Keragaman Jenis Plankton di Perairan Laut Kota Jayapura, Papua Suharno Suharno; Daniel Lantang
Jurnal Biologi Papua Vol 2, No 1 (2010)
Publisher : Jurusan Biologi FMIPA Universitas Cenderawasih

Dalam penentuan kesuburan suatu perairan, plankton mempunyai peranan penting. Hal ini disebabkan karena plankton merupakan produsen yang mampu melakukan fotosintesis. Plankton mempunyai peranan penting dalam sistem rantai makanan di kawasan perairan, baik di laut, perairan air tawar maupun payau. Sehubungan dengan hal tersebut telah dilakukan penelitian tentang keragaman jenis plankton di perairan laut di Kota Jayapura. Metode yang digunakan adalah survey, dengan pengambilan sampel pada tiga (3) lokasi yang berbeda, yakni di Pantai Dok II, Pantai Hamadi, dan Pantai Skow Mabo. Hasil penelitian menunjukkan bahwa di Kota Jayapura, khususnya di stasiun penelitian Pantai Dok II, Pantai Hamadi, dan Pantai Skow dijumpai 52 jenis plankton. Dari 52 jenis tersebut satu (1) diantaranya belum dapat teridentifikasi, yakni dari jenis fitoplankton. Di Pantai Dok II, dijumpai 25 jenis, pantai Hamadi terbanyak yakni 32 jenis, dan Pantai Skow hanya 16 jenis. Jenis–jenis plankton di lokasi ini menunjukkan tingkat kesuburan perairan pantai. Pantai Hamadi tergolong jenisnya sangat beragam, sedangkan pantai Skow tidak mempunyai keragaman yang tinggi.Key words: Keragaman plankton, Pantai Dok II, Pantai Hamadi, Pantai Skow, Jayapura.

The growth of a plant is influenced by the availability of nutrients. To meet these nutritional needs, chemical fertilizers are still widely used. In addition to nutritional needs, the growth of a plant is also influenced by pathogenic microorganisms that cause disease. The emergence of diseases in plants causes chemical pesticides to be increasingly used. The continuous use of chemical fertilizers and chemical pesticides can make living organisms susceptible to high toxicity of chemical compounds. In addition, the impact has an impact on improper management of agricultural waste as well as polluting the environment when it has been burned or discharged into water bodies. One alternative to overcome these problems is the application of biological control using Trichoderma spp. Trichoderma spp inoculum application can significantly regulate the rate of plant growth and suppress the growth of plant pathogenic microorganisms. Trichoderma spp. including plant growth promoting microbes that have the ability to colonize plant roots so as to provide benefits to their host, modulate phytohormonal production, increase soil nutrient availability, stimulate plant growth and tolerance to biotic and abiotic stresses, and resistance to pathogens. Inoculum of Trichoderma spp. can be applied to plants through seeds, leaves, roots of seedlings, and soil. Based on literature review, it is known that the application of Trichoderma spp. inoculum showed a significant effect on plant growth and suppress the growth of pathogenic microorganisms.Key words: Trichoderma spp.; inoculum; fungi; biofertilizer; biofungicide.

The increasing industrial activity in Indonesia, that is not equipped with appropriate waste treatment, has caused an increase of heavy metal contaminants in water bodies. Heavy metals contamination such as copper (Cu), mercury (Hg), cadmium (Cd), and lead (Pb) contamination in water bodies have endangered aquatic life and public health. For this reason, it is urgently important to lower down the concentration of heavy metal pollutants in the water bodies surrounding industrial areas. Compared to chemical remediation, bioremediation of heavy metal by using indigenous bacteria is more effective and economical, since it can be applied in situ directly and be used repeatedly. Acinetobacter sp. IrC2, used in this study, is Indonesian indigenous bacteria isolated from the industrial waste treatment facility in Rungkut, Surabaya. This study aims, firstly, to investigate the heavy metal multiresistance of Acinetobacter sp. IrC2 against mercury, cadmium, and lead. Secondly, this study intends to examine its bioaccumulation capacity for single and heavy metal alloys. The heavy metal multiresistance test was carried out by measuring the minimum heavy metal concentrations that inhibit bacterial growth (Minimum Inhibitory Concentration/MIC). The bioaccumulation capacity was measured using an atomic absorption spectrophotometer (AAS). It is shown that Acinetobacter sp. IrC2 has high multiresistance to mercury, cadmium, and lead with MIC values of 12 mM, 8 mM, and 18 mM, respectively. Furthermore, it is also resistant to heavy metal mixture of 4.5 mM. The mechanism of bacterial resistance in response to heavy metal toxicity, in general, is by accumulating heavy metals in the cells. The highest amount of accumulated heavy metals identified, from bacteria grown in the medium contains a mixture of heavy metals, were 0.023 mg, 0.084 mg, 0.684 mg, and 1.476 mg per gram of cell dry weight for copper, mercury, cadmium and lead respectively. In conclusion, Acinetobacter sp. IrC2 is a promising heavy metal bioremediation agent due to its heavy metal multiresistance and accumulator characteristics. Key words: Acinetobacter sp. IrC2; cadmium; copper; lead; merkuri
