Indonesian Journal of Forestry Research (IJFR) was first published as Journal of Forestry Research (JFR) in November 2004 (ISSN 0216-0919). The last issue of JFR was published in December 2013. The Journal has been accredited by the Indonesian Institute of Sciences since 2008 and by the Ministry of Research, Technology and Higher Education since 2018. IJFR has also obtained accreditation “Peringkat 1” or “Rank 1” from the Ministry of Research and Technology/National Research and Innovation Agency in 2020 (Decree Number: 200/M/KPT/2020). IJFR is issued in one volume per year, including two issues delivered in April and October. IJFR was previously published by the Research, Development and Innovation Agency - the Ministry of Environment and Forestry, formerly known as Forestry Research and Development Agency (FORDA) - the Ministry of Forestry, Republic of Indonesia. Due to national policy change in research institution, the Ministry would no longer manage and publish the IJFR. Therefore, since 2023, the management and issuance of the IJFR is handed over to the Association of Indonesian Forestry and Environment Researchers and Technicians (APTKLHI). Consequently, the logo of the publisher was updated accordingly. The Indonesian Forestry Research Journal is a scientific publication of the Association of Indonesian Forestry and Environment Researchers and Technicians (APTKLHI). This journal publishes the latest results of main findings and synthesis articles that contain significant contributions to science and theoretical applications in fields related to the scope of forestry research.

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.

Abstract

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

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

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.

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

Mantangan (Merremia peltata) is a plant species which invades the habitat of herbivorous animals such as elephants and rhinos in Bukit Barisan Selatan National Park (BBSNP) Sumatera, Indonesia. One possible way to overcome the problem is by providing M. peltata as livestock feed. This paper observes potential use of mantangan for goat feed. The study was conducted at Tampang Tua Village, a buffer zone of BBSNP where most of communities are farmers. The study and treatment were given to 6-7 months old goat breeders with an initial weight of 7-8 kg. Additional forage feed data were collected during March to June 2014. The research was designed as Latin Square Design with four treatments and four replications. The treatments consisted of four formulations namely: treatment A (field grass), B (field grass + 200 g mantangan), C (field grass + 400 g mantangan), and D (field grass + 600 g mantangan). Field grass is available continuously (ad-libitum). Results shows that the treatments significantly affect feed consumption level (P <0.05), but it did not have significant effect to body weight (P> 0.05). In other words, mantangan is potential for animal feed. This research was conducted as an effort to manage invasive alien plant species by utilizing mantangan as feed for livestock.

Abstract

The rise of pulp and paper production due to market’s demand will also increase both main and secondary products of pulp. Secondary products such as pulp sludge have low economic value, but high environmental cost. Therefore it needs improved technology input to raise its value. This study aims to evaluate the ability of Phanerochaete chrysosporium, a combination of Penicillium citrinum and P. oxalicum and a mixture of those three fungal species in decomposing pulp sludge after one and six months incubation. The pulp sludge was collected from pulp company in North Sumatera, Indonesia and it was pre-treated prior to composting. The composting was conducted by inoculating P. chrysosporium, a combination of P. oxalicum and P. citrinum or a mixture of those fungal species with a density of 107 spores/ml into 15 kg treated sludge. The inoculated sludge was then incubated for one and six months. Analysis was held for the non-inoculated and inoculated sludge regarding pH, cation exchange capacity (CEC) (me/100 g), macronutrients (N, P, K, Ca and Mg) (%), micronutrients (S, Zn) (ppm) and heavy metals (Pb, Cd) (ppm). After one month incubation, P. chrysosporium was leading in enhancing sludge’s macro and micronutrients. After six months incubation, a combination of P. oxalicum and P. citrinum generated higher P, K, CEC and reduced lead content of the sludge. Meanwhile, a mixture of the three fungus species produced the highest N and Mg.

Abstract

Peat soil with its unique physical and chemical character is host to various microbe and fauna. In the peat, the existence of microbe and macrofauna influenced by several environmental parameters. Therefore, in this study we would like to obtain the information about fungi and macrofauna in the post fire degraded peat swamp soil with emphasize on two points which are (i) abundance of soil fungi and soil macrofauna (ii) to describe the environmental parameters (e.g. understory and chemical properties) on the existence of fungi and macrofauna community. Soil dilution and pitfall trap were used to collect microbes and macrofauna in the targeted post-fire peat soil: Post-fire peatland /bareland (A), post-fire peat-land revegetated in December 2016 (B), post-fire peat-land revegetated in April 2016 (C), post-fire peat-land revegetated in December 2015 (D). Result showed that abundance of soil fungi obtained during this study is 4×105 to 11×105 cfu/ml. While the macrofauna abundance is 353-1038 ind/m2. Fungi and macrofauna community in peatland affected by understory cover which related with revegetation activity. There is a trend of increasing the abundance of microbes and macrofauna on the land along with the increase of the percentage of understory cover.

Abstract

Forest Tenure Reform implementation involves diverse actors with multiple roles and interests, including government officials. Few studies have attempted to systematically document the conditions facing government agency implementers in their efforts to implement forest tenure reform. This study attempts to identifies factors that enhance or constrain reform implementation from the perspective of individual implementers at national and sub-national levels in Indonesia. The study was conducted through analysing data that resulted from bureaucrat’s interview who purposively selected at Central and Local Government. Most interviewees indicate that forest tenure reforms have three interrelated objectives: to conserve forests and restore degraded forests, to improve community livelihoods and ensure benefits are equitably distributed; and to secure the rights of local, forest-adjacent or forest-dwelling communities. Reform implementation has been effective or somewhat effective in protecting community rights to access, use, manage and benefit from forests. Close to half of the respondents indicated that their activities gave special consideration to low income groups but few paid special attentions to women and women’s rights. Main constraints to implementation are inadequate budgets and insufficient manpower to execute tenure-related activities. Divergent priorities between national and sub-national/local levels and changes in government that redistribute personnel are additional factors that hinder reform implementation. Overall, respondents agree that reforms are only partially implemented due to technical and institutions constraints, which in turn influence the extent to which collaboration/coordination among actors can be achieved and the extent to which community tenure needs such as conflict management and resolution can be addressed.

Abstract

Globally energy crisis is known as a new era’s biggest problem. The use of agricultural wastes into the form of briquettes are the best alternative option of renewable energy sources. This paper studies the possibility of utilizing agricultural wastes into briquetting production with high calorific value. Major wastes were sugarcane bagasse, coffee husk, wheat straw, peanut shells, rice husks, paddy straw, corn stalks, sunflower stalk, soybean husk, coir pitch, jute sticks, caster seed shells, mustard stalks, cotton stalks and tobacco wastes for energy in the form of briquettes biomass. Observations were taken from Department of Bioenergy, Tamil Nadu Agriculture University, Coimbatore (Tamil Nadu), India of different raw materials and briquettes of those raw materials. Results show that there were very satisfactory results after evaluation. In general, calorific value briquettes is higher than those of raw materials. Raw materials of agricultural wastes and forest residual wastes ranged from 1,200-3,000 Kcal/Kg and its calorific values are significantly higher in briquettes than raw materials. Raw material of rice husk produces 3,000 Kcal/kg and briquettes of rice husk produces 3200 Kcal/kg. Likewise differences were observed in all types of agricultural wastes. The input and output ratio ware observed as cost-effective and profitable in all parameters for the farmers. Briquetting production is the emerging, ecofriendly, cost effective and profitable technology for the use of agricultural residues. It may help farmers to improve its socio-economic status and proper reuses of agricultural wastes.
