Abstract

The library holds the meaning as a place where various information is disseminated, whether printed or recorded in various media such as books, magazines, computers, and others. The library is a public place that provides information that can be visited by anyone, both children and adults are allowed to visit the library. Not apart from library visitors consisting of children to adults, it is not uncommon for disorder to occur inside the library, one of which is noise that can disturb the tranquility inside the library. Unexpected or unwanted noise because it does not match the library context can cause discomfort and disturbance to library visitors. Therefore, based on the considerations above, researchers try to propose research entitled "Design of Noise Detection Device with Sound Sensor Mic in the Library Based on Arduino". The system used utilizes the Arduino UNO microcontroller equipped with DF Player and other supporting devices so that in practice this tool can provide warnings when noise reaches a certain level in order to maintain noise below the predetermined threshold. The result of this research is that this system can operate by detecting the noise level with the KY307 mic sensor then using the Arduino microcontroller to analyze and process sound data to produce information about the noise level. This data is then displayed on the LCD screen and connected to an audio tweeter to provide a warning if the noise level exceeds the threshold.

Abstract

A good company or agency has disciplined employees and good employee work scheduling. This is very much in line so that a company needs to create effective and appropriate employee work scheduling. SMK Ma'arif Bantarkawung itself still uses a manual system for employee scheduling. The purpose of writing this thesis is to increase knowledge to readers about genetic algorithms and teacher employee attendance using fingerprints. This algorithm works through several stages, initialization, reproduction, evaluation, selection. At the selection stage, individuals who have better traits will be selected to produce the next generation that is also better. According to several studies, scheduling is the process of scheduling the process of organizing, selecting, and determining the time of use of existing resources to produce the expected output within the expected time. The conclusion that can be drawn is the development of a schedule maker feature system, where school managers must enter the name, teacher code, hours, and subjects taught. Change schedule feature, where data managers only need to change data if they change semesters and subject teachers clash. Change data feature, where data managers only need to change data if subject teachers clash. The results of optimizing the absence of teachers of SMK Ma'arif Bantarkawung employees using genetic algorithms show that the scheduling of teacher absences of SMK Ma'arif Bantarkawung employees aims to create a schedule automatically, displaying the day and time on the teacher's schedule. This genetic algorithm completes the scheduling optimally, so that there is little schedule mismatch.

Abstract

The availability of fossil energy is increasingly in crisis due to its continuous use. The best alternative to anticipate this is new renewable energy (EBT). Minihydro Power Plant (PLTM) is a small-scale power plant that uses water power as the main medium to drive turbines and generators, the water comes from rivers by utilizing the height of the waterfall and the amount of water discharge. By knowing the water discharge value, it will later be analyzed with the power value produced by the generator. The type of research used is quantitative analysis research and pre-experimental one shot case study using the help of IBM SPSS Statistics 25 for Windows laptop software. Based on the results of simple linear regression analysis on summary, ANOVA and coefficient models. In the summary model, it is known that the R Square value is 1,000, which means that the influence of the independent variable (water flow) on the dependent variable (power) is 100%. And this is confirmed by the coefficient results which show a significance value of 0.000 < 0.05, which means that the water discharge has an effect on the power produced by the generator. The higher the water discharge value, the higher the power produced.

Abstract

The operation of the transformer power distribution is the center of the transmission and distribution system. Given the almost continuous hard work of the transformer, its operation needs to be considered to prevent several disturbances that can reduce the optimal work of the transformer. One of the disturbances that can be found in the substation transformer is the hot-spot temperature at the terminal connection between the conductor cable and the equipment at the substation. This temperature is closely related to the protection and reliability of the system in the switchyard. To overcome the problems that occur in the transformer, especially the 150 kV Kalibakal Purwokerto Substation regarding the hot spots that occur at the transformer conductor bay connection. Routine temperature checks are carried out every day at the transformer connection point using a Thermovisi Flir E60 thermal imager measuring instrument that can determine the temperature value at the conductor connection clamp by looking at the infrared light from the tool. The results of the test evaluation carried out in this thermovisi method use the calculation of the temperature difference (∆T) between the clamp and the conductor, the results obtained are that none of the temperatures exceed >10˚C. The calculation of the emissivity value using Stefan Boltzman's law obtained an average emissivity of 0.506, which means it is included in the temperature range in accordance with the Standard Reference Material (SRM) (aluminum emissivity 0.5). Precision testing with a precision percentage expressed by the Coefficient of Variation (CV) obtained from 45 test points is 0.23%, this result can be categorized as a good result from the CV value standard of <2%. The calculation of the accuracy test found a result of 99.88%, which means that the points tested are still in good condition.

Abstract

PT Bintan Alumina Indonesia (BAI) is a company engaged in many fields, one of which is the Steam Power Plant (PLTU). PLTU itself is a generator that utilizes the kinetic energy of steam to produce electrical energy. There are various fuels used in PLTU, such as gas, oil, coal, biomass, and others. One of the problems that has occurred at PLTU BAI is the temperature drop that occurs in the main boiler component, namely the feed water. Feed Water itself functions as a place for channeling the working fluid which will be converted into steam. This problem causes an increase in coal consumption as a furnace heating material. Monitoring of the decrease in feed water temperature is carried out using a Distributed Control System (DCS). This study explains the methods used and the research design concerning the effect of lowering the feed water temperature on the flue gas temperature. The results of this study are the temperature difference of 20°C to 30°C, the feed water temperature is lower when compared to the normal temperature. The drop in exhaust gas temperature caused by a decrease in the temperature of the feed water so that the exhaust gas temperature also drops. The impact of fluctuations in the feed water temperature on the parameters is that the flue gas temperature drops, the economizer temperature drops, the steam flowrate decreases, and uses a large amount of coal resulting in a large amount of slag left over from combustion.
