Abstract

Fluorescent pseudomonads are a group of plant rhizosphere bacteria capable of producing antimicrobial compounds in the form of siderophores, HCN, decomposing phosphates and producing growth hormone Indole Acetic Acid (IAA). Fluorescent pseudomonads have various potentials as agents for controlling disease and increasing plant growth. Therefore, to maximize the potential of fluorescent pseudomonads, it is necessary to test compatible with each other. The aim of this study was to obtain compatible fluorescent pseudomonad isolates. This research is a descriptive study that informs the compatibility of fluorescent pseudomonad isolates isolated from plant rhizosphere. Compatibility test was carried out between the isolated fluorescent pseudomonad isolates. The results of this study obtained 6 combinations of compatible isolates: Pf1 x Pf8; Pf1 x Pf10; Pf7 x Pf9; Pf7 x Pf10; Pf8 x Pf9; and Pf9 x Pf10.

Abstract

Red chili (Capsicum annuum L.) is an important horticultural commodity in Indonesia. Red chili propagation can be done by seed. Giving biological agents to seeds can accelerate the germination process. One of the biological agents capable of accelerating germination is fluorescent pseudomonad. Several species of pseudomonads are biological agents that can produce Indole Acetic Acid (IAA). This hormone plays a role in accelerating plant growth and development. The aim of this study was to examine the effect of fluorescent pseudomonads producing Indole Acetic Acid (IAA) on the germination of red chili (Capsicum annuum L.). This research is descriptive research and experimentation. The study design used was a complete randomized design (CRD) with 6 treatments (pf1, pf5, pf8, pf9 and pf10 isolates, and a aquades) and 3 repeats. The results showed that all the fluorescent pseudomonad isolates were able to produce IAA. The application of fluorescent pseudomonads did not significantly differ on germination, but significantly different on root length and stem length.

Abstract

Fluorescent pseudomonads are a group of bacteria derived from plant rhizosphere and have the ability to produce antimicrobial compounds, namely cyanide acid. This study aims to obtain fluorescent pseudomonad isolates that can produce cyanide acid. The fluorescent pseudomonad isolates used were isolate Pf31 (derived from the rhizosphere of the longan plant), Pf32 (derived from the rhizosphere of the cassava plant), Pf33 (derived from the rhizosphere of the guava plant), Pf35 (derived from the rhizosphere of the galangal plant), Pf36 (derived from the rhizosphere of the guava plant). red ginger), Pf37 (derived from the rhizosphere of the Alocasia plant), Pf38 (derived from the rhizosphere of the celery plant), Pf39 (derived from the rhizosphere of the turmeric plant), and Pf40 (derived from the rhizosphere of the Oxalis plant). This research is a descriptive study conducted by detecting the ability of fluorescent pseudomonads to produce cyanide. The results of this study showed that 4 isolates produced cyanide, namely Pf31, Pf37, Pf38, and Pf39. Pf31 and Pf37 isolates produced the highest cyanide acid, indicated by a brick red color on the filter paper and Pf 32, Pf33, Pf35, Pf 36 and Pf40 isolates did not produce cyanide acid with the filter paper remaining yellow.

Abstract

Hemoglobin functions to carry oxygen and circulate throughout body. Several factors affect levels hemoglobin, one of which is food, foods high in cholesterol cause disruption of the quality hemoglobin, this can be overcome by giving Salacca vinegar on a reagular basis to mice that have cholesterol. This study aims to determine the effect of giving Salacca vinegar on Hb levels given high-cholesterol diet. The design used was completely randomized design with 5 treatments (K-: without high-cholesterol diet and SV (Salacca vinegar), K+: given high-cholesterol diet without being given SV, P1: SV 0.8ml, P2: SV 0.4ml and P3 : SV 0.2 ml) with 5 replications. Parameters observed were the Hb levels of male mice before and after being given Salacca vinegar. Data were analyzed using ANOVA, followed by further test of BNT with level of 5%. Results this study indicate that administration Salacca vinegar for 14 days can affect increase in the Hb levels of male mice. The treatment that showed a significant effect was the P3 treatment (SV 0.2ml) because it could increase Hb levels to 17.90 g/dL. Increase Hb levels was due to effect of flavonoids in Salacca vinegar, flavonoids keep haeme ion stable and facilitate production of methemoglobin.

Abstract

Sumatra has a variety of habitats ranging from lowlands with swamps and peatlands to highlands such as tropical rain forests, so that the organisms in it are diverse. However, the actual level of biodiversity is still not well documented. This is due to the weakness and lack of comprehensive field survey efforts. One group of animals that has received less attention is the anura group. Anura surveys have been widely carried out on the island of Sumatra, starting around 50-60 years ago, but the surveys conducted have not been broad or comprehensive, inconsistent or only done sporadically. This study aims to determine the types of anura found in watersheds in the Anai Valley Nature Reserve, Tanah Datar Regency, West Sumatra. Data collection was carried out using the path transect method along the river flow and carried out at night. Found 7 species of anura consisting of 5 families. The value of species richness in the Anai Valley CA watershed is relatively low, namely 1.5855; the value of medium species diversity is 1.4376; and the dominant value is 0.3197.

Abstract

The types of anura that are very widely distributed are predicted to consist of several species, such as the Hylarana erythraea species. Although common and widespread, research to reveal the character of this type of call sound has not been carried out. This study aims to analyze the character of the voice called H. erythraea from the Padang State University campus area. A total of 27 calls were successfully recorded and then analyzed using RavenPro 1.6.1 software. The results show that H. erythraea has two types of calls. Type 1 consists of two notes, while type two only consists of one note. Call frequency in both types is not modulated. The average call duration for type one is 0.45 seconds, while for type two is 0.056 seconds. The average dominant frequency of type one calls is 1894.92 Hz and type two is 1860.47 Hz. The average call interval is 5.16 seconds. The mean dominant frequency or call duration of the West Sumatran sample differs from that of the Singaporean and Thai populations. Further confirmation using more comprehensive evidence is expected to confirm the taxonomic status of H. erythraea of the entire distribution area.

Abstract

The habit of eating fast food can cause various diseases in the body due to the presence of preservatives in these foods. By consuming foods that contain lots of purines and alcohol will increase the content of uric acid (gout) in the blood as the main cause of gout. Uric acid (gout) is produced by the body so that its normal presence in the blood, then (gout) or uric acid is formed as a waste of protein metabolism in foods containing purines. The purpose of this study was to determine the effect of salacca vinegar on uric acid levels in male mice (Mus musculus L.). This research is an experimental research. The research was conducted from August to October 2021 at the Zoology Laboratory, Department of Biology, FMIPA, Padang State University. The method or design used was Completely Randomized Design (CRD) with 5 treatments and 5 replications for each group. The data obtained were analyzed for variance or analysis of variance (ANOVA). The results of this study showed that a dose of 0.8 ml of salacca vinegar in treatment 1 (P1) gave the best results in reducing uric acid levels in male mice (Mus musculus L.). Based on the research that has been done, it can be concluded that the treatment of giving salak vinegar has an effect on reducing uric acid levels in male mice (Mus musculus L.).

Abstract

The main conclusion contains what is the implication to other studies or to the future brought by the study. Xylanase is an enzyme that is widely used in industry because this enzyme can hydrolyze xylan (hemicellulose) into xylo-oligosaccharides and xylose. This enzyme can be produced by thermophilic bacteria. One of the benefits of xylanase is as an environmentally friendly fabric bleaching process (biobleaching). The use of xylanase enzymes can reduce the use of toxic chemicals such as chlorine by about 20-40%. The purpose of this study was to determine the effect of temperature and pH on xylanase production activity using rice straw xylan extract as a substrate and to see the potential of MS 18 thermophilic bacterial xylanase on fabric brightness. This research is a descriptive study with temperature and pH optimization treatment using 6 treatments and 3 replications, respectively. Enzyme activity was measured using a spectrophotometer with a wavelength of 540 nm. The data obtained are displayed in the form of tables and figures. The xylanase potential on the brightness level of the fabric was seen based on the results of the kappa number. The results of this study obtained the optimum temperature of xylanase activity at a temperature of 50℃ with the highest xylanase 3.792 U/mL. while at pH the optimum pH of xylanase activity was found at pH 7 with the highest xylanase production of 4.448 U/mL. The potential of xylanase on the brightness of the fabric based on the results of the kappa number is 2.04 lower than without using xylanase, which is 6.46.

Abstract

Indonesia is a mega-biodiversity country, one of the most abundant biodiversity is fungi or mushrooms. Fungi or fungi are generally classified into two types, namely microscopic fungi and macroscopic fungi. Mangrove forests are ideal habitats for fungi because of the characteristics of the area which is always moist. This study aims to determine the types of macroscopic fungi in the Karan Sungai Pisang Mangrove Forest, Teluk Kabung District, Padang City, Sumatra. This study used a random roaming method in the mangrove forest area and the technique of collecting samples was incidental. The results obtained 9 types of mushrooms, namely: Irpex lacteus, Auricularia auricular, Myxarium sp., Lentinus sajor caju, Trametes sp. 1, Trametes sp. 2, Rigidoporus sp., Ganoderma lucidum, and Daldinia concentrica. These mushrooms belong to 6 families, namely: Phanerochaetaceae, Auriculariaceae, Hyaloriaceae Poliporaceae, Ganodermaceae, and Xylariaceae.
