Abstract

Forest and land fires are a high source of emissions in South Sumatera. In line with the national policy, South Sumatera Province commits in reducing emission, include emission from the forest and land fire. This research was aimed to assess carbon loss affected by fire in the year of 2015 that covered 3 districts in South Sumatera i.e Musi Banyuasin, Banyuasin, and Musi Rawas. The research was conducted by remeasurement of carbon stocks plots on 4 forests and land type i.e. secondary peat swamp forest, secondary dryland forest, bushes swamp, and forest plantation. Carbon stocks measuring are conducted on sample plots in a rectangular shape of 20 m x 50 m of size for various types of natural forest and a circle shape in the radius of 11.29 cm and 7.98 cm respectively for forest plantation of < 4 years and > 4 years old. Furthermore, carbon stocks in each plot are measured for 3 carbon pools of above-ground biomass, deadwood and litter. The result shows that carbon loss was varying on each forest and land type. The largest number of carbon loss occur on secondary peat swamp forest of 94.2 t/ha that equivalent to the emission of  345.4 t CO2eq. The second largest of carbon loss occur on secondary dryland forest of 36.3 t/ha following by forest plantation and bushes swamp of 18.5 t/ha and 13.5 t/ha. The largest carbon loss on secondary peat swamp forest and forest plantation occur on above-ground biomass pool but secondary dry forest and bushes swamp occur on the dead wood pool.

Abstract

Eucalyptus saligna tends to develop defects during its drying process, thus limiting its use as construction or furniture material. Intermittent drying, which applies non-heating phases between heating phases, has the potential to overcome this issue. This study evaluated the effects of 3 intermittent and 1 continuous schedule on the species’ drying performance and post-drying qualities. The results showed that the boards from all intermittent schedules exhibit significantly slower drying rates (from -9.4x10-3 /hour to -1.57 x10-2 /hour) than those from the continuous schedule (from -5.12 x10-2 /hour to -1.03 x10-2 /hour). The intermittently-dried boards also developed lower collapse depth (1.162-2.032 mm) than the continuously-dried boards (5.12 mm). Nevertheless, applying higher temperature than that used in the continuous schedule, during the heating phase of the intermittent schedule, potentially increased the moisture gradient, residual drying stress, end check length, internal check percentage, and spring depth.

Abstract

COMPARATIVE WOOD ANATOMY OF GENUS SYZYGIUM (FAMILY MYRTACEAE) FROM MANIPUR, INDIA. Syzygium belongs to family Myrtaceae and comprises of mostly trees and a few shrubs.  The main objectives were   to study   anatomical and physical characteristics of five Syzygium species namely Syzygium cumini, Syzygium fruticosum, Syzygium jambos, Syzygium nervosum and Syzygium praecox and to see intra and inter species variation among them. The wood samples were taken at breast-height from straight bole and uniform crowned trees. The present study showed that all the selected species shared common features like simple perforation plate, vestured inter-vessel pits, vessel-ray pits, disjunctive ray parenchyma cells, diffuse, diffuse-in-aggregate, vasicentric, aliform and confluent types of axial parenchyma Diffuse porous and indistinct fruticosum were observed. The vessels were mostly barrel shaped with small or long tails at one or both ends in all species except tube shaped in S. jambos and drum shaped in S. fruticosum. Spiral thickenings were present in the tails of S. nervosum and S. fruticosum. Fibres were thin walled and non-septate. Occasional septate fibres and vasicentric tracheids were present in S. nervosum and S. jambos. Crystals in ray of S. nervosum and S. fruticosum and silica bodies in axial parenchyma of S. jambos were observed. The fibre percentage and wood density were maximum in S. jambos whereas moisture content was minimum in S. jambos. Principal Component Analysis revealed a close relationship among all species. Therefore, the qualitative characteristics and all quantitative anatomical characteristics can be used for reliable identification of Syzygium species.

Abstract

Community Plantation Forest (HTR) is one among alternatives expected to fulfill the needs of timber.  Limited capital, which is simply known as financial capital, is considered as the main problem in HTR development. However, there is also other capital but less known and understood namely social capital. This study aims to determine the social capital that can be utilized in HTR management. The study was conducted in Rumbia Village, Boalemo District, Gorontalo Province. The data collected was analyzed using descriptive qualitative method in three steps: data reduction, data display and verification. In this study, the social capital is discussed in its dimensions of trust, norm and network. Results of the study show that strengthening social capital in its dimension of trust, norm, and network would encourage independence of both the farmers and forest farmer groups in HTR management. If the social capital does not work properly, gap among farmers could occur and even becomes a barrier or limits in involvement of members of the farmer group in the management of HTR. The farmers had high trust to forestry extension officer. It became a dimension of social capital that should be developed further in HTR management to reach optimally benefits from HTR land. In addition, the farmers also had a high compliance to social norms of traditions, religion and customary rules. The social capital hold by the farmers should be addressed in proper way by local and central government in order to develop successful HTR management.

Abstract

Indonesia has one of the largest tropical peatland areas in the world. In Sumatra Island, peatland is spread over 11 areas and it was mainly found in Riau (60.1%) and South Sumatra (19.6 %) Provinces. This study investigates the subsurface of tropical peatland in Ogan Komering Ilir Regency, South Sumatra Province. Data was recorded using Electrical Resistivity  Tomography (ERT) method based on the sub-surface images of tropical peatland. This study was conducted based on dipole-dipole configuration with 72 channels spread. This paper also studies the physical properties (thickness and electrical resistivity) of peatland and its substrate using ERT. In this study the ERT section and the geological map identified Alluvium (Qs), Kasai Formation, and the Basement. Result shows the ERT is applicable for imaging the thickness of tropical peatland and other geological features (Aquifer, geological structures, and stratigraphy). The electrical resistivity of peat varies from 20 ohm meter to 120 ohm meter and the thickness of peat varies from 2–5 meter. In some ERT sections, the basement was identified from 130 meter to 170 meter beneath the surface. The aquifer sweet spots were located from ERT Sections combined with the hydrogeological map. The aquifer was identified in Kasai Formation. The thickness of the aquifer layer is 2–20 meter. These physical properties may support the peatland conservation (forest fire mitigation) and geotechnical analysis purposes.

Abstract

This research aimed to understand the softening behaviour and viscoelastic property of wood, rattan, and bamboo as lignocellulosic materials. Nine years-old fast growing teak wood [Tectona grandis L.f.], rattan [Calamus sp.], and 3 years-old andong bamboo [Gigantochloa pseudoarundinaceae (Steud.) Widjaja] were used for the experiments. The samples were taken from the bottom, middle and upper parts for wood and rattan, and that for bamboo were cut from the 1st to 20th internodes. Static bending tests were carried out in fresh (green) as control samples, air-dried, and softened by microwave heating (MW) for 1 min to determine modulus of rupture (MOR) and modulus of elasticity (MOE). The results showed that the MOR and MOE values of wood, rattan, and bamboo increased from fresh to air-dried condition, and decreased by MW. When compared at the same density, drastic increase was observed for the normalized MOR value in air-dried of rattan, i.e. 2.5 fold. However, the decreasing of all the normalized MOR values were almost the same, i.e. 0.5 fold when they were softened by MW. Remarkably increase was also appeared for the normalized MOE value in air-dried of rattan, i.e. 3.0 fold and decreased to almost zero by MW. These results indicated that rattan was more easily bent, followed by bamboo and then wood. Hydrothermal properties of chemical components significantly affected the changes of strength (MOR) and elastic properties (MOE). However, the differences in bending strength of wood, rattan, and bamboo were more likely due to differences in their anatomical structures.
