Abstract

Craniospinal is known as the method to kill the cancer within a wide radiation area, starting from the cranial to spinal nervous system. In the case, the cancer has spread through the fluid of cerebro spinalis, such as medulloblastoma. We carried out the research to determine the isodose curve in medulloblastoma craniospinal patients and DVH (Dose Volume Histogram) statistic in the OAR (Organ at Risk) by using 3D-CRT radiotherapy technique. To conduct the radiative treatment, we used the moving Junction method in which the radiation was divided into three Iso section, i.e.: Section Iso brain with gantry 90° and 270°, Section Iso thoracic with gantry 0°, and Section Iso lumbar with gantry 0°. Then, we analyzed the isodose curves and DVH statistics created by photon beams of 6 MV and 10 MV with and without considering the dose absorbed by OAR. We found that the isodose curves created with considering the OAR dose were better than those created without considering the OAR dose. We also found that the dose absorbed by OAR was within the tolerance limit stated in ICRU guidelines. Kata Kunci: DVH of statistic, Isodose curve, Craniospinal, Medulloblastoma

Abstract

Light intensity is the intensity of light emitted as a light source in a certain direction. In a building, human safety depends on the level of lighting, and helps create a creative visual environment. Broadly speaking, light sources are divided into two, namely natural light and artificial light. According to the Indonesian National Standard (SNI), the recommended minimum lighting strength for lecture halls is 250 lux. Therefore, this study aims to determine whether the lighting intensity of the lecture hall in the SLC building meets the SNI standard, and to determine the relationship between natural and artificial fluxes in the SLC lecture hall of the Faculty of Mathematics and Natural Sciences, Mulawarman University. This study uses the method of measuring the intensity of illumination with a luxmeter measuring instrument at predetermined measurement points. The results obtained in this study, namely, the intensity of natural and artificial lighting in the lecture hall of the SLC building did not entirely meet the SNI standard, because in use without lights and 6 lights the point is far from the light source. The relationship between natural and artificial lighting flux corresponds to changes in the intensity of natural and artificial lighting with time, the greater the change in lighting intensity with time, the greater the lighting flux in the lecture room with time.

Abstract

Control valve is a tool in the oil and gas industry that works by relying on actuators as a driving force. For example, pneumatic actuators work with air pressure as driving energy, and standard signals are used for pneumatic. The signal is converted into a current signal using fuzzy as an application of artificial intelligence systems in the industrial sector. The method used in this study is the utilization of fuzzy logic with the Mamdani method using the software MATLAB. The results will be compared with data from companies and P/I simulation data. Pressure pneumatic algorithm system fuzzy by paying attention to the range of signals used. Company data and P/I converter simulation data are not much different, but the line equation obtained is slightly different. Meanwhile, the fuzzy logic data has slightly different data from the previous data caused by the rules of the fuzzy. Thus, the use of fuzzy logic pressure pneumatic signals to flow signals can be said to be quite capable of being used in these systems by paying attention to the range of signals and rules needed. The comparison results that have been tested have data results that are not much different based on the difference in the value of the current signal and the error value obtained below 2.5%.

Abstract

Bench press is a form of powerlifting exercise that aims to increase the strength and endurance of the muscles of the upper body, that is, the muscles of the chest, arms, and shoulders. The characteristic of the bench press exercise is to lift or push the weight using both hands in a supine position. The purpose of this research is to determine the effective angle required for lifting weights with the least amount of thrust (biomechanics aspects). The research steps were carried out in four stages, namely: first, designing biomechanics mathematical equations; second, experiments on people doing bench press movements; third, processing biomechanics data; and fourth, analysis and discussion of biomechanics data. According to the study's findings, an effective angle was obtained by analyzing the thrust to lift the barbell, that is, the angle flanked by the upper and lower arms, which is approximately 89°-114° for those who use the smallest thrusts on the grip: 0.4 m, 0.5 m, and 0.6 m. It can be concluded that the wider the distance between the grips, the greater the thrust required.

Abstract

One of the musical instruments in the gamelan is the bonang instrument. A bonang is a musical instrument with a small, hollow structure. This study was conducted to determine the relationship between the surface area of the bonang pot and the frequency of the basic tone generated, and to find out the results of the variety of sounds on the bonang musical instrument. A bong that was stopped only after the sound was muted was applied to record the audio directly. Using AudioCyti software, a surface area and frequency are then measured, and the output signal is measured using the Fourier transform method. The parameters measured are surface area and frequency. In accordance with the results of this study, there is a connection between surface area, or the basic frequency, which is achieved with a frequency of 0.88363, and frequency, which is obtained with a frequency of 0.986053. So, it is concluded from the study that has been carried out that the surface area has an influence on the frequency. Users can determine the frequency of a bonang musical instrument's fundamental tone by varying its frequency values from lowest to highest and analyzing the output signal with audiocyti software. As a result, each sound produced by a bonang pot is distinct and nonsequential. This is because, like modern musical instruments, a bonang laras slendro does not yet have a set tone frequency.
