“…However, the wood harvested from its forest resources was still dominated by the Dipterocarpaceae family, commonly used for furniture and construction purposes. Although it had promising calorific values, it was considered a lowgrowing tree species that was not desirable for sustainable energy crops (Yuliansyah et al 2016). On the other hand, fast-growing tree species planted on forest plantations, such as Acacia mangium, Anthocephalus cadamba, Eucalyptus pellita, Gmelina arborea, and Paraserianthes falcataria, are have been reported to possess low heating value (Amirta et al 2016;Haqiqi et al 2022).…”

Abstract. Yuliansyah. Haqiqi MT, Setiawan KA, Setiawan A, Saputra PD, Romadlon HSI, Mukhdlor A, Ramadhan R, Amirta R. 2022. Fast-growing native tree species to the secondary forest of East Kalimantan, Indonesia: Physicochemical properties of woody materials for bioelectricity feedstocks. Biodiversitas 23: 3379-3386. The conversion of woody biomass into electricity through a thermochemical process has recently attracted significant attention worldwide to promote green energy production. It provides a low-cost and straightforward operation promising for developing rural areas, especially with limited transportation access. In East Kalimantan Province, almost all remote areas are surrounded by forests with high tree species diversity, which is the potential to be utilized for sustainable feedstocks in electric power plants. This study pointed out the energy potential produced from woody biomass of selected fast-growing tree species native to East Kalimantan secondary tropical forest: Elaeocarpus ferrugineus (Jacq.) Steud., Ficus aurata (Miq.) Miq., Fordia splendidissima (Blume ex Miq.) Buijsen, Lindera lucida (Blume) Boerl., Mallotus paniculatus (Lam.) Mull. Arg. and Schima wallichii (DC). Their wood physicochemical properties were firstly investigated. Furthermore, each species' wood quality for solid energy purposes was presented as the fuel value index (FVI). The results revealed that the change from greenwood into wood chip effectively removed the moisture content, thus improving efficiency to achieve higher energy potency. Our findings showed that the highest energy potency was obtained from the wood chip of F. splendidissima (3.61 MWh/ton), followed by S. wallichii (2.98 MWh/ton). A similar pattern was also found in FVI determination showing that the wood chip of S. Splendidissima had the greatest value (8970). Therefore, we observed that the high quality of S. splendidissima compared to other selected fast-growing species indicates its high suitability for further large-scale crop plantation to supply wood chips for biomass-based electricity generation.

Wood vinegar is a brown liquid by-product obtained from the carbonization process. Wood vinegar could limit the usage of wood vinegar as pesticide in acidic soil because of its acidity. This study aimed to determine the main organic and inorganic components in neutralized durian wood vinegar. Wood vinegar was made by pyrolisis of durian wood in the absence of oxygen with a temperature of 350, 450, and 550 °C for 2 hours. Before being analyzed, wood vinegar was neutralized with NaOH 25% to formulate the new friendly pesticide in an agricultural field. Characterization for acidity was by pH meter; organic compounds were using GC-MS; inorganic compounds were using AAS. The result showed that both neutralized wood vinegar and acidic wood vinegar indicated groups of organic acids, phenol and carbonyl compounds, which were suspected as pesticides. The predominant component in acidic wood vinegar was guaiacol, while in neutralized wood vinegar was pyrocatechol. Both acidic and neutralized wood vinegar indicatively contained main inorganic elements such as sodium, calcium, potassium, magnesium, iron and zinc that could serve as a natural pesticide. Based on the analysis result of inorganic elements, there were significant differences between acidic and neutralized wood vinegar except for Ca.
