Abstract

The number of energy demand these days is very high. This shows the need for new inonovation to solve the problem of energy needs, one of which is the use of Phase Change Material (PCM) as a heat exchanger material. The purpose of this research is to know the characteristics of PCM with addition cooking oil and paraffin. The percentage of cooking oil and paraffin are 30%, 40%, and 50% of total volume. The research was start with heating process during 1 hours with temperature ± 25oC. Result of this research shows PCM paraffin - cooking oil with 50% mixture is the best cooling speed PCM, next is PCM paraffin - cooking oil 40% mixture, and the last is PCM paraffin - cooking oil with 30% mixture. On the cooling process, the 30% cooking oil mixture can hold the temperature longers than the other, while the 40% cooking oil mixture has second position, and the last is 50% cooking oil mixture. The conclusion is the addition of cooking oil can improve thermal conductivity of PCM.

Abstract

Dinamika gaya longitudinal kereta api merupakan sebuah sistem persamaan diferensial dengan mengabaikan gerakan lateral atau vertikal dari gerbong pada persamaan, pemodelan, dan simulasi longitudinal kereta api. Penelitian dilakukan pada sebelas rangkaian kereta api menggunakan perangkat lunak Universal Mechanism dengan memodelkan sebuah lokomotif tipe CC300 yang dirangkaian pada sepuluh buah gerbong barang tipe KKBW. Tujuan dari simulasi untuk mengetahui letak gaya coupler maksimum (FCoupler) yang terjadi pada perangkat koneksi rangkaian gerbong barang ketika melalui lintasan berbentuk S, radius 300m dengan kemiringan 0‰ dan 6‰. Penelitian selanjutnya perlu menganalisa simulasi dengan menggunakan model Train 3D pada posisi rangkaian kereta yang memiliki gaya coupler maksimum dengan memperhitungkan gaya vertikal dan lateral yang dialami. Pembuatan spesifikasi teknis kereta berangkaian yang didapatkan dari hasil simulasi dan pengujian lapangan dianggap perlu dalam menentukan jumlah dan panjang rangkaian kereta sesuai spesifikasi lintasan di Indonesia.

Abstract

Nanoparticles are particles that have a size of nm and a size range of 1-100 nano. These particles are formed by the DC Thermal Plasma method. This study utilizes a 70 ampere DC Plasma cutting machine as a plasma flame. The combustion process is carried out in a reactor tube, and the material processed is Aluminum powder (Al) with a purity of 92.5%. The input mass of Aluminum powder is injected at 5gram. Burning process (15 seconds). The particles attached to the reactor wall are sucked in with the help of a vacuum pump then collected on the filter tube. The material is measured by mass using a digital scale. Analysis of the data used is using the Taguci L27 method. The parameters used in this study are injection angle with 3 variations (45 °, 60 °, 90 °) and fire length with 3 variations (2.31 cm; 3.87 cm; 4.28 cm). The contribution of machining parameters in the manufacture of alumina nanoparticles is significant, namely the injection angle parameter has a contribution of 37% and a fire length parameter of 4.2%. The results of the study are generally influenced by the injection angle. The optimum injection angle is 45 ° with an average of 3.56 grams and the least productivity is the injection angle parameter 90 ° which is equal to 2.17 grams The conclusion of the study is that the greater the material injection bend angle the less productivity of DC Thermal Plasma devices as well vice versa.

Abstract

Success in the injection molding process is seen from the results of products that do not produce defects. Warpage defects are one of the defects resulting from the injection molding process. One way to measure warpage defects is to use the ImageJ application. The data processing stage in this study uses the Taguchi method statistical method with two independent variables namely holding time and mold temperature, each of which has three factors and repeated data three times, which aims to obtain more accurate values. The results showed a very influential variable is the holding time parameter then the mold temperature parameter. The higher the level of holding time parameters, the smaller the result of warpage defects. Unlike the holding time parameters, the best mold temperature parameters at the middle level, the result will be a small warpage defect produced. The experimental results of the highest level value on the holding time parameter are 15 seconds while in the mold temperature the value of the middle level is 50 ° C which produces a defect of 1%. While the lowest holding time parameter value is 5 seconds and the highest mold temperature level parameter value of 70 ° C is the worst variation of parameters because it produces a defect of 22%.

Abstract

Harvesting energy merupakan sebuah teknologi yang digunakan untuk mengumpulkan energi dari satu atau lebih sumber energi disekitarnya dan mengkonversi menjadi bentuk energi lain. Vortex-Induced Vibration (VIV) merupakan harvesting energy yang memanfaatkan fenomena getaran yang diinduksikan oleh vortex untuk mengkonversikan energi mekanik menjadi energi listrik dengan memanfaatkan gerakan osilasi bluff body. Penelitian ini bertujuan untuk mengetahui pengaruh jari-jari sudut bluff body terhadap getaran mekanik yang di induksikan, kestabilan osilasi bluff body dan tingkat resonansi getaran. Metode penelitian dilakukan dengan metode eksperimen menggunakan wind tunnel untuk mengetahui pengaruh bentuk bluff body terhadap getaran mekanik yang diinduksikan oleh vortex sebagai penghasil tegangan listrik untuk mendeteksi getaran yang dihasilkan. Penelitian ini memvariasikan jari-jari sudut bluff body dan juga kecepatan angin dimulai dari 0,5 m/s sampai 3 m/s. Hasil penelitian menunjukkan jari-jari sudut bluff body sangat berpengaruh terhadap getaran mekanik yang di induksikan oleh vortex di belakang bluff body. Semakin kecil jari-jari sudut bluff body semakin besar amplitudo getaran yang dihasilkan. Amplitudo tertinggi diperoleh dengan variasi jari-jari sudut bluff body 5mm. Untuk kestabilan osilasi tidak dipengaruhi oleh jari-jari sudut bluff body. Dari grafik hasil penelitian, bluff body berosilasi pada area osilasi yang tetap dan tidak tumbuh ataupun berkurang tanpa batas sehingga bisa dikatakan osilasi bluff body stabil.

Abstract

Centrifugal blowers are machines or tools that are used to increase gas pressure or suction with a final pressure not exceeding 2000 Pa. The impeller blade is the most important part of the centrifugal blower which influences the performance of the blower. The rotation of the electric motor that is connected directly to the impeller is something that can affect the performance of the blower. Honeycomb is a component that is used to obtain fluid flow that is in the same direction, uniform, and stable. This study observed the effect of the number of blades on the performance of backward type centrifugal blowers using honeycomb and without the honeycomb. Variations used are the number of blades 13 and 15 using honeycomb and without the honeycomb. Tests were carried out at 400 rpm, 500 rpm, 600 rpm, and 700 rpm. From the results of the study, it was found that the fewer the number of blades, the higher the performance of the blower. Giving honeycomb at the output blower produces a more fluid or even fluid flow. In blade 15 the data distribution value is closer to the average value indicated by a smaller standard deviation value. This is due to the design of the blade impeller between the blades more tightly so that the air produced will be more tightly or evenly distributed, but has a lower wind speed.
