Abstract

Mikroplastik di perairan menjadi permasalahan yang cukup serius bagi organisme perairan. Organisme filter feeder seperti kerang memiliki resiko yang cukup besar untuk mengakumulasi mikroplastik ke dalam tubuhnya. Salah satu jenis organisme tersebut ialah kerang manila (Venerupis philippinarum) yang banyak terdapat di Perairan Maccini Baji, Kecamatan Labakkang, Kabupaten Pangkajene Kepulauan, Sulawesi Selatan. Penelitian ini bertujuan untuk mengetahui keberadaan dan konsentrasi mikroplastik yang terdapat pada daging kerang manila (Venerupis philippinarum). Pengambilan sampel kerang dilakukan dengan metode sampling acak berlapis (stratified random sampling), sehingga diperoleh sampel sebanyak 118 ekor. 118 sampel kerang manila tersebut kemudian dibagi menjadi tiga kelompok ukuran panjang cangkang kerang yaitu kelas A (3,11 – 3,86 cm), kelas B (3,87 – 4,82 cm), kelas C (4,83 – 6,01 cm). Pengamatan partikel mikroplastik dilakukan dengan menggunakan mikroskop stereo. Hasil pengamatan menunjukkan sebanyak 61 sampel (51,69%) kerang manila mengandung partikel mikroplastik. Mikroplastik yang ditemukan berbentuk fiber dan fragmen, dengan warna dominan biru, hitam, dan transparan. Ukuran mikroplastik yang ditemukan berkisar antara 0,090 – 4,919 mm. Nilai rata-rata konsentrasi mikroplastik pada masing-masing kelompok ukuran panjang cangkang kerang secara berurutan yaitu 0,6129 item/g, 0,6303 item/g, dan 0,2198 item/g. Kata kunci: Fiber, kerang manila, konsentrasi mikroplastik, Maccini Baji, Venerupis philippinarum.

Abstract

The accumulation of organic matter at the bottom of the pond greatly affects nutrient metabolism, feed efficiency, growth and productivity in giant tiger prawn cultivation. One of the causes is improper pool bottom construction The purpose of this study was to compare the growth performance and efficiency of protein utilization in giant tiger prawns consuming artificial feed supplemented with multi-enzymes and reared in tarpaulin ponds constructed between not and using the faecal chamber (FAMBER) or the space of metabolic waste and unconsumptioned feed (SOMECOF) at the bottom of the pond with a recirculating aquaculture system (RAS). A tarpaulin pond with a diameter of 3 m and a height of 100 cm filled with 80 cm of seawater. The tarpaulin pond is equipped with a transparent plastic roof, seawater and aeration installation, and a filter in the water pump tank. The average body weight of the experimental prawn used were 8-9 g. The feed given is pellet type artificial feed supplemented with multi-enzymes at a dose of 30 cc/kg of feed. The frequency of feeding were four times a day, namely at 07:00; 12:00; 17:00 and 22:00 with a dose of 5%. The parameters measured were growth performance including growth, condition factors and feed efficiency, while the efficiency of protein utilization included protein content, protein efficiency ratio, amino acid profile, index and score of essential amino acids of feed and experimental prawn. Data analysis was done descriptively. The results showed that all parameters of growth performance and efficiency of protein utilization in tiger prawns reared in tarpaulin ponds using FAMBER were better than those without FAMBER. Based on the results of the study, it was concluded that keeping giant tiger prawns in a tarpaulin pond using a FAMBER is better than not using a FAMBER.

Abstract

As a filter feeder, windowpane oyster, Placuna placenta, which lives as a sedentary animal is very appropriate to be used as an eco-sentinel organism in marine bio-monitoring campaign.  The study of lead (Pb) content in the tissue and shell of P. placenta was conducted in coastal waters of Mandalle, Pangkajene Kepulauan District, South Sulawesi.  A hundred of oysters were collected from coastal waters of Mandalle.  Morphometry parameters which were length, high, width, and dry weight of tissue were measured in the laboratory.  Those parameters were used for determination of Condition Index (CI).  Metal was analyzed by Atomic Absorption Spectrometry.  The results showed that the contents of Pb in tissue and shell were 0.021 and 0.014 mg/kg DW (dry weight) respectively.  The concentration of Pb in tissue was not overreach by BPOM 2009 Number Hk.00.06.1.52.4011 of 1.5 mg / kg DW (dry weight).  After calculating Maximum Tolerable Intake (MTI), we found that MTI was 7.79 kg/day.  In terms of marine monitoring campaign, we can theoretically use the CI as a morphological biomarker.  After calculating the relationship between Pb in tissue and shell, we found that the value of CI was not correlated significantly with Pb content in tissue and shell.  However, the correlation coefficient between Pb in tissue and CI was stronger than that in the shell.  The potential of CI of windowpane oyster as a morphological biomarker was discussed.Keywords: Placuna placenta, lead, MTI, morphological biomarker
