Abstract

Research on The Presence of Natural Microflora in Fermentation of Green Apples Cider Vinegar (Malus sylvestris Mill.) Cultivars Granny Smith was conducted from February to June 2014 at Microbiology Research Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Andalas University, Padang. The purpose of the research were to determine the Presence of the natural microflora (yeasts and bacteria) in fermentation of a Granny Smith apple cider vinegar and to determine the character of apple cider vinegar in terms of pH value dan sugar content. The results showed that the fermentation of apple cider vinegar was the Presence of the natural microflora (yeast as much as 1.8 x 106 cfu/ml and bacteria as much as 3.4 x 106 cfu/ml) and obtained with apple cider vinegar acid concentration (pH 3.13) with a residual sugar content (1.5% Brix) after 14 days of acetic acid fermentation.Keywords:       Natural Microflora, Granny Smith Apples, Apple Cider Vinegar

Abstract

A study about dung beetles species was conducted at the Educational and Biological Research Forest. Pitfall trap method was used to collect dung beetles which cow, cat and human feses were put above each of the trap. The beetles colection was conducted at four locations (river, permanent plot, camp and villa). A total of 10 species of dung beetles that belong to two subfamilies, three tribes and five genera was collected. About three species were not reported in previous studies in West Sumatra.Keywords: Coleoptera, Scarabaeidae, Pitfall trap, West Sumatera

Abstract

Artemesia vulgaris L produce artemisinin which is effective against resistant strains of Plasmodium falciparum, the malarial parasite. The study about growth responses of Artemesia vulgaris L in Murashige-Skoog (MS) medium supplemented with several growth regulators had been done from September to November 2014 at the Laboratory of Plant Phisiology and Tissue Culture, Department of Biology, Faculty of Mathematic and Natural Science, Andalas University. The aims of the study was to know the responses of node explants of Artemesia vulgaris L supplemented with several plant growth regulators for the effective technique of propagation. The study used Completely Randomized Design with four treatments and six replications. Node from in vitro growth were treated with three different kind of growth regulator (0.3 ppm BAP, 0.5 ppm NAA, 0.3 ppm GA3) in MS medium. The result showed that 0.5 ppm NAA was the best growth regulators formed callus, bud, and root of Artemesia vulgaris L.Keywords: Artemesia vulgaris L, plant growths regulator, in vitro

Abstract

Hornstedtia leonurus is one species of the Hornstedtia’s genera in Alpiniae Tribe (Zingiberaceae). It has unambiguous expressed some aberrations of morphological characters in what Hornstedtia should have. On the contrary, it has with it self some characters from other genera within the tribe of Alpiniae, such as Etlingera and Amomum. The research aimed to find some distorsion on morphological characters of the H. leonurus with its close selected sisters in Alpiniae Tribe (Etlingera megalocheilos and Amomum cardamomum) and determined their were characters relationship by a morphometric study. The materials collected from West Sumatra province (50 Kota, Padang and Sijunjung regency) on September until December 2015. Morphometric analysis used PAST version 2.17c and SPSS computer programs. Morphologically, H. leonurus closely related with E. megalocheilos rather than its sister in Hornstedtia genera (H. schypifera) and A. cardamomum.Keywords: Alpiniae, H. leonurus, morphometric, relationship, Zingiberaceae.

Abstract

Anatomical structure characterization of some wood genus of Sapindaceae in West Sumatra was conducted from May to October 2015 with survey and direct observation method. Cluster analysis conducted using PAST program to determine relationship among genus investigate on present study. The woods of nine genus namely Filicium, Nephelium, Pometia, Guioa, Xerospermum, Sapindus, Harpullia, Lepisanthes and Mischocarpus were analyzed. All of i.e, character vessels, parenchyma, rays and fibre morphology were analyzed by using permanent slide based on Sass (1958) procedured. The results showed all of woods have same type of porous namely diffuse porous. Type of vessel distribution namely soliter in Xerospermum and multiple in Filicium, Nephelium, Pometia, Guioa, Sapindus, Harpullia, Lepisanthes and Mischocarpus. Xylem parenchym type namely apotracheal in Pometia and Lepisanthes and paratracheal in Filicium, Nephelium, Guioa, Xerospermum, Sapindus, Harpullia and Mischocarpus. Rays type namely uniseriate type in Nephelium, Pometia, Sapindus, Harpullia and Lepisanthes and multiseriate type in Filicium, Guioa, Xerospermum and Mischocarpus. Rays composition namely heterocellular in Filicium, Sapindus, Harpullia and Nephelium and homocellular in Mischocarpus, Lepisanthes, Pometia, Xerospermum and Guioa. Fiber size is long chategory in Nephelium genus, medium in Filicium, Xerospermum, Harpullia and Lepisanthes, and short chategory in Pometia, Sapindus, Guioa, and Mischocarpus. Cluster analysis showed up among genus present of two cluster namely uniseriate rays cluster and multiseriate rays cluster. Both the cluster genus member showed clustering tightly except Nephelium genus weakly clustering in the multiseriate cluster do to have different fiber size chategory from the other genus. The character of woods using at present study useful as additional character of morphologically data to determine of genus taxa.Keywords : anatomical structure, family Sapindaceae,  permanent slide, relationship

Abstract

The research on effect of types and concentration of auxin on root induction of apical shoots Bayur (Pterospermum javanicum jungh.) in attempt to propagate of revegetation plants was conducted from May to August 2015 in the Nursery and Greening of Andalas University, and Laboratory of Plant Physiology Department of Biology, Faculty of Mathematics and Natural Sciences, Andalas University. The aimed to know the response of apical shoots Bayur (P. javanicum) on  root induction by providing some type and concentration of Auxin. This research used method of Complete Randomized Design (CRD) with seven treatments and three replications. The treatments consist of control, IBA 100 ppm, IBA 200 ppm, NAA 100 ppm, NAA 200 ppm, IAA 100 ppm, IAA 200 ppm. The result of this study showed that there was no respons of any treatments in inducing root of  apical shoots of Bayur (P. javanicum).Keywords: Auxin, Pterospermum javanicum, revegetation, root induction

Abstract

The research related to Isolation of the Hydrocarbon Degrading Bacteria in the Contaminated Soil of the Automotive Workshop was conducted from May to October 2014 at Laboratory of Microbiology, Biology Department, Faculty of Mathematics and Natural Sciences, Andalas University. The aimed of this study was to find  the bacteria able to degradate the hydrocarbon from the lubricating oil contaminated soil and to descripe characterization of isolates. This study used a survey method in isolation and characterization of hydrocarbon degrading bacteria.  The result obtained that the bacteria able to degradate the hydrocarbon from the lubricating oil contaminated soil about 39.02% (1.6x105 cfu/g). Five isolates were found (BTTO1, BTTO2, BTTO3, BTTO4 and BTTO5) has a rod shaped, Gram-negative, motile and positive catalase.

Abstract

Pigeon orchid is one of epiphytic wild orchids and very important species in the genus Dendrobium. Flowering phenology of this species is still unclear. The purpose of this study was to describe flowering phenology of pigeon orchid. The study was conducted in Limau Manis Padang, West Sumatera and has been done from May until October 2015. Some aspects of flowering phenology such as the phase of flowers, flowering period, rainy time and stigma receptivity were observed. The results of this research  indicated that pigeon orchid flowering was induced by dicreasing of the temperature after rain. Flowers development consist of six phases from bud phase to be wilt with a span of 14 days and sometime stigma has begun receptive before the anthesis but optimal stage of stigma receptivity pigeon orchid occurs during anthesis.Key word: Phenology, pigeon orchid, stigma reseptivity.
