<![CDATA[Thrust bearing yang berfungsi mendukung gaya-gaya yang terjadi pada  pompa Sulzer Bingham Type 8 x 10 x 13 MSD – D 3 Stage akan mengalami kerusakan berakibat kegagalan pula pada komponen lain. Perubahan sifat mekanik disebabkan oleh kondisi pembebanan yang tidak baik, seperti terjadinya kondisi unbalanced dan poros yang tidak sesumbu (missalignment) menimbulakan getaran.Metode yang diterapkan dalam pengujian melalui pendekatan analisis kerusakan thrust bearing 7310 BECBM. Data kerusakan thrust bearing 7310 BECBM didapatkan  frekuensi vibrasi, dan intensitas kebisingan akan dilakukan pengolahan data menggunakan pendekatan frekuensi vibrasi dalam bentuk frekuensi domain menggunakan bantuan software MATLAB.Data pengamatan thrust bearing 7310 BECBM pada 0 – 1225 jam tidak menunjukkan indikasi kegagalan dan indikasi kegagalan ditemukan pada 1663 jam. kerusakan thrust bearing dalam arah horizontal disebabkan oleh kondisi unbalanced. Spektrum vibrasi dalam domain frekuensi terhadap thrust bearing arah vertikal ditunjukkan pada Gambar 7. kerusakan thrust bearing arah vertikal disebabkan oleh fenomena bent shaft atau ketidaklurusan sumbu poros. Frekuensi vibrasi thrust bearing 7310 BECBM arah horizontal lebih tinggi dibandingkan frekuensi vibrasi arah vertikal dan aksial. Komponen cage bearing memiliki sifat kekerasan yang rendah dibandingkan komponen lainnya sehingga cage bearing akan lebih cepat mengalami kerusakan.]]>

<![CDATA[A heat exchanger is a device that is used to change the temperature or fluid phase by absorbing or releasing heat between the hot fluid and the cold fluid. One type of heat exchanger that is most widely used in industry is shell and tube. Optimal heat exchanger performance has an important role to support production stability in various industries. The performance of shell and tube heat exchangers is affected by fouling factors which are the formation of deposits on the surface of the heat exchanger which can inhibit heat transfer and increase the resistance to fluid flow in the heat exchanger. After analysis, it is known that the mass flow rate of the flue gas is 0.06523 kg/s, the effectiveness of the heat exchanger is 66.837%, the overall gross area is 3.317350717 m2, and the effective heat transfer area is 2.211567145 m2.]]>

<![CDATA[The condenser is a critical component in systems designed to condense steam into liquid. The performance of a condenser can be influenced by the rate of heat transfer, vacuum pressure, and effectiveness. The aim of this research is to ascertain the effectiveness value and the variables affecting the performance of the condenser in the distillation process of citronella leaves, as well as to understand the impact of the heat transfer rate on film condensation (condensate steam mass). The methodology for assessing effectiveness values utilized the Log Mean Temperature Difference (LMTD) and Effectiveness – Number of Transfer Unit (NTU) approaches, alongside comparing the condensate steam mass with the steam mass flow rate to achieve film condensation. The research findings revealed an effectiveness value of 89% for the condenser, with 36% of the condensate steam mass converting into bio-oil. Influential variables include a capacity ratio of 0.0182840 and a heat transfer rate of 186,544.68 W. The LMTD was calculated to be 29.74°C. Thus, it can be concluded that the condenser used in the distillation process of citronella leaves still maintains good performance.]]>

<![CDATA[Electric car consists of a chassis that carries the vehicle's load, such as an electric motor to drive the wheels, and a battery as an energy source for the electric motor. Overall vehicle performance is controlled and monitored by the battery and engine controller systems. The objectives of the research on Design and Analysis of Electric Car Chassis Using the Finite Element Method Using Solidworks 2017 can be described as follows: Identifying aspects of the design strength of the AISI 4130 frame (hollow steel 40 x 60 mm). The design determines the wheel alignment of the wheel geometry, the angle of inclination of this wheel will later be used as a reference when making the frame and continues to make the geometry for the wheels and the width of the rear wheel tread. This axle uses a vehicle equivalent axle. Measurement, the rear wheel track of the vehicle axle is 1126 mm, and the front wheel track uses a track with a different width. For easier handling during maneuvers, the wheelbase is fixed at 1835.5mm, so the front front wheel track is wider than the rear wheel track. Mesh on the chassis using tetrahedral as shown in figure 2.a then loading is given to the node point position where the driver is on the chassis supporting the driver's load is 750 N and the battery is added, the weight of the BLDC motor and solar panel is 310 N and the maneuver is 100 N. The simulation results show the voltage value VonMises Stress with AISI 4130 material with a maximum stress value of 2.796 x 108 Pa, right maneuver 3.92 x 108 Pa and left maneuver 4.071 x 108 Pa with a given load of 1060 N. The maximum vonmises stress occurs when the kart maneuvers left while the highest maximum displacement occurs only due to the influence of gravity without being affected by vehicle maneuvers so that maneuvers can reduce displacement.]]>
