Abstract
The government has budgeted assistance/grants continuously many bed dryers to farmers but many of them were not used because farmers felt that the drying production rate of rice is more expensive than the traditional open sun drying. The farmers choose to go back to the traditional way that takes the drying process longer than using the dryer. For 1 year, open sun drying can process 100 batches, and dryer can process 450 batches. This research tries to solve the high cost problem by looking for a new alternative solution. The solution is replacing the oil burner with a rice husk burner, which is appropriate both economically and environmentally. For the stirring mechanism, this system must continuously stir up the pile of grains during the drying process. The point must be fulfilled is that the total cost of the drying process should not rise, especially the cost of the stirring process. A stirrer mechanism that needs smaller power than the maximum power setting is made. Farmers’ income for this innovative modification will get a 332% increasing profit than using oil burner bed dryer machine and will get a 41% increasing in welfare than using the standard husk burner bed dryer.
Highlights
To support the agricultural economic cycle, stimulate/promote agricultural growth [1], and support independence food security and agricultural [2], the Government through the Ministry of Agriculture has budgeted assistance/grants continuously in Indonesia
This innovative solution must utilize biomass or rice husk as a heat source as an alternative substitute for existing burning oil, and must be able to dry the grains with the same quality like a standard flatbed dryer but it is more efficient in the operating cost, and in total, must provide more lower in drying cost rate
It must use rice husk or biomass as a calorie-producing ingredient; Total drying production cost rate must be lower than the traditional bed dryer, and even the ordinary drying process by drying and utilizing sunlight; Do not require human assistance during the drying process other than one operator who oversees and runs the machine; Firm and has a long useful life investment; Safe in operation; The new system is an attachment to ordinary flatbed dryer so it should utilize the same body/chamber of ordinary one; It must be ensured that the operator or human skin contact involved is a little possible with grains
Summary
To support the agricultural economic cycle, stimulate/promote agricultural growth [1], and support independence food security and agricultural [2], the Government through the Ministry of Agriculture has budgeted assistance/grants continuously in Indonesia. To minimize the post-harvesting losses and increase the quality of grains in the rice production cycle, it is important for farmers to involve mechanization in the rice drying process. We should directly dry the grains less within 24 hours to minimize those losses and evaporate the moisture content inside the rice and reduces it from 24% - 26% on a wet basis after harvested to at least 14% and a good 12%. A drying process that is not complete or even late/delay will cause a loss in quality and/or quantity of grains. The Indonesian National Budget (APBN) has been allocated for many years and some of it had been delivered hundreds of Flat Bed Dryer grants from the Ministry of Agriculture and the Ministry of Village, Development of Disadvantaged
