Abstract

Indonesia is one of the largest palm oil-producing countries globally, with a production value of 40 million tons by 2020. Biodiesel is one of the alternative energy sources that can be processed from palm oil. Diesel engines can directly use biodiesel as a fuel. Biodiesel has distinct characteristics from diesel; thus, it will affect performance and other things on the engine. In this research, diesel engine performance tests were carried out, including specific fuel consumption (SFC), cylinder head temperature, cylinder block, and exhaust pipe, with a test time of 300 hours. This research aims to determine the effect of the cylinder head, cylinder block, and exhaust pipe temperatures on SFC using two different fuels, i.e., B100 and B20. Based on the test results, the average cylinder head, cylinder block, and exhaust pipe temperatures on the B100 engine are 136 oC, 130 oC, and 257 oC. As for the B20 engine's cylinder head, block, and exhaust pipe temperatures are 139 oC, 132 oC, and 264 oC. Engine with B100 fuel obtained SFC of 0.317 kg/kW.hour and engine with B20 fuel obtained SFC of 0.276 kg/kW.hour. In general, the combustion temperature in the cylinder head affects the increase in SFC in both engines with different fuels; the higher the combustion temperature in the cylinder head, the higher the SFC is. Engines with B100 fuel have a higher SFC value than B20 fuel, which is influenced by the higher viscosity and density values; thus, the droplets from the fuel atomization process become larger when compared to fuels with lower viscosity and density values. The graph analysis shows that the cylinder block temperature graph on the B100 and B20 fueled engines decreases between temperatures of 133-134 oC, then inflates with the increase in specific fuel consumption. The higher temperature compared to the B100 fuel engine makes the fuel undergo complete combustion when injected into the combustion chamber due to atomization or very fine droplets burning completely. The cylinder block temperature chart on the B100 and B20 fueled engines has a very significant trend difference. B100 engines tend to experience a decreasing trend in temperature along with an increase in SFC, while B20 engines tend to experience an increasing temperature trend along with an increase in SFC.

Abstract

One alternative energy that can e developed in the future is water. The water can produce future fuels, namely hydrogen and oxy-hydrogen, through the electrolysis of water. Electrolysis of water is one way to produce hydrogen into electrical and thermal energy conversion of hydrogen and oxygen. This study used a dry cell type HHO generator to produce Oxy-hydrogen. Oxy-hydrogen consists of two hydrogens and one oxygen or Oxy-hydrogen (HHO). Carried out to determine the optimal performance of the mass fraction of the catalyst on the productivity of Oxy-hydrogen by mixing 2500 ml of air and NaHCO3 as a catalyst. The observed mass catalyst fractions were 0.69, 1.38, 1.77, 2.15, 5 7.5, 10, and 15%. The results showed that the best Oxy-hydrogen production performance using a catalyst was 10% catalyst mass fraction with a production rate of 0.02250 l/s with an efficiency of 36.98%.

Abstract

Struvite was a white crystal known as Magnesium Ammonium Phosphate Hexahydrate (MgNH4PO4.6H2O). In industry, struvite was found in the pipes crust which the hot fluid through passes. Struvite is often used as fertilizer because it contains phosphate content. The one of benefits of struvite crystals is slow release fertilizer, so it can be more durable, which is good for the growth of the plants. The Precipitation technology is currently one of the most widely applied technologies in struvite formation. The process of forming struvite is carried out by using a vertical reactor. The process started by mixing the equimolar solutions of MgCl2, NH4OH, and H3PO4 with a concentration ratio of 1: 1: 1 and 1: 1: 2. Theprocess was carried out with the condition at the 30°C while the air inlet rate was 1.25 liters/min. The pH of the solution is pH 9 and controlled using NaOH solution. The process was carried out in the steady state condition. Then the solution was filtered and solid was dried at room temperature for 48 hours. From this study, the concentration ratio of 1:1:2 was obtained the best of struvite compared to the others ratio. The solid was analyzed by using the SEM-EDX instrument. The morphology of struvite was formed an irregular pyramid like crystal or commonly referred to as an authorhombic shape.

Abstract

The objective of this study is to investigate the wear mechanism of UHMWPE acetabular liner. There were three samples of acetabular liner with variations without crosslink, with crosslink doses of 50 kGy and 100 kGy which were subjected to a wear testing process. The wear test was carried out using a Tribometer wear testing machine with a total of 30,000 cycles and a load of 800N. Microstructure analysis was performed using scanning electron microscopy (SEM). The results show that the surface of the UHMWPE acetabular liner with the crosslink treatment is smoother than the untreated one. This shows that UHMWPE with crosslink treatment has a lower wear rate, where the greater the crosslink dose the lower the wear rate. The wear mechanism that occurs in this study is the third body abrasion which leads to adhesive wear.

Abstract

Reverse Engineering (RE) can be interpreted as procedures and processes in dismantling an object to find out the materials, working methods, or technology used so that the object can function properly. Design activities using the reverse engineering concept make it easier for students to understand product specifications, product advantages and disadvantages, product production processes and production cost estimates before designing new products. The laboratory is one place that can be used to carry out the reverse engineering process. The bulkhead reactor is an alternative to the stirred tank reactor with the aim that the resulting product is maximized both in terms of quantity and morphology or shape of the material. The benefit of disassembling this product is as a first step in understanding the concept of reverse engineering in the task of designing machines or tools. From the results of the study, it was found that the formation of struvite occurred at pH 9 using an air flow rate of 1 l/minute.

Abstract

Combustion is a very complex matter. Therefore, we need to know the phenomenon that occur in combustion apart from the temperature distribution. This research uses quasi-research. The background in using quasi-experimental is because it has advantages in data collection. Moreover, the phenomena that occur in more detailed research by means of a numerical approach could also be observed. This research was conducted with an approach (simulation) of diffusion combustion using methane (CH4) fuel and air containing 29% oxygen (O2), 71% nitrogen (N2) and the addition of swirl in the air ducts. k-ɛ turbulence modeling was aaplied in this somulation. This variation of the fuel velocities are 3 m/s, 5 m/s, 7 m/s, where the air velocity was varied for 3 m/s, 5 m/s, 7m/s. In this simulation, room pressure of 1 atm was applied for the surrounding. The results showed that, the greater the angle of inclination of the swirl burner, the shorter the flame. And on the variation of fuel velocity, we get the result that the higher fuel velocity, increase fire height; however, the temperature of the fire height will decrease.
