on nature, thus it is very
important to control the environment in Telaga Warna.

CONCLUSION
Food preferences of long-tailed macaques in Telaga Warna turned into
artificial food because of changes in the environment followed by increasing in
number of visitors.
