Abstract

Stainless steel has good mechanical properties compared to other materials for strength and hardness, usually will experience an increase in hardness after hardening. The purpose of this study was to obtain information about: Value of hardness and strength Impact of martensitic stainless steel annealed with variations in temperature and cooling. The research method used is an experimental method, namely by annealing martensitic stainless steel with variations in temperature and cooling rate. The results were tested for Impact and hardness using the Rockwell C (HRC) method with the category of Research Infrastructure development and science and technology in the field of Mechanical Engineering. The research results are expected to be used as an alternative to improve the mechanical properties of materials, especially in the annealing process. The level of technological readiness to be achieved: 2, because in this study a model is made to test the truth of the basic principle that the hardness level of martensitic steel in annealing is influenced by varying temperatures and cooling.

Abstract

Almost all kids still bring a lunch box and a bottle of water in their bag when they go to school. His mother always prepares a lunch box complete with a drinking water bottle, hoping that his son can enjoy his favorite lunch and avoid starvation. Sometimes the mother is distraught when the child has brought the lunch box, but the water bottle is left behind. Then the mother was willing to take her child's water bottle to her school. This is certainly not expected by either the mother or the child. As a form of concern for the author to this problem, the author proposes a lunch box design with a lunch box lid that also functions as a drinking water bottle. The idea of this design proposal is one grab. Both are food & drink in your hand. The goal is how to make kids can grab their food and drink quickly and practice. So, it is proposed to modify the top cover of the standard food pack to become a drink bag. The design process begins with analyzing market needs, making sketches, creating 3D design models using the Autodesk Inventor application, material selection, and product evaluation.

Abstract

In this study, we discuss a case where the installation of a belt conveyor, which was initially only one line, was then made a new branch that supplies coal to other power generating units. Equitable capacity distribution and continuity of coal distribution are the main focus of this study. Therefore, an automatic control system of coal flow divider on belt conveyor installation was designed. The working principle of this coal flow splitting system is to control the movement of the straight blade plow that directs the flow of coal to each unit at a particular time and continuously. Straight blade plows in the form of steel metal plate with a thickness of about 10 mm in which one end is connected to the end of the pneumatic cylinder. The automatic control system of the coal flow divider in belt conveyor installation was designed using CX-Programmer and CX-Designer applications. CX-Programmer serves to create automatic control logic concepts. While the CX-designer functions to create a Human Machine Interface (HMI). The results of this study are in the form of control logic lines that can be applied to Programmable Logic Control (PLC) devices and Human Machine Interface (HMI) equipment.
