Abstract

Coral reef ecosystem has become a centre of interest because of the development of marine tourism development,coral fragment trade, and other activities that are able to destroy coral reef ecosystem. ALOS with AVNIR-2 sensor wasselected because it has 3 visible spectrums which have the ability of penetration into water column, also it have highenough of spatial resolution i.e.10 meters.The aims of this research are: 1) to identify the level of accuracy of ALOS satellite image in activity for coral reefdistribution mapping and 2) to identify the general condition of coral reefs in around Badung Strait.Preliminary processes of image processing are geometric correction and atmosphere correction. Water columneffect was reduced by Lyzenga Algorithm. Five classes were determined by multispectral classification process e.i. coral,vegetation, sand, rubble of coral and substrate. Ground check was done to identify the accuracy level. The methodaccuracy by Lillesand and Kiefer was used in this research.The result of accuracy test shows that classification accuracy was 87.16% for overall accuracy. Results of imageinterpretation show that live coral in around Badung strait is estimated to have about 141,056 hectares width. It wascovering Denpasar Regency in the east and south-east side of Serangan Island with the fringing reef type; KlungkungRegency in the west side of Lembongan Island with the fringing reef type and in the south side with the platform type,while in Gianyar Regency was not found the coral reef distribution.

Abstract

Land use is one of the macro parameters that affects water quality in a watershed. The Cimanuk watershed which is dominated by agricultural land use and settlements has encountered a decline in water quality. There are eight parameters including pH, TDS, TSS, Nitrate, Phosphate, Sulphate, BOD, and COD analyzed to evaluate water quality utilizing the Pollution Index (IP) method. This research has provided a clear understanding of the status of water quality in the Cimanuk watershed based on six monitoring points carried out at the start of the 2018 rainy season. Overall, the IP values obtained ranged from 2.05 to 5.96 with the lightly polluted category at points A, B, C, D, and E, while for point F it was in the moderately polluted category. The key parameters that have the most influence on water quality pollution are Nitrate, Phosphate, Sulphate from fertilization activities in agricultural land, while runoff from settlements contribute to increasing parameters of BOD and COD. These results can be beneficial for sustainable management of water and land resources in the Cimanuk watershed.

Abstract

Dengue Hemorrhagic Fever (DHF) disease represents one of the important public health problems in Indonesia and it often generates an extraordinary occurrence of vast number of deaths. The research aims to know environmental factors and public behaviors which have relationship to the existence of mosquitoes larvae in the work area of North Kuta Public Health Centre. The result of this research shows that the environmental factors which are related to the existence of mosquitoes larvae are air humidity (p=0.000), the existence of obstructive drainage (p=0.000) and the existence of containers (p=0.000). The public behaviors which are associated with the existence of mosquitoes larvae are attitude (p=0.001) and the actions of people (p=0.000). In conclusion, the environmental factors which are related to the existence of mosquitoes larvae are air humidity, the existence of obstructive drainage and the existence of containers. The public behaviors which are associated with the existence of mosquitoes larvae are attitude and the actions of people. It is suggested that the people should participate more in the prevention of DHF disease by removing the nests of mosquitoes, and the Public Health Departement should put more attention to the environmental factors which are associated with the existence of mosquitoes larvae.
