<![CDATA[This study aims to develop and determine the feasibility of a bilingual booklet (Indonesian–English) containing local history, flora, fauna, ecosystems, and conservation messages in Banyuwangi. Learning materials that integrate local history, biodiversity, and English are still very limited, even though an integrative approach is essential for creating contextual and meaningful learning. This research employs a simple Research and Development (R&D) method through the stages of needs analysis, development, validation, revision, and limited trial. Research subjects consisted of students from SMP Nahdlatul Wathan Banyuwangi as users, as well as teachers and lecturers as validators. Data were collected through needs assessment questionnaires, expert validation questionnaires, and student response questionnaires, then analyzed using descriptive quantitative methods. The results showed that the developed bilingual booklet received a very feasible assessment from material experts with a percentage of 89.6%, language experts with a percentage of 87.3%, and media experts with a percentage of 91.2%. Student responses to the booklet were also very positive with a percentage of 88.4%. This booklet contains the local history of Banyuwangi, regional biodiversity, and conservation messages presented in two languages. This research produces a validated multidisciplinary learning product that can be used as a contextual learning resource in secondary schools.]]>
