Abstract

Penelitian ini bertujuan untuk menganalisis kuantitas kandungan logam berat jenis timbal (Pb), kadmium (Cd), besi (Fe), merkuri (Hg), dan minyak solar di estuaria Krueng Cangkoi. Pengambilan sampel dilakukan di Krueng Cangkoi, Desa Padang Seurahet, Kecamatan Meureubo, Meulaboh, Aceh Barat. Analisa data dan proses penelitian dilaksanakan di Laboratorium Badan Riset dan Standardisasi Industri Daerah (BARISTAND) Kota Banda Aceh pada bulan Desember 2014 sampai dengan Januari 2015. Penelitian menggunakan metode purposive sampling dan data diperoleh berdasarkan uji Spektrofotometri Serapan Atom terhadap kandungan logam berat jenis Pb, Cd, Fe, Hg, dan minyak solar di 5 (lima) titik sampel. Di dapatkan hasil tingkat kandungan logam berat Cd (0,14 mg/L) dan Fe (0,56 mg/L) di Krueng Cangkoi telah melampaui ambang batas baku mutu berdasarkan Peraturan Pemerintah No: 82/2001 yaitu 0,01 mg/L pada Cd dan 0,3 mg/L pada Fe. Hasil indeks pencemaran di Krueng Cangkoi didapatkan nilai indeks pencemaran Fe yaitu 1,76 mg/L tergolong cemar ringan dan nilai indeks pencemaran Cd yaitu 3,91 mg/L tergolong cemar sedang berdasarkan baku mutu KeMenLH No: 115/2003.The objective of research to analyzed quantity of heavy metals types of: lead (Pb), cadmium (Cd), iron (Fe), mercury (Hg) and diesel fuel in estuaries of Krueng Cangkoi. Sampling was conducted on December 2014 until January 2015 in estuaries Krueng Cangkoi, Meulaboh, West Aceh. The data analyzed and research process at the Laboratory Research and Standardization Industry (BARISTAND) Banda Aceh. The research used purposive sampling method and the data was obtained by Atomic Absorption Spectrophotometry method test for heavy metal content types of: Pb, Cd, Fe, Hg and diesel fuel at 5 (five) sites sampling. The results of level of heavy metals Cd (0,14 mg/L) and Fe (0,56 mg/L) in Krueng Cangkoi has exceeded the quality standard threshold base on Government Regulation No: 82/2001 was 0,01 mg/L in Cd and 0,3 mg/L in Fe. The results of pollution index in Krueng Cangkoi obtained pollution index values of Fe was 1,76 mg/L classified of lightly-polluted and pollution index values of Cd was 3,91 mg/L classified of moderately-polluted based on quality standard of KemenLH No: 115/2003.

Abstract

Beberapa spesies ikan tuna mulai terancam ketersediaannya. Upaya untuk mewujudkan pemanfaatan yang optimal dan berkelanjutan sangat dibutuhkan, sehingga perlu dilakukan monitoring, evaluasi dan perbandingan terhadap pemanfaatan tuna sirip kuning. Tujuan penelitian untuk mengkaji dan meganalisis pola pertumbuhan dan mortalitas tuna sirip kuning di PPI Ujong Baroh. Penelitian menggunakan metode deskriptif dengan pendekatan kuantitatif. Pengamatan dan pengukuran sampel tuna sirip kuning dilakukan secara langsung dari hasil tangkapan nelayan. Selanjutnya pengumpulan data tuna sirip kuning meliputi jumlah hasil tangkapan serta pengukuran karakter morfometrik yaitu panjang cagak (FL). Hasil penelitian menunjukkan koefision ukuran panjang maksimum (L∞) yaitu sebesar 97,65 cm, dengan pendugaan panjang tuna sirip kuning pertama kali tertangkap (LC) pada ukuran panjang cagak (FL) 56,43 cm.  Nilai laju pertumbuhan (K) sebesar 0,80 pertahun, laju mortalitas total (Z) sebesar 0,26 pertahun, mortalitas alami (M) sebesar 0,76 pertahun, mortalitas penangkapan (F) sebesar -0,50 pertahun. Rata-rata ikan tuna sirip kuning yang tertangkap berukuran kecil dan belum matang gonad (Lc<Lm) dengan tingkat pertumbuhan lebih cepat serta kematian alami lebih besar dari pada penangkapan. Kegiatan penangkapan tuna sirip kuning yang di daratkan di PPI Ujong Baroh merupakan perikanan skala kecil dengan nilai eksploitasi (E) sebesar -1,94 pertahun yang tegolong under fishing berdasarkan dari nilai M (F<M).  Several species of tuna fish are starting to face threats to their availability. Efforts to achieve optimal and sustainable utilization are crucial, requiring monitoring, evaluation, and comparison of the utilization of yellowfin tuna. The research aim is to examine and analyze the growth and mortality patterns of yellowfin tuna in Ujong Baroh Fish Landing Base (PPI). The method in this research uses a descriptive method with a quantitative approach. The observation and measurement of yellowfin tuna samples are directly conducted from the fishermen's catch. Data collection of yellowfin tuna includes the quantity of catches and measurements of morphometric characteristics, specifically fork length (FL). The research results show that the maximum length coefficient (L∞) is 97,65 cm, with an estimated length at first capture at a fork length (FL) of 56,43 cm. The value of growth rate (K) of 0,80 per year, total mortality rate (Z) of 0,26 per year, natural mortality (M) of 0,76 per year, fishing mortality (F) is -0,50 per year. On average, the yellowfin tuna caught are small and immature gonads (Lc<Lm) with a faster growth rate and greater natural mortality than those caught in the fishery. The fishing activity of yellowfin tuna landed at PPI Ujong Baroh are small-scale fishery with an exploitation value (E) of -1.94 per year which is classified as under fishing based on the M value (F<M).
