Abstract

A study on the community of butterfly fish (Chaetodontidae) has been conducted from April to June 2013 in two locations of coral reefs at Taman Nirwana coastal area, Padang, namely tourism zone and mangrove zone. This study aimed to determine composition and community structure of butterfly fish. This study used visual census method with limitation of 2.5 meters of view to the left and to the right along the line transects. The results found that nine species of butterfly fish which belong to two genera; Heniochus and Chaetodon. There were three species of Heniochus (i.e Heniochus pleurotaenia, H. varius, and H. Singularis) and six species of Chaetodon (i.e Chaetodon triangulum, C. collare, C. vagabundus, C. trifasciatus, C. rafflesii, and C. Kleinii). The abundance and species diversity of butterfly fish did not significantly differed between tourism and mangrove zones. In line with the two previous parameters, similarity indices were found very close between the tourism and mangrove zones. The low index values for all of the parameters may indicate a low quality of the coastal area community due to the human interferences.Key word : Chaetodontidae, composition, community structure, Nirwana Park beach-Padang

Abstract

The industrial liquid waste of crude palm oil contains organic material that can lead to degradation of water quality and ultimately affect the macrozoobenthos communities living on the river bed. The Masang Kecil River in Kinali Pasaman Barat receives the liquid waste of the palm oil industry. The research aimed to find out the composition and structure of macrozoobentos community in  Masang Kecil River and determine the water quality of river based on macrozoobenthic community structure was done in June 2017. The research was conducted by survey method with purposive sampling technique. Samples were collected on 3 stations: Station I before entering the liquid waste of palm oil industry, Station II after entering the waste, Station III is located after Station II which has been entered by Anak Aia stream. In each station collected three samples of macrozoobentos with a surber net size of 30x30 cm2. The results showed that macrozoobenthos community found 43 species consist of 33 species of Insecta, Oligochaeta 4 species, Gastropoda 3 species, Hirudinae 2 species, Arachnida and Turbellaria one species respectively. The largest number of individuals was shown by Insecta (71.89%) followed by Hirudinea (25.1%) and the other class was not more than 3%. The highest density is found at station III and the lowest at station I. The dominant species on station I were Stenelmis sp. and Psephenoides sp., stations II and III were Erphobdella sp. and Hydropsyche elisoma. The diversity index ranges from 1.49 to 3.01. The index of equitability ranges from 0.47 to 0.89, the dominant index ranges from 0.06 to 0.43. The similarity of communities between station ranged from 38.46 - 55.0%. Based on the index of diversity, water quality in Station I was classified as not polluted, Station II and III classified as moderate.

Abstract

Pintu Ngalau cave is flowed by river from irrigated rice fields that flows into the cave. This cave has a source of organic matter derived from bats and swallow dirts, litter that falls on enterance of the cave and the organic material carried by the flow of the river. The study on the macrozoobenthos communities of river in Pintu Ngalau Cave has been conducted from October until November 2016. The study used survey method, where stratified random sampling was applied in three zones (light zone, dim zone and dark zone) at study site. Macrozoobenthos samples was collected by surber net. This study also measured the physic-chemical of water. The results showed the composition of macrozoobenthos in the Pintu Ngalau cave river consisted of 43 genera i.e Gastropods (2 genera), Hirudinea (2 genera), Insects (36 genera) and Oligochaetas (3 genera). Total density of macrozoobenthos in this site was 2100 ind/m2 and the highest density was found in dark zone. The highest total relative density (KR total=79,89%) on genus level at every zone was Hydropsyche. Diversity index of macrozoobenthos was classified as medium (H'=2.68) with evenness distribution was evenly (E=0.61) and no dominant genus (C=0.14). The existence of macrozoobenthos was not influenced by light intensity, but instead was more influence by the condition of the substrate and the flow of water in the cave.

Abstract

A study on composition and structure of phytoplankton community at Maninjau lake was conducted from April to July 2013. The planktons were sampled purposively at 11 stastions using vertically towed of plankton net. This study found a total 94 species of phytoplankton that mostly belong to Chlorophyceae. Density of phytoplankton varied significantly between sampling stations ranged from 1,083 to 5,119 ind/l. The highest density was found at Station where agriculture plant dominated the vegetations around the edge of the lake, while the lowest density found at station located near the centre of the lake. Those phytoplanktons with relative density higher than 5% were Synedra ulna, Cosmarium compressus, Cosmarium decoratum, Sturastrum playfairi, Chroococcus disperses, Chroococcus limneticus and Glenodinium quadridens. Diversity indiches of phytoplankton (H`) was ranged from 1,96-2,80 with highest diversity at Galapuang (near garbages disposal area and fish farms) and the lowest was at Pakan Rabaa (water inlet). Equitability indiches (E) ranged from 0.65 to 0.81. The Index of Similarity phytoplankton was range from 28.12-70.00%. The result of this study might suggest that composition of the phytoplankton in the lake was relatively high although the structure reflected some influencees of human activities.Key word :phytoplankton, community, diversity, and Maninjau Lake.
