Abstract

Silica gel has been widely used as a dryer for food, medicine and various other purposes. Silica gel is basically a safe material, but because of its hydroscopic nature, silica gel is easily contaminated with dangerous materials. Apart from that, silica gel cannot decompose easily naturally, so using large amounts of silica gel will cause piles of silica gel waste. Therefore, efforts are being made to find replacement materials, one of which is using rice husk ash which can easily decompose naturally. This research aims to test the ability of rice husk ash as a substitute for silica gel. Tests used commercial silica gel (SG), silicon gel in non-woven geotextile bags (SG-N), and rice husk ash in non-woven geotextile bags (AS-N). In this study, AS-N was compared with SG and SG-N. The water vapor absorption test was carried out on a weight of 15 grams for 180 minutes. Each of the three samples was placed in a closed jar to avoid contamination with water vapor in the environment. The relative humidity of each jar was measured with a hygrometer. The jar lid was kept closed throughout the test. The results showed that SG, SG-N and AS-N reduced humidity by 23%, 22% and 24% respectively. Modeling with the Avrami equation is used to extrapolate the absorption results. The research results showed that 15 gram non-woven geotextile rice husk ash had superior water vapor absorption capabilities compared to silica gel and silica gel non-woven geotextiles. So it can be concluded that dryers with rice husk ash as the basic material can be used for needs such as clothes dryers, food dryers and other needs

Abstract

TThe manual measurement of materials using pneumatic systems for inspections remains prevalent, posing challenges in meeting the demands and speed of modern production processes. To address this, there is a critical need for an automated inspection tool capable of generating a significant number of inspection inputs. This research objectives to design and implement an automatic thickness inspection system, employing pneumatic technology and inductive proximity sensors. The study adopts an experimental research design, systematically progressing through literature review, algorithm design, PLC programming, and comprehensive testing. The pneumatic system, known for its high response speed and durability, is capable of accurately measuring material thickness and sorting items with precision. The integration of inductive proximity sensors enhances the system's efficiency in detecting both metallic and non-metallic objects. The research findings reveal a system effectiveness of 95.8% in the initial test and 91.7% in the subsequent test. Notably, deviations in the Ø12 sensor are identified in detecting NG minus material. Despite this, the system's overall effectiveness surpasses the 90% threshold, meeting stringent standard criteria. The study concludes with insights into the identified deviations and underscores the system's effectiveness in meeting high-standard criteria. Recommendations for improvement include modifications to the stopper or proximity sensor position, sensor recalibration, continuous monitoring, and material path separation

Abstract

In this work, the performance of a buoyant waterwheel to produce hydrokinetic power is investigated through analytical theory and computational fluid dynamics simulation. The impact of the buoyancy wheel is investigated by establishing the performance parameters through the use of a moving mesh approach and a realizable k-ε turbulence model. Transient simulation is required to comprehend the flow of physical processes. Using moving mesh as a transient methodology of the buoyancy waterwheel, numerical flow simulations and theoretical analytical methods are used in this study to assess the effect of buoyant force generated on the performance of the buoyancy wheel. The buoyancy waterwheel that will be put to the test has eight straight blades and a diameter of one meter. The pinwheel force and torque created in the numerical flow simulation (CFD) are 414.96 N and 207.48 Nm, respectively, whereas in the theoretical calculation they are 449.06 N and 224.53 Nm, according to the research findings. It is possible to compute the buoyancy wheel's power output and efficiency mathematically, yielding values of 1619.35 W and 68.07%. The buoyancy wheel's power output and efficiency, as determined by numerical flow simulation, are 1495.95 W and 62.88%, respectively. Based on theoretical and CFD study results, the buoyancy wheel generates a standard deviation of 7.62%. Thus, for the buoyancy wheel, a temporary method that makes advantage of the moving mesh characteristic is advised. This method can also be applied as a future alternative energy source for the Piko hydro turbine

Abstract

Due to environmental changes, ensuring access to clean water is challenging for many regions. This study examines how wind speed influences seawater evaporation rates in a desalination system. Conducted indoors, the research varied wind speeds (0.6 m/s, 0.7 m/s, and 0.8 m/s) while maintaining a consistent temperature. A modified window Air Conditioner (AC) served as the evaporation unit, with its condenser immersed in water to utilize released heat, and its evaporator used as a condenser. Water temperature was maintained at 60-70°C. Results demonstrated a significant increase in evaporation rates with higher wind speeds. The strong correlation between experimental and theoretical results underscores wind speed as a critical factor in enhancing freshwater production efficiency from seawater. These insights inform the design of more effective desalination systems, offering potential solutions to water scarcity challenges in vulnerable regions
