Abstract

In a power plant unit whose main fuel is coal, there is generally use a belt conveyor installation. This conveyor belt serves to supply coal from the crusher unit to the combustion chamber of the power generation unit. 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, a design of 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 plough that directs the flow of coal to each unit at the certain time and continuously. Straight blade plough in the form of steel metal plate with a thickness of about 10 millimeters in which one end is connected to the end of the pneumatic cylinder. Automatic control system of coal flow divider in belt conveyor installation 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), making it easier for operators to control the course of the coal supply process. The results of this study are in the form of control logic lines that can be applied to Programmable Logic Control (PLC) device and Human Machine Interface (HMI) equipment.

Abstract

Almost of kids in the world still bring a lunch box and a bottle of water in their bag when their go to school. His mother always prepares a lunch box complete with a bottle of drinking water, hoping that his son can enjoy his favorite lunch and avoid starvation. Sometimes the mother is very worried when the lunch box has been brought by the child 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 ones grab, both are food & drink in your hand. The goal is how to make a kids can grab their food and drink easily and practice. So it is proposed to modify a top cover of common foodpack to become a drink bag. The design process begins with analyzing market needs, making sketches, creating 3D design models using the Autodesk Inventor CAD application, material selection, and product evaluation.

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.
