Abstract

Panel surya dapat mengubah energi matahari menjadi listrik, Penggunaan panel surya masih memiliki kendala, salah satunya adalah efisiensi daya keluaran yang masih rendah. Salah satu cara untuk meningkatkan efisiensi daya keluaran panel surya adalah dengan mengatur temperatur panel surya. Temperatur panel surya yang terlalu tinggi akan mengurangi efisiensi panel surya, sehingga diperlukan sistem pendinginan untuk menjaga temperatur panel surya tetap pada temperatur yang optimal. Variasi laju aliran pada tubular cooler serta pelapisan kaca film digunakan pada penelitian ini. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh tubular cooler dan kaca film pada panel surya terhadap daya keluaran, efisiensi maupun temperatur yang dihasilkan. Metode penelitian yang digunakan adalah metode eksperimental dengan menggunakan sistem pendingin tubular cooler dan kaca film pada panel. Pengambilan data dilakukan selama 6 hari dikondisi luar lapangan. Tingkat kegelapan kaca film divariasikan dan membaginya menjadi dua kelompok penelitian. Pada penelitian pertama digunakan kaca film 0% dan variasi laju aliran 1,2 L/menit, 1,6 L/menit dan 2 L/menit. Pada kelompok penelitian kedua menggunakan kaca film 20% dan variasi laju aliran 1,2 L/menit, 1,6 L/menit dan 2 L/menit. Hasil penelitian pada kelompok pertama menunjukkan panel surya mengalami penurunan temperatur terbesar hingga 11,69%. Penuunan temperatur yang terjadi, menghasilkan peningkatan daya keluaran hingga mencapai 31,88% dibanding panel tanpa pendingin. Pada penelitian kelompok kedua, penggunaan kaca film 20% sangat efektif dalam menurunkan temperatur panel hingga 15,84%, tetapi mengalami penurunan daya keluaran. Penurunan ini disebabkan karena adanya pengurangan intensitas matahari yang diterima oleh panel.

Abstract

Manufacturing technology has experienced significant progress with various innovations, including 3D printing. In this study, an innovation was made using a filament made of PLA 60% and titanium 40%. Bending tests are carried out to determine the combination of 3D printing parameters that can produce the most optimal bending strength. This study uses the Taguchi method orthogonal matrix L4(23). The data is processed using Analysis of Variance (ANOVA). The parameters that produce optimal bending strength values are a nozzle temperature of 230 ⁰C, a print speed of 20 mm/s, and a layer height of 0.3 mm, with the highest bending strength value of 7.13 MPa and the lowest of 2.16 MPa. The factors that contributed significantly to the bending strength results were nozzle temperature of 52.84 %, print speed of 15.91 %, and layer height of 1.80 %.

Abstract

Heat energy is generally only used by humans for heating an object and then heat wastefully into the environment without being converted into other energy. This study aims to find out how to utilize waste heat from 6U type refrigerator condensers by using thermoelectric generator modules. This study uses an experimental method that is used to compare the performance of a thermoelectric generator to convert waste heat from a condenser to a variation of 120cm2, 96cm2, and 72cm2 heatsink area. In the study taken every 5 minutes for 2 hours this results in a declining value. The variation of the 120cm2 heatsink area produces a temperature difference of 12.4oC - 9.4oC, the output power is 0.00119 Watts - 0.00072 Watts, and produces an efficiency of 0.014% - 0.011%. In testing the variation of 96cm2 heatsink area, it produces a temperature difference of 8.1oC - 5.3oC, the output power is 0,00055 Watt - 0,00025 Watt, and produces an efficiency of 0,010% - 0,007%. In testing the variation of the 72cm2 heatsink area it produces a temperature difference of 6.9oC - 4.5oC, the output power is 0,00042 Watts - 0,00019 Watts, and produces an efficiency of 0.009% - 0.006%. Of the three variations of the heatsink area that have been tested, the variation of the 120cm2 heatsink area produces the best results compared to other heatsink area variations.

Abstract

Indonesia still relies on the use of energy from non-renewable sources, especially oil and coal. However, the supply of energy from fossil sources is decreasing. The energy conversion process in solar panels causes an increase in temperature, especially in conditions of intense sunlight and hot weather. High temperatures can accelerate the degradation of materials in solar panels. Therefore, a cooling system needs to be developed to lower the temperature of the solar panels to produce electricity efficiently. This study aims to examine how the efficiency of solar panels can be affected by cooling fluids. The experimental method is used by setting the solar panels at an angle of 30°. Data is collected during sunny weather conditions with sunlight levels above 2000 lux. The solar panel used is a 20 WP monocrystalline type. The recorded data includes several parameters, namely current, voltage, light intensity, and solar panel temperature. The results indicated that solar panels with cooling had a lower surface temperature compared to solar panels without cooling. In addition, cooled solar panels have a higher efficiency than uncooled solar panels. Using a cooler with a certain discharge on the surface of a solar panel can increase efficiency significantly.

Abstract

Biodiesel predicted to replace diesel fuel in the future that comes from the transesterification process of plant oils, animal fats, or used oils. One of the potential raw materials is nyamplung seeds because they are scattered in Indonesia, easy to cultivate, and bear fruit throughout the year [1]. The purpose of this study was to determine the effect of mixing pure diesel fuel and nyamplung biodiesel with the fuel composition B0, B20, B30, and B100 on the spray tip characteristics penetration, spray angle, and sauter mean diameter.This study focussed on simulation. The simulation method is carried out to predict the distribution and mean diameter of droplet using commercial fluent software. Fuel spray is carried out in free air with an injection pressure of 15 MPa, fuel temperature 28.2 ℃ and free air temperature 30.1 ℃. The spray process was taken at 6.25 ms and then the fuel spray characteristics were measured using the ImageJ application.The results of testing the fuel spray characteristics indicate that the amount of biodiesel content in the fuel is 20-100%. It can increase the length of spray tip penetration about 0.7-4.9%, a decrease in spray angle of 9.2-32.1% and the sauter mean diameter value increased by 20.1-84.6%. It caused by increasing the amount of biodiesel content in the fuel which results in an increase in the value of density, viscosity and surface tension of the fuel.

Abstract

The KMHE competition which focuses on optimizing energy in developing cars is held as a form of contribution to overcoming the problem of dwindling energy sources. To get a cell phone with low energy consumption, one alternative is to design a cell phone as often as possible. This research examines the effectiveness of topology optimization methods in making lightweight component designs while maintaining the ability to accept loads when applied. The components that are being optimized are the support brackets on the main shaft steering of Car TITEN EV-2 which are produced using additive manufacturing with PLA+ materials. The load borne by the design is the load when the car is braking and turning. Two Topology Optimization experimental methods were carried out based on the loading arrangement. The first method is carried out by combining two topological optimization results based on loading to produce the final design. The second method is carried out by applying the two loadings simultaneously to the TO process. As a result, the second TO method showed very good results compared to the first method and was redesigned to produce a new design that was ready for use. The results of the new design have a mass of 34.25% lower than the original design. The FEA simulation results also show the results of increasing design strength after topology optimization. The maximum von-mises voltage drop of the new design in the case of braking, turning and combined loading (braking and turning) respectively is 12.56 MPa, 11.64 MPa and 17.99 MPa compared to the original design which is 30.16 MPa, 26.19 MPa and 51.9 MPa.

Abstract

3D printing of fused deposition modeling (FDM) technique is one of the most widely used nowadays. One disadvantage of this method is that the printed product has low strength to the fact that the product is developed layer by layer. This research aims to combine PLA, PP, and ABS and determine which results in the highest flexural strength. A Cartesian 3D printer printed specimens according to the ASTM D790 standard. Then, specimens were tested using a universal testing machine. An optic microscope was used to observe the fracture area. The results showed that the combination of PLA-ABS increased flexural strength up to 33.12 MPa. While PLA-PP, PLA-PP-ABS and PP-ABS resulted in a flexural strength of less than half PLA-ABS one, they were 14.90, 14.59 and 12.10 MPa, respectively. All alloy combinations except PLA-ABS were delaminated during the bending test. Delamination causes a decrease in the flexural strength of a specimen.
