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

The COVID-19 pandemic has brought attention to the need for Indonesia to prepare for future food challenges. The government is focusing on developing underdeveloped areas, including peatlands, which have great potential for integrated farming systems. Bangsal is a village with peat swamp lands that serve as a source of food in OKI Regency, South Sumatera. During the dry season, the land is used for agriculture, while during the rainy season, it is used for fisheries. This paper analyzes (a) the village-based farming patterns in peatland areas, (b) the institutional framework of peatland farmer groups in Bangsal, and (c) the strategy for sustainable peatland utilization for food security. The study used both qualitative and quantitative data analysis methods. The research showed that the role of the Ulak Kuto Mandiri effectively and efficiently increased community income and food self-sufficiency. Integrated farming systems, including swamp buffalo farming, swamp fish farming, and swamp agriculture, optimally and sustainably increased the potential of peatlands. Sustainable peatland utilization through integrated farming systems technically preserves the peatland ecosystem from land conversion, is economically feasible, increases the income of farmers, livestock breeders, and local cultural traditions, and empowers women in farming activities. It also reduces forest fire risks, chemical fertilizer and pesticide use, and increases peatland productivity.

Abstract

To find a lasting solution to the problem of suitable fibre for pulp and papermaking in Nigeria, fibre suitability indices of nineteen wood species native to the rainforest zone of Nigeria were evaluated. Matured stems of the species were sourced and prepared for maceration. The fibre characteristics of the wood were carried out following ASTM D-1030-95 and ASTM D-1413-61. The fibres obtained were observed with the aid of a microscope and measurements of their morphology were done. A minimum of 25 fibres were measured for each species for accuracy. Selected morphological indices such as Runkel Ratio (RR), Flexibility Coefficient (FC), Slenderness Ratio (SR) as well as Rigidity Coefficient (RC) of the wood fibres were estimated. The results showed that the fibres lenght fall under short (1.05–1.36), medium-long (1.52–1.75), and long (2.0 mm) fibres criteria. All derived morphological indices showed significant variations from species to species. All fibres are not rigid and exhibited good SR with moderate rigidity and good felting power. They were all elastic; R. heudolotii and P. macrocarpa exhibited high elastic nature. They all have FC ≥ 50 and pass the RR ≤ 1, acceptable value for paper-making fibre except P. biglobosa and M. excelsa. The flexibility coefficients are in the range of 0.50 and 0.81. All the species pass the SR >33 acceptable value for paper-making fibres. The species if harnessed as fibre blends in pulp and paper making furnish will help to solve the problem of inadequate long fibres for paper production in Nigerian pulp mills.

Abstract

Currently, ecotourism has become an important industry because of its rapid development. Many tourism practices have adverse environmental impacts. Due to the increasingly destructive commercialization of the natural resources on which we depend, there are several negative impacts. Aek Nauli Research Forest (ANRF), with an area of 1,900 hectares, is one of the natural tourist destinations around the Lake Toba Tourism area managed by the Aek Nauli Research Institute for Environmental and Forestry Development (BP2LHK). The location of the study is in Girsang District, Sipangan Bolon, Simalungun Regency, North Sumatera Province. The tourist objects are natural panorama, elephant conservation education tour, and siamang animal ape park. On average, the number of visitors of ANRF on regular days is 100-300 visitors/day and on holidays reaches 300-1,700 visitors/day. The increase in the number of visitors is perceived to have an impact on environmental sustainability. This study aims to determine the capacity of the ANRF ecotourism area to accommodate the number of tourists per day simultaneously. The method used is the effective carrying capacity by Cifuentes method based on several stages of analysis, namely Physical Capacity (PCC), Real Capacity (RCC), Management Capacity (MC), and Effective Capacity (ECC). The environmental carrying capacity analysis results showed that the PCC, RCC, ECC were 26,106 visitors/day, 3,007 visitors/day, 2,505 visitors/day respectively while MC was 0.83. This value can be used to advise managers to limit visitors, particularly during peak season, in order to preserve objects and the quality of visits.

Abstract

Indonesia has a natural tourist attraction in the form of 54 national parks spread across regencies and cities, with an area of 16,304,707.13 hectares, featuring a diversity of ecosystems, high mountains, lowlands, savannahs to wetlands, and waters. However, the appeal of natural tourism does not necessarily contribute to the performance of national tourism, hence studies need to support of increase in tourist arrivals to national parks, one of which is to study tourism competitiveness in areas that have national parks in Indonesia. This research aims to develop a model of tourism competitiveness management in areas that have national parks in Indonesia. The theory underlying this research is the theory of tourism competitiveness through the approach of the competitiveness index of the Travel & Tourism Competitiveness Index, Indicators for Measuring Competitiveness in Tourism, and Competitiveness Monitor. The research design uses 20 competitiveness factors, where data collection techniques utilize data that has been available at both government and non-government institutions and the data collection method uses library research. The data were analysed by using the dynamic model method. The results of the study found that tourist arrivals significantly correlated simultaneously with the factor of tourism competitiveness of the districts and cities that have national parks, tourist arrival, revenue tourism, and conservation in zona utility of national park in Indonesia. It is proposed that local governments, national parks management and other interested parties make policy innovations to optimize the factors of tourism competitiveness in their regions to support or increase in the number of tourist visits in national parks

Abstract

Rattan in Indonesia is traditionally utilized for furniture, binding materials, household appliances, and handicraft items. Small diameter rattans are commonly used by craftsmen, while large diameter rattans are not optimally utilized. Large diameter rattan, however, has potential to be developed into rattan laminated board (RLB) by gluing rattan strips using appropriate adhesive. Nevertheless, the information of the suitable natural adhesive for RLB production is still limited. Laboratory scale of RLBs with the dimensions of 60 cm x 7.5 cm x 1.5 cm were manufactured using batang rattan strips (Calamus zollingeri Becc.). The strips were glued with six types of adhesives (4 types of natural adhesives and 2 types of commercial synthetic adhesives) and three glue spread rates of (100, 150, and 200 g/m2) were used. The study objective was to determine the effect of rattan pre-treatments, adhesive types and glue spread rates on the bonding quality and formaldehyde emission of RLBs. The results showed that batang rattan can be processed into RLBs by using natural adhesives originating from wood bark extract (mangium, mahogany), merbau wood powder, as well as commercial synthetic adhesives such as isocyanate and polyurethane. The appropriate pre-treatment in producing RLBs for interior furniture was by applying oil heat treatment with kerosene solution (80 kerosene : 20 water) and glued with tannin adhesive of mangium bark extract with glue spread of 200 g/m2. Similarly, rattan strips treated with heated oil (80 kerosene : 20 water) and glued with polyurethane adhesive (glue spread of 200 g/m2) produced excellent RLBs for exterior furniture.

Abstract

The coronavirus outbreak (COVID-19) has raised questions about changes in subsequent environmental effects, mainly forest and land fires. This paper evaluates the implementation of land and forest fire management policies in Indonesia during the COVID-19 pandemic, particularly in 2020. A qualitative approach was conducted in policy implementation analysis based on George Edward III's theory by looking at bureaucratic structure, resources, communication, and disposition factors. The research focused on the operational work of the Forest and Land Fire Brigade, known as Manggala Agni, in Indonesia. The results showed that the collaborative work of Manggala Agni and the other forest and land fire task forces successfully reduced the hotspots; hence there was a significant decrease in the burned area. It is also inseparable from climatic factors. During this period there was no haze disaster although the task of controlling forest and land fires still encountered several obstacles during the pandemic. This is because of training, technology transfer, budget support, and synergy between stakeholders and Manggala Agni’s team members, so a significant reduction in forest and land fires during 2020 can be achieved.

Abstract

The floristic study is necessary to understand the present diversity status and conservation of forest biodiversity. It has been realized that the study of local or regional flora is of much more significance than those covering big areas because explorations can be carried out intensively in small areas with damaging consequences. Understanding species diversity and distribution patterns are important to evaluate the complexity and resources of these forests. In the present study, the medicinal floristic diversity of Pilavakkal dam Foothills of the Western Ghats comprised of 127 species belonging to 42 families and 100 genera. Fabaceae, Malvaceae and Lamiaceae were dominant families with 23, 11 and 10 species, respectively. The total number of species includes 55 herbs, 23 shrubs, 37 trees and 12 climbers. Totally 127 important medicinal plant species are recorded in Pilavakkal dam Foot Slopes of Western Ghats. Psydrax dicoccos is vulnerable in this list, 27 plants species are Least Concern and Mangifera indica comes under the Data Deficient and 98 plants species evaluated are not categorized by IUCN. This study provides basic information about the medicinal flora and conservation status of the Pilavakkal dam Foothills of Western Ghats. It would also be helpful for the identification of flora and to derive conservation policies and make sustainable use of plant resources

Abstract

Goods and services of the ecosystem provided by the natural environment have not been considered in terms of their economic value. There are a number of studies that have estimated the economic value of forest ecosystem services in India, but very few studies have estimated these economic values of other important ecosystem services. Biligiri Rangaswamy Temple Wildlife Sanctuary (BRTWLS) is a unique place as a bridge between the Western Ghats and the Eastern Ghats in Karnataka, India. There are 12,500 Soligas (tribal community) living in this area. Non-timber forest products constitute more than 60% of the Soliga household income. A number of studies have been conducted in the BRTWLS. However, there is a lack of studies on the economic value. The primary objective of this study is to estimate the value of ecosystem services provided by BRTWLS. This study has used the market price methods for estimating the value of provisioning services and individual travel cost method for estimating the value of recreation services, while the value of carbon sequestration and soil erosion prevention has been estimated based on secondary data. This study has estimated the total annual value of provisioning, regulating and cultural services of BRTWLS at Rs 23.9 million y-1. The findings of the study will be helpful to the local policy makers to increase the entry fee at the BRTWLS, as it provides valuable ecosystem services and reinvests the same in natural capital to achieve environmental sustainability at the local level.

Abstract

Indonesia has abundant forest resources, reaching 120 million hectares of forest area. However, the forestry sector's contribution to the national economy continues to decline. The low performance of the forestry sector cannot be separated from the limited availability of round-wood materials for its processing industries and insufficient development of the multi-businesses activities among the forestry companies. Therefore, increasing the forestry sector's productivity is necessary through raising investment. This study investigates the impacts of investment in the forestry sector on Indonesian economic performance, including output, income, employment, and import, using the Input-Output (I-O) Model. The results show that investment in the forestry sector will increase output, income, and labour in the forestry sector and its related sectors. However, with the increase in its output, the demand for inputs, including round-wood materials, will also increase, encouraging a rise in imports. Thus, an increase in investment in the forestry sector needs to be balanced with the availability of roundwood materials and other associated inputs in Indonesia. For the follow-up research, it is important to separate the investment into upstream and downstream activities along the forestry value chain and include a regional aspect in the analysis.

Abstract

Forests have an important role in controlling soil erosion. Pine stands are considered effective in controlling erosion due to high interception and thick litter. This study compares the level of erosion on land with a slope > 40% to land with a slope <40%, as one of the references used in reviewing standards for determining the slope of a protected forest area. The study was conducted from November 2016 to February 2017, under Pinus merkusii stand in the Education Forest of Hasanuddin University in Maros Regency. Erosion was measured in a land of 22 m x 4 m having long slopes > 40% and < 40% with 3 replicates. Surface runoff was measured during rain and suspension levels was determined based on a dry oven heated at 105°C. Actual erosion (gr) is calculated by multiplying total runoff volume (m3/plot) by suspension level (gr/m3). The results show the average erosion on the slopes >40% was 54.94 g/plot or 0.006 tons/ha while on the slopes <40% was 36.74 g/plot or 0.004 tons/ha. The average difference of the two test results, with a 95% confidence interval, shows differences in the erosion average on the slopes> 40% and <40%. However, when there is an increase in the percentage of canopy cover the erosion becomes smaller even on the slopes > 40%. This research can be used as a reference for considering the increase in the upper limit of the slope of the protected forest area, and the need for further evaluation on the existing upper limit value.
