Abstract

At this time controlling electrical equipment in the form of fans and lights are still mostly using conventional switches. By using an android voice command device with a bluetooth connection, controlling the equipment can be easier. Using a Bluetooth connection will reduce the use of cables and speed up the process of activating or deactivating electronic devices because they do not have to get close to reach the switch. With input in the form of voice commands is very easy in controlling electronic devices such as fans and lights. With the adjustment of the fan speed and brightness of the lights with voice commands can save electricity and more easily in its settings

Abstract

With the increasing number of people contaminated with cat disease, many veterinarians specializing in cats in Indonesia open up a practice in big cities only. Thus, it is not uncommon for cat owners who are late to provide treatment for skin diseases since the initial symptoms occur. Based on the problems to overcome skin diseases in cats, it is necessary to build a computerized system that has knowledge such as veterinarians and the system can be a tool in diagnosing types of diseases and provide solutions for treatment and prevention with the expert system of Certainty Factor (CF), because the Certainty Factor (CF) method is to prove whether a fact is certain or uncertain in the form of a metric that is usually used in expert systems. The results of the system are to help users, among others, veterinarians in diagnosing skin diseases in cats and animal owners, especially cats to find skin diseases in cats. It is expected to make it easier for doctors and cat owners to determine the type of skin disease based on existing symptoms and get the right treatment method.

Abstract

In a developing country, the rate of electricity demand is increasing along with the increasing rate of population growth and the rate of economic development of the country. With the growing development of the use of electronic technology in power systems, more and more non-linear equipment is used in the industry. This non-linear equipment can affect power quality because this non-linear load is the primary source of harmonic interference. To minimize the impact of the harmonic generation that occurs on non-linear loads such as induction motors, harmonic filter equipment is needed. This study also compared the current and voltage THD levels based on the IEEE standard and performed calculations to design a single tuned passive filter. This calculation is done because of the emergence of harmonics on a 3-phase induction motor that has exceeded the standard limit, so it must reduce the harmonics. Moreover, disturbances that occur, such as torsion vibrations caused by the interaction of the fundamental harmonic magnetic field, causing higher noise. Furthermore, it leads to additional thermal stress on electric motors, which have an impact on reducing the life of motor insulation. Based on the comparison and analysis obtained that the measured current THD still exceeds the IEEE standard limits. Then the interference that arises in the 3-phase RAW MILL induction motor will have an adverse impact if not handled correctly and adequately.
