Abstract

Lokop is one of the villages in East Aceh which has a watershed in the Leuser Ecosystem. Human activities have the potential to disrupt the Trophic Status of Lokop River, such as the use of pesticides for agriculture, household waste and the use of potassium for fishing. It is necessary to research the quality of the waters in the Lokop River. The plankton community present in river waters can be an indicator of environmental pollution by analyzing the saprobic index. This study aims to determine the index of plankton diversity and water quality in the Leuser Ecosystem of the Lokop River through the saprobic index. The research was conducted at three stations. A sampling of plankton was taken in the form of a 10 cc filtrate and five replications were carried out for each study site. Water quality measurements include pH, TDS, Temperature, transparancy, depth, and current. 11 potential species can be used as pollution indicators in the Lokop River, namely Cladophora sp, Diatoma elongatum, Fragilaria capucina, Oedogonium sp., Gonatozygon sp, Lyngbya agardh, Melosira sp., Merismopedia punctata, Microspora sp, Pinnularia sp, Synedra ulna. The plankton diversity index is in the medium category. Based on the Saprobic Index, the level of pollution at the research site was not to lightly loaded of organic pollution and lowly loaded of organic pollution.Keywords:IsoprobikPlanktonBioindicatorLokop

Abstract

Ectoparasites which often attack tilapia include Trichodina sp., Dactylogyrus spp., Gyrodactylus spp., and Epistylis spp. This research aims to determine the types, prevalence, and intensity of ectoparasites found on tilapia (Oreochromis niloticus) in the floating net cages of Batanghari River, Jambi. The research was conducted from February through March 2020. A survey method is carried out through direct sampling at the study site to identify the tilapia ectoparasites. The sampling technique is done using random sampling. Ninety fish were taken for parasite inspection at the Fish Quarantine, Quality Control, and Safety of Fishery Products Class I Jambi Station. The observations found three types of ectoparasites namely Dactylogyrus sp., Epistylis sp., and Oodinium sp. The highest ectoparasite prevalence rate was found from the species Epistylis sp. with a value of 37.7% and an intensity value of 24.7 ind/fish. The prevalence of Dactylogyrus sp. was 26.6% and an intensity value of 1.3 ind/fish. The lowest prevalence value was from Oodinium sp. with a prevalence value of 7.7% and an intensity value of 3.2 ind/fish. The prevalence and intensity values of tilapia ectoparasites based on their locations were 56.6% and 23 ind/fish (station I), 50% and 18.6 ind/fish (station II) and 43.3% and 17.6 ind/fish (station III). The types of ectoparasites found on tilapia in this study were Epistylis sp., Oodinium sp., and Dactilogyrus sp. The parasite with the highest prevalence and intensity found during the survey was Epistylis sp.Keywords:EctoparasitesTilapiaPrevalenceIntensityFloating net cages
