<![CDATA[ABSTRACT Student Organizations (Ormawa) serve as an important platform for developing students' interests, talents, and soft skills beyond academic activities. However, information regarding the profiles, work programs, and registration procedures of various student organizations at Semarang State Polytechnic has been scattered and unsystematic, making it difficult for new students to gain a comprehensive overview when choosing an organization that matches their interests and talents. This study aims to develop a student organization catalog book as an informational and orientation medium for new students at Semarang State Polytechnic. This research employed the Research and Development (R&D) method using the ADDIE model, which consists of five stages: analysis, design, development, implementation, and evaluation. The research subjects included subject-matter experts, media experts, student organization administrators, and new students at Semarang State Polytechnic. Data were collected through observation, interviews, questionnaires, and documentation, then analyzed using descriptive qualitative and quantitative techniques. The results showed that the developed catalog book was rated highly feasible by both the subject-matter and media experts, and received a very positive response from new students during the trial phase. The product proved effective in helping new students understand the diversity of available student organizations and facilitating the process of selecting an organization that aligns with their individual interests and talents. This study recommends the sustained use of the catalog book in new student orientation programs, as well as the development of a digital version in future research to broaden the reach of information distribution.

Namun, informasi mengenai profil, program kerja, dan alur pendaftaran berbagai Ormawa di Politeknik Negeri Semarang selama ini tersebar secara tidak sistematis, sehingga menyulitkan mahasiswa baru dalam memperoleh gambaran menyeluruh untuk menentukan pilihan organisasi yang sesuai dengan minat dan bakatnya. Penelitian ini bertujuan untuk mengembangkan buku katalog Ormawa sebagai media informasi dan orientasi bagi mahasiswa baru Politeknik Negeri Semarang. Penelitian ini menggunakan metode penelitian dan pengembangan (Research and Development/R&D) dengan model ADDIE, yang terdiri atas lima tahap, yaitu analisis, desain, pengembangan, implementasi, dan evaluasi. Subjek penelitian meliputi ahli materi, ahli media, pengurus Ormawa, dan mahasiswa baru Politeknik Negeri Semarang. Pengumpulanm data dilakukan melalui observasi, wawancara, angket, dan dokumentasi, kemudian dianalisis secara deskriptif kualitatif dan kuantitatif. Hasil penelitian menunjukkan bahwa buku katalog Ormawa yang dikembangkan dinyatakan sangat layak berdasarkan penilaian ahli materi dan ahli media, serta memperoleh respons yang sangat positif dari mahasiswa baru pada tahap uji coba. Produk ini terbukti efektif membantu mahasiswa baru memahami keberagaman Ormawa yang tersedia dan memudahkan proses pemilihan organisasi yang sesuai dengan minat dan bakat masing-masing. Penelitian ini merekomendasikan pemanfaatan buku katalog Ormawa secara berkelanjutan dalam kegiatan orientasi mahasiswa baru serta pengembangan versi digital pada penelitian selanjutnya agar jangkauan distribusi informasi menjadi lebih luas.
