Abstract

A research on bacteriological condition of ground well water at Air Dingin, Padang was conducted from January to March 2013 at the Health Laboratory Agency (UPTD Balai Laboratorium Kesehatan) of West Sumatra. The water samples were collected by using purposive method at three sampling points in distances of 250 m, 350 m and 450 m from garbage disposal locations. Bacteriological test was done using Most Probable Number method (MPN) with combination of 3:3:3. Escherichia coli was described using indole, methyl red, voges proskauer, citrate (IMViC test). The result showed that MPN of Escherichia coli of ground well water for each distance of 250 m, 350 m and 450 m ranges from 0 cell/100 ml to 2400 cell/100 ml. Based on bacteriological parameter test, quality of the ground well water around the landfill area was not appropriate to be consumed by people, except for ground well water was located at 450 m from landfill.Key words: ground well water, Escherichia coli, landfill, qualilty.

Abstract

Research about the affectivity of gambier (Uncaria gambir Roxb.) as anti-hypercholesterolemic and stabilizer of blood value on the male white mice (Mus musculus) have been done from August to December 2013 in the Research Laboratory of Animal Physiology, Biology Department, Mathematics and Natural Sciences Faculty, Andalas University, Padang and Sejawat Clinical Laboratory, Padang. This study aimed to determine whether gambier could inhibit the increase in total cholesterol and stabilize blood value of white mice that were given with the leftover frying oil and to determine the best dose of gambier in inhibiting the increase in total cholesterol and stabilize blood value of white mice that were given with the leftover frying oil. This study used an experimental method completely randomized design (CRD) with five treatments and five replications. Treatment with giving the leftover frying oil and gambier dose of 50; 100; 150 and 200 mg/kg and control with giving the leftover frying oil without giving gambier. The result showed that the gambier could inhibit the increase in total cholesterol and stabilize blood of white mice that were given with the leftover frying oil and the best dose is 50 mg/kg body weight.

Abstract

The study about community of macrozoobenthos at Batang Ombilin River, West Sumatra has been done from November 2012 until March 2013. This study aimed to know the composition and structure of macrozoobenthic community. This research carried out by using survey method and purposive sampling technique. Sampling site determined in six stations. In each station were collected five samples by using Surber net (30x30 cm2). The result showed that community of macrozoobenthos were found 34 species consist of Insecta 20 species, Gastropoda 5 species, Olighocaeta 4 species, Hirudinea 2 species, Lamellibranchiata, Arachnida and Turbellaria one species respectively. The highest relative density was Gastropoda (46.27 %) and the lower was Arachnida (0.28 %).  Average population was 130.18 ind/m2, and the highest density has found at Station I (391.07 ind/m2), the lower at Station V (37.77 ind/m2). Dominant species in each station were variated. Average diversity index was 1.73, the highest was found at Station V (H’=2.22) and the lowest at Station III and IV (H’=1.19).The composition of macrozoobenthos among stations  were different, with low similarity index ranged from 14.28 % - 36.36 %.Key words : Batang Ombilin, Makrozoobenthos, Composition, Structure.

Abstract

The research about the "Characterization of Natural Microflora From Cow Digestic Tract As Candidate For Cattle Feed Probiotics"  has been conducted from April to July 2013 in the Laboratory of Microbiology, Department of Biology, Faculty of Mathematics and Natural Sciences, University of Andalas, Padang. This study aimed to obtain isolates  and the character of each isolate as a candidate to cattle feed probiotics. This study used an experimental method and analyzed descriptively. The result showed that the bacteria from cow digestive tract were Cellulolytic (110x107cfu/g), Fermentative (85x107cfu/g),  Amylolytic (31x107cfu/g) and Proteolytic (28x107cfu/g) bacteria. Two of  the probiotic candidate were bacill and coccus, both of them were Gram-negative and catalase positive.

Abstract

The study about compatibility of Glomus spores isolated from the rhizosphere Macaranga triloba with three types of host plants have been done from February to November 2013 in greenhouses and Plant Physiology Laboratory, Department of Biology, Andalas University, Padang. The aim of this study was to determine compatibility of corn (Zea mays), jatropha (Jatropha curcas) and scallion (Allium fistulosum) as host plants of Glomus spores isolated from the rhizosphere Macaranga triloba. This experiment used completely randomized design (CRD) with 3 treatments and 9 replications. The treatments were corn, jatropha and scallion. The results showed that spore density of the corn and scallion gave the same effect, whereas jatropha gave different effects on the two plants. The degree of infection of corn roots and scallion showed a high criteria, while the percentage degree of infection on jatropha roots showed a moderate criteria. The corn and scallion were compatible host plants of Glomus spores isolated from the rhizosphere of Macaranga triloba.Key words: compatibility, host plants, Glomus spores

Abstract

A study on the nest characteristics of scaly-breasted munia (Lonchura punctulata) located around campus building and forest areas of Andalas University, Padang has been conducted from September 2013 to February 2014 using survey and nest sampling methods. Result of this study showed that the nest of scaly-breasted munia were located from four to six meter from the ground level. Those nest that located around the campus building were significantly higher than the forest area. Nest position in the tree of campus building area were more often found in primary branchs, whereas the nest of forest area were more often in secondary branchs. The nest of scaly-breasted munia were discover in 10 tree species. Shape and morphological size of the nest tended to be different betwen the two locations. Nest of scaly-breasted munia were made of natural materials and did not use find any synthetic material. Grass (Graminae) were the main material used for the nests.Keywords: nest, characteristics, materials, scaly-breasted munia.

This study used scan sampling and direct collection methods. Insects were identified at the Laboratory of Animal Taxonomy, Biology Department, Faculty of Sciences, Andalas University, Padang. There were totally 28 species of insects that belong to 19 genera, 10 families and three orders that actively visited the flowers. Lepidoptera was the most common insect visited the flower followed by Hymenoptera and Diptera only by one species.Keyword : insects, inventory, flower, Clerodendrum paniculatum.

Abstract

We examined the effectiveness of some insecticide aerosols to German cockroaches. This experiment was conducted at the Laboratory of Animal Physiology Department of Biology, Andalas University from July to October 2013. Animal subjects were three strains of German cockroaches, namely GFA-JKT from Jakarta, PLZ-PDG from Padang and VCRU-WHO from School of Biological Sciences, University Sains Malaysia. Those subjects were treated using spray method of five brands of commercial insecticides found in the market, namely ByWS, HtWS, MtWS, RdWS and VpWS. We analyzed  knockdown and lethal times using probit analysis. The effectiveness were evaluated based on running time to achieve the knockdown and lethal. The results showed that knockdown time (KT90) of ByWS, HtWS, MtWS, RdWS and VpWS were effective for VCRU-WHO and GFA-JKT strains and the only HtWS and RdWS were effective for PLZ-PDG strain. Based on the the lethal time (LT90)  there was no single insecticide effective to kill cockroach.Kata kunci: Blattella germanica, commercial insecticide, Spray Method, Knockdown.
