Abstract

This research was conducted in Serangan island in August, 2004. Ten plots assampling units were taken using Systematic Plot Design. Two parameters : ImportanceValue and Diversity Indices were determined on vegetation analyses. Samples were takenfrom three different locations. Soil analysis was conducted for determining macro elementscontent, such as: N, P, K and others organic maters.The result shows that there are 13 species of mangrove found. Five species areclassified into ‘pure’ mangrove and others are associate. Rhizophora apiculata (withImportant Value, IV, of 103.252 %) and Sonneratia alba (IV 99.663 %) are two species thathave high importance value (IV). In addition, the diversity of mangrove in Serangan islandis found to be low (diversity indices 0.791).Results of this study indicate that after reclamation, the mangrove ecosystem inSerangan is in unstable conditions.

Abstract

Technology of agroecologycal zonning is a land evaluation to using specific areaespecially in agriculture with friendly environment. Agroecologycal zonning based onfisically environment elements i.e., climate, physiography and landform, soil resources,vegetation and land use. Alternative commodities that will be devolloped based on socialeconomy factors. In area with stable land using (East and centre of Buleleng) thecommodities that will be choised : adaptive, profitable, and acceptability. In area with not yetstable land using (west of Buleleng) will be purposed with agroecologycal zonning as (1) atslopping area for suitable and profitable annual cropping, (2) at hilly area for multiplecropping, (3) in mountainous area with slope < 40% for multiple cropping and estate,whereas, if slope >40% and elevation >700 m over the sea level for plants conservation.

Abstract

A study on identification of trees species, their use as well as what the communitybelieve about them held in Peliatan Village, Ubud District, Gianyar Regency (Bali) onFebruary, 2005. The study was carried out by taking a walk along the roads or trails whichwere assessed for their potentials as tracking trails in this village while taking notes on thetree species observed. The trees then were determined their status, their use as well as whatthe community believe about them. Results of this study show that there were 148 kinds oftrees which have been identified on this village. From the use perspective, it was revealedthat these trees could give a wide range of benefits for the community of Peliatan as well asBali in general. Their use for decorations, provides shady spots, as well as uncultivated treeswere the highest in their proportion (22%). In addition, in this village they were alsoidentified 18% of trees which believed to provide a possitive or negative impacts to humans.Most of them (73%) were believed to be related to positive impacts to humans.

Abstract

The purposes of the research are to know the composition, distribution, and dominantspecies of vegetation at Batukaru forest conservation area (RTK-4). This research usedtransect method done by systematic plot sampling. Five transects were made, that was thedistance of 1 km each transect line. In each transect line there were 10 plots with the dictanceof 100 m each plot.The result of the experiment found 33 kinds of higher plant to cover the field on Gesingvillage and 18 kinds on Bukit Catu village, with Podocarpus imbricatus Blume is thedominant species on the both villages, with each the important value index of 88,82 % and99,47 % for the higher plant, so that species not stable yet. The lower vegetations thatidentificated on each location are 27 and 34 kinds of speciesDiversity Index on some level of plant growth at Gesing and Bukit Catu villages arearound 1,88 (sedling) – 2,77 (tree) and 1,77 (sedling) – 2,11 (tree), so the communitycondition is in the term of stable.

Abstract

Identification on rainfall pattern and water balance is very important for environtmentresearch, water resources development and agricultural planning. This study used statistical andThornthwaite and Mather (1957) method to analyse the water balance. The results show that wetseason at Denpasar take place on November up to April and dry season take place on May up toOctober in every years. Water surplus period at Denpasar take place for 4 months (January-April) in amount 496 mm. Water deficit period take place for 6 months (May-October) in amount298 mm.

Abstract

A research entitled “Inhibitid activity of plant fractination extract of Sembung Delan(Sphaeranthus indicus L.) to the causal agent of bacterial wilt on tomato” was carried out to find outthe active fraction of plant extract that responsible for bactericidal activity againt P. solanacearum L.,Results of this study showed that the crude extract of S. indicus inhibited the growth of P.solanacearum L. on PDA. It was indicated by the formation of inhibition zone around the disc loadedwith plant extract at concentration of 0 ppm, 10,000 ppm, 20,000 ppm, 30,000 ppm, 40,000 ppm, and50,000 ppm. From 17 fractions obtained from fractionation, fraction No. XV (eluted with ethylacetate 100%) contains three compunds with Rf value: 0.03; 0.23; 0.35 and fraction No. XVI (elutedwith ethyl acetate 100%) contains four compunds with Rf value: 0.03; 0.14; 0.17; 0.21, effectivityinhibited the growth of P. solanacearum L

Abstract

As part of our efforts to move towards sustainable development, it is very importantto encourage the tourism industry to be more environmentally conscious because itconsumes large amounts of resources. One way of achieving greater sensitivity is to identifybenchmarks for energy and water use and for other aspects of hotel operations like theamount of solid waste generated. Benchmarks can be defined using data from existinghotels. The research project focused on tourist accommodation on Southern Part of BaliIsland. It conducted a survey by mailed questionnaire of about 50% of the hotels on theisland. The questionnaire obtained annual data on several sustainability criteria that areenergy and water consumption, biodiversity conservation, resource conservation, cleaningchemical use, solid waste management and wastewater management. The data were usedto derive baseline and best practice thresholds to improve the performance of touristaccommodation on Bali Island.The benchmarks, both baseline and best practice standards were developed mainlyusing the study results which established the average and the average of the top 25% ofperformers. The average of the top 10% of performers was also considered in selecting thebest practice standard for indicators that required stricter standards. Within thebenchmarking process, Green Globe 21 standards and some other studies were also beingused for comparison purpose.In this survey, the difficulties were found in obtaining complete set of data from eachrespondents as well as gaining sufficient responses. Few hotels provided complete set ofdata. Data on energy and water consumption is the easiest to obtain, while data for otherindicators only provided by less than 75% of respondents. Most of the survey resultsshowed reasonable value compared to Green Globe 21 standards. Good performance oftourist accommodation in the survey was found in energy consumption indicator that theaverage and the average of the top 25% of performers were far stricter than the Green Globe21 standards. The study concluded with benchmarks recommendation for each indicatorthat can be applied to tourist accommodations in Southern Part of Bali Island.
