Abstract

Periphyton is a type of algae that commonly inhabit the surface of immersed objects. A research aims to understand the periphyton community (types and abundance) in the floating-net cage in the Koto Panjang Dam has been conducted from May to June 2015. Samplings were conducted 3 times in 3 stations, namely St. I (Tanjung Alai, 50-200 cages), St. II (Pulau Gadang, 200-500 cages) and St. III (Dam Site , 500-700 cages). Periphyton samples were taken by scraping the surface of the immersed cage using tooth brush (10x10 cm2). Periphyton collected were then preserved in lugol 2-3 drop/40 ml and then was identified based on Hiroyuki (1977), Yunfang (1995), Sachlan (1982) and Bellinger and Sigee (2010).Result shown that there were 49 periphyton species present and they are belonged to 6 classes, namely Bacillariophyceae (15 species), Chlorophyceae (18 species), Chrysophyceae (1 species), Cyanophyceae (13 species), Dinophyceae (1 species) and Xanthophyceae (1 species) and the periphyton abundance was 35,945-60,690 cells/ cm2). In general, the H’ was 4.694-4.974; C was 0.038-0.052 and E was 0.890-0.917. The water quality parameters are as follows: temperature was 30-31 0C; brightness was 100.5-139.0 cm; turbidity was 1.50-2.68 FTU; pH was 5-6; DO was 5.6-6.0 mg/L; free CO2 was 3.9-4.5 mg/L; nitrate was 0.045-0.050 mg/L and phosphate was 0.035-0.041 mg/L. Based on periphyton community it can be concluded that the aquatic environment in the Koto Panjang Dam balance.Keyword : Peryphyton,Koto Panjang Dam, Kampar

Abstract

This study discussed about the reflexes of Proto Malayo-Polynesian (PMP) phonemes in Rejang language.The reflexes of Proto Malayo-Polynesian phonemes (PMP) in Rejang language covered consonants, vowels, semivowels, and diphthongs. Description of the phonemes reflexes employed a top-down reconstruction method. Based on the data analysis, it proved that reflexes of Proto Malayo-Polynesian (PMP) phonemesin Rejang language covered:(1) vowel reflexes e.g. /*e//e/, /ê/, /o/, /êa/, /oa/, /ø/; /*i//i/, /e/, /ê/, /ea/, /êy/;/*u/ /u/, /ê/, /o/, /oa/, /êw/; (2) consonant reflexes e.g. /*b//b/, /o/; /*d//t/; /*D//d/, /ø/; /*g//g/; /h//ø/;/*j//g/, /k/, /t/; /*k//k/, /?/; /*l//l/, /ø/; /*m//m/, /ø/; /*n//n/, /ñ/; /*ñ//ñ/, /n/; /*ŋ//ŋ/, /ø/; /*p//p/;/*q//?/, /ø/; /*r//r/, /ø/; /*R//l/, /?/, /ø/; /*s//s/; /*S//ø/; /*t//t/, /ø/; /*T//t/; /*z//j/, /y/; /*Z//d/, /j/;(3) semivowel reflexes e.g. /*w//b/, /w/, /a/, /ø/; /*y//y/, /e/; (4) diphthong reflexes e.g /*aw//oa/ in Rejanglanguage.
