System Engineering Logbook

For this week, we create a system architecture based on our project Automatic Bread Making Machine and present to Sir Zaki during class. The system architecture consists of three types which is functional architecture, physical architecture, and allocated architecture.   Functional Architecture Above shown Functional Architecture table and flowchart of the Automatic Bread Making Machine. From this, it is easy to understand how the machine working from the start with providing a power supply to the machine until the end where the data from the machine is transferred to Cloud.   Physical Architecture The physical Architecture table above shows the list of components used in the Automatic Bread Making Machine project. 12 physical elements of the system in this project.   Allocated Architecture The allocated Architecture table and flowchart show the combination and interaction of Functional Architecture and Physical Architecture. The m...

     For this week, we learned about system architecting  is the conceptual model that defines the structure, behavior, and more views of a  system . An  architecture  description is a formal description and representation of a  system , organized in a way that supports reasoning about the structures and behaviors of the  system .  Architecture is associated with structures, their relationships, and expectation for their design. This applies to complex systems, such as aircraft, power plants, and spacecraft, as much as buildings.       There are three types of architecture. The first is functional architecture. Functional  architecture  is an  architectural  model that identifies system  function  and their interactions. It defines how the functions will operate together to perform the system mission. Generally, more than one  architecture  can satisfy the requirements.  B...

         For  this week, we learn how to using Capella Project during the tutorial period. Dr. Zaki was asking each group member to do the tutorial.  We use this application because it can match the criteria at the end of the project based on the format of Prof. Zul given.           The Capella workbench provides methodological guidance, including an engineering workflow with clear modeling objectives, and an advanced set of productivity tools. It helps us to do the block diagram for our project. We can see the advantages of these applications.                Capella is a concrete illustration of an open and field-proven approach that can solve major concrete industrial challenges. Its creators decided to capitalize on Eclipse Modeling and its ecosystem to implement the adaptable and extensible workbench that could both support the MBSE approach it required and fit the s...

  For this week, Sir Zaki was given to us for researching on startup of the technology machine. This technology machine needs to improve from a Programmable Logic Controller to a microcontroller. The microcontroller would combine with the sensor, Internet of Things (IoT), machine learning or Artificial Intelligence into the project.             A Programmable Logic Controller, or PLC, is a ruggedized computer used for industrial automation. These controllers can automate a specific process, machine function, or even an entire production line. The PLC receives information from connected sensors or input devices, processes the data, and triggers outputs based on pre-programmed parameters. Depending on the inputs and outputs, a PLC can monitor and record run-time data such as machine productivity or operating temperature, automatically start and stop processes, generate alarms if a machine malfunctions, and more. Programmable L...

            In this week we discussed and prepare for proposal presentation next week during the class time. Our team need to propose an microcontroller to replace PLC in industry based on project brief given. The microcontroller must be based on embedded system.            First part of discussion, we brainstorm to come out an idea regarding the PLC issues in industry. Our team agree to propose a replacement of the PLC use in conveyor system in industry.          Second part of discussion, we divide the task for the presentation. Each of team member have they on part to present and prepare the slides. Conclusion: The Proposal Presentation need to have 10 slides and the presentation must not more than 20 minutes based on presentation guidelines that been given in Microsoft Team

           For this week, we were given a task to complete a tutorial on  CE BJT small-signal amplifier. The tutorial is divided into 3 steps. Step 1 is to calculate the dc and ac characteristics of the amplifier in the figure given. Step 2 is to produce an alternative analog design, using op-amps as a solution. For the final step, we do not have to do it yet.           For step 1, we did simulation using multisim software and compare the result with our calculation. Below shows the calculation and simulation result.                    Simulation result for dc characteristics:                    Calculation for dc characteristics:                                                ...

                  Sir Zaki is advising us to get ready for the logbook from week 3 till this week means week 6. We also to be ready the proposal presentation on Week 8. The presentation is about a project that we should apply to transform plc to the next level. Based on the tutorial given by Sir Zaki to us some extent can help us develop ideas in the field of innovation related to ‘PLC Replacement’. Week after week we also improve how system engineering is implemented based on the tutorial that we have received.   For example, we have done that PLC could reduce the human power for making roselle jam and syrup. We would implement the idea as to how open source innovation and extensible software can be 'PLC replacement.' This shows that the criteria that must be present in the project can be met with the weekly tutorials that have been given.
