“…Nevertheless, machine 4 (feller-chipper that worked only in SRC-plantation with a medium-length rotation) showed a low working rate because its working process was not continuous due to difficulty in cutting trees with large diameters (up to 400 mm). In fact, under these conditions, manual cutting and harvesting can be economically competitive compared to mechanical systems [64].…”

“…However, only a little information about fast growing and short rotation coppice wood biomass plant species from swamp-peat forests, including their energy potency, is available so far. Most of the information of energy plant species were reported from the lowland forest areas, such as Willow (Salix viminalis), Poplar (Populus trichocarpa),_ Black Locust (Robinia pseudoacacia), and also Acacia (Acacia melanoxylon) and Eucalyptus (Eucalyptus globulus) trees, commonly used in Denmark, Germany, Poland, Italy, New Zealand and other European countries (Sims et al 2001;Sims and Venturi 2004;Fiala and Bacenetti 2012;Dillen et al 2013;Ghaley and Porter 2014;Hauk et al 2014;Haverkamp and Musshoff 2014;Krzyzaniak et al 2015;Niemczyk et al 2018). Similar situation exists in Indonesia forest energy sector where very limited number of plant species, such as Calliandra calothyrsus, Glyricidia sepium, Macaranga hypoleuca and Vitex pinnata are known as the energy feedstock (Amirta et al 2016a;2016b).…”

Abstract. Amirta R, Haqiqi MT, Saparwadi, Septia E, Mujiasih D, Setiawan KA, Sekedang MA, Yuliansyah, Wijaya A, Setiyono B, Suwinarti W. 2019. Searching for potential wood biomass for green energy feedstock: A study in tropical swamp-peat forest of Kutai Kertanegara, Indonesia. Biodiversitas 20: 1516-1523. Recently, much attention has been focused on finding suitable plant species, from different forest ecosystems, having the potential to be used as sources of renewable energy. Most of such information was reported from the lowland forest area and only limited information is available regarding swamp-peat forest species, including their energy potency. Therefore, in this paper, plant diversity and energy potency of swamp-peat forest wood biomass were studied to reveal their potential as green energy feedstock. Physico-chemical characterization of wood biomass was performed using the American Society for Testing and Material (ASTM) protocols. Twenty-seven species of plants, consisting of 23 trees and 4 shrubs, belonging to 19 families were identified, amongst which Shorea balangeran had the highest importance value index (87.72%). The results showed that T. obovata exhibit the highest suitability to be used as energy feedstock indicated by the highest energy production of 4.60 MWh per ton of dry biomass, followed by L. indica (4.56 MWh/ton), D. excelsa (5.52 MWh/ton), F. rukam (4.20 MWh/ton), P. galeata (3.66 MWh/ton), S. caudatilimbum (3.61 MWh/ton), A. elmeri (3.59 MWh/ton), G. nervosa (3.49 MWh/ton) and G. bancana (3.42 MWh/ton). The high density of wood species correlated with the high value of energy potency. In contrast, the fast-growing tree and shrub species, such as K. hospita (1.76 MWh/ton), C. odorata (1.36 MWh/ton) and O. sumatrana (1.17 MWh/ton), showed lower energy potency. The most dominant plant species, S. balangeran gave only 2.96 MWh energy per ton of dry biomass and it was classified in the middle group of plant species suitable as green energy feedstock, along with other species, such as C. brachiata, C. rotundatus, P. javanicum, V. umbonata, L. speciosa, V. pinnata, and A. longifolius. Due to suitable energy properties, growth rate and also adaptability of this woody biomass, they can be exploited to support sustainable supply of biomass feedstock for the green electricity program in the study area.

“…Agricultural crops, plant residues, forest resources and special energy plants are common biomass sources to produce energy (Avcıoglu et al 2019). The shrub species are also reported as good potential feedstock to provide sustainable energy (Dillen et al 2013;Ghaley and Porter 2014;Hauk et al 2014;Haverkamp and Musshoff 2014;Pérez et al 2014;Krzyzaniak et al 2015;Niemczyk et al 2018;Gonzalez-Gonzalez et al 2017;Amirta et al 2016a;Martinez et al 2019). On the other hand, investigation about unutilized biomass sources such as agricultural waste shows great promise as an alternative to cheap raw material.…”

Abstract. Yuliansyah, Haqiqi MT, Septia E, Mujiasih D, Septiana HA, Setiawan KA, Setiyono B, Angi EM, Saparwadi, Sari NM, Kusuma IW, Rujehan, Suwinarti W, Amirta R. 2019. Short Communication: Diversity of plant species growing during fallow period of shifting cultivation and potential of its biomass for sustainable energy production in Mahakam Ulu, East Kalimantan, Indonesia. Biodiversitas 20: 2236-2242. Fallow period is a time gap, as long as 15 years, for improving natural soil fertility of land used for traditional shifting cultivation, in the tropical areas commonly used by Dayak People in Borneo Island. During this period, many biomass plant species naturally grow and develop a new forest vegetation community with shrub and medium trees, dominated by fast-growing pioneer species. In this study, we investigated the plant diversity in fallowed shifting cultivation area in Batu Majang Village, Mahakam Ulu District, East Kalimantan Province, followed by analysis of the suitability of wood characteristics for energy production. We classified the study area according to the age of fallow period as: 1-3 years, 4-6 years, 7-9 years and 10-15 years. We found 29 species among which 13 were identified as the top species according to the highest value for important value index. Potential wood biomass production increased from 3.01 m3 ha-1 to 399.62 m3 ha-1. V. pinnata and M. pearsonii showed the highest dominance which is present in almost all area based on age classification groups. Wood from V. pinnata achieved the highest calorific valueof18.00 MJ kg-1 whereas N. cadamba and M. sericea were in the second and third places with the value of 17.30 MJ kg-1 and 17.28 MJ kg-1, respectively. Therefore, V. pinnata was an important species among all other species observed because of high adaptability and high energy content. In addition, possible energy production at the end of the fallow period of 15 years was 2.92 GJ ha-1.
