The fungus Gliocladium sp. is the microbial soil that can be isolated from the root zone of banana plant  (Musa Paradica L.) Those fungi are included in the group of potentially antagonistic microbes in the growth inhibiting of Fusarium sp fungus which infects the plants and it cause disease on banana crops withered. This research aim was to know the difference of growth inhibiting percentage of Gliocladium sp, to the Fusarium sp. fungus at pH 5.5 and pH 7. This research uses experiment methods. The results of the growth inhibiting percentage in the last day was higher at pH 5.5 of 35.2% whereas at pH 7 of 14%. This indicates that the growth of the fungus is more suitable in pH acidic approach because of its nature which is able to adjust to the fungal metabolism. The inhibition mechanism of the Gliocladium sp. on fungus inhibiting of Fusarium sp. has the stages of the competition, lysis and mycoparasit.

This study focuses on the biosynthesis of silver nanoparticles using Banana Raja (Musa Paradisiaca Var. Raja) peel extract. The aim is to determine the effect of concentration differences of silver nitrate (AgNO3) as the precursor on the production of silver nanoparticles. In this study, banana peel extract (BPE) was reacted with AgNO3 solution at several concentrations of silver nitrate solution i.e. 0.125; 0.1; 0.075 and 0.05 M at temperature of 50 °C. The ratio of banana peel extract and AgNO3 solution used was 5:500 (v/v). The stirring was done by using a magnetic stirrer. The reaction took place when the color of the mixture (extract and AgNO3) changed until the color of the mixture became constant. The results of the colloidal silver nanoparticles were characterized using UV-Vis Spectrometer, while the functional groups of the banana extract was analyzed using a Fourier Transform Infra-Red (FT-IR) apparatus. Whereas, the morphology of the silver nanoparticles was studied using a Scanning Electron Microscopy (SEM). The UV-Vis Spectrometer result show that the concentration of AgNO3 which gave the highest absorbance value was at 0.1 M. The SEM micrographs could not clearly show the difference in the morphology of silver nanoparticles samples at different concentrations of AgNO3 solution.

ABSTRACT We studied the feeding behavior and the activity period of three phyllostomid bat species on Musa paradisiaca inflorescences in an orchard located in southeastern Brazil. Glossophaga soricina (Pallas, 1766), Anoura caudifer (É. Geoffroy, 1818), and Phyllostomus discolor (Wagner, 1843) were frequently observed, videotaped, and mist-netted visiting banana inflorescences. Three approaching strategies on banana inflorescences were performed by bats: hovering (glossophagine species), upside landing (G. soricina), and downside landing (P. discolor). A new feeding behavior that consisted in hovering and licking the nectar that dripped from the distal part of a closed bract was observed for glossophagines. Visits occurred throughout the night (from 18:00 h to 05:00 h). However, activity pattern of nectarivorous bat species was significantly different from the omnivorous bat species, with the formers presenting visiting peaks at 21:00 hs and 23:30 hs, and the second at 23:45 hs and 02:30 hs. Dietary specialization, body size, and foraging behavior are important features that are linked to kind of approaching strategies to flowers and activity period of bats. Although bat visits on M. paradisiaca inflorescences are not reproductively important to banana plant, its nectar is a frequent and abundant food source for bats from the family Phyllostomidae, at least in Southeastern Brazil.

The use of banana plant sap as an incision remedy has been carried out through generations in Citatah Village, Cipatat District, West Bandung Regency, Indonesia. This study aimed to examine the ethnobotanical utilization of banana plant sap as an incision remedy. The research was conducted using the snowball sampling technique by the method of structured observation and interviews with 30 respondents. The followings were tools and materials used for the research, a set of stationery, cameras, voice recorders, and laptops. The data obtained were analyzed using qualitative and quantitative descriptive analysis. The results showed that of the thirty respondents who knew the utilization of banana plant sap as wound remedy, only 60% were still using it. Parts of banana plants that were often used by the community was the banana plant shoots by 87% of the total respondents and banana leaf fronds by 13%. There was no specific type of banana used for this wound remedy. However, the type of banana most widely used by the community was ambon Banana (Musa paradisiaca var. sapientum) with a percentage of 20%, kulutuk/manggala banana (Musa balbisiana) 60%, and kepok Banana (Musa paradisiaca formatypica) 20%. Based on the results of the observation and interview, there were at least four benefits of using banana sap, namely preventing infection, sticking wounds, stopping bleeding, and drying the wound. While scientifically, this banana sap can be used as the wound remedy because it contains flavonoid compounds, saponins, triterpenoids, steroids, alkaloids, ascorbic acid, and tannins.

Background:Musa paradisiaca (Banana plant), which belongs to the family of Musaceae, is a well-known herbaceous flowering edible plant. The flower, fruit, and stem part of the plant have been used for nutrients and health benefits.Objective:The aim of this study is to determine the secondary metabolites, proximate composition, minerals, heavy metals, and anti-oxidant activity of three edible parts (flower, unripe fruit, and stem) of Musa paradisiaca.Methods:The content of alkaloid and tannin was determined by simple titrimetric method and colorimetric method was used for the determination of the content of phenol and flavonoid. Association of Official Analytical Chemicals (AOAC) method was used for the determination of proximate composition and the content of trace elements was analyzed by using atomic absorption spectrophotometer. The anti-oxidant activity was determined by 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging assay and hydrogen peroxide (H2O2) radical scavenging assay.Results:The results indicated that three edible parts (flower, unripe fruit, and stem) of the banana plant contained a good amount of secondary metabolites (such as alkaloid, phenol, flavonoid, and tannin) and also primary metabolites (such as carbohydrate, protein, and fat). Banana fruit contained a high amount of energy (261.31 kcal/100g) compared to the other two parts (flower, and stem). Iron, potassium, phosphorus, calcium were present in these three edible parts of the banana plant. Lead was found in negligible amount and arsenic was not detected. Fifty percent of ethanolic extract of three edible parts of the banana plant showed significant DPPH free radical scavenging and H202 radical scavenging activity as compared to standard ascorbic acid.Conclusion:Based on these findings, three edible parts of Musa paradisiaca may be recommended as a good source of nutrients.

Abstract Root zone soil moisture plays an important role in water storage in hydrological processes. The recently launched Soil Moisture Active Passive (SMAP) mission has produced a high-resolution assimilation product of global root zone soil moisture that can be applied to improve the performance of hydrological models. In this study, we compare three calibration approaches in the Beimiaoji watershed. The first approach is single-objective calibration, in which only observed streamflow is used as a benchmark for comparison with the other approaches. The second and third approaches use multi-objective calibration based on SMAP root zone soil moisture and observed streamflow. The difference between the second and third approaches is the metric used to characterize the root zone soil moisture. The second approach applies the mean, which was commonly used in previous studies, whereas the third approach applies the hydrologic complexity μ, a dimensionless metric based on information entropy theory. These approaches are implemented to calibrate the distributed hydrological model MIKE SHE. Results show that the root zone soil moisture simulation is clearly improved, whereas streamflow simulation suffers from a slightly negative impact with multi-objective calibration. The hydrologic complexity μ performs better than the mean in capturing the features of root zone soil moisture.
