Abstract

Flame is a phenomenon of rapid oxidation of an element in a physical and chemical reaction process that produces heat, light, and other chemical products. Flame testing aims to quantify the presence of a particular element through the emission spectrum of each element. In addition, the physical characteristics of the fire object were also observed. ImageJ software is one of the practical supporting applications that is often used for observing flame objects specifically in the fields of chemistry, physics, and energy. Experimental results have shown the level of accuracy of object dimensions and spectrometry with an accuracy rate of 97%. Differences in measurement ranges are often triggered by the image of the object and the foresight of the researcher.

Abstract

Wood chipper machine is a tool used to crush wood waste into powder (particles). This study aims to determine the effect of the distance between the blades and the hopper angle due to wood chipper machine performance. The distance between the blades was varied by 2 mm and 3 mm. The hopper angle was varied by 45o, 50o, and 55o. Measurement of sengon wood particles is done by using wire-mesh with sizes of 1.19 mm, 0.25 mm, and 0.15 mm. The result of the study show that there is an effect of the distance between the blades and the hopper angle due to wood chipper machine performance.

Abstract

The contact between ball and tennis racket is a collision phenomenon. The ball exerts a force on the racket which causes deflection. This study aims to obtain the deflection characteristics of a tennis racket due to ball contact. The research was conducted by experiment with Kinetic brand rackets. The racket is clamps on the grip. The ball used is Nassau brand with 0.058 kg of mass. Free fall is arranged 1, 2 and 3 meters heights, with 3 hitting points on racket string. The deflection measurement uses the pen method at 5 points on racket frame. Five points are arranged sequentially from the grip with 6 cm distance. Data collection was carried out with 3 repetitions to get average value. The deflection was measured using a caliper with 0.01 mm accuracy. The results show that the deflection has a linear characteristic and depends on the momentum of the ball.

Abstract

The electrical system Auxiliary Power Unit on the Boeing 737-500 aircraft often experiences operational failure due to damage to the components in the system, this incident causes significant operational losses so that an appropriate maintenance method is needed to eliminate the factors that cause failure in the Electrical system Auxiliary Power Units. The purpose of this study is to plan preventive maintenance activities on the Electrical Auxiliary Power Unit system so that part damage that causes failure can be handled properly. The reliability method is calculated using the Weibull probability distribution so that the critical operating time limit is obtained on the Electrical Auxiliary Power Unit system. From the calculation results, the critical operational limit for the Electrical Auxiliary Power Unit system is 271 flight cycle with the main damage being the start relay component, with maintenance activities in the form of inspection, repair, testing and cleaning activities.

Abstract

Sand is an important material in building construction for residential houses, places of worship, offices, educational facilities, and other buildings. Sand generally consists of sand mixed with gravel and stone. An automatic sand sieving machine makes separating rock gravel from sand easier. Making an automatic sand sieving machine aims to get better quality and cleaner sand screening results. This sand sifter machine is made to prevent the entry of gravel in the sieving process. In addition, the sand sieving process can be more efficient and effective. The automatic sand sieving machine has dimensions of 100 cm long, 70 cm wide, and 80 cm high. The test results of the sand sieving machine can sift sand with a capacity of 5 kg in 15 seconds and a sand capacity of 10 kg in 32 seconds.

Abstract

Hardenability is the ability of a material to harden to a certain depth utilizing heat treatment to form martensite upon cooling to achieve a certain hardness. The hardness of a metal, especially steel, can be modified without adding alloying elements and is done by heat treatment. Steel's hardenability value is strongly influenced by the carbon content (carburizing) in the steel structure. Increasing the hardness of a material can be done by adding carbon to the object's surface during heat treatment. The Rockwell Hardness Test method measures the surface of the hardness. The test results on the specimens showed that the carburizing process of each specimen increased the hardness of the surface of the specimen. The distribution of hardenability values ​​is close to a linear line, namely the heat treatment temperature 900oC.

Abstract

The coastal area of ​​Madura has many fishing boats or fishing vessels of various types and sizes. The construction of traditional ships is carried out by groups of workers or traditional shipyards which are not permanent, technological readiness is still minimal, and the workforce is very limited. Especially in traditional shipyards in the coastal area of ​​Madura or throughout Indonesia's coastal areas, which still rely on skills from generation to generation, so it is difficult to achieve the ship size desired by the customer, even the deviation of the size in tons can reach 25 percent. This situation shows the weakness of the technology applied in the traditional shipbuilding industry. Therefore, the technology of dowel making machine for making wooden dowels is carried out 3 in 1 with the function of shaving wood, cutting wood as desired and sharpening pegs or wood. All work is done in one machine which can be done automatically by setting the desired peg size and running with a microcontroller system. Tests have been carried out on a 3 in 1 dowel machine using 2 motors, the average time is equal to or more than 1 minute/1 piece of peg. Testing the tool using 1 motor obtained an average time of less than 30 seconds to produce 1 wooden peg.
