In a more specific case, the Free Water Flow (FWF) turbine is very promising in terms of its development concept, which mimics the phenomenon of the ability to swim swan's feet. Therefore, the purpose of this study is to further study the FWF turbine in terms of (1) its current capabilities in actual application in irrigation canals and (2) determine the direction of its development in the future by maximizing existing resources. The experimental research method is carried out through the stages of the process which include (1) development plan and design of water turbines according to irrigation channels, (2) design and implementation of Hydro's Agriculture-Friendly Turbines. The construction was built in the watercress farming area of Sumbergelang, Sumberdem, Wonosari, Malang Regency. Findings from this study reveal a significant correlation between the utilization of parallel turbine in irrigation canal and cost efficiency and improved output energy. Apart from sunlight, light sources can also be obtained from lighting (UV) by utilizing potential energy sources in rice fields (irrigation) through energy harvesting from an FWF Turbine. This research contributes valuable insights to the ongoing development of parallel turbine in agricultural area for support sustainable agriculture. [ABSTRACT FROM AUTHOR]

The need for renewable energy demand is currently growing very rapidly, and this very rapid development makes the exploitation quite large, one of which is wind energy. The need for monitoring the potential of wind energy to know the speed of wind energy that blows in a location in one day. The results obtained show that the faster the wind rotation (wind turbine blades), the greater the voltage generated, namely the wind speed is directly proportional to the voltage, in the measurement at 07.00 am to 05.00 pm the lowest wind speed is 1.31 m/s with an output voltage of 12.31 VDC. and a current of 0.26 A at 08.00 am and the highest wind speed is 5.13 m/s with an output voltage of 12.73 VDC and a current of 0.29 A.

Link and match is one of the government programs to increase the relevance of vocational education to the needs of the industrial world. The Department of Electrical Engineering, Faculty of Engineering, State University of Malang runs this program with partner industries to develop a learning curriculum for vocational-based study programs. The learning curriculum developed includes lesson plans and learning modules based on the massive open online course (MOOC) on solar power plants in renewable energy courses. This MOOC development is based on the ADDIE development method. This MOOC is also structured to improve the technical skills and employability skills of students taking renewable energy courses, especially on the topic of solar power generation. MOOC validation was carried out by material and media experts from industry and academia and involved respondents, namely students. The results of the validation carried out obtained a validity level of 91.25%, so that the product is declared feasible to be implemented in learning. [ABSTRACT FROM AUTHOR]

Electrical energy in Indonesia comes from various power plants. One of the energy sources used is solar energy with a usage percentage of 0.003%. The potential for the use of solar energy is still very large, especially in Indonesia with tropical regions. Solar energy can also be used in making learning media in the form of trainers. Based on trainer observations conducted at the Energy Conversion Laboratory of the Department of Electrical Engineering Universitas Negeri Malang, Indonesia, there are solar power generator trainers that not suitable to support the Energy Management Course because there are no energy production control and load management features. While The energy management course discusses control of energy production and load management, so it is necessary to develop trainer to achieve the learning objectives of energy management courses. The development model used in this research is based on Sugiyono's model. The validation process was done by expert 1 and expert 2 while the product also was tested on undergraduate student in the Electrical Engineering and vocational student of Electrical Engineering who have already studied about Energy Management Courses. The validation result of trainers shows the average percentage of 94.2% while the job sheets as the support material for trainer has validated with the average percentage of 94.3%. This result shows the eligibility category is very feasible. Furthermore, the testing result of trainer which is done by students has the average percentage of 93.1% while that of the job sheet has the average percentage of 92.8%. This result means that the eligibility category in the testing case is also very feasible. From the results of the data analysis, it can be concluded that the IoT-based energy monitoring system trainer and the energy management job sheet is feasible to use in the learning process of the Energy Management Course, Department of Electrical Engineering, Universitas Negeri Malang, Indonesia.

In general, one of the main components used in electric power systems is a transformer. In principles, this equipment uses a magnetic process through the pairing winding where a cooling system is also applied to maintain the expected operational performance and to maintain heat transfer during the power delivery. In fact, load demand changes fluctuate depending on the behavior of energy users. This research is conducted to evaluate heat transfer in a three-phase transformer. This work also takes into the flowing current gradually based on the heat generated in the transformer. To cover these objectives, the analysis is directed to the power transformer optimization using the Artificial Salmon Tracking Algorithm (ASTA) for performing heat flow rates on-demand changes. The results obtained indicate that ASTA has a potential implementation for determining the optimal heat transfer. The demand changes have affected the power loss detected in both windings which are migrated out of heat through the cooling and fluid systems. [ABSTRACT FROM AUTHOR]

Recently, alternative energy becomes a popular issue associated with decreasing fossil energy source consumption. Moreover, this aim leads to renewable energy conservation for exploring potential sources, such as, solar and wind energy, which are more familiar than other energy sources. However, renewable energy usage is very dependent on the existing technology development which is applied to catch the natural energy sources. These works are subjected to study and estimate the downstream speed on the wind energy as a potential renewable energy source which is utilized for the wind farm energy harvesting. These works also consider the 24 hours operation based on technical parameters of the wind turbine and natural wind speed performances. These studies are demonstrated on the random surface roughness performing using an artificial salmon tracking algorithm. Results show that the random surface roughness influences the pattern of wind dispersion and wind speed reduction, as well as sweeping areas affected by the wind. It also has an impact on energy production related to the wind farm energy harvesting. Regarding the surface roughness within 0.01-0.936 randomly, the downstream speed covers 3.842-5.053 m/s. In particular, the wake decay also contributes to the wind sweeping in the harvesting potential energy area. By considering the hub high of 10 m, the highest downstream leads to the slowest speed on the constant wind flows. [ABSTRACT FROM AUTHOR]

In this paper, a safety of hazardous gas instruments for laboratory experiments was designed using a microcontroller and connected to personal computer to save the data. Here, the carbon monoxide gas (CO) and methane gas (CH4) sensors are applied to the systems to measure the concentration of gases in case of laboratory. Commonly, the gas instruments are used in object tested directly without considering the flow of gases toward the user. Comparing to that system, in order to protect the users’ safety from of direct contact with the gases, inlet-outlet pipes and fill-discharge tubes are used in this proposed system. The performance of the proposed system is analysed trough experiments. Some results were presented according to the time of activating inlet to inject the gas. Thus, the effect of changing the gas concentration was analysed. [ABSTRACT FROM AUTHOR]
