Abstract

Corn cobs, an abundant agricultural waste, represent a promising alternative energy source when converted into briquettes. This study aimed to characterize corn cob briquettes and determine the optimal adhesive type and concentration for enhanced performance. Charcoal was produced from corn cobs via pyrolysis in repurposed oil drums, then ground and sieved through a 60-mesh screen. The resultant charcoal was combined with either starch or sago starch adhesives at concentrations of 7.5%, 10%, 12.5%, and 15% and subsequently molded into honeycomb briquettes using a 4-inch diameter mold with 16 perforations, fabricated from galvanized iron pipes and operated with a hydraulic jack. Proximate analysis indicated moisture levels of 5.37–6.71%, ash levels of 30.64–39.16%, volatile matter levels of 20.61–23.07%, fixed carbon proportions of 32.53–42.44%, and calorific values between 2893 and 3727 kcal/kg. A Water Boiling Test conducted with 1 liter of water demonstrated that briquettes incorporating 7.5% sago starch adhesive achieved boiling within 36 minutes, indicating superior combustion efficiency. These findings confirm the potential of corn cob briquettes as a renewable energy source and underscore the critical role of adhesive formulation in optimizing biomass fuel performance.

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).
