| dc.description.abstract | A study aims to understand the types of Epiphytic periphyton that are attached in the leaf of Pandanus sp. has been conducted August-September 2012. The taking Epiphytic periphyton samples and water quality parameters measurement conducted simultaneously 3 times with intervals of 1 week, which is 1 time per week at 3 stasions. Epiphytic periphyton samples obtained by scraping a toothbrush and spraying the leaves of Pandanus sp. stem surface 2 (3 x 15 (cm)) with aquadest using a plastic sprayer. The Epiphytic periphyton were preserved using Lugol 1% and identified based on Davis (1955) and Prescott (1970). There were 37 species of Epiphytic periphyton consisting of 4 classes, namely Bacillariophyceae (22 species), Chlorophyceae (13 species), Chrysophyceae (1 species) and Xantophyceae (1 species). Epiphytic periphyton abundance 266-868 (sel/cm2), diversity index (H’): 1.380-2.526, uniformity index (E) : 0.628-0.962, dominance index (C): 0.089-0.382. Results of water quality measurements are as follows: temperature: 29- 31 (oC); clarity: 34-37 (cm); depths: 4-7 (m); flow velocities: 0.08-0,15 (m/sec); the pH 5-7; DO: 7,16-7.34 (mg/l), carbondioxide-free: 6,99-7,39 (mg/l), nitrate: 0.03-0.04 (mg/l); phosphate: 0.005-0.007 (mg/l). Based on data obtained, it can be concluded that the waters quality in the Segati River is criteria lightly contaminated and low fertility but able to support the life of Epiphytic periphyton and Pandanus sp..
