Abstract

The Balinese is comprised of genealogical patrilineal clans named as soroh. However, remnants of ancient Bali Mula communities have their own local genealogy which differ from the general soroh. The Pasek Trunyan together with Pasek Kayu Selem, Pasek Celagi, and Pasek Kayuan are part of Bali Mula which believed to be descendants of one ancestor, Empu Kamareka. Here we reported genetic variation of the Terunyan society. The microsatellites Y-chromosome markers (DYS19, DYS390, DYS393, and DYS395) were used in this study. There were 12 alleles found and the result showed the low genetic diversity (D = 0.28 + 0.05) within Terunyan society. Nine haplotypes based on allelic combination were found, dominated by major haplotype with frequency of 0.50 which spread out in many genealogical lineage called dadia. The haplotype data showed that Terunyan society derived from many gene sources. Key words: patrilineal, pasek, soroh, dadia, haplotipe

Abstract

Efforts to improve food security in Indonesia, particularly Bali, need to be supported by improvements in cultivation techniques, including the management of pests and diseases. Meanwhile, legume crops are often attacked by stem rot diseases which potentially decrease production and leads to economic losses. This disease is generally caused by the soil-borne pathogenic fungus Sclerotium rolfsii or Athelia rolfsii. The macroscopic and microscopic morphologies of these two species are the same and difficult to distinguish, hence, molecular identification is needed to differentiate between the species. Therefore, this study aims to isolate and molecularly identify the fungi causing stem rot disease in local legume plants in Bali. The methods used include isolation of pathogenic fungi from legumes showing symptoms of stem rot disease, pathogenicity test, identification of isolates with the highest virulent levels, DNA extraction, DNA amplification by PCR and electrophoresis, ITS region sequencing and computer analysis sequences. The isolation procedure identified six fungal isolates coded SKT, SKB1, SKB2 SKB3, SKL and SKN isolates. SKT isolates had the highest virulence rate as indicated by the pathogenicity test of peanut plants. Furthermore, molecular identification results show that SKT isolate is Athelia rolfsii, a similar clade with the fungi sequences in GenBank with 100% bootstrap support.

Abstract

A study on plants species as resource of food for Bali Starling (Leucopsar rothschildi Stresemann, 1912) was carried out in Ped Village, Nusa Penida, Klungkung Bali, Indonesia between March-April and between August-September, 2006. Explorations methods were conducted in making inventory of plants species and part of plants as food resource. Direct observations were conducted to observe feeding activity of the starling after release. Results of this study showed that 105 plants species have been identified in Ped village. About 30 species (in varied habitus of trees, shrubs, and herbs) acted as food resources for the starling. Part of plants species which had been used as food resources were fruits and seeds. Besides plants as food sources, insects were also available on the studi site (such as grasshopper, ants, caterpillars, butterflies). In addition there were also small reptiles as source of food for the the bird. Plants availability as source of food supports ex-situ conservations of Bali Starling in Ped village.

Abstract

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

A study on plants species sighted around mangrove information centre ofNgurah Rai Mangrove Forest (Tahura Ngurah Rai), Sothern of Bali province(Indonesia), was undertaken in March 2004. The plants sighted on both sides of themangrove trail were listed. Their potential as ecotour attractions was then identified.Results of the study showed that there were 42 plant species identified aroundmangrove trail of this forest. Twelve mangrove species in this ecosystem may act asmajor attractions to the tourists doing tracking there. Information on protected species,the potential use of plants for humans, such as for animal fodder, medicine, the use inancient Balinese community, in traditional way of life of Balinese which is last untilnow, the use for offering in Hindu’s ceremony may also be interesting for tourists.Some plant species may cause problems to tourists who doing trekking so needprecaution, including on those which cause bleeding and disturbance to humanbreathing.

Abstract

Research on conservation and the use of plants as sources of traditional medicine wascarried out in Trunyan village. Objectives of this research are as follows: (1) To find outplant species used as traditional medicine; (2) Which parts of plants utilized for medicine; (3)Names of diseases which can be treated, and (4) What action has been taken by the villagersto conserve these plants. The research was carried out for two months within five banjar:Banjar Mukus, Puseh, Madia, Bunut, and Banjar Trunyan. Data were collected throughinterview, on site observation and literature review, and then they were qualitatively as wellas quantitatively analyzed and presented in tables.Results of this research showed that 90 species of plants were identified as materialfor traditional medicine in Trunyan village. Leaves were parts of plants which were usedmost (46.21%), and diseases which can be cured such as coughing, skin diseases, stomachdisorder, rheumatics, hard breathing, fever, and headache, the diseases of which aregenerally not fatal. From the conservation perspective, it was found that very littleproportion (10%) of this species which have been cultivated.

Abstract

Cocoa fruit peel (Theobroma cacao L.) is an agricultural waste with potential as an antibacterial agent due to its bioactive compounds. Pathogenic bacterial infections, such as Staphylococcus aureus and Escherichia coli, pose significant health problems, particularly due to the increasing resistance of bacteria to antibiotics. This creates a demand for alternative, safer, and more effective antibiotics. This study aims to evaluate the effectiveness of cocoa fruit peel extract in inhibiting the growth of S. aureus and E. coli, determine the Minimum Inhibitory Concentration (MIC), and identify the bioactive compound groups contained in the extract. The methods used in this study include maceration for the extraction of cocoa fruit peel, the well diffusion method to test the antibacterial activity of the crude extract, and phytochemical testing to identify the bioactive compounds in the extract. The results show that the crude extract of cocoa fruit peel can inhibit the growth of S. aureus with an inhibition zone diameter of 26.75 mm and E. coli with an inhibition zone diameter of 25.75 mm. The MIC test revealed that S. aureus was more sensitive to the extract, with an MIC at a concentration of 0.7%, resulting in an inhibition zone diameter of 5.35 mm, while E. coli showed an MIC at a concentration of 0.8%, with an inhibition zone diameter of 5.36 mm. The most effective concentration was 50%, with inhibition zone diameters of 20.56 mm against S. aureus and 21.06 mm against E. coli. Phytochemical testing showed that the cocoa fruit peel extract contains alkaloid, tannin, saponin, triterpenoid, and flavonoid compounds. Based on the results, cocoa fruit peel extract demonstrates potential as an effective natural antibacterial agent against S. aureus and E. coli.
