3.1. Research Framework and Hypotheses
In this study, several hypotheses are measured based on the research model, as seen in
Figure 2. The analysis used is multivariate structural equation modeling with twelve path coefficients.
Perceived behavioral control is one of the three concepts expressed by Ajzen in the Theory of Planned Behavior (TPB) [
24]. Many studies have investigated perceived behavioral control and its effect on individual behavioral intentions, such as behavioral intentions to recycle, customers’ intentions to choose environmentally friendly restaurants, and ecotourism behavioral intentions [
25,
26,
27,
28]. Perceived behavioral control is an individual’s perception of the ease or difficulty of performing a behavior. The more individuals perceive many supporting factors and fewer inhibiting factors influencing the performance of a behavior, the more the individuals will tend to perceive the ease of performing the behavior. Conversely, the more individuals perceive fewer supporting factors and more inhibiting factors influencing the performance of a behavior, the more the individuals will tend to perceive difficulties in performing the behavior. When a person feels that an activity is easy to perform or that there is only a bit of a barrier, they will perceive the activity as easy to perform and will be more likely to perform it. [
29,
30].
The relationship between perceived behavioral control and behavioral intention in the context of tourism in general and ecotourism in particular has been found previously. Seow et al. found a positive relationship between perceived behavioral control and behavioral intention in the case of medical tourism in Malaysia [
30]. A positive relationship between perceived behavioral control and the behavioral intention was also found in the context of ecotourism by Tsung and Jan [
7], where there is a positive and significant relationship between perceived behavioral control and ecotourism behavioral intention in the case of nature-based tourism sites in Taiwan. Therefore, the first hypothesis in this study is:
H1. A person’s perceived behavioral control positively affects his or her ecotourism behavioral intention.
Subjective norm refers to the influence of social pressure that encourages or prevents individuals from taking specific actions [
31]. Social pressure can come from the surrounding environment, such as parents, relatives, or close friends. Ajzen explains that when family or friends have a positive attitude toward specific actions (subjective norm), a person’s intention to take that action (behavioral intention) will increase to meet their expectations [
24]. A positive and significant relationship between subjective norms and behavioral intention in the context of general tourism was found previously. Previous studies found a positive relationship between subjective norms and behavioral intention in case studies in Australia, in heritage tourism in England, and in China’s Huangshan National Park [
32,
33,
34]. These studies align with the research of Lee and Jan [
7], which revealed that subjective norms have a positive and significant effect on behavioral intention in the context of ecotourism. Therefore, referring to research related to tourism in general as well as research on ecotourism in particular, this study formulates a compatible hypothesis, namely:
H2. A person’s subjective norms have a positive effect on his or her ecotourism behavioral intentions.
Over time, the need to understand the attitude and behavior of tourists regarding the environment began to attract the attention of researchers [
35]. Ajzen explains attitude as a person’s tendency to respond favorably or unfavorably to objects, people, institutions, or events [
24]. In tourism, especially ecotourism, environmental attitude is one aspect that receives more attention [
36]. According to Han et al. [
22], an environmental attitude refers to a person’s attitude toward an object or environment. Amyx et al. [
37] define environmental attitude as an attitude oriented toward caring for the environment. Someone with a high environmental attitude can be interpreted as someone who cares about nature and the environment.
Regarding traveling, people with an awareness of the importance of preserving the environment tend to choose ecotourism over other types of tourism because ecotourism provides sustainable facilities by eliminating the negative impact of tourism on the environment [
8]. Investigating the environmental attitudes of tourists can provide insight into the estimated market demand for tourism products and services and can generate policy implications to reduce the negative impacts on tourist destinations’ environment. Environmental attitudes can also influence the preferences and motives of tourists to use services and choose tourism destinations [
38] The positive influence of environmental attitude occurs because the more a person likes an environmentally based tourism destination, the higher his intention to visit the site [
39].
In previous studies, the relationship between environmental attitudes and environmental behavior was investigated. Environmental behavior itself is related to several variables, such as the intention of tourists to pick up trash in protected areas [
40], behavioral ecotourism intention in forest recreation areas [
28], and the intention of the environmental behavior of tourists in ecotourism resorts [
41]. The findings above show that environmental attitude positively affects various environmental and behavioral factors, mainly behavioral intentions, in the context of ecotourism. Other studies also support this relationship, as shown by research from Lee and Jan [
7], which investigated the influencing factors of behavioral intention. It was also found that ecotourism behavioral intention was positively influenced by environmental attitude. Therefore, the following hypothesis is proposed:
H3. A person’s environmental attitude has a positive and significant effect on his or her behavioral ecotourism intention.
Christensen et al. [
42] revealed that self-identity serves to distinguish oneself from other individuals and is used to conform to the values, beliefs, and social behavior in which a person is located. Bernstein and Solomon [
43] define self-identity as an individual’s assessment of the image of himself as someone who is unique and distinguishes himself from others. If the individual feels that he already has an identity, then he will be aware of the characteristics of his personality and tend to be able to regulate the orientation of his life. For example, people who see themselves as recyclers are usually more likely to recycle than those who do not see themselves as recyclers [
44]. In the world of tourism, especially ecotourism, one aspect of self-identity that receives more attention is self-identity ecotourism. In contrast to self-identity in general, ecotourism self-identity, developed by Lee and Jan [
7], refers to an individual’s understanding of himself as a tourist who tends to engage in ecotourism behavior. The higher a person understands himself as a tourist who tends to be involved in ecotourism, the higher the chances of him being involved in ecotourism behavior.
Previous research has used the latent variables of environmental self-identity, green identity, a sense of community, and religiosity to predict proenvironmental behavior [
45,
46,
47]. The results showed that the identity variable positively affected proenvironmental behavior. Furthermore, self-identity was developed by Lee and Jan [
7] to investigate its effect on ecotourism objects. The study revealed a positive and significant influence between ecotourism self-identity and subjective norms. Therefore, this study formulates a consistent hypothesis, namely:
H4. A person’s ecotourism self-identity has a positive effect on his or her subjective norms.
Several studies have shown that value relates to environmental attitude [
48,
49,
50]. Value-Based Theory [
51] provides an excellent theoretical framework to explain how environmental values influence attitudes. The Value-Based Theory framework explains that environmental attitude results from individual value orientations. Three value orientations govern this environmental attitude: (a) biosphere value orientation (that is, attention to values that are closely related to the natural environment and biosphere), (b) social altruistic value orientation (i.e., concern for the welfare of other human beings), and (c) egoism or self-interest (i.e., concern for one’s welfare). Of these three environmental attitude value orientations, other studies have further supported that biosphere value is the best antecedent variable to predict environmental attitude [
48,
49,
52]. Individuals who hold values related to the natural environment and biosphere tend to have a positive attitude toward environmental protection efforts.
Previous studies have investigated the influence between subjective norm and environmental attitude in the context of ecotourism. The study revealed that biosphere value positively and significantly influences environmental attitudes [
7]. From the description above, the sixth hypothesis was formulated in this study:
H5. A person’s biosphere value has a positive effect on his or her environmental attitude.
Perceived usefulness (PU) was first popularized by Davis [
53] in the Technology Acceptance Model (TAM). PU is defined as a person’s perception of how an action can provide benefits. The TAM model is adopted from the TRA model, where a person’s reaction and perception of something will determine his or her attitude and behavior.
In the context of tourism in general, Lee et al. [
54] used the Technology Acceptance Model (TAM) to examine the influence of Facebook in encouraging users to attend a festival. They examined how Facebook users’ perceptions of perceived usefulness, ease of use, and enjoyment affected their intentions to participate in festivals. In contrast to tourism in general, ecotourism exists as an alternative form of tourism, provides tourists with learning experiences, and offers much knowledge related to the environment and environmental conservation strategies for tourists. When someone does an ecotourism activity but does not feel any positive benefits, they may have low perceived ecotourism usefulness. Individuals with low perceived ecotourism usefulness will also tend to have a low environmental attitude. The insight is in line with how the positive influence of perceived usefulness was found on attitude, where the more that people feel that the actions taken provided many benefits, the higher their intention is to do so. The previous research by Lee and Jan [
7] in the context of ecotourism also found a positive relationship between perceived ecotourism usefulness and ecotourism behavioral intention. From the description above, as well as empirical evidence from previous research, the proposed hypothesis was made:
H6. Perceived ecotourism usefulness has a positive effect on a person’s environmental attitude.
A person’s knowledge of an issue can significantly impact decision making [
55]. Laroche et al. [
56] revealed that knowledge is an aspect that influences consumers to collect and organize information that influences decision making and how consumers will evaluate a product or service. Environmental knowledge is also defined as one’s understanding of environmental influences, environmental values, and impacts that have the potential to damage the environment [
57]. The more someone has a higher level of environmental knowledge, the more it affects a person’s intention to use a product or service related to the environment; this happens because more knowledgeable people will be able to form stronger opinions and stances. The situation also applies to the context of ecotourism, where someone with a higher level of knowledge about ecotourism sites will influence their intention to carry out ecotourism activities.
Previous research was conducted by Fang et al. [
22] to investigate the effect of environmental knowledge on behavioral intention. The research was conducted to develop environmental awareness through interaction between humans and the environment so that people are more aware and understand environmental problems. Thus, the following hypothesis was formulated:
H7. A person’s environmental knowledge positively affects his or her ecotourism behavioral intentions.
Environmental concern is described as a person’s level of awareness of problems related to the environment [
58]. Schultz et al. [
59] define environmental concern as a caring feeling that arises from environmental problems. Environmental issues increasingly being discussed in both print and electronic media include waste, the biosphere, responsibility for the environment, education, health, and the scarcity of energy sources, making consumers care about environmental issues. Environmental concern is a proenvironmental attitude referring to a person’s awareness of the importance of preserving the environment [
8]. In terms of traveling, people who have a serious concern for the environment will tend to have the intention of visiting ecotourism sites more than other types of tourism because ecotourism has a sustainable aspect by eliminating the negative impact of tourism on the environment.
Previous research has proven that environmental concerns a [
60,
61,
62]. In the context of tourism, such as ecotourism, Pham and Khanh [
8] also shows a positive influence of environmental concern on behavioral intention, which can further encourage tourists’ involvement in ecotourism. In line with the description above and previous studies, the following hypothesis is proposed:
H8. A person’s environmental concern has a positive effect on his or her behavioral ecotourism intention.
Milfont et al. [
63] define time perspective as an individual’s view of the importance of the past, present, and future. Slightly different from the time perspective, the future time perspective is defined as an individual’s picture of himself in the future. An individual’s future time perspective becomes his or her basis in setting goals and plans and evaluating himself or herself [
64]. The future time perspective has various dimensions that not only refer to thoughts about one’s future but also include behaviors, motivations, and feelings about one’s future. The future time perspective is also an influential part of several environmental problems. The situation is due to how environmental issues relate to one’s perception of time; people with a present time perspective may be more concerned with the conveniences that can be felt now without thinking about the impact in the future. People who pay more attention to and care about environmental problems (environmental concern) tend to have a time orientation in the future because they do not want the next generation to suffer the consequences of an overexploited environment. In addition, when considering tourism products, future-oriented people will tend to choose ecotourism because ecotourism provides better benefits to the environment in the future than tourism in general. The more individuals have a future perspective, the more positive their concern for the environment (environmental concern) and their intention to carry out ecotourism behavior.
Several previous studies investigated the effect of time perspective on proenvironmental attitudes and behavior [
65,
66], which show that future-oriented people tend to care more about the environment and act to cope with the environment than present-oriented individuals. Thus, the following two hypotheses were developed as follows:
H9. A person’s future time perspective has a positive effect on his or her environmental concern.
H10. A person’s future time perspective has a positive effect on his or her behavioral ecotourism intention.
Destination image is defined by Phelps [
67] as a person’s perception or picture of an area or location. Tasci and Gartner [
68] revealed that destination image could also be influenced by information from that destination. Another statement mentions destination image as a picture that a person has about a place, from the tourism infrastructure to its cultural, natural, and social attributes [
69]. Destination image is essential for tourism managers to manage because destination image can be used as a marketing strategy, namely, market segmentation division, which is the key that influences tourists’ attitudes to visit a tourist destination.
When tourists have a positive destination image of a tourist site, they are more likely to have the intention to visit that location. In addition, an individual’s description of an ecotourism site as an environmentally friendly tourist destination can trigger his or her environmental concern. This idea is in line with research by Pham and Khanh [
8], which found a positive relationship between ecodestination image and environmental concern. Therefore, the following two final hypotheses are proposed:
H11. A person’s ecodestination image has a positive effect on his or her behavioral ecotourism intention.
H12. A person’s ecodestination image has a positive effect on his or her environmental concern.
3.2. Instrument Development
The research used conclusive research, which was conducted to determine, evaluate, and choose the best course of action from a situation through hypothesis testing, whose results can help decision making. The study collected data from October 2020 to January 2021. The research was conducted through the distribution of online questionnaires because it adhered to boundaries that determined that the subjects studied were respondents who, as tourists, had visited the object of research, namely, ecotourism sites in Banyuwangi Regency. The procedure started with preparing a questionnaire, conducting a pilot test, and distributing questionnaires to respondents. The pilot test was conducted on 20 respondents via Google Forms. The trial was conducted by distributing online questionnaires to respondents. Items on the questionnaire are subject to change after the pilot test. The sampling technique used was a nonprobability sampling technique with convenience sampling. The questionnaires were distributed to obtain respondents’ answers regarding tourists’ behavioral intentions to engage in ecotourism. The questionnaire was distributed through a self-administered questionnaire (filling out questionnaire I).
The study used the sample-to-variable ratio, included in the item–sample ratio category, to determine the number of samples. The most recommended ratio for taking the sample size is 20:1, where 20 is n or the number of samples, and 1 is |Xn| = number of variables. This study used a minimum sample of 220 respondents from 20 × 11 variables. The criteria for respondents in this study were domestic tourists who had visited the ecotourism site of Banyuwangi Regency at least once in the last three years and were at least 17 years old, which is considered to be the cut-off for adulthood, because subjects older than 17 are considered to have more mature reasoning and thinking to digest the questions presented in the research questionnaire.
This study measures a model consisting of several research variables. The independent variables used in this study are perceived behavioral control, subjective norm, environmental attitude, ecotourism self-identity, biosphere value, perceived ecotourism usefulness, environmental knowledge, environmental concern, future time perspective, and destination image. The dependent variable in this study is ecotourism behavioral intention. The respondents were asked to choose responses on the 5-point Likert scale, ranging from 1, as “I strongly disagree” to 5, as “I strongly agree”. The operational variables and questionnaire details are shown in
Table 1.
Researchers distributed pilot test questionnaires to 40 respondents who met the criteria. After the pilot test was distributed and the results were processed, it was found that the respondents had a good understanding of the proposed questionnaire and that no problems could significantly change the contents of the questionnaire. Data collection in this study was carried out through the distribution of online questionnaires by utilizing the Google Forms feature. The online questionnaire can be accessed via the linktr.ee/bantuskripsirani. The instrument was distributed within the period of December 2020 to January 2021. Social media platforms such as Line, WhatsApp, Twitter, and Instagram were used. Massively, most questionnaires were distributed via Instagram, where the questionnaires were distributed using the instastory feature in the form of video posters by several research partner accounts and large accounts, such as @bwi24jam, and by sending personal messages via Instagram’s Direct Messaging feature, where respondents were obtained by searching the location post “Banyuwangi” and hashtags #alaspurwo, #sukamade, and #kawahijen. Respondents who passed the screening stage and filled out the questionnaire to the end had the opportunity to receive a giveaway. The giveaways that are drawn are in the form of e-walled balances, which respondents freely choose.
