Abstract

Abstract Two three phase inverters which consists of 12 switches are generally required to control two brushless DC Motors, which are complicated and inefficient to control them. One inverter has 6 switches. This research develops controlling of two brushless DC Motors using nine switch inverters with Pulse Width Modulation method. Nine switch inverter needs PWM for controlling frequency and voltage. Arduino is used to generate PWM in this research. Nine switch inverters are used to convert DC voltage to AC Voltage because of BLDC needs AC Voltage to drive the rotor of motors. In controlling two BLDC Motors, it includes switching control using PWM, to adjust the input frequency which then results in the effect of frequency on the voltage, current, speed of two BLDC Motors and torque. The test of this controller consists of the condition of the motor with and without load. The test results show that the speed of two BLDC motors can be controlled simultaneously with nine switch inverters by adjusting the input frequency. Keywords two brushless DC motors, nine switch inverter, pulse width modulation (PWM), Arduino, Simulink Matlab

Abstract

Abstract The museum is a place to store historical relics that are very important as evidence that these relics are true. Museums are also a means for a country to show the public about the relics of historical objects which are treasures and must be preserved. Lampung Province State Museum, is one of the museums in Indonesia. One of the relics that must be preserved in this museum is the traditional Lampung cloth which is still there and is a legacy for the people of Lampung. The Lampung Museum has a collection of traditional Lampung fabrics whose safety conditions are still a problem for the Lampung Museum management, where there is a lack of care and it is easy for visitors to touch and change the layout of these items. This can cause damage and changes to the collectible. Therefore, the Passive Infra Red (PIR) sensor-based Security System is a tool designed to maintain the security system of the Lampung Province State Museum object "Ruwa Juwai", by using a PIR sensor which can detect the presence of infrared rays which will be detected by the sensor and then will activate the buzzer and LED as output. The design of the PIR sensor-based security system tool is carried out by observing the infrared sensor detected on the PIR sensor and the output on the security system tool in the form of a buzzer and LED.Keywords Lampung Museum, Security System, Passive Infra Red Sensor

Abstract

Abstract Transformer oil is very important because it functions as a coolant and also as an insulator. In transformer oil there are dissolved gases that can cause failure of the transformer due to gas failure (fault gas). This research was conducted to determine the condition of transformer oil by analyzing the results of the Dissolved Gas Analysis (DGA) test. The DGA (Dissolved Gas Analysis) test is used to determine the type of failure in a transformer that has been operating for years. The DGA test is carried out by monitoring fault gases such as H2, CH4, CO, CO2, C2H4, C2H6, C2H2, O2, N2 and O2N2 which generally cannot be detected in testing the characteristics of transformer oil. Based on the test results using the Total Dissolve Gas Analysis (TDCG) method condition 1 with the amount of flammable gas 202.845 ppm with the interpretation that the transformer can operate normally. The test results using the Roger's Ratio method on the Power Transformer 1 GI Kotabumi obtained codes 0 0 0. From the combination of the 3 codes above, it shows that the transformer oil is in good condition. The results of the test using the Key Gas method on Power Transformer 1 GI Kotabumi obtained a CO value of 56 percent caused by overheating of cellulose or overheating of solid insulation in the transformer but that value is still far from the threshold Keywords Dissolved Gas Analysis (DGA),Transformer oil, Roger'r ratio method, KeyGas
