WEEK 16: PRESENTATION DAY!

Jeng jeng jeng! Finally the day that has come for the FYP 1 students to present their project to the assessors. This is the first time I wear a blouse which is something that I never done before so new achievement unlocked! šŸ˜‰ hahaha sorry but I just had to mention it since it is a rare phenomenon to see me wearing "lady-like" outfit.

Ehem. So on 22 November 2017 which falls on Wednesday, I, Wan Nur Qistina Binti Wan Shukry, has presented my FYP 1 project. I don't know what happened to Dr. Zaki though as Dr. Gan Hong Seng has replaced him as my first assessor which makes me be among the last FYP 1 students to be assessed. Overall, I think I did a good job presenting my project as both my assessors looks like they satisfied with my explanation on the project and hope it is the same with the results.

Enough with the presentation, I've finally finished my proposal report and i just need to submit it to Dr. to check for the plagiarism.

WEEK 15: Final Preparation of Presentation Slides

This is the only week that I have to show the slides to Dr. and do some correction before the presentation day next week. 


After presenting my slides, Dr. told me to include the drawing of the prototype of my project and state the location to test the prototype in the methodology section besides add a references section at the end of the slide. That is all I need to improves on my slides and I'll be ready for the presentation day.


Other than checking the slides, Dr. also gives a few tips as in what he would asks if he be the assessors on the presentation day. Talking about the assessor, the one who will assess me on the presentation day is Dr. Zaki and Sir Muhyi and you know what, I'm so nervous thinking about the FYP 1 presentation that I dreamed being assessed by Sir Muhyi even before the list of assessors is announced. What a dream comes true! (i guess šŸ¤”)

WEEK 14: Presentation Slides Progress

For this week's consultation, I presents the slide I've prepared to Dr. so that I know if I'm doing it the right way or not. Unfortunately, there is a lot of things that needs correction on the slides along with the report progress especially on the scope and limitation part which I have to state the size of the fish pond and tanks involved.

The proposal report is almost finish as I'm listing all the hardware and software that will be use in my poject.

WEEK 13: Presentation Slides Preparation

The research about this project is done once I’m sure about the hardware and software that I need to complete my project. This week I’m going to starts preparing the slides for the FYP 1 Presentation day which is scheduled on week 16 at Dewan Gemilang. It is supposed to be on week 14, but I was told that it has been postponed to week 16. I don’t know the reasons why it’s being postponed, but I’m quite relieved since I have more time to prepare myself for the presentation day.

Back to the proposal report, I’m still stuck at the chapter 1 as I have to modify the Introduction part because Dr. told me that it is better to include some statistics to make it more interesting to be read. He also reminds to work more on the literature review in chapter 2, to paraphrase it using my own words besides improve the methodology, flow chart and block diagram for chapter 3 so that people can understands it better.

WEEK 12: Proposal Report


Well I’m already in week 12 now so I thought that I better start doing the proposal report before things gets more complicated with the other subject’s assignments and tests. 

I almost done doing the chapter 1 which consists of a few sections that is:
  • Introduction
  • Project Background
  • Problem Statement
  • Objectives
  • Scope and Limitations
  • Significance of the Study
  • Conclusion
I’ll starts doing the chapter 2 after finishing the chapter 1 and submit to Dr. for correction.

WEEK 10: Selecting the Sensor

After done reviewing the journals and doing some research on the suitable sensors to measure the water quality parameters for my project, I decided to use 3 types of sensors, that is: -

a)      Temperature Sensor
       -   To measure the water temperature in the ponds and tanks.

b)     pH Sensor
      -   To measure the pH value of the water as in detecting the chemical factors in the water that makes the water becomes alkali and acidic.

c)      Dissolved Oxygen Sensor
  -     To monitor the oxygen concentration in the water as it is crucial element for the fish to live in the water.

Most important is all of the sensors must be water resistant since it will be used in the water.
