Abstract

The study about population density and size distribution of clam (Rectidens sp.) at Tanjung Mutiara Singkarak Lake, West Sumatra has been conducted from June to July 2013. The clams were collected using stratified purposive sampling method. Sampling site was decided into three location based on human activities and three depth strata in each location (<5m, 5-10m and >10-15m). The clams were collected using “dauah” (traditional tool to cath shellfish). There were 43 individu of clams that found at Tanjung Mutiara Singkarak Lake. The highest average population density were found at location III (1.444 ind./m2). The highest average population density were found at strata 3 (1.082 ind./m2). Size distribution of clam showed that at each location and strata have different size. The size of the clam between 24.37-88.54 mm. Medium size clam were the most frequent found in comparison with the small size and large clam. Small clam distributed at strata 2 (5-10 m) locations I and III and strata 3 (> 10-15 m) location III. While large clam only distributed at strata 3 (> 10-15 m) locations II and III. Size distribution of clam varied with the type of substrate and substrate particle.Keywords: clam, Rectidens sp., population density, size distribution

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

Generally the essential oils are antibacterial and antifungal. Cymbopogon nardus which is included in Graminae family commonly produced an essential oil. Another plant Elettariopsis slahmong which is known contains essential oils derived from Zingiberaceae family has not been commonly used. This plant is only used as a spice and salads in Malaysia, Thailand and Indonesia. A study about antifungal activity of essential oil of citronella grass (Cymbopogon nardus L.) and elettariopsis slahmong Lim. against Colletotrichum sp. on Red Dragon Fruit (Hylocereus polyrhizus) was conducted since March to May 2013 in the Laboratory of Microbiology, Department of Biology, Andalas University. This study used experimental method with three dose treatments and three replications for each kind of essential oils. The essential oils were distillated from Cymbopogon nardus and Elettariopsis slahmong. The treatments used 250, 500 and 750 ppm of essential oils. This study found that Cymbopogon nardus could be a potential antifungal prevent Colletotrichum sp. The higher dose was the better preventive effect. There was no effect of Elettariopsis slahmong on Colletotrichum sp.Keywords: essential oil, Cymbopogon nardus, Elettariopsis slahmong, antifungal
