Here my respond on the video
Making airplane consist of 2 part which is design phase+ production
( aerostructure parts + system integration + assembling ) + Testing phase
That Korean engineers mentioned about 40 Indonesian engineers that are currently in Korea
. They are in majority are technicians who are now in Korea to learn about production of fighter planes where we have to acknowledge that Indonesian Aerospace doesnt have much experience on it, despite Indonesian Aerospace is involved in refurbish and upgrade program of Indonesian F16 A/B in Falcon Star program. They are sent to Korea since August 2021. The news can be seen in KFX/IFX thread, I also put the photo of them on the thread, they are young and look like sending young technicians are intended for regeneration program.
The number should be around 100 in the end of 2021 but we know the number is a compromise since defence minister hasnt pay their financial obligation during that time. There is no budget as well to send management team to Korea as before we had them there. It is Defense Ministry program by the way so the budget should be from them.
Korean has experience in fighter production
Korean has made American fighter like F16 for many years, it is right. Korean has huge experience in production of the fighter aircraft.
In term of manufacturing the fighter planes we are indeed learning from Korean. And from the technicians we send to Korea they are young ones, which means we send them to study there.
In term of design of T50 Golden Eagle/ FA50 they get huge helped from Lockheed Martin and according to Indonesian design engineer that I know who are involved in KF21 program, Korean buy Lockheed Martin design on FA50, so basically the design is the work of LM design engineers. Of course Korean engineers are also involved in the program but I believe they are there to learn. That is what I know from Indonesian engineer that I know that have also been in Korea. As we know, LM can also manufacture T50 Golden Eagle in USA as they are proposing it before to be inducted into US Air Force where the tender winner is Boeing.
For design phase Indonesian Aerospace is reported to have 114 Indonesian design engineers there as July 2019 which is reported by Korean media Yonhap in October 2019. Indonesian design engineers went back home in March 2020, after design phase is completed in September 2019.
Indonesian Aerospace has already worked for KF21 program since the start of program (Technology Development Phase) in 2011
that also produce 2 design which is one of them (C103) has become basic design for KF21. C 109 is a refinement of C103 design. During first development phase there are only ADD Korea and Indonesian Aerospace + ITB (one of Indonesian state university) + some Indonesian Airforce pilots.

"Despite such a delay in payment, the Indonesian side has continued to send its researchers to South Korea to take part in the development process," Rep. Kim Joong-ro of the minor opposition Bareunmirae Party said during a parliamentary audit into the administration, voicing concern about technology leaks.
As of July, 114 Indonesian engineers were sent to South Korea to work with Korea Aerospace Industries Co. (KAI), the country's sole aircraft manufacturer, to design and make a prototype of the fighter, according to a DAPA official.
Last month, DAPA confirmed that the design for the combat jet met all military requirements, allowing the project to go on to the next phase of constructing a prototype.

Indonesian Aerospace is an airframer, similar like Boeing and Airbus, they dont make core technology like radar system and others, so in term of TOT it should be related to something related to airframer and for this KF21/IFX program it is very clear that TOT is about the airframe as KF21/IFX used advanced airframe. Here we can see in this
All of testing data will be shared to Indonesia, so it is not really a problematic to have the fifth prototype tested in Korea with Indonesian test pilots and some engineers that have already been there. Data related to system integration and system upgrade will also be shared. But of course with how Indonesian government behave which its payment contribution makes Korean needs to be careful and dont just give all the data before the payment is completed which is reasonable.
What we can learn from the interview
The interview is conducted 3 months ago before Indonesia restart the payment again around October-November this year as reported by Yonhap and other credible Korean media publication. It is for the consumption of Korean public who has reasonable resentment toward Indonesia government that is not serious on the payment commitment.
The interview in my opinion is intended to calm Korean public over possible Indonesian government never paid the cost until the development is over. So basically there is tendency of the Korean program manager to calm Korean public (who are not Aerospace engineers) over the possible Indonesian pulling out the program and he also try to make Korean public tolerate the present of Indonesian engineers amid Indonesian hasnt paid its financial contribution for almost 3 years.
More about Indonesia participation in KF21/IFX program
This is thread about KF21/IFX program with Indonesia perspective and Indonesian media coverage using only credible media sources. There will be IFX prototype (KF21 prototype 5) being launched soon inshaAllah, so this thread will likely discuss Indonesian KF21 version. IFX prototype will be...
