Abstract

Kebutuhan Energi listrik yang diperlukan oleh kehidupan manusia sehari-hari sangat meningkat. Namun penggunaan energi listrik itu sendiri tidak sesuai dengan penggunaan pada umumnya yang membiarkan peralatan elektronik atau penerangan pada sebuah rumah tetap menyala pada saat tidak digunakan.Dari masalah tersebut, maka terpikirlah alat Smarthome yang dapat mengontrol peralatan elektronik dari jauh menggunakan Mini PC Raspberry pidan Smartphone android. Pemanfaatan Raspberry pi adalah untuk mengontrol dan memonitoring peralatan elektronik melalui web yang diperintahkan oleh Smartphone Android yang kemudian dikomunikasikan kepada mikrokontroller AVR ATMega328 untuk menyalakan relay yang tersambung ke perangkat elektronik. Dengan demikian dapat mengontrol perangkat elektronik yang ada didalam rumah dengan cara pengontrolan terpusat dengan sebuah Smartphone android dengan media internet yang meringankan kerja manusia dan mengoptimalisasikan kenyamanan dan keamanaan dari sebuah rumah.

Abstract

This research discusses the design and construction of an automatic mineral water refilling system using fuzzy logic based on the ESP32 microcontroller. The background of this research is the increasing environmental pollution due to the use of disposable plastic mineral water bottles in the campus environment. The system is designed to be able to fill water containers automatically with IR sensor-based control and ultrasonic sensors to detect the presence of containers and water levels. The research method used is the Waterfall method which includes the planning, design, implementation, and system testing stages. The test results show that the system is able to fill water with an average effective volume of 83.2 % of the container capacity, with a safe limit for automatic stopping at a distance of less than 2 cm from the rim of the container. The implementation of Mamdani fuzzy logic allows the system to make filling decisions based on sensor conditions adaptively, resulting in efficient and accurate pump control. Thus, this system can be an innovative solution to reduce plastic waste while supporting efficient water use in the campus environment.

Abstract

The research aimed to evaluate the accuracy of control system simulations using MATLAB Simulink by comparing the results with those from reference journals. This study employed simulations and comparative analysis without any hardware testing. The system model and control parameters were derived from the reference journal, and simulations were conducted to obtain the system response in the form of time-domain waveforms. The analysis focused on comparing key system response characteristics, including target point attainment speed, overshoot, and steady-state stability. The results revealed that the waveform of the simulation response closely matched the patterns observed in the reference journal, with a high degree of agreement in terms of response characteristics. MATLAB Simulink simulations were validated as a reliable tool for system response analysis, as the small differences observed did not significantly impact the overall conformity of the response characteristics. This study confirms that MATLAB Simulink is effective for validating control system performance based on reference journal simulations.
