      Abstract
      Tumbuhan parasit adalah tumbuhan yang memperoleh nutrisi dari inangnya. Salah satu jenis yang mendominasi di Kampus IPB University, Dramaga, ialah Dendrophthoe pentandra (L.) Miq. dari famili Loranthaceae. Keberadaan tumbuhan parasit dapat menimbulkan dampak negatif terhadap tumbuhan inang maupun lingkungan sekitar. Oleh karena itu, penelitian ini bertujuan mengetahui distribusi D. pentandra di Kampus IPB Dramaga, tingkat kerusakan inang, serta mode interaksi parasit–inang. Metode yang digunakan meliputi penjelajahan pada jalur pejalan kaki, identifikasi tumbuhan inang dan parasit di rentang ketinggian 1,5–1,7 m, pengukuran tingkat kerusakan, dan observasi interaksi melalui pemotongan cabang terinfeksi. Hasil penelitian menunjukkan bahwa D. pentandra ditemukan pada dua spesies inang, yaitu Annona montana Macfad. dan Codiaeum variegatum (L.) Rumph. ex A.Juss. dengan total empat lokasi pengamatan. Tingkat kerusakan yang tercatat cukup tinggi, yaitu 97,3% ± 2,5 pada A. montana dan 93,4% ± 0,3 pada C. variegatum. D. pentandra ditemukan menempel pada cabang inang dan tampak seolah tumbuh di ujung cabang inangnya. Pengamatan pada potongan tonjolan cabang terinfeksi memperlihatkan keberhasilan penetrasi haustorium D. pentandra yang ditandai warna hitam akibat kematian jaringan inang. Tingkat kerusakan yang tinggi serta keberhasilan penetrasi menunjukkan intensitas parasitisme D. pentandra terhadap inangnya.
       
      Parasitic plants are plants that obtain nutrients from their hosts. One species that dominates the IPB University campus in Dramaga is Dendrophthoe pentandra (L.) Miq. from the Loranthaceae family. The presence of parasitic plants can have negative impacts on host plants and the surrounding environment. Therefore, this study aims to determine the distribution of D. pentandra at the IPB University Dramaga Campus, the extent of host damage, and the mode of parasite–host interaction. The methods used include exploring walking trails, identifying host and parasitic plants at heights ranging from 1.5 to 1.7 meters, measuring the extent of damage, and observing interactions through the cutting of infected branches. The results of the study showed that D. pentandra was found on two host species, Annona montana Macfad. and Codiaeum variegatum (L.) Rumph. ex A.Juss. with a total of four observation sites. The recorded damage levels were quite high, at 97.3% ± 2.5 on A. montana and 93.4% ± 0.3 on C. variegatum. D. pentandra was found attached to the host branches and appeared to grow at the tips of the host branches. Observations of infected branch protrusions revealed successful penetration of D. pentandra haustoria, marked by black discoloration due to host tissue death. The high damage levels and successful penetration indicate the intensity of D. pentandra's parasitism on its hosts.
