| Abstract | Durianisahorticulturalcropthat startsbearingfruits from 5yearsafterplantingand will continue to bear fruits for more than 10 years if it is properly looked after. Now a day, due to lackof suitable machinery andequipment manual fertilizer applicationfordurianis commonly practiced which is expensive and resulted in fertilizer overused. Precision agricultural machinery will be able to reduce both labor cost and solve labor shortage problem at the same time. The optimal amount of fertilizer application is the function of machinery. The prototype of semi-auto fertilizer applicator for durian was designed for 27 hp tractor. It is suitableto work indurianplantation wheretheplantingpatternisoptimizedforagricultural machinery working. The spreader applicator unit is controlled by microcontroller while the position where fertilizer is applied is controlled by ultrasonic sensor attached at the front of the tractor. The fertilizer applicator unit works after the sensor detects a durian trunk and microcontroller makes an order; it starts working from one end of the durian canopy and stops when reaches the other end. The testing was done on 5 years old durian trees, at fertilizer spreader speed of 300 rpm. We found that at this speed the average working capacity was 6.28 rai/hr, fuel consumption rate was 0.14 liter/rai and fertilizer rate was 12.6 kg/rai. The break-even point was 450 rai/year. The return period was 4 years, annual working time 300 hrs. |
