Abstract

The development of a system designed in such a way as to become security that makes everyone feel the need to ensure the safety of everything that includes himself, both from his activities and the assets he owns. This system uses an RFID Reader with a frequency of 13.56 MHz and an ATMega328 Microcontroller that acts as a controller or circuit controller and is tested with hardware and software testing to determine the performance between the software and hardware of the device. This research shows that the RFID Reader can detect E-KTP with a maximum distance of 2.5 cm, and the solenoid will lock back after 3 seconds. The utilization of Renewable Energy is currently a priority in carrying out technology development, one of which is solar energy with solar panels as electrical energy. This research supports efforts to develop energy-based technology that is converted with various supporting components and system authentication designed using the use of control security systems both in terms of administration and information technology-based on population data and uncontrolled system prototypes.

Abstract

The development of a system designed in such a way as to become a security that makes everyone feel the need to ensure the security of everything that includes himself, both from his activities, and the assets he owns. The magnitude of the value of an asset owned, which encourages everyone to implement an effective and efficient security system as protection. One of them is in Locker cabinets which generally still use a manual locking system. The purpose of this research is to design a locker cabinet door security system by utilizing the Arduino Uno R3-based keypad and E-KTP. This system uses an RFID Reader with a frequency of 13.56 MHz and an ATMega328 Microcontroller which acts as a controller or circuit controller and is tested with hardware and software testing to determine the performance between software and hardware on the device.

Abstract

This goals as a shape of assessment of laboratory-primarily based totally realistic getting to know for guides completed withinside the Power System Analysis laboratory. This form of studies is a application assessment studies with a descriptive quantitative studies approach. The approach in accumulating studies statistics is with the aid of using the usage of a questionnaire given to academics and college students who take the AST direction practicum according with the Context, Input, Process & Product (CIPP) version assessment instrument, similarly to the questionnaire statistics series is completed with the aid of using commentary throughout the practicum. In this have a look at there had been eleven instructors and 15 college students who had been used as samples. From the sample, it indicates that the cost acquired with the aid of using the practicum lecturer in phrases of contextual is 84.090%, in phrases of enter is 90.150%, in phrases of technique is 89.770% and in phrases of product is 87.12%. From the scholar aspect, the effects finished primarily based totally at the expertise of realistic getting to know withinside the laboratory in phrases of contextual are 80.00%, in phrases of enter 83.660%, in phrases of technique 85.830% and 79.160% in phrases of product. Based at the effects of calculations from the aspect of the lecturer and college students that digital laboratory-primarily based totally realistic getting to know goes properly in order that college students` expertise is withinside the properly category.

Abstract

The development of modern organizations requires individuals not only to possess professional competence but also to demonstrate ethical behavior in carrying out their professional responsibilities. However, many organizations still face challenges related to inconsistent ethical behavior among professionals, indicating a gap between ethical standards and actual practice; therefore, this study aims to examine the role of self-concept as a determinant of ethical behavior in professional settings. Ethical behavior in organizations is influenced not only by external regulations such as professional codes of conduct but also by internal psychological factors within individuals. One of the most important internal factors is self-concept, which reflects how individuals perceive and understand themselves in relation to their roles and responsibilities in the workplace. This research employs a qualitative approach, using in-depth interviews and documentation to obtain comprehensive insights into individual perceptions and experiences of ethical behavior in professional settings. Purposive sampling is used, and the data are analyzed through thematic analysis. The results indicate that individuals with a clear and positive self-concept tend to demonstrate stronger moral awareness, greater responsibility, and more consistent ethical decision-making, with key themes including self-awareness, moral responsibility, ethical consistency, and organizational support. Furthermore, organizational culture and ethical leadership reinforce the development of self-concept that supports ethical behavior. This study provides empirical insight into the psychological basis of ethical behavior and offers practical implications for strengthening organizational integrity.
