The Campus of Sriwijaya University in Indralaya , has a high diversity of flora including fern, especially the epiphytic ferns, whose existence is so widely found in oil palm plants. This epiphytic study has been conducted from July to November 2017, with the aim of identifying the diversity of species of epiphytic ferns in oil palm plants on the campus of UNSRI Indralaya. The research method used is exploration method with direct collection technique from the field and then made herbarium. In this study found 27 species, which belong to 7 families, namely Aspleniaceae, Blechnaceae, Davalliaceae, Lygodiaceae, Nephrolepidaceae, Polypodiaceae, and Vittariaceae. The most common types are Polypodiaceae family Drynaria quercifolia, Drynaria sparsisora, Microsorum pustulatum, Microsorum punctatum, Phymatosorus scolopendria, Polypodium verrucosum, Polypodium polysthicum, Pyrrosia piloselloides, and Goniophlebium verrucossum. The most widely distributed species in oil palm is Davallia denticulata , Goniophlebium verrucosum, and Nephrolepis biserrata.

Abstract. Sarno, Suwignyo RA, Dahlan Z, Munandar, Ridho MR, Aminasih N, Harmida, Armanto ME, Wildayana E. 2017. Short Communication: The phenology of Sonneratia alba J. Smith in Berbak and Sembilang National Park, South Sumatra,. The ecosystem of mangrove forms the largest portion of the habitat in Berbak and Sembilang National Park (BSNP), Banyuasin District, South Sumatra Province, Indonesia, which is the largest mangrove area in the western part of Indonesia. There is a tendency that the mangrove condition in this area is gradually degrading over time. The main causes of mangrove destructions are both natural and human factors. The destructions of mangrove in BSNP directed by human are more than natural factors, for axample, land use conversion from wildland into cultivated land, the making of ponds, especially along Banyuasin Peninsula. The information on the observation of mangrove phenology is very important for sustainable mangrove management. The observation of mangrove phenology in the restoration area of BSNP is intended to study the natural stages of growth and reproductive development of Sonneratia alba J. Smith, the local name is Padada. The observation is done by means of tagging methods. Monitoring is conducted periodically from the flowering time until the fruit was ripe. The phenology of Sonneratia alba takes about three months from the beginning of flowering until the fruit was ripe.

Mangrove conditions in the region under pressure and degradation from year to year. The main cause of mangrove destruction in the Sembilang National Park (SNP) is cultivation or manufacture of fish ponds, especially in the Peninsula Banyuasin South Sumatra. The activities of these ponds have resulted in the degradation of mangrove, especially in greenbelt. The destruction of mangrove areas causes a decrease in the quality and extent of mangrove areas which result in the degradation of a variety of important functions. Damage to mangroves occur both at the regional, national and even up to the global level. The purpose of this study is to know the process of natural mangrove revegetation on former ponds. The composition of the type of vegetation that grows in the area of the former ponds in South Sumatra region SNP restoration consists of four species: Avicennia marina (Forssk.) Vierh., Avicennia alba Blume, Rhizophora mucronata Lam., and Portulaca villosa. The most dominant species of mangrove revegetation of former pond in SNP is A. marina.

Penggunaan  tumbuhan berkhasiat obat telah dikenal sejak lama oleh Suku Ogan di Desa Beringin Dalam kabupaten Ogan Ilir, sudah diwariskan turun temurun dari generasi ke generasi, tetapi dengan berkembangnya zaman, penggunaan tumbuhan obat oleh Suku Ogan sudah mulai berkurang, sehingga penting untuk menggali kembali pengetahuan mengenai tumbuhan berkhasiat obat untuk mempertahankan warisan nenek moyang Suku Ogan. Penelitian ini bertujuan  mengidentifikasi jenis tumbuhan obat, bagaimana cara pengolahan  dan cara penggunaannya oleh Suku Ogan di Desa Beringin Dalam., yang  Penelitian dilakukan Februari - Mei 2021, bertempat di Desa Beringin Dalam Kecamatan Rambang Kuang Kabupaten Ogan Ilir Sumatera Selatan. Metoda yang digunakan adalah  wawancara secara langsung pada sumber informan yaitu dukun dan pemangku adat Suku Ogan di Desa Beringin Dalam. Hasil penelitian menunjukkan masyarakat suku Ogan menggunakan 65 jenis dari 35 famili sebagai bahan oba, yang didominasi oleh kelompok Euphorbiaceae yaitu 6 spesies. Habitus tumbuhan didominasi pohon sebanyak  23 jenis tumbuhan. Bagian tumbuhan yang banyak digunakan ialah daun yaitu  22 spesies. Sumber perolehan tumbuhan obat banyak diperoleh dari budidaya yaitu sebanyak 38 spesies. Cara pengolahan dan penggunaan tumbuhan obat banyak dilakukan dengan cara direbus dan diminum yaitu sebanyak 36 spesies dan 39 spesies.
