1. Introduction
Environmental problems caused by human behavior—that is, those less concerned with the environment—cause environmental pollution [
1,
2]. One cause of environmental problems that can contribute to environmental damage is humans who do not feel responsible for the environment, whether it be because they do not care about the environment or because they do not want to take part in protecting and preserving it. Environmental problems might occur because individuals still have a low level of environmental ethics and environmental care attitudes [
3], resulting in environmental problems such as river pollution [
4], waste pollution [
5], floods [
6,
7,
8], industrial waste pollution [
9,
10,
11], forest degradation [
12], seawater pollution [
13], and drought [
14]. All environmental problems have the potential to impact environmental quality [
15] and even climate change [
16].
The community’s participation in environmental maintenance and management in the Pati Regency is still ineffective, resulting in pollution. Based on data and information from the Environment Agency in the Pati Regency, it has been discovered that 95 tons of inorganic waste were produced, which were stockpiled in the landfill (Tempat Pembuangan Akhir Sampah–TPA) in Sukohajo Village, Margorejo District, Pati Regency [
17]. This inefficient environmental management results in waste pollution [
11]. Environmental pollution can be prevented by reducing the quantity of waste produced (reduce), reusing it for the same purpose (reuse), and recycling it (recycle) [
18,
19]. For instance, reducing materials that are difficult to decompose, or that degrade quickly, and instead using unused waste can help reduce waste pollution. Meanwhile, recycling allows waste, which is frequently perceived as being useless, to be put to new use.
Through environmental education, it is also possible to influence human behavior that is less careful with the environment [
20,
21,
22]. The Adiwiyata school curriculum includes environmental education with the aim of establishing a school that is cultured and cares about the environment [
23,
24]. This is supported by the Minister of Environment’s Regulation No. 5 of 2013 regarding the Guidelines for the Implementation of the Adiwiyata Program, where the Adiwiyata School is a program that engages all stakeholders in schools and the community to increase students’ environmental care attitudes. Environmental sensitivity is a fundamental mindset that must be developed in all school members [
25,
26]. Environmental care attitudes can be found in communities that share the same goals and values. School members who want to preserve the school environment are expected to be leaders in establishing a clean and comfortable environment, as well as promoting environmental care attitudes on a larger scale, particularly in the community. Individuals with a high environmental care attitude are able to anticipate global environmental issues that have emerged in recent years [
27,
28].
Environmental care attitudes must be implemented early on in future generations in order to establish positive habits for the younger generation [
29,
30]. Various studies have been conducted to investigate the importance of environmental care attitudes in education, such as the students’ environmental care attitudes at the Ar-Rohmah Islamic Boarding School in Malang, which are still considered low [
31]. Furthermore, in Pekanbaru, some students are found to be littering trash in the schoolyard [
32]. It was also discovered that students in the Pati Regency littered, as evidenced by the scattered trash in the schoolyard [
33].
Environmental care attitudes are necessary for resolving environmental issues and promoting a nice and clean environment [
34]. Environmental care attitude is measured using the new ecological paradigm (NEP) scale, which has five components: (1) limits to growth; (2) anti-anthropocentrism; (3) balance of nature; (4) anti-exemptionalism; and (5) eco-crisis [
35,
36]. The new ecological paradigm (NEP) scale is used to measure environmental care attitudes due to its advantages, such as being viewed as a credible data collection tool to determine environmental care attitudes, and it is frequently used as a measurement instrument in different countries [
35,
37,
38]. According to research conducted in Greece, the new ecological paradigm (NEP) scale has the consistency to assess gender differences based on environmental care attitudes [
39,
40]. Moreover, research conducted in Brazil revealed that the new ecological paradigm (NEP) scale has been demonstrated to be a valid instrument for measuring environmental care attitudes [
41].
Indicators in the new ecological paradigm (NEP) are suitable for assessing environmental care attitudes. Indicators of limits to growth can be used to determine human environmental knowledge and attitudes. Furthermore, indicators of anti-anthropocentrism can be used to identify humans’ roles in using natural resources and the environment. Indicators of the balance of nature can determine behavior in balancing environmental sustainability. An indicator of anti-exemptionalism is a sense of responsibility for regulating and using the environment. Indicators of eco-crisis can determine behavior in preventing environmental damage.
Gender differences in the perception of environmental care attitudes are one of the issues that are emerging [
42,
43]. Moreover, gender socialization theory demonstrates that environmental care attitudes are determined by the socialization process shaped by a particular gender’s cultural norms [
44]. According to these findings, there are differences between men and women. Women are more empathetic, cooperative, and willing to assist than men [
45]. Men have courageous personalities, enjoy challenges and competition, and are communicative, so they enjoy discussing ideas in online forums [
46].
Therefore, the following objectives are investigated in this study: (1) to evaluate the implementation of the environmental curriculum in Adiwiyata schools; (2) to analyze students’ environmental care attitudes in Adiwiyata schools in the Pati Regency using the new ecological paradigm (NEP) scale; and (3) to examine students’ environmental care attitudes in Adiwiyata schools in the Pati Regency related to gender differences. Research on students’ environmental care attitudes in the Pati Regency is expected to be one of the references for implementing environmental education in schools.
2. Materials and Methods
The aims of this research are: (1) to evaluate the implementation of the environmental curriculum in Adiwiyata schools; (2) to analyze students’ environmental care attitudes in Adiwiyata schools in the Pati Regency using the new ecological paradigm (NEP) scale; and (3) to examine students’ environmental care attitudes related to gender differences in Adiwiyata schools in the Pati Regency. Students’ environmental care attitudes are assessed using survey techniques and questionnaires as data collecting instruments. Research subjects were selected using a purposive sampling technique (
Table 1). Three Adiwiyata Public High Schools in the Pati Regency were chosen as research subjects: SMA Negeri 1 Pati, SMA Negeri 2 Pati, and SMA Negeri 3 Pati. Research references are used to determine research locations based on the frequency of environmental issues in the school environment. In addition, the research location was determined based on the focus or topic of the Adiwiyata school. The research subjects were selected using a purposive sampling technique and divided into two groups based on the average score of student learning outcomes. Research locations with two or more classes will make it easier for researchers to choose research subjects. The criteria were used to determine research subjects in terms of the average value of high and low learning outcomes. Of the two research classes that were selected, it was determined that the first class was the class that had the highest average learning outcomes, and the second class was the class that had the low average learning outcomes. The sample in terms of gender was determined by gender status within two classes that were selected as research subjects.
A questionnaire was used to collect data for this research. For this research, students were given several written statements. The assessment of environmental care attitudes is based on a Likert scale with four response options: strongly agree (SA), agree (A), disagree (D), and strongly disagree (SD) (
Table 2). Questionnaires were used to identify students’ environmental care attitudes and were constructed with statements related to environmental care attitudes toward their school environment. Respondents were instructed to write a checkmark (√) next to one of the four alternative answers.
This study measures environmental care attitudes based on the new ecological paradigm (NEP) scale, which consists of five aspects: (1) limits to growth to determine human knowledge of environmental care attitudes; (2) anti-anthropocentrism to determine the role of humans in the utilization of natural resources and the environment; (3) balance of nature to determine behavior in balancing environmental sustainability; (4) anti-exemptionalism to determine the sense of responsibility for managing the environment and utilizing the environment; and (5) eco-crisis to determine behavior in preventing environmental damage [
35,
36].
The research instrument was tested on 40 students to determine the validity and reliability of the environmental care attitude questionnaire. To ensure the new ecological paradigm (NEP) questionnaire has valid and reliable values, the researchers took the Pearson correlation validity test and Cronbach’s alpha reliability test with the Windows version of SPSS 22. The validity of the new ecological paradigm (NEP) questionnaire is determined based on the validity value of the r count > r table. The determination of the r table is based on the number of respondents, namely 40 students, which means that the r table has a value of 0.312 [
48].
Table 3 shows that the new ecological paradigm (NEP) questionnaire has a value of r count > r table = 0.312. The Pearson correlation validity test results show that the new ecological paradigm (NEP) instrument is proven valid and can be used to obtain data on environmental care attitudes. The results of the validity and reliability tests of the environmental care attitudes questionnaire are shown in the following
Table 3.
The reliability of the new ecological paradigm (NEP) questionnaire was determined based on Cronbach’s alpha > r table [
48]. Decision-making on reliability using Cronbach’s alpha reliability coefficient criteria (1) very high (0.80–1.00), (2) high (0.60–0.79), (3) sufficient (0.040–0.59), (4) low (0.20–0.39), and (5) very low (0.00–0.19) [
49]. The questionnaire is declared reliable if the reliability coefficient of Cronbach’s alpha is > 0.60.
Table 3 shows that each indicator from the new ecological paradigm (NEP) has a Cronbach’s alpha value > r table = 0.312 and has a Cronbach’s alpha reliability coefficient value > 0.60. This analysis shows that the environmental care attitude instrument is reliable, and each new ecological paradigm (NEP) indicator includes a high Cronbach’s alpha reliability coefficient. The data analysis step is carried out after the environmental care attitudes instrument has been proven to be valid and reliable. The measurement uses a variety of scores to determine environmental care attitudes, which are then analyzed using the percentage formula [
50,
51] (
Table 4).
where:
NP = percentage
n = observation results
sm = maximum score
The Mann-Whitney test was used to identify gender differences because the data was not normal (
p 0.000 <
p 0.05). The Mann-Whitney test is one of the most effective non-parametric tests, with high probability and statistically significant results [
52]. Quantitative data analysis was performed using the SPSS application version 22 for Windows.
4. Discussion
Environmental problems are problems caused by environmental degradation and are affected by human attitudes and caring for the environment [
34]. Environmental care is associated with the mutual connection between humans and environmental attitudes [
80]. In order to maintain life and conduct daily activities, humans are closely attached to their environments [
81,
82]. The relationship between humans and the environment can become problematic when humans exploit the environment for their personal benefit and disregard the sustainability of nature. Therefore, environmental care must be taught to children from an early age to change attitudes toward environmental issues [
83,
84,
85]. Environmental care attitudes are so essential that they must be taught in educational programs [
86,
87].
This study examined the implementation of the environmental curriculum in Adiwiyata schools, students’ environmental care attitudes at Adiwiyata High School in the Pati Regency were based on the new ecological paradigm (NEP) scale, and gender differences in students’ environmental care attitudes were based on the new ecological paradigm (NEP) scale. This study indicated that the main objective of Adiwiyata schools is to educate students about environmental care, with an emphasis on fostering environmental literacy so that each student develops environmental care attitudes. Using an environmental education curriculum with environmental care values, Adiwiyata schools have a strategic role in increasing environmental care attitudes [
88]. The teacher plays an important role as a facilitator in developing student behavior patterns and forming environmental care attitudes by implementing an integrated environmental education curriculum in all subjects. This is similar to previous research demonstrating the significance of an environmental education curriculum for students’ educational development [
89,
90]. This argument is supported by studies from various countries. Environmental care attitudes in Canada explain the importance of environmental education in enhancing environmental care attitudes among students [
91]. It is different in India, which explains that environmental education is included in the curriculum and manifests itself in numerous student practices or exercises to protect the environment [
92].
The Adiwiyata program carried out various activities, including the use of greenhouses and environmental activities based on participation, such as using mini-forests, tree planting, and the campaign to reduce plastic waste. The purpose of this activity is to promote environmental literacy and facilitate student learning. Students can become more environmentally aware through interaction with the environment [
93]. According to research conducted in France, greenhouses can enhance students’ environmental awareness [
94]. This differs from research conducted in England, which indicates that the use of greenhouses can reduce gas emissions and stabilize school climate [
95]. In addition, the Adiwiyata program includes environmental activities based on participation that emphasize teaching students to care for the environment. According to behaviorism theory, a routine and self-habituation that is repeated on a daily basis will be instilled and remembered by students, so that the routine that has been carried out will occur subconsciously and immediately [
96,
97]. Behaviorism is considered one of the most effective methods of education for achieving learning objectives, as students tend to think, conduct, and act following environmental norms [
98,
99].
Furthermore, the analysis of students’ environmental care attitudes at Pati Regency high schools is included in the moderate category. The indicator of the balance of nature has the highest environmental care attitude index value when compared to the indicators of limits to growth, anti-anthropocentrism, anti-exemptionalism, and eco-crisis, as shown in
Table 5. The indicator of the balance of nature described how human behavior can balance the environmental sustainability [
35]. This study determined that some students no longer have the potential to cause environmental damage in the future. According to research by [
100], students understand the concepts of reduce, reuse, and recycle and contribute to preventing environmental damage and restoring environmental balance.
In addition, an analysis of gender differences based on the new ecological paradigm (NEP) scale demonstrated that women are more concerned with environmental issues than males. This is similar to previous research on environmental care attitudes in China, which revealed that women scored higher [
76].
Figure 3 indicates that women have the highest average scores for the indicators of limits to growth, anti-anthropocentrism, anti-exemptionalism, and eco-crisis.
The indicator of limit to growth showed that women have high knowledge of environmental care attitudes. Several studies, comparatively, indicate that males are more knowledgeable about environmental issues because they have greater access to higher education [
101,
102]. This is influenced by the development of social norms in society. In the past, parents believed that only boys could pursue higher education, but today, many parents believe that girls have the same right to pursue the highest level of education [
103]; following the feminism theory that believes women have the same rights as males in education, the economy, and social life [
104]. In addition, ecological feminism hypothesizes that because women are concerned with environmental issues, they can prevent environmental problems [
105,
106]. Therefore, women have a higher degree of knowledge than men. The roles held by women are empathic and emotional, whereas males are better at regulating their emotions [
107]. The limit to growth indicator has an appeal because there is a finding that the average value obtained from the limit to growth indicator shows a high value. However, based on the Mann-Whitney test shows that the limit to growth indicator has no significant difference between men with women.
The indicator of Anti-anthropocentrism described the role of women in natural resource utilization and environmental preservation. Sociological theory explains that gender differences are not only biological but also cultural and social [
108]. In a society’s social structure, women and males have distinct roles. In terms of the family, it is the responsibility of women to nurture children, provide affection, and teach environmental awareness to the next generation [
79,
109]. Men, however, prioritize the role of economic providers and market activities, which encourages them to be more skilled, rational, and competitive than women [
110]. Therefore, men score lower than women on the anti-anthropocentrism indicator. The findings in this study have an interest or something unique in that the anti-anthropocentrism indicator has a high average value, but as seen from the Mann-Whitney test, the anti-anthropocentrism indicator shows no significant difference between men and women.
Then, the indicator of anti-exemptionalism indicated that women have a sense of responsibility to regulate and protect the environment. The findings on the exemptionalism indicator show that there is a significant difference based on the Mann-Whitney test. Based on previous research it was found that women have more pro-environmental behavior than men [
111]. Theoretically, gender differences assume a connection between processes and social values. Therefore, women are better able to respect the needs of others and demonstrate altruism in everyday life than men. Altruism is a human attitude that seeks to enhance the well-being of others; however, this altruism appears to be closely linked to environmental management and environmental protection [
44].
In addition, the indicator of eco-crisis demonstrated that women engage in practices that prevent or restore environmental damage and it is proven that women have significant differences compared to men based on the results of the Mann-Whitney test; following prior research indicating that women care about environmental preservation [
42,
112,
113]. This is also in line with the socialization theory statement that women have a stronger and more sensitive “caring ethic” [
114]. The research conducted by Dagher and Singh stated that the environmental care attitudes of female students were higher than those of male students [
42,
115]. Educational activities related to environmental management and utilization are needed for both male and female students. Educational activities consisting of the implementation of environmental education for both male and female students are one of the most effective methods for improving environmental care attitudes. The purpose of environmental education is to establish an awareness of environmental issues in students’ attitudes [
116]. Implementing environmental education in teaching and learning activities creates students with the responsibility to manage and preserve the environment and support sustainable development so that they can later actively participate in addressing environmental problems [
117,
118].
Furthermore, based on the results of the Mann-Whitney test that the anti-exemptionism indicator and the eco-crisis indicator have a significant gender difference between men and women towards environmental care attitudes. First, the anti-exemptionism indicator explains that women have more responsibility towards the environment than men. There are findings in the research that women have a sensitive character and have more feelings than men [
119,
120]. Based on these characters, it is evident that women own environmental awareness behavior. In addition, there are previous research findings that women can have a bond with nature [
121].
Second, the eco-crisis indicator states that women are more pro-environmental in preventing environmental damage than men. This is supported by previous research findings that women participate in pro-environmental activities and adopt more sustainable lifestyles than men [
78,
122]. In line with this statement that research has been conducted in China, by applying sustainable style principles, women show less use of plastic bags and prefer to use reusable bags when shopping [
123].
This study has significant implications for educators, future researchers, and knowledge related to environmental care attitudes. First, in relation to the environmental care attitude of students in the moderate category, where female students have a higher level of environmental care attitude than male students, it is necessary to play the role of implementing environmental education regularly or repeatedly, with the teacher’s encouragement, to significantly influence the strengthening of students’ environmental care attitudes. Based on this study’s findings, environmental education activities need to be focused on men. The first activity is providing knowledge about the environment and introducing the use of natural resources with the principles of sustainable development, introducing the application of environmental management, and providing knowledge of the impact of environmental problems. The second activity directs men to carry out participatory-based environmental activities, such as introducing ways to conserve the environment, manage natural resources and carry out activities to prevent environmental damage by activating the role of 4R + C (refusal, reduce, reuse, recycle, and composting). Then, the implementation of environmental education in learning activities that are integrated into the curriculum is anticipated to strengthen students’ environmental care, allowing them to identify, evaluate, and find solutions to environmental issues and problems. Therefore, to implement environmental education, it must collaborate with school principals, teachers, and students to change students’ environmental care attitudes.
According to the results, this research showed that gender differences play an important role in environmental education and managing the environment. It can be confirmed that women have a high potential for student environmental care attitudes.
Second, teachers must take an active role in enhancing students’ environmental awareness by implementing environment-based teaching materials and directing students to participate in organizations or activities related to the environment. Regularly organize environmental activities, such as competitions about the environment, designing models made from recycled materials, planting trees, and environmental quizzes.
Third, it is expected that this study will contribute to future research. Future researchers can test this study’s hypotheses regarding the implementation of Adiwiyata schools, the environmental care attitudes of Adiwiyata school students, and the analysis of students’ environmental care attitudes using the new ecological paradigm (NEP) scale in terms of gender differences using samples from their own countries.
Fourth, this research is believed to have contributed to knowledge related to environmental care attitudes. The formation of an attitude of caring for the environment can be started from an early age in the future younger generation. Environmental knowledge is needed to form good habits and will impact human attitudes that care and prevent environmental damage. The potential implication for policies and practices in the field is that humans will consciously prevent environmental problems through tree planting, reducing plastic waste, and not disposing of waste in rivers.
This study has limited research subjects because the research subjects were class XI students of the Adiwiyata program in the Pati Regency. Thus, it is necessary to carry out further research with the same scope.
