Abstract

As one group of Chironomidae Tanypodinae larvae can be used in biological assessment to detect the heavymetal pollution in aquatic environment, because they could show morphological changes due to the pollution. Thestudy was aimed to describe ligula deformities in Tanypodinae larvae in a heavy metal polluted lake. The study wasconducted in Mei to June 2014 at Lake Lido, West Java. The results showed that lead (Pb) concentration in LidoLake was quaite high, i.e. 0.08 0.19 mg/L. Ten of fifty-five collected Tanypodinae larve exhibited deformation in theirligulae. Index of severity of ligula deformation (ILSD) was 4.4 indicating the response of the Chironomidae larvae tolead pollution.Keywords: Chironomidae, heavy metal pollution, ligula deformities, Tanypodinae larvae

Abstract

This research was conducted at two different lakes in Jambi Province (Lake Sipin and Lake Teluk) to compare abundance of aquatic insect larvae (family: Chironomidae). Lake Sipin located close by the settlement and got many influences from anthropogenic activities. However, Lake Teluk got less anthropogenic disturbance. Both lakes have difference plants cover. The area around Lake Sipin was more open compared to Lake Teluk and it caused low transparency level in Lake Sipin. The transparency level of Lake Sipin was 58.62 cm whereas transparency level of Lake Teluk was 70.29 cm. The difference of this transparency level influenced Chironomidae Larvae abundance that was encountered. Larvae abundance which was found in Lake Sipin was 49 ind/m2, while larvae abundance of Lake Teluk was 374 ind/m2. The result showed that water transparency level, water colors and vegetation affected abundance of Chironomidae larvae. Keywords: abundance, chironomidae, water transparency

Abstract

Grouper net cages culture in Ekas Bay, East Lombok, Nusa Tenggara Barat were carried out for public income improvement. The net cages culture also potentially waste generate that can be harmful for those activity itself. Waste potential study from net cages culture was conducted to obtain information about Ekas Bay carrying capacity for culture activity. The information consists of physical and chemical properties of water (salinity, water temperature, dissolved oxygen, pH, ammonia, nitrite, nitrate, turbidity, and depth) as primary and secondary data. According to ammonia and nitrate concentration, the net cages culture activities could not suit the carrying capacity of Ekas Bay. The cage culture activity should be organize therefore can be economically and ecologically profitable furthermore ecologically sustainable.

Abstract

The residue of human activities and batik industrial waste water surrounding the river will be able to increase the accumulation of chromium and to disrupt macrozoobenthic communities in the river. The aims of this study was to assess the impact of human activities surrounding the river to the macrozoobenthic communities and the accumulation of chromium in Cimanuk Lama River, Indramayu District, West Java. The study has been conducted from April?May 2015 based on three times sampling at three different sampling stations. The result of this study shows that the chromium accumulated in the waters of all station still meet the standard quality ranging from 0,010-0,016 mg/l, but only station 1 fulfills the standard quality for chromium accumulated in the river sediment with the range of all stations was about 11,72-46,63 mg/kg. The results also show that the community index analysis describes the change of macrozoobenthic community at all stations caused by environmental pressure, especially at the station 2 which is indicated by the highest score of Family Biotic Index. The accumulation of the chromium in the waters and the change of macrozoobenthic community structure are mostly influenced by the use of the Cimanuk Lama river long for agricultural and fisheries activities, and also batik home industry.

Abstract

Study of spatial and temporal dynamics of zooplankton community structure in the Jakarta Bay. The purpose are analyzing the abundance, distribution, diversity, and dominance index with indicators of water quality spatial and temporal waters of Jakarta Bay. The research was conducted from July-October 2013. Sampling was done four times (July, August, September, and October). The water quality was analysed by Laboratory Productivity and Water Environment at Department of Resources Management, Faculty of Fisheries and Marine Sciences, Bogor Agricultural University. Zooplankton were analyzed using the method of enumeration (census SRC), in Micro Biology Laboratory Faculty. Based on the distribution patterns were its indicates that the landward dissolved oxygen (DO) is increasingly high, especially in August, September, and October, and increase the abundance of zooplankton as much as 1.3106 Ind/m3. DO with a high spatial concentration value reaches the range of 6.2-14.5 mg/L in Muara Marunda (Station 10), and increase the abundance of zooplankton as much as 5.1106 Ind/m3, with a majority composition of crustacea. Results of classification was diversity moderate, stable uniformity, and high dominance index.
