People from East Nusa Tenggara generally use Gewang midribs for walls and ceilings. However this midribs contains ingredients that can be attacked by organisms such as termites. To overcome this, preservation action is needed. Conventional preservatives commonly contain ingredients that are less environmentally friendly, expensive and not easily available. Therefore it is necessary to find a natural preservative from the flora species more suitable for people. The purpose of this study was to obtain data and information about the effect of the concentration of natural preservatives from Tuba extract on the Gewang midribs. Tuba extract was obtained through the maceration using methanol. Preservation was carried out by soaking the Gewang midribs samples in to tuba extract solution with the consentration (gr/liter) of 0 (control), 4, 9, 16, 25 and 36 for 24 hours at room temperature. The effectiveness of preservatives was done using soil termites test. The results showed that tuba extract had a very significant effect on decreasing the weight of the sample and increasing the quality class of gewang midirb from class IV to II. It is recommended that preserving gewang midribs can use tuba extract with a concentration at least of 4 gr per liter of water

Pinus merkusii sap is one of Indonesia's superior NTFP products with high economic value. Increasing the sap productivity through the uses of geneticaly improved material of high resin yielder pinus, referred as “Pinus Bocor Getah” (PBG), is necessary. Vegetative propagation technique could used to obtain the high productivity of PBG in shorter times. This research aims to observe the rooting ability of PBG clones through a callus shoot cuttings technique. Of the 24 clones observed, 14 clones were taken from the hedge orchards and 10 clones were from selected tree in progeny test. Two experimental design used are completely randomized block designs and completely random design. Observation on the rooting ability includes parameters of the success rate of rooted, height increase, number and length of primary roots, number and length of secondary roots, root volume, root biomass and shoot and root ratio. The results showed that all tested clones showed ability to perform rooted shoot cutting, but the percentage rate of rooting varied among the clones. Amount of 71.42% clones from hedge orchard were rooted above 50% with Clone Pkp 9 and Pkp 13 as the highest percentage of rooting ( 93.75%). For the clones from progeny test, only one clone of Ppt 17 was rooted at above 50% (82.08%). The clones were significantly affected the primary root length and the number of secondary roots, especially for the clones from hedge orchard. The highest primary root length was found in Clone Pkp 3 (66.38 cm), and the highest number of secondary roots was found in Clone Pkp 14 (39). Other observed parameters were not significantly affeted by the difference of clones. The results of the study indicate that some PBG clones have the potential to be further developed massively through clonal propagation techniques.

Evaluation of the teak clone test aims to determine the growth and genetic parameters of the clones at the age of 20 years. Teak clone test was established in 1999 with a Randomized Complete Block Design (RCBD). The number of clones used was 65 clones, five replications (blocks), four treeplots, with a spacing of 3m x 3m. Measurements were carried out on the growth characteristics (i.e., plant height and diameter at breast height / DBH) and wood quality (i.e., Pilodyn penetration stress-wave velocity / SWV). The results of the analysis of variance showed that there were very significant differences in all observed growth characteristics. Heritability for plant height, stem diameter, Pilodyn penetration, and SWV were 0.38, 0.51, 0.59, 0.29, and 0.53, respectively. The expected genetic gains for volume and SWV were 21.81% and 2.11%, respectively, by selecting the best seven clones. The correlation between growth characteristics and between wood quality with growth characteristic is positive, indicating that improvement in productivity is followed by wood quality. The best clones based on clone values of stem diameter and SWV characteristics are clones number 110, 24, 97, 108, 20, 35, and 31, respectively.

Timoho (Kleinhovia hospita) wood is one of the raw materials for keris sheath that having high aesthetic and economic values. Due to exploitation of keris raw material that outmatches its planting activities, this type of tree is already hard to find in the Special Region of Yogyakarta, so this research aims to determine the generative propagation techniques carried out in the nursery of Center for Forest Biotechnology and Tree Improvement. Genetic material in the form of seeds in this study came from the parent trees grown in Bulaksumur region and Purwobinangun region, Yogyakarta. The methods that will be used are sampling, seed extraction, seed scarification in hot water for 24 hours, germination using wet tissue as media in petri dish, and planted in polybags. The result showed that viability of seeds from Bulaksumur region was 80% while that from Purwobinangun region was 68%. Observation and measurement of stem length and number of leaves every 2 weeks for 42 days showed that the number of timoho seed leaves from Purwobinangun had a higher number of leaves and a longer stem length, which is 19,11 ± 2,66 leaf blade and 11,54 ± 2,77 cm than the number of leaves and stem length from Bulaksumur, which is 0,59 ± 1,07 leaf blade and 7,59 ± 1,17 cm. Based on this research, it was concluded that although the viability of seeds from Bulaksumur was higher, the possibility of inbreeding from it broodstock caused the growth of seeds from Bulaksumur not as good as the growth of seeds from Purwobinangun

Biodiversity has a strategic role in socio-economic aspect, especially the provision services to humans and the surrounding ecosystem. Diverse of provision services encourage people to manage biodiversity in the cultivation environment, one of which is Kaliwu Agroforests. Kaliwu Agroforest, is a multi-species based of dryland farming model, developed by local communities in Sumba island to support various of provision services to the communiies, one of which is food. Recently, data and information about food crop species biodiversity in Kaliwu agroforests, and their contribution to meet the food needs to the local communities are not available. Understanding the biodiversity species of food crops in Agroforest Kaliwu and its contribution to household food needs is required. Therefore, field observations and interviews to 70 households of Kaliwu agroforest owners in Central Sumba District were carried out. Data and information obtained were analyzed descriptively and qualitatively. The results of analysis showed, the plants biodiversity of food source in Kaliwu Agroforests is varies. There are 12 species of food sources from the cassava group, and 46 species from the fruits group. Each farmer has different biodiversity of food crops species, and is determined by the choices and decisions of the farmers to cultivate. Farmers decision influenced the variations of tubers and fruits contribution in cultivate the Kaliwu agroforest. Contributions of foodstuffs per capita needs of tubers ranges from 35-41%, while for the group of fruits range from 55-81%. Referring to the species variety and its contribution value, Kaliwu Agroforest has a significant role to support the biodiversity conservation and fulfilment the food needs to the local communities. It is needed to encourage and empower the local potential agroforests an alternative to build community-based food security, such as Kaliwu Agroforest that provide added value, and increase food self-sufficiency and security in the local communities

The potential of bamboo as a plant for soil and water conservation can be identified by the morphological character. The quality of bamboo can be shown from the morphological character. Bamboo is a plant that is difficult to propagate generatively, while there is a paucity information on the vegetative propagation of bamboo species especially genus of Gigantochloa and Schizostachyum. The aims of this research is to characterize morphology of bamboo, studies of bamboo propagation with vegetative method and measure the potential of bamboo as a plant for soil and water conservation. 4 species of bamboo namely Gigantochloa atroviolaceae Widjaja, G. robusta Kurz., G. luteostriata Widjaja and Schizostachyum zollingeri Steud.are used in this study. The result of morphology characterization show that four species of bamboo have unique morphological characteristics from reed midribs, reed height, diameter, leaves and roots. The results of vegetative propagation of bamboo using different growing media show that the compost + soil (1: 1) is the best for bamboo growth. Soil media can also be used as an alternative media for vegetative propagation. Sand mediagives the lowest growth. G. atroviolaceae and G. robusta are species of bamboo that suitable for soil and water conservation. Both species of bamboo are characterized by strong reed, dense growth and canopy, good quality of litter, and a strong root system that supports to soil and water conservation.

Ganoderma root disease in the community forest of sengon is one of the limiting factor to increase the productivity of sengon wood. This disease has been reported in West Java, East Java, South Sumatra and South Kalimantan. The survey was conducted to determine the existence of Ganoderma root disease in three sengon fields in Sleman, Yogyakarta. The existence of Ganoderma root disease was recognized based on the symptoms of diseased plants and the present of Ganoderma basidiocarp on the diseased sengon stem. The survey results on three sengon fields was succeed in finding diseased plants and also the basidiocarp of Ganoderma on the basal of the diseased plant stem. Symptoms that have been found was either dead or dying trees (few leaves left). The basidiocarp of Ganoderma on the diseased plants varies in characteristic while its young and mature. The basidiospores is ellipsoid, truncate, rough (coarsely echinulated), and double-walled. The Ganoderma colony was white and turned to yellow orange from the center. Based on this study the Ganoderma root disease in sengon plants has developed in Sleman, Yogyakarta. The presence of dead or dying trees with few leaves left between healthy sengon trees and the presence of Ganoderma basidiocarp in diseased trees are indicator of the presence of root disease in the sengon field caused by Ganoderma.
