Abstract

Microfluidics devices have been applied in the biomedical field to manipulate the tissue fluids in channels with dimensions between 5-500 lm. Microfluidics device manufactured by a microfabrication process consisting of design, microstucturing and back-end processes. One application of microfluidics is a passive mixing microchannel. In this device, the liquid will flow through the channel without any moving parts and the pressure from the outside to produce a fluid mixing. It is important to design the shape of the channel to generate a nice passive mixing microchannel. Low power CO2 laser is used to process microstucturing as cutting tools to produce microfluidic devices on acyilic material. Surface roughness lines were designed to be observed. In this study, the design process channel carried by the experimental method through the parameters that affect the output of the process is the power of laser cutting, cutting speed and design channel. And then the fabrication of microfluidics with back-end processing is done by the process of merging with a thermal bonding method. Finally, From the experimental results, the design of the channel 1 has an influence on all the parameters for surface roughness compared with a channel design 2.

Abstract

Heat source of the heat energy can affected of the temperature distribution and the boiling temperature of the tapering heat pipe located on the evaporator. The purpose of this study was conducted to determine the effect of heat source on the temperature distribution and boiling temperature that occur in the tapering heat pipe. In this study, used heat pipe tapered shape of the copper pipe diameter of 10 mm and 20 mm as evaporator as condenser with a length of 200 mm. Tapering heat pipe inside there is a wick mesh screen serves as the axis of the capillary to the return liquid / backflow of fluid from the condenser to the evaporator. The condenser ends mounted a valve to inject the working fluid into the tapering heat pipe. K-type thermocouple is integrated with NI-9211 module and c-DAQ 9271 to measure the temperature distribution along the tapering heat pipe with a heat source of DC power supply for (25, 30, 35, 40, 45, 50) Watt. The results showed that there was a difference of temperature distribution and boiling temperature caused by the variations heat source. Temperature of distribution and boiling temperature which tends to increase in value the greater the heat source, so it can be concluded that the heat source has an influence on the temperature distribution and the boiling temperature of the tapering heat pipe with 50 Watt heat source generates temperature distribution and boiling temperature stable.

Abstract

Organic Light Emitting Diode (OLED) merupakan divais fotonik yang tersusun dari katoda sebagai sisi negatif, anoda sebagai sisi positif, dan sebuah lapisan emissive dari bahan organik yang dapat memancarkan cahaya ketika penghantar diberi arus listrik. Karakteristik arus yang dibutuhkan harus sesuai dengan karakteristik tahanan sehingga dapat menghasilkan fabrikasi OLED yang optimal. Teknik laminasi merupakan salah satu teknik yang digunakan dalam pembuatan Organic Light Emitting Diode (OLED) dengan cara menempatkan struktur OLED pada plastik laminasi. Tahun 2015, Adnan Fatahillah Afiff [1] memfabrikasi Organic Light Emitting Diode (OLED) menggunakan teknik laminasi tetapi hasil fabrikasi belum dapat memancarkan cahaya. Ada beberapa hal yang mempengaruhi karakterisasi OLED saat fabrikasi yaitu suhu laminating, waktu ultrasonic cleaning, dan kecepatan rotasi spin coating. Ketiga faktor tersebut akan mempengaruhi karakteristik arus yang dihasilkan dan dapat memaksimalkan fabrikasi OLED. Oleh karena itu diperlukan penelitian terkait pengaruh ketiga faktor tersebut terhadap karakteristik arus listrik pada OLED. Langkah-langkah yang dilakukan adalah menggunakan teknik laminasi dan memvariasikan waktu ultrasonic cleaning, kecepatan rotasi spin coating, dan suhu laminating. Arus listrik yang mengalir pada Organic Light Emitting Diode OLED dapat mencapai nilai paling tinggi pada saat waktu ultrasonic cleaning selama 15 menit, suhu laminating sebesar 130o C, dan kecepatan rotasi spin coating 4500 rpm.

Abstract

The biomass gasification process is a way to obtain combustible syn-gas through combustion of biomass in a closed reactor with the help of air from a compressed blower. Without the help of air gas formation process is not possible, the combustion in the furnace must have air that can start a fire. The tool for supplying air is a pressure blower. The purpose of this study was to obtain a stoichiometric air and biomass mixture in the rice husk gasification process. With the stoichiometric air fuel ratio (AFR) in the rice husk gasification process, it will produce a perfect flammable syn-gas.The method used in this research is to change the rice husk solid through the gasification process. The gas released in the gasification process will be varied at the blower speed with or without using a dimmer. From the test results, it can be seen in the syn-gas output from the reactor. on dimmer 1 the inlet airspeed is 3.5 m / s, on dimmer 2 the airspeed is 4.0 m / s. In dimmer 3 the air velocity is 4.5 m / s and in dimmer 4 the air velocity produced is 5.0 m / s From the results of testing the air velocity of each variation that enters the reactor only air velocity 4.5 m / s and 5.0 m / s or in dimmers 3 and 4 which can produce flammable syn-gas.

Abstract

Replaceable Lip merupakan salah satu komponen habis pakai dengan material Baja Cor Tahan Panas Stainless Steel (Heat Resistant Stainless Steel Casting ) SCH 22. Produk tersebut dibuat di Polman khususnya di Jurusan Teknik Pengecoran Logam, namun masih ada kendala dalam proses pembuatannya. Masalah yang terjadi pada Replaceable lip ini adalah adanya cacat coran berupa porositas atau inklusi dibawah permukaan tuangan. Cacat tersebut dapat diketahui dari permukaan luarnya setelah dilakukan proses permesinan. Umumnya, porositas dalam produk coran disebabkan oleh gas yang terjebak atau akibat dari penyusutan cairan ketika membeku. Selama ini porositas dicegah dengan proses degassing konvensional dengan Aluminium, tetapi belum memberikan hasil yang optimal. Penelitian ini bertujuan untuk menganalisa dan mengatasi kegagalan/ cacat cor yang terjadi pada produk cor Replaceable lip serta mengembangkan material Baja Cor Tahan Panas SCH22 terhadap kualitas produk yang bebas porositas. Manfaat dari penelitian yaitu tercapainya optimalisasi proses degasing dalam penyelesaian masalah cacat, dan prototip produk yang dapat digunakan secara langsung bagi industri pengguna. Metode yang akan dilakukan yaitu dengan membuat spesimen berupa sampel uji dan sampel produk dengan proses pengecoran logam, kontrol parameter proses metalurgi dengan variasi degasing Al dari 0,1% sd 0,4%, dan Temperatur cor yang tetap sekitar 1450 sd 1550oC. Dari kedua sampel dilakukan pengamatan terhadap porositas, kekuatan mekanik dan struktur mikro, untuk melihat pengaruh dari degasing Aluminium.
