TL;DR: Indonesia is not only rich in its biodiversity but it is also well known as a country with high diversity of ethnicities as discussed by the authors, and each ethnic group has extensive experienced in the utilization and conservation of biological and ecological diversity.
Abstract: Indonesia is not only rich in its biodiversity but it is also well known as a country with high diversity of ethnicities. Each ethnic group has extensive experienced in the utilization and conservation of biological and ecological diversity. This biocultural richness has provided ethnobotanical researchers with endless research opportunities. Ethnobotanical study has a long history in Indonesia and dates back to the early Dutch colonization period when Dutch explorers and naturalists recorded the uses of plants used by the natives for food, medicine, buildings materials, etc. Based on research on Java, Hasskarl (1845) recorded 900 species of plants used by Indonesian communities. Previously, Rumphius (1750) in his monumental book "Herbarium Amboinense", reported the uses of several hundreds plants from Ambon and its vicinity. Recently, Indonesian scientists from both government and non-government organizations have given more attention to the importance of ethnobotany as a means of elaborating traditional knowledge, especially for economically useful and scientifically undiscovered plants. The talk will focus on ethnobotanical research performed by LIPI scientists at the Research Center for Biology in Bogor and the Indonesia Botanic Gardens. During the last 20 years, since the Indonesia' Ethnobotanical Museum was established. Indonesian scientists have documented the importance of ethnobotany, ethnomedicine, ethnomycology, ethnoentomology, and ethnoecology for conservation of traditional knowledge in relation to the economic botany and to other applied sciences. The meaning and scope of ethnobotany and its status including the future prospects, its contribution to the exploitation and conservation will be discuses in this paper.© 2008 Jurusan Biologi FMIPA UNS SurakartaKey words: ethnobotany, ethnomedicine, ethnomycology, ethnoecology, traditional knowledge, use of plants, Indonesia.

TL;DR: In this article, the authors investigated intensive rotational grazing by dugongs in intertidal inshore Halodule univervis seagrass meadows, and analyses of parameters explaining the temporal and spatial patterns of grazing in these meadows.
Abstract: Research on dugong-seagrass interactions in Indonesia was done during the period 1990 until 2005 in respectively East Aru, Maluku Province and East Kalimantan, Indonesia. This research investigated intensive rotational grazing by dugongs in intertidal inshore Halodule univervis seagrass meadows, dugong movements in relation to these grazing swards, and analyses of parameters explaining the temporal and spatial patterns of grazing in these meadows. In this paper, we report the findings of this long-term study. The patterns of movement and the results of snorkelling surveys confirmed a practice of regular recropping of restricted grazing swards by small feeding assemblages of dugongs. Dugong grazing showed a significant correlation with carbohydrate content of the below-ground biomass and no significant relation with total N. The timing of dugong grazing in these intertidal meadows coincides with high below-ground biomass and high carbohydrate content in the rhizomes of H. uninervis in the upper 0-4 cm sediment layer. Our findings support the hypothesis that temporal dugong grazing is ruled by carbohydrate content in below-ground biomass. The mechanisms of rotational grazing in restricted grazing swards are not yet well understood, and the maximisation of carbohydrates does not fully explain this phenomenon. Our research confirms that intertidal H. univervis seagrass meadows form a crucial resource for dugong survival. These relatively unknown biotopes need therefore more attention in research and conservation programmes.

27 Sep 2017TL;DR: In this paper, the authors reviewed literatures on potential and characteristics of lignocellulosic materials, especially sugarcane bagasse, and conversion of these materials to ethanol.
Abstract: Utilization of lignocellulosic biomass from sugarcane bagasse for bioethanol production Sugarcane bagasse is one of potential lignocellulosic biomass for energy through physical, chemical or biological conversion. The material is renewable and abundantly available, especially as wastes or by-products of sugarcane industries. Of many conversion processes, lignocellulosic conversion to ethanol becomes focus of interest recently, since ethanol can be further used as biofuel to substitute gasoline for transportation. Lignocellulosic material, including sugarcane bagasse mainly consists of three components, namely cellulose, hemicellulose, and lignin. The conversion of these materials basically consists of pretreatment, cellulose hydrolysis, sugar fermentation to ethanol, and purification of ethanol. Production cost of this conversion is still high; therefore, many researches have been conducted to improve the conversion process, either pretreatment, hydrolysis, fermentation or purification, so that the cost could be reduced. This paper reviewed literatures on potential and characteristics of lignocellulosic materials, especially sugarcane bagasse, and conversion of these materials to ethanol. There is as much as 614,827 kL/year of ethanol potentially produced from sugarcane bagasse resulted from sugarcane factories in Indonesia. This amount of ethanol would have a great contribution to fulfill 1.10 million tons demand of ethanol. However, there are still some recalcitrans in production and implementation of lignocellulosic bioethanol, especially due to the unproven conversion technology of lignocellulosic biomass to ethanol and the high production cost. Therefore, government policies in supporting research and development, providing special incentives for sugarcane factories that produced ethanol from sugarcane bagasse, and giving subsidy to reduce bioethanol price, are needed.

TL;DR: In this paper, the authors investigated 44 Indonesian plants belonging to 24 families for tyrosinase inhibitory activity and isolated chlorophorin as one of the active compounds in the sapwood of Artocarpus heterophyllus.
Abstract: In our efforts to find new tyrosinase inhibitory materials, we investigated 44 Indonesian plants belonging to 24 families for tyrosinase inhibitory activity. The extracts of 5 Artocarpus woods showed potent tyrosinase inhibitory activity (over 80% at 100 µg/ml) similar to a positive control, kojic acid. In Artocarpus woods, the extracts of the sapwoods showed stronger inhibitory activity than those of the heartwoods. Chlorophorin was isolated as one of the active compounds in the sapwood of Artocarpus heterophyllus. The content of chlorophorin in sapwood was higher than that in heartwood.
