<![CDATA[This research aims to analyze and model wheel-based floating energy generation technology. The current energy crisis requires us to look for sustainable solutions to meet energy needs. The Indonesian government has targeted renewable energy use of 23% by 2025, especially in remote areas. One solution to overcome this challenge is energy storage technology. Energy storage using floating technology is an innovative solution that is being developed. In this research, we analyze the design of a floating energy wheel with a capacity of 110 kW as an alternative source of electrical energy. Wheel energy is produced from a combination of buoyancy energy and energy originating from the weight of water which is produced by the difference in fluid density in the water and air environments. The research results show that this floating energy wheel can produce a torque of 7710,62 Nm and a power of 113,83 kW, showing great potential in renewable energy storage applications. Wheel-based floating energy generation technology has the potential to be an innovative solution in renewable energy storage. Further research needs to be carried out on a larger scale and field tests to validate the potential and efficiency of this technology in the real world]]>

<![CDATA[Water flow in irrigation is a means of obtaining electric power, which is commonly called microhydro. The waterwheel is the main component of the microhydro energy conversion process. The amount of energy converted by a waterwheel depends on the shape of its model, blade shape and the location of the installer. This study aimed to identify the characteristics of optimally efficient waterwheels. In addition to the energy of the place (i.e., the head), the influence of the weight of the water flowing into the blades of the waterwheel must be considered. This study also aimed to determine the effectiveness of mill performance by comparing waterways that use nozzles with those that use open canals. An experimental method was used to design a waterwheel system by testing the efficiency ratio between the nozzle line and the open canal. This test used the following variable water discharge rates: 12 m3/hr, 14 m3/hr, 16 m3/hr, 18 m3/hour and 20 m3/hr. Using the nozzle line with the largest discharge rate of 20 m3/hr, an rpm of 192.7 is produced with a torque of 0.7 Nm. The waterwheel produced 14.13 watts, with an efficiency of 64.75%. A line that used an open channel at the highest discharge rate of 20 m3/hr produced 61.7 rpm with 0.7 Nm of torque and 4.52 watts with an efficiency of 20.71%. The speed of water flow in the nozzle line was faster than in the open canal path, causing the tangential force on the waterwheel to be greater than on the open canal path. Based on these results, it was concluded that the path was the most efficient when using a nozzle.]]>

<![CDATA[Population An increase in population in an area results in an increased demand for clean water. Although water is abundant, about 97% of the water on Earth is seawater, which cannot be consumed directly because it contains harmful substances. Desalination process is used to convert seawater into drinking water by utilizing heat and wind speed. This research explores temperatures of 30℃, 45℃, 60℃, and 70℃ with a wind speed of 2.6 m/s. Data was collected for each temperature variation for 2 hours with records every 15 minutes, aiming to evaluate the effectiveness of evaporation and condensation in the desalination process. The results showed that 70℃ resulted in the highest evaporation (800 grams), although with a condensation rate of 26.25%. Condensate measurements showed a pH of 7.2 and TDS meter readings ranged from 125 to 138 ppm.]]>

<![CDATA[Indonesia, the largest archipelagic country in the world, possesses a vast marine area. Despite being surrounded by the sea, many coastal communities in Indonesia lack access to clean water. Seawater distillation presents a viable solution to this scarcity. This process involves separating salt from seawater to produce fresh water. This study aims to analyze the effect of nozzle spray pressure on the evaporation process of seawater to optimize fresh water production. Experiments were conducted using a fogging nozzle with a diameter of 0.3 mm, varying the nozzle pressure at 40 psi, 70 psi, and 100 psi. The data were statistically analyzed to determine the impact of nozzle pressure on seawater evaporation. The results indicate that the highest evaporation occurred at a nozzle pressure of 40 psi, yielding 10 g of condensed seawater, whereas the lowest evaporation was observed at 100 psi, producing 4 g.]]>

<![CDATA[The water crisis is a significant global problem, with more than 2 billion people lacking water and 1.1 billion having no access to clean water. Desalination, a method of converting seawater into fresh water by removing salt, is a potential solution to help coastal populations. This study aims to determine the convection and evaporation heat transfer coefficients and the effect of condenser cooling water temperature on the evaporation process and the increase in freshwater condensate. The research methodology involved the analysis of heat and mass transfer in a solar desalination system. A desalination device was designed to test the evaporation process with seawater temperature heated using halogen lamp light. Results show that increasing seawater temperature from 27°C to 42°C results in condensation when the temperature reaches about 30°C, affecting the water surface pressure and evaporation rate. Evaporation and condensation efficiencies are affected by convection and evaporation heat transfer, resulting in a convection heat transfer (0.84296 W/m2. °C) and evaporation heat transfer coefficient (23.81353 W/m2.°C). This research demonstrates the potential of solar desalination technology in producing clean water.]]>

<![CDATA[Aluminum 6061, a commonly used metal, demands critical attention in welding due to its mechanical properties influencing structural strength. The welding of aluminum 6061 is affected by various factors, including air velocity conditions during the welding process. This research objectives to analyze Vickers hardness values in TIG-welded Aluminum 6061. The research focuses on TIG welding of aluminum 6061, analyzing the impact of air velocity variations in the welding environment on hardness values. The experimental design considers air velocity variations at 3.6 km/h, 4 km/h, and 5 km/h during TIG welding of aluminum 6061. Specimens from each research variable undergo Vickers hardness testing to analyze the correlation between air velocity variations and Vickers hardness values. Research findings reveal specimen 1 with an average hardness of 96 HV, specimen 2 at 105 HV, and specimen 3 at 110 HV. These differences depict hardness variations among specimens, emphasizing the complexity of air velocity variations' effect on welded joints' hardness. Hardness testing results consistently show the lowest hardness values at point number 2, while the highest values for specimens 1 and 2 are at point number 6. However, specimen 3 exhibits the highest hardness at point number 8. The research concludes that air velocity variations in the welding environment significantly impact hardness values in the welding results. Vickers hardness testing indicates an increase in hardness values with increasing air velocity, highlighting a proportional relationship between air velocity variations and hardness values]]>

<![CDATA[Waterwheels are a medium for producing electrical energy in micro-hydro power plants sourced from waterways that have speed and height. The energy that can be obtained from a waterwheel should depend on the variation of the blades and the placement of the wheel but, the losses caused by wasted water are large. Therefore, this study makes an overshot waterwheel by using blade variations at the top to reduce losses and see the effect of these variations. This study uses 1 wheel with 4 variables: waterwheel without lid (T), waterwheel top blade closed 1/3 (T 1/3), waterwheel top blade closed 1/2 (1/2), and waterwheel top blade closed 2/3 (T2/3). This wheel uses mahogany wood and the blade cap uses acrylic with a thickness of 3mm. The waterwheel was tested using pipes with sizes and flow rates of 1 m3/hour, 2 m3/hour, 3 m3/hour, 4 m3/hour, 5 m3/hour, 6 m3/hour. The efficiency of the capless waterwheel is greater than the closed-blade waterwheel variation. In this study, the 1/3 closed blade waterwheel (T 1/3) is more efficient because the impact losses of the wheel (T 1/3) are lower at 720.13 when compared to the wheel without a lid (T) 1251.90 and the efficiency of the 1/3 closed blade waterwheel (T 1/3) is much higher at 64.38% when compared to the 2/3 closed blade waterwheel (T2/3) at 33.53%. Therefore, the results of this study show that the 1/3 (T 1/3) wheel is more recommended because it has a high enough efficiency and low impact losses.]]>
