“…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). Investment and expansion in Eucalyptus plantations and pulp mills is predicted to continue sustainably (Phillips 2013).…”

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.

“…In 9-year-old E. camaldulensis trees grown in Thailand, the basic density was 0.66 g/cm 3 (Veenin et al, 2005). For 9-year-old E. urophylla, E. grandis, and E. pellita trees planted in Indonesia, the mean values of the basic density were 0.46, 0.41, and 0.46 g/cm 3 , respectively (Prasetyo et al, 2017). Dickson et al (2003) reported that the basic density of 25-yearold E. dunnii trees planted in Vietnam was 0.60 g/cm 3 .…”

“…The mean values of stress-wave velocity in the present study was 3.44 km/s (Table 2). Several researchers have measured the stress-wave velocity of stems in Eucalyptus species at an age of approximately 10 years old or older (Blackburn et al, 2010;Wahyudi et al, 2015;Prasetyo et al, 2017). Blackburn et al (2010) reported that the stress-wave velocity of the stem ranged from 3.18 to 3.36 km/s in 14-year-old E. nitens trees planted in Australia.…”

To promote solid wood production, the diameter at breast height, height, stress-wave velocity, surface-released strain, basic density and compressive strength parallel to the grain were measured for 10 half-sib families of 12-year-old Eucalyptus camaldulensis Dehnh. trees growing in Thailand. Based on the results, growth rates, correlations among measured properties, radial and among-family variations of wood properties, and their repeatability were evaluated. Diameter at breast height, height, and wood volume were exponentially increased at initial stage, and then gradually increased toward to 12 years after planting. The maximum current annual increment and mean annual increment in wood volume showed at age of 8 and 11years old, suggesting that rotation period for optimum productivity may be ranged from 8 to 11 years old. Wood with stable properties was found greater than 6 cm from the pith. These results indicate that 12-year-old E. camaldulensis trees had already reached the maturation stage. No significant correlations were found between growth characteristics and wood properties. Significant variances in the height, stress-wave velocity, and basic density were found among the 10 families. The F-values and repeatability of the wood properties in the outer wood were higher than those in the inner wood. These results indicate that the properties of the outer wood are closely related to genetic factors. Thus, to obtain superior E. camaldulensis trees for solid wood production, the family selection should be conducted using the outer wood of aged trees.

Hasil tersebut searah dengan hasil Penelitian Prasetyo et al (2017) yang menyebutkan kerapatan kayu E. pellita adalah 460 (400 -550) kg m -3 pada umur 9 tahun di Sumatera utara. Rentang yang hampir sama ditemui pada Kerapatan kayu klon-klon Eucalyptus hibrid di Cina umur 5,5 tahun yaitu 468 -483 kg m -3 sesuai hasil penelitian Luo et al (2012) dan 404 -427 kg m -3 pada umur 51 bulan (Wu et al, 2015).…”

Industrial forest plantations have an important role in fulfilling the wood demand. Based on global industrial development, the forest plantations industry will increase in the following years. Eucalyptus pellita has become main species in Indonesia forest plantations because it has a short cycle and wood products are suitable to forest industry. The average productivity of E. pellita plantations in Indonesia is still low and high variation. In an effort to increase the productivity, the first step is a better understanding of genetic control on growth and basic density. This study aims to determine the genetic parameters for growth and basic density of E. pellita clones on two different sites of clonal trial. The trials are designed using RCBD. The number of clones tested in both trial was 30, 5 blocks and 25 tree/plot. The result of the study showed that the effects of clones vary greatly according the enviromental conditions. The clones-environemntal interaction of growth trait is higher than the basic density. This is in line with genetic parameters of growth trait that are less stable than the basic density. The expected genetic gain of growth trait is higher than the basic density and at the same time there was a weak genetic correlation (there is even a negative) between growth trait and basic density. Therefore carefulness is needed in selecting clones when the two traits are used as selection parameters.
