Abstrak. Sistem kendali otomatismenjadi sangat penting saat ini. Teknologi instrumentasi yang berkembang sangat pesat menjadikan sistem kendali otomatis berkembang pesat. Dengan adanya sistem kendali otomatis ditemukan pula gangguan yang memengaruhi sistem, seperti Noise atau sinyal gangguan. Berbagai metode kendali banyak digunakan salah satunya adalah Repetitive Control. Kemudian diperlukanlah pengujian analisis untuk memilih sistem kendali mana yang paling baik dalam menghilangkan sinyal gangguan yang memiliki 3 nilai frekuensi dengan menggunakan sistem Plug-in Repetitive Control (RC) yang dilengkapi dengan filter. Pada penelitian ini digunakan metode Least Common Multiple (LCM) dan metode Multi Repetitive Control (MRC). Hasil penelitian menunjukkan bahwa sistem dengan metode MRC memiliki kecepatan menghilangkan sinyal gangguan paling   baik yaitu 1.8s.Abstract. Automatic control system becomes very important today. The fast growing technology of instrumentation makes the automatic control system grow rapidly. With the existence of automatic control system there is found disturbances that affect the system, such as noise or disturbance signal. Various control methods are widely used, one of them is Repetitive Control. Analytical testing is then needed to choose which control system is best for rejecting disturbance signals that have 3 frequency values using a Plug-in Repetitive Control (RC), using filtered system. This research used Least Common Multiple (LCM) method and Multi Repetitive Control (MRC) method. The results showed that the system with MRC method is slightly faster and best in rejecting disturbance signals with rejecting time 1.8s.

Abstract

DC high voltage amplifier is one of the important components to support of PVDF thin films polling equipment. Hardware polling is a very important tool in the characterization of PVDF thin films to increase piezoelectric properties. The existence of the problem will be difficult to obtain a high voltage DC sources of lead in the market encouraged us to design and create high-voltage DC source. In research that has been done I've been able to design and create high-voltage amplifier 30 KV DC as a producer of high electric field. To validate the performance of this high voltage DC amplifier has created further testing and measuring the output voltage. Testing is performed to determine the precision, accuracy and stability of the output voltage of the amplifier for more than 60 minutes. From the test results and output measurements performed show that the relative error of 4.5%. Tool output stability is good enough for a span of 30 minutes. This indicates that the design and manufacture of high DC voltage gain have been successful.   Keywords: DC Amplifier, Electric field, High voltage, Polling, PVDF Film

Abstract

This paper reports the results of a study relating to the synthesis of a novel ternary CoFe2O4/CuO/CoFe2O4 thin film as a giant magnetoresistance (GMR) sensor. The CoFe2O4/CuO/CoFe2O4 thin film was prepared onto silicon substrate via DC magnetron sputtering with the targets facing each other. X-ray diffraction was used to determine the structure of the thin film and a 4-point method was used to measure the MR ratio. The GMR ratio is highly dependent on the ferrimagnetic (CoFe2O4) and nonmagnetic (CuO) layer thickness. The maximum GMR ratio at room temperature obtained in the CoFe2O4/CuO/CoFe2O4 thin film was 70% when the CoFe2O4 and the CuO layer had a thickness of 62.5 nm and 14.4 nm respectively.

Abstract

In this paper we will present the results of the study at the application of Polyvinylidene Fluoride (PVDF) sensors to determine the value of angular shift. In the study carried out the loading on the PVDF sensor so that the PVDF film on the sensor changes in the form of angular shift. For every angle shift that occurs then the sensor will detect in the form of output current on the display. The sensor loading is done for the angle change ranges from 100 to 800. From the research results show that the sensor output shows a mathematical relationship between the magnitude of the angular shift with the resulting current. The mathematical relationship is expressed in terms of exponential equations. This clearly indicates that this PVDF sensor can work well in detecting large angular changes.

Abstract

A lack of method to find out the fairness limit of fuel consumption in mining operations enables statistical approach with two-tail test be applied to observe the fairness limit of actual fuel oil consumption compared to the manual handbook of its equipment. Fuel consumption according to the manual handbook for EXCA LIEBHERR 9350 excavator is 207.23 liters/hour and EXCA HITACHI 2500 is 191.51 liters/hour, while CATERPILLAR 777D Dump Truck is 36-53 liters/hour consider as low, 53-73, 8 liters/hour medium, and 73.8-96.5 liters/hour as high. This statistical approach has been carried out after fulfilling the concept of mechanized earth-moving. As a result, the differences in fuel consumption of LIEBHERR 9350 and HITACHI 2500 are 3.72% and 3.26%, which are still in range of a reasonable fuel consumption limit, while CAT 777D operating on LIEBHERR 9350 and CAT 777D operating on HITACHI 2500, each shows a difference in fuel consumption. The differences are 29.65%, meaning that it has exceeded the reasonable limits of fuel consumption and 7.15%, meaning that it is still in range of a reasonable fuel consumption limit.
