“…However, even though it contained the highest calorific value, the energy production in the foliage was considerably lower than stem since it had a lower accumulation of biomass. Many studies published energy production of tree species was quantified by considering the calorific value and biomass (Magnago et al, 2016;Simetti et al, 2018;Visser et al, 2020). Besides improving carbon storage, higher biomass also increased the potential of energy in tree species.…”

The development of Eucalyptus urophylla in dryland ecosystems plays an important contribution to support climate change mitigation and renewable energy diversification. However, the information about the potential of E. urophylla for carbon reduction and energy production is rarely documented, even though it is necessary as fundamental considerations to determine the best strategy for sustainable natural resources management, primarily in dryland ecosystems. This study aimed to quantify the carbon storage and energy production of E. urophylla established in dryland ecosystems at East Nusa Tenggara. The study site is located in a eucalyptus plantation managed by Timor Tengah Selatan Forest Management Unit. Destructive sampling was conducted on 25 sample trees that were evenly distributed from small to big ones. The percentage of carbon content in every tree component, namely stem, branch, and foliage, was determined using elemental analysis, while the calorific value of each tree component was analyzed using a bomb calorimeter. Carbon storage in each component was calculated by multiplying biomass and the percentage of carbon content, while the energy production was computed by multiplying high heating value and biomass from every tree component. The results found the mean carbon storage of E. urophylla in the study site was 55.51 kg tree-1 with a minimum of 6.34 kg tree-1 and a maximum of 184.76 kg tree-1. The percentage of carbon content in the foliage was lower than other tree components by approximately 34.1%. Interestingly, the calorific value of foliage was relatively higher than stem and branch with around 5,252 kcal kg-1. The energy production of E. urophylla ranged from 252.6 to 7,813.3 MJ tree-1 with an average of 2,357.87 MJ tree-1. According to the results, this study concluded the development of E. urophylla in dryland ecosystems demonstrated a meaningful contribution to carbon absorption and energy production at East Nusa Tenggara.

“…Overall, they were higher in Tibagi-PR and lower in Itaberá-SP, with values between 17.2 and 18.4 MJ kg -1 . These values are slightly lower than those of eucalyptus, from 19.3 to 20 MJ kg -1 (GUERRA et al, 2014;SIMETTI et al, 2018), and close to those observed in other materials such as sugarcane bagasse, from 17.9 MJ kg -1 to 19.4 MJ kg -1 (PAULA et al, 2011;CORREIA et al, 2020), soybean stem and pod residues, from 16.47 to 18.20 MJ kg -1 (PAULA et al, 2011;PIERRI et al, 2019) and white oat straw, from 17.9 to 18.0 MJ kg -1 (GARCÍA et al, 2012;PIERRI et al, 2019).…”

Biomass produced in agricultural areas stores energy that can be used, contributing to regional development. Among the widely cultivated agricultural species is oats, destined for the production of not only grains and forage, but also biomass. The objective of this study was to characterize oat biomass in terms of the potential for energy generation considering the genetic and cultivation environment variability. Four field experiments were conducted in the state of Paraná and one in the state of São Paulo, Brazil, with black oat (Avena strigosa) and white oat (Avena sativa) cultivars. At the milky grain stage, plants were collected to quantify the production of shoot biomass and its qualitative variables for energy production and energy potential. Biomass yield varied between cultivars and cultivation sites. The mean higher calorific value was 17.9 MJ Kg-1, varying more between cultivation sites than between cultivars, being inversely proportional to the ash content. The contents of carbon, fixed carbon, volatile materials and nitrogen in the biomass did not vary between oat cultivars. The power generation potential varied widely between cultivars and cultivation sites, from 1557 to 3091 KWh ha-1, influenced mainly by the biomass yield, which overlaps the effects of the variations found in biomass quality. We concluded that oats are a species with high potential for use as an energy product, and the selection of the most productive cultivars regionally is crucial.

“…Therefore, the previous studies also report that the existence of eucalyptus plantations provides a significant contribution to climate change mitigation (Magalhães et al 2020). Furthermore, a study explains that eucalyptus wood can become a potential source of renewable energy since it has a high calorific value of 4,532-4,661 kcal kg -1 (Simetti et al 2018). The use of eucalyptus wood for bioenergy has been conducted in some foreign countries, including Brazil, Spain, and Portugal, wherein the development of biomass power plants has been intensively managed (Barreiro & Tomé 2012;González-García et al 2016;Cavalett et al 2018).…”

Abstract. Wirabuana PYAP, Alam S, Matatula J, Harahap MM, Nugroho Y, Idris F, Meinata A, Sekar DA. 2021. The growth, aboveground biomass, crown development, and leaf characteristics of three Eucalyptus species at initial stage of planting in Jepara, Indonesia. Biodiversitas 22: 2859-2869. Industry development, climate change mitigation and renewable energy currently become the most essential challenge in tropical forest management, primarily in Indonesia. The existence of tropical forests is not only managed to maintain the stability of wood supply for commercial industries but also to reduce greenhouse gas emissions in the atmosphere and to generate energy alternatives from tree biomass. To answer this challenge, the development of fast-growing species like eucalyptus can become a good solution. However, the productivity of eucalyptus depends on its adaptability to the site condition. Therefore, understanding site-species interaction becomes the fundamental requirement before planted on a large scale. This study aimed to evaluate the initial performance of eucalyptus species developed in Jepara. An experiment consisted of three different eucalyptus species, i.e., E. alba, E. pellita, and E. urophylla, was established using a randomized complete block design. Sixteen parameters were selected to assess the eucalyptus performance, including survival, height, diameter, biomass accumulation (stem, branches, foliage, and total aboveground), crown length, crown radius, crown projection area, crown ratio, individual leaf area, individual leaf dry weight, specific leaf area, leaf mass area, and leaf area index. The comparison of the mean of tree attributes from each species was examined using ANOVA, followed by HSD Tukey. Results showed that all measured parameters indicated a significant difference among the three species (p<0.05), except for survival, foliage biomass, and crown ratio (p>0.05). The preliminary performance of E. pellita was relatively better than the other two species, mainly related to height (3.00±0.21 m), total aboveground biomass (49.86±3.60 kg ha-1), crown projection area (2.68±0.27 m2 ), and leaf area index (5.76±0.44). Our study concluded the initial performance of E. pellita in Jepara was substantially superior to E. alba and E. urophylla. Nevertheless, continuous evaluation is needed to monitor the consistent performance of those species in the study area.
