Fruit is one commodity that can provide benefits in the economic chain. Various types of fruit crops commercially valuable but untapped potential. Among them are red durian, mangosteen and srikaya Ganal Ganal. In the market, the three types of fruit is very desirable consumer, but its existence is very volatile. For that, since 2004 Balittra began to take steps to conserve a variety of exotic fruits typical marsh exploration results in some swamp areas in South Kalimantan, Central, and East. Conservation efforts are part eksitu conserving plant germplasm exotic fruits swamp land.
Eksitu conservation activities are a continuation of the activities of exploration activities have been conducted in previous years. Plant material that has been collected from various regions of the marsh area, need to be protected. The activities include data collection and grouping of plants by type, then planting in the field in accordance with its type. Includes plant maintenance: fertilizing, weeding and pest and disease control. Plant growth observations performed to determine plant growth keragaan include: measurement of plant height, stem circumference and width of plant canopy.
Until the end of 2006, the number of plants that have been in the conservation of Banjarbaru KP 129 plants there, which consists of 8 groups of plants. While the KP Belandean there are 96 plants consisting of 6 groups of plants. Among the fruit crops are successfully conserved rambutan and durian. The results of observations and observations of plants in the field showed that not all plants can adapt well in the conservation area. This is because of differences in habitats of the plants that were collected. To find out keragaan adaptation of various plant collection was conducted measurements of plant height, stem circumference and canopy width. Plants grow at a higher, more adaptive categorized in the conservation area.
BASIN MANAGEMENT FOR sustainability And biodiversity FISH By: Iis Jubaedah Lecturer Department of Fisheries Guidance STP Jakarta There are two major problems that occur in fisheries activities. Eutropfikasi First, the enrichment process that resulted in the biomass of plants and animals increases and the sedimentation rate increased, consequently the shorter the life aquatic. Second, the decline in fish populations caused by environmental degradation, increasing population, and the more intensive fishing. Second problem, if not addressed with conservation activities will be severely threatened. Fishery activity is an important additional activity in periran reservoirs. These activities should be realistic and thorough with attention to ecological rules. In the placement of fish, should know the types of fish and associated habitat types as well. The presence of fish in reservoirs are influenced by several abiotic factors, such as: Morfohidrodinamik (between reservoirs flow zone, transition, and pooled), light, temperature, flow, degree of acidity (pH), and oxygen. In addition, there is also the influence of biotic factors such as: natural food, predation, competition, and human factors. Management of fishery resources and attention to ecological aspects of biology. Thus, placement take into account spatial, temporal, time, type of fish, fish eating habits, and patterns of reproduction. Knowledge about the distribution of these fish will provide information on sampling methods and determine methods of capture, and management that led to the conservation of fish populations. Then, can be cultivation or the preservation of fish production. The process of this activity consists of manufacturing management system according to the physical form of zoning, habitat preferences and abundance of fish, ease of achievement, as well as replanting continuously. Many factors can threaten the sustainability of aquatic ecosystem, and therefore the management of interdisciplinary expertise required. Development should be based on conservation and protect the structure, function, and diversity of natural ecosystems. Biodiversity conservation is only possible if sustainability is inherent in human life

BAY AMBON and its management
Research Oseanologi Jakarta
Ambon Bay is one of the most beautiful bay in the province of Maluku. However, along with the modernization, the need for more natural resources are not controlled. This impact on the growing number of waste and ultimately destroy the ecosystem. This article discusses the various types of damage to ecosystems, the factors that cause damage, and management efforts.
Damage to the aquatic ecosystem has reached the bay ambon worrying category.
This situation threatens the sustainability of natural resources and environmental functions of marine and coastal environment from destruction. These defects include: first, the physical environment and damage ecosystems. Second, damage to mineral and water resources, the third reduction of biological resources, and the final form of pollution (such as waste oil, heavy metals, pesticides, solid waste, and waste hot water).
Responding to this, established various laws and regulations which form the basis for environmental management. In particular Law No 4 of 1982 and the main provisions of Environmental Impact Assessment No. 29 of 1986 (now the PP No. 51 of 1993), and the decision of the Minister of Environment Quality Guidelines for Environmental Standard Setting. But institutionally, the written rules can not be applied properly.
Because the application of the rules is not good, so that Ambon Bay aquatic ecosystem remain stable, sustainable, and useful for future generations, it is necessary to take the actions of Ambon Bay ecosystem management. In this paper, the management measures include: the prohibition, prevention, control and guidance, counseling, conservation, development, research, and application.
