Judul: Control model of oil pollution in Rupat Strait of Riau
Abstrak: Rupat Strait is a small strait in the Strait of Malacca that lies between the coastal of Dumai City and Rupat island in Riau province. Rupat Strait has an important role in ecological because it has various types of mangrove for fish live and spawn, and also protect the coast from wind waves. Conversely, Rupat Strait also have an economic role as a strategic transportation routes that support the economy of Dumai. Oil industry in Dumai can processing raw oil into fuels with capacity of 170 000 barrels per day. Various economic activities were causing the Rupat Strait vulnerable to oil pollution. Oil pollution in sea waters was a complex problem that the solution must be done holistically using dynamical system analysis with software Stella 9:02. Oil response was observed at three sites that representing different levels of sensitivity in the waters of the Rupat Strait i.e. Lubuk Gaung Waters (very sensitive), Ketam Island Waters (sensitive) and Pelintung Waters (less sensitive). The calculation of pollution level based on the dissolved oxygen concentration and BOD5. Ketam Island, Lubuk Gaung and Pelintung included to light polluted criteria. Lubuk Gaung region showed a fairly dangerous response to oil pollution than other regions, because it was very sensitive to oil pollution. Instruments of technology (oilboom and dispersant) and regulation (legislation), either jointly (combination) or partially were needed to control the environmental impacts. Oil pollution control in the scenario III that using combination instruments (technology and regulation) was more effective than scenario I and scenario II usage of regulation and technology partially. The combination of technology and regulation can controlling the oil pollution in the area of Lubuk Gaung that secure to oil pollution. Secure status to oil pollution can increase the catch of fishermen in the Rupat Strait.

Judul: Pengelolaan Lingkungan Pesisir di Kawasan Pengembangan Industri Kota Batam, Provinsi Kepulauan Riau
Abstrak: The strategic geographical location of Batam has geared this region be developed by the government to be an industrial area which has an important value for the national economic aspect of life. This development of industrial area in fact has created an impact to other growing sectors in the region. However, from another side, the existence of the industrial development has resulted degradation to the coastal and marine resources, such as marine pollution and coastal ecosystem destruction (mangrove, coral reef and sea-grasses) including the decrease in fisheries productivity. The environmental degradation in the coastal and marine environment of Batam City was estimated to be more severe which have been triggered by certain agencies that commercially having only depending on short term benefits without taking care of environmental negative impacts. Therefore a proper management is needed taking into account all related aspects in order to minimize the negative impacts towards the minimum limits on the industrial development of Batam City in the coastal and marine environment. The purpose of this study is to know the quality of the coastal and marine environment, identification of issues and available problems, and to set up strategic coastal and marine environmental management based on impact analysis of industrial activities and its development on the water quality in the coastal environment of Batam City. Based on data analysis it could be put forward that in general the condition of the coastal waters of Batam City are not in a favourable situation. This is due to the worst values of the marine water quality and also the threats to the existence of coastal ecosystem and fishery resources. Some profound activities which impacted the condition are, among others, discharge of industrial waste, land clearing through destruction of forest areas and hills, coastal reclamation by way of mangrove area conversion for other purposes. Therefore proper policy guidance for management is needed taking into account all related aspects that will be supported through active participation of all existed components. The integrated coastal environmental management is needed to be implemented in order to avoid and minimize negative impacts from the industrial activities and its development on the coastal and marine environment. Consequently some strategies are needed in supporting the management. The protection and control for marine pollution by the industrial activity have to be implemented in an integrated and well planned manner which will be supported by the existing rules and regulations, governmental policy and management agencies including qualified human resources, are the prime priorities of the strategy that should be conducted.

Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
