Abstract

The folding gate is a middle frame flanked by cross bars on the back of the shop door which has a higher level of strength than the body of the door and has better security. The U folding profile is made by a plastic deformation rolling process in which the plate is passed between the pressing roll and the sliding roll. Flat plates are used from the base material of metal plates with varying plate thickness where the metal forming process uses a cold working process. Factors that affect the results of rolling are roll dimensions, machine capacity, roll pressure lever settings and others. The thickness of the plate that can be rolled by the machine, the amount of force exerted on the roll gap, the evenness of the roll surface both vertically and horizontally and the alignment of the roll gap. The thicker the material with a large pressure spacing can affect the forming process so that it enlarges the largest angular deviation of 0.761 mm at a pressure spacing of 0.0 mm. A thicker material with a large pitch can enlarge the wing opening so that both wings bend imperfectly making the height deviation increase by 18.58 mm at a pitch of 0.0 mm. Thinner material with a large press distance at the start of the roll affects the flange width so that the rolling force exerted on the contact gap between the roll and the workpiece side is unbalanced. Get the largest size b- (8.030 mm) 0.0 mm pressure distance and b+ (7.843) 0.15 mm pressure distance.

Abstract

This paper deals with the exhaust emission of plastic fuel on single cylinder diesel engine. The objectives of this research are to analyze the fuel consumption and the emission characteristic of a single cylinder diesel engine that are using plastic fuel compared to usage of ordinary diesel that are available in the market. This paper describes the setups and the procedures for the experiment which is to analyze the emissions characteristics and fuel consumption of diesel engine due to usage of the both fuels. The experiment used diesel engine with no load which means no load exerted on it. Detail studies about the experimental setup and components have been done before the experiment started. The obtained data indicated that the diesel fuel is better than waste plastic disposal fuel in term of fuel consumption, emissions of carbon monoxide (CO) and emissions of carbon dioxide (CO2). The successful of the project have been stated which is engine is able to run with plastic fuel but the engine needs to run by using diesel fuel first, then followed by plastic fuel and finished with diesel fuel as the last fuel usage before the engine turned off.

Abstract

Water is a natural resource that is very important for life in the world, especially for humans and other living things. There are few areas in Indonesia that have unsuitable water due to water pollution and limited fresh water source. Distillation is an effective way to produce clean water that is free from impurities in the form of small solids, germs and bacteria. One type of distillation systems is a solar distillation. However, the use of these still has low productivity. There are several ways to increase the productivity of solar distillation systems, one of them is by adding thermal energy storage material such as aluminum oxide (Al2O3) nanoparticles. This study based on  experimental method by comparing a solar distillation systems with the addition of Al2O3 nanoparticles on the absorber plate coating to the coating without the addition of Al2O3. The test results showed that the addition of Al2O3 nanoparticles increased the productivity of solar distillation. The results show the addition of mass concentration of Al2O3 (nano particles): 10%; 15% and 20% ,  increased distillate  production by: 44.73%; 88.98% and 134.85% compared without the addition of nanoparticles to the absorber plate coating.

Abstract

The development of Renewable Energy (RE) has become one of the priorities that has been promoted by various governments around the world, as a step towards implementing green energy in accordance with the Paris Agreement. The sea as one of the largest parts of the territory in Indonesia must be managed for its energy because it has quite large energy potential. One of them is ocean currents. The Sunda Strait is a very strategic strait and has ocean currents that have the potential to develop energy to be used as a source of electrical energy. Therefore the development of a suitable turbine design is urgently needed in this strait area. In previous research the simulation and experimental work have confirmed that the Savonius rotor can be worked in the low speed marine current. This is will be relevant with Sunda Strait condition that have current 0.4 – 1 m/s. The experiment also shows that the rotor provided torque 0.36 Nm with 11.97 RPM therefore can generated 0.45 Watt

Abstract

Oil palm empty fruit bunches (OPEFB) as a by-product of the palm oil processing industry. This waste can cause problems for the environment and human health. Utilization of OPEFB waste as particle board material to reduce this waste. The composition of the particle board is based on volume fraction, namely 15% empty palm fruit fiber, 15% epoxy resin, 20% PVAc adessive, and 50% sawdust. The manufacturing process of samples was carried out using the single punch cold press method with compaction pressure of 10, 30, and 50 bar. The experimental results show that a compacting pressure of 10 bar can produce particle board performance according to SNI 03-2105-2006 with a characteristic density of 0.93 gram/cm3, thickness swelling of 2.52%, hardness of 24 N/mm2, flexural strength of 840.05 N/mm2, and impact strength 6.00 kJ/m2.

Abstract

Material engineering technology every year always makes new breakthroughs in creating high-quality materials and have an adequate contribution. Natural fiber reinforced composite material is one of the materials currently used as fillers in composite products. Composite with natural income also has a variety of advantages offered, namely low prices and abundant availability. This study discusses the fraction of fiber volume and fiber length on the tensile strength and impact of fiber reinforced silk fibers (Samia chynthia rucini). In this study the volume fractions of fiber used were 10%, 15% and 20% with a fiber length of 10 mm and 50 mm using an epoxy resin matrix. From the composite tensile test results prove the increase in tensile strength obtained increases the volume of silk fiber in the composite. 20% with a fiber length of 10 mm is 6.859 MPa, while the lowest tensile strength value in composites with a fiber volume fraction of 0% is 1.653 MPa. The impact test shows the strength of 10% fiber volume fraction composite with 10 mm fiber length that is 0.54535 J/mm2, while the lowest impact strength value is 0% fiber volume fraction composite that is 0.50686 J/mm2.

Abstract

This is The Stirling engine is one of the alternative power generators that can be implemented at this time. The power generated by the Stirling engine can be used as a generator of electrical energy or for automotive applications. This study aims to determine the optimum performance of the stirling engine in power and torque by providing variations in temperature. The test temperature was carried out by providing energy from LPG fuel with varying temperatures, namely 200˚C, 300˚C, 400˚C, 500˚C, 600˚C and 700˚C. The data taken is RPM, power and torque. From the test results, for 200˚C is 16 W, for 300˚C is 30.66 W, for 400˚C is 45.72 W, for 500˚C is 67.5 W, for 600˚C is 81.06 W, for 700˚C is 105.27 W. In this study, a variant of changing the weight of the flywheel was also carried out. The test results show that an increase in flywheel weight of 1 kg causes an increase in RPM of 22.7% and power of 22.7%.
