Penelitian ini bertujuan untuk menganalisis jenis tumbuhan kantong semar berdasakan indeks keanekaragaman di Hutan lindung kota Tarakan dan potensi sebagai sumber belajar Biologi kelas X SMA/MA. Dari hasil penelitian kantong semar di Hutan lindung kota Tarakan terdapat 6 spesies dari 1 family Nepenthaceae yaitu N.hirsuta, N.ampularia, N.mirabilis, N.raflesiana, N.stenophylla dan N.tomoriana. Berdasarkan perhitungan indeks keanekaragaman yang dilakukan, keanekaragaman kantong semar pada kedua stasiun tergolong dalam kategori sedang dengan nilai H' pada stasiun I 1,49 sedangkan pada stasiun II 1,26. Adapun hasil analisis keterkaitan penelitian pada pembelajaran Biologi yaitu pada materi keanekaragaman hayati kompotensi dasar 3.2 mengenai berbagai tingkat keanekaragaman hayati di Indonesia, beserta ancaman dan pelestariannya dan kompetensi dasar 4.2 menyajikan hasil observasi berbagai tingkat keanekaragaman hayati di Indonesia serta usulan upaya pelestariannya.

The present research aimed to analyze the types of pitcher plant based on the index of diversity in the Protected Forest of Tarakan City and the potential as a resource for Biology learning for Class X SMA/MA. From the results of research on pitcher plant in the Protected Forest of Tarakan City, there were 6 species from 1 family of Nepenthaceae, namely, N. hirsuta, N. ampularia, N. mirabilis, N. raflesiana, N. stenophylla, and N. tomoriana. Based on the calculation of the diversity index of the pitcher plant at two stations, it was in the medium category where the H' value at station I was I .49, while at station Il was 1.26. The result of the linkage analysis in Biology learning, namely, the material on biodiversity in Indonesia along with its threats and conservation. It was stated in Basic Competence 4.2.: present the results ofobservations ofvarious levels ofbiodiversity in Indonesia and suggestions for efforts to preserve it.
