Abstract

The infusion system is relatively simple and easy, namely by hanging the infusion bottle on a pole and utilizing gravity so that the infusion drops will flow through the hose and enter until they flow into the veins. In the world of medicine, the use of infusion systems can also be done to enter drugs. The use of this drug must be monitored to ensure the number of doses that have been entered is according to the doctor's prescription with an infusion system. This paper aims to design and manufacture an infusion drip controller with an Android-based telemetry system. The method of this paper begins with designing and using the VDI 2221 method. The main components designed in this paper are the open and closed components of the infusion drop rate. For manufacturing using 3D printing with PLA material. Meanwhile, the measurement results were tested using a measuring cup with a 5 mm scale with ± 0.02 mm of tolerance. The results of this design show that the open and closed tool components are elliptical with an axis in the middle. While the results of the test show a comparison between the required volume and the removal of the tool by 1.2%. The tool can also provide notifications to communication devices when the volume has been reached. So that the tool can be used by following the tolerance rules for infusion and drug intake.

Abstract

The purpose of using natural fibers as reinforcement for composite materials is expected to be an alternative material to replace the used of fiberglass fibers and is expected to be able to increase the quality of water hyacinth fibers and coconut coir fibers. In this study, to determine the best tensile strength value, several experiments were carried out using the determine factor of the fiber volume fraction of 20%, 25%, 30% and the immersion factor with NaOH solution for 4 and 6 hours using a matrix in the form of epoxy resin. The test results showed that the variation of soaking in alkaline solution media (NaOH) for 6 hours with a volume fraction of 30% obtained the best tensile strength results with each type of fiber, water hyacinth fiber obtained the best results of 23.32 MPa while coco fiber the best result was 22.10 MPa.

Abstract

Current leakage in parallel gap single-sided double spot welding tools occurs if the insulation to the mass-body, either from the work table or the drive system, can reduce the current concentration and result in double-sided welding being relatively difficult to carry out or the weld results being poor. Therefore in this research, an experiment was carried out to test the machine how big the effect of leakage current is on the quality of welded joints by comparing the strength of the joint between a system without insulation and a system using insulation using the independent sample t-test statistical method with a confidence level of 95%. The results of the study show that overall the max load for CT 3 to 10 is a mean difference between without and with insulation, although it is not very significant, this is because the shear test data from the group without insulation has quite a high deviation. High deviations also occur in the upper yield data, the strongest conclusion is that providing insulation (or preventing leakage current) provides a more consistent welding result as seen from the results of the shear test data. Only CT 3 has a significant impact on both max load and upper yield.
