ABSTRACT
Telah dilakukan penelitian keanekaragaman tumbuhan bahan papan di pekarangan berdasarkan perspektif masyarakat Sunda Desa Ciburial, Kecamatan Cimanggu, Banten. Penelitian bertujuan untuk mengetahui pemanfaatan dan keanekaragaman tumbuhan bahan papan berdasarkan perspektif masyarakat Sunda dan mengetahui indeks nilai penting INP spesies tumbuhan bahan papan di pekarangan Desa Ciburial. Metode yang digunakan meliputi wawancara semi struktural dan analisis vegetasi dengan teknik sampling kuadrat. Berdasarkan hasil wawancara diketahui bahwa masyarakat Sunda di Desa Ciburial mengenal dan memanfaatkan 37 spesies dari 18 famili tumbuhan sebagai bahan papan. Tumbuhan bahan papan tersebut merupakan tumbuhan hasil budidaya masyarakat Desa Ciburial di pekarangan. Bagian tumbuhan yang dimanfaatkan untuk bahan papan ialah batang kayu. Penggunaan batang kayu tumbuhan dibedakan atas lima kelompok berdasarkan komponen bangunan yaitu komponen atap, dinding, lantai, pintu dan jendela. Berdasarkan hasil analisis vegetasi, terdapat 44 spesies dari 20 famili tumbuhan yang ditemukan di pekarangan. Indeks Nilai Penting INP tertinggi dimiliki oleh Swietenia mahagoni yang berada pada tingkat semai 57,32 dan tiang 47,04 . Sementara itu, Sandoricum koetjape memiliki INP tertinggi 44,46 pada tingkat pancang. Selanjutnya, INP tertinggi 39,44 pada tingkat pohon dimiliki oleh Cocos nucifera. Kata Kunci : Analisis vegetasi, Banten, indeks nilai penting, komponen bangunan, pekarangan, tumbuhan bahan papan.xiii 74 halaman ; 12 lampiran; 15 gambar; 1 tabelDaftarPustaka : 73 1976-2016.

ABSTRACT
Research regarding plant diversity of building materials in yard based on Sundanese community perspectives in Ciburial Village, Cimanggu Sub district has been done. This research was aimed to find out the utilization, diversity and importance value index of plant species that used as building materials based on Sundanese community perspectives in Ciburial Village yard. This research used semi structured interviews and vegetation analysis with quadrat sampling technique. The interview results shown that Sundanese Community is known and used thirty seven 37 plant species from eighteen 18 families as building materials. These plants have been cultivated by Sundanese Community in Ciburial Village. Tree trunk was the part of the plant that used as building materials. The used of logs have been distinguished into five components, i.e. roof, wall, floor, door and window. Vegetation analysis results found forty four 44 plant species from twenty 20 families in yard. Swietenia mahagoni has the highest importance value index in seedling 57,32 and sapling 47,04 stages, Sandoricum koetjape in small tree 44,46 stage and Cocos nucifera in tree 39,44 stage.
