System Engineering Logbook

 All the potential hazards in the workplace that require machine safeguarding and ensure they adhere to OSHA regulations. Moving machine parts create workplace hazards and potential machinery-related injuries, making machine guards vitally important. The machines consist of three fundamental areas – the point of operation, the power transmission device, and the operating controls.  Machine safeguarding  helps protect workers from preventable injuries in all three areas. Requirements for Safeguards Machine  safeguards  must meet these minimum general requirements: Prevent contact: The safeguard must prevent hands, arms, or any other part of a worker’s body from contacting dangerous moving parts. Be secure: Workers should not be able to easily remove or tamper with the safeguard. Guards and safety devices should be made of durable materials that will withstand normal use. They must be firmly secured to the machine where possible or secured elsewhere if attachment to

         For t esting and simulation, we are using Proteus and Arduino IDE to run the program and design the circuit. The components that we are using are Arduino Uno as the microprocessor, Two DC Motors for the oven and mixing machine motor, and SHT10 for the temperature sensor and humidity sensor and virtual terminal will show the temperature and humidity level. Figure 1: The mixing motor start after the start button is pressed. Figure 2: The mixing motor will stop after a few moments. Figure 3: The oven starts after the mixing machine stop.

           For this week, we design the operational architecture of the automatic bread-making machine using Capella. The steps of the process are followed on the Capella website. The first one is the Operational Entity Breakdown.  The operational actors in this section are the oven and mixing machine. These operational actors are going to interact with the operational entities. On the right is the operational entities. The ingredients below like sugar, salt, yeast, and water are contained in the dough. The next one is operational Capabilities. In this section, the operational capability is named “Make Bread”. Below the operational capability are the operational entities. The operational capability is showing the involvement of the mixing machine and the oven.          Next is the Operational Entity Scenario. In this process,  We define and allocate the activities to the operational entities or actors and then we define all the interactions of the activities. After that is Operational

                   In this week we have discussed for the final presentation on Week16. Also we discussed for the report. Our team need to be ready what we have been propose for the proposal presentation last time.                 First part of discussion with Dr. Zaki was the tentative about the final presentation. Our team is on Friday of presentation. We all agree about it.                 Second part of discussion about the final report on the next week of after presentation. The submission due date is on 5/6/2021.                 In conclusion, we all need to be prepared and complete all the remaining assessments. Just a few weeks from now to be completed. We are hope everything smoothy done.

        For this week, Sir Zul make a briefing about the final presentation and final report on the project of the subject System Engineering. The details as below: Description of tasks for the final presentation and final report   Final presentation ·          From your proposal presentation, revise it if necessary of the system that you are going to develop. ·          You must have an application for your system. ·          Use Capella to perform operational analysis. You must present in the final presentation the operational analysis with as much detail necessary. ·          The other stages system analysis, logical architecture and physical architecture just mentioned briefly in your presentation. ·          Ideally at the end of all the stages you would have developed a model of the system. ·          For our exercise you need to develop a simple model of your system without using the full steps of Capella.   Final report ·          Describe the system

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 material needed
