One of main supplier on wood industry is Antocephalus cadamba from private forestland. A. cadamba can be harvested at 6 years with the price of Rp 900,000.00 per cubic meter. A. cadamba has been planted in various areas, one of them in Widodomartani, Ngemplak, Sleman, Yogyakarta Province. The succes silviculture A. cadamba if from planting to harvesting with good practice. One of supported succes planting is used multicropping. This research aims to determine the growth at one rotation (six years) with initial planting used multicropping.Planting is done with a distance of 2x2 m in the planting. The growth data (height and diameter) was taken in each treatment (6 treatments) and each treatment tree repeated. The data obtained were analyzed by anova and if there were significant differences in the factors, followed by the LSD test. The analysis showed that the treatment is significantly effect agants height and diameter growth. The growth rate of A. cadamba at 6 years planted is 14,48 m height and 14,61 cm diameter. Key words: Growth, Jabon (Antocephalus cadamba), Initial multicropping

The market needs will be fragrant citronella oil increases, but it is not worth the production and quality of fragrant Lemongrass oil is produced. The purpose of this study, that is, to figure out the best combination of sources of raw materials and factors of the size of the craftmanship the leaves against the yield and quality of fragrant citronella oil. Research design used was Random Complete Factorial Design, using two combination treatment that is the source of the raw material and the size of the craftmanship leaves. The observed parameters include: color, yield, citronellal, citronellol and geraniol. The results of this study indicate that the color of the resulting eligible SNI 06-3953-1995 that is pale yellow to yellow-brown. Combination treatment of the source of the raw material and the size of the leaf is very different from real craftmanship against yield oil of citronella scented with the highest average on the source of raw material for the village of Wedomartani, craftmanship and size of 0.93% leaves 10 cm that is 0.94%. Chemical content of citronellal shows that the source of the raw material and the size of the different leaf craftmanship not real. Chemical content of citronellol and of the raw materials sources that geraniol very different real, whereas the size of different leaf craftmanship not real. The average content of chemical sitronellol and geraniol at the source of the raw materials of the highest village of Kebonharjo, the content of citronellol 13.11% and geraniol content 34.84%.

Woods which have low natural durability are easy to be attacked with wood staining fungi (blue stain) so can decrease its wood quality. Syzygium aromaticum, Melia azedarach and Piper betle contain of active components (botanical fungicide) that can be used as natural preservative to prevent staining fungi attack. The purpose of this research is to know effect of botanical fungicide species and preserved wood investigated, i.e Paraserianthes falcataria and Toona sureni on the attack intensity of wood staining fungi. Results of the research showed that interaction between botanical fungicide and wood species gived very significant effect on the attack intensity of wood staining fungi. The lowest of attack intensity was resulted on Toona sureni that had preserved by Melia azedarach leaf extract. The leaf extract of Syzygium aromaticum, Melia azedarach and Piper betle could keep Paraserianthes falcataria and Toona sureni wood against staining fungi. Toona sureni wood was more resist against wood staining fungi than Paraserianthes falcataria, it was due to higher extractive in Toona sureni than Paraserianthes falcataria. To preserve woods which had bright colour such as Paraserianthes falcataria, more suitable to use Melia azedarach leaf extract which not change wood colour.

Agroforestry, the practice of growing trees and crops in interacting combinations, has a pivotal role to reduce the CO2 concentration in the atmosphere, and it subsequently sequesters the carbon in part of stems, branches, roots, and crowns of the trees composing their vegetation communities. The objective of the research is to know the carbon sequestration in the three agroforestry practices; those are multilayer tree garden, taungya, and home garden. The research was carried out from April 2017 to March 2018 at Sragen and Karanganyar regency central Java Province. Plot method, with the plot size of 20m x20m for trees, 10m x10 m for pole, and 5m x5m for sapling, was used in the sampling. The carbon sequestration was measured by Chave's allometric equation. The carbon sequestration of above ground the trees planted at taungya was 265.18 kg C ha-1 y-1, in home garden was 236.29 kg C ha-1 y-1, and in multi layer tree garden was 290.14 kg C ha-1 y-1. Seasonal fluctuation of the higest carbon sequestration in home garden occurs on October-December; in multilayer tree garden occurs on January-March; and in taungya occurs on July-September.

Seventy trees have choosen by diameter distribution, healthy and straigh stem. Every sample trees were measured with stem analysis method. Rotation of maximum volume production define by growth curve, mean annual increament (MAI) and current annual increament (CAI) curve. The result show that height youth stage begin 2 until 6 year, diameter youth stage begin 3 until 10 year, volume youth stage begin 4 until 25 year and rotation of maximum volume production is 25 year.
