Abstract

this paper describes the design of full bridge DC to DC converter 3 phase six legs for solar PV. The prototype is built with 5 kHz transformers, 2 lead-acid batteries with each energy storage of 12V, 7.2Ah and 20WP solar PV. Three phase switching is provided by analog op-amp comparator circuit with variable frequency 1 kHz-20 kHz. The controller of the converter use adjustable DC power supply as voltage reference for analog op-amp comparator, works varies from 0-11VDC (0%-50% duty cycle) and controlled manually

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

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.

Abstract

The power and work trainer kit is used as one of the learning media in thermodynamics practicum. This device focuses on measuring power, work and kinetic energy. This trainer kit uses time measurement in units of second, measurement of object mass using a load cell sensor in grams, time measurement using a timer via Arduino with units of time in seconds, and measurement of distance length in centimeters. Those measurement are needed to calculate work, power, and energy. At this stage, readings will be made on the weight of the object, the distance, and the time required for the test. The data that has been obtained will be compared with the results of calculations on visual basic software. The results of the tests carried out will show that the instrument can work well.
