Abstract

Coconut oil combustion characteristic is observed experimentally by evaporating oil in the boiler then mix it with air before being burned at various equivalence ratios in the Hele-shaw cell. The result shows that, coconut oil tends to break into glycerol and fatty acid due to hydrolysis reaction producing the flame propagation, where the fatty acid flame propagates first then glycerol flame. Micro-explosion occurs when moisture from fatty acid combustion is absorbed by glycerol and higher heating due to higher flame speed produces more micro-explosion.

Abstract

Coconut oil premixed combustion behavior has been studied experimentally on perforated burner with equivalence ratio (φ) varied from very lean until very rich. The results showed that burning of glycerol needs large number of air so that the laminar burning velocity (SL) is the highest at very lean mixture and the flame is in the form of individual Bunsen flame on each of the perforated plate hole. As φ is increased the  SL decreases and the secondary Bunsen flame with open tip occurs from φ =0.54 at the downstream of perforated flame. The perforated flame disappears at φ = 0.66 while the secondary Bunsen flame still exist with SL increases following that of hexadecane flame trend and then extinct when the equivalence ratio reaches one or more. Surrounding ambient air intervention makes SL decreases, shifts lower flammability limit into richer mixture, and performs triple and cellular flames. The glycerol diffusion flame radiation burned fatty acids that perform cellular islands on perforated hole.  Without glycerol, laminar flame velocity becomes higher and more stable as perforated flame at higher φ. At rich mixture the Bunsen flame becomes unstable and performs petal cellular around the cone flame front.

Abstract

Characteristics of composite materials that are light, strong, heat resistant, and high hardness are needed in their application. This study aims to obtain a hard material and good heat conductivity, with the innovation of making aluminum matrix composites (AMC) from aluminum powder as a matrix, combined with silicon-carbon whisker (SiCw) and alumina particles (Al2O3p), and adding Magnesium through the powder process metallurgy. The method of making composites was carried out by means of powder metallurgy. The research variables composition I, II, and II with Al/(SiCw+Al2O3/Mg), were given temperature treatment: 500, 550, and 600oC. The test results show that there is an increase in the mechanical properties of the composites both from variations in composition and also from variations in treatment temperature because the bond resulting from the addition of Al2O3 reinforcement has hard and fine grain properties. The physical and mechanical properties of the test results are in the form of the highest density at composition I, 600oC (2,699 gr/cm3) while the hardness at composition III is 600oC (42,438 HV) and heat conductivity at composition III, 600oC (185,183 Watt/m.oC). Scanning with SEM showed that the pore size decreased from the treatment temperature of 500oC to 600oC due to phase changes and a stronger bond between the matrix and the reinforcement. So that the influence of composition and temperature will affect the thermal conductivity, hardness, and density of the composites.

Abstract

PT. TSW (Tuban Steel Work) is a company engaged in manufacturing fabricated (make to order) with the commitment and the goal of providing effective services, convenient and timely delivery. But in fact, the company's commitment to the purpose can not be achieved that delays the project completion time is not in accordance with the order due date. Based on the observations made in the study, this is due to some events that can not add value or called by the waste (non-value added). This study aims to identify waste, analysis of contributing factors and recommendations for improvement as the system improvement efforts in creating customer value. By using the concept of lean manufacturing this study begins by describing the current state map and weighting of the waste system, waste weights were analyzed by matrix VALSAT used to identify waste in the system, to analyze the causes of waste by fishbone diagram to illustrate the root cause of waste and failures mode system analysis using failure mode and effect analysis (FMEA) to determine the value of risk priority number (RPN) of the potential causes and potential effects of waste that occurs. The results showed that the waste that occurs is that there are waiting on purchasing activities (supplier), marking-up cutting and fit-up welding. From the discussion, the company recommended improving information systems internal-external (supplier) as well as improvements in the fabrication process activities.Key words: lean manufacturing, VSM, VALSAT, RCA, fishbone diagram, FMEA, SCRM, VMI.

Abstract

The groved surfaces are widely researched to reduce pressure drop and control a flow on the surface. In applicative fluids flow is turbulen. So, the grove addition capable of affecting the boundary layer condition near the wall pipes. This will greatly determine the pressure drop and the flow patterns that occur during the fluids flow. The purpose of this researched is to analyse the impact of the number of grooves in pipes against the pressure drop and the occurred flow patterns. In this researched, we used 3 pipes, which total of grooves were 4,8,16 and the pipes without grooves that used as comparator. The observed flow was two phases flow ( air-water). The researched pipes used acrylic pipes with diameter of 1 inch and length of 100 cm with the groove used was type of scalloped groove. Pressure drop occurs in all of the grooves ; 4,8, and 16. The highest pressure drop decrease occurred in groove 16. When there was drop in pressure drop in every single of groove, in low air discharge, bubbly that firmed was more tightly without making slug flow. When the debit was getting bigger, the bubbly was reduced and followed by the emergence of slug flow. The changes in water debit in the decrising of pressure drop in every single of drop, shows the dencity between the bubbly and slug flow that firmed

Abstract

Stereo vision is one of the interesting research topics in the computer vision field. Two cameras are used to generate a disparity map, resulting in the depth estimation. Camera calibration is the most important step in stereo vision. The calibration step is used to generate an intrinsic parameter of each camera to get a better disparity map. In general, the calibration process is done manually by using a chessboard pattern, but this process is an exhausting task. Self-calibration is an important ability required to overcome this problem. Self-calibration required a robust and good matching algorithm to find the key feature between images as reference. The purpose of this paper is to analyze the performance of three matching algorithms for the autocalibration process. The matching algorithms used in this research are SIFT, SURF, and ORB. The result shows that SIFT performs better than other methods.

Abstract

The dairy cattle productivity is very depending on the quality of their facilities and their environment condition. A lot of researches have been done in this area, but it is not developing the knowledge of animal dimensions and behaviours correlated with their facilities design. Complexities of dynamics zoometry is very depending on cow behaviours that it forced to use neural network (NN) approaching. Hence, the purposes of the paper  is to create the concept of static and dynamic zoometry approach to guide the ergonomics facilities design and the modern of dairy cattle house based on zoometry data by using artificial neural network. The research is started with study literature of anthropometry, CAD design, dairy cattle, facility design and neural network. The next step is collecting the data of cow dimensions for static zoometry (17 variables) and cow behaviours for developing the concept of dynamics zoometry (5 variables). The static data is used as input factor and dynamic data as desire of Back Propagation NN model. The result of BPNN training is used to design the dairy cattle facilities, e.g. 3D CAD house with minimal length = 357.67 cm, minimal width = 132.03 cm (per tail) and minimal height = 205.28 cm. Finally, the paper is successfully developed the concept of zoometry approach and BPNN model as pioneer of implementing comfort knowledge.

Abstract

This study aimed to determine the effect of adding the sluice gate and the optimal width of the sluice gate on the waterwheel performance. Tests have been carried out experimentally on a laboratory scale. In the test, this study used an open channel waterwheel with variations in the flow gap width gate width of 25mm, 35mm, and 40mm. Each variation of the flow gap width will be tested at a flow rate of 12 liters/second. Parameters such as mill power, turbine torque, and efficiency will be determined based on the measurement results of the rotational speed of the waterwheel wheel, water level, and braking load. The results showed that the width of the sluice gate flow gap affects the performance of the waterwheel. The highest performance was obtained at a flow gap of 25mm followed by a flow gap width of 35mm, and the lowest performance was obtained at a variation of the slit width of 40mm. The maximum performance of the waterwheel is obtained at variations in the width of the flow gap of 25mm at 50 rpm rotation conditions with a discharge of 12 liters/second where liters were generated 15.06 watts and the efficiency 29.82%.
