Abstract

The finned drive wheel technology is widely used for wet rice fields. Currently, finned drive wheels for peat fields have not been developed and still use traditional agricultural tools such as hoes and sickles, while the finned drive wheels for wet rice fields are not yet able to work optimally on peat rice fields. The driving wheel model and testing in peat rice fields were carried out in this research. Design and manufacturing were carried out by referring to previous research literature. This initial research was carried out in wet rice fields on open-close finned drive wheels and standard finned wheels, with the aim of measuring the comparative level of performance of the two wheel models. The wheel performance measured is sinkage and wheel rotational speed. The research produced two models of driving wheels, namely the standard fin type with a driving wheel diameter of 35 cm and a number of 8 fins and the open-close fin type producing a driving wheel diameter of 40 cm with 4 arcuate fins on the top surface of the driving wheel. Standard fin type drive wheels have smaller sinkage (11% on average) compared to open-close fin type wheels. The finned drive wheel with the open-close type has an average speed level that is 27.7% higher when compared to the standard finned type.Keywords – wheel drive, standard fins, open-close fins, sinkage, wheel speed

Abstract

Industrial applications, machinery and engineering construction, strain is the most important value for determining the selection of suitable and appropriate materials for designing machine elements, with advances in strain measurement analysis technology on Arduino microcontroller-based structures it is very possible to use it. Several studies have succeeded in measuring strain using an Arduino Uno-based strain gauge. Based on the above, it is possible to design a strain measuring tool using an Arduino Uno-based strain gauge to support students' practicum process, so in this research a design of a strain measuring tool using an Arduino Uno-based strain gauge was carried out. The research results have completed the design of a strain measuring tool using an Arduino Uno based strain gauge and can be used on a student practicum scale. The results of tests carried out on Nako iron rods show that there is an appropriate relationship between the load applied, the strain measured and the stress produced. The results of the tests carried out measured the amount of strain produced at various loads such as at a load of 1,000 grams the strain was measured at 0.5345 and a stress of 106.9 MPa. Meanwhile, at a load of 2,000 grams, the strain reached 0.573 and the stress was 114.6 Mpa.
