Abstract

Many applications of thermoacoustic engines in engineering. With its pressure of it, the energy can be harvested and can be converted to many other needs of energies like electrical energy. Energy in thermal form is converted to become acoustic energy and subsequently used to activate a bidirectional turbine. The resonator is very influential toward the power of the thermoacoustic engines. Simulation study with Delta EC fit to make predictions acoustic power as representative performance in thermoacoustic engine with close-open type and standing wave of oscillation. In this study, the material of the resonator is made from a stainless-steel duct with a diameter size of 50.8 mm with three variations of the length. The Standing-Wave Thermoacoustic Engine (SWTE) generates acoustic energy from a temperature gradient of 315 – 993 K. In this simulation, Acoustic Power decreased when the resonator length was extended. The shortest resonator had an acoustic power of 50.4 W, and the longest resonator had an acoustic power of 35.7 W.

Abstract

The cutter planer is one of the main components of a bamboo planer which functions to flatten the surface of the bamboo blades. The cutter planer has a problem, namely the maximum stress is not known due to the complexity of the components which is difficult to analyze using the mechanical equation calculation method, so that to overcome this problem a numerical method is used, namely the finite element method. In this study, an analysis was carried out on a cutter planer by comparing the process of cutting bamboo slats with two directions of rotation clockwise (CW) and counterclockwise (CCW). The material used in the cutter planer is HSS and bamboo material with petung bamboo. The results of this study show that the highest maximum stress distribution for the cutter occurs in CCW and the lowest maximum stress distribution for the cutter occurs in CW.

Abstract

A study of the surface of the fabrication process using the fused deposition modeling (FDM) technique is needed to determine the suitability of the process parameters with the use of the product to be made. Products that have special characteristics that take advantage of the surface properties of fabricated using FDM are often encountered in technical applications involving fluids. This research is a preliminary study of the Water Contat Angle (WCA) study on polymer filaments made of PLA. In this study, the effect of printing speed on the width of polymer deposition and the gap distance between one deposit and another polymer deposit on the sample surface was observed and analyzed using image processing techniques. The printing speed is made to vary from 30 mm/s, 60 mm/s, and 90 mm/s. The relationship between printing speed and polymer deposition width produces a linear equation y = 0.0008 x + 0.28 and the gap width between filament deposition on the sample surface shows a linear equation relationship y = -0.0002 x + 0.0833

Abstract

Styrofoam (Extruded Polystyrene) waste can be used as a soundproofing material. This study aims to determine the effect of the particle composition of Styrofoam and epoxy resin on the performance of soundproofing composites. The composition between Styrofoam particles and epoxy resin is 20:20; 20:30; and 20:50 grams. Sound absorption test using PVC impedance tube 100 cm long, 15 cm diameter, and 5 mm thick. The variation in the placement distance of the composite from the sound source is 25; 50; and 75 cm and was measured using the sound level meter application. This type of test sound uses a single tone in the frequency range of 0-600 Hz which is recorded per 5 seconds. Composite performance analysis is reviewed based on media density, composite morphological characteristics of Image-J software, and sound absorption coefficient values. The results showed that the greater the composition had increased the density value of composite particles accompanied by a decrease in pore area in the composite media which resulted in a sound absorption coefficient of 15.61 dB at a composition of 20:50 with a distance of 25 cm from the sound source.
