Perancangan Prototype Alat Penakar Adonan Tepung Kue Donat

Abstract

Sumber Rejeki, is a Small and Medium Enterprise (SME) engaged in cake ingredients industry located in Sidomukti district, Salatiga. In addition to the cake making, Sumber Rejeki also sells practical cake flour, where the mixed flour is a mixture of various ingredients according to the type of cake. Donuts, is one of 5 types of practical cake flour which are available. It Consists of a mixture of flour, refined sugar and milk powder that has been scaled so that the mixed flour of this donut flour can produce 10 pieces of donut in one process. Making the donut mixed flour on SMEs Sumber Rejeki is still done manually, takes a long time and requires 2 people. Due to these problems, tools / machines to make a donut flour dough automatically were built. By using Load cells sensors, ADC HX711 and Arduino Mega 2560, the machines can measure and mix the flour dough automatically and according to the dose given. This machine itself is composed of 3 pieces of tubes used as a filling tube of dough, the tube is given a screw-shaped lever so that the flour can go down to the weighing plate and is measured according to the type of flour. Besides donuts, this machine can also produce practical mixed flour of cake, bolu kukus, brownies and baked brownies. From the trial that has been done, the machine has the load cells error calculation of 0%. This machine can also drop off the flour on tube 1 as much as 73gr / minute, refined sugar in tube 2 as much as 26gr / minute, and milk powder in tube 3 as much as 18,9 gr / minute.
