Judul: Gronophyllum and Gulubia (Palmae) in Sulawesi
Abstrak: Revision on Gronophyllum and Gulubia in Sulawesi has been done. This research is based on morphological characters of herbarium specimens from Herbarium Bogoriense, Bogor, and living plants from some areas forest in Sulawesi. The result shows that there are five species of GronophyNum and one species of Gulubia in Sulawesi. Four species of Gronophyllum are known previously namely: G. kjer'lbergii, G. microspndix, G. sarasinorum, and G. selebicum; one species is proposed as a new species, namely: G. macrospadix. The only one species of Gulubia is G. l~~ngrstaminSa.o utheast Sulawesi has three species of Gronophyllum and one Gulubia namely: G. kjellbergii, G. macrospadix, G. selebicum, and Gulubia longist~mina. South Sulawesi has two species of Gronophyllum and one Gulubia namely: G. kjellbergii, G. microspadix, and Gulubia longistamina. Center Sulawesi has only one species of Gronophyllum, namely: G. sarasinorum, and none of these species growing in North Sulawesi.

Judul: The fern diversity of South East Sulawesi
Abstrak: Floristic study has played an important role in expressing the diversity of plant species in a region. However such fern explorations are very rare, thus the data and information about ferns in Sulawesi Island particularly in South East Sulawesi is very limited. The objectives of this study is to know the diversity of fern species in South East Sulawesi region. The methods used in this study were exploration and description based on morphological characters. The study had been carried out in three locations, namely Mekongga Mountains, Uluiwoi and Wawonii Island. Materials used for this study comprised of herbarium specimens in the Herbarium Bogoriense and new specimens collected from exploration during this research in South East Sulawesi. This study documented 189 species belonging to 70 genera and 29 families. There are 173 species new collections of Pteridophyte from South East Sulawesi, 28 species of it are new from Sulawesi for Herbarium Bogoriense. Two species presumed as new species and 4 species are new records from Sulawesi. Fern in South East Sulawesi varied in their habit, rhizome, hair/scale, fronds and soral characters. Based on the habitat, there are nine types of ferns. Among three locations the greatest species diversity found in Mekongga Mountains (126 species), followed by Wawonii Island (87 species) and Uluiwoi (76 species). The degree of similarity of fern species at three different locations is low. Fern species are also used by local people for foods, medicine, ornamental plants, handycraft and construction. The identification key to the families, genera and species are provided.

Judul: Sistem Keamanan Parkir Berbasis RFID dan Standar Nirkabel IEEE 802.11b/g Menggunakan Raspberry Pi
Abstrak: Jumlah kendaraan bermotor meningkat setiap tahunnya dan juga tempat parkir. Area parkir dan pengelolaan yang tidak tepat dapat menyebabkan pencurian kendaraan bermotor. Penelitian ini mengusulkan suatu sistem manajemen keamanan parkir yang dapat membantu untuk mengurangi pencurian kendaraan bermotor. Sistem ini terdiri atas sebuah gerbang yang dikendalikan oleh komputer, radio frequency identification (RFID), dan aplikasi berbasis web yang terhubung ke tempat parkir melalui standar nirkabel IEEE 802.11b/g. Setiap pengendara harus memiliki kartu RFID untuk memasuki tempat parkir. Pengendara akan mendekatkan kartu pada RFID card reader dan sistem akan mencatat semua kegiatan. Sistem ini menggunakan Raspberry Pi Model B sebagai pengganti desktop komputer untuk mencatat dan memantau kegiatan pengendara. Hasil pengujian menunjukkan bahwa sistem dapat diandalkan dengan akurasi 100% dan waktu proses rata-rata 6.12 detik. Seluruh sistem dapat bekerja dengan baik dalam kondisi yang mungkin terjadi pada empat skenario pengujian, yaitu: pengujian pembacaan kartu RFID, pegujian posisi kartu RFID, pegujian waktu respon, dan pengujian akurasi/kehandalan.
