Abstract

Energy demand in Indonesia, as well as globally, continues to increase. Hydroelectric power plants (HEPP), along with steam power plants (SPP) and gas power plants (GPP), play a crucial role in electricity supply. Indonesia, an archipelagic country located along the equator, is uniquely positioned with abundant wind energy potential. Remote communities, which often face challenges in accessing electricity, could benefit from utilizing this renewable resource. The ventilator turbine, primarily designed for air circulation, is installed on rooftops of residential and industrial buildings to function as ventilation. Previous research has explored the use of ventilator turbines as wind-powered electricity generators, yet several improvements are still needed. This research focuses on enhancing the performance of the ventilator turbine by connecting the wind turbine to a generator through a V-belt system, which maximizes the rotational speed and energy output. The generator then produces electricity that can be utilized by local communities, providing a sustainable and eco-friendly energy solution. This research aims to contribute to community empowerment by introducing renewable energy technologies that can be locally maintained and managed, thus promoting economic independence in rural areas.

Abstract

The container transport system plays a crucial role in facilitating cargo transfer by simplifying the unloading process to make it more effective and efficient. In container vessel operations, fuel consumption management is a critical aspect that significantly impacts operational costs, accounting for approximately 70% of the total expenses. Therefore, shipping companies must closely monitor fuel consumption to prevent wastage. Without an effective monitoring system, the management cannot track fuel consumption in real-time, which may lead to misuse by crew members. This study aims to implement a flowmeter sensor technology based on Outseal PLC for automatic monitoring of fuel consumption on vessels. The data from the flowmeter sensor will be transmitted to a web server, allowing authorized personnel to access the information for transparent and accurate oversight. The test results of the flowmeter sensor show low error rates of 1.23%, 2.07%, and 2.06%. Thus, this system proves to be effective as a real-time fuel consumption monitoring solution for auxiliary engines, with a reading interval of approximately 1 minute and 58 seconds per liter. This research contributes to improving energy efficiency in the maritime sector while empowering the shipping community with technology that can be accessed by relevant parties, as part of a broader community service initiative.

Abstract

The effectiveness and efficiency of motor speed control are critical for sustainable development, particularly in community-based industries. A control system, defined as a mechanism to regulate, command, and manage a system's state, plays a significant role in optimizing energy usage. DC motors, widely utilized for their linear torque-speed characteristics and high efficiency, are preferred due to their simple control systems and minimal hardware requirements. This research focuses on developing and implementing Linear Quadratic Regulator (LQR) and Linear Quadratic Tracking (LQT) control systems for DC motors, particularly in community service programs aimed at improving energy efficiency in small-scale industries or maritime applications. The study was conducted in several stages, starting with a comprehensive literature review on first-order mathematical modeling, LQR, and LQT methodologies using journal articles, papers, videos, and books. Subsequently, DC motor specifications were obtained from datasheets and converted into first-order mathematical models. The LQR formulation was applied to derive state-space models through MATLAB programming. Experimental results demonstrate that LQR and LQT controls significantly enhance motor speed optimization while minimizing input signals. However, the introduction of noise or disturbances in the system caused instability, resulting in non-uniform motor speed. The study highlights the potential of LQR and LQT controls to improve energy efficiency in DC motor applications within community service programs. These findings can benefit communities by reducing operational energy costs and supporting sustainable technology adoption.
