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.

Abstract

Heavy metal pollution is still a serious problem today. One method that can be used to remove heavy metal content from water is the adsorption method. In the adsorption method, the choice of adsorbent is very important to optimize the adsorption process. One of the materials that can be used as an adsorbent is tea waste. Tea waste contains cellulose, which can be used to bind heavy metal ions. This research was conducted to synthesize adsorbents using tea waste and then test their ability to adsorb lead ions. The adsorbent synthesis process is divided into several stages, namely washing, drying, refining, soaking in HCl solution, and drying again. The results of the adsorption tests conducted found that the tea waste adsorbent could remove 99% of the lead metal ion content in the water. The conclusion from these results is that the synthesis process has succeeded in making tea waste adsorbent that can adsorb lead ions in water.
