Abstract

Magnetohydrodynamics is a method for generating electricity by utilizing the interaction between a magnetic field and an electrolyte fluid. MHD components: salt water electrolyte, Neodymium N52 magnet, and Cu-Zn electrode. The MHD used is a coarse salt water electrolyte. The purpose of the MHD model is as an innovative technological breakthrough that is used to support increasing the efficiency of the power generation system. The lowest efficiency is shown in the second data with variations in salt content of the 5 grams/liter experiment without MHD support, which is 0.08%. The highest efficiency is shown in the twentieth data with variations in salt content of the 95 gram/liter experiment supported by MHD, which is 0.59%. The maximum efficiency increase that can be achieved is 0.37% with variations in salt content of 60 grams/liter.

Abstract

””Overcurrent Relay is one of the protection system tools in the electricity network. Overcurrent Relay works based on the increase in fault current that exceeds a certain safety value and a certain period of time. The type of relay that will be used in this test is the IDMT NX203A Overcurrent Relay. The purpose of this test is to get a good practicum module and to prove the inverted time relay characteristic curve according to British Standard BS142. In the test, the tool to be assembled is tested for its work function so that in data collection errors can be avoided while the relay on the module will be given a current setting of 2A; 3A; and 4A with TMS0.05; 0.5; and 1.0 which will be connected to a digital timer so that if the fault current exceeds the setting current, the relay will automatically give a signal and the digital timer will show the time when the current is cut off. The final result is a practicum module where each tool functions under normal working conditions and a graph of time against relay current for setting current 2A, fastest time 0.498s at 9A fault current and 0.05 TMS, longest time 12.991s at 4A TM fault current. . 1.0. Current setting of 3A for the fastest time is 0.572s at fault current of 9A and TM 0.05, for the longest time is 35.854s at fault current of 4A and TM 1.0. Current setting of 4A for the fastest time is 0.708s at fault current of 9A and TM 0.05, for the longest time is 55.979s at fault current of 5A and TM 1.0.

Abstract

The savonius wind turbine with variations in the diameter of the sweep and the air gap is a technological innovation with treatment using changes in the diameter of the sweep and the distance of the air gap between the blades. And it has low self-starting and relatively high torque. The purpose of the study was to create five models and test the performance of the Savonius wind turbine with variations in sweep diameters of 500 mm, 480 mm, 460 mm, 440 mm and 420 mm with air gaps of 30 mm, 50 mm, 70 mm, 90 mm, and 110 mm. . And analyze the turbine performance to get the best Coefficient of Power (CP) from the five turbine gaps. The stages of the research method include the preparation of a literature search, turbine design planning, tool making, tool testing, data collection, data analysis, and the final stage. The results of the tests carried out showed that the Savonius turbine with an air gap of 70 mm with a CP value of 0.232 had maximum work at low wind speeds (4 m/s) and at high wind speeds (10 m/s). obtained a CP value of 0.0695

Abstract

The purpose of making this final task is to apply the solar power system as a source of electrical energy to move the water pump automatically in fish ponds. This system works automatically with the Water Level Control tool sensor (WLC), so that if the water level drops or rises then the water pump will automatically work. On this automated system use the Smart Relay SR2B121BD and the ZelioSoft 2 application. Data retrieval carried out at 10.00 -14.00 WIB, obtained data pumps 1 and 2 for a height of 1 cm for 30 minutes and a height of 2 cm for 70 minutes. The amount of discharge the pump produces 1 and 2 ranges from 37 L/M to 45 L/M. Pump 1 Test results obtained an average efficiency of 7.68%, with the highest efficiency of 11.03% and the lowest efficiency of 5.26%, while the average pump efficiency of 2, 7.05% with the highest efficiency of 10.66% and the lowest efficiency of 5.41%. The average efficiency of the solar panels is 11.20% with the highest efficiency of 14.60% and the lowest efficiency of 7.29%

Abstract

The important matter about biogas as an alternative energy source was the presence of hydrogen sulfide (H2S) which is very corrosive. The biogas desulfurization process was absolutely necessary to reduce the risk of damage to the equipment. For small-scale applications, the selection of the type of adsorbent became important to reduce additional costs. One alternative material that can be used was iron gram waste. The aim of this study was to investigate the use of iron gram waste resulting from the machining practicum process at the Department of Mechanical Engineering, Politeknik Negeri Semarang as an alternative material for making adsorbents. Iron gram waste was processed into Iron (III) Oxide (Fe2O3) and Iron (III) Hydroxide (Fe(OH)3), formed into billets with an average billet mass of 250 gr. The performance test of the adsorbent in the biogas desulfurization process was carried out under conditions of variation in the flow rate of biogas feed 1, 2, and 3 liters per minute, and the volume of biogas purified in one process was 50 liters. As a result, the most optimum performance was obtained in the test with a feed biogas flow rate of 1 liter/minute, with a percentage reduction in H2S levels contained in the biogas by an average of 82,56%.

Abstract

Energy audit is very necessary to calculate the level of energy consumption of a building or buildings. The research includes the amount of energy consumption based on the initial energy audit and detailed energy audit as well as saving opportunities based on conditions in the field. Based on the initial energy audit, the value of the Energy Consumption Intensity (IKE) is 0.699 kWH/m2month, while in the detailed audit the IKE value is 0.935 kWH/m2month. Based on the results of a detailed energy audit, the lighting measurement of 325 lux still meets the requirements for a classroom with a standard between 250 lux to 500 lux.

Abstract

The benefits of reading while listening for English as a Foreign Language (EFL) learners have been investigated in different EFL learning contexts. Some studies found that simultaneous reading while listening promotes positive impacts on students’ reading and listening skills. It also helps L2 learners’ fluency and comprehension of reading and listening. Moreover, it can assist L2 learners in acquiring new language input in a new learning environment. Hence, this article reviews some research papers related to the implementation of reading while listening (RWL) program in EFL learning context. Furthermore, to answer the research questions: 1) What is reading while listening?; 2) What are the effects of using reading while listening for EFL learners? How to apply the reading while listening program within the EFL classroom? To answer these questions, this article examines the use of RWL for EFL learners based on the research methodology, subject, instrument used, result and suggestion, including the principles of implementing simultaneous reading and listening within the EFL classroom. HIGHLISGHTS Highlights Reading While Listening (RWL)simultaneously can support students with low reading or listening fluency rate. Simultaneous reading while listening affects students reading and listening skills for a long period of time. A guideline of RWL program implementation based on ER/EL principles is discussed thoroughly.

Abstract

Thinking is one human trait. Since can perceive, people begin to think, and this process continues until the end of his life. Attitude and way of thinking can be developed through a process of learning mathematics because mathematics has a structure and a strong and clear linkages intracompany so anyone who thinks rationally skilled study. Therefore, learning how mathematics can be implemented so as to cultivate students' mathematical power. Mathematics curriculum should be designed not only for students continuing on to higher education but also for entering the job market. Focus of the curriculum can be examined from three aspects, namely Intended Curriculum, Curriculum Implemented and Attained Curriculum. Learning process must be conducted in accordance with the class learning objectives to be achieved. Also, it can also refer to the implementation of the curriculum in other countries.
