Abstract

Radar is able to provide information about extreme weather observations in the form of heavy rain, so it is important to find the level of accuracy of the radar in providing extreme weather information. So that with accurate data disaster mitigation can be done by creating an early warning system using radar data in order to minimize the impact that will occur. Comparative analysis of the estimated rainfall events on the radar with surface observation data shows a good level of accuracy, but the blankness of the data on the radar due to damage thus influences the decision making of the forecasters when providing extreme weather information quickly to the public. By knowing the radar accuracy level is quite good in estimating rain events, BMKG can provide weather information in the form of appropriate early warning so that people can anticipate extreme weather events

Abstract

Batur Lake is one of the lakes located in the Kintamani sub-district, Bali. This lake has abundant biodiversity, one of them is Red Devil fish (Amphilophus sp) which is a competitor of native and introduced fish. The research aims to find out the pattern of growth, size structure, and the physical and chemical conditions of waters. The method used was descriptive quantitative by using two trapping devices that were fishing rods and nets. Calculation results showed that a wide range of growth patterns of Red Devil (Amphilophus sp) fish on both trapping devices (fishing rods and nets) were grouped (Id<1). The highest sized structure value on the trapping devices (fishing rod) found in the water of Trunyan Village that was total length (TL) of 9,3 cm, Standard length (SL) of 7,3 cm, and weight: 16,5 gr. On the trapping devices (net) the highest value was found in the water of Songan Village that was total length (TL) of 13,5, SL of 11,1, and weight: 48,8 gr. The growth patterns of Red Devil (Amphilophus sp) fish based on length and weight analysis showed that were partly positive allometric and partly negative allometric. The result of the water quality measurement in the water of Batur Lake was about 26,3°C – 29,1°C (temperature), 5,36 mg/L – 6 mg/L, (DO), 7,2 – 7,8 (pH), and 87,1 cm – 147,8 cm (brightness).

Abstract

The Unda River (Tukad) is the second largest river in Bali Province after the Ayung River. The Unda River has been used for various activities, such as tourism activities for white water rafting and agricultural irrigation activities. In addition, Unda River water is planned to be used as a raw water source in the planned construction of the Bali Cultural Center (PKB) which is planned to be built in the lower reaches of the Unda River. Therefore, it is necessary to conduct research related to the water quality of the Unda River, especially in the Lower Unda River. Water quality analysis refers to class II water quality standards according to the Bali Governor Regulation Number 16 of 2016. Meanwhile, the analysis of water quality status uses the pollution index (IP) according to the Decree of the Minister of the Environment Number 115 of 2003. The results of the analysis show that water quality parameters that exceed the highest quality standard is downstream (sampling point 3) with 4 (four) parameters, namely Total Dissolved Solid (TDS), chemical oxygen demand (COD), total coliform and fecal coli. While the sampling points 1 (one) and 2 (two), the parameters that exceed the quality standard are total coliform and fecal coli. In addition, the results of this study also show that the pollution index value downstream is increasing, where at sampling point 1 which is a DAM location has a pollutant index of 3.78 (light pollution) and at sampling point 2 of 6.27 (moderate pollution) and at sampling point 3 of 7.67 (medium polluted).

Abstract

Sanur Beach is one of the tourist destinations that is often visited by national or international tourists. The number of tourism activities can increase pollutants entering the waters, one of which is heavy metals. Heavy metal content in waters can come from various sources of activity, one of which is lead (Pb) and cadmium (Cd). Seagrass E. acoroides are found in the waters of Sanur Beach. Seagrass can absorb heavy metals because it interacts directly with the column to absorb metal ions in the water. The purpose of this study was to determine the value of bioconcentration and translocation factors for the heavy metal content of cadmium (Cd) and lead (Pb) in E. acoroides seagrass in the waters of Segara Ayu Beach, Semawang Beach, and Mertasari Beach and to determine their suitability with the quality standards of the Bali Governor Regulation. No. 16 of 2016, Permenkes RI. No. 32 of 2017 and SEPA of 2000. Sampling was carried out by purposive sampling method and the data obtained were analyzed using quantitative descriptive methods and methods. The highest bioconcentration factor in cadmium (Cd) leaves was at station II, namely 1.91 mg/kg, and the lowest was at station I with a value of 0.62 mg/kg. The highest bioconcentration factor in lead (Pb) leaves was at station II, namely,0.47 mg/kg and the lowest was at station I, namely 0.08 mg/kg. The highest bioconcentration factor in cadmium (Cd) roots was at station II, namely 1.23 mg/kg, and the lowest was at station III, namely 0.73 mg/kg. The highest bioconcentration factor in lead (Pb) root was at station II, namely 0.22 mg/kg and the lowest was at station III, namely 0.10 mg/kg. The highest translocation factor for cadmium (Cd) was at station II, namely 1.55 mg/kg, and the lowest at station I was 0.53 mg/kg, while for lead (Pb) the highest was found at station III, namely 2.45 mg/kg and the lowest was at station I which was 0.49 mg/kg. The content of cadmium (Cd) and lead (Pb) in seagrass does not meet the quality standards of the Bali Governor Regulation No. 16 of 2016, Permenkes RI. No 32 of 2017, but in sediments according to SEPA 2000.

Abstract

Cangkir and Pakerisan are two rivers which are located in Gianyar-Bali Regency, each with a length of 23 km (54.58 km2 of watershed area) and 34.5 km (58.33 km2 of watershed area). These two rivers empties into Lebih Beach that each has a species diversity and abiotic factors. At the upstream of the rivers were occupied by tourism activities that can affect the ecosystem. This study aims to determine the diversity and distribution of macroinvertebrates in the two rivers. Sampling stations were situated at upstream area with 5 stations and 3 replications (15 points) on each river. Sample identification was carried out at the Laboratory of Water Resources Management, Faculty of Marine Science and Fisheries, Udayana University. It was found four species, namely Littorina carinifera, Melanoides torulosa, Parathelphusa convexa, and Bellamya javanica. At upstream of Cangkir and Pakerisan rivers had species of random category distribution pattern with the Morisita Distribution Index value that equal to one. Physical and chemical factors had a major influence on the ecological conditions of the two rivers. The environmental conditions that consisting of substrate type, several physical and chemical parameters were unable to support the life of various biota species found in these aquatic ecosystems.
