“…The productivity of commercial E. pellita in Sumatra is around 16-18 m³/ha/year (Hardwood and Nambiar 2014). E. pellita wood has physical and chemical properties in the form of holocellulose content (75%), alpha-cellulose (49%), lignin content (29%), ethanol content (3.08%), and fiber length of 1.02 mm (Lukmandaru et al 2016) suitable as raw material for pulp and paper industry. E. pellita shows the characteristics of well growing and prominent wood characteristic compare to the other two species, namely E. grandis and E. urophylla (Prasetyo et al 2017).…”

Abstract. Prastyaningsih SR, Hardiwinoto S, Musyafa, Koranto CAD. 2020. Diversity of termites (Isoptera) on industrial forest plantation of Eucalyptus pellita stands of tropical ecosystem in Riau, Indonesia. Biodiversitas 21: 5498-5505. Eucalyptus pellita is an alternative tree species for pulp and paper of industrial forest plantation. One of the forest plantation’s negative effect is the loss of biodiversity and vulnerable to pest and disease. Termites are one of the pests attacking the forest plantations and play an important role in the ecological process. Need a better understanding of the termite role ecosystem process in E. pellita stands. This research aimed to determine the diversity of termite species found in E. pellita stands at different rotation and ages of stands. Termite diversity sampled by the transect sampling method in the 4th and 5th rotation with four-level ages (1, 2, 3, 4-years-old). The transect area was divided into 24 plots (100 m x 2 m). The termites in the Eucalyptus stand consist of two families (Termitidae and Rhinotermitidae), five subfamilies (Termitinae, Macrotermitinae, Nasutitermitinae, Rhinotermitinae, and Coptotermitinae), and eight species (Discupiditermes nemorosus, Macrotermes gilvus, Termes rostatus, Amitermes dentatus, Microcerotermes sp., Nasutitermes matangensis, Schedorhinotermes medioobscurus, and Coptotermes havilandi). The diversity index (H) in the 4th rotation was 1.95, while in the 5th rotation was 1.63, with a similarity in the Sorensen Index of 87.71%. The existence of termites is dominated by the wood feeder group. The species richness of the termites at the two rotations increased with the increase of the stand age.. The relative abundance composition of termites in the 5th rotation, is higher than the 4th rotation. Termite occurrence was influenced by necromass, tree biomass, humidity, and temperature.

“…Laju pergantiannya mencapai 50.000 ha/tahun dan pada tahun 2016-2017 sebanyak 600.000 ha lahan sudah ditanami E. pellita yang sebelumnya A. mangium (Nambiar, Harwood and Mendham, 2018). Pemilihan spesies E. pellita sebagai pengganti disebabkan oleh beberapa faktor, diantaranya: karena sifatnya yang cepat tumbuh, rotasi pendek, batang lurus, toleransi yang tinggi terhadap berbagai jenis tanah dan lokasi tumbuh serta lebih tahan terhadap hama dan penyakit (Lukmandaru et al, 2016). Namun demikian produktivitas E. pellita masih rendah dibandingkan dengan A. mangium.…”

Industri pulp Indonesia saat ini memiliki masalah dalam penyediaan bahan baku kayu Acacia mangium, karena serangan penyakit tanaman dan hama. Hal ini harus diantisipasi melalui bahan baku alternatif pengganti Acacia mangium, spesies Eucalyptus pellita dipilih karena lebih tahan terhadap hama dan penyakit. Penelitian ini dilakukan untuk mengetahui karakteristik kualitas pulp kraft putih E. Pellita. Penelitian pembuatan pulp kertas dilakukan dengan proses kraft dengan bahan baku A. mangium dan E. pellita. Pemasakan dilakukan dengan variasi alkali aktif 16-20%, sulfiditas 28,7%, pada suhu 165 °C, rasio larutan pemasak terhadap kayu 3,5:1 dan faktor H 1.022. Pemutihan pulp dilakukan dengan proses ECF (Elemental Chlorine Free) dengan tahapan OD0EoD1. Karakteristik pulp kraft hasil pemasakan A. mangium lebih tinggi pada parameter rendemen tersaring, bilangan kappa dan viskositas dibandingkan dengan E. pellita. Penggunaan alkali aktif 16% pada pemasakan A. mangium lebih rendah dari E. pellita (18%), namun kualitasnya dapat memenuhi spesifikasi kualitas pulp kraft putih sesuai SNI 6107:2015 (Pulp Kraft Putih Kayu daun) pada parameter derajat giling, derajat putih dan sifat fisik. Karakteristik pulp kraft putih A. mangium lebih tinggi pada parameter derajat giling, derajat putih dan sifat fisik dibandingkan dengan E. pellita. Namun demikian E. pellita berpotensi untuk dikembangkan di Hutan Tanaman Industri sebagai bahan baku pulp.Effect of Active Alkali on Characteristic of Acacia mangium and Eucalyptus pellita Bleached Kraft PulpAbstractThe Indonesian pulp industry currently has problems in supplying Acacia mangium wood raw materials, due to plant disease and pest attacks. This could be anticipated through alternative raw materials to substitute Acacia mangium, the Eucalyptus pellita species chosen because it is more resistant to pests and diseases. This study was conducted to determine the quality characteristics of E. Pellita bleached kraft pulp. The research on making paper pulp using A. mangium and E. pellita was carried out by means of the kraft process. The cooking was carried out with a variation of 16-20% active alkali, 28.7% sulfidity, at a temperature of 165°C, a liquor to wood ratio of 3.5:1 and an H factor of 1.022. The bleaching of the pulp has been carried out using the ECF (Elemental Chlorine Free) process with the OD0EoD1 stage. Characteristics of kraft pulp from A. mangium cooking were higher in the screening yield, kappa number and viscosity compared to E. Pellita. The use of 16% active alkaline in cooking of A. mangium is lower than E. pellita (18%), but the quality can meet the quality specifications of white kraft pulp according to SNI 6107: 2015 (White Kraft Leaf Wood Pulp) on the parameters of milled degree, whiteness and properties. The characteristics of A. mangium white kraft pulp were higher in parameters of grind degree, whiteness and physical properties compared to E. pellita. However, E. pellita has the potential to be developed in Industrial Plantation Forests as raw material for pulp.

“…In recent decades, forestry plantation in Indonesia has become a large-scale industry producing timber and wood pulp on more than 5 million hectares. On mineral soils, these plantations are based on Eucalyptus pellita, as a source of pulp and paper products [2,3]. Eucalyptus pellita grows rapidly, with a straight stem, and has high tolerance to various soil types and high resistance to pests and diseases [4].…”

The growth of Eucalyptus pellita in forestry plantations requires attention to water requirements, especially in the initial growth phase from seedling to field-ready plant. In this study, actual evapotranspiration (ETa), crop coefficient (Kc), and the irrigation requirement of E. pellita were assessed during the nursery growth phase (day 40–142). The experimental set-up included lysimeters with different treatments in terms of plants, drainage, and soil conditions. Plant growth and water balance were monitored during June September 2018 in an open nursery area in Riau, Indonesia. ETa was determined by the water balance lysimeter method and potential (reference) evapotranspiration (ETo) was extracted based on the Penman-Monteith method (FAO/56). The results showed that the average Kc value for E. pellita at age 40–142 days is 0.79, which exceeds that reported for E. grandis. The recommended irrigation requirement varies depending on precipitation, from 70 mL/plant/day with no rainfall to zero at precipitation of >30 mm/day. This is the first study to assess water use in E. pellita growing in pots during the nursery phase, which provides guidance on irrigation requirements during their initial growth phase.
