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

This study investigates the viability of corn byproducts as an alternative energy source via conversion into honeycomb charcoal briquettes. Discarded corn byproducts are transformed into briquettes to mitigate fossil fuel reliance, particularly in the Arso region. This research aims to assess the energy output of briquettes with varying perforation configurations (4, 8, and 12 holes) and a diameter of 5 inches. The Water Boiling Test (WBT) method, utilizing temperature measurement tools such as a K-type thermocouple and an infrared thermometer, was utilized for performance assessment. One liter of water was heated to its boiling point during the experiment. The results indicated that the 8-hole briquette had the quickest boiling time of 25 minutes, with a fuel consumption rate of 2.8 × 10⁻³ kg/s. In comparison, the 4 and 12-hole briquettes required 35 minutes, with an average fuel usage of 2.86 g/s. The maximum combustion temperature for the 4-hole briquette was measured at 589°C, while the 12-hole briquette reached a mere 427°C. These outcomes demonstrate that the 8-hole briquette possesses superior efficiency. A decrease in hole quantity adversely affects boiling speed, while an increase in holes results in greater fuel consumption. These findings highlight the importance of optimized briquette design in improving biomass fuel efficiency.

Abstract

The application of carbonization or carbonization model technology to reactor equipment uses a closed method. The purpose of using a closed system is to produce high quality carbon which is shiny black in nature and breaks easily when pressed with the thumb. This technological method is very practical for the community to apply both in the manufacture of reactors and the carbonization process to the manufacture of charcoal briquettes. The reactor can be made from used compressor cylinders or 12 kg gas cylinders. The material is then modified into a reactor device where combustion is carried out in the reactor tube. In the process of carbonizing biomass, neither agricultural nor industrial waste needs to wait until it turns into carbon, in this case black granules. In this training, participants were first provided with theory and explanations about the use of reactor tubes starting from the manufacturing process to carbon production. In making briquettes, several stages are carried out, including drying, waste sorting, carbonization, mixing with adhesive to printing with a briquette size of 3.18 cm and drying using an oven or sun. so that participants can practice at home. This training can provide skills to the participants, as well as open the mindset of how to use the waste around it to be used as a solid alternative fuel. It can also be used as a home industry business so that it can improve the household economy.

Abstract

The potential natural resources of Keerom Regency, Arso District, especially in the agricultural sector, are very abundant. Corn cob waste produced by farmers is a loss if it is not converted into something more useful. Corn cobs contain cellulose, hemicellulose, and lignin. This content will later be converted into smaller molecules through various treatments to be used as energy. This service aims to provide knowledge and skills to the farming community, on how to process corn cob waste as solid fuel or briquettes. The results of proximate testing or the composition of corn cob briquettes carried out in the Unhas Animal Husbandry Laboratory showed that at the highest temperature of 100oC, fixed carbon was obtained at 39.7, and at the lowest temperature of 60oC, fixed carbon was at 41.3. This can be stated as the amount of carbon contained in the remaining material after the volatile matter has been removed. Likewise, the higher the fixed carbon value, the quality of the corncob briquettes increases. Thus, the highest energy or heat pattern obtained is 5933 cal/gr, so corn cob briquettes can be used as briquette fuel energy. Utilizing corn cobs as fuel for briquettes can reduce dependence on fuel oil and can be used as a home industry business.
