Abstract

ABSTRAK Pentingnya memiliki alat ukur yang valid untuk mengukur sikap lingkungan dalam konteks Indonesia, mengingat isu pelestarian lingkungan yang semakin krusial, terutama bagi generasi muda. Penelitian ini bertujuan untuk mengadaptasi dan memvalidasi alat ukur Environmental Attitudes Inventory (EAI) yang mengacu pada teori Milfont (2010) kedalam konteks budaya Indonesia. Metode penelitian yang digunakan adalah kuantitatif dengan teknik nonprobability sampling yang didalamnya menggunakan teknik Convenience sampling. Proses adaptasi meliputi prakondisi, pengembangan, konfirmasi, administrasi, skor dan interpretasi. Sampel penelitian terdiri dari 311 responden yang merupakan generasi Z di Indonesia dengan rentang usia 14 sampai 29 tahun. Data dianalisis menggunakan Rasch Model dalam software Winstep 3.47. Hasil menunjukkan bahwa alat ukur ini unidimensionalitas, reliabilitas menunjukkan memadai (item reliability .99, person reliability .81, alpha cronbach .83 dan omega mcdonald .83), dan validitas konstruk menunjukkan 22 aitem fit dengan 2 aitem misfit. Kesimpulannya, alat ukur EAI yang telah diadaptasi dapat digunakan untuk mengukur sikap lingkungan pada generasi Z di Indonesia. Kata kunci: Generasi Z, Rasch Model, Sikap Lingkungan. ABSTRACT The importance of having a valid instrument to measure environmental attitudes within the Indonesian context is underscored by the increasingly critical issue of environmental preservation, particularly among the younger generation. This research aims to adapt and validate the Environmental Attitudes Inventory (EAI), based on Milfont's theory (2010), within the Indonesian cultural context. The research method employed is quantitative, utilizing a nonprobability sampling technique, specifically convenience sampling. The adaptation process includes pre-conditions, development, confirmation, administration, and interpretation. The research sample consists of 311 Generation Z respondents in Indonesia, aged 14 to 29 years. Data were analyzed using the Rasch Model within the Winsteps 3.47 software. Results indicate scoring, that the instrument demonstrates unidimensionality. Reliability is adequate (item reliability .99, person reliability .81, Cronbach's alpha .83, and Mcdonald 's omega .83). Construct validity analysis shows that 22 items fit the model, while 2 items exhibit misfit. In conclusion, the adapted EAI instrument can be used to measure environmental attitudes among Generation Z in Indonesia. Keywords: Generation Z, Rasch Model, Environmental Attitudes.
