Abstract

This This study aims to examine the optimization of the size and thickness of piezoelectric as the main element in harvesting rain energy from raindrops. The method used is an experiment by varying the size of the piezoelectric (1x1 cm, 3x3 cm, 5x5 cm) and thickness (0.2-0.5 cm) which is installed on the roof of the building model. The research variables measured are voltage and electric current using a multitester three times for data validity. The data is processed to determine the output electrical power and efficiency of the piezoelectric energy conversion system. The results of the study and experiments show that the size and thickness of the piezoelectric affect the output electrical power and efficiency. The results of this study found that the optimal dimensions of the piezoelectric determine the maximum output electrical power and efficiency.

Abstract

The increasing demand for energy encourages the development of renewable energy sources, but the utilization of rain energy in Indonesia is still limited. This literature study examines the effect of rainfall intensity and water droplet size on the electrical output of polycarbonate piezoelectrics. The intensity variation is set at less than 5 mm/hour (light rain), 5-20 mm/hour (moderate rain) and 20-50 mm/hour (heavy rain), with droplet sizes of 2.5 mm, 5 mm, and 7.5 mm. The experimental method in this study was carried out by comparing the differences in rainfall intensity and the size of raindrops that fell on the roof that had been installed with a piezoelectric. The raw data measured were voltage and electric current. The results of data processing are in the form of piezoelectric performance, namely electrical power and efficiency. A review of the variations in rainfall intensity and raindrop size shows a relationship between the kinetic energy of the droplets and the piezoelectric output voltage.

Abstract

Hydrogen gas can be produced from wet hydrogen generators (GHB) and dry hydrogen generators (GHK). Both hydrogen generators are powered by a 50 Wp solar panel (PV). The aim of this research is to study the performance comparison of GHB and GHK in producing hydrogen gas flow rate and system efficiency to determine the more optimal system. The research began with a literature study and designing both generators, which underwent trials to obtain a research equipment system that adheres to the theory and concepts of GHB and GHK. Experimental methods were carried out by direct measurements of input and output variables from the solar panel as well as output variables from the GHB and GHK electrolysis systems. The research results show that the integrated PV-GHB system produces a larger hydrogen gas flow rate and higher system performance efficiency compared to PV-GHK.

Abstract

Raindrops hitting the roof material and the falling rainwater exerting pressure on the roof can be utilized as a power source with piezoelectrics as a converter of mechanical energy into electrical energy. The purpose of this research is to find the right roof material to produce maximum electrical power and efficiency in harvesting the energy of falling rainwater. This research method is carried out by comparing three types of roof materials placed on top of the piezoelectric. The falling rainwater will press the roof material and piezoelectric, thus producing electricity in the form of voltage and current measured with a multitester. The measurement data is processed into electrical power and efficiency. The results of the study found that the type of roof material affects the performance of the piezoelectric as an energy converter.
