"ABSTRAKPohon kepel (Stelechocarpus burahol) di FMIPA UI sebagian besar (8 dari 9 pohon) ditumbuhi oleh benalu Dendrophthoe pentandra (Loranthaceae). Keberadaan benalu tersebut diduga dapat menyebabkan kerusakan pohon S. burahol. Oleh karena itu, dilakukan penelitian yang bertujuan mengetahui tingkat kerusakan S. burahol akibat ditumbuhi benalu. Benalu yang tumbuh pada S. burahol dapat menyebabkan kerusakan morfologi dan anatomi. Kerusakan morfologi dapat diketahui dengan menghitung selisih keliling cabang pohon S. burahol bagian proksimal dan distal. Kerusakan anatomi dapat dilihat berdasarkan potongan membujur haustorium benalu yang menempel pada cabang S. burahol. Hasil penelitian menunjukkan nilai kerusakan pohon S. burahol tertinggi sebesar 94,3% (sangat rusak), sedangkan berdasarkan pengamatan potongan membujur haustorium benalu terlihat bagian jaringan cabang S. burahol yang mengalami kerusakan akibat penetrasi haustorium benalu (collapsed zone). Benalu D. pentandra yang tumbuh pada S. burahol dalam jangka panjang akan menyebabkan kematian yang berakibat kepada penurunan populasi pohon S. burahol di FMIPA UI.

ABSTRACTMajority of Kepel tree (Stelechocarpus burahol) in FMIPA UI (8 of 9 trees) overgrown by mistletoe Dendrophthoe pentandra (Loranthaceae). The mistletoe suspected to cause damage to S. burahol trees. Therefore, the research to determine the level of damage as a result of overgrown mistletoe on S. burahol is done. The mistletoe that grows on S. burahol can cause morphology and anatomy damage. Morphology damage can be determined by calculating the difference in circumference of tree branches S. burahol on proximal and distal parts. Anatomy damage can be viewed by piece of longitudinal section haustorium of mistletoe that attaches to the S. burahol branch. The results showed that the highest value of damage to S. burahol trees is 94.3% (very damaged), whereas based on longitudinal section part of the S. burahol branch tissue damaged by penetration haustorium of mistletoe (collapsed zone) could be seen. Mistletoe of D. pentandra that grows on S. burahol in the long time will lead to death and caused the population of S. burahol trees in FMIPA UI declined."

"Beji merupakan salah satu kecamatan di Kota Depok yang mengalami perubahan penggunaan lahan cukup besar akibat ekspansi aktivitas perkotaan. Hal tersebut menyebabkan tidak banyak lahan yang tersisa untuk ditanami pepohonan. Beberapa penelitian yang telah dilakukan di daerah urban lainnya menunjukkan hasil yang beragam mengenai tingkat keanekaragaman jenis pohon pada kawasan jalan. Beberapa wilayah di Kota Depok masih memiliki kawasan hijau salah satunya di area jalan raya, taman, dan permukiman di Kecamatan Beji. Penelitian ini bertujuan untuk membandingkan tingkat keanekaragaman pohon pada kawasan jalan di area jalan raya, taman, dan permukiman di Kecamatan Beji, Kota Depok. Pengambilan sampel pohon dilakukan dengan metode belt transect. Setiap pohon yang ditemui di dalam plot sampling diukur DBH dan diidentifikasi untuk mengetahui komposisi dan kekayaan jenis pohon di setiap area, serta untuk menghitung Indeks Nilai Penting (INP) pohon, indeks keanekaragaman Shannon-Wiener, indeks kemerataan dan indeks kesamaan Sorensen. Selain itu, data parameter lingkungan seperti suhu, kelembapan udara, dan pH tanah juga diukur di ketiga area untuk mengetahui kondisi lingkungannya masing-masing. Berdasarkan data yang diperoleh, diketahui bahwa Swietenia macrophylla menjadi jenis pohon paling melimpah di lokasi penelitian, namun lebih terkonsentrasi di area jalan raya. Hasil perhitungan INP menunjukkan bahwa Swietenia macrophylla, Tectona grandis, dan Pterocarpus indicus berturut-turut merupakan jenis pohon yang paling dominan di area jalan raya, taman, dan permukiman. Secara umum tingkat keanekaragaman di area jalan raya dan permukiman termasuk kategori sedang, sedangkan area taman termasuk kategori rendah. Berdasarkan perhitungan indeks kemerataan, sebaran jumlah individu jenis pohon di area permukiman cenderung lebih merata daripada di area jalan raya dan taman. Pasangan area jalan raya-permukiman memiliki tingkat kemiripan tertinggi berdasarkan perhitungan indeks kesamaan Sorensen. Pengukuran parameter lingkungan di ketiga area menujukkan hasil yang cukup bervariasi antar area

Beji is one of the districts in Depok City that has experienced great land-use changes due to the expansion of urban activities. It causes not much land left for planting trees. Several studies that have been conducted in other urban areas have shown mixed results regarding the level of tree species diversity in the road space. Some areas in Depok City still have green areas, one of which is in the area of ​​street, park, and settlement in the Beji District. This study aims to compare tree diversity in the road space in the area of ​​street, park, and settlement in Beji District, Depok City. A sampling of trees was carried out by the belt transect method. Each tree encountered in the sampling plot is measured by DBH and identified to determine the composition and species richness of trees in each area, as well as to calculate the tree's Important Value Index (IVI), Shannon-Wiener diversity index, evenness index and Sorensen similarity index. In addition, data on environmental parameters such as temperature, humidity, and soil pH were also measured in the three areas to determine their respective environmental conditions. Based on the data obtained, it is known that Swietenia macrophylla is the most abundant tree species in the research location but is more concentrated in Swietenia macrophylla, Tectona grandis, and Pterocarpus indicus are the most dominant tree species, respectively, in the street, park, and settlement areas. The level of diversity in the street and settlement areas is in the medium category, while the park area is in the low category. Based on the calculation of the evenness index, the distribution of the number of individual tree species in settlement areas tends to be more even than in the areas of streets and parks. The street-settlement area pair has the highest degree of similarity based on the calculation of the Sorensen similarity index."
