Abstract

The Anacardiaceae family holds significant ecological and economic value in tropical Asia, including Indonesia, as a source of fruits, timber, and valuable secondary metabolites. This study aimed to identify and describe the species diversity and morphological characteristics of Anacardiaceae in Percut Sei Tuan District, Deli Serdang Regency. The research was conducted from December 2025 to February 2026 using a descriptive exploratory method involving field observation, specimen collection, and morphological analysis. Sampling followed the exploration method of Rugayah et al., while morphological observations were based on de Vogel and Rifai. Species identification was conducted using taxonomic literature from the Anacardiaceae series of Flora Malesiana and herbarium specimens. The results recorded five species of Anacardiaceae: Mangifera indica, Mangifera odorata, Mangifera foetida, Anacardium occidentale, and Spondias dulcis. Mangifera indica was the most dominant species, comprising seven cultivated cultivars. Species differentiation was based on vegetative and generative morphological traits, including leaf type, shape, apex, texture, inflorescence type, fruit, and seed characteristics. The findings indicate relatively high diversity of Anacardiaceae in the study area, particularly within the genus Mangifera, influenced by environmental variation and human cultivation practices.

Abstract

Penelitian ini bertujuan untuk mengetahui keanekaragaman lichens pada tegakan pohon Kemiri (Aleurites moluccanus), Pohon Pinang (Areca cathecu) dan Pohon Kakao (Theobroma cacao) di Desa Kinangkong Kecamatan Laubaleng Kabupaten Karo, Sumatera Utara. Penelitian bersifat deskripstif dengan metode eksploraif dan inventarisasi pada tegakan pohon Kemiri (Aleurites moluccanus), pohon Pinang (Areca cathecu) dan pohon Kakao (Theobroma cacao). Teknik Purposive Sampling dengan menggunakan transek vertikal ke atas. Hasil penelitian menunjukkan bahwa pada pohon Kemiri (Aleurites moluccanus) ditemukan 11 jenis lichens dengan jumlah 91 spesies, pada pohon Pinang (Areca cathecu) ditemukan 10 jenis lichens dengan jumlah 51 spesies dan pada pohon Kakao (Theobroma cacao) ditemukan 9 jenis lichens dengan jumlah 54 spesies. Keanekaragaman lichens yang tinggi pada pohon Kemiri (Aleurites moluccanus) dengan indeks nilai penting (H′= 26,84) diikuti pada pohon Kakao (Theobroma cacao) dan pohon Pinang (Areca cathecu). Jumlah lichens dari ketiga pohon tersebut sebanyak 14 jenis dari 7 famili dengan 4 tipe talus (crustose, foliose, fructicose dan squamolose). Karakteristik habitat yang mendukung pertumbuhan dan perkembangan lichens pada lokasi penelitian berada pada suhu 27 0C – 29 0C, kelembaban 61% - 66%.
