Pendidik sangat berperan penting dalam mengembangkan perangkat pembelajaran yang menarik dan sesuai dengan kebutuhan siswa. Tujuan penelitian ini adalah untuk mengetahui validitas, kepraktisan dan efektifitas produk media katalog peralatan laboratorium biologi sebagai sumber belajar siswa. Model pengembangan yang digunakan dalam penelitian ini adalah model Analysis, Design, Development, Implementation and Evaluation (ADDIE). Uji coba produk dilaksanakan dalam skala terbatas dengan subjek penelitian yang terdiri dari 25 siswa kelas X MIPA 3 dan 2 guru biologi SMA Negeri 3 Majene. Data validitas media katalog didapatkan dari validator ahli media dan ahli materi, data kepraktisan didapatkan dari hasil analisis angket respon guru dan siswa terhadap media katalog, sedangkan data efektifitas didapatkan dari hasil analisis data hasil belajar kognitif siswa. Hasil analisis data validitas media katalog menunjukkan tingkat validitas sebesar 4,2 yang termasuk kategori valid, sedangkan hasil analisis data kepraktisan berdasarkan angket respon guru dan siswa sebesar 96,2% dan 80,7% dengan kategori sangat praktis serta hasil analisis berdasarkan tes hasil belajar kognitif diperoleh sebesar 72% dengan kategori efektif. Penelitian dan pengembangan ini menunjukkan bahwa media katalog peralatan laboratorium biologi valid, praktis dan efektif untuk digunakan sebagai sumber belajar siswa.
Educators play a very important role in developing learning tools that are iteresting and appropriate to students needs.. The aim of this research is to knowing the validity, practicality and effectiveness of equipment catalog media products biology laboratory as a student learning resource. Development model used in this research is the model Analysis, Design, Development, Implementation and Evaluation (ADDIE). Product trials are carried out on a limited scale with research subjects consisting of 25 class X students MIPA 3 and 2 biology teachers at SMA Negeri 3 Majene. Catalog media validity data obtained from validators, media experts and material experts, practical data was obtained from the results of questionnaire analysis of teacher and student responses to catalog media, while the effectiviness data was obtained from the results of data analysis of cognitive learning outcomes student. The results of data analysis on the validity of the media catalog show the level of validity of 4,2 which is inculded in the valid category, while the results of data analysis practicality based on teacher and student response questionnaires of 96,2% and 80,7% with a very practical category and analysis results based on learning outcomes tests cognition was obtained at 72% in the effective category. Research and this development shows that the media catalogs laboratory equipment biology is valid, practical, and effective to be used as a student learning resource.
