Coal mining activities in Indonesia result in heavy soil degradation and significant decrease in earthworm population. This study aims to explore the population of earthworms at different ages of the plant in the post coal mining rehabilitation areas. PT. Kideco Jaya Agung, East Kalimantan. In this study, 5 samples (30 cm x 30 cm, 20 cm depth) of soil were collected from 5 rehabilitation sites. Sites were selected based on age after rehabilitation: 2, 4, 6, 8 and 10 years after replanting, and sampled with 20 m distances between samples to determine earthworm population. The depth of litter layer and species of plants were also recorded at each site. Chi square analysis was conducted to determine the significance of earthworm density in rehabilitation sites at different ages, while correlation analysis was conducted to determine correlation between litter thickness and the number of earthworms found in the research sites. Only 2 species of earthworms were found in this study; their abundance increased increased in line with the age of rehabilitation areas. The number of earthworms (density) at 10 years after rehabilitation was almost similar to that in the natural forests. In conclusion, planting tree species producing significant amount of litter might stimulate the earthworm community and initiate succession. It might also take more than 10 years to return to the previous state for the earthworms in terms of density after land rehabilitation of the coal mining areas is conducted.

Various rattan species grow naturally in Jambi, Indonesia, i.e. opon (Plectocomiopsis geminiflora (Griff.) Beccari), udang (Korthalsia flagelaris Miquel), getah (Daemonorops micracantha (Griff.) Beccari), duduk (D. didymophylla Beccari), tunggal (Calamus laevigatus Martius), sijau (C. tumidus Furtado), buruk ati (C. insignis Griff. var. longispinosus Dransfield), batu (C. zonatus Beccari), and paku (C. exillis Griff.). The rattan species are classified as lesser known species, which its properties are unknown to rattan supplier and consumers. This paper observes the anatomical properties of nine indigeneous rattan species of Jambi. Anatomical observations were conducted from solid, sectioned and macerated samples. Results show that anatomical properties become a diagnostic characteristic for rattan species identification and specific characteristic has been developed for key species determination. Vascular bundles in the outer part of the stem of opon and udang rattans are yellow-capped. Width and length ratio of vascular bundle in the outer part is more than 1, oval shape was found in sijau rattan, while elongated shape vascular bundle with the ratio less than 1 was found in buruk ati. Fiber bundles separated from vessels are found in central ground parencymatous tissue of rattan tunggal. In the peripheral area, fiber bundle forms one or two lines with no specific pattern found in rattan paku, while fiber bundles in one line with alternate pattern found in rattan duduk. Single resin canals are found both in center part and peripheral area is found in batu rattan and mostly single. Resin canals are found in pair at getah rattan stem. Tentative identification key to rattan species has been developed for nine species investigated, then the key should be developed for further genera identification among rattan species in Indonesia.

The productivity of exotic species developed in pulpwood plantations in Indonesia (HTI-pulp) has been continuously decreasing. On the other side, there is a possibility to develop several promising native tree species in peatland HTI-pulp plantations. However, less information is available on the performance of those native tree species for planting in peatland pulpwood plantation. This study evaluates the performances (survival rate, growth and yield) of three native trees [mahang (Macaranga pruinosa), skubung (Macaranga gigantea) and geronggang (Cratoxylum arborescens)] in drained peatland, in terms of suitability for pulpwood plantation. An experiment plot was established by planting three native tree species and krasikarpa (Acacia crassicarpa) in drained peatland at Pelalawan District, Riau. Survival, growth and yield variables were monitored frequently until 5.5 years after planting (YAP) and then were analyzed. Geronggang (survival rate = 80.0%) and mahang (survival rate = 65.6%) showed good survival rates at 5.5 YAP which were significantly (p<0.05) higher than that of krassikarpa (22.4%). Geronggang and mahang are relatively promising growth and yield in which height, diameter and yield increment until 5.5 YAP were 1.96 m/year and 2.31 m/year; 2.08 cm/year and 2.59 cm/year; 13.1 m3/ha/year and 21.4 m3/ha/year, respectively. Yet, those growths and yields were still significantly (p<0.05) lower than those of krasikarpa, probably due to unequal seedling quality. These results indicated the potential of mahang and geronggang to be developed in peatland pulpwood plantations. However, tree improvement program is necessarily required for mahang and geronggang to initiate the development.

Currently, clonal of forest tree is gaining importance due to the yield improvement and low variability in different wood characteristics. Hybrid trees from clonal forest are importantly characterized in term of wood quality for finding suitable uses. Accordingly, three clones (HD3, K47, H4) of 8-year-old Acacia hybrid (Acacia mangium × A. auriculiformis) were evaluated for inter-clonal comparison of its wood quality by evaluating their physical and mechanical properties as per Indian Standards. All tree clones were studied at breast high including diameter, heartwood content, and physical and mechanic properties. The Dbh of all three clones was around 30–35% and 60–70% greater than pure forms of A. auriculiformis and A. mangium of the same age, respectively. The volumetric shrinkage of all three clones was found to vary from 7.8 to 8.6%. The low shrinkage values may be attributed to higher dimensional stability of the wood of these clones. The data obtained in green and air-dry conditions were used to calculate ‘suitability indices’ with respect to teak (Tectona grandis) which was taken as a reference wood for comparison in India. All the suitability indices that these clones were either comparable or slightly lower than those of pure forms of A. auriculiformis and A. mangium. Less inter-clonal variation was observed in most of the suitability indices. Though, all the three clones were exclusively grown for their use in pulp and paper industry, but the comparative suitability figures for different end uses indicate that these clones could also be used for certain non-structural applications such as tool handles, light packing cases, pallets and light furniture.

The use of natural antioxidants for medicinal purposes deserves thorough attention for their efficacy and possibly adverse toxicity. This paper studies the antioxidant actions and toxicity effects of bark extracts. The study focuses on eleven tree species of Euphorbiaceae family. Initially, bark samples from those trees were extracted using ethanol. The acquired extracts were examined for peroxide values with iodometric method. The bark extracts were chemically screened for possible antioxidant-compound contents, i.e. polyphenols, flavonoids, and saponins; and followed by oxidation-reduction test to assess the extract ability in vitro to scavenge free radicals in their standard sources, i.e. 2,2-diphenyl-1-picrylhydrazyl; altogether to determine qualitatively which species origin from bark extracts afforded the most potential as antioxidants. Toxicity test was performed on those bark extracts to assess their safety on living creatures, particularly humans as tried on shrimp larvae by counting their death, using the Brine Shrimp Lethality Test method. Results show that bark extracts of four plant species, i.e. Acalypha hispida Blume, Bischofia javanica Blume, Glochidion arboreum Blume and Sapium baccatum Roxb species afforded potentiality as antioxidants, because its peroxide value (POV) was lower than or somewhat above those of the positive control vitamin E (POV 89.45 μg/ml). However, bark extracts from Euphorbia antiquorum L, Euphorbia hirta L, and Jatropha podagrica Hook (i.e. LC50 : 238.85; 228.11 & 194.51 μg/ml) were highly toxic, because their LC50’s value< 1000 μg/ml.

Local communities have been using forest land area far before Industrial Forest Plantation (HTI) permit was granted. The overlapping land use among different users potentially leads to conflict. This paper studies conflict resolution creatively and collaboratively with forest management. Conflict resolution is based on the Creativity and Collaboration Action - Forest Management (CCA-FM) model on field exploration that created participation pattern of all parties in the vision of forestry science principles as the basis of policymaking. Convergent Parallel Mixed Method (CPMM) approaches with Rapid Land Tenure Assessment (RaTA) were used. Results show that claim of the community as the owner of the authority rights and dominance of the local elites, greatly affect the action situation. However, the policy options taken by the government towards policy outcomes do not tend to consider the field conditions. The CCA-FM model has been implemented in five villages. The community strongly supports the government to devolve the management rights to the community and to facilitate the transfer of knowledge, technology, market information, supporting all parties, and collaboration on business license management. Research results recommend the CCA-FM model could be a basis for building village self-reliance and improving the performance of the Forest Management Unit (FMU).
