      Abstract
      Desmos chinensis Lour. merupakan tumbuhan anggota famili Annonacae yang memiliki banyak manfaat. Tumbuhan ini berkhasiat sebagai antibakteri, antibiotik, antirematik, antispasmodik dan analgesik. Akan tetapi, keberadaan tumbuhan Desmos chinensis Lour. di lingkungan saat ini sudah sulit ditemukan. Analisis autekologi digunakan untuk menjelaskan ekologi Desmos chinensis Lour. di habitat aslinya. Data tersebut sangat diperlukan untuk pengembangan jenis tumbuhan ini di masa depan. Penelitian ini bertujuan untuk mempelajari interaksi spesies Desmos chinensis Lour. dengan lingkungannya. Metode penelitian yang digunakan untuk mengetahui struktur tegakan menggunakan metode transek dan kuadran. Indeks nilai penting Desmos chinensis Lour. di lokasi pengamatan yang cukup besar mengindikasikan spesies tersebut memiliki peranan yang penting bagi lingkungan sekitarnya. Kandungan nitrogen dan fosfor dalam tanah terrmasuk rendah, namun spesies tumbuhan Desmos chinensis Lour. dapat beradaptasi dengan baik di lingkungan tempat tumbuhnya. Nilai indeks keanekaragaman (H’) dan indeks kemerataan (E) di lokasi pengamatan termasuk rendah, hal itu menunjukkan lokasi ditemukannya spesies tumbuhan Desmos chinensis Lour. memiliki spesies tumbuhan yang kurang bervariasi di sekitarnya dan tidak ada spesies yang mendominasi pada tiap plot pengamatan. Hasil analisis menunjukkan, faktor lingkungan yang paling berpengaruh terhadap kelimpahan tumbuhan Desmos chinensis Lour. adalah intensitas cahaya. Kata kunci: Indeks nilai penting, intensitas cahaya, kuadran, mikroklimat, transek
       
      Desmos chinensis Lour. is a plant species belong to the Annonacae family that has many benefits. This plant has antibacterial, antibiotic, antirheumatic, antispasmodic and analgesic properties. However, the existence of Desmos chinensis Lour. in the environment is now difficult to find. Autecological analysis is used to explain the ecology of Desmos chinensis Lour. in its natural habitat. This data is very necessary for the development of this plant species in the future. This study aims to study the interaction of Desmos chinensis Lour. species with its environment. The research method used to determine the structure of the vegetations using transect and quadrant methods. The significant value index of Desmos chinensis Lour. at the observation location indicates that the plant has an important role in the surrounding environment. Nitrogen and phosphor content in the soil is low, however the Desmos chinensis Lour. plant species can adapt well to the environmental where it grows. The value of diversity index (H’) and evenness index (E) at the observation location is low, it shows the location where Desmos chinensis Lour. plant species are found with less varied plant species around them and no dominant species on each observation plot. The results of the analysis showed that the environmental factor that most influenced the abundance of Desmos chinensis Lour. was light intensity. Keywords: Importance value index, light intensity, microclimate, quadrant, transect
