The Potential of Butterflies in Tourism Diversification Product: Case Study at Coban Rais Waterfall, Batu, East Java

The diversity of Butterfly in Coban Rais is one of the potential resources for tourism product diversification and development. The aims of this paper are to determine the magnitude of the butterfly potential as a form of tourism products diversification and development in a sustainable tourism industry. There are 107 species of butterfly that come from six families was found in Coban Rais waterfall. Some species have a very large population in a specified activity, such as mud-puddling and mating. Udara akasa has the highest potential to make colony and Cyrestis lutea is a species that have the potential as a major attraction in the mud-puddling activity. Sector 3, the location of riparian with sand and gravel, is the site of the largest butterfly visits. The dry season is the highlight of a butterfly visit in Coban Rais. Development of human resources is important for the tourism products diversification in Coban Rais, i.e. the butterflies observer and visitors services. We recommend establishing a breeding center for butterfly population recovery and educational goals for visitors.


INTRODUCTION 
Tourism product has evolved rapidly followed by the rise of profits until early of this decade [1].The high demand of tourism site reflects the economic development which transform rural areas into cities and urban settlements [2].However, this development is not well-matched by adequate recreation facilities and people has large of interest on varying destination.This is an opportunity for tourism organizer who immediately undertake massive investments to build and develop attractions, both natural and artificial.Thus many managers, agents, and absorption of labor in the tourism industry lead to a tighter competition [3].
However, in the end, innovation and product diversification will determine the sustainability of a tourism destination.Novelty is mostly sought after by tourists, and many of them would not go again to a place that has been visited [4].This condition is due to the form of management and development which are not considered by stakeholders.Instead of doing development, many tourism destinations were closed due to no longer visited by tourists, and left the natural  Correspondence address: Agung Sih Kurnianto Email : agung.sih.kurnianto@gmail.comAddress : University of Brawijaya, Jl.Veteran Malang, Malang 65145.
Ecotourism is nature-based tourism concept which has three main pillars: profits, culture, and recreation [6].All three became one to build a sustainable tourism and benefit to nature and society.However, ecotourism also have the same challenges and must be faced.Innovation and development is the key to maintain the tourism destination existence through diversification tourism products [7].
Coban Rais is a tourism destination with 70 m in height waterfall as a main object.It is located in the southwest of Batu: Oro-oro Ombo village, Batu City (Fig. 1), East Java, Indonesia, with an altitude of 1002 meters asl [8].This location is in the management of PT Perhutani (Persero).Coban Rais is well known by student community and visitors with their fascination in waterfalls.In fact, visitors get to know Coban Rais as a secondary objective on their visit in Batu City [8].Most of the people do not know any other Coban Rais potential as many species of butterfly habitat.The purpose of this paper is to determine the magnitude of the butterfly potential as a form of diversification on tourism products and plans the future development in sustainable tourism industry.

MATERIAL AND METHODS
This research was conducted in three period of observations: dry season (July), monsoons (August-early September), and rainy season (October) 2015.However, every season does not trigger a change in the community structure and their migration.Observations were made only on the type of butterfly that flew during the day (diurnal).Identification used field observation approach.The line between the gatehouses to the waterfall is divided into five main sectors; each sector is 500 m long (Fig. 2).First sector was cover a parking lots, camp ground, and ticket window, and the last sector was cover waterfall position.Each sector was observed specifically and butterflies as the object identified and documented to support the identification.Several species which requires detail identification on the upper side were catched and their pattern carefully documented.The results of three time observations will be compiled in the form of observation list.Each location visited by more than 20 individual butterflies was recorded as attractive location [9].This location indicates that there is temporal abundance (butterfly in colonies) due to mud-puddling or mating behavior.Each location visisted by rare species and rarely were marked as significant locations.
This location could be predicted as habitat of food plant for rare butterflies and require special analysis and attention.Attractive and significant locations were marked in GPS (Global Positioning System) to establish a geographic analysis of data as a support of tourism maps.The equipments that used for documenting is 1100 D Canon DSLR camera with kit and a 75-300 mm USM lens.An insect net with 50 cm diameter is used to catch butterflies.The results of the observations are recorded as a table form in the field note.Study of literature-based data is done by compiling butterfly-watchers record, either species or families completeness and location.

RESULT AND DISCUSSION
We discovered 107 species (Appendix 1) that come from six families.Some species have a very large population in a specified activity, such as mud-puddling and mating.We recorded several species that are always found in colonies and solitary.However, some species have the ability to form a large colony than others (Fig. 3), such as Udara akasa Horsfield (Fig. 4).Colony forming process carried out when butterflies do the absorption of minerals together [10].This activity is more known as mud-puddling.Butterflies absorb minerals such as potassium and sodium which derived from animals and humans sweats, feces, organic waste, or urine [10].Some minerals dissolved by water and deposited on the wet sand and evaporated, thus attracting butterflies to come and do a mud-puddling activity.We also found a rare species Troides cuneifera Oberthür (Fig. 5) that protected by Indonesian republic government through the UU no.5/1990 [11].This rare species was found in sector 3, when its fly through the tourist track.The observation shows that sector 3 is the most preferred route of butterflies visit, with an average value of 1.75 on three observations time, then followed by sector 1 and sector 4 (Fig. 6).The highest average visit of butterfly in Coban Rais is during the dry season, when many butterflies observed around water flow.During the rainy season which is in the second position, a lot of butterflies seen among the flowers which available along the sector (Fig. 7).Coban Rais equipped with water flows which are always there every year.The altitude of 1002 meters makes it into a potential diversity of highlands species that may not exist in other locations.This altitude makes surrounding area of Coban Rais is cool.Besides of the waterfall, the scenery along the route is very interesting (Fig. 8).Visitors can enjoy Batu city scenery from Panderman mountain foothills.Today, many tourist utilize the available facilities, such as camping grounds and jungle trekking route.Butterflies that found in sector 3 is much higher than in others, even compared to sectors 5 which includes the location of the waterfall.The waterfall is very humid and windy due to the heavy movement of water (Fig. 9), so the less favored by butterflies when they still requires sunlight.Sector 3 is a route that through the stream banks of Coban Rais River.Riparian is often contains of water-borne minerals from organic matter, such as humus, feces, or urine of animals.These deposits evaporate and invite many butterflies to come and do mud-puddling [10].This activity is supported by conditions in sector 3 that has a small plateau and composed by fine sand, gravel and surrounded by a lot of shrubs are available for butterflies as well as a sunbath perch.
Mud-puddling is dominated by Udara akasa (family Lycaneidae).Udara akasa is potential as an interesting object of attraction, because it can be minority part of a colony or dominance in a colony.However, because of the size is very small (1 cm in length), a deep identification is required by arrest or documentation.Udara akasa is not sensitive in human traffic and will soon return to mud-puddling location when disturbed, so make it as interesting side of their attraction.This will make the visitors looks like walk among hundreds of butterflies in that route.Cyrestis lutea is a butterfly of the Nymphalidae family and became the interesting objects of observations on the mud-puddling activity.In addition to the high ability to form colonies of mud-puddling, this species has a yellow-gold glittered as the sun reflected off.That size is also quite large, so it is very representative when used as an observation object.This is different to Eurema blanda (Pieridae family).This butterfly is in yellow colour that looks very monotonous.It is presence in each colony as minority in a small number.
Sectors 1 and 4 being the location which is pretty much visited by butterflies, supported by large flowering plants found in these locations.Butterflies much need nectar for food.Some butterflies are known to absorb organic material on this site is derived from the sap, rotting fruit, and the fluid that comes out of the shoot.These products contain a lot of sugars that needed by butterflies, especially females [11].
Sector 2 is the route of the least visited by butterflies.Vegetation that seen in sector 2 is short grasses between the pines.The possible reason of the least visit of the butterflies due to plants that are not diverse, thus reducing the potential for the existence of the food chain cycle [12], where the butterfly is included.Observations show that the butterflies were seen in sector 2 just flew through without a perch or any other activities.
Comparison of butterflies in the seasons showed a high butterfly visit during the dry Butterflies Ecotourism Product in Coban Rais (Kurnianto et al.) season.The scorching sun will make water in soil surfaces and plants evaporated.These conditions favor the evaporation of mineral which contained at top soil, thus supporting the many activities of mud-puddling [13].In addition, the condition of Coban Rais which always have water is support the activity of mud-puddling, such as mineral dissolution and survival of flower plants.
The lack of rain in time of drought also increases the success of metamorphosis in Lepidoptera, including butterflies [13].Rainwater will break the cocoon as a part of the metamorphosis.
Rainy season is quite exciting visit a butterfly on a location.Very high rainfall can trigger the growth of flowers and attract butterflies as nectar eaters [14].Transitional season did not attract butterflies; possibly due to seasonal changes occur often quite extreme.This condition occurs where the rain and heat come in often erratic [15], so that the process of metamorphosis and reproduction of butterflies are often disrupted.
Coban Rais which has the potential of beautiful natural scenery, gifted by a diversity of butterflies that have the potential as a tourism attraction.The emergence of butterflies' colonies on routes strongly supports the ease of visitors to enjoy the butterfly as an object.Visitors can photpgraph the butterflies on the location and the right time.Butterflies in Coban Rais generally can be enjoyed throughout the year, but the knowledge of the right season can help visitors in assessing the condition of the butterflies diversity and time of their visit.
The tourism products such as butterfly or any other wildlife component is a great potential for destination development.In contrast to tourism, major attractions such as scenery or artificial activity, observation of wildlife is not boring and always growing up.Some types of wildlife also have a certain visitors with a selection of tourism concept.This concept applies to the selection and the prices were very strict quotas.Nonetheless, it is still has a visitors enthusiasts [1].
However, in addition to the benefits, the wildlife based tourism has challenges in its development as sustainable industry.The main challenge is to continue the research which provides information that will be used as attractions for visitors.This is related to the appropriate time and location of visits.The strength of wildlife information that intended as an attraction is the main factor in attractions competition or even tourism with the same object.
Research is also crucial to the development of attractions and discovers the limits of carrying capacity [16], in this case is to support the protection of wildlife which became the main object.The condition of the object in the living form is very important to conserved and managed properly, especially developed in: population, the intensity of visits, and the condition of wildlife [1].
Coban Rais in the development of the butterfly as a tourism product requires a few things, especially adequate human resources [17].The existence of the officer who is specifically understood all wildlife behavior that is used as an object of attraction is very important, especially in the field of behavioral and ecological things.The existence of the officer who is specifically observing the behavior and ecology of the location is very important and contribute any useful information for visitors, after being processed by manager or leader of tourism destination.
Officers within the tourism site needs to develop their ability to serve visitors.Coban Rais is in need officers who served the ticket seller and guiding services in walking through the routes to the waterfall.
Resources in the facilities and infrastructure forms are need to be developed, especially routes that intended specifically as a tourism.Coban Rais has a main route that must be maintained of the carrying capacity for the sustainable butterfly attraction.The cutting of the grass beside of the route should only be done in the rainy season and not done on sector 3 that have a lot of butterflies, to prevent of damaging the food plant or kill the butterfly larvae.It is not recommended to control weeds or wild plants by using chemicals because it will kill all insects, including butterflies.
The attraction infrastucture that support tourism activity has generally been available in Coban Rais, such as parking lots, a ticket window, information boards, directions, bathroom, musholla, camping ground, etc.However, in the development of butterfly as a tourism product, it is advisable to establish a semi-natural breeding center of butterfly.The butterfly observer can breed some species, either rare or not, with the purpose of recovery of butterfly population.In addition, breeding butterflies can be useful to support the benefits of education for visitors such knowledge on the butterflies conservation, Coban Rais as a nature tourism is very vulnerable to the destruction, such as landslides (Fig. 10), flood, or the collapse of the trees that cover the route.The indispensable treatment of area that will minimize obstruction of route conditions due to damage.The emergency conditions also require immediate repairs and is possible only when managers have officers that ready in restoring routes or other tourist facilities in general.

CONCLUSION
The butterflies in Coban Rais was diverse and potentially able to developed as natural attarction.The butterfly development as a tourist attraction in Coban Rais must be supported by human resources, especially knowledge of the field and the ecologicalof butterflies, as well as improve services to visitors.Additional facilities are advised to be built is breeding center as supporting education for visitors and population recovery.
