Abstract

This research examines the shift from steam turbines to electric motors for powering the fan drive in a hydrocracking unit's fractionator. While steam turbines have traditionally been valued for their high power output and versatility, they come with significant downsides, such as oil and steam leakage, complex maintenance needs, and low reliability due to wear and tear. Additionally, their long startup times can hinder productivity. To address these issues, the study evaluated the use of electric motors as an alternative. The findings revealed that electric motors, three-phase induction model such as the ILA7 131 and ILA7 166, offer benefits like simpler maintenance, higher reliability, and faster startup times. By adjusting the gear transmission ratio to 8.26 and 13.36, these motors can effectively meet the necessary fan torque and performance requirements, thereby improving the overall efficiency and reliability of the hydrocracking unit.

Abstract

Indonesia is an earthquake-prone country related to its geological position located in the Pacific ring of fire. Therefore, it is necessary to mitigate earthquake disasters so as not to cause much loss, both property and life. One of them is by introducing the walls of earthquake resistant composite house (RKTG) made from sandwich composites. The purpose of this study was to investigate the effect of matrix and skin thickness on the mechanical strength of sandwich composites with polyurethane cores.). Sandwich composites use variations of glassfiber reinforced polymer (GRP) and glassfiber reinforced concrete (GRC) skins and variations in skin thickness of 6 mm and 10 mm. The adhesive used is polyester resin with methyl ethyl ketone peroxide catalyst. The manufacturing process of making sandwich composites uses the hand lay-up technique with a sandwich composite thickness of 10 cm. The results showed that GRP skins have better mechanical properties than GRC skins. Skin thickness can also improve the mechanical properties of sandwich composites. The best mechanical strength was obtained in the GRP skin type with a skin thickness of 10 mm, namely a flexure strength of 1.63 MPa, a compressive strength of 10.7 MPa, and a tensile strength of 0.08 MPa.

Abstract

This research is driven by the need to develop conductive materials that can be applied to sensitive and responsive sensors. Polyaniline-based sensors offer potential solutions for a variety of applications, including gas detection, medical imaging, and environmental monitoring. However, to optimise sensor performance, a deep understanding of the factors influencing polyaniline conductance is required. The object of this research is the synthesis of polyaniline nanofibers using the interfacial polymerization method with frequency variations. Capacitance and conductance testing uses inductance, capacitance, and resistance measuring instruments (LCR meters). The characterization results show that variations in voltage frequency have a significant impact on the conductive and capacitive properties of the nanofiber. An increase in frequency causes a decrease in capacitance at high frequencies. The highest capacitance value is at a frequency of 1 kHz, namely 149.9 pF, while the highest conductance value is at a frequency of 100 kHz, namely 134.64 siemens (1/ohm). The conductivity of polyaniline nanofiber shows a positive influence, with increasing conductance values at higher frequencies. This increase shows that the size and morphology of the nanofiber indicate the nanofiber's ability to conduct electric current. These results provide deep insight into the influence of frequency in controlling the conductive properties of polyaniline nanofibers, which can be applied in the development of sensors, flexible electronic devices, and other fields that utilise polymer conductivity. Key words: frequency, capacitance, conductance, polyaniline nanofiber.

Abstract

Vehicle exhaust emissions are the second largest cause of pollution after industry. Therefore, the government is targeting net zero emissions by 2060. One way to reduce fuel consumption is to use biodiesel. However, the use of biodiesel still has many negative impacts on vehicle performance, namely decreased engine performance. One way to reduce exhaust emissions without reducing engine performance is by adding hydrogen gas. This study was conducted with a simulation to determine the phenomena that occur in the combustion chamber of a single-cylinder diesel engine including hot cylinder pressure, the impact of combustion on exhaust emissions. The stages in this study consist of pre-processing, processing and post-processing. The results of this study indicate that the addition of hydrogen gas can increase the heat in the combustion chamber, the impact of increased heat is an increase in cylinder pressure, combustion chamber temperature, NO emissions, and CO emissions. While HC and soot emissions decreased with the addition of hydrogen gas to biodiesel fuel.

Abstract

Reciprocating Blow Molding adalah proses pembentukan plastik yang menggunakan udara bertekanan untuk membentuk tabung plastik berongga (parison) ke dalam cetakan. Mesin ini biasanya membuat barang-barang berongga seperti botol, jerigen, dan tangki bahan bakar plastik. HDPE biasanya digunakan, tetapi bahan daur ulang (regrind) juga bisa menjadi pilihan. Mencampur regrind dengan HDPE murni dapat menurunkan biaya material dan mengurangi limbah. Produk yang lebih ringan juga menghemat biaya dengan menggunakan lebih sedikit bahan. Faktor lain yang mempengaruhi berat produk adalah shotsize, yang mengukur jumlah bahan cair dari ekstruder. Penelitian ini bertujuan untuk menguji dampak komposisi regrind HDPE dan variasi shotsize terhadap berat botol 190 ml yang diproduksi dengan reciprocating blow moulding dan untuk menemukan parameter yang optimal untuk variabel-variabel ini. Dengan menggunakan response surface methodology (RSM), penelitian ini menemukan bahwa komposisi regrind sebesar 17,50% dan shotsize sebesar 3,58 inci menghasilkan berat produk sebesar 11,55 gram.

Abstract

Surface roughness resulting from the machining process is an important part in determining the quality of the workpiece. In an effort to increase effectiveness and quality in making products using the lathe process, research to determine the surface roughness value of the lathe process is very necessary. In this research, the lathe process was carried out by setting variations in spindle speed and variations in feed motion and a fixed cutting depth of 0.5 mm. The spindle speeds used are 370 rpm, 540 rpm & 800 rpm. Meanwhile, the feed speed used is 0.05 mm/rev, 0.10 mm/rev & 0.20 mm/rev, so the feed speed used in this research is 18.5 mm/minute, 27 mm/minute, 40 mm /minute, 80 mm/minute & 160 mm/minute. This research uses ASSAB 709/SCM 440 material because this material is a medium alloy steel which is often used to make spare parts for both industrial and automotive machines but its application requires different roughness values - different. In this study, the surface roughness value resulting from the turning process from variations in feed speed & machine spindle speed was measured using a Mitutoyo SJ 210 roughness measuring instrument.The results of the lathe process with variations in feed speed & machine spindle speed using ASSAB 709/ SCM 440 material which were measured using the Mitutoyo SJ 210 surface roughness tester, the best average roughness value obtained was 0.354 Ra or the equivalent of N5 using the spindle rotation speed parameter 800 rpm and feed speed 40 mm/minute

Abstract

One of the first steps in order to utilize ocean waves as electrical energy is to create a medium that can be a means of observing wave characteristics. In this research, a laboratory-scale flap model wave tank was designed. Wave tanks can minimize the use of time and cost in the development of technology that uses ocean waves as a source of energy. The purpose of this research is to design a wave tank with a flap model wave maker, and determine the length and height of the waves produced. This laboratory scale flap model wave tank has a size of 150 cm x 35 cm x 35 cm and uses an electric motor with a power of 200 Watts. The wave tank can work with 22 Watts of electric power and an electric motor rotation of 120 rpm. The maximum height of the waves generated from the laboratory-scale flap model wave tank is 4 cm, while the maximum measured wavelength is 36 cm with a volume of 15% water from the full capacity of the tank.
