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.
