Subterranean termites are a group of termite that causes economical loss in the timber and crop cultivation business. In Indonesia, subterranean termites are found attacking garden plants and forest plants such as coconut tree, cocoa tree, palm oil tree, and pine tree. Besides, subterranean termites also damage a lot of construction buildings which are made from wood. In Indonesia, it is difficult to effectively prevent the growth of subterranean termite. One of methods to improve wood durability towards subterranean termite threat is to preserve the wood. Sengon tree bark extract, soursop leaf and tobacco leaf are considered to be used as natural preservatives. This research is aimed to find out the effect of extractives of sengon wood, soursop leaf, and tobacco leaf on the mortality of subterranean termite, and this research is aimed to find out which extract substance that has the most retention, mostly affects subterranean termite mortality, and has the least weight loss. This research used an experimental method carried out in the laboratory, using a complete randomized design design, with four treatments that were repeated five times.\ The results showed that the extractives of sengon bark, soursop leaves and tobacco leaves had an effect on reducing the mortality rate of soil termites but were not significantly different in the retention rate. However, tobacco leaf extractive substance has the most effect in reducing the intensity of subterranean termite invasion and causing the least damage.

The existence of Tahura Inten Dewata have other functions as a Green Open Space in the process of reducing pollutants and climate stabilization. Vegetation has the ability to store carbon stocks, but the potential of Tahura Inten Dewata in storing carbon has not been studied. Object of research is carbon stock estimated in Tahura Inten Dewata. The method of research by storing it in wood density and biomass of tree which has a total area of ± 35.81 Ha. The results of these calculations will obtain the value of biomass, and carbon stocks represent 47% of the value of biomass. he total carbon stock in Tahura Inten Dewata is around 15,995.89 kg or 15,995 tons.

The condition of social, economic, and culture of forest community has effect to forest condition. Desa Sindulang is one of village that community forest in Taman Buru Masigit Karembi that has majority of farmer and low economic condition. But commodity planting is carried out without an evaluation of the land to determine the level of suitability of the land with the commodities planted. The method by overlay Land Mapping Unit with society land use then analyze of matching suitability land. The results of evaluation divided in 3 units, are : 1) unit I which have land suitability class values with forestry commodities such as Suren (Toona sureni) and Coffee (Coffea Arabica) while agricultural commodities such as Broccoli (Brassica oleracea), Chili (Capsicum annum), Banana (Musa acuminate) and Cabbage (Brasica oleracea). 2) Units II which have land suitability class values with forestry commodities such as Suren (Toona sureni) and Coffee (Coffea arabica) while agricultural commodities such as Tomato (Solanum lycopersicum). 3) Units III which have land suitability class values with forestry commodities such as Suren (Toona sureni), Africa (Maesopsis eminii) and Coffee (Coffea arabica) while agricultural commodities such as Tomato (Solanum lycopersicum), Eggplant (Solanum melongena) Broccoli (Brassica oleracea), Chili (Capsicum annum), Cabbage (Brasica oleracea) and Pineapple (Ananas Comosus).Keywords : Agroforestry, Land suitability, Sindulang Village

Cattle food greenery is an important factor in supporting ruminant farming to improve optimally with good result besides breeding factor and procedures. Ruminant farming needs greenery feeding at least 10% of its weight to fill up its energy needs. A good quality feeding must be provided continually to support the ruminant farming. People in villages use farming areas, plantations, and vacant areas along the streets as plant production area for their livestock, and people living near the forests use forest area as greenery source for their cattle. However, people recently have little awareness to preserve the forest due to their lack of knowledge to value the advantages of the forest they benefit from every day. This circumstances frequently lead to pressure towards the forest. This research is aimed to find out the amount of cattle food greenery in every family unit monthly, to know the economy value of cattle food greenery which is earned by the people from the forest area, and to inform people to raise ther knowledge and awareness towards the importance of forest use and its preservation. This research used survey method to obtain data in current condition by involving 140 respondents. The result shows that there are 8.650 sacks (50 kg each) of cattle food greenery which are earned by each family unit from the forest, with 62 sacks approximately. The total economy value of cattle food greenery is Rp. 126.600.000 monthly with the average number as much as Rp. 904.285,71 per family unit.

Gandaria (Bouea macrophylla Griff) is the identity flora of West Java Province. Naturally, the gandaria habitat in West Java is found only in the Yan Lapa Nature Reserve (CAYL) and Dungus Iwul Nature Reserve (CADI). In the ecosystem of CADI, and CAYL the position of gandaria in the community shows a low level of dominance. The presence of invasive species in CAYL and CADI is feared will threaten the stability of ecosystems in the region in the future including the presence of native flora. This study aims to study the level of tolerance and adaptation of gandaria in nature by knowing the pattern of individual spread in the gandaria population and the type of gandaria association with other species in various environmental. This is interesting to study because of the limited efforts of species conservation and genetic conservation of gandaria, while the condition of the natural population is increasingly threatened. Individual distribution patterns in gandaria populations in CADI and CAYL are random and clustered. Gandaria at Dungus Iwul Nature Reserve and Yan Lapa Nature Reserve are positively associated with iwul, whereas the Hawuan is negatively associated. Gandaria is not associated with asam keranji, manii, kokopian, leungsir, putat, and teureup. However, gandaria is not with menteng monyet dan kitulang in CADI while in CAYL have positive position.
