Abstract

A matic motorcycle 110 cc is one of kinds of motorcycle that many used by the modern people, especially for the narrow streets with high level mobility. One of aspects to beconsidered in this vehicle design is a level of comfort and safety in reducing the vehicle due to environmental conditions. The purpose of the research is to get the characteristics of shock breakerin matic motorcycle 110 cc with three motorcycle brands due to road profiles. The research was conducted with road profile model (flatten, slightly wavy and wavy) at Rpm speed (1700, 3500, 4000 and 5000). Vibration was calculated based on the speed of circle engine (Rpm) using vibration’s meter. Measurements were done at 3 points in the shock beaker, rider and passenger with 60 seconds 20 seconds. The results showed that the greater the engine speed (Rpm), the vibration tends to be smaller, whereas the smaller the engine speed (Rpm), the vibrations tend to large.

Abstract

The study was conducted with a pyrolysis experiment where temperature variation of 250oC, 350oC, 450oC, and 550oC and tire sample mass of 300 gram. The heating temperature comes from an electric heater equipped with a control system. The temperature was measured using K type thermocouple. The residence process was carried out for 120 minutes measured using a stopwatch. The tire and char sample volume were measured using measuring cups and the sample mass was measured using the scales. Tests on char quality characteristics include flame, coal temperature, flame time, and ash residue. The results showed that the higher the process temperature in pyrolysis, it affects char characteristics on the rotary kiln. The percentage of char mass losses tends to increase with the high pyrolysis process temperature. Char shrinkage factor tends to decrease as the percentage of mass loss increases. Char porosity tends to rise as the percentage of mass loss increases. The percentage of blue color on the char flame tends to rise in accordance with the addition of the percentage of mass loss and vice versa the percentage of red color on the char flame tends to decrease. The combustion temperature of char combustion tends to increase according to the high temperature of the pyrolysis process. Coal char's flame time tends to increase as char porosity increases. The ash of combustion yield tends to decrease as the percentage of mass loss increases.

Abstract

In this study modifications to the cutting knife and rotational speed were carried out. With blade variations of 2mm, 3mm and 4mm and rotational speeds of 300, 900 and 1500 rpm. After the research process is carried out, the noodle product tests include the length of the noodles, thickness, and elongation values. For testing, the length and thickness of the noodles used a measuring device ruler and calipers and testing the value of elongation was done by tensile tests. The results of the study showed the percentage shrinkage of 0.0% noodle dough weight. This shows the test equipment is working optimally. The faster the rotation of the motor the difference between long and thick noodles tends to increase. This shows that the rotation speed has an influence on the performance of the flattening machine and noodle dough cutter. The faster the motor rotation, the elongation value of noodles tends to decrease. This is due to the rotation speed of the motor that affects the occurrence of broken noodles. The greater the size of the noodles the risk of breaking up the noodles decreases. The faster the motor rotation, the greater the capacity produced.

In this study, variations in pressure and adhesive were carried out, with variations in pressure of 4cm, 4.5cm, 5cm and variations of adhesives including two variations of sieve raw material 10gr, 20 gr, 30 gr, 40gr, and 100 gr, 110 gr, 120 gr, 130 gr. sieve raw material. After the research process, the briquette fire temperature test was carried out including the heating value of the briquettes, the cooking test of 500 ml of water on each briquette variation. To test the calorific value in each briquette variation, type K thermocouple measuring devices are used. From the results of the study, the best flame temperature was found in coarse filter coffee briquettes with 110 gr adhesive variation and briquette size 4.5 cm, reaching temperatures of 602ºc and testing 500 ml of water. the resulting water heat reaches 68.9ºc during 00.05.20. From the results of research coffee briquettes waste briquettes have a very high fire heat level

Abstract

Technology developments in the maritime sector, especially shipping has experienced a significant increase. One of them is the technological development of ship parts such as a bow. The aim’ of this development is to determine the shape of the ship's bow that is most effective when moving. The study was conducted using miniatures resembling 7 bulbous forms. Dimensions of the pool are 150 x 30 x 8 cm, type of fluid used is seawater without currents. Ship's propulsion uses 6-volt dynamo. Travel time is measured using a stopwatch by taking data 3 times in each form of a bow. Data analysis is based on the average inhibitory coefficient (Cd) value that occurs. The results of the study show the shape of the bowel influences rate of speed and drag coefficient of the ship. The oblique direction I produce a drag coefficient (Cd) of 0.27 when the ship moves, so speed and travel time are more maximal than the other 6 bow directions.

Abstract

The transportation system generally prioritizes comfort and safety in terms of driving. To support this, a good suspension system is needed. Leaf springs are one of the suspension systems found in vehicles that function as vibration absorbers, as well as supporting vehicle frames. So it is necessary to do research on leaf spring spacing. To find out the distance of leaf spring deflection. This study focuses on the distance of deflection and the frequency of deflection on leaf springs, presumably there are characteristics of leaf spring spacing. The purpose of the study was to determine the distance of leaf spring deflection. From the results of the research carried out the results obtained The greater the static load that is given gives the effect of changing the shape of the plate that triggers a long change in each plate sheet. The biggest value of length change that occurs on the plate no (1) variations in the load of 15 kg which is equal to 99 cm.

Abstract

The research was conducted with experiments, with variations in the corners of the foot kick inside and outside. The angles used are 250and 350 w with foot swings of 450, 600 and 750. The result of this study showed that the greater the angle of the swing leg then the result of the leg swing against the ball would be faster the rate of the ball because the angle of a large leg swing would produce a large force or force. While the angle of the intersection of the foot is greater the angle of the resulting deviation will be the greater angle. The outer and foot kicks in differ as they kick using the straight leg of the ball will go straight by the pace of the balls whereas if using the outer foot will turn his ball or stray towards the specified kick.
