Lumintang, Romels Cresano Apelles
In this study, the materials used as reference are carbon steel and the copper alloy. Corrosion process is done by soaking the material in the test environment and H2SO4 solution of sea water that has collected in a glass aquarium in order to circulate properly with the aid of a pump. The length of immersion performed for 1 hour 3 times as much as 3 hours of immersion and immersion for 3 times. The purpose this study is to determine the corrosion that occurs in the material of carbon steel and copper alloys. Weight loss due to corrosion is closely related to time, in other words increasing immersion time, the greater the weight loss that occurs. The rate of corrosion test results conducted with a time of 1 hour, the average value obtained for the specimen I in of carbon steel and copper alloys in seawater solution is 0,105 mils / year and 0 mils / year. While in the sulfuric acid solution is 0,162 mils / year and 0,028 mils / year. And the rate of corrosion test results conducted by 3 hours, the average value obtained for the specimen I in of carbon steel and copper alloys in sea water solution and sulfuric acid is 1,350 mils / year and 0,015 mils / year. While in the sulfuric acid solution is 1,400 mils / year and 1,306 mils / year.

Filter in this research is interpreted as screening of undesirable frequency component in order to depressed it as small as possible to produce the changes of magnitude of response signal. The filtered vibration signal is in a form of the Random Signal Excitation which is generated in MATLAB Version 6.5. The signal is filtered by using Filter Chebyshev Type II. Simulation conducted repeatedly from 10 to 100 times excitation. Magnitude of Response Filter is obtained after simulation. Result is compared to its initial and expressed in the form of different percentage of magnitude between the mean of Magnitude of Response Filter because of applying Random Excitation Signal to the Excitation of Signal Impact from 10 to 100 times. Maximum different percentage of highest magnitude occurred in the simulation of 10 times excitation (57%). While the Minimum occurred in the simulation of 50 times (32%).

Interchangeability of motorcycles spare parts is needed in case of difficulty obtaining the original in the market. This research aims to develop the software model to optimize output shaft diameter and to compare the torque forwarded to rear sprocket of a motorcycle. The software develop using MATLAB R2010. Optimization is performed by making objective function variables with constraints and stress deflection resulted it the shaft loaded. Optimization is carried out with the conditioning in the highest speed transmission, that is : 1 840rpm, 2 1300rpm, 3 1800 rpm to 4 3000 rpm, and 5 3500rpm. Results obtained for a 8426.41 Nm/s power standard motorcycle is shaft diameter Do=12mm and Di=1.04mm. Finally, the software calculate the inertia force in order to obtain the stress Results showed that presence of shaft diameter optimization, load balance as well as engine power was still able to be borne on the optimum diameter. With the change of the diameter of the shaft diameter of the bearing replacement is done it is the same with the outer diameter of the shaft. Key word : rear wheel axle, Optimization, Do, Di.

PERANCANGAN KONVEYOR RANTAI KAPASITAS 8 TON PER JAM
Rante, Angrian
Tangkuman, Stenly
Rembet, Michael
Conveyor is an auxiliary equipment in a production process. The main component of a chain conveyor is chain . This chain is driven through a sprocket which is connected to an electric motor through a reduction gear. Process of designing a chain conveyor required several parameters that are : the characteristics of the transported material, conveyors geometry, conveyors capacity and conveyor speed. Design resulted in chain dimension and the required motor power. Comparing the design to the existing conveyor as a case of study, it was found that the electric motor used is larger than necessary which in turn that the speed of the chain there can still be improved in order to increase production capacity. Keywords : Design , Chain-Belt Conveyors, Conveyor Capacity

PENGARUH PENCAMPURAN BROWN GAS KE BENSIN PREMIUM UNTUK MOTOR BENSIN YANG DIPASANG PADA SEPEDA MOTOR SUZUKI SMASH 110 CC
Bawiling, Desly Theo Daud
Gunawan, Hardi
Gede, I Nyoman
This research is aimed to determine the effects of brown gas mixed with gasoline on fuel consumption of a Suzuki Smash 110cc. Data taken in this study is the fuel consumption of the vehicle on different gear ratio, and velocity of the vehicle within a distance of 2.5 km. Analyzing is done on gear ratio-1 at 10,15,20,25,30 km/h, whereas on gear ratio-2,3 and 4 at 20, 25, 30, 35 and 40. The result of observations and computation shows fuel consume rate gear ratio-1 is 266,4; 349,3; 455,1; 562,6 and 697,5 gr/hr on gear ratio-2 is 359,2, 410,9, 439,0; 545,9 and 648,9 gr/hr, on gear ratio-3 is 296,9; 295,8; 408,6; 494,4 and 624,5 gr/hr, on gear ratio-4 is 201,9; 249,4; 412,0; 330,8 and 538,0 gr/hr with the speed of 20, 25, 30, 35 and 40 km/h consecutively. The conclusion is the higher the speed of motorcycle, the greater the rate of consumption. It was found that the testing is executed in the range of engine speed of 2136 to 6182 rpm. These results demonstrate that the motor cycle is more efficient if using gears ratio-4 at a speed of 20 km/h to 40 km/h. Key Word : fuel consumption , brown gas, gasoline engine, Suzuki Smash 110cc.

enMost refrigeration system using synthetic refrigeration R-12, R-22, R-134, and R-600a. Synthetic refrigeration has many good characteristics, among others, not easy to burn, no poisoned, and easy to get. However, synthetic refrigeration has negative effects for environment. It can broke our ozone layer and make global warming. The using of hydrocarbon as refrigerant is one of the solution to handle these problems. An experiment is done using unit SN 1016-1-149-1 cooler machine in mechanical laboratory in Sam Ratulangi University in Manado. Data is taken after completed the unit preparation. Analysis is done by comparing the cooling rate beetwen R-12 and MC-12. The average cooling rate of R-12 cooler are and respectively using air and water cooling media. In a serial of three experiments, The average electric current used in the unit are 0,75 A and 0,74 for air and water media respectively using of R-12 and Of MC-12 refrigerant . The average cooling capacity of MC-12 is . Then, faund that MC-12 cooler capacity by air and water media is bigger than R-12 cooler capacity by air and water media. Key words : R-12, MC-12, Cooler Speed

Lubricating oil available in a wide range which is offered consumers through the promotion in order to convince consumers that the product is the best. This study aims to determine preferences of consumers in the selection of motorcycle 4-stroke type lubricating oils using Analytical Hierarchy Process (AHP) method. From the analysis using the AHP based on criteria, it shows that durability is ranks the first with a weight value of 0.5034, following with stock availability (0.5019), price (0.4248), and recommendations of manufactorer coming last (0.3840). As for the preference of alternative lubricating oil, analysis base on brand of motorcycle it shows that Yamaha with Yamalube 7.5% all criteria, Honda with Yamalube of respective value 4.77% and 4.37% on criteria recomendation of manufactorer and price, Enduro 3.16% the stock availability, and federal 3.08% for durability. Suzuki of Yamalube which is value of 3.43% and 3.05% on criteria recommendation of manufactorer and price, Enduro ​​respectively 3.56% and 3.43% to criteria stock availability and durability. Kawasaki on Enduro with 43.76% and 26.85% to the price and stock availability, Top-1 27.17% and 31.28% to recommendations of manufactorer and durability. Keywords : Preferences, Oil Lubricants, AHP, Criteria
