Energy trending lately shown the need of new possible renewable energy. This paper studies about the capability and capacity generating of electricity by using Bio-electricity-Microbial Fuel Cell (Bio-MFC). Bio-MFC is the device that converts chemical energy to electrical energy by using microbes that exist in the sewage water. The energy contained in organic matter can be converted into useful electrical power. MFC can be operated by microbes that transfer electrons from anode to cathode for

Specifically we investigate the relationship between the percentages of organic matter in a sample results in higher electricity production of MFCs power by that sample. As a result, the sewage (wastewater) chosen in the second series experiment because the sewage (wastewater) also produced the highest percentage of organic matter which is around 10%. Due to these, the higher percentage of organic matter corresponds to higher electricity production. The second goal is to determine the condition under which MFC work most efficiently to generating electricity. After get the best result of the combination for the electrode, which is combination of zinc and copper (900mV),the third series of experiments was coducted, that show the independent variable was in the ambient temperature. The reasons of these observations will be explained throughout the paper. The study proved that the electricity production of MFC can be increased by selecting the right condition of sample type, temperature and type of electrode.

This paper illustrates the Artificial Neural Network (ANN) technique to predict the joint torque estimation model for arm rehabilitation device in a clear manner. This device acts as an exoskeleton for people who had failure of their limb. Electromyography (EMG) is the techniques to analyze the presence of electrical activity in musculoskeletal systems. The electrical activity in muscles of disable person is failed to contract the muscle for movements. In order to prevent the muscles from

The EMG signal is collected from Biceps Brachii muscles to estimate the elbow joint torque. A two layer feed-forward network is trained using Back Propagation Neural Network (BPNN). The experimental results show that ANN can well represent EMG-torque relationship for arm rehabilitation device control.

2020 International journal of engineering research and technology  
During the movement control order (MCO), most of the citizen stay at home. Thus, it increased electricity consumption tremendously. The uncontrolled consumption of electricity happened when a lack of awareness among residents to practice home energy efficiency. Due to that reason, this study presents a real case of the MCO electricity energy waste during the early MCO stage. In contrast, sustainable home energy management with 5Core procedures was introduced to overcome the issue. The method

Through the proposed process, energy consumption has significantly reduced while avoiding the spike of the electricity bill during the post-MCO of Pandemic COVID-19. The sustainability of the post MCO for the energy consumption among residential could contribute to the low CO2 emission while securing the factor of the costeffectiveness for the electricity bill. It is hoped that the proposed method will be the guideline for the consumers to manage the consumption of the electricity, where the combination of the human factor will be the advantages.
