      Abstract
      Rafflesia patma Blume merupakan tumbuhan langka dan dilindungi yang tersebar di pulau Jawa, salah satunya di Cagar Alam Pangandaran. R. patma memiliki ciri biologis yang berbeda dengan tumbuhan lain yaitu memerlukan kondisi lingkungan tertentu untuk mendukung perkembangbiakan dan pertumbuhannya. Tujuan penelitian ini yaitu untuk mendeskripsikan kondisi dan menganalisis faktor biotik juga abiotik pada habitat R. patma di Cagar Alam Pangandaran. Metode yang digunakan adalah purposive sampling dengan plot lingkaran berukuran jari-jari 17,8 m. Hasil identifikasi ditemukan 202 individu pada 15 plot penelitian yang terdiri dari kuncup mati, kuncup hidup dan mekar mati. Tumbuhan inang yang ditemukan merupakan spesies Tetrastigma leucostaphylum. Kondisi vegetasi yang mendominasi pada tingkatan pohon, pancang dan semai yaitu Vitex pubescens, Dyospyros oblonga dan Flacourtia rukam. Satwa yang ditemukan pada habitat R. patma sebanyak 8 spesies. Habitat R. patma ditemukan pada ketinggian 40 – 120 mdpl, kemiringan 4 – 35 %, jenis tanah lempung berwarna coklat kemerahan sampai abu-abu kehitaman, suhu rata-rata 27,4ºC, kelembapan 60-94% dan nilai indeks luas daun berkisar 1,82 – 2,15.
       
      Rafflesia patma Blume is a rare and protected plant that is spread across the island of Java, one of which is the Pangandaran Nature Reserve. R. patma has different biological characteristics from other plants, namely that it requires certain environmental conditions to support its reproduction and growth. The aim of this research is to describe the conditions and analyze biotic and abiotic factors in the R. patma habitat in the Pangandaran Nature Reserve. The method used was purposive sampling with a circle plot measuring 17.8 m radius. The identification results found 202 individuals in 15 research plots consisting of dead buds, live buds and dead blooms. The host plant found was the Tetrastigma leucostaphylum species. The vegetation conditions that dominate at the tree, sapling and seedling levels are Vitex pubescens, Dyospyros oblonga and Flacourtia rukam. Eight types of animals were found in the R. patma habitat. The habitat of R. patma is found at an altitude of 40 – 120 meters above sea level, slope 4 – 35%, clay soil type reddish brown to blackish gray, average temperature 27.4ºC, humidity 60-94% and leaf area indeks value around 1, 82 – 2.15.
