Abstract

The study was conducted with a direct current DC motor ignition system circuit object with a 12 Volt battery source. This experiment compares a standard coil and a Groundstrap coil. The engine is varied with 2000 rpm, 5000 rpm and 8000 rpm. Engine speed is measured using a tachometer. Sparks are measured using the bar and the color of sparks is captured using a digital camera. Data retrieval is done with 3 replications. The data is averaged and a statistical test is performed. The results showed that the use of Groundstrap coil with wire variations and the dimensions of the coil affect the length of the spark jumps and the color of the sparks. There is a significant difference in the length of the spark jump between the standard coil and the Groundstrap coil. Standard coil lengths are longer out of focus than shorter focused Groundstrap coils and more blue sparks.

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 solar collector is a device that serves to collect solar radiation and convert it into useful energy of calories. Solar water heater collectors are heat exchangers that convert solar radiation energy into thermal energy in water. This research is done by modifying the existing pipe in the solar collector, wherein the pipe is given a barrier in the form of a spiral stainless wire with the difference of size that is 0.5 cm, 1 cm, and 2 cm. This study was conducted for nine days. The result of this research proved that the distance of the spiral barrier in solar collector has an effect on efficiency, the smaller spiral barrier distance makes the collector efficiency increases. It’s caused by the flow of water fluid in the pipe collided with the spiral shaft and formed following the spiral groove so as to increase the water temperature difference higher, with the higher water temperature difference then the value of solar energy useful solar collector increases. The increased heat energy is useful to the efficiency of solar collectors, where the efficiency of collectors will increase as well. The discharge flow also affects the collector efficiency, the more greater the rate of water flow, the collector's efficiency will decrease. It’s because the residence time of water in the heating pipe is shorter and the mass flow rate is greater. Furthermore, the value of solar energy useful solar collector is getting down so that collector efficiency is getting down anyway. The maximum collector efficiency occurs at a 0.5 cm spiral barrier distance with 1 liter / minute water discharge of 24.72%, while minimum efficiency occurs at 2 cm spiral barrier distance with water discharge of 3 liters/ minute that is 11.75%.

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

This study aims to minimize the occurrence of air pressure losses in the airflow pipe. The research was carried out by giving the blades varying 5, 6, 7 blades with an angle of 40˚, 50˚, 60˚ in the pipe with full valve, valve openings, ½ and ¼, measurements were made at 3 measurement points using a manometer U in place it in the pipe before passing the propeller and after passing the propeller there are 2 measurement points. The results showed that the smaller the number of blades with the smallest angle, the greater the pressure produced, and the more the number of blades with the largest angle, the smaller the pressure produced

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 influences 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.

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.
