Abstract

The battery cell damage detection tool solves the problem of using a wet type battery (lead acid), most battery services analyze cell damage by cutting the battery cover with the awakening of this tool analyzing battery cell damage without having to cut the battery cover and detecting each cell so that it saves processing time checking the battery and analyzing the damage. This type of design is in the form of an experimental engineering method that aims to determine the damage to the battery cells and the interconnections between cells. The results of this experiment aim to shorten the time and effort when sorting used batteries quickly and without damaging the battery cover

Abstract

Indonesia is one of the largest rice producing countries in the world (6,905,612,600 tons with a harvested area of 1,344,552,400 Ha). Rice is a national strategy commodity and is consumed by most of the Indonesian population. Rice consumption continues to grow along with population growth. Therefore, rice production must also increase according to the demand for rice needs. The increase in rice production has generally been successful, but the added value obtained has not been fully enjoyed by farmers, especially the high yield loss. The purpose of this research is to make/build a rice thresher machine with a capacity of 100 kg/hour and to get a value for the production capacity of a rice thresher machine with a 6.5 HP machine. This research uses the Research and Development (R&D) method or experimental-based development research, namely by developing a rice thresher machine (thresher). The thresher design used Solidworks 2014 software with a length of 730 mm, a circumference of 370 mm in diameter and a threshing tooth length of 8 cm. The threshing cylinder is made using a shaft iron material with a thickness of 1 inch, 9 screw threads with a diameter of 9 mm circumference, a strip plate with a thickness of 2 mm iron and concrete iron with a length of 8 cm. The test results of the rice thresher machine produced 63 kg/30 minutes with a 6.5 hp engine with a capacity of 3600 rpm with a gas opening of 3/4 and fuel consumption of 1 liter/half hour.

Abstract

Students who carry out practicum at the Aerodynamics Laboratory of Mechanical Engineering, State University of Surabaya have a smoke generator that is still simple, where the tool still has shortcomings in producing thick and constant smoke. The design of this tool uses the Research and Development (R&D) method with the analysis carried out covering the design of the tool, the heater used and the material. Trials of several heating devices and materials that have been carried out such as water heaters using liquid paraffin and dry ice. The second experiment was using a hairdryer using liquid paraffin, VG glycerin and VG+PG glycerin, the third experiment using flat nickelin wire with liquid paraffin, VG glycerin and VG+PG glycerin and the fourth experiment using coiled nickelin wire using liquid paraffin, VG glycerin and glycerin. VG+PG. Experiments on heating devices and materials were carried out by dripping and also partially soaking, except for heating water with dry ice by adding hot air to dry ice. From the experiments that have been carried out, the maximum heating device in producing as soon as possible is using a coil of nickelin wire with liquid paraffin. The results of the development and engineering of the research tool decided to use 3 coils of nickelin wire with a length of 120 mm, a diameter of 10 mm with a resistance per nickelin of 3.5 Ohm. For the power supply, the adapter uses an AC input of 220V DC output of 24V 10A and uses liquid paraffin as a liquid to be evaporated, because it does not cause corrosion of tools or wind tunnels. This tool works by evaporating liquid paraffin that is submerged in a coil of nickelin wire with a horizontal hanging position. It takes 3-5 minutes to get production fast which is good. From the smoke generator test results, this tool can be used for 10 minutes per rake in the wind tunnel in the data collection process.

Abstract

Fluid mechanics is a scientific discipline, which is part of the field of applied mechanics which studies the behavior of liquids and gases in a state of rest or motion. Fluid mechanics can be divided into fluid statics, fluid kinematics, and fluid dynamics. Fluid dynamics are fluid mechanics which study fluids in motion, especially liquids and gases. Fluid dynamics has a wide range of applications. Examples are used in calculating forces and moments on aircraft, mass flow rates of petroleum in pipelines, and forecasting weather patterns. Fluids are substances that can flow which have small to invisible particles and they can easily move and change shape without mass separation. Flow visualization is used to make the flow pattern of fluid (one of which is air) visible in order to obtain accurate data. The purpose of this research is to create a smoke generator that can spray smoke continuously. The method used in engineering is to vary the distance between the output pipes (tubes). There are three variations of rake used with each distance between the output pipes (tubes) of 60 mm (5 pieces), 42 mm (7 pieces), and 30 mm (9 pieces). The diameter of the outlet pipe (tube) and the main pipe (manifold) are made the same. The results of this engineering show that with variations in the distance between the output pipes (tubes) on the rake, different visualization results are obtained. In the 9 output pipe variations, the smoke output (streamline) is better than the other two versions, it can be seen from the visualization of the flow at the stagnation point and the flow is deflected to the upper and lower surfaces. While the visualization of the flow behind the vehicle there is not too much change because it does not vary the angle of the diffuser.

Abstract

Actually, this spring is also discussed in physics, wherefrom the spring we can calculate the increase in the length of the spring based on the given load. Spring is an elastic object used to store mechanical energy. Springs are usually made of steel. There are several spring designs. In everyday usage, this term refers to Coil Spring. Springs are also found in motorcycle suspension systems. In motorcycles, springs have the function of absorbing shock from the road and wheel vibrations so that they are not transmitted directly to the vehicle body. In addition, springs are also useful for increasing tire grip on the road surface. In the teaching and learning process in physics courses, there are still obstacles, namely, there is no vibration practicum tool, from the desire to know the design of the tool, and to know the results of the tool's performance, the author can apply the results of the lectures that have been taken in the previous semester. This design aims to determine the design of the tool and the results of the performance of the spring stiffness test equipment. The design of the trainer uses the Research and Development (R&D) method or experimental-based development design. The spring stiffness test is a test of the change in the length of the spring when it is given a certain load. This study aims to design, manufacture and test spring stiffness test equipment. In the design process, it is necessary to calculate the frame, function, and type of material to be used. The analysis carried out includes determining the electric motor, determining the material used, knowing the design of the tool, and knowing the results of the performance of the tool later. After analyzing the work of the tool and analyzing the test results, a conclusion will be obtained that can be drawn based on the existing data.
