Abstract

The development of increasingly advanced technology, especially in the health sector, can lead to an increase in the need for composite materials used. This study aims to describe the results of the concentration of KOH solution and the orientation of the ramie fiber on the impact strength of composites with a polyester matrix. This research is an experimental study with the manipulation variables are the concentration of the KOH solution and the orientation of the fiber direction by determining the value of the impact strength as the dependent variable of ramie fiber as a control variable of this study. This study obtained the optimum impact test result of 0.0711 J/mm2 with 5% KOH solution concentration and located at 0o/45o/90o fiber direction orientation. While the results of the lowest impact test resulted in a value of 0.0101 J/mm2 without soaking the KOH solution and located at 90o/0o/90o fiber direction orientation.

Abstract

Fluid is a substance that is capable of flowing. The types of fluids that are often used in everyday life are liquid fluids and gas fluids. To drain the fluid you need a laundry device called a pump. The working principle of the pump is to provide pressure or energy to the fluid. This type of research is experimental research, namely, researchers carry out experiments to obtain data in the form of numbers or quantitative data. Researchers varied the valve openings from 0o, 25o, 45o, and 65o and used a pump rotation of 1600 RPM. This research plan is to determine the effect of valve opening on pump capacity and efficiency. The research results show that the pump capacity and efficiency results at valve openings from 0o to 65o have increased significantly. The greatest capacity and efficiency occur at 65o valve openings with a value of 6 L/M and 43.2%.
