“…However, both Kawui and E. pellita are included in high holocellulose content. The α-cellulose content of Kawui wood increases from sapwood to heartwood, both are classified ‘medium.’ Moreover, the α-cellulose of Kawui is higher than E. pellita (Lukmandaru 2018), in which both sapwood and heartwood are included ‘low.’ Holocellulose and α-cellulose contents indicate the yield of pulp (Pari and dan Hartoyo 1990; Supartini 2009). The higher the cellulose content, the higher the yield of pulp is, and the higher the affinity of the solution, the brighter the yield of pulp is.…”

The anatomical and chemical properties of a lesser known species, Kawui wood, were investigated Two trees were examined based on IAWA, ASTM and SNI. A completely randomised design was used with radial direction of the trunk (sapwood and heartwood) as the factor, in three replications. It indicated the highest to lowest cell proportions are fibres, rays, vessels and parenchyma. The highest proportion of rays was in the sapwood, while the fibre was in the heartwood. However, the average fibre length in the sapwood was higher than the heartwood, while the lumen diameter showed the reverse. Holocellulose, αcellulose, lignin, extractives, and ash content of the sapwood was higher than the heartwood. Based on its anatomical and chemical properties, Kawui wood can be included in grade II-IV, which is suitable for medium quality pulp and paper production.

“…Lignin content of wood is considered to be high when reaching to >33% (Supartini 2009), and lignin content is a character that determines the quality of wood pellet (Peksa-Blanchard et al 2007). The importance of lignin content in biomass for energy has been very common.…”

To be viable, fast-growing energy plantations must be large in volume, harvested at early age, and maximized calorific value which linked to heartwood proportion. This study examines 38 families in the second generation (F ) 2 progeny trial of Acacia auriculiformis for energy. Heartwood proportion, calorific value and lignin content were assessed at ages 22, 30, 35, and 40 months. Wood samples from around 300 selected individuals of observed ages from all families were examined. Quality was based on heartwood and sapwood development until reaching the -1 commercial requirement of >33% for lignin content and >4,500 cal g for calorific value. When required quality has been obtained at particular age, assessment of biomass was carried out from all final individuals in the progeny test. Heartwood proportion varies among families. Heartwood possesses higher values than sapwood in lignin content and calorific value. Individuals with higher heartwood proportion are preferred. Both wood types only reached the required quality for solid wood energy after 3.5 years, however lignin content at much early age are appropriate for wood pellet and briquette. Selection improves heartwood proportion and quality from the first 3 -1 -1 generation (F ) into F with an increase of 52% at three years. Mean annual increments at 3.5 years is 43 m ha yr . 1 2

“…Kandungan holoselulosa dan selulosa tertinggi terdapat pada bagian tengah batang, sedangkan terkecil pada bagian ujung, tingginya kandungan holoselulosa dan selulosa pada bagian tengah batang diduga karena adanya perkembangan serat yang meningkat seiring dengan bertambahnya tinggi pohon hingga pada ketinggian tertentu kemudian menurun pada ujung batang (Supartini, 2009).…”

Wood of moon (Fagraea crenulata) and wood of mahang (Macaranga sp.) are not included the commercial timber species, therefore the knowledge regarding chemical properties of their woods are needed in order to provide information for various purposes according to their properties. The research was aimed to know chemical properties of moon wood and mahang wood. The research had been conducted at the laboratory of Forestry Department, University of Palangka Raya since February to March 2017. Research resultd showed that the solubility of moon and mahang woods in the cold water, hot water, 1% NaOH and alcohol benzene are classified as high. According chemical components analysis, their wood are not suitable for pul and paper, because they have some characteristic as follow: holoselulosa is poor, cellulose is low, hemicellulose is middle, and lignin is not good. Meanwhile, wood ash of moon and mahang are classified moderate (range of Indonesia chemical components of broadleaf wood is range start from 0.2 to 6%) with values of them are 0.654% for moon wood and 0.689% for mahang wood. With the result their woods are considered to wood energy utilization. Keywords: chemical component, mahang wood, moon wood, wood energy
