Abstract

The purpose of this study was to determine the effect of motivation and work discipline on employee performance PT. PLN (Persero) Central Load Regulator Unit of Java, Madura, and Bali at the Office of the DKI Jakarta and Banten Load Regulator Implementation Unit, both partially and simultaneously. The method used is the Quantitative Associative method. The population in this study were employees at PT. PLN (Persero) Central Load Regulator Unit of Java, Madura, and Bali at the Office of the DKI Jakarta and Banten Load Regulator Implementation Unit.

This research aims to determine the influence of work motivation and discipline on employee performance at "PT Berkat Cahaya Novena Bogor". The method used in this research is a quantitative method. The total population in this study was 67 respondents. The sampling technique used saturated sampling and a sample of 67 respondents was obtained. Data analysis uses validity tests, reliability tests, classical assumption tests, regression analysis, correlation coefficients, coefficients of determination, and hypothesis testing. The results of this research are that the motivation variable partially has a positive and significant effect on employee performance with a calculated t value of (5,840 > 1.998) and a sig value of 0.000 < 0.05. This shows that H0 is rejected and H1 is accepted. The Work Discipline variable partially has a positive and significant effect on employee performance with a t value of (5,895 > 1.998) with a sig value of 0.000 <0.05. This shows that H0 is rejected and H2 is accepted. Based on the F (Simultaneous) hypothesis test, it can be seen that the F value is (23.315 > 3.140) and the significant value is 0.001 <0.05. So it can be concluded that H0 is rejected and H3 is accepted. This means that Motivation and Work Discipline simultaneously have a positive and significant effect on employee performance at PT Berkat Cahaya Novena Bogor.

Abstract

Utilizing the time needed in a work process, the speed of data transfer is direct human work, so IoT (Internet of Things) is currently the answer to all needs that replace direct physical functions, through data transfer using internet network media which is assisted by a microcontroller device to implement many things in everyday life, both in the industrial world, laboratories, agriculture, health and household needs. This Internet of Things (IoT) based lighting control system application uses an Arduino Uno as a microcontroller and an Android application as a control tool. This system is used to control the lights on or off. Apart from that, the design of this system also uses a relay which is used to connect the light to the system. From the results of testing and analysis, the control of electronic equipment in this light control system operates according to the commands given. As long as the system is connected to the internet network stably, there will be no problems with the IoT (Internet of Things) based light control system using Arduino Uno with voice commands using the Bluetooth voice application.

Abstract

Non-linear equations are one of the fundamental problems that often arise in various scientific disciplines, such as physics, engineering, economics and computer science. Solving non-linear equations analytically is often not possible due to the complex nature of the functions involved. Therefore, numerical methods such as Newton-Raphson and Fixed Point Iteration are the main choice to approach solutions with high accuracy. This research aims to analyze the performance of the two methods in solving systems of non-linear equations. The analysis is carried out by comparing aspects of convergence speed, solution accuracy, and stability to changes in initial values ​​and the nature of the function being analyzed. The Newton-Raphson method is known for its fast quadratic convergence, but requires derivatives of functions that are not always practical to calculate. Meanwhile, the Fixed Point Iteration method is simpler in implementation, but has slower linear convergence and relies heavily on the selection of recursive functions and initial values. The research results show that the Newton-Raphson method is superior in terms of convergence speed, especially for functions with derivatives that can be calculated easily. On the other hand, Fixed Point Iteration is more flexible for use on functions without explicit derivatives, although it requires more iterations to achieve the same accuracy. This research provides guidance for practitioners in choosing the most appropriate numerical method based on the characteristics of the problems faced, so that it can be implemented optimally in various application fields.
