Abstract

The development of mature fruit Bruguiera gymnorrhiza (large mangrove leaf) are green color change (age 70 Daf), green-purple (age 80 Daf) and ended up being a full purple (90 Daf). Fruit is also experiencing accretion diameter, except for the tip (tip:1,14 to 1,13 cm; middle: 1,63 to 1,69 cm; base: 1,23 to 1,25 cm), lengthy (16,51 to 18,81 cm) and reduction weight (30,08 to 27,14). Increasingly fruit age, the harder texture (173,50 to 191,50 N). it was distinctive fruit flavors and slightly bitter tannins, so the fruit can not be consumed directly. The fruit (tip, middle and base) that have cell development is endocarp and mesocarp. Cells in the endocarp shape are a hexagon (tetrahedron) irregular, in Mesocarp cells undergo renewal and there is also a prism shape. It is evenly distributed throughout the cell wall thickening section (lacunnar). Types include parenchyma and collenchyma tissue. At the same eksocarp, endocarp cell shape, with tight cell structure, composed of epidermal cells and hypodermic. Cells of the epidermis have stomata.Keywords: B. gymnorrhiza, macroscopic, mature fruit, microscopic

Abstract

Salah satu bahan pencemar pada perairan adalah logam berat Timbal (Pb). Organisme perairan merupakan kelompok organisme yang pertama kali mengalami dampak secara langsung dari pengaruh limbah atau pencemaran logam berat di perairan. Salah satu organisme perairan yang menerima dampak langsung pencemaran logam berat adalah tanaman mangrove. Penelitian ini bertujuan untuk mengetahui akumulasi logam berat timbal (Pb) pada jaringan akar, batang, daun dan buah Avicennia marina dan dampak akumulasi logam berat timbal (Pb) dengan melihat gambaran histologi A. marina pada beberapa organ tanaman di perairan muara sungai Kebon Agung, kecamatan Gunung Anyar, kota Surabaya yang tercemar dan pantai Bama, Taman Nasional Baluran, kabupaten Situbondo yang relatif bersih. Akumulasi logam berat Timbal (Pb) pada sedimen tertinggi terdapat di perairan muara sungai Kebon Agung yaitu sebesar 13,157 ppm, sedangkan akumulasi Pb pada jaringan Avicennia marina tertinggi terdapat pada bagian batang dibandingkan akar, daun dan buah, yaitu sebesar 5,890 ppm. Dari hasil pengamatan histologi menunjukkan bahwa tidak terdapat kerusakan pada jaringan akar dan batang, namun adanya blok hitam pada jaringan epidermis atas daun dan terjadi deformasi jaringan xilem dan floem pada buah. Kata Kunci :  Timbal (Pb), Avicennia marina, histologi.

Abstract

The flow water velocity is closely correlated to oxygen  demand. Oxygen plays an important role as the indicator of fish blood. The objective of research is to acknowledge red blood cell, hematocrit, hemoglobin, and white blood cell of grouper larvae given with flow water velocity treatments.  Research begans from June 2011 to September 2011 at Lampung Marine Aquaculture Center. Juvenile with 7-9 cm length and 15-17 g/fish weight were tested using complete random design with three treatments of flow water  velocity, i.e. 1.25 m/sec (A), 1.00 m/sec (B), and 0.75 m/sec and control treatment. All treatments had 3 replications. Result of research indicates that flow water velocity had obvious effect on red blood cell, hematocrit, hemoglobin, and white blood cell. Red blood cell total was the highest in treatment of 1.25 m/second, counted for 2,922,666 cells/ml. It was  followed by treatment B with 2,816,000 cell/ml, treatment C with 2,763,000 cell/ml and control with 2,573,333 cell/ml.  The highest hemoglobin was found in treatment A, followed by B, C, and control treatments. The highest hematocrit rate was seen in treatment A, followed by B, C and control treatments. The highest white blood cell total was discovered in control, followed by C, B and A treatments.
