Abstract

Logam berat merupakan unsur logam yang berbahaya dan dapat menimbulkan pencemaran. Salah satu logam berat yang berbahaya yaitu kadmium (Cd). Pencemaran logam berat dalam perairan dapat diatasi dengan menggunakan tumbuhan air. Kayu Apu (Pistia stratiotes L.) merupakan tumbuhan air yang efektif menyerap dan menurunkan berbagai logam berat seperti Hg, Cd, Mn, Ag, Pb, Zn. Sehingga perlu dilakukan penelitian untuk mengetahui dampak berbagai konsentrasi Cd terhadap morfologi dan anatomi akar Pistia stratiotes L. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 1 faktor yaitu konsentrasi Cd (0 ppm, 4 ppm, 8 ppm, dan 12 ppm). Masing-masing perlakuan dilakukan pengulangan 3 kali. Perlakuan dilaksanakan selama 14 hari dengan parameter morfologi dan anatomi akar (jumlah trakea akar). Hasil penelitian menunjukkan bahwa secara morfologi, akar tumbuhan yang terpapar logam Cd mempunyai tekstur akar yang lunak dan rambut akar sebagian besar terputus. Secara anatomi, menunjukkan perbedaan yang nyata tiap perlakuan terhadap jumlah trakea akar. Dimana semakin tinggi logam Cd maka jumlah trakea semakin sedikit. Adanya perbedaan jumlah trakea tersebut berkaitan dengan kerja enzim dan hormon pada pembentukan sel-sel trakea akar Pistia stratiotes L. Kata Kunci : Morfologi, Anatomi, Akar, Pistia stratiotes L. logam Cd

Abstract

The study aimed to know the effect of different salinity on shrimp of protein content and protein profiles. The animal in this study was Macrobranchium sintangense shrimp with average length ± 50 mm which has acclimation for three days. The shrimp was treated at different salinity, the salinity 0 0/00, 5 0/00, 100/00,15 0/00 and 20 0/00 for seven days. Protein content and protein profiles by taking shrimp gill. Shrimp gill test showed that has a different protein content, protein profiles due to treatment of different salinity. The result was conclude that salinity 0 0/00, 5 0/00, 100/00,15 0/00 and 20 0/00 affect protein content and protein profiles of M. sintangense.

Abstract

Air pollution is changes of air arrangement from its normal state that is caused by the ingress of foreign materials or substances in the air. The resulting pollutants include SO2, NO2, CO2, O3, hydrocarbons, and heavy metals such as lead (Pb), zinc (Zn) and cadmium (Cd). The impact of plant’s vehicle exhaust gas is seen from the leaf mesophyll damage especially in the palisade tissue and the reduced number of stomata. Responding to the problem, conducted research with the aim to know the influence of pollution on the amount of stomata on the plant bamboo rejeki (Dracaena reflexa) as ornamental plants absorb pollution in the area of Malang city using the method of polishing the acne (aceton). The results showed that the number of stomata in polluted areas of vehicle pollution decreased at each point compared to areas not polluted by vehicles. In the contaminated area the average number of stomata is at point one 49, the second point 42.5, and the third point 37, whereas in the area that is not contaminated with the average number of stomata at point one 60.5, the second point is 68, and the point three is 70,5. Damage or Decrease in the number of stomata occurs due to the entry of gas that is toxic through stomata with diffusion process, so that the liquid composition of the cell becomes disturbed and the cell becomes damaged and dead.
