Abstract

The water and sediment caused by heavy metal has become a major problem in coastal areas. Heavy metals released into the water binds to particulate matter, accumulate into sediments and its predicted by the pollution assessment method. The aims of this research was to investigate the distribution and contamination levels of Pb in water and sediments of Bondet Estuary. Water and sediments samples were collected from four stations in September 2020. The monitoring data of water quality status, contamination factor (CF), and geo-accumulation index (Igeo) were used to provide a assessment of the Pb contamination. The concentration of Pb in water at all stations (0,024-0,031 mg/L) was higher than the standard surface water, with the status is lightly polluted (class B). CF index for all stations 1 ≤ CF <3 indicates moderate Pb contamination in the sediment, while Igeo for each station is <0, which means no contamination. Overall when referring to some guidelines for sediment standards, Pb concentrations at all stations were still below the standard value for sediment. This study provides a basis for assessing future conditions and risks, so that it can contribute to the management and evaluation of heavy metal contamination in the Bondet Estuary.

Abstract

Pesticides has been widely used in pest eradiction in agriculture sector. The types of pesticides are used to kill grass (herbicides), fungi and bacteria (fungicides), and insects (insecticides). In general, those pesticides are contain toxic compounds, such as dichlorodiphenyl trichlorethane (DDT), dieldrin, and polychlorobiphenyls (PCB) which are lipophilic, persistent, and difficult to degrade. In general, fresh waters such as rivers are more at risk of pollution due to pesticide residues that enter through runoff. The pesticides residues of the nearby rivers can easily affect the water quality, sediment as well as causing toxic effects on non-target organisms through the food chain. The method in this paper refers to several research results that have been carried out, by providing an overview of pesticide residue pollution in rivers. The results showed that pesticide residues mostly contaminated rivers in China, with DDT and hexachloro cyclohexane (HCH) being the most commonly found and studied species. Several rivers in China have concentrations of DDT and HCH beyond the highest concentration levels in both water, sediments and aquatic organisms.Keywords : Pesticide, Pollution, River

Abstract

Desmopuntius gemellus is a native species of peat swamp waters in Southeast Asia. This fish is economically important value for the local community, for example as consumption fish and as bait to catch carnivorous fish. Until now there has been no management effort to protect the sustainability of the fish. Ecobiology studies are needed as initial information in managing this fish. Samples were collected from primary and secondary canal stations at the palm oil plantation in Penawartama District, Tulang Bawang Regency during October 2019 to January 2020. A total of 1,088 fish samples were collected by using lift net, with the most distribution in the secondary canal. Main component analysis shows that secondary canal stations are more characterized by temperature parameters. And the primary canal is characterized by depth, brightness, current, and dissolved oxygen.

Abstract

Abstract This time fish farmers often face constraints on the high price of commercial feed which results in low profits for the farmers. One solution to reduce artificial feed is periodic starvation. Starvation can reduce and increase feed efficiency while increasing production and fish can grow equally without fasting. The purpose of this study was to determine the growth and survival of periodically fasted tilapia (Oreochromis niloticus) in Bedeng Munir Village, South Pagar Alam. The method used in fish farming consisted of two treatments, that is P0: control and P1: fasting treatment (fish were given commercial feed for 4 days and fasted for 1 day). The parameters observed were absolute length growth, absolute weight growth, total feed consumption, feed efficiency, survival, and water quality. The results showed that the P1 treatment produced the highest absolute weight growth of 16.5 g, the highest absolute length growth was 1.35 cm, the lowest amount of feed consumption was 1540 g, the highest feed efficiency was 204.94%, the survival rate was 89. %,. While water quality in both the treatment is still in the range of tolerance for tilapia as temperature 21.4 to 24.2 0C and pH 7.6 to 8.1.KeywordsGrowth, tilapia, starvation, survival.
