Abstract

The biosensor is a sensor device that combines biological compounds with a transducer. One type of biosensor that uses mass change detection techniques are QCM (Quartz Crystal Microbalance). QCM is a sensor that works with the principle of quartz crystal frequency shift due to mass deposition on the surface of the crystal. QCM can be used to detect the reaction between the molecules, so that the QCM can serve as biosensors that can be used for the diagnosis of a disease. In the development of QCM immunosensor for there are many problems, one of which is the construction of the cell. Construction cells can be used as a reaction between biomolecules. Construction of cells made of white Teflon. To keep QCM sensors are not experiencing physical stress that can lead to rupture due to pressure from the Teflon o-ring is used as an insulating silicon. The results of this study indicate that the construction of the cells created can be used as a medium for immobilization of Bovine Serum Albumin observations (BSA) on the surface of the sensor.

Abstract

Carbon dioxide (CO2) has been known well as a contributor gas for the global warming. Regarding the impact, the measurement of the CO2concentration in the air is very important for the assessment. This paper presents the design of a CO2 instrument built by using the components that are available in the market.  The instrument contains a CO2 sensor, an interfacing system, and a computer. The test showed that the instrument worked well. It could be used to measure a CO2 concentration on line and in real time.
