Electrical Agriculture Dryer for Water Hyacinth (Pontederia Crassipes) Stalks  / Garcia, Kim Andrea C.... [et al.].  -  March 2024  - 130 leaves :  28 cm. <br/><br/>Thesis <br/><br/> Cardona Rizal has been declared under the state of calamity due to the accumulation of water hyacinth (pontenderia crassipes) in Laguna Lake. One of their solutions in order to address this problem is to utilize it as a raw material for handicraft product. However, sun drying the water hyacinth stalks took 1-2 weeks to dry it completely. The research entitled “Electric Agricultural Dryer for Water Hyacinth (Pontederia Crassipes) Stalks” aimed to develop and innovate an agricultural water hyacinth stalks dryer. The study was conducted at Cardona Economic Center Cardona, Rizal by the Bachelor of Science in Mechanical Engineering Students during the 1st semester and 2nd semester of the School Year 2023-2024.  Examining the quality of dried water hyacinth stalks based on their appearance and tensile strength. The device's performance was evaluated based on drying time, drying rate, and electrical consumption. Following that, respondents analyze the device's acceptability in terms of functional suitability, maintainability, portability, reliability, usability and safety.  Research methodologies such as descriptive and developmental were employed to direct the research towards its intended goals. The acceptability of the research device was determined by a questionnaire modified by the researchers, following ISO/IEC 25010 standards, and completed by a total of thirty-one (31) respondents. Moreover, a mathematical formula from Philippine National Standards (PNS) PNS/BAFS 343:2022 ICS 65.060.99, Agricultural and Fishery Commodity Dryer —Testing Methods was employed to assess the efficiency of an agricultural dryer in drying water hyacinth stalks through electric drying techniques.  After evaluating and testing, the machine-dried water hyacinth stalks have successfully achieved a pale brown color without any molds and exhibit higher tensile strength compared to sun-dried water hyacinth stalks. To ensure optimal operation of the device, set the chamber temperature to 90 degrees Celsius. The dryer will need approximately 10 minutes to pre-heat, and each batch will take six (6) hours to dry. The machine excels in achieving faster drying rates while consuming less energy.  A user acceptance evaluation yielded positive results, with respondents commending the drying machine's functionality, ease of maintenance and transport, dependable operation, user-friendliness, and safety features. These attributes collectively demonstrate the machine's successful design and potential for widespread adoption.  The study discovered the efficacy of an electric agricultural dryer for processing water hyacinth stalks. This innovative technology consistently produces high-quality dried materials, regardless of weather conditions. The findings suggest that electric drying presents a reliable and weather-independent solution for utilizing water hyacinth as a sustainable resource.  The researchers strongly advise to investigate the possibility of using alternative sources of energy such as solar, wind and hydro energy to power the drying machine in order to reduce the amount of electricity consumed. Also to modify some parts of the machine which include to have it automatic specifically in unloading, added heating element, improvement in sealing and a light for a clearer vision of the user.
