Abstract

Heat pipes with a size of 0.0127 m diameter x 1.3 m lenght x 0.0008 m thick and absorber with a size of 1m length x 0.1 m width has been created and tested to be used as a solar collector heating element. Heat pipes are made using water as the heat transport medium and using a stainless steel mesh wick 120 as a tool that helps accelerate the flow of condensate inside the heat pipe. Testing of heat pipes will be do in two condition at an inclination of 30o , before the heat pipes selected as the heating element in the solar collector. Testing of heat pipe on the first condition is done by using 1,000 ml of hot water temperature of 100oC with the power supply of 20 watts as a heat source in the evaporator side and further testing of pipe heat was tested by direct solar radiation, this test is intended to see directly if heat pipe was made able to work in conditions that are expected. Tests are done to see the heat transfer capacity and response speed (τ) of the heat pipe. Based on testing obtained the fastest response in the heat pipes transfer of the heat contained in the filling ratio of 20% with the heat transfer efficiency of 75%.

Abstract

AHASS HCM and CPM workshops are Honda's official workshops separated by a distance of only 1.6 km located in the city of Padang. The number of customers in these two workshops is very much different, even though the HCM workshop has a better form of building and facilities compared to the CPM workshop. Research needs to be done to see the factors that influence customer interest in choosing a workshop. Performing regular service requires equipment. Tools that are often overlooked are special tools. If the workshop does not have special tools, the mechanics will have difficulty in the process of dismantling and installing or adjusting, so that the impact on the performance of the motorcycle that has been serviced. Research on the effect of the completeness of special tools during regular service at two official Honda workshops (HCM & CPM) in Padang on customer satisfaction has been successfully carried out and the results show a significant difference. The measurement of the influence of special tools on customer satisfaction is measured using the SERVQUAL method, so that service quality in both workshops can be seen. The SERVQUAL method uses several dimensions (tangible, reliability, responsiveness, assurance, empathy) which will then be translated into 16 variables as indicators to create programs that can control services oriented to customer satisfaction. The results showed that both workshops (HCM and CPM) had a gap between perception and expectations in each dimension. The average total gap for each dimension is -0.44486 for the HCM workshop and -0.2902 for the CPM workshop. This shows that the quality of service expected by customers has not yet been achieved in both workshops, but the quality of service from CPM workshops is much better compared to HCM workshops. This causes more CPM workshop customers compared to HCM repair shops.

Abstract

Engine is the main power in the vehicle and has a different performance. The differences in engine performance can occur due to different operating conditions and the fuel used. Therefore, research on the performance of combustion engines must be done to improve service to consumers, because not everyone can perform performance engine performance tests. At the time of planning the manufacture of the combustion engine, theoretical performance was calculated, but the results were different from the actual performance results on the dynamometer. Therefore an engine is tested for performance tests to get the characteristic value of the engine. The process of testing has been carried out in accordance with the Standard Operation Procedure in the relevant literature and concludes that the performance produced by the test machine shows the value of torque characteristics, the average effective pressure of the combustion chamber, fuel consumption and volumetric efficiency which is inversely proportional to the engine rotation speed . For the optimal variable engine operating conditions in this study were at 4000 Rpm with 72 Nm of torque and 30.1 Kw of power with a specific fuel consumption of 311.5 g / kWh

Abstract

Flat solar collectors with heat pipe absorber with dimension of wide 1.5 m x 2 m lenght x 0.2 m thickness and 2.87 m2 aperture area has been tested to produce hot water. Heat pipe used in flat plate solar collector, has a filling ratio of 20% which has been proven to have the highest ability to transfer heat when tested in previous studies. Testing of solar collectors with heat pipe absorber has been done during the month of April 2016 in the city of Padang by using standard ASHRAE 93-2003. The test results showed the highest efficiency obtained was 46%. To get the hot water of at least 64 ° C with a flow rate of 0,35 L / min for 5 hours, required solar radiation of 750 W / m2. Generally, during the trial obtained water output temperature collectors from 8:00 - 9:00 pm and from 15: 30 - 17: 30 is below 60 ° C, whereas at 9:30 - 15: 30 obtained collector output water temperature above 64 ° C, while the water temperature reached at the highest collector output value of 78 ° C.
