Abstract

The type of drying device known as a hybrid dryer is a tool that harnesses solar energy and the heat generated by a biomass fuel-powered heat exchanger. This study was conducted to assess the performance of the hybrid dryer by analyzing the parameters of the device itself and the dried material. The research was carried out experimentally using a solar collector and a biomass furnace (as a heat exchanger) to heat the air. The solar collector used consists of 0.35 mm thick, black-painted zinc, coated with 5 mm thick glass, and installed at a 20-degree angle. The heat exchanger pipe used has a diameter of 1.25 inches and is made of galvanized pipe. The tested sample is corn seeds with an initial moisture content of about 24.6%. The experimental results show that in the drying process using a solar dryer, the initial moisture content of 24.8% was successfully reduced to 14% at 5.50 h (rack 1), 6.50 h (rack 2) and 7.00 h (rack 3) with a thermal efficiency of 24.25%. Meanwhile, in the hybrid drying process, the required time is approximately 5.00 h (rack 1), 5.50 h (rack 2) and 6.00 h (rack 3), with a efficiency of the drying equipment used is 21.048±5.690% (hybrid) and 22.706±6.437% (solar).

Abstract

The primary challenge in post-harvest corn handling among farmers in Bibiosi Village, Keerom Regency, is the continued use of manual shelling tools, which are time-consuming and labor-intensive, resulting in delayed sales and reduced corn quality. To address this issue, appropriate technology in the form of a gasoline-powered mechanical corn sheller (5.5 HP) was introduced to improve processing efficiency and productivity. The program aimed to increase farmers’ shelling capacity, enhance income, promote technology adoption, and strengthen collaboration among Cenderawasih University, the local community, and the local government. The implementation method included machine fabrication, equipment installation, operational and maintenance training, and evaluation. Performance testing demonstrated that the machine has a production capacity of 350 kg per hour. The application of this technology significantly improves post-harvest efficiency and contributes to increasing farmers’ productivity and welfare. Furthermore, the program fosters technological awareness and encourages a more progressive mindset within the farming community.
