One major river flowing through Bekasi City is Bekasi river. Total extent of the Bekasi watershed is about 39.045 ha, in 2002 with rainfall of 250 mm for 8 hours caused about 138 ha flooded in residents area for 2-3 days in Bekasi City, more extremely in 2005 with rainfall only 127 mm for 6 hours caused about 164 ha flooded in residents area for 3 days. This evidence showed that flood problem in Bekasi City is become worse, and seem to be more horrifying in the future. Therefore, the flood problem needs an extremely great attention. The objectives of the research is (1) analysis watershed condition; (2) analysis of the causes of flood over Bekasi City from the perpective of hydrology and hydraulic; (3) plan of Bekasi watershed management to reduce flood risk in Bekasi City. To obtain the purposes of this research, the method of analysis is devided into four main subjects: (1) analysis of watershed condition using SCS method; (2) hydrology analysis using hydrology modeling HEC-HMS; (3) river flow capacity using hydraulic modeling HEC-RAS and (4) plan of scenarios to reduce flood risk. There are four scenarios to overcome the flood problems: (1) similarly with government plan 2010;(2) managing Bekasi watershed area with conservation tillage; (3) build water retarded structure entire of watershed and;(4) combination of second and third scenarios. The research results shown that river flow capacity only 462 m³/s is not enough to flow the discharges, otherwise the land use is change and increasing the run off in upstream. Based on the problems, it is expected to overcome the flood problem by managing Bekasi watershed area with conservation tillage and build water retarded structure. It will reduce 28.58% of the discharge run off in 2020.

The objectives of this research were to identify gender relation, communication channels and the use of agricultural information, to analyze the correlation between gender relation and communication channels, the correlation between communication channels and the use of agricultural information. The research was conducted in the Sub-District of Pacet, District of Cianjur and Sub-District of Megamendung, District of Bogor in the West Java Province. The research used a method of survey taking 134 samples of organic vegetable farmers consisting of 67 men and 67 women. The quantitative data was obtained from the questionnaires given to the farmers and supported by qualitative data collected by in-depth interviews. The research results indicate that men often used personal communication, but women seldom choose the personal channel. Both men and women seldom used the mass media channel. Both men and women often use agricultural information for themselves for practice and comparison but seldom for discussion with others. Men and women were both active in information seeking and discussing the received information, but in the control of agricultural information men were more dominant than women. Among women, the group had a significant relationship with information control, whereas among men the mass media had a significant correlation with information control. The agricultural information from a personal channel was used by men for themselves for the purpose of practice, comparison, discussion, or diffusion. However, among women, the agricultural information was used for comparison, discussion, and diffusion. The group channel omong men was used to diffuse agricultural information whereas among woman it was for comparison, discussion and diffusion. The agricultural information from the mass media was used by men for their own knowledge, comparison and diffusion. Women liked to discuss agricultural information with husbands and families.

Tourism development should also pay attention to social components exist in the area, beside the physical and biological condition. Data were collected through literature review and in depth interview. There were 131 respondents consisted of government official (village head), community’s elders, non governmental organization, tourism entrepreneur, and community members which were not involved in tourism activities. Interaction between individuals of the community members in Gunung Sari Village showed more variations compare to Gunung Bunder 2 Village, due to background variation of community members. In general, both villages showed positive primary interaction between individuals and groups, since all individuals in a certain group share the same interest and objective. While interaction between groups were emphasized more on the short term economic interest of nature-based tourism activities rather than the long term nature based tourism development.

Sago palm (Metroxylon spp.) is a tropical plant adapted to marginal land such as fresh water swamp, peat swamp or brackish water. The objective of the researche is to identify physical and chemical habitat characteristics of sago palm in the Seram island, Maluku. The research was conducted in nine months from March to November 2009. The observation was conducted at three samples area, namely Luhu (West Seram District), Sawai (Central Maluku District), and Werinama (East Seram District). Soil and water samples were taken at samples area and analyzed at Soil Research Center Laboratory, Bogor. Result showed that sago palm at the Seram island can be found at four different habitat types, namely: 1) upland habitat/dry land, 2) temporary inundated fresh water swamp, 3) temporary inundated brackish water, and 4) permanent inundated fresh water swamp. Soil texture of these habitats characterized by clay-loam and silty-clay with average bulk density of about 1.20. The soil has acidic reaction that consists of medium soil organic and having medium cation exchange capacity (CEC). Except for Fe and Alwhich were high, the nutrient content of the soil was very low. Salinity of water was less than 1.0 ppt (part per thousand). Nitrate (NO₃^-), phosphate (PO₄^3-) and other cation such us NH₄⁺, K⁺, Ca²⁺, and Mg²⁺ were found relatively high in water. Micro climate condition under sago stands (clump of Sago) such us temperature, relative humidity, and sun radiation intensity are low with very narrow fluctuation. Micro-climate conditions were characterized by temperature ranging from 22,69^oC to 23,94^oC, meanwhile relative humidity ranging from 87,97 to 91,60%. In case of sun light intensity at near clump of sago palm reached of about 206,53 lux (12,40%).

The Sustainability of Corporate Social Responsibility (CSR) policy among the firms within Indomobil Group have difference performance from stakeholders view. PT Suzuki Indomobil Motor (PT SIM) have some sector that should be priority to be done like opportunity to work in PT SIM for local community and social disintegration between local community and PT SIM worker. For PT Nissan Motors Indonesia (PT NMI) and PT Hino Motor Manufacturing Indonesia (PT HMMI) the sector that should be priority are impact of company existence to increasing of prices of goods and services for local community consumption, planting tree activity, increasing amount of small economic and financial institution. The policy of CSR should be improvement CSR performance with keep increasing of business growth simultaneous. The management of CSR activity of Indomobil Group have important role to support company performance as good corporate citizenship in area where company operated especially in factory location.

A laboratory scale research to obtain environmentally safe effluent from Final Waste Disposal Site leachate in Galuga owned by Regional Government of Bogor City was conducted from July 2006 through to April 2007. The experiment of production tolerable threshold effluent was carried out by aerating the leachate in 4 different aeration rates (0, 10, 30 and 70 liters/minute). The research found that the most effective method to reduce pollutant was aerating at the rate of 70 liters/minutes. However, only some of pollutant (Cu, Zn, Pb and E.coli) can be reduced until below tolerable threshold.
