Abstract

The electric motor is one of the technological developments which can support the production process. Not only in the manufacturing, but also in the transportation sector. The AC motor is divided into the synchronous and asynchronous motor. One type of asynchronous motor which widely used is the induction motor. In this study, the application of the IFOC control method and the LQG speed control method will be used to control the speed of an induction motor. The PID algorithm is also used as a comparison. Tests were carried out using MATLAB software. The speed variation and load variation are tested to validate the controller performance. PID is superior in terms of settling time and IAE. On the other hand, LQG is better in energy consumption. In terms of IAE, LQG has a higher value compared to PID by up to 56.67%. On the other hand, LQG is superior in terms of energy, which is 8.38% more efficient.

Abstract

Saat ini listrik menjadi kebutuhan utama masyarakat. Pembangkit listrik di Indonesia sebagain besar bersumber dari energi batu bara yakni mencapai 57.2%. Batu bara sendiri merupakan sumber energi yang tidak bisa diperbaruhi. Selain itu, pembangkit listrik jenis ini menimbulkan pencemaran udara. Untuk itu, sumber pembangkit listrik alternatif yang ramah lingkungan dan dengan suplay yang melimpah sangat diperlukan. Salah satu sumber listrik alternatif yang paling mudah untuk dibangun dengan biaya rendah adalah sistem panel surya. Sistem panel surya sudah banyak diaplikasikan di Indonesia, bahkan sudah dibangun Pembangkit Listrik Tenaga Surya (PLTS). Beberapa tempat yang sudah terpasang sistem panel surya, pada akhirnya terbengkalai karena rusak dan masyarakat belum begitu faham sistem panel surya sehingga tidak bisa memperbaikinya. Untuk itu, sosialisasi tentang energi terbarukan ini penting untuk dilaksanakan. Pengenalan sumber energi terbarukan tenaga surya ini perlu dikenalkan lebih dini kepada siswa sekolah untuk meningkatkan minat dan rasa ingin tahu siswa dalam mempelajari, memanfaatkan, dan bahkan mengembangkan nantinya. Kegiatan dilakukan secara daring guna mematuhi protokol kesehatan covid-19. Media yang dipakai adalah grup whatsapp, video, dan e-booklet. Untuk mengukur keberhasilan program, sebelum acara dilakukan pre-test dengan hasil 22, 5% siswa tidak tahu tentang panel surya. Setalah sosialisasi post-test, hasilnya rata-rata nilai mencapai 79,46%, yang menunjukkan tingkat pamahaman peserta cukup baik terhadap materi yang disampaikan. Sampel pertanyaan mendasar tentang sistem panel surya, menunjukkan hanya 0,9% siswa yang salah. Kesimpulan akhir, siswa telah mendapat pengetahuan tentang energi terbarukan panel surya melalui kegiatan sosialisasi yang telah dilakukan.

Abstract

The corona pandemic has caused global problems, including Indonesia. One way to reduce the spread of the coronavirus is to wash your hands frequently with soap or hand sanitizer. Many types of hand sanitizers were developed to support efforts to prevent the spread of the corona. For this reason, this paper proposes two types of Contactless Hans Sanitizer (CHS) prototypes. Function tests and user satisfaction tests were carried out to determine the performance of the CHS. The test results show that type A CHS which only works fully electrically is more reliable than type B which works with electrical and mechanical systems. Of the 10 respondents, 90% chose CHS type A.

Abstract

DC generator with variable rotation will produce uncontrolled voltage, causing problems in its utilization. In this study, it is proposed to develop a voltage control on the generator, in order to produce a fairly controllable and reliable voltage, with an analog circuit using a multistage comparator. Control of the generator output voltage is carried out by adjusting the field current from a separate voltage source which is forwarded to the resistance which is regulated based on the generator output voltage level with a multilevel comparison system. The results obtained are the output voltage ranges from 26 to 30 Volts and the output current ranges from 3 to 20 Amperes. This provides operational safety for the generator and battery. This technology can be used in dc generator systems in automotive engines, windmills, and other power plants.

Abstract

One technology to support production speed is electric motors with high performance, efficiency, dynamic speed and good speed responses. DC motors are one type of electric motor which is used in the industry. Sliding Mode Control (SMC) is the robust non-linear control. The basic theory regarding SMC is presented. The SMC design which is implemented is the speed control of the DC motor is analyzed. The controller is implemented in simulation using MATLAB / Simulink environment. The step response and signal tracking test unit are carried out. The results show that SMC has a better performance compare to PID which is faster settling time and no overshoot and undershoot.

Abstract

Variable voltage DC power supply that has wide range of power, lightweight and inexpensive is quite difficult to obtain. This research designs and tests a DC power supply without a transformer using switching technology that utilizes TRIAC. The 220 Volt AC power source is converted to DC electricity by the method of cutting off some AC waves signal, using TRIAC, and then rectifying it with diodes and filters. DIAC functions as a trigger TRIAC at the specified time, by turning the variable resistor. The test results show that the output DC power voltage can be adjusted from 5 Volts to 75 Volts by adjusting the DIAC resistance and the load resistance. The results of the series image characteristics are given 2-dimensional and 3-dimensional graphics.

Abstract

Across the year, the needs of Indonesians in the use of electronic equipment are increasing, which results in higher electricity usage. Because most of the electricity load uses AC power, in the application of a DC power source such as solar cells, an inverter that converts DC to AC power is needed. Therefore, the inverter is one of the tools that are widely developed in power electronics. The output voltage from simulation and real hardware is a sine wave with some distortion due to lack of filter; therefore, there occurs a harmonic. The voltage and frequency were also measured with a multimeter. The result shows that both voltage and frequency are closed to the design specification which is 220V 50Hz with the voltage and frequency difference of 1.09% and 0.4%, respectively.

Abstract

The limitation of the operational area of the PWM signal generator provided by the microprocessor or chip, give the opportunity to develop flip flop technology that has been widely used in digital technology as a latch, counter, register, memory and so on, will  be able to be developed into a PWM driver. Flip flop technology has developed and is able to reach a very wide operational area regarding voltage and frequency variations. So in this research flip flop technology was developed as a PWM signal driver and the results were better, involving the ability to vary voltage from 6 to 60 Volts, frequencies from 2 to 81 kHz and duty cycles of 10 -75%. Furthermore, if a component with higher capability is selected, it will be able to operate in very low to very high operating areas, exceeding the capabilities of the microprocessor or chip.
