Pengendalian kecepatan putar motor BLDC perlu dilakukan karena motor ini banyak dipakai di berbagai industri dan harus memiliki kecepatan tertentu pada masing-masing aplikasinya. Ada banyak metode kontrol kecepatan putar motor BLDC, salah satunya yang populer adalah kontrol PI biasa. Kontrol PI biasa terbukti mampu menunjukkan kinerja yang baik pada pengendalian plant. Tetapi setiap terjadi gangguan pada plant seperti gangguan tegangan pada input elektronika sistem maupun gangguan eksternal yang berpengaruh pada kecepatan seperti hambatan gesek yang berubah-ubah yang membuat sistem tidak linear, kontrol PI biasa berkurang sensitivitasnya. Pada penelitian ini dilakukan identifikasi sebagai estimasi model matematika sistem motor BLDC dengan cara pengukuran dan penyimpanan data tegangan input dan kecepatan output pada sistem motor BLDC untuk mendapatkan fungsi alih (transfer function) yang digunakan dalam perancangan kontrol dan simulasi. Perancangan kontrol dan Simulasi menggunakan MATLAB untuk menawarkan dan membandingkan alternatif lain dari kontrol PI biasa yaitu dengan menggunakan kontrol supervisory fuzzy-IP. Hasil simulasi menunjukkan bahwa: (1) kontrol supervisory fuzzy-IP lebih responsif daripada kontrol PI biasa dengan rise time dan settling time sebesar 0,6144 milidetik dan 1,0780 milidetik saat diuji tanpa gangguan dan sebesar 0,5353 milidetik dan 0,9066 milidetik saat diuji dengan gangguan, (2) kontrol supervisory fuzzy-IP mampu mengungguli kontrol PI biasa dalam hal kestabilan yang bisa dilihat pada kontrol supervisory fuzzy-IP dengan parameter overshoot,RMSE dan MSE masing-masing bernilai 0%, 15,8044, 249,7796 saat diuji tanpa gangguan serta bernilai 3,9410%, 19,8381, dan 393,5485 saat diuji dengan gangguan dan (3) kontrol PI biasa dan supervisory fuzzy-IP ini sama-sama mampu menghilangkan steady state error pada sistem motor BLDC ini.

This paper presents a comparative study in terms of power quality and fuel consumption in electricity generation using three kinds of fuel: gasoline, liquefied petroleum gas (LPG) and biogas from anaerobic digestion of municipal solid waste. The electrical parameters measured and compared are voltage, current, frequency, active power, apparent power, reactive power, power factor, displacement power factor, current harmonics, voltage harmonics, transient, sags and swell. From the experiment, resistive loads (100 W bulb and 2 x 100 W bulbs) and resistive-inductive load (125 W water pump) were used as loads of generator set. It can be seen that in general, the power quality among those three fuels shows almost the similar performance. The problem on using combustible gases, either LPG or biogas, significantly appears at the frequency with greatly difference to the standard (i.e. 50 Hz).DOI:http://dx.doi.org/10.11591/ijece.v3i6.3942

This paper describes a study that gives a consideration to change fuel source for electriccity generator from gasoline to combustible gas. A gaseous fuel conversion technology is presented and its performance is compared with gasoline. In the experiment, two types of load were tested, resistive and resistive-inductive. By using both fuels mostly the power factor (Cos φ) of resistive-inductive load variations were greater than 0.8, and they had slight difference on operational voltage. The drawback of using gaseous fuel is the frequency of the electricity might be not reach the standard frequency (i.e. 50 Hz). In the lab scale experiment, the gasoline consumption increased proportionally with the load increase, while using gaseous fuel the consumption of gas equal also increased where the average consumption value is 100 gram per 15 minutes operation for the tested load in the experiment. The main advantage using gaseous fuel (liquefied petroleum gas or biogas) compared to gasoline is a cleaner emitted gas after combustion.

Lighting generally consumed 25%-50% of total electricity consumption in a building. Nowadays, the building lighting source is dominated by the use of fluorescent lamps. The previous technical papers by other researchers had focused on power density control of incandescent lamps, which is now rarely used, unconsidered national standard as control reference value, and required a high-cost in investment. By these reasons, this paper proposes a building lighting system based on fuzzy logic scheme to automate fluorescent lamps in order to achieve illumination according to Indonesian National Standard (SNI). The input variables were indoor lighting, inference from outdoor lighting, and occupancy. The output variable was the required illumination to achieve the standard. The required illumination determined the number of lamps that had to be turned on. In the experiment result, a classroom illumination of lighting without controller in workdays was about 350 lux, while with the proposed controller it varied between 250–300 lux close to the SNI, i.e. 250 lux. Meanwhile, with the proposed controller the electricity consumption for a classroom was 75% lower than the lighting without controller.

Bio-energy from biogas can be produced through anaerobic digestion of either organic solid waste or wastewater. Energy production process in the digester is however sometimes hard to be monitored due to manual measurement, otherwise it needs a high technology requiring a high cost budget. This paper presents a low cost technology to monitor the process by using Android based smart phones which can easily be integrated in human daily activity. A program was built by using Eclipse in order to give send/receive command to/from the hardware and display the measurement data on the registered smart phones. The measurement controller was put at the anaerobic digester to record temperature and Relative Humidity (RH) data to memory card and to transmit the data to smart phones. In the experiment with 20 data samples, mean errors were repectively -0.317 oC, 0.932 oC, and 1,378 % for temperature sensor LM35, and temperature and RH sensor using SHT11. Mean squared error for LM35 was 0.373 oC and for SHT11 was 1.117 oC and 2.629 % for temperature and RH respectively. The system has been also implemented in the real anaerobic digester. Electrical energy consumption was 0.623 Wh with 30 minutes cycle time and one minute sampling time.

This paper proposes a non-destructive technology to control subterranean termites Coptotermes curvignathus Holmgren infestations. In the experiment, the apparatus for termites control used electromagnetic waves at two frequencies: 300 Hz and 300 kHz. Termites were exposure to electromagnetic waves on direct methods with variation of exposure time 15, 30, 45 and 60 min respectively. The use of electromagnetic waves for termites control are very beneficial, they are odorless, noiseless, friendly to environment, and easy to apply. The result showed that electromagnetic waves had an effect to termites. The value of termites mortality was range between 25.45~82.27% and the average value of termites filter paper consumption was between 8.89~39.44%. Meanwhile on control treatment, termites mortality and termites filter paper consumption were respectively 14.05% and 79.88% in average. The highest frequency of electromagnetic waves and the longest irradiation time caused the highest average value of termites mortality. The magnitude field from apparatus was range between 0.069~0.1815 μT, which is safe to utilize around the human body. The best result was achieved on frequency 300 kHz and irradiation time 60 min. These results represent important information about the potential use of electromagnetic waves technology for termites control as an environmentally benign alternative in spite of the insecticides uses.

This paper proposes a new control design approach for industrial wastewater treatment where its logic control is verifiable. In this research, a treatment control design in a lab-scale was controlled by a microcontroller circuit. The developed system combined anaerobic digestion, aeration and filtration process. Its logic control algorithm was designed by using Signal Interpreted Petri Net. In the logic verification, six analysis properties were satisfied: conflict free (logical process had no conflict behavior), termination (the process could be terminated from any state), non-contradictory outputs, live (any process state could always be reached from other state), deadlock-free, and reversible (the process could always back to initial condition). In the design evaluation, the average value of transparency metrics was 0.984 close to 1 as the best value. The system performance was evaluated by pollutant removal efficiency. The highest removal efficiencies were obtained when each anaerobic and aeration treatment were performed for three days respectively and followed by filtration. Within this condition, the system obtained average removal efficiency 91.7% of Chemical Oxygen Demand and 95.4% of Total Suspended Solids. In terms of electricity consumption, the system needed only 1,857.6 Watt-hour for a batch treatment process.

Paper ini menggambarkan tentang pengembangan electronic load controller (ELC) yang dilengkapi dengan sistem pemantau parameter kelistrikan untuk generator sinkron pada pembangkit listrik tenaga arus sungai (PLTAS). Di sini generator sinkron dapat menghasilkan frekuensi dan tegangan yang konstan jika beban listrik dan debit air terjaga konstan. Pada kondisi daya yang dibangkitkan lebih besar dari beban konsumen, ELC menjaga frekuensi dan tegangan konstan dengan menambahkan beban penyeimbang. ELC yang dikembangkan ini terdiri dari zero crossing detector, microcontroller atmega32, beban penyeimbang (ballast load) dan rangkaian pemicu TRIAC. Sistem pemantau melengkapi ELC sebagai alat bantu dalam melihat karakteristik parameter pembangkit dan pola konsumsi beban, serta mempermudah dalam troubleshooting. Sistem pemantau ini terdiri dari sensor arus non invasive SCT 013 005, real time clock (RTC), rangkaian pengkondisi sinyal, sensor tegangan, lcd display, module sd card dan microcontroller atmega32. Saat ini sistem sudah dioperasikan selama lima bulan di PLTAS Nanga Manjang Kabupaten Sekadau Provinsi Kalimantan Barat. Dari data dalam tiga hari yang tercatat pada sd card menunjukkan, bila arus pada beban pengguna rendah, maka arus pada beban penyeimbang meningkat, sehingga tegangan yang dihasilkan konstan dan frekuensi tidak melebihi dari 50,5 Hz.

In the current electric energy supply crisis, Indonesian Government encourages the citizen to save electric energy. Therefore, we should control the electric power consumption in the offices or houses intelligently. Using one of automation technologies, Programmable Logic Controller (PLC), we can control electricity usage in our surroundings. This research focuses on the development of Automatic Transfer Switch (ATS) system to become Automatic Transfer and Synchonization Switch (ATSS). The system can monitor electric power consumption connected to PLN. If the electric power consumption has reached > 80%, then the generator as electric energy back up supply will support in a synchronized way. If electric power load is < 80% then automatically the generator is non-active. ATSS can become an ATS as well. It is an electric energy back up power supply when supply from PLN is cut. The result shows that a 900 watt electric power PLN, with 1.060 watt maximum load, and 300 watt support generator synchonization, can support a load of 1.450 watt.
