Abstract:

This study investigated the roundwood production and profit sharing for Shorea leprosula and Shorea smithiana in case of PT Inhutani I Bukit Bangkirai, Balikpapan. Five research aims pursued in order to better understand the economic valuation of Shorea tree species, are: 1) analyse the increments of woody; 2) identify the age of trees reached the highest increments of woody; 3) measure the highest value of mean annual increments (MAI); 4) examine the nominal rate of return (i) for roundwood production; 5) examine the profit sharing between the management of PT Inhutani I Bukit Bangkirai and investors. Additionally, the policy of profit sharing has been determined by the proportion of 55% for investors and 45% for the management.The results demonstrated that: 1) the wood potential of Shorea leprosula reached the highest value at the age of 40 years by producing 7.78 m3 ha-1 year-1, and Shorea smithiana reached the highest value at the age of 50 years by producing 333.34 m3 ha-1 year-1; 2) the highest value of MAI for Shorea leprosula and Shorea smithiana are 7.78 and 6.67 m3 ha-1 year-1 respectively; 3) the nominal rate of return (i) of Shorea leprosula is 7.8% for investors and 8.3% for the management, and Shorea smithiana is 6.3% for investors and 6.7% the management. Overall, this research found that the economic value of Shorea leprosula and Shorea smithiana provide the nominal rate of return (i), which is higher than minimum acceptable rate of return (MAR).

Abstract:

Kurangnya informasi mengenai perubahan sifat kayu dari pohon bekas kebakaran hutan juga merupakan pertimbangan khusus yang menyebabkan belum dimanfaatkannya kayu bekas kebakaran hutan. Konsumen dalam hal ini perusahaan pengolahan kayu masih berpendapat bahwa kayu dari hutan bekas kebakaran sifat kayunya akan musnah atau berkurang. Dalam penelitian ini akan diteliti sifat-sifat mekanika kayu setelah terjadi kebakaran hutan, dimana akibat kebakaran hutan semua pohon terbakar tetapi ada yang bisa hidup dan ada juga yang langsung mati. Agar permasalahan tidak terlalu meluas, maka disini diperiksa pengaruhnya hanya pada jenis Meranti Merah (Shorea leprosula). Kesimpulan dari penelitian ini adalah sebagai berikut: 1. Ketangguhan kayu Meranti Merah (Shorea Leprosula Miq) tidak berubah secara signifikan akibat kebakaran hutan, 2. Kekuatan lentur dan ketahanan patah kayu Meranti Merah (Shorea Leprosula Miq) nilainya berkurang secara signifikan akibat kebakaran hutan yang terjadi 3. Hal tersebut di atas terjadi karena mati dan keringnya beberapa sel penyusun kayu akibat pengaruh panas, sehingga kayu cenderung bersifat keras.

Abstract:

<p>S. leprosula and S. parvifolia are widely developed as source of high quality wood. The quality of wood could be affected by nutrient elements. It is important to measure the nutrients contained in tree stem including wood density and fiber length due to their influence in tree growth. This research aims to know correlation between wood density and fiber length with distribution of essential macro-nutrients; N, P and K on stem base of S. leprosula and S. parvifolia trees. Wood density measurement followed DIN 2135 standard method, fiber length measurement followed FPL method, and nutrient measurement used AAS method. Further, the observation data was analyzed using SPSS 16 software. Wood density and fiber length on stem bases of both of tree species tended to increase radially from section nearby the pith to section nearby the bark respectively. Wood density of S. leprosula ranged from 0.333-0.362 with 1.279-1.343 µm in fiber length, while wood density of S. parvifolia ranged from 0.285-0.346 with 1.497-1.805 µm in fiber length. Distribution of nutrient N, P and K of stem base from pith to bark also tended to increase. On S. leprosula, nutrient elements N, P, K had significant correlation with wood density and fiber length. On S parvifolia, nutrient elements N, P, K had a significant correlation with wood density. Meanwhile, nutrient elements N, P, K had a non significant correlation with fiber length.</p><p><br /><strong>Keywords</strong> : Shorea leprosula, Shorea parvifolia, base of the stem, wood quality distribution, nutrient distribution.</p>

Abstract:

Shorea is a genus of the Dipterocarpaceae family which shows high economic and ecological values. Currently, market demand for wood is still met from natural forests that are degrading due to over exploitation. The degraded forests are included in the rehabilitation program that require significant number of planting stocks, mainly from seedlings or wildlings. Correct species identification of planting stocks, particularly wildlings, is an important first step in planting activities and it is relevant with Shorea spp planting stocks due to leaf morphology traits. This study was aimed to examine the traits of leaf morphology of four Shorea species for easy field identification. Samples were taken from five trees for each species. Morphological trait identification was conducted by leaf observation and measurement. The results showed that all four species had the same apex shape. Six of the twelve morphological characteristic of the variable character can influence the morphological characteristics of the leaves, namely the roving leaf, leaf area, leaf length, aspect ratio, form factorand perimeter ratio of diameter. S. leprosula is similar to S. parvifolia, while S. ovalis is similar to S. guiso. Shorea leaf character S. parvifolia differentiated from S. leprosula, while Shorea ovalis similar to Shorea guiso. The LP variable (length from the base of the leaf to the widest point of the leaf) is a variable that can be used as aleaf morphological characteristic of the four Shorea which are compared because each one has a different value. S. ovalis has the highest LP value, followed by S. guiso and S. leprosula, while S. parvifolia has the lowest LP value. Keywords: apex shape, identification, leaf morphology traits, Shorea

Abstract:

Shorea acuminata Dyer, Shorea curtisii Dyer ex King, Shorea leprosula Miq., and Shorea parvifolia Dyer are dominant tree species in the tropical rainforest of Peninsular Malaysia, which experienced several climatic changes during Pleistocene. To investigate the current population structure and demographic history of these species, we analyzed levels and patterns of nucleotide polymorphism of the nuclear gene region PgiC. We also used sequence data of the GapC gene region obtained in our previous study. Negative Tajima’s D values observed in both investigated gene regions for S. curtisii, S. leprosula, and S. parvifolia implied that all three species have experienced population expansion events. Little to moderate levels of population differentiation in S. acuminata and S. curtisii suggested recent divergence of the investigated populations after postglacial colonization of the Peninsular Malaysia. In addition, some haplotypes were similar or identical to haplotypes of the other species. The existence of such haplotypes could be partially explained by interspecific hybridization. Indeed, we found some putative hybrid individuals. Interspecific hybridization among closely related species might have contributed to the polymorphism of the investigated species.

Abstract:

Abstract The development of sequence characterized amplified region (SCAR) markers derived from amplified fragment length polymorphisms (AFLPs) is described for Shorea leprosula. An AFLP fragment that showed nearly complete differentiation between Borneo and Sumatra was gel-extracted, sequenced, and converted into a SCAR marker using the inverse polymerase chain reaction (PCR) technique. The single nucleotide polymorphism (SNP) that originally caused the AFLP was found in the MseI restriction site. Differentiation between islands was detected either as size variation of the codominant SCAR marker or after digestion of the PCR products with the restriction enzyme MseI (PCR-RFLP). Size variation was due to insertions/deletions found within the sequenced region that flanked the original AFLP fragment. After genotyping 151 samples of S. leprosula from 14 populations in Sumatra and Borneo, all but one sample from Sumatra were homozygous for one size variant (427 bp), while S. leprosula populations from Borneo showed different genotypes than Sumatra populations and variation not only among populations but also within populations. Complete differentiation and fixation on alternative variants was found for the geographic regions of Sumatra and Borneo by the PCR-RFLP method. The SCAR marker did not amplify in Shorea parvifolia and thus can also be used to distinguish between S. leprosula and S. parvifolia. The marker was successfully amplified from wood DNA extracts suggesting its applicability to track the geographic origin of timber.

Abstract:

High productivity fast growing species plantation establishment such as the line planting of red meranti (i.e Shorealeprosula and Shorea parvifolia) with intensive silviculture is one potential solution to improve wood supply for industries in Indonesia. However, the information of anatomical properties and wood properties of these two species related to the influence of the line planting system and tree growth rate is limited. This paper studies the anatomical features, wood cell proportions, fiber dimensions and physical properties of wood in radial variation in relation to the line planting effect and tree growth rate. Wood of the trees grown in the line planting system showed higher proportion of vessel element compared to those of wood from natural forest. The vessel diameter of wood from the line planting was also larger than that of in wood from natural forest. The specific gravity of wood from Shorea parvifolia grown on the line planting was higher than that of wood grown in natural forest. The variation of specific gravity on wood portion near to the pith of Shorea leprosula and Shorea parvifolia trees grown on the line planting was related to the variation of the cell wall thickness. The bigger diameter of trees grown or the faster growth rate in the line of planting at the same age shows the greater vessel diameter in wood of Shorea leprosula and Shorea parvifolia and greater specific gravity of Shorea parvifolia wood.

Growth patterns of Shorea leprosula and Dryobalanops lanceolata in Borneo’s forest managed with Selective Cutting with Line Replanting System. Biodiversitas 20: 1160-1165. Dryobalanops lanceolata is a species of plant in the family Dipterocarpaceae, which indigenous of Borneo. It is found in at least five protected areas (Kabilli-Sepilok Forest Reserve, Danum Valley Conservation Area, Ulu Temburong, Lambir, and Gunung Mulu National Parks), but is threatened elsewhere due to habitat loss. The demand for its timber is very high, so it requires conservation efforts while at the same time maintaining its productivity to meet the timber demand. One of the efforts to increase productivity of production forest in Indonesia is implementing Selective Logging with Line Replanting System (TPTJ). In this system superior species are planted in the planting lines. This study aimed to determine the growth of Shorea leprosula and Dryobalanops lanceolata planted in different planting line widths. Data of diameter increment of S. leprosula and D. lanceolata were obtained by observing 4 permanent sample plots (PUP) at concession areas of PT Balikpapan Forest Industries in Penajam Paser Utara, East Kalimantan, Indonesia. The results showed that the average diameter increment of S. leprosula and D. lanceolata at the planting line width of 3 meters was 1.47cm/yr and 0.74 cm/yr respectively, and at the planting line width of 6 meters was 2.08 cm/yr and 1.14 cm/yr respectively. The differences in planting line width had very significant effect on the growth and diameter increment of S. leprosula, presumably due to the increase of light intensity to optimal level which accelerates stomata opening and transpiration rate, thus affecting the rate of photosynthesis.

Abstract:

Abstract Dipterocarp trees are ecologically and commercially important in Southeast Asian tropical rainforests. For sustainable management of forest ecosystems and conservation of biodiversity, it is essential to establish plantation methods ensuring that genetic variation of the planted trees is equivalent to that in natural forests. The genetic diversity and differentiation of Shorea leprosula and Shorea parvifolia on plantations managed by a private-sector forestry company in Indonesia and those in natural populations were compared using microsatellite markers. Genetic diversity in the planted populations was as high as that in the natural populations. No clear genetic differences between each planted population and the natural forest populations were found. The genetic variation present in planted S. leprosula and S. parvifolia populations did not appear to deteriorate in the planting system implemented in Indonesia, known as Tebang Pilih Tanam Jalur (TPTJ). These results indicate that the current plantation method practiced in the region is suitable for maintaining the original genetic composition and achieving sustainable use of tropical rainforests.

Abstract:

Combo nursery technique is a technique where seedlings/cuttings of Shorea leprosula, Gliricidia sepium, and Brachiaria decumbens grass were planted in one polybag to support mining reclamation. To reduce competition effects among the three species, optimum media and size of polybag need to be investigated. The objective of this experiment is to analyse the effect of size of polybag and media composition on the growth of S. leprosula, G. sepium, and B. decumbens grass in the combo nursery technique. The experiment used Randomised Complete Design in Factorial with two factors, i.e. media compositions (soil : compost (2 : 1, v/v), (1 : 1, v/v), (1 : 2, v/v), and soil : compost : rice husk (7:3:1, v/v/v); and size of polybag (15 x 20 cm, 20 x 20 cm, dan 25 x 25 cm). Each treatment had four replications, and each replication consisted of four polybags. The results showed no significant interaction effects between the composition of media and the size of polybag; however, media compositions of soil: compost (1:1) and (1:2), and the sizes of polybag 20 x 20 cm and 25 x 25 cm significantly eliminated competition and significantly increased the growth of S. leprosula and the number of tiller of B. decumbens grass.

Abstract:

AbstractThe development of molecular markers unambiguously distinguishing groups at different taxonomic levels has numerous forensic applications. The identification of tropical timber is of particular interest in this context. We describe the development of SCAR (Sequence Characterized Amplified Region) markers for forensic applications taking the example of two closely related species of the tropical tree family Shorea (Dipterocarpaceae). Two AFLP (Amplified Fragment Length Polymorphism) fragments have been described earlier showing strong differentiation between S. leprosula and S. parvifolia. The AFLP markers were isolated from a gel, re-amplified, cloned and sequenced. Primer sets were designed from these sequences and AFLP fragments were converted into SCAR markers. The SCAR markers and PCR-RFLP markers of the chloroplast region trnLF digested with HinfI were used to screen in total 557 samples of S. parvifolia and S. leprosula from nineteen widely separated populations in Indonesia. Complete genetic differentiation between species was observed based on the putatively nuclear SCAR marker and the PCR-RFLP of the cpDNA region. We found a good agreement between leaf morphological variation and species identification based on both marker types and no indication for interspecific hybridization.

Abstract:

Information on calorific value is very important factor in fuel evaluation. The objective of the study was to investigate the calorific values of the leaves of five (5) selected trees species of dipterocarp in Piah Forest Reserve, Perak, Malaysia. The species are Hopea sp., Shorea parvifolia, Shorea leprosula, Shorea macroptera and Dipterocarpus sp. The calorific values were determined using the Adiabatic Bomb Calorimeter. The difference of calorific value between the five species were also examined. It was found that, the mean calorific value for the dipterocarp species were within the range of 4041.28 Cal g-1 to 4820.78 Cal g-1. The leaves of the Shorea macroptera contain higher calorific value compared to other four species. The findings will be useful in the preparation of forest fire management plan, and also in the development of bioenergy project of wood-based biomass from forest species.

Abstract:

Vegetative propagation has an important role in production of high quality planting stocks. Through vegetative propagation, the genetic potential of a mother tree will totally be inherited to the off-springs.This study aimed to determine the effects of population sources and clones on growth variation of Shorea leprosula Miq shoot cuttings. Randomized Complete Block Design (RCBD) was used as an experimental design; which consists of two factors, i.e population sources (Muara Wahau, Berau, Kenangan, Ketapang and Carita) and clones (40 clones). In this study clone was nested in the population. The results showed that the clones and population sources influenced the rooting percentage, height growth, number of root, length of root and number of leaves of S. leprosula shoot cuttings. Rooting percentage of clones ranged between 66.7 – 100.0% (2 groups difference), height growth ranged between 2.60 – 6.80 cm (6 groups difference), number of root ranged between 2.1 – 5.7 (9 groups difference), length of root ranged between 4.3 – 15.8 cm (8 groups difference) and number of leaves ranged between 1.17 – 3.57 (5 groups difference).

Abstract:

Vegetative propagation plays an important role to support Shorea leprosula’s clonal forestry development. This study aimed to determine the effect of mother trees and cuttings material position of S. leprosula shoot cuttings growth at 4 months of age. Complete Randomized Design (CRD) was used as the experimental design, which consists of two factors, i.e. cuttings material position (4 level) and mother trees (10 mother trees). The results showed that the interaction between mother trees and cuttings material position significantly affected the growth of height and the number of the leaf. The best interactions in height of growth values ranged from 7.83 to 8.83 cm and the best number of leaves ranged from 3.6 to 4.5 sheets. The single factor of the cuttings material position and mother trees significantly affected the rooting percentage, the number of the root, and the length of the root. The cuttings material position at 20 cm, 40 cm, and 60 cm found to be the best rooting percentage (84 to 88%), the cuttings material position at 40 cm and 60 cm found to be the best number of the root (4.04 to 4.43 pieces) and the best length of the root (10.23 to 10.93 cm).

Abstract:

The wood formation of kapur (Dryobalanops sumatrensis) and tembaga (Shorea leprosula), growing under a weak seasonal climate in West Malaysia was studied over a four-year period using cambium marking. Technical problems arose from the heavy callus formation due to the wounding of the cambium, the small radial increment, and the high variability of the cambial activity around and along the stem. Wood formation in the two tree species appears to be a continuous process and not related to seasonality in rainfall and phenology.

Abstract:

Logging activities have an impact on changes in composition and standing structure, tree species distribution, community similarity and species diversity. This study aims to determine the diversity of structures and standing composition of logged-over forests. The results show that the composition and structure of the stands are ecologically different, which is indicated by the low type of species equality index. The types of stands at the level of seedlings, stakes, columns and trees from each location are almost all different. But there are some of the same types encountered dominating on the locations of 2005, 2010 and 2015 such as Shorea leprosula, Dipterocarpus borneensis, Shorea laevis, Litsea sp. The stand density at the 2005 block location is higher than the two sites in 2010 and 2015, while the location of 2015 is the location with the lowest stand density.

Abstract:

Pieces of red meranti wood (Shorea leprosula) were soaked in horizontal and vertical positions in sea water for 9 weeks. Two species of bivalves settled on the wood: Bankia campanellata (Moll & Roch) and Martesia striata (Linné). Average densities of settling larvae were 125 ind. 100 cm-2 on horizontal wood, and 95 ind. 100 cm-2 on vertical wood, indicating a tendency to settle on the top side of the wood. The number of larvae settling on wood immersed at the surface was not significantly different from wood at 1.25 m depth.

Abstract:

Leaf defences, leaf nutritional quality and leaf expansion rates may vary with resource availabilities to plants. Such variation could affect rates of leaf loss to herbivores, particularly along the steep resource gradients in disturbed forests. Intraspecific and interspecific variation in leaf damage and leaf expansion rates were measured on dipterocarp seedlings planted into secondary forests 1, 5 and 15 y after logging, and in adjacent primary forest of Sabah, Malaysia. Herbivory rates or amounts of leaf damage were compared across habitats and species for expanding, recently expanded, and mature leaves of Shorea leprosula and Dryobalanops lanceolata (Dipterocarpaceae). In all four habitats, leaves of the faster growing S. leprosula sustained higher rates and amounts of leaf-area loss than did the tougher leaves of slower growing D. lanceolata. Expanding leaves accumulated more leaf-area loss per week than did mature leaves. In all habitats and in both species, more than 25% of expanding leaves disappeared entirely. Rates of leaf-area loss per week differed among habitats for expanding leaves but not for mature leaves. In a relatively open, 1-y-old logged forest, faster leaf expansion reduced the time leaves spent in the most vulnerable stage; however, in S. leprosula a greater rate of leaf area loss countered the shorter expansion time. Thus, leaves accumulated similar total damages across habitats, and herbivory did not produce differences among habitats in seedling growth or mortality. High levels of resources may increase both leaf palatability and leaf expansion rates, with counteracting effects on herbivory.
