This study is aimed at determining the piezoelectric configuration for generating electricity from wave power through the design of a prototype model named Cov-TOTal. The study was carried out in Tomini Bay, Lopo Village, Batudaa Pantai District, Gorontalo Regency, located at approximately ±50 meters from the shoreline, while the piezoelectric construction was arranged in parallel with varying numbers of 28, 70, and 90 pieces. The result showed that the amount of piezoelectric configuration affects the value of the voltage and electric current generated by the Cov-TOTal model. Furthermore, the average electric voltage values were 17.58, 20.76, and 29.85 volts, while the average current was 1.16, 1.73, and 2.01 mA for each piezoelectric amount. Therefore, the largest values of power and electrical energy for each piezoelectric are 16.65 mW and 0.56 joules, 31.82 mW and 1.20 joules, and 44.59 mW and 1.77 joules, respectively. This study concluded that the amount of piezoelectric configuration has a significant effect on the voltage, current, power, and electrical energy produced.

Abstract This communication relates to the heating of plastic materials of. a semiconducting nature by passing electricity through them. In particular, it relates to the vulcanization of rubber and rubberlike materials, including Neoprene, with heat generated by the conduction of an electric current and, similarly, it relates to the heat treatment of thermosetting plastics by conduction of an electric current. It is well known that all electrical conductors are heated to some extent by the passage of an electric current. This heating is a direct consequence of internal resistance. The effect so obtained is proportional to the electrical energy absorbed, and is expressed by the equation: power=I2R, in which I is the current in amperes between two points and R is the corresponding resistance in ohms. The unit of power is the watt. Others have used electrical means of heating unvulcanized rubber, but the disclosures differ fundamentally from this proposal. For example, Neerlye coils a steel ribbon and an uncured rubber belt in a spiral and heats the coil by passing electricity through the steel. Newton claims vulcanization by abeam of electrons from a cathode ray tube. The most significant disclosure is by Dufour. This claims the “process for the vulcanization of rubber characterized by the feature that the rubber to be heat-treated is arranged as a dielectric between the electrodes of an electric condenser to which there is applied a high frequency alternating current of a periodicity of several million cycles per second”. This patent is characterized by utilization of high-frequency fields of the order of several megacycles per second. Further, it is not required in induction curing with high-frequency current that the electrodes be in actual mechanical contact with the rubber. Induction curing is facilitated when the material to be heated has both a high power factor and a high dielectric constant, but high electrical conductivity of appreciable amount is not essential to the application of the method.

Electrical energy is a very important requirement for the community, along with the development of the era and technological advances that are urgently needed, the need for electrical energy is very large, while the source of electricity that is currently being used still uses energy derived from fossil fuels. As we know that the source of energy derived from fossils is very limited, therefore other energy sources are sought or we are more familiar with renewable energy, one of which is the energy source that comes from the sun, which is better known as solar cell. The electricity from this solar cell is very dependent on sunlight which must illuminate the solar panels so that solar energy can be converted into electrical energy. The output from these solar panels is in the form of voltage and electric current. Some factors that can affect the amount of output or output voltage of electric current in PLTS is, temperature, shadow, (cloud condition, and surrounding environment), and wind speed. Therefore, the purpose of this research is to find out how much the shadow effect on the output voltage and electric current produced by PLTS. It is expected that this research can increase the knowledge of energy derived from the sun in this case the solar cell and know the effect of the shadow on the output voltage and electric current from solar panels.The results showed that there was a shadow effect on voltage reduction and current strength in the PLTS system, namely the 10% shadow area and 12.44 volt DC solar panel current and 2.54 amperage, 100% area covering the voltage output panel and the current of solar panels 12.10 volt DC and 0.22 amperage. The area of the shadow that covers the solar panel affects the output voltage and the strong current of the battery that is the area of the shadow 10% voltage and strong current battery 12.35 volt DC and 18.54 amper, 100% area cover the output panel voltage and strong current battery 11.90 volt DC and 13.85 amperes The shadow area covering the solar panels influences the output voltage and current strength of the inverter, namely the area of the shadow 10% voltage and 226.4 volt AC inverter current and 0.97 amperage, 100% covering the output voltage panel and 220.2 volt AC and 0.66 amperage current.

We have developed a new wave power generator using flexible piezoelectric device (FPED) which is a hydro-electric ocean energy unit designed to convert renewable energy harnessed from ocean energy into usable electricity. In our previous works, the FPED consisting of piezo-electric polymer film (PVDF) is a way of harvesting electrical energy from the ocean power, e.g. tide, current, wave, breaking wave and vortex. The concept of this study is that the existing coastal and ocean structures (i.e. breakwater, submerged obstacle, reef in shallow water and submerged plate in deep water) are utilized as a wave power generator attached with the FPED to make a safety and disaster prevention. We examined the usefulness and electric performance of the FPED excited by waves in experiments.

One of the urgent tasks of using renewable energy sources is the use of a power unit for converting the energy of sea waves into electrical energy. An important element of the design process of a wave power plant is to carry out mathematical modeling of its operation under various operating conditions to determine the output power and conduct a feasibility study. The process of converting the energy of sea waves into electrical energy for the proposed type of wave power plant is based on forced vertical oscillations of the power unit's float caused by sea waves. The mathematical model of the behavior of the float connected to the generator is based on the integro-differential equation of forced oscillations and makes it possible to determine the dynamics of its oscillations and draw a conclusion about the power taken from the generator connected to the float. The article presents the calculations of the dynamics of the float connected to the generator, the wave equation, the integro-differential equation of the float oscillations, the modeling of the incident wave and the float power unit is carried out. Data on the length, period and height of waves in the Black Sea off the coast of Crimea are used according to official forecasts and observations.
