Abstract

One method  for energy transfer wireless is magnetic induction couplings. In general, copper is the most important element in producing magnetic flux in the form of coils or coils. Copper is used as an electrical transfer media because the material consists of many electrons that can move freely. Magnetic coupling simulation with Multisim 12.00 shows that the transmitter coil induces a receiver coil and energy transfer occurs.

Abstract

The problem in this study is to design the filling control of Calcium Carbonate CaCO3 using a microcontroller-based ultrasonic sensor and how to control charging Calcium Carbonate CaCO3 using an ultrasonic sensor based on a microcontroller. The purpose of this research is to find out the making of tools and work methods for filling Calcium Carbonate CaCO3 using an ultrasonic based microcontroller. In this study using qualitative research methods using data analysis in the field, the experiments with Ultrasonic Sensors HC-SR04, the working principle for detecting Calcium Carbonate CaCO3 with microcontrollers ATMEGA328. Components used: microcontroller, servo motor, LED, LCD, Photodioda. The results of this research test to find out how efficient, so that the filling control device of Calcium Carbonate CaCO3 with the HC-SR04 ultrasonic sensor can run well, testing is done with miniature trucks entering the filling area then ultrasonic sensors that have a value of 5 cm, the servo motor will opening the valve indicates charging is running. If filling in Calcium Carbonate CaCO3 which enters the truck is 50% volume, and Calcium Carbonate CaCO3 reaches a 9 cm height threshold from the Ultrasonic Sensor, the servo motor will move to cover the valve and the buzzer will ring indicating full charge.

Abstract

Metode perawatan serta penanganan gangguan pada trafo distribusi 20 kv di PT. PLN (persero) rayon Brondong  digunakan metode power quality atau kualitas daya yang mana dengan menggunakan alat ukur mega ohm meter (megger meter) dan untuk menjaga keandalan daya yaitu dengan menggunakan aplikasi ETAP 12.6.0 untuk mengukur frekwensi tegangan, kesetabilan tegangan, harmonisa tegangan, dan drop tegangan. hasil analisa dalam perawatan trafo distribusi 20 Kv di PT. PLN (persero) Rayon Brondong dengan pengukuran yang telah dianalisa tahanan isolasi dengan Mega Ohm Meter (megger tester) 500/1000 V hanya ada satu trafo yang kumparanya bocor yaitu pada trafo nomor 7 yang ada di tabel dalam 10 sample yang diambil. Dan mengukur keandalan daya dengan menentukan frekwensi sistem dengan menggunakan program ETAP 12.6.0, data kesetabilan tegangan hanya pada feeder Pambon dan Solokuro yang nilai Harmonisnya dan drop tegangan pada PLN Rayon Brondong masih memenuhi standart PLN kecuali feeder pambon dan solokuro. Pada penanganan gangguan dan kerusakan 20 Kv di PT. PLN (persero) Rayon Brondong telah memenuhi kualitas daya (power quality) karena pada penanganan gangguan telah memenuhi Standar Operasional Prosedur PLN. Dan saat kerusakan pada trafo, PT. PLN (persero) Rayon Brondong langsung mengganti dengan trafo yang baru atau diganti dengan trafo mobil (semi permanen) yang di datangkan langsung dari PT. PLN (Persero) distribusi jawa timur area Bojonegoro.
