Febriansyah, Satria Cahya (2019) Evaluasi Kualitas Air Kolam Lele Dumbo (Clarias gariepinus) Beberapa Umur di Desa Gondosuli, Kabupaten Tulungagung Menggunakan Plankton sebagai Bioindikato. Sarjana thesis, Universitas Brawijaya.
Abstract
Penelitian ini bertujuan melakukan evaluasi profil kualitas air berdasarkan parameter fisika kimia dan plankton sebagai bioindikator pada kolam ikan lele berbagai umur di Desa Gondosuli, Kabupaten Tulungagung. Jenis penelitian adalah ex post facto dengan melakukan pemantauan parameter fisika dan kimia air serta struktur komunitas plankton pada kolam kontrol, kolam dengan ikan lele umur < 1 bulan, 2-3 bulan dan 3-4 bulan masing-masing 3 ulangan. Air tiap kolam diukur sifat fisika kimia air meliputi suhu air, konduktivitas, pH, kecerahan, DO, BOD dan turbiditas. Plankton yang didapat di identifikasi dan di analisis untuk penentuan struktur komunitas (INP), dan indeks biotik (H’, TDI, %PTV) untuk kualitas air. Hasil pengukuran setiap parameter fisika kimia air antar lokasi dianalisis secara statistik inferensial menggunakan uji beda. Interaksi antara struktur komunitas plankton dan kualitas fisika kimia air dianalisis menggunakan Biplot. Hasil penelitian menunjukkan bahwa, kolam dengan umur lele yang semakin tua telah berdampak pada penurunan kualitas air. Hal ini ditunjukkan oleh tingkat pencemaran bahan organik yang semakin tinggi dicerminkan oleh kadar BOD dan turbiditas yang tinggi serta nilai DO yang rendah. Perairan kolam lele berdasarkan nilai H’ dari plankton menunjukkan belum terjadi pencemaran bahan organik. Berdasarkan nilai TDI, perairan kolam lele termasuk kategori status buruk (hyper-eutrophic), dan berdasarkan indeks %PTV pada kolam dengan umur ikan lele 2-3 dan 3-4 bulan tergolong tingkat pencemaran bahan organik yang tinggi
English Abstract
This study aims to evaluate the water quality profile based on the parameters of physical chemistry and plankton as bioindicators in catfish ponds of various ages in Gondosuli Village, Tulungagung Regency. This type of research is ex post facto by monitoring the physical and chemical parameters of water and the structure of the plankton community in control ponds, ponds with catfish aged <1 month, 2-3 months and 3-4 months each with 3 replications. Water samples for each pond were measured the physics chemical water quality included water temperature, conductivity, pH, water transparency, DO, BOD and turbidity. Data from the identification and calculation of plankton obtained were analyzed for the determination of community structure (K, F, KR, FR, INP), and biotic index (H ', TDI and% PTV) for water quality. The results of measurements of each physico-chemical parameter between locations were analyzed statistically inferentially using a different test. The interaction between plankton community structure and the physical quality of water chemistry was analyzed using biplots. The results showed that, ponds with the age of catfish that were ready to harvest had an impact on decreasing water quality. This is indicated by the high level of organic matter pollution which is reflected by high BOD and turbidity levels and low DO values. Catfish pond waters based on the value of H 'from plankton show that organic matter has not yet occurred. Based on TDI values, catfish pond waters are categorized as poor status (hypereutrophic), and based on the index of% PTV in ponds with catfish age 2-3 and 3-4 months classified as high levels of organic matter pollution
