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.

Judul: Query Expansion based on Bilingual Dictionary Using Conditional Probability
Abstrak: Query expansion is a technique that can be used to bridge vocabulary gaps between queries and documents in the collection. With query expansion, user will be helped to formulate queries well so that user will optimize the search result. In this study, the expansion term was resulted from the translation of bilingual dictionary. Subsequently, several terms of expansion were elected based on the closeness of its relationship with the original query. This research showed that conditional probability can be used to select expansion term in bilingual translation method query expansion. The result of 1000 documents was more than 97% relevan document can be retrieved by this system. The more expansion term used, the larger number relevan document was retrieved.
