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

This study investigates the influence of duty cycle, inductance, and capacitance variations on the performance of a buck converter through simulation using PSIM software. The research aims to quantify how these parameters affect output voltage and ripple, which are key factors in achieving efficient and stable DC–DC conversion for renewable energy applications. The converter was modeled with an input voltage of 48 V, an intended output voltage of 24 V, and a switching frequency of 20 kHz. Simulation results show that the output voltage increases linearly with the duty cycle. At a 50% duty cycle, the converter achieved an output voltage of 23.9 V, confirming accurate voltage regulation. Furthermore, ripple voltage was found to decrease significantly with higher inductance and capacitance values, reaching a minimum of 0.1 V when L is 750 μH and C is 1,250 μF. These results demonstrate that optimizing LC parameters can substantially improve voltage stability and filtering efficiency. The findings provide practical design guidance for high-efficiency buck converters used in renewable energy and power electronic applications.

Abstract

Permanent Magnet Synchronous Generators (PMSGs) are widely used for converting mechanical energy into electrical energy through electromagnetic induction. Unlike conventional generators, PMSGs utilise permanent magnets to generate the excitation field, eliminating the need for external excitation coils. This study investigates the effects of rotor teeth width variations on the performance characteristics of a 12-slot, 8-pole PMSG using Finite Element Method (FEM) simulations. Specifically, the influence of rotor teeth width on flux density and back electromotive force (EMF) constant are explored. Three different rotor teeth widths, 5 mm, 7.5 mm, and 10 mm, are considered, and their impact on the generator's performance is evaluated. The FEM simulations reveal that increasing the rotor teeth width leads to a significant increase in the back-EMF constant values. The smallest back-EMF of 12.057 V and the lowest constant are observed for the 5 mm rotor teeth width, while the largest back-EMF of 20.774 V and the highest constant correspond to the 10 mm rotor teeth width. These findings highlight the importance of optimising rotor teeth geometry in PMSGs to achieve desired performance characteristics.

Abstract

Permanent magnet synchronous generators (PMSG) converts mechanical energy into electrical energy through electromagnetic induction, with the excitation field generated by permanent magnets instead of coils. This paper investigates the effects of varying magnet thickness and width on the back electromotive force (back EMF) of an 18-slot 16-pole PMSG using finite element method (FEM) simulations. The aim is to understand how these geometric parameters influence the back EMF values, which are crucial for generator design and performance evaluation. The FEM modelling results show that a 5 mm magnet thickness yields the highest back EMF value of 130.47 V, while a 15 mm magnet width produces a back EMF of 100.65 V. Additionally, the back EMF constant (KE) is maximized at 0.79 V·s/rad for a 5 mm magnet thickness and 0.55 V·s/rad for a 15 mm magnet width. These findings provide insights into optimising magnet dimensions for improving the efficiency and output characteristics of PMSGs in various applications.
