Background: The essential oil contained in basil leaves can help in the wound healing process. Wound healing process consists of inflammatory, proliferative and remodeling phases. Basil essential oil has been shown to have an anti-inflammatory effect so that it can accelerate the wound healing process. Objective: To determine the effect of basil essential oil extract gel in the number of macrop…
Tailing is one of waste that’s produced by mining activity at PT. Freepot Indonesia (PT FI) and it also called as sirsat, which is the representing abbreviation from sand in mining. This Sirsat is placed at Modada ( Modified Ajkwa Deposition Area), that’s an area which is modified and managed operation of sirsat and, broadly about 235 kilometres, limited by West Levee and East Levee. The Sy…
Upwelling is a phenomenon that often occurs in the oceans. Upwelling itself is defined as the process of increasing the mass of seawater in the deep sea layers to the surface caused by a void of seawater masses on the surface. The existence of this upwelling phenomenon causes an anomaly that causes many impacts on the oceans and the earth's atmosphere in an area. The Ocean Dipole Index (IOD) is…
This study analyzes the GFR core with a CANDLE burn up strategy with a variety of fuels, Uranium Carbide (UC) and Uranium Nitride (UN). UC and UN are used as starter fuel and natural uranium is used as fresh fuel. The simulation uses the Monte Carlo method in the OpenMC program and uses the ENDF/B-VIII.0 library. The calculated physical parameters are conversion ratio, effective multiplication …
The mass of cold seawater from the seabed is lifted up to the surface is referred to as upwelling. Due to the influence of Ekman Transport and the Coriolis Force. Some of the parameters used to review the occurrence of upwelling in the Positive IOD event are Sea Surface Temperature, Sea Level, Wind and Chlorophyll-a. Descriptive method as the method used to analyze the results of the image of e…
