Abstract

Brake system is an important thing of vehicle. Many kinds of brake pads presents by each factory. Brake pads made of asbestos and non asbestos material. Each of them have excess and lack. This research aims to know the performance of each type of brake pads so that it can show the excess and lack of each type of product. As user, we have to choose a product which will be used in our vehicle cleverly.The research be done by giving variations in load of brake and weight of rider at a constant speed. The load of brake used spring with the variation are 2 kg, 3 kg and 4kg. While, weight rider are varied with 54 kg and 111 kg.Research result shows that increasing load of pull brake led to increasing the value of worn out and a decline in the braking time, while increasing weight of the rider causes an increase in the value of worn out and braking time at all types of brake pad products. In dry condition, the lowest wear is 1,37x10-4 mm/second in non asbestos pads and the highest wear is 3,088x10-5 mm/second in asbestos pads. While, the smallest braking time is 28,79 seconds in asbestos pads and the biggest is 64,26 seconds in non asbestos pads. In wet condition, the lowest wear is 2,422x10-5 mm/second in asbestos pads and the highest wear is 7,716x10-5mm/second in non asbestos pads. While, the smallest braking time is 29,46 seconds in non asbestos pads and the biggest is 62,71 seconds in asbestos pads.

Abstract

The long term purpose of this research is to obtain the high quality renewable biogas that can be used as fuel for internal combustion engines to drive an electricity generator as energy diversification efforts in the area of small sustainable islands. The specific target expected to be achieved is a method/technique for absorbing impurities contained in biogas, especially CO2 component. The study was conducted to reduce the level of CO2 in biogas using NaOH solution. The mass flow rates of biogas employed were 2, 4, 6, 8 and 10 l/min. The biogas was then tested using an engine to see the effect CO2 on the engine performance at several rotations, i.e. 1500, 2500, 3500, and 4500 rpm. The results show that the torque increases by 21.3% for biogas B2 compared to the unpurified biogas. For biogas B4, the torque increases by 19.1%. While for biogas B6, B8, and B10, the torques increase by 14.9%, 12.8%, and 8.5% respectively. For biogas B2, the SFCE decreases by 33.4%, for biogas B4, the SFCE declines of about 22.7%, while for biogas B6, the SFCE declines by 17.9%. The SFCSs also decline by 13.9% and 8.5% for biogas B8 and B10.

Abstract

The purpose of this study was to obtain handling connection type in use as door panels, roofing sheets, walls and floors. Therefore, the tests performed are fastening test and abrasion test. The technique of making wood composite is using hand lay-up technique. Constituent material of board composite is using pandanwangifibers with length variationsare 15 mm, 20 mm, and 30 mm with volume fraction variations are 20% and 30%, and 5% Sengon tree saw-dust is used as the filler. The results showed that pre-drilling with fastener sizes # 6, # 8 and # 10 is 3.5 mm, 4 mm and 4,5mm. The distance between each fastener depends on the fastener head itself, ie fastener # 6, # 8, and # 10. Critical distance between the edge of the fastener has a significant effect on fiber length and volume fraction. The highest value is shown on 15 mm of the fiber length and 20% of volume fraction with the value 3.29 mm, and the lowest value is shown on 15 mm of the fiber length and 30% of volume fraction with the value 2.74 mm.

Abstract

The electrification ratio in Indonesia has only reached an average of 95.35%, but this achievement has not been evenly distributed, there are regions with high electrification and some that are very low. The electrification ratio in NTB for example has only reached 84.11%, therefore in NTB, the community still lacks electricity. Meanwhile, in fact the NTB region has very potential energy sources, such as solar energy, water energy, wind energy, marine energy, geothermal energy, biomass energy and biogas / syn-gas. However, the utilization of various energies has not been maximized. Based on this situation, this activity aims to introduce and promote the use of renewable energy sources. This community service activity was carried out at SMAN 1 Alas, West Lombok in the form of counseling and demonstration of renewable energy producers. In general, this activity ran well, safely and smoothly and got an encouraging response from the participants, and also got support from the community of SMAN 1 Alas and their teachers.

Abstract

The development of science and technology today is very rapid and develop in various sectors, that one is in engineering material sector, specifically composite material . One method of composite formation is powder metallurgy method. Powder metallurgy is a metalworking technology in which components are manufactured from metal powders. This study aims to determine the effect of holding time sintering and mixing composition on hardness and macro structure observations. The material used in this study was aluminum waste that came from the rest of the window cutting. The specimens were made using powder metallurgy method. In this study the variations used were the sintering holding time of 120 minutes, 180 minutes, 240 minutes, composition variations of 80% Al : 17% Sic : 3% Glass, 80% Al : 14% Sic : 6% Glass, 80% Al : 11 % Sic : 9% Glass, 80% Al : 8% Sic : 12% Glass. Some control variables are grain size 100 mesh, mixing 15 minutes, compacting 7 tons and sintering temperature 600oC. The results obtained are the highest hardness value is found in the specimen with a sintering temperature of 600oC with a sintering holding time of 240 minutes at a material composition of 80:17:03 which is 90.33 HRF. The macro structure observations showed that there was a smaller porosity in the specimens with high hardness values. The results of the overall mechanical properties test show that the variation of the sintering resistance time has an effect on the specimen which will give time for the formation of stronger bonds between particles. While the variation in the composition of the material with SiC reinforcement the more the percentage given, the greater the composite hardness.

Abstract

The problem of waste is a problem that requires serious handling, especially inorganic waste, where this waste cannot be destroyed by nature in a short time. Indonesia itself does not have a special treatment for this used clothing waste. Used clothes that are still fit for use can be resold or donated to those in need, but not every second-hand clothes can be reused so that used clothes are only thrown away which can cause pollution to the surrounding environment. With the increase in the human population in the world, the needs also increase, such as the need for food, clothing and there is also an increasing need for buildings. Panels are one of the most widely used building materials, especially for insulating walls in house buildings. One type of panel is a lightweight concrete panel. The purpose of this study is to utilize used clothing waste as a part of lightweight concrete composites where the fibers of used clothing waste are utilized as reinforcement for lightweight concrete composites and to determine the effect of adding used clothing waste fibers to the compressive and bending strength of the lightweight concrete. The variations that will be used are 0%, 0.3% and 0.7% with the size of the mold for bending, which is 160 mm long, 40 mm wide, 40 mm thick. while for the compression test mold is cylindrical in shape and has a height of 300 mm and a diameter of 150 mm. The results of this study indicate that there is an increase in strength in the compressive test from not using fiber or 0% of 4.42 N/mm2 , using fiber with a variation of 0.3% of 5.47 N/mm2 and fiber with a variation of 0.7% of 6.13 N/mm2 . The bending test shows a decrease in strength from variations of 0%, 0.3%, 0.7% to 3.65 Mpa, 3.376 Mpa, 2.6 Mpa.
