Abstract

The aim of this study was to observe the role of green trees to air quality in Denpasar City. Theresearch locations were at Cokroaminoto, Melati, and Cut Nyak Dien streets, during February 2006 to July2006. The sample plants were: angsanas, timber, and purple orchid leaf. Statistical analysis was conductedby applying double linier regression and anova test.The result showed that the highest total vehicle number (11.573 and 3.330), noise level (72,75 dB),air Pb concentration (0,313 ?g/m3), concentration of particulates (244 ?g/m3), temperature humidity index(27,45), wind speed (1,44 m/second), humidity (70,77 %), type and number of trees were observed atCokroaminoto street (26 types and 866 trees), whilst the lowest values were at Cut Nyak Dien street (7 typesand 121 trees). The highest temperature was observed at Melati street (29,25 oC) and the lowest was at Cut Nyak Dien street (28,51 oC). From the three places observed, the highest number of trees, height of tree, andwidth of crown were on angsanas tree (439 trees; 7,07 m; dan 8,7 m) and the lowest value was calculatedon purple orchid leaf (14 trees; 4,60 m; dan 5,8 m). On the other hand the highest leaf wide was on timber(131,550 cm2) and the lowest on angsanas (42,745 cm2). Concentrations of Pb leaves were calculated asfollows: angsanas 13,228 mg/kg; timber 13,208 mg/kg; purple orchid leaf 12,897 mg/kg, respectively.Statistical result showed that total plants, total motor cycle and total four wheels vehicles was notpartially or simultaneously affected air Pb and air dirt concentrations. Height of tree, width of leaves andwidth of crown did not affect leaves Pb concentration both partially and totally to leaves Pb. Based onlocation, it can be concluded that there was no difference of air dirt and air Pb concentration, but there isdifference in leaves Pb. Based on type of trees there was no significant difference on leaves Pb contentamong trees type, it means that every tree has similar ability in absorbing Pb.

Abstract

Mangrove ecosystems are crucial for the management of some coastal resources in Indonesia. Thisresearch used Landsat TM 1994, Landsat ETM+ 2002 with the purpose to know mangrove area change foreight years, mangrove density and accuracy of image as source of data to mangrove area in Benoa Bay. Fromimage analysis that using maximum likelihood method, the mangrove is classified into 3 classes i.e.:mangroves with high density, medium density and low density. For the ground check, used single plotmethod by using 6 trees.The extent of mangrove area in Benoa Bay were 447.69 ha in 1994 and 622.08 ha in 2002. Thechange of the extent of mangrove area during 8 years (1994 – 2002) increased by 174.41 ha. The area ofdensities in 1994, high density was 225.15 ha, medium density was 122.48 ha and low density was 130.05ha. In 2002, high density was 262.8 ha, medium density was 265.95 ha, and low density was 133.30 ha.Based on the regression analysis between mangrove density and the value of interpretation, the density ofmangrove in Benoa Bay which the criteria of high density is 364.723 – 466.311 tree/ha, medium density is237.738 - 364.723 tree/ha and low density is 186.944 – 237.738 tree/ha. The determination coefficient (r2)was 0.6312. Based on the regression analysis in 2002 used in interpretation of mangrove density in 1994,which the criteria of high density is 357.10 tree/ha –316.47 tree/ha, medium density is 273.29 tree/ha –316.47 tree/ha and low density is 252.98 tree/ha –273.29 tree/ha.The accuracy of the Landsat ETM+ 2002 for mangrove area classification in Benoa Bay was 90%.These values were above the acceptable limit of accuracy stated of 80 %, so that this classification accuracywas acceptable.

Abstract

ago. This traditional organization is socio-religious in nature based on the high spirit of cooperativework. It is very effective in support of the development of agriculture in Bali and it serves as an inheritanceof highly noble value so that it deserves to be conserved. Development in globalization and modernizationera indeed starts to push the subak culture either interms of pelemahan, pawongan, and parhyangan. SubakBulan pesedahan of Yeh Sungi Mengwi District Badung Regency whose irrigation water quite depends uponwater source has been disturbed since some of the beji water source of Baha village has been taken by otheruser.This study aims to know the impact of the taking of water from beji water source of Baha villageagainst the availability of irrigation water for Subak Bulan, the perception of subak members for the takingof the water and what is the relationship of the change of use of rice field in the Subak Bulan area with thetaking of water in the water source. The method employed is descriptive and corational method. Datacollecting by means of field observation in every water source and intake, interview with respondents usingquestionnaire for 48 respondents out of 303 Subak Bulan members.The findings show that the availability of irrigation water for Subak Bulan has its source from watersource and some of the water coming from the technical irrigation of Yeh Sungi quite fluctuates caused bythe change of season and the water debit from the upstream irrigation water because the location of SubakBulan is in the most downstream part of the irrigation network of Yeh Sungi. The availability of irrigationwater in each block (munduk) is not optimal. The perception of Subak Bulan to the taking of beji sourcewater of Baha village is that most of the villagers know this and they feel this is disadvantageous to them.There has been a change of land use in the area of Subak Baha as a result of water availability, economic,and social factor from 2000 to 2005 covering the area of 5.25 ha. The relationship between the change ofland use in Subak Baha and the taking of water in beji water source of Baha village shows negativecorrelation which is very significant at- 0.8875 caused by a number of factors among others being the time period for taking the water, opening ofnew roads, lack of water, land opening for settlement.It can be concluded that there is a lack in the availability of irrigation water of Subak Bahainequitably and it fluctuates as a result of the change of season. There is a need for replanning of blocks ofrice fields that need to be irrigated so that the source water of Subak Bulan and the interest of Baha villageare not dissatisfied therefore the source water should be well and fairly managed and preserved. The role ofthe government is also hoped in such a way that it serves as a mediator and makes regulations related to themanagement of the water resources available within the area of Subak Bulan.
