Abstract

Background of this study is an effort to know which technique is suitable to use in teaching speaking. Teaching a foreign language is considered to be one of the most challenging teaching practices. In Indonesia, students are usually afraid of joining foreign language classes. They may feel unmotivated and discouraged easily. Their mindsets say foreign language is difficult to learn because most of them know nothing from the start. Usually, students know nothing how to express what they want to say. Students who have learned English for several years have not been can communicate used English. So the researcher thought that there should be a solution to cope with that problem. The researcher tried to use describing picture as a method to improve students’ speaking skill especially in descriptive text

Abstract

Electric power quality problems include line losses, voltage drops, and the amount of inductive reactive power consumed at load so the power factor is low. Power factor improvement in Politeknik Penerbangan Surabaya electrical system to 0,99 is expected to improve electric power quality by installing a setcapacitorsitor called Capacitor Banks that supply capacitive reactive power. Another benefit is that reduces the load on transformer Poltekbang Surabaya which is now approaching full load. To be able to repair the electric power supply is necessary to measure and calculate the inductive reactive power which can be compensated with witcapacitiveie reactive power by Capacitor Bank. After calculating the capacitor bank value, the location of the capacitor bank installation is then determined so that power improvements can be carried out effectively, The result shows that the compensation needed to improve the power factor on Poltekbang Surabaya is 300 kVAR divided into 5steps, each step requires a 50 kVAR capacitor

Abstract

To meet the needs of small or large scale electricity supply, the use of electrical energy generally uses 1 phase electricity and 3 phase electricity which is used to operate electrical equipment. To be able to find out the voltage, current, and electrical power of the low-voltage distribution network, manual checks are carried out on each R, S, T phase which is on the low-voltage distribution panel. When a 3-phase power failure occurs, it is often difficult to identify which phase is failingSo that in this case it is considered less efficient, for this research is expected to overcome the problems that have been identified. So a tool is made that can monitor failures in the R, S, and T phases which functions as safety when a failure occurs and can display a notification in which phase a failure occurs.In this study, the PZEM-004T sensor, Wemos D1 mini-module, and Android Studio are used which can allow for remote monitoring using electronic devices that have installed applications that have been created. when an error occurs, the "reset" button on the monitoring application is used to reset the protection to restore the device. The current difference in the avometer is 1.48A and the sensor is 1.46A and the current flowing to the load is written 1.88A. The contactor works when the relay receives a command from the Arduino nano with a fast time: 1.60 seconds on the first try, 1.72 seconds on the second experiment, and 1.68 seconds on the third experiment.

Abstract

630 kVA, 20 kV/400 Volt transformer is a distribution transformer that supplies electrical loads at the Aviation Polytechnic of Surabaya. In a distribution transformer if the inter phase load is unbalanced there will be a neutral current flowing in the neutral wire.  This load imbalance is caused by single-phase loads on a 220 Volt low voltage network. The current flowing in the neutral of this transformer causes losses, namely due to the presence of neutral current in the neutral conductor of the transformer and losses due to neutral current flowing to the ground. After analyzing the peak load during the day of 79.92% and load imbalance during the day of 12.23%, then there is a neutral current of 181 Amperes and losses due to neutral currents flowing to the ground of 7, 26%, and transformer efficiency  at the day of 88.5 %.
