IMPROVING THE ECO-TOURISM EXPERIENCE WITH GUIDING SERVICES AND CHSE

Tour guides are other people who most often interact with tourists while travelling in an ecotourism destination. Therefore, the service activities provided by the guide are considered entirely instrumental in shaping the tourist experience. In this Covid-19 pandemic condition, the implementation of the CHSE Health protocol is also considered very important in supporting the creation of a quality tourist experience. This article presents a discussion regarding the influence of CHSE guidance services and protocols on the tourist experience in the Nglanggeran Ancient Volcano Ecotourism Area. The method used is a quantitative inferential method using the Partial Least Square (PLS) approach. The results show that the guidance service has a positive effect on creating the tourist experience. However, the CHSE health protocol implementation has not been proven to affect the tourist experience.


INTRODUCTION
The Nglanggeran Ancient Volcano Ecotourism Area (Kawasan Ekowisata Gunung Api Purba Nglanggeran) is a conservation area whose use-value is enhanced as an ecotourism attraction. Based on the number of tourists, the Nglanggeran Ancient Volcano Ecotourism is designed for small tourism. So it is expected that tourists who visit come in small numbers but have a positive contribution in contributing benefits both economically, naturally, and socioculturally for the local community.
Ecotourism is tourism that sells philosophy, principles and ideals. Ecotourism prioritizes the quality of experience gained by tourists during their activities, interacting with almost all elements in ecotourism destinations (Razak, 2017), so that a quality experience is an essential thing for ecotourism management to create.
The tourist experience has become the focus of tourism marketing experts. Tourists choose a tourist destination driven by value, and the goal itself is a provider of value for tourists. The travel experience offered determines the value. Tourist perceived value is a strategic instrument that can be managed to achieve a competitive advantage for the organization or destination management (Prebensen et al., 2012). The key to gaining an edge in the tourism industry is creating a high-quality travel experience. Creating a high-quality travel experience is creating a unique and memorable travel experience so that it can bring satisfaction to tourists (Dwyer & Kim, 2003;Coudounaris & Stapit, 2017;Kim, 2014).
Every tourist can have a positive or negative experience while travelling. Positive or negative experiences are an unavoidable result of consuming a service product because their needs and desires are different from one another (Yuan & Wu, 2008).
A positive tourism experience results from an impression (Tung & Ritchie, 2011). The impression in question is related to tourist satisfaction and positively influences tourists. At the same time, negative tourism experiences result from disappointment or dissatisfaction and negatively impact tourists (Jung, 2015). Therefore, the dimensions of the tourist experience are positive, and some are negative. The dimension of tourist experience has a broader meaning than satisfying or dissatisfying experiences (Yoon & Uysal, 2005). Because being satisfied or dissatisfied only shows whether tourist expectations are met or not (Crotts & Magnini, 2010).
The attraction of experience is consistent with the shift towards the experience economy. The main goal of tourists is to seek the ultimate experience. So that efforts to meet the inner needs of tourists through the creation of positive experiences become very relevant in the tourism business (Yuan & Wu, 2008).
Research on the tourist experience has often occurred for management and researchers in the hospitality and resort service industry. However, so far, it is still very rare to research tourist experiences, especially in nature-based tourist destinations. In comparison, research related to the tourist experience is fundamental to any tourist destination.
Creating a tourist experience is not just about providing the many features with a tourist product has to offer (Meyer & Schwager, 2007). However, management feels the need to provide the best tourism services, commonly known as excellent service (Hermawan et al., 2018).
Creating a satisfying tourist experience at an ecotourism destination requires a vital role from a tour guide. Tour guides are other people who most often interact with tourists while travelling in an ecotourism destination. Therefore, in addition to the tourist attraction's quality, the guide's service activities are considered entirely instrumental in shaping the tourist experience itself (Anggraeni, 2017). The service of a tour guide also influences the decision of tourists to return to a destination (Purwaningsih, 2013).
The quality of a tour guide is largely determined by his attitude in providing services to tourists. Must-have attitudes include concern for others, pleasant personality, convincing appearance, sense of humour, helpfulness, manners, efficiency, conscientiousness, professional skills, empathy, friendly, patient, trustworthy, and sincere. Another aspect that also influences the tourist experience during a tour is the ability of the guide to provide comments during the trip (Anggola et al., 2020).
In addition to the guiding service factor, the application of health protocols must also be a concern for tourist destination managers in the current state of the Covid-19 pandemic. The results of previous research showed that fears of being exposed to the virus made both ISSN: 2355-6587, e-ISSN: 2528-2220 http://ejournal.bsi.ac.id/ejurnal/index.php/jp 66 domestic and foreign tourists cancel their trips. The application of health protocols is needed to restore tourist confidence in anxiety and the need to travel (Pratiwi et al., 2021;Suprihatin, 2020). In response to the above, the Government of the Republic of Indonesia, through the Kementerian Pariwisata dan Ekonomi Kreatif, has issued guidelines for applying the CHSE health protocol, known as the Clean Hygiene Safety Environment (CHSE). All tourism service managers currently require CHSE to ensure the security and safety of tourists from outbreaks and diseases, especially Covid-19. The application of CHSE that must be applied in tourist destinations includes: providing a place for washing hands, measuring body temperature, maintaining distance, tourists using masks according to the health index, keeping a space, and tourist providers always having disinfectant available (Kementerian Pariwisata dan Ekonomi Kreatif, 2020).
Implementing health protocols can reduce the risk of tourists being exposed to the Covid-19 virus, so tourists are expected to travel in peace. The application of health protocols is thought to have helped shape the quality of the tourist experience in a tourist destination.
Therefore, this article discusses the extent to which service by tour guides and the application of health protocols determine the quality of the travel experience in an ecotourism destination. This study is expected to be a new insight for tourist destination managers to improve the quality of the tourist experience. In particular, through the excellent service approach and the application of the CHSE health protocol.

METHOD Research Location and Time
The research location has been carried out in the Kawasan Ekowisata Gunung Api Purba Nglanggeran, Nglanggeran Village, Patuk District, Gunungkidul Regency, Special Region of Yogyakarta.

RESULTS AND DISCUSSION General description
Nglanggeran is a village administratively located in Patuk District, Gunungkidul Regency, Special Region of Yogyakarta. The area of Nglanggeran Village has an area of 762,0990 hectares which is mainly used for agricultural land, plantations, fields and yards. In There are unique geological phenomena in the Great Hills area, precisely in Nglanggeran Village, Patuk District, Gunungkidul Regency. This geological phenomenon is related to the appearance of old volcanic rocks that formed about 20 million ago (late Early Miocene). The volcanic activity that occurred at that time produced volcanic rock ruins in volcanic breccias, agglomerates, tuffs, and pillow lava. The area is called the Nglanggeran Ancient Volcano, which is located in the Batur Agung Hills area in the northern part of Gunungkidul Regency with an altitude between 200-700 meters above sea level. The Nglanggeran Ancient Volcano area is located in the southern zone of Central Java-East Java. This area is an area whose mythology is composed of old volcanic material, and the landscape has extraordinary beauty and is geologically unique and has high scientific value (About Nglanggeran Tourism Village, 2021).
Karang Taruna groups initiated the Nglanggeran Ancient Volcano area in 1999 with the awareness of caring for the environment and the community planting trees in an arid mountain area between boulders of skyscrapers. That year was the beginning of the village youth group making Nglanggeran Village a tourist destination by only charging an entrance ticket of IDR 500 per person. Karang Taruna groups are starting to realize their tourism potential with the increasing number of visits. So in 2008, the Badan Pengelola Desa Wisata Nglanggeran took over its management by adding various facilities to support natural wealth in the form of hills with unique characteristics. They can be adequately explored to provide benefits to the surrounding community.
In addition to the potential in the form of ancient volcanoes, the Nglanggeran area also has rare flora and fauna. Rare flora found in this ecosystem includes tremas plants, which are medicinal plants that only grow in ancient volcanic ecosystems. In addition, there are also various other plants, such as the rare white of ficus, kepoh, gayam, bibisan, noni, sugar palm, pule ireng, cemberit, and several other plants. For fauna, the Nglanggeran Ancient Volcano area is also a habitat for tigers, long-tailed monkeys, snakes, kepodang bird, Javan eagles, starlings, owls, and several other animals.
Geomorphologically according to the top of the Nglanggeran Ancient Volcano, it consists of several interesting natural phenomena as many as five mountain peaks, namely Mount Kelir, Gedhe, Bongos, Blencong, and Buchu. This area has various myths of local beliefs and a solid relationship with local wisdom so that several mountains are named after Javanese terms with various folklores behind them. Each peak in the Nglanggeran Ancient Volcano Ecotourism Area has a shape and high historical value, including the following:

Mount Kelir
This mountain has a shape like a kelir. In Javanese terms, kelir means a white cloth that is often used as a screen in wayang shows. The community believes Mount Kelir to be the residence of the mythological figures Ongko Wijoyo and Punakawan (Hermawan et al., 2019).

Mount Gedhe
Mount Gedhe is the largest mountain in the Nglanggeran Ecotourism Area. Mount Gedhe has the highest peak suitable for viewing the surrounding natural scenery. Usually, climbers use this place as a place to rest and camp.

Mount Bongos
Bongos come from the Javanese language, which means charred black charcoal. As the name implies, the colour of the rock from this mountain is very black, like charred charcoal. Mount Bongos is very suitable for tourists with an adventurous spirit because it has a steep and steep climbing path, thus providing new challenges and exciting experiences.

Mount Blencong
Mount Blencong comes from the word Blencong. Blencong is a Javanese term that means lighting in a puppet show.

Mount Buchu
Based on the community's belief, Mount Buchu is said to have originated from the peak of Mount Merapi, which Punokawan moved to fulfil the number of mountains on Mount Seribu. The shape of Mount Buchu is high and pointed, so it is suitable for rock climbing by nature-lovers.

Comberan Water Source
This area is a spring that has never experienced drought at the peak of Mount Nglanggeran. Comberan comes from the Javanese language, which means the sewer of the former bathroom waste. The community believes this area is a bathing place for angels. With this story, the Comberan Water Source is believed to ISSN: 2355-6587, e-ISSN: 2528-2220 http://ejournal.bsi.ac.id/ejurnal/index.php/jp 70 make you stay young if it is used to wash your face. The Comberan Water Source has a hermitage for the "Prehatin" ritual. Usually, tourists come on certain days to perform rituals.

Mardhido Tlogo
Tlogo Mardhido is a bathing place for a horse Sembrani riding on an angel. Tlogo Mardhido became a sacred place by the local community and was used as a meditation. It is said that there are traces of Sembrani's horse treads on the rocks.

Nglanggeran
Ancient Volcano is fascinating because it is composed of giant andesite boulders that present gorgeous natural scenery. This mountain has two highest peaks, namely the western and eastern peaks.
The beautiful natural scenery spoils the eyes of mountain climbers-a wide-spread rural atmosphere with terraced rice fields around. Adventure-loving tourists can try climbing the boulders because this location is perfect for rock climbing, trekking, cruising and camping. The Nglanggeran Ancient Volcano Ecotourism Area is relatively easy to find by tourists. Nglanggeran Ancient Volcano Ecotourism Area is about 25 km from the city centre with a travel time of about 45 minutes using a private vehicle. Access to the location is good with complete directions, so it can help tourists to find the place easily.

Characteristics of Research Data
Based on the research data, it can explain the respondents' characteristics. Characteristics of respondents based on age are as follows: Based on table 2, it can be seen that Nglanggeran Ancient Volcano tourists have a reasonably balanced tourism segment when viewed based on regional origin. Both tourists from Yogyakarta and those from outside the Yogyakarta area are almost the same.
These conditions indicate that the Nglanggeran Ancient Volcano Ecotourism Area is attractive to tourists from various regions. The uniqueness of the Ancient Volcano as a geological formation and its history as an ancient volcano is hard to find in other areas. The beautiful natural scenery is also the main attraction factor because it can present a different atmosphere from the tourist environment.

Descriptive Analysis Results
Service Variables (X1) in the Nglanggeran Ancient Volcano Ecotourism Area can be known by dividing the total number of answers to the questionnaire by the total number of questions multiplied by the number of respondents. Then the calculation results are compared with the scale on the Likert scale: 5 (very good), 4 (good), 3 (neutral), 2 (poor), 1 (very poor). The results of the formula can be written as follows: ∑ Questionnaire Answer = Average Score ∑ Question items X Respondent

Descriptive Analysis of Tour Guide Service Variable (X1)
Based on the calculation formula above, it can be concluded that the respondent's perceived value of the Tour Guide Service Variable (X1) is as follows: 1204 = 4,09 6 X 49 Based on the results of the calculation above, it is known that the value of respondents' perceptions of the Tour Guide Service Variable (X1) is 4.09. After being consulted with the weight on the Likert scale of the study, it can be concluded that respondents tend to give a good assessment of scouting services in the Nglanggeran Ancient Volcano Ecotourism Area.
Meanwhile, if you look at the average value of each indicator on the variable, it has the following values: The description of respondents' perceptions of the Travel Experience Variable (Y) in the Nglanggeran Ancient Volcano Ecotourism Area can be identified by descriptive analysis in the same way as the last variable.
Based on statistical calculations, the respondent's perceived value of the Scout Service Variable (X1) can be generated as follows:

1308
=3,8 7 X 49 Based on the results of the above calculations, it can be seen that the respondent's perceived value of 3.8 is rounded up to 4. After being consulted with the value of the Likert scale of the study, it can be concluded that respondents tend to give a good assessment of the quality of the experience obtained.
Meanwhile, if you look at the average value of each indicator on the variable, it has the following values: Based on the results of the analysis in table 5 above, it can be concluded that almost the entire value of the travel experience indicator has a value of 4 which means good. In the sense that the Nglanggeran Ancient Volcano Ecotourism Area has a value that can provide a quality experience for tourists, namely an experience that is memorable, fun, healthy and adds religious value for tourists.

Inferential Analysis Results
A quality experience is essential to creating ecotourism management because ecotourism prioritizes the quality of experience gained by tourists during their activities in destinations (Razak, 2017). Ecotourism management involves the interest of tourists to be willing to do activities full of dedication and willingness to enjoy outdoor activities. The nature of the Ecotourism Area of Mount Apri Purba Nglanggeran is a very challenging attraction for tourists to explore. Tourist guides are thought to create a quality tourist experience in these nature-based destinations.
In addition, the Covid-19 pandemic has made quite a change in terms of tourist travel patterns. At this time, tourists tend to ISSN: 2355-6587, e-ISSN: 2528-2220 http://ejournal.bsi.ac.id/ejurnal/index.php/jp 74 look for safe tourist attractions. Apart from being safe from the dangers of the physical environment (Hermawan, 2017), being safe at this time can also mean that managers have tried to implement the Covid-19 Health protocol (Pratiwi et al., 2021;Suprihatin, 2020). The Covid-19 Health Protocol in the tourism sector in Indonesia is known as the CHSE protocol, which means Cleanliness, Health, Safety, Environmental Sustainable (Tarunajaya et al., 2020). The application of CHSE in the Nglanggeran Ancient Volcano Ecotourism Area needs to be considered to meet the shifting preferences of tourists in travelling at this time.
The influence of guide services and the application of the CHSE Health protocol on the tourist experience in the Nglanggeran Ancient Volcano Area has been carried out with the following results:

Guide Services (X1) Influence on Travel Experience (Y)
In addition to natural factors, the progress of ecotourism destinations must be supported by exemplary service by tourism managers. The performance of tour guide services in the Nglanggeran Ancient Volcano Ecotourism Area is considered quite good by tourists according to table 3 with the assessment of each of the indicators above.
The concept of excellent service is still considered a solution in tourism services that can meet the needs and desires of tourists in general. One of the essential figures in providing tourist services in ecotourism destinations is a tour guide because the tour guide is the person who most often interacts with tourists while carrying out nature cruising activities.
Based on the T-test results in table 10, it is proven that the guiding service has a significant effect on the travel experience. This effect is evidenced by the P-value of 0.000, more diminutive than 0.05. This result is in line with previous research that states that scouting services positively affect the travel experience (Anggraeni, 2017).
The original sample value of 0.658 means that the guiding service has a positive effect on improving the quality of the tourist experience. So that the higher the quality of the scouting service, the higher the satisfaction obtained by tourists.
Creating a high-quality travel experience creates a unique and memorable travel experience to satisfy tourists (Dwyer & Kim, 2003;Coudounaris & Stapit, 201 Kim, 2014). Positive experiences are very relevant in the tourism business (Yuan & Wu, 2008). Evaluation on descriptive analysis indicated that several things caused the quality of scouting services in Nglanggeran Ancient Volcano Ecotourism. Tour guides at Nglanggeran Ancient Volcano already have good skills in guiding (table 3). A positive assessment of this skill aspect can occur because the guides at Nglanggeran Ancient Volcano Ecotourism already have a very long experience in scouting.
The readiness of tour guides has been rated as good by tourists ( Based on the descriptive analysis, it can be seen that the average tourist feels safe when travelling when accompanied by a tour guide at Nglanggeran Ancient Volcano Ecotourism (table 3). Feelings of security when travelling in the open are essential to be fulfilled by ecotourism service providers, especially scouting services. Tourists feel safe when travelling in nature accompanied by a professional tour guide. Experienced guides know the conditions of the destinations visited and have reliable skills in conducting scouting services.
The following common criterion inservice assessment is the hospitality aspect (Hermawan et al., 2018). Tour guides in the Nglanggeran Ancient Volcano Ecotourism Area are considered friendly by the average tourist (table 3). The friendliness of the principles when carrying out scouting activities is an essential factor so that tourists feel welcome. In addition, the guide's skill in making jokes can also liven up the atmosphere.
Politeness is also an aspect of assessment in tourist guide services, for example, the ability of guides to treat tourists well during their tour. The tour guide at Nglanggeran Ancient Volcano Ecotourism always refrains from discussing sensitive issues such as ethnicity, belief, race, politics, and others (table 3).
The last thing that is no less important in the service assessment criteria is responsiveness. Tour guides are considered quite responsive in serving and adjusting the needs and desires of tourists while travelling in the Nglanggeran Ancient Volcano Ecotourism Area (Table 3).
The role of guides is vital in ecotourism destinations to provide more indepth information for tourists. The guide plays a role in explaining the details of every tourist attraction in the tourist destination so that tourists do not just come to see nature but also learn the storytelling of each object, activity or interest.
Ecotourism guides play an essential role in realizing experiential learning in nature.

CHSE Protocol (X2) Does Not Affect Travel Experience (Y)
Previous research stated that the application of health protocols is related to tourist trust amid anxiety conditions and the need to travel during the Covid-19 pandemic (Pratiwi et al., 2021;Suprihatin, 2020). Even the implementation of the CHSE (Cleanliness, Health, Safety, Environment) adaptation program also affects the satisfaction of destination visitors (Arlinda, 2021).
However, based on the T-test results (Table 10), it is proven that the CHSE protocol in the Nglanggeran Ancient Volcano Ecotourism Area does not affect the travel experience because the P-Value of 0.099 is more significant than 0.05. This result is certainly not in line with the positive findings of previous research as mentioned above. For example, research from Pratiwi et al. (2021) and Suprihatin (2020) mentions that health protocols are needed to restore tourist confidence in anxiety and the need to travel.
There has not been much previous research explaining exactly how the CHSE protocol does not affect the travel experience. However, speculatively, this might happen considering that the character of the Ancient Volcano tourist destination is an ecotourism destination that provides tourists with opportunities for activities in an open environment. So tourists may not feel the application of CHSE, such as the command to keep a distance. Checking the body temperature of tourists is also only carried out once at the entrance ticket; this is also suspected to be not very relevant in shaping the overall tourist experience.
Although it does not influence creating a quality tourist experience, the implementation of health protocols in the Nglanggeran Ancient Volcano Ecotourism Area is still mandatory to ensure the health and safety of tourists while travelling. Implementation of health protocols is one of the principles to minimize the risk of disease hazards (Hermawan, 2017).
ISSN: 2355-6587, e-ISSN: 2528-2220 http://ejournal.bsi.ac.id/ejurnal/index.php/jp 76 The implementation of health protocols is still needed to break the Covid-19 chain. Currently, every tourist destination must implement the CHSE Health protocol, including natural tourism destinations such as the Nglanggeran Ancient Volcano Ecotourism. The application of CHSE is also one of the requirements for permits to open tourist destinations in the New Normal era. Efforts to prevent hazard risks are generally not significant enough for tourists to pay attention to at a safe time, so they do not contribute significantly to the travel experience. However, one day, risk prevention efforts will usually be questioned if a disaster occurs.   Figure 3 above, it can be explained that the influence of Guide Service and CHSE health protocol simultaneously has an effect of 0.422 or 42% on tourist experience. Then partially guide service has a positive effect of 0.680, so the higher the guide service, the tourist satisfaction will increase by 0.680. While the CHSE Health Protocol implementation is -0.412, this value is not significant when referring to the T-Test Results in table 6. This picture is an explanation of the previous discussion

CONCLUSION
Tour guides are other people who most often interact with tourists while travelling in an ecotourism destination. Therefore, the service activities provided by the guide are considered entirely instrumental in shaping the tourist experience. In this Covid-19 pandemic condition, the implementation of the CHSE Health protocol is also considered very important in supporting the creation of a quality tourist experience.
Guiding services in the Nglanggeran Ancient Volcano Ecotourism Area are
