Abstract

The development of the "Kerr Effect" device has been carried out to measure urine glucose levels of Diabetes Mellitus (DM) patients by applying an external electric field of two parallel plate capacitors. The purpose of this research was to design and construct a new "Kerr Effect" device to measure urine glucose levels of DM patients, to determine the effects of external electric fields and glucose concentrations on light polarization. The measurement of the polarization changes was done by emitting polarized light through a glucose standard solution sample and urine samples of DM patients. In this measurement, the sample was irradiated with an external electric field (0 kV / m - 80 kV / m) of parallel plate capacitors, and the changes of light polarization in the sample were observed. The obtained data of the measurement have been collected and plotted as a graph. The results showed that as the electric field increased the changes in polarization have a tendency to increase. In addition, the amount of glucose concentration in the urine also affected the magnitude of the change in the rotational polarization angle of the light. Therefore, the changes in the rotational polarization angle increase linearly due to the influence of the external electric field and the concentration of glucose in the urine.

Abstract

The increasing number of traditional boats made from wood can cause the forest to be deforested. Besides, it also results in scarcity and an increase in the price of basic wood materials so that production costs are increasingly expensive—also, the factors of decay by mould, heating, weathering. One of the efforts that can be made in the traditional shipbuilding process is through making boats made from cheap and high-quality E-Glass fibre laminate composite boards. The purpose of this study was to determine the effect of volume composition of E-glass fibres and scallop shell particles on the tensile strength of hybrid composites. Making hybrid composites by mixing scallop shell filler, E-Glass fibre and matrix. Percentage volume fraction 0C: 0E, 10C: 20E, 15C: 15E and 20C: 10E. The results showed that the maximum tensile strength at the volume fraction of 10C: 20E was 34.15567 MPa, this result was higher than the maximum requirements set by BSN in 2006, namely 0.304 MPa. The existence of a strong bond between the fibres and the matrix can increase the tensile strength of the composite as well as the influence of the scallop shell particles which can help the matrix to accept external loads/stresses so that the composite strength increases.

Abstract

The purpose of this study is to ascertain how changes in the volume proportion of banana stems affect the composite's mechanical characteristics and microscopic structure.  Banana stem fibre served as a natural reinforcement in this investigation together with a polyester matrix.  The selection of banana stem fibre was based on its broad availability and possible mechanism.  The hands lay-up approach is used in this study.  The volume proportion of banana stem fibre was varied from 0% to 25% in order to mould each sample into a composite.  A two-hour alkalisation treatment with 5% NaOH was applied to banana stem fibre. A Universal Testing Machine (UTM) was used to assess the samples' tensile strength, and an optical microscope was used to examine their microstructure.  According to the study's findings, the tensile strength values of composites with volume fractions of 0%, 10%, 15%, 20%, and 25% were 5.9 Mpa, 11.9 Mpa, 8.9 Mpa, and 7.9 Mpa, respectively.  It is evident that the sample with the best tensile stress value, 11.9 Mpa, has a 15% banana stem volume fraction.
