Abstract

Wind turbine blades are using to drive generator, in the blades there are airfoils that can produce lift force. One that affects the airfoil performance is angle of attack (AOA). This study was conducted to analyze the aerodynamics of the NACA 4412 semi inverse-tapper airfoil. The material is using PVC with an airfoil size (length 20 cm, a base chord 13.26 cm and a tip chord 12 cm) at wind speed 3 m/s, 5 m/s, 7 m/s, 9 m/s and 12 m/s. The test was performed by experimental method by using wind tunnel and simulation with solidwork application, the results of two methods are compared for analysis. The results of research show that more fast the wind speed that strikes the airfoil, more greater the value of lift force and drag force, this is directly proportional to the value of lift coefficient and drag coefficient, the best angle of attack for airfoil type NACA 4412 semi inverse-tapper form angular position angle of attack 5 ° at wind speed 3 m/s. Keywords : angel of attack, HAWT, NACA 4412, semi inverse-tapper

Abstract

Solar energy can be converted into electrical power through photovoltaic (PV) technology, commonly referred to as solar panels.  As a result, the implementation of a monitoring system is crucial to mitigate battery degradation caused by excessive discharging. This study employs a research and development (R&D) approach. The off-grid solar power monitoring system installed at SMPN 04 Tempurejo is designed to facilitate maintenance and enhance system reliability. By integrating Internet of Things (IoT) technology, the monitoring system allows for real-time tracking of voltage, current, and power output from the PV system via smartphone access, irrespective of location. Consequently, the IoT-based monitoring system significantly improves the management and oversight of the off-grid solar power system at SMPN 04 Tempurejo.

Abstract

Arduino UNO R3 is one of the cheapest and easiest microcontroller boards that has great potential to be used as a basis for the measurement system. This study aims to develop measurement system of crude oil capacitance by using IDCs(Interdigital Capacitors). By knowing the value of crude oil capacitance, the crude oil permittivity value can be calculated. The crude oil permittivity value data is extremely needed in making crude oil heating systems using microwaves. The study used IDC sprinted on a PCB board with a copper layer as the electrode. Then, the system measurement results were compared with the results of PM 6303 RCL meter Phillip type A frequency measurement of 1 kHz which was used as reference data to determine the extent of measurement errors. From the results obtained, it is known that the error value of the Arduino UNO R3 based capacitance repeatability measurement is 0.47%. While the results of the linearity test measurement of crude oil capacitance measurement of temperature increases using the Arduino Uno-based IDCs sensor, the R2 value is 0.87. Thus it can be seen that the Arduino UNO R3-based capacitance measuring device has quite good sensor characteristics.

Abstract

Closed-house broiler chicken farming enhances productivity and animal welfare by maintaining optimal environmental conditions. However, reliance on grid electricity for air control systems increases operational costs and environmental impact. This study investigates the implementation of a solar-powered air control system to regulate temperature, humidity, and ventilation in closed-house broiler farming. The system integrates photovoltaic (PV) solar panels, energy storage, and a smart control mechanism. The system's performance is evaluated based on energy consumption, solar energy generation, and environmental parameters. Results show the system effectively maintains optimal broiler growth conditions while reducing energy dependence. Energy savings of up to 10% are achieved, leading to lower operational costs and improved sustainability.The findings demonstrate the feasibility of solar-powered solutions in broiler farming, reducing greenhouse gas emissions and enhancing farm resilience. Future work will explore IoT integration for real-time monitoring and further energy optimization.
