Abstract

Micro friction stir welding (μFSW) adalah pengelasan friction stir welding untuk ketebalan maksimal 1 mm. Tujuan penelitian adalah mengetahui pengaruh feed rate dan sudut kemiringan pin tool pada μFSW aluminium 1100. Pengelasan dilakukan dengan variasi sudut kemiringan tool 0°,1° dan 2°, dengan variasi feed rate 66, 85, dan 120 mm/menit serta kecepatan putaran pin tool 2280 rpm. Jenis sambungan yang digunakan adalah sambungan butt. Pengujian yang dilakukan adalah pengujian struktur mikro dan cacat makro dengan mikroskop optik, uji kekerasan, dan uji kekuatan tarik. Hasil pengamatan makro terdapat cacat lasan pada variasi feed rate yaitu cacat incomplete fussion. Hasil pengamatan struktur mikro menunjukkan bahwa grain size pada stir zone (SZ) semua variasi tampak lebih kecil dibandingkan pada BM dan HAZ menyebabkan nilai kekerasan pada HAZ dan SZ lebih tinggi dari pada BM. Semakin bertambah kecepatan feed rate dan sudut kemiringan tool maka kekerasan daerah SZ dan kekuatan tarik semakin meningkat. Heat input yang tinggi mengakibatkan pendinginan lebih lambat sehingga butiran lebih besar dan menyebabkan penurunan nilai kekerasan. Kekerasan tertinggi pada feed rate 120 mm/menit sebesar 73,7 VHN dan kemiringan tool 2o sebesar 64,7 VHN. Kekuatan tertinggi pada feed rate 120 mm/menit sebesar 84,84 MPa dan pada sudut kemiringan 2o sebesar 111,36 MPa. Micro friction stir welding (µFSW) is friction stir welding for a maximum thickness of 1 mm. The aim of the research was to determine the effect of the feed rate and the tilt angle of the pin tool on 1100 µFSW aluminum. Welding was carried out with variations in the angle of the tool tilt of 0°, 1° and 2°, with variations in the feed rate of 66, 85, and 120 mm/min and the pin rotation speed. tools 2280rpm. The type of connection used is the butt joint. The tests carried out were testing the microstructure and macro defects with an optical microscope, hardness test, and tensile strength test. The results of the macro test showed that there were defects in the feed rate variations, namely incomplete fusion defects. The results of microstructure testing showed that the grain size of the stir zone (SZ) of all variations was smaller than that of BM and HAZ causing the hardness values of HAZ and SZ to be higher than that of BM. As the speed of the feed rate and the angle of inclination of the tool increase, the hardness of the SZ region and the tensile strength increase. High heat input results in slower cooling resulting in larger grains and causes a decrease in hardness values. The highest hardness at a feed rate of 120 mm/minute is 73.7 VHN and the slope of the tool 2o is 64.7 VHN. The highest strength at a feed rate of 120 mm/min is 84.84 MPa and at an angle of 2o is 111.36 MPa.

Abstract

Biodiesel has attracted attention as an alternative fuel in efforts to reduce emissions and dependence on fossil fuels. Among various potential sources for biodiesel production, jatropha and corn oil have stood out due to their availability and high yield potential. However, each has unique characteristics that affect their performance as fuels. Jatropha oil has relatively high viscosity, while corn oil is generally used as a food ingredient. This study aimed to explore the potential of combining jatropha and corn biodiesel in different proportions and its impact on fuel characteristics and diesel engine spray injection. Both types of oil were processed into biodiesel through esterification and transesterification processes. Subsequently, biodiesel mixtures were created in ratios of 1:4 and 4:1. Each mixture was then varied with diesel to produce B5, B10, B15, B20, B25, B30, B35, and B40. Each sample was tested for its physical properties such as density and viscosity, and injection spray angle. The results of this study indicated that the density and viscosity values of the 1:4 jatropha-corn biodiesel mixture were lower than those of the 4:1 jatropha-corn biodiesel mixture. There was a significant relationship between viscosity and density with the injection angle. The higher the density and viscosity, the narrower the injection angle.

Abstract

One of the most popular materials used in industry is aluminum and its alloys. The aluminum manufacturing process is likely to undergo a welding process. Aluminum can be welded by gas or arc welding, but arc welding is more satisfactory. The welding process on aluminum alloys has the potential to present a situation similar to Age hardening. This research was conducted to dig deeper into the impact of welding on the second phase strengthening mechanism in several series of aluminum alloys using impact test equipment with the addition of a modified digital instrumentation device. Modifications were made to the GOTECH impact test equipment model Charpy impact test 0027 by changing the pendulum and adding a plate to the holder to conform to the ASTM E23-02a standard and adding digital instrumentation tools, including load cells, amplifiers, data acquisition, and power supply. The specimens used were aluminum 5052 and 6061 with variations of base metal and TIG welded V 60°. The results of the modified impact test equipment can display a graph of the impact energy absorption of each specimen. Comparison between the manual calculation of absorbed impact energy and digital calculation of 5052 base metal aluminum specimens has an average deviation of 11,716 J, 5052 welded specimens have an average deviation of 1.341 J, 6061 base metal specimens have an average deviation of 0.729 J, and 6061 welded specimens has a mean of 0.845 J.

Abstract

Termites are commonly seen as a nuisance due to their capacity to cause harm to wooden objects. The occurrence of termite infestations on furniture has led to a rise in financial damages attributed to such attacks. Hence, it is of utmost need to seek alternative raw materials that exhibit resistance to termite-induced deterioration, thereby fulfilling the requirement for substituting particle board. The present study has successfully demonstrated the fabrication of particle board by including bintaro fruit seed filler and urea formaldehyde matrix. The primary objective of this research endeavor was to explore an alternate approach to standard particle board production, specifically focusing on the development of anti-termite qualities. The filler fraction to matrix fraction comparison exhibits variations of 50:50, 60:40, 70:30, and 80:20. The particle board production process employed in this study utilizes a cold pressing method, wherein a pressure of 15 MPa is applied for a duration of 120 minutes. The board particles that have been acquired are subjected to testing in order to ascertain their physical characteristics, such as density and water content. The experiment was conducted in compliance with the SNI Standard 03-2105-2006. The flexural strength of particle board was evaluated in accordance with the standard SNI 03-2105-2006. An assessment was conducted to evaluate the susceptibility of particle board to termite infestation, in accordance with the guidelines outlined in the SNI 01-7207-2006 standards.

Abstract

The artificial lighting system is a major component in a building, consuming up to 50% of its electrical energy. Hence, it is crucial to evaluate and identify opportunities for energy savings. Industries involve numerous operational instruments, one of which is building structures with artificial lighting systems. The requirements for artificial lighting systems consider energy conservation principles aimed at achieving energy consumption efficiency during operation. Therefore, a series of energy management activities and energy conservation evaluations are conducted through an audit of the artificial lighting system in a building with 50 rooms (the study object). The audit method used is the Short Energy Audit (SEA) to calculate Energy Consumption Intensity (ECI) under actual conditions (condition 1) and predictions under improvement conditions (condition 2). The results depict an energy usage portrait (evaluation) showing that 100% of electricity consumption is efficient, with the ECI target standard at 2,5 kWh/m2. The percentage saving (PS) in condition 1 are 68,058% and in condition 2 are 64,967%, indicating that improvements will not significantly alter the energy saving opportunities but will provide considerable benefits in operational investment. Recommendations include making small short-term investments in repairs, maintenance, optimizing lighting system operations, and conducting initial energy audits

Abstract

Studies on reclaiming CO2 sand mould waste have the opportunity to increase productivity. This research was conducted to learn further about the potential of reclaimed CO2 sand moulds. The effect of the grain size of the reclaimed CO2 sand mould on the hardness and metal surface roughness was analyzed. In addition, a comparison of casting quality analysis was carried out between products using new sand and reclaimed CO2 sand moulds. The CO2 sand moulds were crushed and then sieved using 12, 25 and 40 mesh sieves. The sand waste grains were reclaimed through a detergent washing process. SEM-EDS characterization was carried out to determine the elements contained. The hardness of the casting product was tested using the Rockwell method with a load of 981 N. Meanwhile, the metal surface roughness was characterized through the Roughness Test and visual identification using the JIS 82 standard. Based on the results of the SEM-EDS characterization, the three variations of the reclaimed CO2 sand have the potential to be reused. The quality of the hardness and metal surface roughness of the reclaimed CO2 sand with 25 mesh size variation is close to the quality of the casting product using a new sand mould.
