Abstract

More and more research results report that exposure to Extremely Low Frequency (ELF) magnetic fields at low intensity can increase cell proliferation. The ELF magnetic field interacts directly with cell membranes, capable of increasing intracellular calcium and under certain conditions affecting cell proliferation. This study wanted to prove the potential of ELF magnetic field radiation with intensity of 200 µT and 300 µT on edamame productivity. The research design used a completely randomized design. The research sample was 250 edamame soybeans of the Ryokkoh-75 variety which were divided into 5 groups. Samples were soaked in warm water for 3 hours and then cured for about 12 hours and exposed to ELF magnetic fields of intensity of 200 µT and 300 µT with variations in exposure time of 60 minutes and 120 minutes. Then it is seeded and planted in the field. Observation of the number of edamame pods and the number of pods was carried out when they were already fruiting, namely day 29 to day 43. The results of the study proved that the number of pods and the number of edamame pods in the group exposed to the 200 µT and 300 µT ELF magnetic fields was higher than the control. It appears that the highest number of fruits and pods occurred in the sample group exposed to the ELF magnetic field intensity of 300 µT. The conclusion is that exposure to the ELF magnetic field intensity of 300 µT has the potential to increase edamame productivity

Abstract

This study aimed to determine the S. oryzae imago number and the level of damage intensity it caused on grains of several rice varieties in Mauponggo District, Nagekeo Regency. The study was conducted at the Pest Laboratory of the Faculty of Agriculture, Nusa Cendana University. The study was laid out in a completely randomized design consisting of five rice varieties as treatments, each was four replicates. A rice grain of 100 grams was put into a plastic jar and infested with a uniform five pairs of S. oryzae. Observed variables included grain water content, number of S. oryzae imago and the percentage of grain weight loss as a measure of damage intensity. Data were subjected to analysis of variance, followed by an Honest Significant Post hoc test at a 0.05 % significance level. The study results showed significant differences among tested rice varieties in both imago populations as well as the level of grain weight loss. IR 64 variety showed the lowest number of imago of S. oryzae and also the lowest grain weight loss while local red and black rice were the highest in both the number of imago and grain weight loss at eight weeks after S. oryzae infestation.

Abstract

This study aims to map the flood inundation and the extent of the inundation in the study area using the HAND model. The data used in this study is DEM. The DEM is used to generate a hydrologic framework, including flow accumulation, drainage network, flow direction, elevation, and flow distance. The method used in this study is the HAND descriptor. The analysis in this study used spatial hydrological analysis and hypsometric analysis using zonal statistical tables in ArcGIS. Based on the results of the analysis of height above the nearest drainage it is known that the Kapuas Sintang sub-watershed has five classes of inundation, namely very high inundation, high inundation, moderate inundation, low inundation, and no inundation. Very high, high, and moderate inundation classes are spread over three sub-districts, namely Sintang, Dedai, and Tempunak sections. Sintang District has the widest distribution, followed by Dedai District and Tempunak District is the narrowest. Prediction of inundation area and flood area with HAND can be used to improve the new mapping model without involving additional data sources. The HAND model is a nice and simple tool that is useful for inundation studies as well as in inundation area prediction.

Abstract

A Inflammation is the basis of pathogenesis of several diseases, both degenerative and non-degenerative diseases. Galangal plants which are commonly found in Indonesia are commonly used as traditional medicines for several diseases and also have secondary metabolite compounds that are useful as anti-inflammatory. In this study, an in silico approach in the form of molecular docking has been applied to 5 compounds derived from the galangal plant to important inflammatory molecular targets such as the cyclooxygenase-2 (COX-2) receptor. Analysis of the biological activity of compounds derived from the galangal plant using the WAY2DRUG PASS prediction server. Prediction results of physicochemical properties of compounds derived from galangal plant using the SWISS-ADME server. This study aims to predict the ability of 5 compounds derived from the galangal plant to inhibit the COX-2 enzyme. Detailed information has been obtained using a molecular docking approach. Docking simulations for 5 compounds derived from the galangal plant have been carried out through the Autodock 4.2 application which is embedded in the MGL Tools 1.5.6 application. The molecular interactions of compounds derived from galangal against COX-2 receptors were visualized using Discovery Studio (Biova) software. Based on the results of the research that has been carried out, it can be concluded that the test compound Galanganal has the best affinity when compared to the compounds Galanganol A, Galanganol B, Galanganol C and Galangin. This can be seen from the bond free energy value of -8.98 kcal/mol and the inhibition constant of 261.59 nM. These results indicate that the Galanganal test compound has potential as an anti-inflammatory agent. However, further research is needed to study more compounds derived from the galangal plant to isolate the best conformation.
