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

Indonesian government has launched a community plantation forests program that would be beneficial for remedying shortage in domestic demand for teak wood every year. This program needs to be supported by the availability of quality seeds resources and quality seedlings utilizing polyploid teak (Tectona grandis). Our study aimed to examine the effectiveness of colchicine and oryzalin to modify diploid into polyploid T. grandis based on growth response, morphological, anatomical and cytological alteration, as well as the acclimatization ability of polyploid plantlets. The materials used were aseptic lateral shoots consisting of nodal segments which were immersed in antimitotic agents at the concentration of 0, 15 and 30 μM for 5 days, then cultured on regeneration medium until the 8 weeks and followed by acclimatization. The results showed that colchicine at the concentration of 30 μM was the most effective to induce polyploidy of plantlets in the parameter of high growth rate, the length of internodes, the number of leaf plantlets and increase the leaf surface area and the significant chlorophyll index content compared to the control. Anatomical analysis of polyploid was characterized by increasing the leaf thickness, stomata size, decreased stomatal density and increased chloroplast content in guard cells. Based on cytological examination on polyploidy plantlet, there was an increased in the number of chromosomes in the cell nucleus. The acclimatization of polyploid successfully induced rooting and a 100% survival rate of grown plantlets. Polyploid seedlings were able to grow and well adapted to the new environment of acclimatization

Abstract

For sustainable forestry management and environmental protection, it is crucial to compare three wood types and processes in order to optimise charcoal production. The purpose of this study was to evaluate the viability of using diverse waste materials and carbonization techniques to produce wood charcoal. The upcountry wet zone and low-country dry zone regions of Sri Lanka provided the samples, which were each repeated ten times and came in three different sample sizes. To make charcoal, these samples were put through the barrel and pit processes. The results showed that the barrel method produced 28% charcoal instead of the 21% produced by the pit method, demonstrating its higher efficiency and cost-effectiveness. This improvement was ascribed to the barrel's enhanced ability to regulate airflow and temperature during pyrolysis. The study emphasizes the use of wood off-cuts and the barrel method to increase efficiency, save costs, and improve charcoal quality. It provides helpful advice for small charcoal producers.

Abstract

Cardamom (Amomum cardamomum), the ‘Queen of spices’, is a native Indonesian spice, a type of potential biopharmaceutical currently prospective because of its high selling value, especially for its fruit, with various benefits and its wide use. So far, cardamom essential oil comes from the utilization of its fruit, but the production is more limited, unlike the sustainably produced leaves, therefore, its leaves have the potential to be developed. This study aims to analyze the essential oil yield and 1.8-cineol content of cardamom leaves essential oil (CLEO) grown in agroforestry systems. The CLEO was obtained by steam-water distillation, while the 1.8-cineol content was analyzed by gas chromatography–mass spectrometry (GC-MS). The experimental design employed was a Randomized Complete Block Design with three cropping patterns as a treatment and three doses of bokashi fertilizer as blocks. The results showed that the highest yield of CLEO was generated in the sengon + cardamom agroforestry pattern of 3.16%, and the highest content of 1,8-cineol in CLEO was generated in the sengon + cardamom + arrowroot agroforestry pattern of 47.23%, while the lowest yield of CLEO and the 1,8-cineol content were found in the monoculture pattern of 2,02% and 43.16% respectively. Agroforestry practices have the potential to increase 1,8-cineol content and the yield of essential oil in cardamom leaf, which will be prospective in forest management to support forestry multi-business and social forestry programs.

Abstract

Pinus cernua L.K. Phan ex Aver., K.S. Nguyen and T.H. Nguyen (Pinaceae) is a critically endangered species restricted to the Laos - Vietnam border. The population of this species has been declining due to habitat loss and forest fire. Predicting the potential distribution of the species is an important priority for conservation plans and strategies. In this study, a MaxEnt model was used for predicting the potential distribution of P. cernua using 21 occurrence data and 13 environmental variables. Precipitation of driest month (with 32.3% of contribution), annual mean diurnal range (23.4%), elevation (18.4%), and aspect (12.3%) are crucial factors for predicting the species’ potential distribution in the MaxEnt model, while remaining factors are less important factors. The suitable distribution was predicted in the north-western region of Vietnam and the adjacent regions of Son La and Thanh Hoa provinces (Vietnam) and Houaphan province (Laos) with 1,544 km2 in total. The high, medium, and low suitability areas are 159 km2 (10%), 475 km2 (31%), and 910 km2 (59%), respectively. The current protected areas do not contain many of the possible habitats for this species. Priority should be given to conservation efforts for species in these potentially suitable locations both in- and outside of current protected areas, particularly in the surrounding area of Vietnam and Laos.

Abstract

Privately owned forests (POF) play an important role in Indonesia’s social, economic, and environmental spheres. The success of optimizing their roles relies on the traditional management practices carried out by farmers. Therefore, this study aimed to explore POF traditional management by farmers, POF performance, and their influencing factors. Respondents included 170 farmers selected by simple random sampling and key informant. This study was conducted in three villages across Ciamis Regency, West Java, in 2022. Data was collected through structured questionnaires, in-depth interviews, and field observations.  The collected data was tabulated, graphic, categorized, and descriptively analyzed. The results showed that although the knowledge about POF management was constantly developing, not all farmers applied their knowledge. POF management practices were found to be closely related to marital status, farming experience, land area, distance from home, number of parcels, and income. Furthermore, traditional management practices were reflected in POF performance; the higher the management level, the better the performance, and vice versa. Equitability and efficiency were high across all locations; productivity was low, while sustainability was only high in Kalijaya Village. The different conditions of each element of POF, show that although POF might not be optimal in terms of economic contribution, its sustainability provides environmental benefits. This study has many limitations as it only looks at factors within POF farmers that influence POF management and performance.  Further research into external factors that can influence POF performance and encourage an increased economic role for POFs can be explored in more depth

Abstract

Non-timber forest products (NTFPs) are biological elements other than wood that are usually collected from forests for human and animal use and have both a consumptive and an exchange value. NTFPs provide a major contribution to the livelihood and health of the poor. The article aims to describe the present condition of NTFPs and marketing issues for NTFPs in India, as well as their importance in improving rural livelihoods. A systematic research review approach was used to get the desired results. The study retrieved approximately 238 articles from different databases and filtered 191, highlighting 51 articles related to the keywords, published between 1988 and 2022 were included in the analysis. During the investigation, forty-one numbers of NTFPs were identified and documented, and numerous potential NTFPs for enterprise growth have been identified according to the different zones of India. Rural people are using NTFPs for a wide range of uses, including food, fodder, fibre, traditional medicine, domestic items, agricultural equipment, and construction materials, and many of them are linked to cultures. Promotion and domestication of NTFPs, as well as suitable policy frameworks for harvesting and better processing techniques, are all required for increased food security, poverty reduction, and improved livelihoods. Site-specific and species-specific strategies may be created for the preservation, management, and exploitation of NTFP resources. NTFPs play a significant role in improving rural livelihoods in India, as well as providing a valuable source of employment for rural residents, though it has a complex marketing system.

Abstract

Gunung Walat University Forest (GWUF) in Sukabumi Regency, Indonesia, plays a crucial role in providing various ecosystem services. Five important Shorea trees, i.e., S. stenoptera, S. mecisopteryx, S. pinanga, S. palembanica, and Shorea leprosula have been planted in GWUF as an effort for its conservation and object of research. An evaluation of the adaptability and suitability of these species to the GWUF ecosystem, as well as their wood characteristics, needs to be carried out regularly. Therefore, the study aimed to examine the growth performances and physical wood properties of five Shorea species, i.e., Shorea stenoptera, S. mecisopteryx, S. pinanga, S. palembanica, and S. leprosula at the age of 15-year-old planted in GWUF. The results indicated that S. leprosula exhibited the best growth performance in terms of average diameter (19.64 cm), volume (0.27 m3), slenderness (126.58), and wood density (0.94 g/cm3), and S. stenoptera showed the best performance in average height (23.35 m). While the poor performance was shown by S. palembanica in terms of average diameter (6.73 cm), height (11.15 m), volume (0.02 m3), wood density (0.87 g/cm3), and specific gravity (0.45), and S. stenoptera in terms of average slenderness (202.73). In addition, significant differences in tree height, diameter, volume, wood density, specific gravity, and moisture content were found in S. palembanica compared with other species. The relationship between the growth and physical wood properties parameters varied between species. The study revealed that planting the five Shorea species in GWUF is suitable for increasing vegetation cover and conserving the species.

Abstract

Lignocellulose materials, such as bamboo, rattan, and wood, have been largely used for furniture and crafts. On the other hand, the utilization of lignocellulose-like materials, which have a similar texture and appearance to those from nature, has been increasing recently due to their superior durability. This research aimed to identify the lignocellulose-like material using spectroscopy analysis, such as Raman and Near Infrared (NIR) which is well-known as a non-destructive, quick, and accurate approach for material identification. We investigated 4 types of lignocellulose-like materials that were provided by Dewan Serat Indonesia (The Indonesian Fiber Council) from an industry that produces them. The NIR analysis was performed at wavenumbers 10,000-4,000 cm-1. The natural lignocellulose (bamboo and wood) and the polymers (polyethylene and polyproline) were used as standards. Raman analysis was further employed to identify the composition of selected lignocellulose-like materials by comparing their spectra with the library software. The results showed that the original NIR spectra of lignocellulose-like and those natural materials were different, indicating that the NIR analysis can differentiate those materials. The NIR spectra of lignocellulose-like materials were similar to those of polyethylene spectra. Those lignocellulose-like were also identified as polyethylene due to the similarity of the Raman spectra and their library spectra.

Abstract

Ebony is one of slow-growing spe- cies), that of suspected to be the triggering factors to prone to extinction. In addition, the nature of ebony seeds is recalcitrant, so they cannot be stored for a long time. Other factors affecting seed germination are the degree of maturity, size, and weight of the seeds. Seeds harvested before the physiological maturity level would not have high viability and even could not germinate well due to the in-sufficient of food reserves, and un-perfect embryo formatio. Bio-fertilizer is used to help accelerate the growth of ebony. This study aims to analyze the combination of bio fertilizers which would be giving a better effect on the physiological activity and growth of ebony seedlings. Morphological and physiological variables measurement were used in this study. The research design used a Completely Randomized Design at a real level of 5%. If the fingerprint results obtained have a real effect, then a further test of the Duncan Multiple Range Test is carried out. Re- search results showed that seed coating treatment of 45% Penicillium microbial solution + seed coating) gave the best results in each variable of both growth and physiology of ebony seedlings, while in the treatment without seed coating, Sargassum microbial solution 30% indicates good results in each variable of growth and physiology of ebony seedlings. Treatment with the immersion of seeds in microbes can produce a high percentage in each variable.
