Nyamplung (Calophyllum inophyllum L.) is one of the new alternatives of biofuels materials in the world. Hitherto, the information on the cultivation and processing techniques is very limited. This study aims to find out the growth of nyamplung on some cropping patterns on sandy beach Pangandaran in 4 (four) years. The experimental design used in this study was split plot design. The main plots were cropping pattern: agroforestry nyamplung, nyamplung monoculture and nyamplung + pandanus, and the subplot were fertilizer doses: (1) no fertilizer (control), (2) 5 kg of organic fertilizer + 100 gr/plant NPK and (3) 10 kg of organic fertilizer + 200 gr/plant of NPK fertilizer. Each combination treatment consists of 25 plants that were repeated 3 times , so that the total number of plants observed were 675 plants. The growth parameters observed: survival rate, height, diameters and number of branches of plant until 4 years. The results of this study showed that the interaction of treatments were statistically not significant. The growth of the plants was significantly affected by cropping pattern and fertilization. The Agroforestry pattern produces the highest survival rate and growth that is 97.33% with an average height of 220 cm and an average diameter of 5.08 cm. Recommended fertilizer doses are 5 kg of organic fertilizer for base and 100 grams of advanced fertilizer NPK twice a year.

Forest is a part of the ecosystem that provides environmental services. Deforestation may decrease forest function in an ecosystem. This study aims to build a spatial model of deforestation in a forest management unit (FMU) of Poigar. Deforestation analysis carried out by analyze the change of forest cover into non-forest cover with post classification comparison technique. Driving forces of deforestation carried out by spatial modeling using binary logistic regression models (LRM). Result of logistic regression model was used to predict the deforestation in 2013 and compare the prediction result with actual deforestation. The result showed that forest loss from the 2000 to 2013 period amounted 12,668.2 hectares. Deforestation in FMU of Poigar influenced by six factors there are distance from the road, distance from the settlement, distance from the river, population density, elevation and slope. Logistic regression model was built using five explanatory variables that are the distance from the road, distance from the river, population density, elevation and slope. Population density and accessibility is the most influented factor caused deforestation in FMU of Poigar. Prediction of deforestation could predict about 58 % of actual deforestation spatialy, so spatial models of deforestation could be an information to guidance on future management of FMU of Poigar.

This study aims to determine the level of farmers participation in the implementation of land rehabilitation and soil conservation (LRSC) techniques where appropriate to the micro watershed through PRA and PAR approaches. The techniques of LRSC both mechanical and vegetative methods have been built in a participatory manner in the demonstration plots of 2 ha in Datara micro watershed and of 2.5 ha in Mararin also micro watershed, South Sulawesi. Gully plug equipped with stick-scale and V-notch weir were constructed in Datara micro watershed and concrete tank of mud and runoff was built in Mararin micro watershed to monitor the impact of LRSC actvities to sedimentation and runoff level. The results showed the level of farmers participation at both locations fluctuated in the category of low (<50%), moderate (50-79%) and high (>80%) against targets LRSC activities that have been agreed at a meeting of the group. The level of participation is determined from the condition of the microhydro electric power who have built together. Participation of farmers on the application of LRSC on both plots are: willing to lend of their land for the location of demonstration plots, planting and maintaining trees for timber production, building and maintaining contour terraces and channel of water drainages, maintaining grass and gliricidia as reinforcement terraces for soil conservation techniques. Activities of LRSC impact plots show that layers of sedimentation and runoff volume decreased in the research sites. Demonstration plots in Datara, high sedimentation layer in the second year (2011) in gully plug average of 32.72 cm decline to 7.14 cm in the fourth year (2013), as well as runoff discharge 44.47 liter/sec in 2010 down to 22.8 liter/sec in November 2013. in Mararin plots the average height of a layer of mud in the tank in 2011 from 4.89 cm decline to 1.99 cm in November 2013 and the runoff volume 8.5 liter/sec down to 5.6 liter/sec at the same time.

Land use in a watershed should consider land capability and watershed carrying capacity so that the land can optimally. Agroforestry is a land use system that not only aims to generate income for the people but also to maintain hydrological conditions of a watershed. This research aims to evaluate the hydrological responses due to the application of agroforestry system on several land use pattern that has been changed. There are three steps in the analysis: (1) Assessment on land use planning (RTRW), (2) Land use suitability classification for agroforestry system, and (3) Development of scenarios for suitable land use of agroforestry system for hydrological function. The results of this study show that the application of agroforestry system of woody plant (i.e. sengon), fruit plant (i.e. Nephelium lappaceum), annual crops (i.e. clove, coconut, Parkia speciosa and banana), perennial crops (i.e. cardamom, and banana), and seasonal crops (i.e. cassava) on unsuitable land use gives the lowers on Coefficient of River Regime (KRS), specific discharge, Run off Coefficient (C) and Total Dissolve Sediment (TDS). This agroforestry system can be applied on several land use pattern that has been changed, because this system not only aims to generate income for the people but also to the maintain hydrological condition of a watershed

Mangrove forest at Tanakeke Island has important roles both for ecology and economy. High pressure on mangrove caused mangrove degradation in the island. Knowledge of ecological conditions and health of mangrove forest are essential for mangrove ecosystem management at the island. The study aims to determine ecological characteristics and health status of mangrove forest at Tanakeke Island, Takalar District, South Sulawesi. This study employed quantitative methods using field survey with observations using plots of 10 m x 10 m. Observation plots were located evenly all over the island. Results showed mangrove forests at Tanakeke Island consist of 11 species belong to 8 families. Shannon-Wiener diversity index reached 2.01, 1.88, and 1.18 for tree, sapling, and seedling, respectively. Importance Value Index reached 115.31, 172.11, and 108.89 for tree, sapling, and seedling, respectively, and dominated by Rhizophora stylosa at all growth levels. Structure of mangrove forest stands resembles the letter "J" inverted, which means the structure of forest stands were quite normal as a result of the good process of plant regeneration. The density reached 706 ind/ha, 4,824 ind/ha, and 23,382 ind/ha for tree, sapling, and seedling, respectively. In general, mangrove forest health levels at Tanakeke Island were categorized in low to moderate levels.

Mahogany woods from community forests generally have relatively low qualities due to lack of maintenance activities and for their young harvesting stage. Heat treatment is known as wood modification method that could improve the quality of the wood. The aim of this study was to determine the interaction effect of temperature and method of heat treatment on the chemical properties of young mahogany wood. Materials used in this research were mahogany wood boards from community forest which were heat-treated using oven and steam methods performed at the temperature of 90°C, 120°C, and 150oC for 2 hours. In this research, some chemical changes were analyzed. Results of the research showed that the interaction of temperature and heat treatment method gave a significant decreasing on the pentosan amount, and hot-water extractive solubility, particularly the steaming at 150oC. The increasing temperature of heat treatment significantly decreased the content of holocellulose, α-cellulose, hemicellulose, and pH values whereas it increased lignin content, extractives (cold-water and alcohol-benzene extractives) and solubility in 1% NaOH. Steaming method provided lower levels in the content of holocellulose, ethanol-benzene extract, cold-water solubility, and pH values compared to the oven heating. However, the steaming method over 1200C should be considered as it would reduce the wood strengths.

The seed of trema (Trema orientalis Linn. Blume) is categorized as physiologically intermediate which decline faster during storage compared to orthodox seeds, resulting in the changes of its viability, vigor and biochemical contents.The study was objected to determine the changes of viability, vigor and biochemical contents of trema seeds during storage. The seeds were collected from Badung - Bali province. Seeds testing were carried out in a laboratory and glasshouse of Forest Tree Seed Technology Research & Development Centre. Biochemical analysis was implemented in Soil and Plant Laboratory, Seameo[1]Biotrop. A Completely Randomized Design was employed in this trial with a treatment of storage periods (0.1, 2, 3, 4, 5 and 6 months). The parameters were germination capacity, germination speed, moisture content and biochemical content including carbohydrate, protein and fat. The results revealed that all the parameters were significantly affected by storage periods. After six months periods of trema seeds storage, it would caused the decrease of moisture content (6.2%), germination capacity (61%), germination speed (2.5%/etmal), carbohydrate (19.2%) and protein contents (1.8%). However, the content of fat was increased significantly (10.2%).

The demand of teak (Tectona grandis L.f.) wood for the national industry can only be fulfilled about 0.75 million m3/year from 2.5 million m3/year which is caused by the long of harvesting time and the derivation of suitable land for teak due to climate change. Indonesia has a wide area of dry land to develop teak plant, so that, fast growing and drought resistant teak seedling is needed. The aim of this research was to compare the resistance of tetraploid and diploid teak clone to drought stress. The research was conducted in the greenhouse using Randomized Block Design with two factors and 9 replications. The first factor was clone i.e. diploid (2x) and tetraploid (4x). The second factor was drought stress levels consisted of 5 watering intervals i.e. 3 days, 7 days, 14 days, 21 days, and watering only at the treatment began. Plant height, stem diameter, number of leaves, leaf area, leaf thickness, leaf water potential, stomata, root system, and plant dry weight were observed to evaluate the plant growth. The result showed that the growth of both tetraploid and its diploid seedling clones were declined under drought stress. However, the growth of tetraploid seedling is better than its diploid seedling.
