Abstract

The effect of mango ginger (Curcuma mangga Val.) ethanolic extract has been experimentally tested to β cell of alloxan-induced mice at the Laboratory Animal Development and Structure. The experiment aimed to identify the effectifity of the ethanolic extract to defend β cell from necrosis caused by the alloxan. The activity of the extract was evaluated by using control (A0 and A1) and treatments. All mice were induced by alloxan (150 mg/kg of body weight). One week later the extract was given orally to the mice at dose 200 (A2) 400 (A3) and 800 (A4) mg/kg of body weight (A4). The extract was given everyday for 21 days. Pancreas were isolated for each week. The observation of pancreas histology showed that extract 200 mg/kg body weight could decrease necrosis at Langerhans higher than the extract of 400 and 800 mg/kg of body weight. This results indicate that giving mango ginger extract at dose 200 mg/kg body weight could decrease β cell necrosis.Key words : mango ginger (Curcuma mangga Val.), β cell, alloxan, necrosis.

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

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.

Abstract

An experiment on the reduction of stratification period with addition of GA3 hormone to strawberry (Fragaria x annanassa (Weston) Duchesne) seeds germination has been done from December 2013 to February 2014 in the Laboratory of Plant Physiology, Department of Biology, Faculty of Sciences, Andalas University, Padang. The experiment aimed to reduce the stratification period and determine the reliable concentration of GA3 on strawberries seeds germination. The experiment was conducted by using Split Plot Design which consisted of stratification levels (0 week, 1 week and 2 weeks) as main plots, while GA3 consentration (0 ppm, 25 ppm, 50 ppm and 75 ppm) as sub plots. The results from that 25 ppm GA3 combined to 0 week showed the best acceleration to  the emergence of sprouts, increased the number of seed germinations and sprouts length but did not significantly affected to the length of time required for the germination.Key word :GA3, germination, stratification, strawberry

Abstract

The acute toxicity effects of leaf extract of dragon scales fern (Drymoglossum piloselloides (L.) Presl) on hematological values of male albino mice (Mus musculus L.) has been tested at the Laboratory Animal Physiology. The experiment tested extract dose from 50 to 200 mg/Kgbw on hematological values of male albino mice. The treatments  used a randomized block design method. The mice were injected by the leaf extract at several doses: i.e.  0 mg/Kgbw, 50 mg/Kgbw, 100 mg/Kgbw, 150 mg/Kgbw and 200 mg/ Kgbw. The blood were collected at 24 hours after treatment and hematological values have been examined including number of red and white blood cell, hematocrite, hemoglobin concentration (Hb), plasm protein concentration, absolute blood indices, diameter and morphology of eritrocyte. The results showed that the leaf extract of D. piloseloides gave no acute toxicity effect of hematological values.Keywords: Drymoglossum piloselloides, hematology, acute toxicity

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.

Abstract

Murashige-Skoog media enriched using 6-Benzyl Aminopurine (BAP) and sucrose was conducted from June 2013 to February 2014 at the Laboratory of Plant Physiology, Department of Biology, Andalas University. This study aimed to determine the ability of shoot formation of white turmeric (Curcuma zedaoria Roscoe) on the effect of BAP and sucrose concentration. We used a Completely Randomized Design (CRD) with 8 treatments and 3 replications, BAP (0, 1.5, 3 and 4.5 mg/L) and sucrose (3 and 5%) of MS medium. The result showed that the percentage of shoot induction was 100%. The best combination of sucrose and BAP in shoot induction was obtained on 5% sucrose and 1.5 mg/L BAP. While for the first immerge of shoot was obtained on 5% sucrose and 4.5 mg/L BAP in 5 days after inoculation. All treatments but did not give any significant effect to the number and height of shoots.Key words: Curcuma zedoaria, shoot, sucrose and 6-Benzyl Aminopurine
