Abstract

Abstract Toxicity is the ability of a material to cause adverse  effects when it hits the surface or body of the test organism. One of the test materials that can be used is the microalgae type Cyclotella sp. The purpose of this study was to study the ability of Cyclotella sp. as a test material meets the requirements for heavy metal toxicity tests. The growth phase of the microalgae Cyclotella sp. Observations were carried out for 17 days to see all the growth  phases of Cyclotella sp. This result indicate that there are four living phases of Cyclotella sp. It comprises of phases lag, an exponential phase, stationary phases and phases leading to death. Cyclotella sp. qualified as a test biota for a heavy metal toxicity test using phytoplankton, according to Asean- Canada Cooperative Programme on Marine Science Phase II. This is seen from the growth of cell density that exceeds the minimum limit on the fourth day of inoculation growth curve or at the beginning of an exponential phase with density of cell 123,5 x 106 cell.mL-1.The results of the literature study showed that Cyclotella sp. can be used as biota for toxity test. Keywords: Toxicity test, Cyclotella sp., Exponential, Density, Phytoplankton.

Abstract

                      ABSTRACTHeavy metals in water can be included in hazardous and toxic materials in high concentrations. Mercury (Hg) and Chromium (Cr) are heavy metals that are dangerous when entering water bodies and will affect aquatic organisms. Microalgae are aquatic organisms that have a significant role as the basis of the food chain, as well as one of the parameters of the fertility level of water which is the primary concern because it has a high risk of being exposed to aquatic organisms such as microalgae. One of the microalgae is Dunaliella sp. This research was conducted to determine the ability of Dunaliella sp. as a condition for biota to test heavy metal toxicity. Observations of the growth of Dunaliella sp. were carried out for 14 days to see the entire growth phase of Dunaliella sp. The results of this study show that there are five life phases of Dunaliella sp., namely the lag phase, the acceleration phase, the exponential phase, the retardation phase, and the death  phase.   Dunaliella sp. qualified  as a test biota for heavy metal toxicity testing according to the Asean-Canada Cooperative Program on Marine Science Phase II. The cell density of  Dunaliella sp. on day four or at the beginning of the exponential phase is 1.36 x 10 6 cells/ ml. It can be seen that the cell density of Dunaliella sp. exceeds the minimum limit (1x106 cells /ml).Keywords : Dunaliella sp., , Exponential, Density  Phytoplankton, Toxicity test

Abstract

                       ABSTRACTMicroalgae have an important position as primary producers which have the first trophic level in the food chain of aquatic ecosystems. One of them is Dunaliella sp. Lead and cadmium are non-essential heavy metals that are toxic to aquatic organisms. The purpose of this study was to determine the growth of Dunaliella sp. for heavy metal toxicity tests. Observations were made for 14 days to see all growth phases of Dunaliella sp. The results showed that there were 4 growth phases of Dunaliella sp. namely the lag phase, the exponential phase, the stationary phase and the dying phase. The  microalgae Dunaliella sp. met the requirements for heavy metal toxicity test on day 4 or in the exponential phase and the minimum limit for the cell density of the test biota was (1 x106 cells/ml) according to ACCPMS -11 (1995).Keywords : Dunaliella sp., Toxicity test,  Exponential phase, Phytoplankton,       Heavy Metals

Abstract

Pengembangan budidaya ikan air tawar membutuhkan bantuan dari pihak perbankan khususnya aspek permodalan. Kegiatan ini bertujuan untuk meningkatkan pemahaman pegawai bank dalam budidaya ikan air tawar sehingga diharapkan mampu melayani nasabah pelaku usaha ikan air tawar dengan lebih baik. Metode pelatihan menggunakan ceramah, diskusi dan field trip ke lokasi usaha perikanan air tawar. Hasil pendidikan profil bisnis komoditas ikan air tawar menunjukkan peningkatan pemahaman peserta terhadap seluk beluk budidaya ikan air tawar. Melalui kegiatan ini diharapkan pengembangan budidaya ikan air tawar terus berkembanga di masa yang akan datang.

Abstract

Ikan tambakan (Helestoma sp.) merupakan ikan air tawar yang bernilai penting. Belum adanya penelitian terkait pola pertumbuhan dan faktor kondisi ikan tambakan (Helestoma sp.) di Danau Panjang. Pengambilan sampel dilaksanakan pada bulan Oktober 2022 dengan menggunakan alat tangkap berupa jaring, pancing, dan perangkap di Danau Panjang Desa Lubuk Siam, Riau. Data dianalisis menggunakan aplikasi Ms. Excel dari hasil analisis pola pertumbuhan ikan (n=32) menunjukan nilai a = 0,0079 dan nilai b = 3,3778, R2 sebesar 0,9554. Pola pertumbuhan ikan tambakan di Danau Panjang bersifat alometrik positif. Faktor kondisi ikan tambakan relatif baik dengan nilai berkisar 0,769 hingga 1,192.

Abstract

In Indonesia, the study of biomarkers is still very few because not many biomarkers are understood in various inland public waters here. The research location was at the Koto Panjang Reservoir as the experimental location and the Sei Tiban Fish Seed Center as the control location. The fish tested were carp and tilapia. Sample analysis was carried out in a certified laboratory at Construction Materials Laboratory, Department of Public Works, and Genetics Laboratory, Universitas Riau. The biomarkers studied were LSI, GSI and MT, and heavy metals observed were Cd, Pb and Hg. The research method was Experimental Design. Based on the statistical test, there was no difference in the LSI value of tilapia in the treatment group and tilapia in the control group (p = 0.187; p > 0.05), while it was different from goldfish (p = 0.0000; p < 0.001). In GSI, both of tilapia and carp showed significant differences (p = 0.0010; p < 0.010) and (p = 0.0060; p < 0.010). The tilapia and carp-treated livers showed the presence of MT while not in the control fish. This indicates that MT can be used as a biological marker of heavy metal exposure compared to GSI and LSI.
