Abstract

The hybrid technology here is a combination of technology derived from solar energy and biogas from cow dung. Each cow shed has a roof that can be installed with solar cells to generate electricity, and cow dung can be used as a source of biogas energy, which can also be converted into electrical energy. This hybrid technology is one of the new renewable energy potentials in an environmentally friendly future.

Abstract

Pemulutan village has a location that is separated by a small river, where only one of its locations has access to PLN electricity rom the government. The portable hybrid on grid system PV-PLN-Generator has the ability to combine a power source from PLN with alternative sources of electricity from solar panels and generators, this system was applied in this study by adding a portable system, so that it can be carried and moved easily from opposite locations of river. The ouput power of one solar panel is about 20-25 W, so it takes 6-7 solar panels to be used with load 70 Watt for 12 hours. The results of this research are very helpful for Pemulutan’s village, with the portable hybrid on grid (PHoG) system can help access electricity for lighting, process garden products, and relieve the cost of charging PLN electricity.

Abstract

Gas condensation is one of the problems in the liquid smoke production process. Uncondensed gas will have an impact on the liquid smoke produced and air pollution. Here, several methods are applied to determine the percentage level of liquid smoke produced by the gas condensation process. The condensation method uses conventional normal water, gas condensation using cold water, and gas condensation using cold air. The raw materials used are oil palm shells with a size of -4+5 mesh, a pyrolysis temperature of 300-4000C, and a liquid smoke production process for 300 minutes. Based on the test results, gas condensation occurs optimally in the cold air method, with the results of 22% liquid smoke, 64% charcoal, and 14% non-condensed gas. Compared with the condensation of the standard water method, the condensation method of cold air is superior to 36.36% for liquid smoke to minimize air pollution by up to 48%. The results of this study indicate that temperature and fluid effect the effectiveness of the gas condensation process, thereby increasing the yield of liquid smoke and reducing air pollution during the liquid smoke production process.

Abstract

In the world and Indonesia, coal is one of the primary fuel sources for steam power plants (PLTU). This is due to the shrinking and increasing prices of fuel oil. With the abundance of coal energy sources, it continues to be used as the primary energy source for power plants in Indonesia. The economic efficiency obtained can reach 80% compared to the use of solar. However, Fly ash and Bottom ash (FABA), or solid waste produced from the coal combustion process at the PLTU, contains many inorganic minerals, which can pollute the environment, such as air and soil pollution. Conventionally, regarding economic law, Construction and Demolition (C and D) in the circulation system between materials and products must have zero material value and no longer produce residual waste in final disposal. This research implements Circular Economy (CE) to minimize the negative impact of FABA on the environment at PLTU. The experiment used FABA Coal as a mixed material to make Hollow Blocks with six combinations of sizes. The results obtained, the greater the percentage of FABA used, can minimize production costs and improve the quality of hollow blocks. From an economic cost analysis, using FABA for mixed materials for open block production will provide 55% greater economic benefits and 34.67% higher quality Hollow blocks compared to the composition of materials without FABA mixture.

Abstract

The Heat Recovery Steam Generator (HRSG) is a combination of a Gas Power Plant (PLTG) and a Steam Power Plant (PLTU), this plant utilizes exhaust gas from the PLTG to produce steam as the working fluid in the PLTU. The residual heat from the heating process at the HRSG is channeled into the chimney, and the remaining heat from the exhaust gas can be converted into electrical energy with the Thermoelectric Generator (TEG) module. This research was carried out by installing the TEG module in series on the surface of the HRSG chimney wall, using laboratory scale measurements. The heat source uses a heater with a total power of 2,000 W. The research results show that the TEG module can convert the residual heat energy of the exhaust gas from the HRSG chimney into electrical energy. Four TEG modules mounted on the chimney surface can generate a voltage of 0.83 V and a maximum power of 2.79 mW. These results indicate that the TEG module is an opportunity to convert heat energy into electrical energy for further development.

Abstract

Hydrogen is almost ideal fuel in reducing emissions without CO, CO2, SOX or NOX. Hydrogen can be used through the combustion or Fuel Cell processes so that emissions are low. One of the hydrogen production processes is through electrolysis, both Chlor-Alkali (CA) and Alkaline Water Electrolysis (AWE). Both processes contained a NaOH solution in the CA and catalyst results in AWE. In this test, a combination of CA and AWE processes will be carried out in the fluid circulation at the cathode of two processes. From this study it was found that there was an increase of 11 percent by weight of gas when CA and AWE cathode fluid were circulated in parallel compared to the CA and AWE processes respectively.
