Abstract

Research on Spatial Spread of Invasive Foreign Plants Clidemia hirta in Bung Hatta Forest Park, Padang, West Sumatra, has been carried out from January to June 2018. The purpose of this study was to determine the spatial distribution pattern of invasive foreign plants Clidemia hirta and analyze the influence of distance from roads and influence light intensity on the distribution of the number of individuals Clidemia hirta in the Bung Hatta Forest Park. This study uses a belt transect method with a width of 2 meters along 250 meters. Along the transect, a plot of 2x2 meters was made with 125 plots. Observations made on Clidemia hirta is to calculate the number of individuals and measure the intensity of light in each plot. The results showed that the pattern of spread of  Clidemia hirta was grouped with the Morisita Index of 2.1. The distance from the road and the intensity of light does not affect the distribution of the number of individuals with R Square values of 0.022 and 0.007, respectively.

Abstract

The research about the growth of Buffalo Grass (Paspalum conjugatum Berg.) inoculated with several doses of Arbuscular Mychorrizal Fungi (AMF) ) in Media Containing with Mercury (Hg) had been done from February to July 2014 at the greenhouse, Plant Physiology and Tissue Culture Laboratory, Biology Department, Faculty of Mathematic and Natural Science and Environmental Laboratory, Faculty of Engineering, Andalas University. The aims of the research to know ability of P. conjugatum inoculated with several doses AMF in media containing with mercury and find the best dose of AMF for growh of P. conjugatum. The research used a Completely Randomized Design with five treatments and five replications. The treatments were control 0, 5, 10, 15, 20 g  AMF. The result showed that no effect inoculated of AMF up to 20 g to the height, number of leaves and dry weight of P. conjugatum.

Abstract

Bellucia pentamera is one of the most dangerous invasive alien species for environment. This species had been invaded many forests in Indonesia. This species would invade more area due to deforestation. The objectives of this study were to know the mapping and distribution pattern of B. pentamera; to know the effects of distance from road and light intensity to distribution of B. pentamera. This study was conducted from March to August 2020 in Conservation Area of PT. TKA Solok Selatan using belt transect method by plotting 20x50 m2. Data was analyzed using Morishita Index and Linear Regression. Distribution pattern of B. pentamera in PT. TKA was clumped, showed by 1.17 of Morishita index. Seedlings and saplings of B. pentamera were dominant at the edge of conservation forest while trees were distributed from the middle to inside of the forest. Distance from road gave positively effects and significantly towards distribution of B. pentamera showing result 0.702 of R2 and 0.007 of p-Value. Light intensity did not give effects significantly towards distribution of B. pentamera showing result 0.0806 of R2 and 0.427 of p-Value.

Abstract

A study about community of epilithic algae was conducted on April until August 2014. The objective of this study was to clarify composition and structure of epilithic algae in Ombilin River and water quality of Ombilin River based on community of epilithic algae. Samples were collected by survey and brushing method and the research station was choosed 6 stations purposively. The results showed that totally 72 genera had been found with total density of epilithic algae was 388.92ind/cm2to 2139.04 ind/cm2. The highest density of epilithic algae was found in station III (Talawi) and the lowest in station II (Lubuk Pinang). The dominant epilithic algae were Cocconeis, Synedra, Navicula, Denticula and Gomphonema (Baccilariophyta), Stigeoclonium (Chlorophyta), Phormidium and Calothrix (Cyanophyta), Ceratium (Dinophyta) and Audouinella (Rhodophyta). Diversity index was 1.50 to 2.48, where the highest was observed at station II (Lubuk Pinang) and the lowest one at station III (Talawi). Equitability index was 0.42 to 0.68. Similarity index was 50 to 74.70%. Saphrobic coefficient was 0.61–1. The result also showed that Ombilin Riverwere polluted slightly byorganic and inorganic materials in β-mesosaprobic phase.

Abstract

Vegetation analysis of weeds at rubber plantation (Hevea brasiliensis Mull.Arg.) at Batang Kapas, Pesisir Selatan, was carried out from March to April 2013. The weeds were sampled purposively using plot quadrat method at three and six years old of rubber plantations. There were totally 13 families, 23 genera dan 27 species of weeds found in the two types of rubber plantations. The two locations were dominated by different species of weeds. Borreria alata has the highest Summed Dominance Ratio (SDR) at three years and Scleria sumatrensis at six years old of rubber  plantations. Diversity indices were relative moderate (2,17 at three years old and 2,2 at six years old rubber plantations) in both locations and species similarity between the two location were low (45,7%).
