Memudarnya nilai kearifan lokal masyarakat dalam pengelolaan sumber daya air

Abstract: Water is vital for human and thus it has to be made available for our life Many communities in Indonesia , with their local knowledge, customs, and culture that are passed from generations, utilize water resources in their areas to meet daily needs They manage the resources and live in harmony with the surrounding nature The wisdom of community on water resource management, unfortunately, has experienced a shift Water has then become an important issue that requires significant attention This paper discusses shift in the value of local wisdom on water resources Data and information in this paper is based on desk reviews from research/assessment results, books, documents and the author’s field experiences in implementing relevant researches The discussion focuses on the waning of local knowledge and wisdom as social capital in the provision of community water supply and as a form of their protection against water resources, such as the erosion of togetherness and mutual cooperation among members of the community, change in the value of water from social good to commercialization, the waning of local and traditional institutions, and the community’s sense of belonging to their common property resources This paper also analyze the shift of local wisdom’s role in maintaining balance and harmony between the communities and their surrounding environment, and challenges to the existence of local wisdom associated with population pressures, modernization and development activities with less attention to the preservation of water resources and environment

REVIEW: Symbiosis between the Giant Clams (Bivalvia: Cardiidae) and Zooxanthellae (Dinophyceae)

Abstract: Giant clams are the largest bivalves in the world that maintain a mutual relationship with zooxanthellae. Individual giant clam can harbor heterogeneous zooxanthellae, at least four taxa in genus Symbiodinium. The Symbiodinium lives in the zooxanthellal tubular system, a tube structure arising from one of the diverticular duct of the clam’s stomach. Since the numbers of zooxanthellae is the one of some significant factors contributing to the clams growth and survival, the giant clams need to adjust the number of zooxanthellae for physiological reason with unclear mechanism. The important role of the symbiotic relationship to the clams can be seen on the survival, growth and nutrition of the clams. There are at least two significant factors determining the symbiosis, i.e. water temperature in related with level of light intensities and ammonium-phosphate rate. Some topic is still unclear, i.e. the determination of species in genus Symbiodinium, the mechanism for adjusting the population numbers of the algae and what kind of environmental factors determining the symbiosis. Thereby further research is still needed to clarify those missing.© 2008 Jurusan Biologi FMIPA UNS SurakartaKey words: giant clams, zooxanthellae, Symbiodinium, symbiosis

Combination Base64 Algorithm and EOF Technique for Steganography

Abstract: The steganography process combines mathematics and computer science. Steganography consists of a set of methods and techniques to embed the data into another media so that the contents are unreadable to anyone who does not have the authority to read these data. The main objective of the use of base64 method is to convert any file in order to achieve privacy. This paper discusses a steganography and encoding method using base64, which is a set of encoding schemes that convert the same binary data to the form of a series of ASCII code. Also, the EoF technique is used to embed encoding text performed by Base64. As an example, for the mechanisms a file is used to represent the texts, and by using the two methods together will increase the security level for protecting the data, this research aims to secure many types of files in a particular media with a good security and not to damage the stored files and coverage media that used.
