The traffic problems have been increasing in recent few years. In many big cities, the volume of vehicle causes air pollutions and noises that are disturbing the comfortably of men activities. Highway is the most contributing factor in traffic problems. From many solutions, the greenery in highway is the one of sollutions against negative effects of traffic as environment buffer, especially for communities and for supporting users safety. The objectives of this study are to evaluate roadside greenery in Jagorawi High way as a buffer and for supporting of users safety in three major functions, there are air pollutants reduction, noises abatement, and space barrier. Fieldwork regarches were conducted onto three segments road: Bogor's - Ciawi's tollgates to Sentul’s ramp as lst segment (± 15,4 km length); Sentul's ramp to Cimanggis's ramp as 2nd segment (± 13,5 km length); and Cimanggis's ramp to Taman Mini's to gate as 3rd segment (± 15 km length). Every segment was divided into two seasions: East side and West side. The comparative method was used to measure subability and compatibility plants in roadside greenery in Jagorawi according to the regulations and principles of landscape architecture science. The comparative method result that all segments and sections on fieldwork indicate that plants selection, structures, patterns and configurations were not suitable and compatible enough for supporting the thee major functions of road greenery (assessment ranged from bad to moderate grades). The greenery at first segment achieves moderate grade (44,26% requirements fulfilled) in air pollutants reduction, bad to moderate grade (32,67% - 41,67% requirements fulfilled) in noises abatement, moderate grade (56,00% - 57,3394 requirements fulfilled) in space barrier function and moderate grade (56,00% - 58,17% requirements fulfilled) in aesthetic function. The second segment achieves moderate grade (47,54% - 50,32% requirements fulfilled) in air pollutants reduction, bad grade (30,0% requirements fulfilled) in noises abatement, moderate grade (57,69% - 58,85% requirements fulfilled) in space barrier function and moderate grade (57,50% - 58,46% requirements fulfilled) in aesthetic function. The third segment archieves moderate grade (49,35% - 50,74% requirements fulfilled) in air pollutants reduction, moderate to good grade (59,33% - 69'67% requirements fulfilled) in noises abatement, good grade (62,83% - 69'67% requirements fulfilled) in space barrier function and moderate grade (59,42% requirements fulfilled) in aesthetic function. According to the above analysis result, the study proposes a concept of appropriate plants selecting, according its structure and performance and so pattern and configuration to achieve the effectiveness of roadside greenery as environment buffer and supporting the safety in Jagorawi Highway.

Nira nipah (Nypa fruticans Wurmb.) memiliki manfaat unggul untuk diolah lebih lanjut menjadi bioetanol. Bioetanol yang dihasilkan nipah lebih banyak apabila dibandingkan dengan tanaman budidaya lainnya, seperti tebu, singkong, kelapa dan kentang. Potensi hasil ini sangat strategis, apabila dihubungkan dengan program nasional mengenai pengembangan energi baru dan terbarukan untuk mengatasi masalah kebutuhan energi yang semakin meningkat. Nipah mendominasi konfigurasi tumbuhan mangrove di sepanjang pantai utara pulau Sumatera, terutama di Sumatera Selatan. Sungsang, Sumatera Selatan, merupakan salah satu habitat dan ekosistem nipah yang penting. Penelitian ini dilakukan dengan tujuan menganalisis potensi produksi alami nira nipah yang mampu diolah lebih lanjut menjadi bioetanol. Hasil penelitian menunjukkan bahwa pada tahun 2013, potensi produksi alami nira nipah

Mount Seblat, as part a of Kerinci Seblat National Park (KSNP), is a pristine and natural mountain, particularly from disturbances and destructions by human activities. Nevertheless, the richness of biological resources especially plant diversity.in this area has not been more explored. The purpose of this study was to conduct an inventory of plant diversity and to determine the plant species composition. The inventory activities were conducted by plants collection along the ascent route. The results were then be maintained through ex situ conservation method in Cibodas Botanical Garden (CBG). The study was conducted by exploratory method, from Seblat Ulu Village (641 m asl) up to altitude of 1,037 m asl. There were 18 points of plant sample observation with an area of 5 x 5 square meters per point. Plant collection obtained 380 specimens. Five groups of most collected plants were Lauraceae (18 species), Rubiaceae (8 species), Anacardiaceae (6 species), Annonaceae (5 species), and Fagaceae (4 species). In order to enrich the plants collection as well as conduct the ex situ conservation effort, plants from Orchidaceae were also collected which resulted in 33 species. These results were an important initial inventory of plant diversity of Mount Seblat, considering that there was no record as well as very limited current information. When the environment disturbance tends to increase, this information may act as a reference and an initial database to develop plants conservation effort and strategy in the future.
