Abstract

Community service program is a mandatory activity for higher eduacation in community empowerment and development. These activities include training programs and application of appropriate technology including the utilization of solar energy for water pumps in orphanages in Rokan Hulu regency and the street lighting program in Simpang Petai village, Kampar regency in Riau province. This activity also considers to the obstacles faced by the community with offering and implementing appropriate technology to them as beneficiaries. This activity takes place with the involvement of students in work and lecture program (KKN) that integrated with community service activities.It is shown that the community as beneficiaries have joined diligently and received assistance with this program by implementation of solar water pump and street lighting. The evaluation of this activity shows that collaboration continues between the community and the Department of Electrical Engineering, Faculty of Engineering, University of Riau and the communitis feel helped and there is an improvement in the electricity infrastructure in their village. This activity was carried out in a fostered village by the Faculty of Engineering, University of Riau.

Abstract

Contemporarily, Indonesia and Malaysia are the largest contributors of crude palm oil (CPO) in the world by up to 40%, and 37.3%, respectively. Furthermore, its production value this year reached 19.7 million tons, where each generates 2.5 m3 of wastewater. Meanwhile, of all the provinces in Indonesia specifically, Riau is the largest supplier for exports by up to 38%, generated from 225 palm oil mills, where a total of 6.3 million tons resulting in the generation of about 15.75 million m3 of wastewater, with organic content between the range of 30,000-60,000 mg COD/l. In addition, one of the uses of this wastewater includes anaerobic processes, with the double benefit of reducing COD concentrations, subsequently applying it as fertilizer, and also in the production of methane gas, as an alternative source of energy. The purpose of this study, therefore, is to observe the effect of bioreactor volume, scale-up on the performance of anaerobic hybrid bioreactors, in the treatment of mill effluents. The technology examined in this study was the anaerobic hybrid bioreactor with the dimensions of length 22 m, width 10 m, and depth 1.5 m, and a total volume of 330 m3, which is impermeable to oxygen, and a 250 m3 effective working volume. This was built and operated at a hydraulic retention time of 1 day, in the Palm Oil Mill of Riau, and the results showed the environmental conditions to range from a pH of 7.2 to 8.0, with temperatures from 320C to 350C, acetic acid of 774 mg/l to 1,180 mg/l, and alkalinity of 2,149 mg/l up to 2,400 mg/l. Furthermore, the performance of these reactors are shown by the highest COD removal efficiency of 77.8%, and a biogas test for the propensity of being applied as an alternative energy source obtained a methane gas concentration of 54%. Keywords: anaerobic, bioreactor, biogas, wastewater, performance, palm oil mill effluent

Abstract

Lack of electricity in the rural areas is quite limited to farmers in the lemongrass plantation in Siabu, Salo, Kampar. Their problem provides an idea to assemble solar panels for lighting supplies for lemongrass farmers. The method used for this activity is; field survey, assembly, calibration, and testing. In the test of the battery charging process has been carried out. Batteries charging are utilized 20 Ah and 60 Ah. The solar panels used are 2*50 Wp, Solar Charger Controller, battery, and inverter. The battery of 20 Ah load test results has an electricity of 30 Watt. The maximum battery voltage measured at 12.8 Volt with a load duration of 4 hours. The loading test is also carried out for a battery of 60 Ah has the same load that is a 30 Watt. In this test, the voltage is measured 12.8 Volt, a duration of electricity use for 11 hours.

Abstract

Faktor daya merupakan perbandingan antara daya nyata (P ) dengan daya semu (S). Dalam sistem tenaga listrik, faktor daya sering disebut juga dengan Cos Phi. Faktor daya yang rendah disebabkan oleh banyaknya peralatan listrik yang bersifat induktif. Faktor daya yang rendah ini mengakibatkan besarnya rugi-rugi yang terjadi di sistem kelistrikan akibat besarnya arus yang dibutuhkan untuk daya reaktif. Untuk memperbaiki faktor daya, salah satu upaya yang dapat dilakukan adalah menggunakan bank kapasitor. Untuk memperbaiki faktor daya, maka dalam tulisan ini digunakan metode pensaklaran kapasitor secara otomatis dengan menggunakan smart relay sebagai saklar otomatis dalam menghidupkan dan melepas bank kapasitor. Input smart relay yang digunakan ada dua sensor yaitu pertama berfungsi untuk pengaktifan saklar kapasitor dan yang kedua untuk me-nonaktifkan kapasitor. Tegangan referensi sensor pertama yang digunakan untuk faktor yang rendah sebesar 6 Volt, dan sensor kedua untuk faktor daya yang tinggi sebesar 3 Volt. Pada pembebanan keseluruhan motor induksi diperoleh faktor daya sebesar 0,13, daya aktif sebesar 574 Watt, daya semu sebesar 3.993 VA dan arus sebesar 6,078 A. Setelah penggunaan perbaikan faktor daya menggunakan bank kapasitor diperoleh diperoleh faktor daya sebesar 0,98 dan arus sebesar 0,877 A.

Abstract

This article aimed to design and simulated the speed control of a three-phase induction motor using a PI controller with Space Vector Pulse width modulation technique. The induction motor  used in this article is was designed at the Electrical Energy Conversion Laboratory, Riau University, with a power of 1.1 kW, 380 V, 2-pole. Meanwhile, the PI controller constants used in designing this induction motor were determined using the Fine Tunning method to obtain KP and KI values of 3.539 and 9.526, respectively. The tests were carried out by running simulations in three conditions, namely no load, full load, and variable load at a speed of 2800 rpm. The test results showed that the use of a PI controller can improve the speed response of induction motors by eliminating the steady state error. This is in addition to increasing the rise time response of the motor speed by 0.012s and 0.046s at no load and full load, respectively, when the rise time analysis is at the same value. It can also accelerate the motor to reach a peak speed of 0.247 s and 0.166s at no load and full load. In addition, SPVWM with PI controller can maintain speed setting even though there is a load change during operation, which can be verified with load testing.

Abstract

Steam Power Plant is a widely applied electrical energy generation system.  The limitation of fossil fuels has spurred us to find alternative fuels.  One alternative fuel that can be used in PLTU is biomass.  Coconut coir is a biomass that has the potential to become an alternative fuel which is abundantly available in Indragiri Hilir district, especially in the Pulau Burung sub-district.  This study aims to calculate the electrical power generated from the utilization of coconut fiber as an energy source in Steam Power Plants. The method used in this research is to process quantitative data from coconut fruit production to obtain the availability of coconut fiber, generated calorific value, steam turbine output work and generated electrical energy. The results showed that the availability of coconut fiber with an annual average value of  1,058.405 kg/hour. The heat value from burning one kilogram of coconut fiber was 16,767.2967 kJ / kg. Using calculations, two steam power plant of electrical system designs were obtained, where the output power of the first unit generator was 647,7053 kW and the output of the unit two generating system is 289,2458 kW with a total electric power generated by the PLTU of 936.9511 kW.
