Design Of Prototype Prototype Surya Collector Flat Plate Type For Heat Producing In Agricultural And Plantation Product Dryers
Introduction
The drying process is an essential method for reducing water content in agricultural products. One common method used by farmers in Indonesia is to dry the harvest directly in the sun. Although this method is easy and cheap, it faces many obstacles, especially related to uncertain weather factors. Sudden weather changes can affect the quality of the harvest that is being dried. If the water content is too high due to insufficient heat to reduce moisture, the product can experience microbial or fungal growth, which in turn can cause decay. Therefore, we need a tool that can help farmers to maximize the process of drying their agricultural products.
The Need for a Solar Collector
In Indonesia, the conventional drying method is often affected by weather conditions, which can lead to a decrease in the quality of the harvest. This can result in significant economic losses for farmers. A solar collector is a tool that can help farmers to overcome this challenge by providing a consistent and reliable source of heat. By utilizing solar energy, farmers can dry their products more efficiently and effectively, resulting in higher quality products and reduced post-harvest losses.
Design of the Solar Collector
The solar collector designed in this study is a single plate type with a size of 2 m x 2 m x 0.17 m. This collector consists of several layers that function as insulation, namely layers of wood, sterofoam, and rockwool. Aluminum is used as a heat absorbing plate, while glass functions as a cover to optimize sunlight. The collector is designed to absorb heat from the sun and transfer it to the drying room, where the agricultural products are placed.
Design of the Drying Room
In addition to the solar collector, the drying room is also designed to facilitate the drying process. The drying room has a size of 2 m x 1 m x 1 m and is equipped with a ventilation system to ensure proper airflow. The drying room is designed to provide a controlled environment for the drying process, allowing farmers to monitor and control the temperature and humidity levels.
Testing and Analysis
In testing this tool, the sample used consists of cassava (manioc) and red chili. During two days of testing on sunny weather conditions, data obtained about collector efficiency. The analysis shows that the average heat radiation that can be absorbed by the collector is 1856,755 watts. In addition, the average heat loss in the collector was 442.57 watts, which indicated that this tool could still be improved to improve its performance. The average efficiency of solar collectors obtained during the testing process reached 69.70%.
Additional Analysis and Explanation
The solar collector type of flat plate offers an effective and efficient solution to overcome the problems faced by farmers in the drying process. By utilizing solar energy, this tool not only reduces dependence on the weather but also improves the quality of agricultural products. Efficiency of 69.70% shows that this tool can work optimally under certain conditions, and there is still space for improvement so that its efficiency is increasing.
Sustainable Agricultural Context
In a sustainable agricultural context, the use of technology such as solar collectors is in line with the aim of increasing agricultural output while reducing environmental impacts. Better drying has the potential to produce high quality products and reduce post-harvest losses that often occur due to decay.
Future Research Directions
In the future, further research can be done to improve the design and materials used in collectors, as well as expand the application of this technology for other types of agricultural products. With this innovation, it is hoped that farmers in Indonesia can be more independent and productive, and be able to compete in the global market with better results.
Conclusion
The design of the prototype solar collector flat plate type for agricultural and plantation product dryers is a significant innovation in the field of agricultural technology. By utilizing solar energy, this tool can help farmers to overcome the challenges of drying their products, resulting in higher quality products and reduced post-harvest losses. Further research is needed to improve the design and materials used in collectors, as well as expand the application of this technology for other types of agricultural products.
Limitations and Future Work
The current design of the solar collector has some limitations, such as the need for further improvement in its efficiency and the expansion of its application to other types of agricultural products. Future research can focus on improving the design and materials used in collectors, as well as exploring new applications for this technology. Additionally, further testing and analysis are needed to validate the performance of the solar collector under different weather conditions.
