Abstract

The aim of this study were to identify and evaluate a condition in logged over area (LOA) after 5 years of reduced impact logging (RIL) implementation, and to asses how far recovery of former skidding road, damages in felled and yarded over area, and environmental condition had taken place. Results of this study was expected to provide inputs and to improve the RIL implementation guidance for sending   sustainable forest management. The results revealed that: (1)The covers of skidding road reached consecutively 2,641 m2  area (in block I), and 3,147 m2  area (in block II), as both marked by the growing of  bushes with coverage portions i.e. 84% and 80%, respectively; (2) The bush that grew on the former skidding road was regarded as pioneer vegetation; (3) The effect of cross drain on skidding road after logging was able to decrease erosion, and increase the recovery of the road condition; and (4) The healthy residual stand after 5 years logging by RIL showed that small diameter felled trees have resulted bigger residual stand damaged then big diameter or the percentage of healthy trees would be small.

Abstract

Various experimental testing procedures were undertaken in Indonesia to determine the effectiveness of a patented superficial (envelope) treatment using bifenthrin to protect radiata pine framing material from damage by two species of subterranean termites (Macrotermes gilvus and Coptotermes curvignathus) and one species of drywood termite (Cryptotermes cynocephalus). Lengths of framing material (Pinus radiata sapwood) were commercially treated to the targeted retention of 0.02% m/m of bifenthrin in the outer 2 mm depth penetration zone of the material. The treated and untreated materials were subsequently cut into test specimens and exposed to M. gilvus in the field and a semi-laboratory trial, to C. curvignathus in the laboratory and a semi-laboratory trial and to C. cynocephalus in a laboratory trial. No supplementary treatment was performed on the exposed cut ends of the treated test specimens. The results from the trials clearly demonstrated that the superficial treatment of bifenthrin seemed effective in protecting test specimens of radiata pine framing material from significant damage by Indonesia’s most notorious termite species that often causes serious economic loss to the timbers. Termites were unable to damage any of the bifenthrin-treated surfaces of test specimens. Any obser ved damage by termites, albeit minor, was in all cases confined to the exposed cut ends of test specimens. In contrast, attack by termites on the untreated control test specimens caused damage of the samples ranging from light to heavy.

Abstract

Fellingis an early step in timber utilization process. Efficiencyand effectivity of felling technique, tool type and feller posture will affect the whole timber utilization efficiency. This study was carried out at two timber estates in East Kalimantan and intended to see the effect of two felling techniques and feller postures on felling productivity, fellingcost, as well as timber utilization efficiency.Primary  data collected in this research  included :  felling time, volume  of  felled timber, productivity, felling efficiency, stump height and felling cost. The data was analyzed using split-plot design with factorial pattern.The result showed that the implementation of lowest possible felling technique (LPFI) increased log production from 14.4  to 17.7%. The lowest stump height left was of  the one using LPFf  with particular bowed posture in PT. Sumalindo Lestari Jaya I (SLJ I) (4.82 cm).

Abstract

Biological diversity can have significant contribution to reduce the build-up of greenhouse gases in the atmosphere. The trees in a forest stand form an essential part in the functioning of the terrestrial biosphere, especially in the carbon cycle. Yet tree photosynthesis is far less studied than crop photosynthesis for several reasons: the large number of species; difficulty in measuring photosynthesis of entire trees or of forest stands. This research aims to assess the contribution of biological diversity in carbon sequestration by analyzing the physiological characteristics (photosynthesis, transpiration, stomatal conductance, leaf chlorophyll content) of species native to tropical highland forest ecosystem of Mount Halimun-Salak National Park. The results showed that there was a wide range of variation of CO2 assimilation rate between tree species. The overall CO2 absorption rate ranged 1.1913 - 31.3875 µmolm-2 s-1, the highest rate was reached by Lithocarpus sp. (pasang parengpeng) (31.3875 µmolm-2 s-1)followed by Litsea noronhae(huru lumlum) (21.5750 µmolm-2 s-1), Saurauia nudiflora (kilebo) (11.8175 µmolm-2 s-1), Vernonia arborea (hamirung) (6.7125 µmolm-2 s-1) and Litsea.sp. (huru bodas) (6.2725 µmolm2 s-1). The rate of CO assimilation was affected by incident radiation and thus the photon flux (Q leaf). Correlation between CO assimilation and Q leaf under certain environmental condition was considerably high. Incident radiation and Q leaf also affected stomatal conductance and thus rate of transpiration.

Abstract

Sappan wood or kayu secang (Caesalpinia sappan L.) was reported of having medicinal uses,  such as  for natural antioxidant, relieve vomiting of blood, and ingredients mix for malaria drugs.  The research was conducted to study the influence of ethanol extract from sappan wood on blood glucose level of white rats. The blood glucose level in rats was carried out by using glucose tolerance method. It was measured by Reflolux S (Accutrend GC) and Chloropropamide 50 mg/200 g BW (Body Weight) as positive control. The ethanol extracts were used in various concentration 10, 20, 30, 40 and 50 mg/200 g BW per-oral and observed every an hour and beginning one hour before to 7 hours after the extract being administered. The results showed that the administered dose 30 mg/200 g BW of the ethanol extracts equal the positive control. Statistical analysis gave significant differential (P<0,05) in 2 and 3 hour after treatment.

Abstract

A study on demography,  growth  and survival of  seedlings and saplings was conducted  in the Hutan Kintap  concenssion,   South Kalimantan,   Indonesia. The aim of  the study  was to monitor  pattern  of growth of seedlings and saplings among different types of logged -  over forest, including the newly  logged  -  forest, older  logged  -  over forests   (treated and untreated),   and un-logged-forest    patches.   The  study began in 1991, and nineteen  of  0.25  ha plots   were set up in a total  of  six blocks  designated   as consecutively  A, B, C, D, E and F.  Block A was a newly logged   forest and had five plots,  and Block  B -  D were in forest which  had been logged  in 1979.  Block B (five plots) had received no silvicultural   treatment,  while Block  C (five plots) and  D (one plot)   had  been  lightly   thinned  after  felling and  further  Block C received  a further  thinning treatment   Block  E (one plot)  had been  heavily   thinned,  and Block F (2 plots)   was an un-logged   control. The  density  of  seedling  varied within  the study sites, and averaged  from  47,000 ha"  to 121,000   ha·1•   The mean height increment  of  seedlings varied among block ranging from 2.9  cm year  to 10.5  cm year".  Block A had the highest general  mean  increment  of  10.5  cm year",   followed  in decreasing  order  by Block C of 5.4 and Block F, 4.5  cm year".  Growth  of  seedling in Block  B was low, even lower  than  the growth  in the un-logged   Block F. The  difference  of the increment among Block A, B, C and F however was not significant. The liberation treatment  in Block C significantly   resulted in a higher (p<0.01)  increment  (5.4 cm year") than that in  the untreated  Block  B (2.9 cm year").  Seedling  mortality ranged from 16 to 37 % year", and declined with  height   class. The  mortality  of  seedlings  might  be related  among  other  factors  to the  humidity  and density  of  seedlings per-unit  area. The  density  of  sapling ranged  from 6,800 ha" to 7,700  ha" and they had diameter  growth  of  0.8 mm  year" to  2.2  mm year",  and height   growth  of  12.6  cm year" to 21.8  cm year"1. The  difference  in the  diameter  increment   among  block  r, B,  C and  F was  not  significant.    The  average sapling height increment  varied (but not significantly so) among Block,  ranging from 12.6  cm year" in Block A to 21.8  cm year" in Block C. Mortality  of  sapling was relatively   low  in all block.  Higher  mortality  in the un-logged   forest  Block  I and  in the untreated  Block B might  due to  the low  degree  of  canopy   opening.

Abstract

Rhizoctonia solani is a soil pathogen that causes diseases in wide range of hosts of agricultural, horticultural and flower crops. Biological control is the most promising way for the diseases management and it is environment friendly too. The objective of this study was to isolate and screen the potency of soil bacteria as biological control from various local compost and peat soil of tropical peat swamp forest in Kalampangan Zone, Central Kalimantan. Forty seven isolates from peat soil and compost were screened for biocontrol agent of Rhizoctonia solani . R. Solani Seven out of thirteen peat soil isolates, and six out of thirty three compost isolates showed antagonistic activity against in Potato Dextrose Agar. The cultivation of the antagonistic isolates in Trypticase Soy Broth (TSB) was extracted and analysed by high performance liquid chromatography (HPLC) column. The HPLC analyzes indicated that the antagonistic isolates produce an antifungal iturin A. Macroscopic observation of isolates colonies showed that form of their colonies were amuboid, myceloid, curled, circular, rhizoid, irregular and filamentous. These achievement indicate peat swamp forest not only offer a potential biocontrol agents of damping off but also provide a new source for production of antibiotics.

Abstract

This study was subjected to observe the possibility of  introducing specific foreign genes into Melia azedarach L., using Agrobacterium mediated transformation. Agrobacterium tumefaciens used in this study consisted of  strains of  EHA105 (vector plasmid pBIsGFP) and EHA105 (vector plasmid pBsGFP) to observe the possibility of introducing genes, and strains of EHA101 (vector plasmid pIG121-Hm) and LBA4404/ferritin (vector plasmid pBG-1) to observe the shoot organogenesis after genes transformation. Explants were collected from one cm in length excised stem of in-vitro plantlets. The results of the study showed that genetic transformations of M. azedarach could be potentially developed using Agrobacterium tumefaciens strains : EHA105 (pBIsGFP or pBsGFP), EHA101 (pGI121-Hm) and LBA4404/ferritin (pBG-1). The expression of  GFP (green fluorescence protein) signal worked successfully in this transformation  with 40% of transformation  rate for pBIsGFP and 20 % for pBsGFP.  The application of Agrobacterium strains of EHA101 (pIG121-Hm) and LBA4404/ferritin (pBG-1) which contained specific gene of kanamycin resistance and iron accumulation for plant growth improvement showed that adventitious shoot was well induced and elongated on the rate of 30 - 60 % of explants after genes transformation.

Abstract

Previous research on anatomical structures of pretreated large (betung) bamboo (Dendrocalamusasper) using single culture of white-rot fungi has been investigated, which revealed that the pretreatment caused the decrease in the Runkel ratioas well as the coefficient rigidity and the increase in the flexibility ratio of their corresponding bamboo fibers. However, there is no study reported on the anatomical structure changes of them caused by pretreatment using mixed culture of white-rot fungi. This paper reports the results of the research on paper/pulp quality after different treatments. Pretreatment that used Trametes versicolor fungi and lasted for 45 days inflicted intensive fiber damages compared with those of untreated bamboo (control). Fresh and barkless large (betung) bamboo chips of 2 years old, and 1.6 cm in length, were inoculated by 10% of mixed culture of white-rot fungi inoculums stock for 30 and 45 days in room temperature. There were four treatment groups of mixed culture, i.e T. versi color and P. ostreatus (TVPO); P. ostreatus and P. chrysosporium (POPC); P. chrysosporium and T.versi color (PCTV); and P.chrysosporium,  T.versicolorand  P.ostreatus  (TVPCPO).After  the  inoculation  period,  the  chips  weremacerated into separate fibers using Scultze method to analyze the fiber dimension and its derived values. The fibers were then observed regarding their macro and microscopic structures by optical microscope. Mixed culture pretreatment of white-rot fungi accelerated improvement of fiber morphology and fiber derived value characteristics, except for Muhlsteph ratio. The fiber derived values oftreated bamboo tended to improve compared to those of untreated bamboo, there by requiring milder pulping conditions. Accordingly, the treated bamboo would indicatively produce a good quality pulp (grade I) based on FAO and LPHH (Forest Product Research Report) requirements. Co-culture treatment using P. chrysosporium and P. ostreatus for 45 days produced the best fiber dimension and its derived value properties. The fungi hypae colonized on the surface area of  bamboo followed by mycelium penetration into substrate (bamboo-inner structure). The partial degradation caused by delignification indicatively attributed to the fungi activity was shown in the macroscopic images.
