Introduction to Solar Energy and Its Potential

Solar energy is a renewable energy source that has great potential to be utilized, especially in areas with tropical climates. The use of solar energy is becoming increasingly popular due to its numerous benefits, including reducing dependence on conventional energy sources, lowering production costs, and minimizing environmental impact. In this study, the drying of coffee beans was carried out using solar collectors with a pinnate flat plate design as a solar energy service. The main purpose of this study is to produce effective prototype designs, so that it can be used by the wider community.

Design and Construction of the Surya Collector

The design of this tool consists of two collectors, namely one collector that has a slope angle of 0 degrees and one other collector with a slope angle of 20 degrees. The size of the two collectors is identical, which is 1.13 meters x 1.13 meters, with a total thickness of 0.15 meters. Collector maker material consists of double glazing that uses glass. The use of glass as a collector material provides excellent thermal insulation, allowing the collector to absorb and retain heat efficiently.

Performance Test of the Surya Collector

The results of the collector performance test show that:

Maximum Temperature: The maximum temperature of the air flowing in the collector reaches 62.94 °C. This high temperature indicates that the collector is able to absorb and retain heat efficiently, making it suitable for drying coffee beans.
Total Energy Received: The total energy received by the collector is 41.21 MJ. This high energy input is essential for drying coffee beans quickly and efficiently.
Total Energy Wasted: The total energy wasted by collectors reached 8.84 MJ. This energy loss is minimal, indicating that the collector is designed to minimize energy waste.
Total Net Energy Received: The total net energy received by the collector is 32.37 MJ, so the overall efficiency of this tool reaches 78.55%. This high efficiency indicates that the collector is able to convert solar energy into usable energy efficiently.

Advantages of the Fixed Flat Plate Design

The design of a fixed flat plate in the collector has its own advantages. These fins increase surface areas for sunlight absorption, thereby increasing energy conversion efficiency. With a different slope angle, collectors can be optimized to absorb sunlight throughout the day, depending on the position of the sun. This design allows the collector to absorb sunlight efficiently, making it suitable for drying coffee beans.

Efficiency and Performance of the Surya Collector

The efficiency of tools that reached 78.55% show that this tool has excellent performance in absorbing and utilizing solar energy. The clean energy received allows users to dry coffee beans faster and more efficiently, which in turn can improve the quality of the coffee produced. The high efficiency of the collector makes it an ideal solution for coffee farmers in the tropics, helping them in improving crops and reducing production costs.

Conclusion and Future Development

The success of this research opens the way for further development in the use of renewable energy technology for agricultural applications. With the right design and sustainable innovation, this tool can be a very useful solution for coffee farmers in the tropics, helping them in improving crops and reducing production costs. The use of solar energy can also reduce dependence on conventional energy sources, making it an environmentally friendly solution. Further research can focus on optimizing the design of the collector to improve its efficiency and performance, making it a more effective solution for coffee farmers.
