ALLOMETRIC EQUATIONS FOR ESTIMATING ABOVEGROUND BIOMASS IN PAPUA TROPICAL FOREST
Authors: Maulana Sandhi Imam 
Published: January 2025

Allometric equations can be used to estimate biomass and carbon stock of the forest. However, so far the allometric equations for commercial species in Papua tropical forests have not been appropriately developed. In this research, allometric equations are presented based on the genera of commercial species. Few equations have been developed for the commercial species of Intsia, Pometia, Palaquium and Vatica genera and an equation of a mix of these genera. The number of trees sampled in this research was 49, with diameters (1.30 m above-ground or above buttresses) ranging from 5 to 40 cm. Destructive sampling was used to collect the samples where Diameter at Breast Height (DBH) and Wood Density (WD) were used as predictors for dry weight of Total Above-Ground Biomass (TAGB). Model comparison and selection were based on the values of F-statistics, R-sq, R-sq (adj), and average deviation. Based on these statistical indicators, the most suitable model for Intsia, Pometia, Palaquium and Vatica genera respectively are Log(TAGB) = -0.76 + 2.51Log(DBH), Log(TAGB) = -0.84 + 2.57Log(DBH), Log(TAGB) = -1.52 + 2.96Log(DBH), and Log(TAGB) = -0.09 + 2.08Log(DBH). Additional explanatory variables such as Commercial Bole Height (CBH) do not really increase the indicators’ goodness of fit for the equation. An alternative model to incorporate wood density should be considered for estimating the above-ground biomass for mixed genera.
LEAF AREA INDEX DERIVED FROM HEMISPHERICAL PHOTOGRAPH AND ITS CORRELATION WITH ABOVEGROUND FOREST BIOMASS
Authors: Basuki Tyas Mutiara 
Published: January 2025

Leaf area index (LAI) is one of the key physical factors in the energy exchange between terrestrial ecosystem and atmosphere. It determines the photosynthesis process to produce biomass and plays an important role in performing forest stand reflectance. Therefore building relationship between LAI and biomass from field measurements can be used to develop allometric equations for biomass estimation. This paper studies the relationship between diameter at breast height (DBH) and leaves biomass, DBH and crown biomass (sum up of leaves, twigs and branches) as well as between LAI and leaves biomass; LAI and crown biomass; LAI and Total Above-ground Biomass (TAGB) in East Kalimantan Province. Destructive sampling was conducted to develop allometric equations. The DBH measurements from 52 sample plots were used as training data for model development (35 plots) and for validation (17 plots). A hemispherical photograph was used to record LAI. The result shows that strong corelation (r) exists between natural logarithmic (ln) DBH and crown biomass ranging from 0.88 to 0.98. The correlation (r) between LAI and biomass of leaves; leaves + twigs + branches; TAGB were 0.742, 0.768 and 0.772, respectively. Improvement of (r) between LAI and biomass can be conducted by proper time of LAI measurement, when the sky is uniformly overcast.

Authors: Ayat Asep , Tata Hesti L. 
Published: January 2025

Birds play a pivotal role in ecosystems, but in disturbed areas their role may be limited due to changes in their habitat. In Simalungun and Asahan districts, North Sumatra, bird communities were studied in a range of habitats: natural forest, rubber agroforests (RAF), rubber monoculture plantations (RMP) and emplacement areas. The birds were observed using descriptive survey methods by implementing a quick biodiversity survey, with data collected along a 1km transect. In total, 142 species of birds from 42 families were found in the four habitats. Natural forests held the highest diversity of bird species, followed by rubber agroforests, emplacement areas and rubber plantations, with a Shannon-Wiener index of 4.5, 3.6, 3.6 and 3, respectively. Regarding the IUCN red list species, 12 bird species of near-threatened status and 2 species of vulnerable status were recorded. Based on CITES categories, one species was listed in the Appendix criteria I, 12 species were classified in Appendix II and 26 bird species were protected under Indonesian regulations. Changes in the structure and composition of vegetation in disturbed forests and cleared land determined the richness of bird species. The different tree compositions in the three habitats of the rubber estate plantations and surrounding areas influenced the number of bird species, their diversity and species composition.

Published: January 2025

Mangrove is a unique ecosystem that has complex biotic and abiotic components. Soil and water microorganisms have function as decomposer in mangrove forest ecosystem. This paper studies the soil and water microorganisms' diversity, their potential, function in ecosystem and their role as environmental parameters in mangrove area of Teluk Kelumpang, Selat Laut and Selat Sebuku Natural Reserve (Kelautku Natural Reserve). Data of soil and water microorganisms were recorded from soil and water samplings then analyzed in the laboratory. Results show that benthos in Selat Sebuku figure the highest diversity index. Anadara granosa is one of the common benthos found in Selat Sebuku. In contrary the phytoplankton in Selat Sebuku is the lowest value compared to the other two locations, due to the settlements in the locations and it was suspected that Selat Sebuku has a relatively larger wave exposure than the two other locations. In addition, input of organic matters from the settlements in Teluk Kelumpang and Selat Laut is also effected by the growth of phytoplankton. Cyanophyta found in Teluk Kelumpang and Selat Laut was genera of Oscillatoria that showed high tolerance genera to the environment conditions.

Published: January 2025

Two cycles breeding program of Acacia mangium was practiced by Center for Forest Biotechnology and Tree Improvement Research. Although improved seed from the breeding program have been used in operational plantation, the real amount of gains in productivity was not verified together yet. This study was aimed to observe realized genetic gain and projected increase in stand volume from the two cycles breeding of A. mangium, and to discuss the implications on plantation productivity and sustainable forestry in Indonesia. Improved seed from first and second-generation seed orchard were tested together with an unimproved seed in genetic gain trial in West Java, with spacing of 3 x 3 m. Measurements were done at three years ages for height, dbh, and stem volume. Realized genetic gain was calculated as the percentage increase of improved seed over the unimproved one. Results of study showed that improved seed performed better growth than the unimproved with realized gain of 5-24% (height), 3-44% (dbh) and 11-90% (stem volume). Improved seed from second-generation outperformed that from the first-generation, with an improvement of 6-16% (height), 3-26% (dbh) and 20-53% (stem volume). Genetic gains increased with increasing ages for height, but it tended to decrease for dbh and stem volume. At given site and silvicultural practices, projected increase in stand volume at 8 years rotation reached 290-325 m3/ha, which is equal to 30-50% of gains. The uses of high genetically improved seed, in combination with intensive silviculture, would provide significant impacts on plantation productivity and sustainable forestry in Indonesia.
SITE INDEX PREDICTION OF SMALLHOLDER PLANTATIONS OF KAYU BAWANG (Disoxylum mollissimum Blume) IN BENGKULU PROVINCE
Authors: Siahaan Hengki , Sumadi Agus 
Published: January 2025

Kayu bawang (Dysoxylum mollissimum Blume) has been planted almost in all districts of Bengkulu Province, Indonesia, but yet no study has been conducted to analyze the site quality of this species. This paper studies the site quality of Dysoxylum mollissimum Blume of smallholder plantations by establishing 32 permanent sample plots (PSPs) distributed in six districts of Bengkulu Province and measured periodically from 2006 to 2012. Site quality was determined by phytocentric method which used stand dominant height as a indicator. The result shows that the best model for dominant height growth of Dysoxylum mollissimum Blume in Bengkulu Province was the Schumacher model expressed by the equation: Ln Ho = (3.06 + ai) – 2.05/A (R2 = 96.5%, Absolute Mean Residual (AMRES) = 0.82 and Average Percentage Difference (APD) =5.03%). The relevant site equation for this species derived from the dominant height growth model was: Ln Si = Ln H0 – 2.05 (1/12-1/A) for an index age of 12 years. Based on this equation, the sites were classified into 5 classes having an equal range of 3 m i.e. SI < 16 m; 16 m = SI < 19 m; 19 m = SI < 22 m; 22 m = SI < 25 m; and SI = 25 m: for site classes I, II, III, IV, and V representing from the lowest to the highest productivity respectively.

Published: January 2025

Using current technologies, several forest plantation companies in Indonesia are pursuing clonal forestry program with E. pellita to increase plantation productivity using selected clones. This paper evaluates the early growth and stand volume productivity of selected clones of E. pellita as part of a breeding program for pulpwood. Two clonal trials of E. pellita were established in Central Java with two different plot configurations: single tree-plot and multiple tree-plot. Trial evaluation was done at two years age involving tree height, diameter, stem volume and stand volume. Result show that among the clones there were significant differences for all traits assessed. All of the tested clones exceeded the control seedling of F-1 generation by 9-50% for height, 10-36% for diameter and 22-137% for stem volume, respectively. Clonal repeatability ranged from 0.7-0.9, with corresponding individual ramet repeatability ranged from 0.2-0.4. Overall stand volume productivity at given age reached 15 m³/ha.
IMPACTS, PATTERNS, INFLUENCING FACTORS AND POLICIES OF FUELWOOD EXTRACTION IN WAY KAMBAS NATIONAL PARK, INDONESIA
Authors: Rakatama Ari 
Published: January 2025

Uncontrolled fuelwood extraction from conservation forest of Way Kambas National Park (WKNP) could threaten the existing forest. This paper studies the way to tackle the forest degradation in WKNP, with less negative impacts to the local people. Study was conducted by analysing existing data and maps of WKNP in terms of forest degradation, forest inventories, current policies, survey on how fuelwood is extracted, observation on fuelwood gatherers, fuelwood demand, and identification of further policy options. Results show that the most significant factors influencing the fuelwood extraction activity in WKNP are land ownership, followed by the distance to forest area, income level, the number of household members and age of household head. In the field, the fuelwood utilization is allowed by WKNP Authority, although it is formally forbidden.It was stated that fuelwood extraction in the area should be less than 2.89 ton/ha/year to maintain its sustainability, based on the mean WNKP forest tree annual increment. The fact shows that fuelwood extraction in WKNP reduces of forest biomass stock (1.06 tons/ha/year) and decreases species diversity index (from 3.05 to 2.45), species evenness index (from 1.06 to 0.91) and old-young tree ratio (from 1.29 to 1). Ecosystem quality reduction is mainly caused by destructive techniques in extracting fuelwood such as slashing, scratching cambium, and cutting trees.

La filosofía crítica realista postkantiana
Authors: Argañaraz Juan 
Published: January 2025

El trabajo expone la conjetura de que existió, durante los s. XIX y XX, una tradición, la Filosofía crítica realista, postkantiana y antiidealista, desdibujada en la historiografía por motivos que se indagan aquí. Realismo crítico (Herbart), empirismo crítico (Mach) y racionalismo crítico (Popper-Lakatos) serían eslabones de esta tradición. La aceptación provisional de tal hipótesis, genera una interesante reconsideración conceptual e historiográfica de la Filosofía general y especialmente de la Filosofía de la ciencia. Suponiendo cierta esta conjetura, divergencias conocidas entre autores - Helmholtz Popper sobre el inductivismo por ejemplo -, podrían releerse como discusiones internas a ella. Obras y autores que se critican entre sí, como Fleck a Mach o Lakatos a Popper, podrían considerarse ensayos para mejorar la racionalidad, el empirismo o el realismo críticos. El mismo “giro historicista” de Kuhn y Lakatos cobraría otro sentido, una ‘restauración historicista’ más que un giro - en la tradición de Goethe, Mach, Duhem, Fleck -, ya que la investigación historiográfica fue desatendida por el Círculo de Viena y Popper pero era programática en aquellos.
El “Giro Transnacional” y el “Giro Espacial” en la Historia de la Ciencia
Authors: Durán Maturana Yonatan 
Published: January 2025

The purpose of this paper is to present some “turns” (the transnational and the spatial) that emerged in the context of criticism of the traditional historiography of science; approaches structured by the idea of circulation which, incidentally, has become a resource of analysis by showing how science has been a process in which scientists from different latitudes have participated in a global process of circulation of scientific knowledge. The scheme I follow is this: in the first moment (sections 2 and 3) of a purely expository nature, I present the two “turns”, maintaining circulation as the common thread. In the second moment (section 4) I interpret them, proposing the circulation of scientific knowledge as the foundation of the supra-individual (if you will, collective) nature of scientific activity, while proposing a (generic) methodological scheme to study circulation in the sciences.
Simile and meaning sentences relating to "tree"
Authors: Chuluun Byambatsetseg 
Published: January 2025

When looking at the linguistic evidence for the metaphor "tree", there are cases where it is used to compare time, creatures and animals, writing instruments, and objects and organs made of wood. A tree consists of a stem, roots, branches, and twigs, and there are cases where objects are named by their hidden nature, as metaphors within the context of words that indicate their characteristics and appearance.
In the genre of oral storytelling, the positive value and attitude of the main characteristics of trees, such as growth and reproduction, and the importance of nature and ecology, are often repeated in magical tales as "guides", "symbols of growth", “sustainers of life", “worship of trees” and “analyzing through trees” define the environment of the metaphorical character of a tree.
