TL;DR: There were 10 bamboo species in Sumba Island, 1 species was a new species which has not been collected before, whereas the other species has a new addition record from this area, and the genus Dinochloa was the only genus grow climbing.
Abstract: Bamboo is one of the economic plant which grow widely in the villages and have been used by the local people in the villages. Indonesia has about 10% of the world bamboo, 50% among them was endemic to Indonesia. According Widjaja (2001) Lesser Sunda Island which consists of Lombok, Sumbawa, Flores, Timor, Sumba and other small island eastern of Flores has 14 bamboo species, however, the information from the Sumba Island was lacking because of lacking data from this area except one species which was proposed by S. Soenarko in 1977 where the type specimens was collected by Iboet 443 in 1925. To fullfill data from the Sumba Island, an exploration tothis area has been conducted on July 2003. The observation was done in West Sumba and East Sumba District, especially in two natioal parks at both districts. According to this inventory study in the Sumba Island, there were 10 bamboo species in Sumba Island, 1 species among them (Dinochloa sp.) was a new species which has not been collected before, whereas the other species (Dinochloa kostermansiana) has a new addition record from this area. The bamboo species in Sumba Island were Bambusa blumeana, Bambusa vulgaris, Dendocalamus asper, Dinochloa kostermansiana, Dinochloa sp., Gigantochloa atter, Nastus reholtumianus, Phyllostachys aurea, Schisotachyum brachycladum and Schizostachyum lima. From 10 recorded species, the genera Dinochloa and Nastus grow wild in the forest, whereas another species grow widly or cultivated in the garden. Furthermore, the genus Dinochloa was the only genus grow climbing. The endemic species found in Sumba Island was Nastus reholttumianus, whereas Dinochloa kostermansiana was also found in Flores Island.© 2005 Jurusan Biologi FMIPA UNS SurakartaKeywords: biodiversity, bamboo, Sumba Island.

TL;DR: In this article, a study was conducted by exploring the bamboo in the buffer zone as long as 6.000 m, the width of the two paths on both sides of the Kedome river was 50 m each.
Abstract: Most bamboo has a tight sympodial rhizome root system that can be used for conservation of river border. Generally, bamboo in each watershed has a variation, such as in Tiupupus watershed North Lombok District, there were found 4 bamboo genera, 9 species, and 1 variety while in Meniting watershed, West Lombok District, there were found 6 genera of 8 species of bamboo. This study aims to determine species of bamboo and its distribution along buffer zones of the Kedome river in East Lombok District. Sampling method was conducted by exploring the bamboo in the buffer zone as long as 6.000 m, the width of the two paths on both sides of the river was 50 m each. Data were analyzed using description method. The results showed: there were 3 bamboo genera, 5 species and 1 variety e.g. Gigantochloa apus, Gigantochloa atter, Thyrsostachis siamensis, Bambusa maculata, Bambusa vulgaris, and Bambusa vulgaris var. vittata. Species of Gigantochloa atter and Bambusa vulgaris have tight sympodial rhizome roots, rounded and thick canopy. Both types of bamboo are recommended to be used as soil and water conservation plants in the watershed.

TL;DR: In this article, the raw material characteristics of thorny bamboos from two different origins were examined for their growth, chemical contents, fiber dimension, and dissolving pulp characteristics, and the results showed alpha-cellulose of the thorny bamboo from Agam (TB1) and Perawang (TB2) were 51.28% and 36.90% respectively, while the fiber of TB2 was longer than that of TB1 that 3.22 and 2.62 mm.
Abstract: This study was aimed to examine the raw material characteristics of thorny bamboo (Bambusa blumeana) from two different origins. Thorny bamboo is one of the raw material for dissolving pulp (rayon pulp). The origins of the bamboos were Agam Regency (West Sumatra Province) (TB1) and Perawang City of Siak Regency (Riau Province) (TB2) that represented highland and lowland, respectively. Bamboos from the two origins were analyzed for their raw material characteristics consisted of growth, chemical contents, fiber dimension and dissolving pulp. The pulping process was carried out in steps as followed: prehydrolyzed, kraft pulping and pulp bleaching. The pre-hydrolysis techniques used acetic acid solution. The kraft condition was active alkali 25% and sulfidity 32%. Meanwhile, the bleaching was conducted in 4 stages. The analysis was done descriptively. Dissolving pulp requires high purity level of alpha-cellulose that would be attained by dissolving other components from the system. The results showed alpha-cellulose of thorny bamboo from Agam (TB1) and Perawang (TB2) were 51.28% and 36.90%, respectively. However, the fiber of TB2 was longer than that of TB1 that 3.22 and 2.62 mm, respectively. The yields pulp kraft of thorny bamboo TB1 and TB2 were 35.25% and 36.28%, respectively. The alpha-cellulose of the thorny bamboo met the standard for dissolving pulp but not the mineral and acid insoluble ash content.
