Abstract
Oil palm harvesting activities require effort, energy, and techniques to obtain quality results. The oil palm harvest will pass through the stage of transferring the harvest into a transport truck, which is a manual transportation stage. In addition, the harvested palm oil will be weighed before being transported to the transport truck, this weighing activity is usually carried out using a manual hanging scale so that workers have to lift the harvest to the scales and lower it back which is done repeatedly. This will result in a lack of work efficiency, for that we need a means of transportation that can maximize the efficiency of workers in weighing activities and moving crops into a transport truck. One alternative that can alleviate the problem above is a belt conveyor with innovations in the feeder conveyor. The innovation is automation in the form of weighing load cells using an LCD as well as a pneumatic system to drive crops to the conveyor, so a belt conveyor model is made with automation innovation on the feeder conveyor. The design of this model used ASTM A36 steel for hollow iron as the foot frame, type C iron for the frame feeder, 1 mm thick flat plate plate, and 1 mm thick surface plate. The feeder conveyor is designed using SolidWork software. The manufacture of the pneumatic system uses a double acting cylinder actuator component, mechanical hand valve control 5/2, compressor, hoses, one way flow control, fittings, and silencers. The design of a pneumatic system in the form of a system circuit and also a simulation through Festo Fluidsim software. The manufacture of the load cell system used a load cell sensor with a capacity of 20 kg, amplifier module HX711, Arduino Uno, LCD, Arduino box, and several jumper cables. The load cell system is designed through the Arduino IDE software which as the input software a command to run the load cell system. The results of the load cell weighing have a success percentage of ±99%, which means it has an error of ±1%. The travel time of the pneumatic system to push the harvest to the belt conveyor takes ± 1 second to go forward and ±0.6 second to go backwards, it can be concluded that the feeder conveyor has a double-function feature, namely weighing the mass of palm fruit and pushing the palm fruit towards the belt model conveyors.
