Membangun pariwisata bersama rakyat: kajian partisipasi lokal dalam membangun desa wisata di dieng plateau

Abstract: Development as a process of life change should involve communities as intergral elements. People should not only be regarded as objects of development. The paradigm of the bottom up planning expects people to act as both the subject and object of development. In the context of the development of rural tourism, the planning process should involve the local communities from the beginning. Dieng Plateau as a tourist site has a diversity of attractions, and tourist-oriented villages are designed by local communities to complement the tourist attractions in Dieng. This Study focuses on the participation of the communities in western Dieng in developing tourist villages in their area.Various stages of the planning are completed collectively and then put into action together. By applying action research methods, this study has the following results: (1) the identi cation of problems in the development of rural tourism, (2) the mapping of the potential of rural tourism, and (3) the identi cation of potential inter-agency networking to support sustainable rural tourism in western Dieng.

Bacteria, parasitic agents and rotaviruses associated with acute diarrhoea in hospital in-patient Indonesian children.

Abstract: Faeces from children (aged from one month to 12 years) with acute diarrhoea admitted to hospital in Yogyakarta, Indonesia, from June 1978 to June 1979, were examined for the presence of enteric pathogens. One or more recognized enteropathogens were identified in 56% of children. Rotaviruses were identified in 38% of all children. Toxigenic coliforms (predominantly Escherichia coli) were isolated from 12% of children. Salmonella sp. (6%), Shigella sp. (4%) and enteropathogenic parasites (predominantly Trichuris trichiura) from 3.5% of children. Mixed infections with two or more enteric pathogens were found in 7.6% of children. The incidence rate of each pathogen was correlated with age of the child, socio-economic level of the family and duration of breast feeding. Toxigenic coliforms were equally common in all age groups from both well-to-do and poor families. Enteropathogenic parasites appeared in increasing frequency with age. They were more common in artificially fed children and in children from families of low socio-economic level. The occurrence of multiple infection with mixtures of enteric pathogens increased with increasing age. Mixtures of parasites and other enteric pathogens only occurred in children with acute diarrhoea. These results provide baseline data about the relative importance of different enteropathogens in Indonesian children.

Habitat Use and Trophic Niche Overlap of Two Sympatric Colobines, Presbytis potenziani and Simias concolor, on Siberut Island, Indonesia

Abstract: According to ecological theory, the concept of niche differentiation is essential to our understanding of how sympatric species can limit competition over resources. We here examine ecological niche differentiation in 2 sympatric Asian langurs, Presbytis potenziani and Simias concolor, both endemic to the Mentawai Islands off the west coast of Sumatra. We collected data (home range size, canopy use, activity budgets, diet, and niche breadth and overlap) using GPS and scan/focal animal sampling methods on 2 groups of Presbytis potenziani and 3 groups of Simias concolor living in a mixed primary rain forest in northern Siberut. Results show that home ranges of the 2 species overlapped completely and that the home range size of Presbytis potenziani was ca. 4 times larger than that of Simias concolor. Lower canopy levels ( 20 m. Apart from foraging and other activities, there was little difference in overall activity budgets of the 2 species. Regarding diet, although 60% of all food species examined were used by both langur species, they shared only 3 of the 10 most commonly eaten species. Presbytis potenziani fed more selectively on fruits, whereas Simias concolor fed predominantly on leaves. Levin’s niche breadth indices revealed that the diet of Simias concolor is more general (0.34) than that of Presbytis potenziani (0.22). Based on a Pianka index of 0.32, we conclude that there is a relatively small food niche overlap between the 2 colobine species and that diet represents an important mechanism enabling their coexistence.
