Abstract

ABSTRACTCorpse flower (Amorphophallus paeoniifolius) is one of the seasonal herbaceous plants including familia Araceae that can grow well in the shade. The shade of vegetation can be used as the corpse flower habitat preferences in the region, making it easier to know the population of the largest corpse flower under the shade of vegetation. This study aims to determine the type of vegetation that the shelter and to find out how the diversity index of vegetation corpse flower shade in the Padang Tiji sub-district of Pidie district. The Research was done by finding the whereabouts of the corpse flower in Padang Tiji to key persons at the altitude of 200, 400 and 600, so it can be done later retrieval corpse flower shade vegetation data using squares method. At each elevation laid five plots area of each plot was 10 m x 10 m. Based on the analysis of vegetation that houses the corpse flower, found as many as 20 species from 11 familia. Corpse flower is found in the shade of a tree Sterculia alata and Areca catechu, so that both species have the highest among other species on the third altitude. Additionally, Leea aequata and Eupatorium odoratum are also shade of vegetation that were dominant at the three altitudes for the habitus of shrubs / bushes. Thus, the corpse flower shade preferences can be known from the type of vegetation shading. Vegetation diversity index auspices of the corpse flower has a lower category either on habitus trees or shrubs / bushes.Keywords: the corpse flower, vegetation, shade, diversity index.

Abstract

Study about "Effect of Salinity on Growth and Vitamin C Content of Aloe (Aloe vera L.) on August-September 2016 in Garden of Agriculture Faculty and Biology Laboratory of Educational Faculty, Syiah Kuala University. The aim of the study is to determine the effect of salinity on growth and Vitamin C content of aloe vera. Study used a Completely Randomized Design (CRD) with the provision of NaCl treatment with different concentrations are: P0 = 0 mM, 150 mM = P1, P2 = 200 mM, 250 mM P3. Parameters that were measured are plant height, leaf number, leaf length, leaf thickness and content of vitamin C in the stem of aloe vera. Data were analyzed by analysis of variance (ANOVA). Further test used in plant height, leaf length and leaf thickness was LSD (Least Significance Difference ) and a further test used in the amount of leaves and content of vitamin C are a test of Duncan. The results showed that there is a real effect (F-count ≥ F 0.05) on the growth of aloe vera on the parameters plant height, leaf number, leaf length, leaf thickness and content of vitamin C. It is concluded that treatment of different salinity give negatively effect for growth, but positively effect on vitamin C content.Keywords: Growth, salinity, Vitamin C, Aloe vera L.

Abstract

Kawista is one of plant that is used as traditional medicine. One of the utilization of kawista is the consumtion of this unripe fruit to cure diarrhea. Etanolic extract of this fruit contains phytochemical components that has antibacterial activity. Study about Phytochemical Screening and Antibacterial Test of Ethanolic Extract of Kawista from Aceh Besar against Escherichia coli has been conducted on June 27 until July 14, 2016. The aims of the study is to determine phytochemical contents of ethanolic extract of fruit pulp of kawista and the effect of various concentrations against the growth of E. coli. Kawista which is used in the study gained from Aceh Besar. Phytochemical test showed that ethanolic extract of fruit pulp of kawista contain various active compounds such as alkaloids, saponins, tannins, triterpenoids, and polyphenols. E. coli that is used in this study were obtained from Microbiology Laboratory of Veterinary Faculty, Syiah Kuala University. The method used in the study is laboratory experiment using a quantitative type of Completely Randomized Design (CRD), which are divided into 7 groups, 5 treatment groups (ethanolic extract of fruit pulp of kawista) and 2 control groups using aquades (negative control) and streptomycin (positive control). Data analysis was performed by using ANOVA (Analysis of Variance) and then proceed with the test of HSD (Honestly Significant Difference) at α 5%. Antibacterial test results showed ethanolic extract of fruit pulp of kawista could inhibit the growth of E. coli (317.5 2.85). The highest inhibitory zone obtained at 500.000 ppm, with an average diameter of 16.141 mm. Conclusion of the study is showing that the extract of kawista pulps has antibacterial activity against E. coli bacterial growth. The higher concentration of the extract, the greater antibacterial activity against E. coli bacterial growth. Keywords: Ethanolic extract of kawista, antibacterial, Escherichia coli.
