Abstract

This paper focuses on the calculation of sizing ducting based on cooling load requirements the main ducting of office building following regulation airspeed requirements using American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) and Computational Fluid Dynamics (CFD) simulations. The purpose of this research is to validate the airspeed and turbulence that occurs in the main ducting between manual calculations and CFD simulations. From the calculation, the cooling load requirement is 58.22 kW, for the cooling process an air flowrate of 7117 L/s is needed which is designed to pass through the main ducting in rectangular shape. The main ducting size uses 1200 mm x 500 mm at a speed of 12.7 m/s according to ASHRAE. Autodesk Inventor software is used for ducting modeling and Autodesk CFD is used for airflow simulation. CFD simulations are performed by applying boundary conditions and input parameters. The results showed that the velocity of the ducting design was suitable at 12.7 m/s with laminar flow. The ducting geometry must be designed aerodynamically to reduce the pressure drop which can cause the speed to increase so that it is outside the required limits. Thus, the CFD simulation results have verified the validity of manual calculations.

Abstract

The electricity is very important to support activities in office building .The equipment like AC ( Air conditioning ) needs more electricity to be operated. The is almost 60%  is use to support this system (AC). This percentage describe that air condition system is an equipment that needs more electricity in the office and its become inefficiency in using electricity. To take overcome for this problem we need to efficiency in using energy. One of the method that now used to efficient that energy is called “ energy conversation” This method is using to saving the energy There is one thing that must be done in this activity which is “ energy audit “. Audit energy is one of method calculate IKE (  Intension Consumption  Energy) at on the building.The first preliminary audit shown that more energy, which 60% is use to operated the air conditioning (AC) system and 30% to operate lighting system. IKE for the lighting system is still below from maximum standard  which is 15 watt/m²The opportunity of saving energy on audit energy in AC system is done by cleaning up consist of : cleaning up filter, propeller corner fin of the evaporator, and the grill of in door unit.

Abstract

Engine oil has an important role in the design and operation of all automotive engines. Used engine oil is a waste product produced in high quantity in the workshop garage which commonly found in most cities in Indonesia. The utilization of used engine oil has shown potential as retarder by reduce the setting time of mortar. In this study mortar was made by mixing cement,light aggregate, water, and engine oil both new and used as admixture ranged 0-1%. Mortar sample treatment is carried out at room temperature. The samples were tested for setting time and compressive strength after 3, 7 and 28 days curing. Scanning Electron Microscope characterization was carried out to to find out the morphological structure of resulting mortar. Results shown that the mortar with the addition of 0.75% used engine oil has the highest compressive test result of 9.31 MPa when the mortar reached 28 days compared to mortar without engine oil addition has a compressive test result of 7.546 MPa. SEM Images shown there are more ettringite presents in mortar with used engine oil addition.

Abstract

Pumps in modern human life have become a major need, and their use is very wide, therefore pump learning is indispensable for mechanical engineering students. For pump performance learning media, Pump Performance Test Equipment (PPTE) is needed. The test equipment requires a strong frame and meets the requirements to be able to withstand the load, not only the equipment load but also the water weight used as the working fluid on the performance test equipment which is very large. This study aims to design a frame that can withstand the entire load of the PPTE. The design is done by calculating the load experienced by the frame when the test equipment is operated. The design of this pump performance test framework uses the VDI 2221 method, which includes several stages: task clarification, design concepts, concept embodiment, and design details. The results obtained from the use of the VDI 2221 method are variation 1, with a frame of 1000mm length, 1200mm width, and 1140mm height. The frame specifications using 4x4 hollow steel size with a thickness of 2mm and 4x6 size with a thickness of 3mm, and using a wheel type with a lock that can withstand the load. maximum up to 600kg.

Abstract

Electro-deposition process to develop surface layer on the substrate material in Catalytic converter (CATCO) become interesting area due to that process was purposed to improve the physical properties of substrate material. Currently, precious metals such as Platinum (Pt), Palladium (Pd), and Rodium (Rd) were used due to excellent oxidation resistant but it limited and easily oxidized. Therefore, Nickel Oxide (NiO) catalyst used as electro-deposition material. NiO electro-deposition technique that called by EL was conducted by using NiO as cathode and FeCrAl as substrate and -Al2O3 as washcoat material. This technique was performed by  variation times of 15, 30, 45, 60 and 75 minutes, current density of 8 A/dm2. The results shows that Coating layer of NiO and  -Al2O3 has been developed on surface of FeCrAl substrate. The coating layer was increase the surface roughness which showed by surface morphology data that coated FeCrAl substrate has uneven surface and some particles has been embedded on that surface. The composition of raw material was consists of Fe for 74.13wt%,  Cr of 20.25 wt% and Al of 5.62 wt%. Meanwhile, for composition of EL samples was 52.56- 63.54wt% for Fe element, Al for 3.56-11.89 wt%, Cr for 14.97-18.56 wt%, O for 2.47-11.78 wt%, C for 8.33-11.85 wt%, Na for 0.11-0.48 wt%  and Ni for 0.17- 1.58 wt%.  Higher elements of the EL samples potential to improve the thermal stability at high temperature due to CATCO operate at high temperature of 600-8500C and in extreme condition.
