“…Degradation or decrease in hemicellulose during the heating process causes a visual color change, causing a decrease in L* (Salca et al, 2016). Color changes in biomass after exposure to high temperatures can be caused by changes in chemical composition (Hidayat et al, 2021). (4)…”

The objective of this study was to evaluate the effects of torrefaction temperature on the physical and mechanical properties of betung bamboo (Dendrocalamus asper) pellets. Torrefaction was conducted in an electric furnace at 200°C, 240°C, and 280°C for 50 minutes. The physical properties evaluated included color change, density, moisture content, water resistance, and water adsorption. The mechanical properties were also investigated by compressive strength test. The result showed that torrefaction affected the color properties of betung bamboo pellets with ∆E values of more than 12 or totally changed. The density and moisture content of torrefaction bamboo betung pellets decreased with increasing torrefaction temperature. The results also showed that the hydrophobic properties of the bamboo betung pellets improved with the increased of torrefaction temperature. The highest compressive strength value was obtained by bamboo betung pellets torrefied at 200°C and the values decreased with the increase of temperature. In conclusion, there were differences in the physical and mechanical properties of bamboo betung pellets that were torrefied at different temperatures. Torrefaction with an electric furnace effectively improved the quality of betung bamboo pellets. Keywords: Bamboo betung, pellets, temperature, torrefaction

“…Anthocephalus cadamba is one of the native Indonesian tree species that is suitable as a basis for plantation forests. It could be caused by Anthocephalus cadamba wood species having the potential to be developed and meet industrial needs [15]. However, Anthocephalus cadamba trees are included in the category of fast-growing wood species [16].…”

Anthocephalus cadamba wood exhibits considerable potential as a fast-growing wood species that can effectively address the issue of diminishing wood resources derived from natural forests. Nevertheless, it is important to note that wood derived from fast-growing species has substandard features compared to wood obtained from natural forests. So, it becomes imperative to enhance the quality of such wood by implementing heat treatment techniques. In addition, heat treatment of the wood is performed with a temperature in the range of 160-260℃, and the processing time is relatively short. Therefore, the purpose of this research was to evaluate the impact of air heat treatment on the dimensional stability, strength, and hardness of Anthocephalus cadamba wood. For 4 hours, Anthocephalus cadamba wood was heated to 170, 190, and 210℃. The CIE-Lab color system was used to analyze the wood's color transformation following treatment. Moisture content, density, weight changes, volume shrinkage, hardness, and compressive strength were also measured before and after treatment. Overall, color shift (E*) was shown to be mitigated by higher treatment temperatures. The extractive ingredients in Anthocephalus cadamba wood discolored slightly at 170 but entirely at 190 and 210℃. Weight loss, volume shrinkage, density, and moisture content were also seen in heattreated Anthocephalus cadamba wood. Polymer breakdown and water uptake by cell walls could be to blame. The dimensional stability of Anthocephalus cadamba wood was reduced along with its hydrophobicity. Wood's compressive strength decreases as hemicellulose is degraded during heat treatment and at higher temperatures. Reduced hardness is caused by high treatment temperatures and weight loss that weakens wood. As described, the color and dimensional stability of the heat-treated samples indicated as the effective parameters to improve in this present study. As air heat treatment temperatures rise owing to chemical compound degradation in Anthocephalus cadamba wood, its physical and mechanical qualities can change. In conclusion, this study showed the feasibility of heat treatment on Anthocephalus cadamba wood to improve the color dan dimensional stability.

Bamboo is an abundant biomaterial having important potential as a resource for bioenergy development. In this study, the potential of andong (Gigantochloa pseudoarundinacea (Steudel) Widjaja) bamboo for pellet production was evaluated. Some properties of bamboo pellets as density, moisture content, moisture adsorption, compressive strength, and heating value were analysed. The results indicated that bamboo is highly prospective to be explored for fuel pellets commercially. All characteristics of pellet made of bamboo fulfilled the requisites of the commercial pellets. The heating value of the pellets achieved the minimum standard for commercial pellets along with SNI 8675:2018 (>17,5 MJ/kg). The effects of culm parts on the moisture content, density, moisture adsorption were not significant. There were significant differences in compressive strength and heating value between bamboo pellets produced from different culm parts. This research showed potential of andong bamboo pellet for bioenergy resource. Keywords: Andong (Gigantochloa pseudoarundinacea), Biopellet, Mechanical Properties, Physical Properties
