Abstract

The aliphatic fraction is usually the largest component in crude oil. Its removal from oil contaminated fields has become an environmental priority and been considered useful for enhancing recovery. Our previous studies reported the isolation of Fusarium sp. F092 based on the ability to degrade chrysene. It also could degrade crude oils and their aliphatics fractions. However, aliphatic degradative pathways in crude oil have not been clearly understood. The identification of aliphatic metabolite pathways using a representative compound n-octadecane was carried out in this study, as well as the effect of Piperonyl Butoxide (PB) and Silver Nitrate (AgNO3) on the degradation of n-octadecane and its metabolite. We determined that Fusarium sp. F092 had ability to break down n-Octadecane from about 125 to 13 mg L-1 after 60 days incubation. During degradation, several metabolite products could be detected and identified to form carboxylic acid groups. By the addition of PB and AgNO3, inhibitor of monooxgenase and dioxygenase enzymes, Fusarium sp. F092 had ability to convert n-octadecane to form alkyl hydroperoxides via terminal oxidation pathway with involving a dioxygenase

Abstract

Parent gametes contribution is one of the important factors that affect on differences of morphologies/ phenotypic of individual tree in a seed orchard. Morphological variations plus trees observed in an opened pollination seed orchard of A. mangium. Parent trees that produce good performance offspring should be identified to increase the efficiency of tree improvement strategies of this species. Thus, aims in this study were to assess mating system and to identify parental trees within a single population first generation SSO that resulted good growth character in a multi location trial of A. mangium. This study was conducted in two types of seed orchard i.e. a single population (SP) F1 and a multi location trial (MLT) plot E of A. mangium at Wonogiri (Central Java). Using ten microsatellite markers for A. mangium, parental analysis was conducted with comparing genetically between plus trees in the SP as a parent trees and thirty two the best rank plus trees in MLT as an offspring and analyzed using program Cervus ver.3.03. Results showed that the plus trees in the MLT orchard originated from various parent gametes contribution in the SP seed orchard. Moreover, the best rank plus trees dominantly originated from single pair between maternal and paternal trees. However, another pollination behavior, a maternal tree was pollinated by two paternal trees. Moreover, a paternal tree pollinated several maternal trees. Similar flowering characteristic of individual trees that originated from same provenance might be responsible to the pattern of mating system in the opened pollination seed orchard. From the results, efficiency on seed orchard management might be proposed.

Abstract

Tree improvement program for Eucalyptus pellita in Center for Forest Biotechnology and Tree Improvement (CFBTI) was started in 1994. The programs are now beginning their third-generation of breeding which have relied on recurrent selection through establishing open-pollinated seedling seed orchard. Using current technologies, several Industrial Forest Companies in Indonesia are pursuing clonal forestry program with E. pellita to increase plantation productivity using selected clones from comprehensively field testing. This study was aimed to evaluate the early growth and stand volume productivity of selected clones of E. pellita as a part of a breeding program for pulpwood conducted by CFBTI.  Two clonal trials of E. pellita were established in Central Java with two different plot configurations: single tree-plot and multiple tree-plot. Measurement at the trials was done at two years age involving tree height, diameter, stem volume and stand volume. The results of study showed that among the clones were significantly different for all traits accessed. All of tested clones exceeded the control seedling of F-1 generation by 9-50% for height, 10-36% for diameter and 22-137%  for stem volume. Clone repeatability ranged from 0.7-0.9, with corresponding individual ramet repeatability ranged from 0.2-0.4. The outperformed of the best three selected clones in single tree-plot trial was consistent when planted in multiple tree-plot trial with stand volume productivity at given age reached 15 m3/ha.

Abstract

A compatible volume estimation model for Acacia mangium Willd. was developed from data corresponding to 279 felled sample trees collected from the A. Mangium plantations in South Sumatra, Indonesia. The model comprises a total volume model and a stem taper model, which is compatible in the sense of the total volume obtained by integration of the taper model being equal to that computed by the total volume model. Several well-known total volume functions were evaluated. A logarithmic model was determined to be best and was then used as the basis for deriving the taper model. Appropriate statistical procedures were used in model fitting to account for the problems of heteroscedasticity and autocorrelation that are associated with the construction of volume and taper functions. The developed model can be used to estimate total stem volume, merchantable volume to any merchantability limit, diameter of any height, and (possibly) height of any diameter based on only easily measurable parameters such as diameter at breast height and total tree height for the species analysed. The models provide a major improvement over the previous models for A. mangium plantations in Indonesia which were only applicable for estimating stem volume to a fixed top diameter limit.

Abstract

The utilization of unproductive aren (Arenga pinnata) for timber produces waste i.e. sawdust and core. The waste containing of lignocellulosic materials was studied for cultivation medium of edible mushroom. The sawdust was supplemented with rice bran, CaCO3, gypsum, fertilizers, and distilled water. This composite medium was then sterilized in an autoclave on 121 ⁰C, in pressure of 1.5 atmosfir for 30 minutes. After cooling the medium was inoculated with pure culture of four different mushrooms species and incubated in a special room. Biological conversion efficiency (BE) was calculated based on the weight of the fresh mushroom yield to the weight of dry substrate and presented in percentage. Other waste in the form of sawn timber core was cut into 10 cm in wide 5 cm in thick and 120 cm in length, then directly inoculated with six species of mushrooms through drilled holes, then were slanted on bamboo supporter in an angle of around 60⁰ in a hut made of bamboo. The mushroom’s was harvested daily after the mature fruiting body grown. Results showed that the material supplementation on sawdust most likely to improve the mushrooms yield. Found that the BE values are 21.97-89.45 % (for Pleurotus flabellatus), 15.36-105.36 % (for P. ostreatus), 63.88-76.86 % (for P. sajor-caju), and up to 62.88% (for Lentinula edodes). The average yield from a piece of sawn timber core was 210g (for P. ostreatus), 368g (P. flabellatus), 331g (P. sajor-caju), and 48g (Auricularia polytricha), however, P. cystidiosus and L. edodes on aren stem core were fail to grow.

Abstract

Without good control, fuel-wood extraction from conservation forest, such as Way Kambas National Park (WKNP), can threat the existence of the forest. This paper observes the way to tackle the forest degradation in WKNP, with minimum impacts to the local people who use the fuel-wood. The study includes analysing the appropriate policy for using the fuel wood. Observation was carried out by analysing existing data and maps of WKNP in various perspectives: forest degradation, inventories, analysis of current policies, survey on how fuel-wood is extracted, mapping the mobilisation of fuel-wood gatherers, survey on fuel-wood demand, and identification of further policy options. The results show that there is fuel-wood extraction activity in WKNP influenced by income level, land ownership, the number of household members, the distance to forest area, and the age of patriarch. However, this activity is tolerated by unwritten policy at local level, although this is forbidden by written policy at national level, so this creates the failure in maintaining sustainable off-take of fuel-wood. This is supported by the fact that fuel-wood extraction in WKNP triggers the reduction of forest stock and the changes of species diversity, species evenness, and old-young tree ratio due to destructive techniques used such as slashing, scratching cambium, and cutting trees. Therefore, some recommended policy options are legalizing fuel-wood extraction with limitations, providing alternative fuel-wood and other biomass energy resources outside WKNP, running preventive and pre-emptive measures, cooperating with other stakeholders, and empowering local economic
