Dispensers have an important role in providing adequate drinking water for needs and can be placed around where we work. The purpose of this research is how to design and make an automatic dispenser system based on Arduino Uno and it can work well when filling the glass when the glass is placed. This research was conducted by coding using Arduino IDE 1.0.6 software to program Arduino Uno to control servo motors and ultrasonic sensors. The results of this study indicate that the automatic dispenser can work to fill glasses from a distance of 5 cm to 0 cm and open the dispenser faucet 1 cm. From the manufacture of this tool it can be concluded that this tool works well, in accordance with its purpose to make it easier to take water, the automatic dispenser is driven by a servo motor with a wire attached to the side of the dispenser lever, the control system uses Arduino Uno. Suggestions can be given so that this tool can be developed. Another suggestion for development is that so that the automatic system of this tool can work properly, the placement of the sensor must be in the right position so that the glass plate can be filled properly, it is better to turn on the Arduino uno by using a switch.

The development of building construction always requires materials, machines (equipment) and work methods to increase the efficiency of work completion. Sand material which is the main building material in the manufacture of a construction structure. The work method for separation is generally carried out by sieving which aims to obtain uniform sand sizes. In this study, a sand sieving machine was designed using the translation method of shaft rotary motion. Procedures in the design of the sand sieving machine are carried out by collecting initial data and field requirements regarding the sand sieving machine, determining the effective mechanism of the sand sieving machine, analyzing the elements of the sand sieving machine, and determining the design of the sand sieving machine. The working system of the machine is designed to use an electric drive motor, a pulley belt transmission system is used to reduce the rotation of the motor, then the eccentric drive shaft is used to rotate the crank which in turn moves the pusher rod so that the sieve moves translationally. The frame design of this sand sieving machine uses square profile steel 40 mm x 40 mm with a thickness of 2 mm. The box profile steel is designed so that it becomes the support of several machine components including the sieves, the dimensions of the frame are 100 cm long, 70 cm high and 70 cm wide. The calculation results obtained that the shear stress that occurs on the shaft is smaller than the allowable stress. The sieving machine design uses a belt transmission and two pulleys to reduce the motor rotation to 509 rpm, this rotation is then converted into translational motion to move the sieve with a speed of 2.34 m/s.

The phenomenon of the movement of fluid flow across an object plays an important role in terms of transportation. Different body shapes will produce different fluid flow characteristics and greatly affect the function of the body shape, so it is important to know the characteristics of fluid flow, so that the factors causing losses in a construction that are not in accordance with the natural properties of the fluid can be identified. If the drag is large can be reduced, the energy needed to move can be reduced and save fuel. the use of numerical methods is a way of studying flow characteristics that is relatively inexpensive with a scientifically justifiable level of accuracy. The problem of this study is how the characteristics of the fluid flow to the forces that pass through the square cross section. This study uses a square geometry test model and a single splitter plate geometry test. The research was carried out by computational methods using Ansys FLUENT CFD software with the Realizable k-ε turbulence model. The results showed that the use of a splitter plate resulted in a decrease in Cd, -CPb values and an increase in speed (u). This indicated that the use of a splitter plate could reduce resistance and pressure and expedite the distribution of fluid flow. and there is an increase in the Cl value parameter, this is due to the enlargement of the wake. From this study it was found that the use of a splitter plate was good in reducing Cd values, this is in accordance with the literature Kata kunci: Ansys fluent, CFD, fluid, Reynolds, drag coefficient, pressure coefficient, lift coefficient

In the industrial world, the development of material technology is growing rapidly. There is an increasing demand for materials with certain properties such as perforated composites. The consideration of perforated composites is an important parameter in the design of composite components. The purpose of this study was to determine the tensile stress and strain characteristics of hollow CFRP composites. The research method used is to analyze the tensile test using abaqus software, the tensile test analysis is carried out with 3 variations in the diameter of the hole (2 mm, 4 mm, and 6 mm). From the tensile test simulation results, it is found that the highest stress occurs in the 6 mm diameter composite with a maximum stress value of 180.4 N/mm², and the lowest stress occurs in the 2 mm diameter composite with a maximum stress value of 102.6 N/mm². The highest stress and strain that occurs in each specimen is located on the edge of the hole perpendicular to the direction of the force, the stress and strain increase based on the diameter of the hole in the composite, the larger the diameter in the composite, the greater the stress that occurs..Keywords: Tensile test, CFRP composite, abaqus software
