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

Screw tree (Helicteres isora Linn.) known as kayu ules is a shrub species (Fam: Malvaceae) with 1.5–4 m in height and with multi-main trunks up to 9–12. In Indonesia, kayu ules has been used as a traditional medicine, known as jamu, and has been commercialized. In order to cultivate this species, vegetative propagation is likely promising compared to the generative propagation since seed viability is low and cannot be stored for long period. Nevertheless, there is a lack of information on which diameter classes, media types and light intensities would give the best result for vegetative propagation. This research aimed to obtain information on which diameter classes and media type suitable for kayu ules stem cutting propagation the light intensity degree for the growth of kayu ules seedlings. Three diameter classes and four media types were employed in a complete random design under the greenhouse environment. Three months old good quality vegetatively-propagated seedlings were transplanted under two light intensities (under transparent canopy and shading net). Result shows that considering diameter classes and media type in kayu ules stem cutting propagation, it had improved the survival of the stem cutting. Diameter class I was the best grown in media type 3 with 46.67 ± 12.2 % of survival rate, diameter class II was best grown in media type 2 with 38.67 ± 11.6 % of survival rate, whereas diameter class III was best grown in media type 4 with 52 ± 6.9 % of survival rate.

Abstract

Malapari (Pongamia pinnata) is a potential plant for biodiesel and has the ability to grow on marginal land. Malapari cultivation has not yet been carried out due to low economic value. Agroforestry crop patterns are expected to provide intermediate results so that people would be interested in planting malapari. Planting on coastal land requires the right technology to produce optimal growth. This study aims to determine the effect of malapari cropping patterns and evaluate biological fertilizer application in the seedling phase after planting in the field. The research uses a split plot design (Split Plot Design) with the main factors that are the pattern of malapari planting and sub-plots that are the type of application of biofertilizer. The results obtained from the study showed that the interaction of cropping pattern treatment and biofertilizer application did not give significant growth to malapari; the combination of the application of organic manure, Trichoderma spp. and mycorrhiza bio-fertilizers in the nursery yielded the largest malapari diameter growth after planting in the field at the age of 3 years.

Abstract

Habitat destruction, over exploitation, monoculture are major reasons for loss of primary forests in Himalaya. Tree population, composition and diversity particularly in the temperate Himalaya play a key role in the maintenance of many ecosystem services and natural biogeochemical cycles. The present study explores composition and regeneration status of tree species in a temperate mixed forest in Kyongnosla Alpine Sanctuary, East Sikkim, India. Two sites at an elevation range of 2800–3800 m were selected and 20 plots of 20 m × 20 m for trees, 80 plots of 5 m × 5 m for saplings, and 160 plots of 1 m × 1 m for seedlings were sampled to study the regeneration status. A total of 17 tree species belonging to 9 genera and 8 families were recorded of which Rhododendron was the most dominant genus with maximum number of species. All the phytosociological attributes, such as relative density, abundance and important value index were calculated. The average species richness of adult trees and saplings was 13.5± 0.7 and for seedlings it was 12.5 ± 0.07. The mean density of seedlings was 3609.77 ± 494.39 individuals ha-1, for saplings 1540 ± 113.13 individuals ha-1 and of mature trees 548.75 ± 8.83 individuals ha-1. Total basal area cover ranged from 36.61 to 40.35 m2 ha-1 for trees, from 1.54 to 1.71 m2 ha-1 for saplings. Fair regeneration was observed in 64.72% of total species; good regeneration observed in 17.64% species, 11.76% species exhibited poor regeneration while 5.88% showed no regeneration.

Abstract

Post-coal mining areas need rehabilitation to restore its functionality. Not all plants could grow well on bare ex-coal mining area because of the excessive light intensity and extreme temperature fluctuations. This study is aimed to determine suitable local tree species for rehabilitating mined areas. Planting was carried out in November 2012, and observations were made in November 2015. The study site was in the district of Samboja, Kutai Kartanegara, East Kalimantan Province, Indonesia. Research results revealed that seven tree species survived well in the ex-coal mining land, i.e., Vitex pinnata L., Syzygium scortechinii (Merr.) Merr. & Perry, Syzygium polyanthum (Wight) Walp., Shorea balangeran (Korth.) Burck, Macaranga motleyana (Mull.Arg.) Mull.Arg., Cleistanthus myrianthus (Hassk.) Kurz and Syzygium lineatum (DC.) Merr. & L.M. Perry. From the seven species V. pinnata, Sy. scortechinii and Sy. polyanthum performed best in both survival and growth rates. This study suggests those three species are excellent local tree species for ex-coal mining rehabilitation, not only because of their high survival rate (≥80%) and fast-growing but also they produce favourable fruits and flowers for wildlife.

Abstract

Urban tree canopy within a university boundary is a measure of the university's tree cover as a percentage of its total land area. The overall objective of the present study is to conduct a Spatio-temporal change analysis of urban tree canopy in Nnamdi Azikiwe University Awka-Nigeria. Landsat data of years 1991, 2001, 2011 and 2019 were analysed using Maximum Likelihood Classifier and Confusion Matrix Spatial Analyst in ArcGIS 10.7.1 software. In terms of tree cover loss, there is a steady rate of decrease from -31.59 Hectares (ha) between 1991 and 2001; -82.32 ha (2001/2011) and -64.53 ha (2011/2019). Whereas, at an initial land area of 9.40 ha in 1991, physical infrastructural development is progressively increased with 16.92 ha between 1991 and 2001; 43.79 ha 2001/2011 and 12.37 ha between 2011 and 2019. The dominant drivers of tree cover change in the study area related to the expansion of physical infrastructures and sprawling agriculture as a result of encroachers into the study area. In conclusion, tropical forests within university campuses face many threats, such as those posed by unregulated physical infrastructural development and a lack of investment and management of forest relics. As a recommendation, Nigerian universities should invest and conserve their existing forested landscapes towards promoting land resources in line with Sustainable Development Goals number 15 (SDG-15) strategies.

Abstract

Cempaka wasian is a type of woody tree which has a substantial historical value associated with the local culture of the Minahasan people. The improvement of cempaka wasian plantation is essential due to their enormous importance and usage. This study aims to discover the impacts of duration, storage room, and containers used for the appropriate storage of cempaka wasian seeds. The design used in this study is entirely randomized design organized with a factorial pattern which consists of 3 factors; 1) storage duration, 2) storage room and 3) storage containers. Duration of storage was 2, 3, 4, and 5 months; meanwhile, storage rooms comprised of refrigerators, chambers, and air-conditioned room. Moreover, storing containers consisted of calico cloth, aluminium foils, and plastic bags. The study finding indicates that the seeds of cempaka wasian could still germinate if stored for five months by using plastics bags inside refrigerators. A significant provision of seeds and suitable timing are closely related to the proper seed storage techniques.

Abstract

The "tasty" cuisine tends to use chemical flavour agent containing monosodium glutamate (M.S.G.). M.S.G. utilizations, in long-term, may cause health problems, especially triggering cancer cells. Therefore necessary to introducing and increasing a natural flavouring agent to eliminate those health problem, such as bekai leaf. Bekai (Pycnarrhena tumefacta Miers) is familiar as a natural flavour agent (bio-vetsin) in cuisine for forest communities in Nyapa Indah Village, Berau, East Kalimantan, Indonesia. However, until now there has been no proper analysis support for widespread utilization of bekai leaf. This paper studies the presence of phytochemicals, antioxidant and GC MS analysis from bekai leaf extracts, as well as five hedonic classifications of organoleptic test, to reinforce the need for a better understanding of consumers reaction in terms of possible acceptance of additional bekai leaves applied in soup as bio-vetsin. Present study showed that the qualitative screening of phytochemical compounds in bekai leaves ethanolic extracts revealed presence of alkaloids, flavonoids, tannins and steroids. Antioxidants of bekai leaves using 2,2-diphenyl-1-picrylhydrazy (DPPH) method showed that concentrated extract has 80.1%, which predicted can improve immune for inhibitory action of cancer cells. GC MS analysis suspected that bekai leaf extract contained 5 (five) major compounds, i.e. oxirane dodecyl, gamma sitosterol, vitamin E (α tokoferol), 9.12-Octadecadienoic acid (Z,Z)- (natural linoleic acid), and 3-Tetradecanynoic acid (myristic acid). These chemical compound in related with their phytochemical were predicted to contained strong antioxidant activities and some of them commonly used as flavour agent in cuisine for some food industries.

Abstract

Invasion by alien plants has a detrimental effect on the natural forest plant community, leading to the loss of native species. An inventory of alien plants facilitates in determining the potential threats to the natural plant biodiversity. This present paper evaluates the alien plants in Mizoram (an Indo-Burma hotspot region) and provides the first authentic inventory of alien plants of Mizoram along with their diversity, ecological aspects, origin, and status of invasion. Extensive field surveys were done during July 2018 to September 2019 in different protected areas of Mizoram. We adopted Random Sampling Technique using nested quadrats in a plot size of 400 m2 (20 m × 20 m), within which a quadrate size of 5 m × 5 m was laid for shrubs and 1 m × 1 m was laid for herbs. Plant specimens were collected, dried, poisoned with 0.1% Mercuric Chloride (MgCl2); voucher specimens were prepared and deposited in Central National Herbarium, Botanical Survey of India (CAL) after proper identification.The results revealed the occurrence of 163 alien plant species under 135 genera belonging to 51 families in Mizoram. Maximum species were represented by family Asteraceae with 29 species followed by Leguminosae (19 species), Convolvulaceae (9 species), Euphorbiaceae (7 species) and Amaranthaceae (7 species). The 57.66% of the alien species reported from Mizoram were of American origin followed by 11.65 % from African, 7.36% from Mexican and 5.52% from Australian origin. Life form analysis revealed the presence of 58.64 % herbs, 15.43 % trees and 9.87% shrubs.

Abstract

Porang (konjac) plants have long been used as a food source and traditional medicine. Glucomannan derived from porang has been utilised for various uses such as antidiabetic and antihypercholesterolemia agent. This paper studies the mixture of porang flour and nano activated-carbon and its effect on the cholesterol activity of rats. The mixture of porang and activated carbon were subjected to test for male Sprague Dawley rats to test the antihypercholesterolemia activity. The result showed that concerted anticholesterol activity of porang and nano activated-carbon revealed the cholesterol level decreases in rat's blood. However, the different treatments of unleached and leached porang either leached porang and nano activated-carbon applied in the experiments showed that the levels of cholesterol decrease were slightly different (16–18%). Low glucomannan content as the alleged anticholesterol agent was regarded quite effective in lowering the cholesterol level in rat's blood and comparable with those of simvastatin which achieved 18% reduction. Therefore, it indicates potential utilisation as a functional food for a cholesterol-lowering agent. The involvement of activated carbon in the alleged anticholesterol agent (leached porang flour) did little in enhancing the cholesterol level decrease in rat's blood. The glucomannan in both leached porang flour and leached porang flour + nano activated-carbon shows potential utilisation as an anticholesterol agent. Yet, raw (unleached) porang is prospectively potential as a functional food for cholesterol-lowering.

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.
