Abstract

Polishing have played an important role in the preparation of metallography testing. Poor polishing produce in an unflat and rough surface of the material, resulting an unclear metallography image that is difficult to identified. In general, the material commonly used for polishing is alumina paste. Alumina paste is expensive and takes a few minutes to produce a smooth and flat surface. In this research, polishing was done by using several metal polisher other than alumina paste, these were magic***, auto***, bras**, ki*, menze*** and pri** which are sold cheaply at supermarkets or online stores. Analysis was carried out on the surface of the polishing by these materials and the etching surface. The test results showed that the material that is polished with magic *** has the smoothest surface or has the least residual scratches compared to other materials even compared to alumina paste, but has the disadvantage of corrosion forming on some parts of the surface. The best polishing time was obtained on polishing for 3 minutes

Abstract

Biogas plant needs to be given specific amount of relative humidity setting in order to make it work optimally. It is one major factors of gas waste adsorption through final process of activated carbon in biogas plant, especially for hydrogen sulfide. Hydrogen sulfide is a side gas appeared in biogas plant which has to be removed by various processes, including the presence of activated carbon filter that usually appeared on last stage of biomass filtration process which is poisonous and corrosive to the metal parts. Today, air humidity gauges have been found quite a lot on the market. However, how accurate the device is, needs to be further proven in the laboratory, especially when the gauges have to face corrosive gases such as this H2S. Therefore, calibration for cheap and efficient relative humidity measurement is very necessary. The method will use comparison between RH reading and RH calculation based on parameters of plant settings in the form of gas composition mixture, flow duration, pressure, volumetric flow rate, and temperature. This paper will discuss how to calculate and measure calibration for relative humidity that is practical, simple and does not cost much so that it is expected to be used for low-funding research in biogas plant.

Abstract

The development of the utilization of solar panels in the future will continue to increase. One characteristic form of solar panels is the I-V curve which can be used to analyze the amount of solar panel output power. By knowing the I-V curve, we can get Maximum Power Point Estimation (MPPE) value that can be supported by solar panels. Information about the estimated value of the maximum solar panel power is an important part in determining the loading capacity, while maintaining the life of the equipment used. Feed Forward Neural Network with Back Propagation Algorithm (FFBP) has proven to be able to provide MPPE value information on solar panel output. The input values ​​in ANN are the voltage and current of the solar panel, while the output of ANN is in the form of an estimated power value. MPPE simulation results obtained an average error of 0.04 points between actual power (MPP) and estimated power (MPPE).

Abstract

The battery is an important component in the context of implementing renewable energy. The type of battery that has a density in energy storage is lithium polymer. The parameter in the battery that must be considered is the State of Charge (SOC) estimation. In general, the SOC battery estimation uses the coloumb counting method because the difficulty level is low. However, there are weaknesses in the dependence on the utility of the current sensor which is used as an accumulation of the integral of the incoming and outgoing currents over time. In this study presents Back Propagation Neural Network (BPNN) as an algorithm for estimating SOC based on OCV-SOC characteristic curves. The OCV-SOC characteristic curve of the battery is obtained from the battery pulse test. Battery voltage, current and discharging time are used as the first BPNN input layer for the estimation of Open Circuit Voltage (OCV). OCV will be learned as the second BPNN input layer for estimating battery SOC. The results of SOC estimation simulations obtained an average error of 0.479% against the real SOC based on the characteristic curve of OCV - SOC.

Abstract

In 2007, Indonesian government applied a program called as “Zero Kero” as an effort to save the government budget in terms of providing subsidies and as a step to diversify energy supplies to reduce the country's dependence on petroleum. It basically convert the fuel used for household cooking from kerosene to liquefied petroleum gas (LPG) sourced from natural gas. In the other hand, Indonesia produces 66-67 million waste in 2019 with organic waste reached 60%.Most of this waste is thrown away in landfill and left abandoned. Meanwhile, organic waste can actually be reprocessed, one of them as a main source of biogas plant. The gas then will be filtered, compressed and liquefied as a replacement of LPG. This paper will conduct a feasibility study of biogas bottling from organic waste in Indonesia.
