Penelitian dilaksanakan di wilayah Desa Peliatan, Kecamatan Ubud, Kabupaten Gianyar-Bali tahun 2005-2006.Penelitian dilakukan dengan menyelusuri jalur-jalur jalan yang ada di wilayah desa sambil mencatat jenis herba dan lianayang ditemukan. Tumbuhan ini ini kemudian dicek statusnya (dilindungi atau tidak), pemanfaatan, serta mitos yangberkembang dalam masyarakat tentang tumbuhan tersebut. Dari hasil studi ini telah berhasil diidentifkasi 100 jenis herbadan liana. Dilihat dari segi pemanfaatanya, bagian terbesar dari herba dan liana ini, yaitu mencapai 50% pemanfaatannyamerupakan kombinasi dari tanaman hias, bahan makanan, tanaman upakara serta campuran antara tanaman upakara danbahan makanan. Sebanyak 40% dimanfaatkan untuk penggunaan lainnya, serta 10% sisanya merupakan gulma, yangrelatif belum dimanfaatkan secara nyata oleh masyarakat. Dilihat dari segi mitosnya, 12% dari tumbuhan herba dan lianadi Desa Peliatan memiliki mitos. Sepuluh (10) jenis (atau 83% diantaranya) mempunyai mitos atau kepercayaan yangbernilai positif sedangkan yang negatif hanya 2 jenis (17 %). Dilihat dari segi perlindungan, maka dari jenis-jenis herbadan liana tersebut tidak ada yang termasuk jenis-jenis yang dilindungi peraturan perundang-undangan yang berlaku diIndonesia.

Abstract

A study on mollusks (Amphidromus peversus) has been carried out on Udayana University, BukitJimbaran (Bali, Indonesia) campus between November, 2003- November, 2005. The study was undertakenon a secondary forest on a limestone dry soil with dominant vegetation of Glerecydium sepium, Lantanacamara, Ceiba pentranda, and Acasia auriculiformis. Samples were randomly taken on quadrate samplings.Mollusks were captured on the land surface or on living vegetations. Results of the study showed that A.peversus has an average of shell length of 27.9 mm, shell width 18.0 mm , and body weight 7.90 g, number ofshell whorls 5.3, with the proportion of direction of whorl to the right of 55.3%. The shell of A. peversus hasno operculum. The color of the shell was yellow with brown stripes.The relationship between shell length (X) and with body weight (Y) can be represented by theequation of Y = 0.473 X – 5.32 (R2 = 11.9 %), which showed week relationships between those parameters.Meanwhile the relationships between the shell length (X1), width (X2) and body weight (Y) was best fitted bythe following equation : Y = 0.289 X1 + 0.0140 X2 – 3.47 (R2 = 94.9%).

Abstract

A study on birds (species and their characteristics) was carried out in Bedugul(Bali) between November and December 2004. Observation was made along transectlines which are set prior to the study. Species of birds observed were identified andrecorded. In addition, their distributions, status, source of food, reproductive seasons, aswell as migration patterns (whether migrant species or not) were determined. Thisstandard sampling strategy was also supported by casual observation and interview.Results of this study showed that Bedugul and surrounding area have a significantrole in conservation of Bali birds, because at least 56 species of birds have beenidentified in this area, which comprises of 18% of Bali birds. Conservation priorityshould be put on 8 species (14%) of the birds which are protected by law, as well as on 7% of endemic species (for Java and Bali). In addition, conservation effort should be alsogiven priority to 9% of birds that considered to be rare and potentially that be locallyextict. Habitat conservation should becoming focus of attention since it determines theavailability of food sources for those birds. Conservation on forest, plantation as well asshrubs should become focus of attention since these become habitats of more than a half(57%) of birds available in this area.

A study on birds has been conducted in Nusa Dua Tourist Resort area, Bali, betweenJanuary, 1999 and January, 2002. In this study, bird species was identified and theirpotentials for ecotourism-bird watching activities were analysed. From the field observationit was found that the site has a potential to be developed as a bird watching site. It can beseen from the diversity of bird species identified there, especially in the lagoon. In Nusa DuaTourist Resort area 83 bird species has been identified which is representing over 27% ofbird species on Bali. About 87% of those were classified as non-migrant species, while therest were migrant. Among those species, 6% were birds which were known to be restrictedtheir distribution to Indonesia. The strategic location of Nusa Dua Tourist Resort area alsoincreases its potential for development of bird watching activities. For development of theseactivities, holistic management approaches need to be implemented, the approaches of whichneed considering a balance between conservation, economic and empowerment of localcommunity objectives.

Abstract

Environmental Management System (EMS) is very important in pursuing sustainable development. Problems were then arising, how to implement SML in the dimension of the Tri Hita Karana, Balinese life philosophy, so it is fit with Balinese life. Thus planning, doing, checking, actuating and controlling should be applied in the dimension of spiritual, socioeconomy (community) and environmental aspects, three aspects on the Tri Hita Karana philosophy. Because tourism is a major source of income for the Balinese it is then interesting to see how the EMS which adopt the THK philosophy being implemented in Bali. Many things can be learnt from its implementation on tourism sectors, especially on hotel businesses.

There was no protected species found in this study. The macrozoobenthos had 2,28 level of index diversity. This indicated that the ecosystem at this area was in a stable condition with a medium level of macrozoobenthos diversity.
