Before I started telling the sharing session with Dr. Neill, I first discuss the questions with Dr. Neill. Anyway, my friends often see me having a virtual meeting with Dr. Neill. Then they asked me questions about life in New Zealand. Wow, very interesting ...

Incidentally, I also want to ask how life is there. Before that, I also often shared with Mr. Rama and Ms. Anti about their life in New Zealand. But I also want to ask Dr. Neill to know his perspective. 

                                

During the sharing session. Dr.'s wife Neill (Miss Lina) was also present and sharing with me. By the way, miss Lina is also an Indonesian. So it's great to be able to share too. There are a few things that we talked about: 

The situation in New Zealand

Currently, New Zealand has seen a decrease in Covid cases. But still, civilization applies health protocols. Then Dr. Neill also suggested that in New Zealand you have to equip thick clothes. Because the conditions there are colder when compared to Indonesia. The people there are friendly too and many people come to New Zealand to living.

Cost of living

Dr. Neill and Miss Lina highly recommend preparing for living expenses if you want to live in New Zealand. If I want to study in New Zealand, I should apply for a scholarship to fulfill my life while studying. If it doesn't get fully funded, partially that's fine too.

Education

Because there are many universities there that have international standards. Not a few also people from Indonesia who live there and study in New Zealand. According to Dr. Neill education in New Zealand includes a superior program and is very feasible if you want to continue your studies in New Zealand.

Australian Accents

Often when talking to an Australian there must be a difference in pronunciation. This is because Australia also has accents not only in British and American. So don't be surprised if Talking to Australia feels different because of their accent.

Okee that was our light discussion when discussing the questions of my friends who are curious about New Zealand. Hearing this, I was also quite interested if I continued my master's studies.

 

Back to my final research …

In this session, Dr. Neill discusses more what statistical methods are used when doing final research. I also describe methods that can be applied and that can be drawn into conclusions. I have also discussed this method with my supervisor, namely Dr. Ir. Sri Pujiyati.

First, Linear Regression

Linear regression is a statistical method that tests variable one (X) with its independent variable. Initially, I was going to use this variable, but it turns out that my data specifications are out of sync with the linear regression method. If it is divided into several ping numbers my data will be too much if I use regression. However, if I use simplified data, only 4 data results will be achieved and this is below the minimum data. So I can't use this method

Second, T-Test

The T-test will test the data group and see the effect of the treatment given to the same subject. This method is very in sync with the current state of my data. Tilapia becomes the control variable then the bubble noise treatment will be the influence factor. However, this method still has drawbacks. Because it turns out that my data has three treatments. Meanwhile, the T-test requires only two treatments. So I can't use this method either.

Finally, Analysis of Variance (ANOVA)

A method that looks at the influence of research subjects who have treatment of more than two variables. This method was approved by my supervisor. I started executing and got the results of the calculations that I found from various literacies. These are the results of the data that I have tested using the ANOVA method :

H0: There is no difference in the average TS value of tilapia which is influenced by air bubbles as noise in the measurement, which means that air bubble noise does not have a significant effect on the TS value of tilapia.

H1: There is a difference in the average TS value of tilapia which is influenced by air bubbles as noise in the measurement, which means that air bubble noise does not have a significant effect on the TS value of tilapia.

One-way ANOVA test results that produce the number of squares (SS), degrees of freedom (df), average squares (MS), calculated value (F), probability value (P-value), and critical F value or F table (F crit ) with a 95% confidence interval. The calculated F value of 20.99 is greater than the F table, which is 2.99. If F count> F table then H0 is rejected and H1 is accepted or significantly different. This means that there is a difference in the average TS value of tilapia which is influenced by air bubbles as noise in the measurement, which means that air bubble noise does not have a significant effect on the TS value of tilapia. Air bubble noise has been shown to affect the TS value of tilapia in acoustic measurements.

                               

Dr. Neill asked me to submit the data and statistical analysis that I made. Because he wanted to help and was also interested in testing the results of the data I had obtained. Next will be Dr. Neill e-mailed me for the final result.

 

I think that's all guys, I hope we can finish our research. 

 

See you again
