The distribution of Trichoderma sp (TBPH isolate) in litter layers of Acacia mangium was observed in two years’ old of health standing (2S) and Ganoderma sp-attacked standing (2G). The objectives of this research were to observe Trichoderma sp distributions in leaf litter layers and to determine of antagonistic ability of Trichoderma sp TBPH against Ganoderma sp (GBR isolate). Trichoderma sp in sawdust medium was spread above of F litter layer in 50 x 50 cm area. Total populations of Trichoderma were observed each month during eight months. Antagonistic activities of Trichoderma sp TBPH against Ganoderma sp GBR were tested by dual test method on PDA and PDA with litter powder (PDAS) media.  The results showed that populations of Trichoderma sp were fluctuating and the highest population on both standings of F layer   and were followed by H and L layers. Fluctuations of Trichoderma sp population on L layer were tended to follow rainfall fluctuations while those on F layer were tended to follow litter pH fluctuations. Antagonistic test showed that inhibition percentage of PDAS medium was lower than those of PDA medium indicating litter amendment on media being causes of lower antagonistic activities of Trichoderma sp.

The performance of diagnostic X-ray machine should be checked to determine if the dose received does not harm a patient and produce a good image and provide diagnostic information in a timely and accurate, therefore there are necessary for quality control activities on the machine X-ray. Factors that affect the dosing and imaging results, among others, the amount of the provision of current and voltage. From the research shows that the value of the output voltage generated is not much different from the value of the input voltage with a percentage value below 5%. This value shows a good output machineX-ray because it is still under the maximum tolerance limit of 10%. So the overall results of observations on the machineX-ray is in hospital, the quality control measurements gave values still within safe limits. Then by giving a higher input voltage turns also affect the amount of energy produced, thus affecting also absorbed dose X-rays are produced.

Walur is one of the carbohydrate sources that can be explored because it can be grown in any area with out special treatment. However, walur has limitation for direct consumption, because it contains calcium oxalate. The purposes of this study were to determine the chemical character (macronutrient content), calculate glycemic index and get the proper washing techniques to elimin ate calcium oxalate of walur. Macro nutrients content studied in this research include carbohydrates, fats, protein, star chand crude fiber. Analysis of macronutrients has been chemically done, while the glycemic index was measured by in vivo using glucose as a standard. Elimination of calcium oxalate was conducted by washing the fresh walur tubers using a solution of0.01NHCl-NaOH, 5% NaCl, and solution of lemon-lime. The content of oxalate before and after washing was analyzed by permanganometry method. The results showed that walur containing 4.34 ±0.07% of reducingsugar,3.24 ± 0.06 % of not-reducing sugar, 11.27±0.40 % of crude fiber,0.03±1.05 % of starchand0.57±0.01 % of protein. Qualitative analysis of fatty acids showed that hexade canoicacid, octade cadienoicacid, and the acide icosatetranoic were detected in high concentrations. The glycemic index valueof walur was relative lylow, about of 16.9. In addition, washing technique using a solution of lemon-lime was the most excellent technique and can reduce the oxalate content up to61.82%.Fromthis research, it can be concluded that walur can be used as food substitute esrice after washing treatment using lemon-lime solution to remove the calcium oxalate content.

Evolutionary algorithm is a precise algorithm used in solving complex optimization problem as it is part of heuristic method. Evolutionary algorithm, like many other algorithms, also experiences a premature convergence phenomenon, whereby variation is eliminated from a population of fairly fit individuals before a complete solution is achieved. Therefore it requires a method to delay the convergence. A specific method of fitness sharing called phenotype fitness sharing has been used in this research. The aim of this research is to find out whether fitness sharing in evolutionary algorithm is able to optimize TSP. There are two concepts of evolutionary algorithm being used in this research. the first one used single elitism and the other one used federated solution. The two concepts had been tested to the method of fitness sharing by using the threshold of 0.25, 0.50 and 0.75. The result was then compared to a non fitness sharing method. The result in this study indicated that by using single elitism concept, fitness sharing was able to give a more optimum result for the data of 100-1000 cities. On the other hand, by using federation solution concept, fitness sharing can yield a more optimum result for the data above 1000 cities, as well as a better solution of data-spreading compared to the method without fitness sharing.

The reliance on ground water is necessary to ensure that there are significant quantities and high quality of water. Ground water resources at coastal urban forest in Banda Aceh were assessed by using VLF method. VLF techniques measured the perturbations in a plane wave radio signal (15-30 kHz) being emanated from one of several world-widde radio transmitters and was also used for submarine communications. Apparent resistivities and phases were measured along 340 m profile at the area. Two frequencies (27700 and 29000 Hz) were used in this measurement. The data were modeled by using 2D inversion code of Rebocc. The model showed clearly ground-water map of the subsurface. Based on the model, aquifer layers were indicated by low resistivities zones (40 – 400 Ω-m). However, the ground-water resources in the area were dominated with high salinity water at depth under 140 m. Therefore, extended geophysical exploration methods were water aquifer in the area to watering the forest.

Traditionally the magnetotelluric data are collected on 2D profile perpendicularly across an assumed geological strike. However there is no guarantee where the chosen strike is exactly or nearly same as true geoelectrical strike. For this purpose, 2D synthetic magnetotelluric impedance data of a simple 2D model were generated along a profile across the model. The data were inverted on various presumed strike in order to study how far the inverted model is deviated when the presumed strike is moved away to the true strike. By the aim, first the data were inverted as measured on 2D profile perpendicularly across true strike in order to see how the inversion works in the ideal case. Thedata were also inverted as measured on 2D profile perpendicularly across an assumed strike. The presumed strike deviated 60 degrees to the true strike was selected as an example of extreme case. The model inverted from the extreme presumed strike data is compared to the actual one. The inversions on determinant and combined TE and TM modes have been done as well for model resolution comparison.
