Abstract

The desiccant wheel performance of desiccant cooling system components is very important whose function is to regulate air humidity levels as well as to the capability, size and cost of the entire system. Mathematical models for predicting the performance of desiccant wheels in the development of mathematical models is one of the effective methods for analyzing the performance of wheel this moisture-reducing. This mathematical model can also be used in guiding system operation, delivering experimental results and automation in designing this cooling system. The purpose of this paper is to provide an overview of efforts to mathematically model the process of heat transfer and mass transfer that occurs in the moisture-reducing wheel. The desiccant wheel model built here is a gas and solid system including basic principles, heat and mass transfer mechanism and model building. The model is based on ideal assumptions, equations, additional conditions and the method of solution and also the main results. The gas-solid model is a more precise and more complex model than the other models. From these results the evolutionary process of the mathematical model is obtained and the aspects of calculation of pressure loss, air leakage, and optimal rotation speed of the drying wheel / dehumification.

Requirements of fuel oil increases along with the increasing their consumption in many sectors such as transportation, industrial and others. This issue has attracted great reseacher’s attention to find the alternative solution as a substitute for fossil fuel energy. Oxygen Hydrogen Hydrogen gas (HHO) can be used as one of this solution. HHO gas can be produced using wet cell HHO generator type. The objective of this research was to construct a simple wet cell HHO generator system and determine the performance of this generator. We use galvanized steel pelate as electrode with thickness 1,2 mm, NaOH catalyst in the electrolyte solution. The results showed that the HHO gas maximum productivity of the cell was 0,0022 L/h, the highest efficiency was 11% with a power consumption of 69.3 Watts.

Abstract

The objective of this research is to determine the acoustic properties (sound absorption coefficient) in a various length of betelnut fibers. Betel nut fibers were obtain from local plantation in Padang as agro waste material and potentially used as sound absorber. In this study, we used betel nut fibers as a filler of composites and epoxy resin as a matrix using the ratio of volume fraction of 40% : 60%. We used three variations of fibers length such as 1 cm, 2 cm and 3 cm. The sound absorption coefficient of composites was studied using impedance tube method with 1000 Hz, 1500 Hz, 2000 Hz, and 2500 Hz frequency. The results showed that composite using 3 cm fibers length of betelnut husk would give the optimum sound absorption coefficient at 1500 Hz frequency, but composites with 1 cm fibers length showed a great performance as sound absorbing materials at various sound frequencies that have been tested. From this research shown that betelnut fiber composite give the optimum sound absorption coefficient at various fibres length and can be used as sound absorption materials, based on ISO standard 11654:1997.

Abstract

The potential of wind energy in Indonesia is sufficient for the development of renewable energy based on wind turbine, because the average wind speed ranges from 3-12 m / s. The wind that blows is dominated by West, Southwest, and Northwest winds with speeds sometimes reaching 2.5 m / s to 20 m / s. The designed wind turbine is a Taper type blade where the comparison of the tip chord to the base is 1.3: 1, with a blade length of 1 m. Where the blades are designed to be able to spin in high-speed winds and to maximize the efficiency that can be obtained. The design result that the highest peak is 59% at TSR 7 and the blades start to spin in winds of 8.7 m / s and at winds of 12 m / s the power produced reaches 3255 watts.

Abstract

This research aims to create an innovation in the design of Robot Manipulator with joint configuration in the form of two prismatic movements and two revolute movements (PPRR), serially. The Robot Manipulator design is validated by performing kinematics simulation and analysis of a trajectory. To simulate the movement of this Robot Manipulator, the end-effector Robot Manipulator is equipped with stationery in the form of a marker to follow the trajectory of the block letters. Robot Manipulator consists of four links. Link-1 moves prismatically on a horizontal linear sliding rail system (LSRS) with a rail length of 450 mm. The center point of Link-1 can move from a position of 75 mm to 375 mm in the X-axis direction. The Y-axis parallel links with a length of 80 mm move prismatically on a vertical linear rail system (LSRS) with a rail length of 60 mm. The conditioned link-2 can move from 140 mm to 180 mm in the direction of the Z-axis. Link-3 revolves in the X-Y plane with a range of 0o to 180o. Link-4 revolves in the X-Y plane with a range of 0o to 180o. From the simulation and kinematics analysis of Robot Manipulator with trajectory in the form of ITP block letters it can be concluded that the Robot Manipulator is indicated to be able to follow the trajectory well.

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

The manufacture of particle boards without synthetic adhesives is influenced by the composition of the material, temperature, time, pressure, particle size and method of manufacture. The pressure of one important parameter and its variations often produce different properties. Pine skin is a waste that is not valuable and just wasted. Making particle boards from palm oil empty bunches and pine bark waste is an interesting and new thing. Pinus merkusii leather powder is used as an added ingredient, its composition is 70% tkks and 30% pine merkusii powder with 5-6% moisture content, dry based. The fiber lengths are 0.1-2.0 cm and pressures are 2, 4, 6, 8 and 10 kg.cm-2, temperature 150, 160, 170, 180 and 190ºC. The standard for particle board reference and bending test is SNI 03-2105-2006 and ASTM D1037. The result show of working pressure and heating temperature affect the density, moisture content and MOR. Increasing pressure and temperature tend to increase the MOR value and increase in temperature above 190oC, the MOR value decreases.

Abstract

The purpose of this work is to analyze the kinematic of a manipulator that was designed to has four revolute movements (R1, R2, R3 and R4) and is equipped with a gripper that has one revolute movement (R) and one prismatic movement (P). The analysis was conducted by varying R1, R2, R3 and R4 of manipulator and R and P of gripper. Kinematic analysis was carried out using the Forward Kinematics method based on DH-Parameters of manipulator and gripper. Manipulator was designed to be consist of 120 mm of Link-1, 200 mm of Link-2, 250 mm of Link-3 and 250 mm of Link-4. Revolute movements range of manipulator was designed for variation of R1, R2, R3 and R4, and with movements range of gripper for variation of R and P. From this work can be concluded that manipulator has 228.5 mm of minimum range radius of end-effector and 547.0 mm of maximum range radius of end-effector.
