was thinking about iranian ghadir or NK yeoneo or Yugo class , but not so sure , both ship mentioned doesn't have hydroplanes on their conning tower and X rudder .
Look at South Korean, and Chinese midget submarines, apart from the ones they have shared in public in fairs, there are other ones which looks exactly what this company and others claimed to be developin in Indonesia (both SK and China has the one with an X rudder and exact same front elevators and mast, dimensions, range etc). Especially in some specs and features this is too clear, also accounting both countries were at some place in contact to sell such submarines,to Indonesia. Neither of them in contact anymore.
"Tested" for what? , and the design originates from somewhere else still. In 2016-2017 SK has delivered a concept to be developed jointly, i think it is being recycled.

SK doesn't have only one place which designs submarines, the Jang Bogo is not their design either. SK in the past ,also China was in contact to sell midget submarines. Also they (SK) have assisted one beyond conceptual stage, i don't know how further China has gone, which that one from SK is later is recycled into others.
And strangely all from Palindo, BPPT, Terafulk resembles each other in dimension and specs?This is PT Palindo Marine design
Indonesia’s PT Palindo Marine showcases mini-submarine design - Quwa
Indonesia’s PT Palindo Marine showcased its mini-submarine design at Indo-Defence 2016, a 22-metre ship oriented for special forces operations in littoral waters…
hydrodynamic testing laboratory ? like this ? we do have one in surabaya near ITS (surabaya / 10th november institute of technology) which well known with its shipbuilding and naval engineering graduates (surabaya also where PT.PAL is located)
BPPT has cavitation tunnel, towing tank, basin tank. If not tested in those, then it is not a serious project.
I know these, but what i am telling this is not "sufficient" to design it.

And in 2011 PT DI was developing a Light attack helicopter with Korea, if we pull the news from past Turkish AAW Frigate would be in service before 2020 according to the officials in 2007.This is old 2010 news and it is revealed that the program has been started in 2007
=======================================
BPPH IS DEVELOPING CONTROL ABILITY SYSTEM
SUBMARINE
Defense and security issues related to the sovereignty issues of the Unitary State of the Republic of Indonesia (NKRI) are increasingly emerging. To respond to these problems and maintain the sovereignty of the Republic of Indonesia, the reliability and completeness of the TNI's main defense system (alutsista) is needed. ``
As a maritime country, ideally a reliable and complete marine defense system is needed, but this has not yet been realized due to limited funds and the chain effect arising from the embargo. The impact of the embargo has not always been detrimental.
Thanks to the embargo, the spirit emerged to reduce dependence on buying foreign defense equipment, "said the Head of the Hydrodynamics Research and Research Agency (BPPH), Erwandi when met in his office, Surabaya (22/09). Furthermore, Erwandi said that one of the strategic marine defense equipment that is loaded with high technology loads and has a high psychological effect on opponents is a submarine. ``
For this reason, since 2007 UPT-BPPH has collaborated with the Indonesian Navy's Research and Development Agency (Dislitbang) and support from the Ministry of Defense began designing a small submarine with a length of 22 meters and testing its model in tensile test tanks and in wide pool tanks. for experimental maneuvers in the BPPH laboratory ‚. `` In 2010 we plan to design a submarine control ability system.
This system can later play a role in controlling the ship's motion horizontally, vertically, diving, or rising to sea level again. In addition, our future plans will also develop research on the sources of noise from submarine propellers. So with reduced noise on submarines, submarine movements will be difficult to detect by the enemy, 'explained Erwandi. ``
I hope that in the future Indonesia will be able to build its own submarines. This will certainly be a matter of pride for our nation. But indeed the stages cannot immediately make a large submarine, it must be in stages. The most important thing now is that I want to succeed in developing the submarine's control ability system. Because if we already have this control ability technology, then we can make submarines that can be used for various purposes, both for security and tourism defense. It remains how the submarine design will be made, he said. (KYRA / PR)

You may as well know Iranian submarine designs are delivered from N.Korea, and in fact based on what i know, despite of having some key technologies in shipbuilding (they might be having an advanced cavitation tunnel) even their modern submarine designs receive major assistance from China.This is quite respected Defense media in Indonesia. The problem is government doesnt give money to build real prototype yet........
In 2025, BPPT targets the release of a prototype manned submarine with AIP technology

Don't ask for more details about this one project, but it is stated that the Agency for the Assessment and Application of Technology (BPPT) is working on a mini submarine prototype, even this national technology research institute has declared 2025 as the target for the release of a prototype mini submarine ( midget submarine ). .

As Wahyu W Pandoe, Deputy of BPPT for Industrial Technology, Design and Engineering, told Indomiliter.com , "In 2025 it is hoped that the prototype of the BPPT mini submarine will be completed, and this is a full prototype (scale 1: 1) and has been manned," Wahyu said after opening the workshop "Achieving Defense Superiority Through Underwater Defense Technology" held by BPPT and Saab in Jakarta (29/8/2017).
In developing the prototype, BPPT will partner with several overseas manufacturers. "The technology for modern submarine development is quite complicated, for that we invite partners from abroad who have experience to share knowledge in realizing this submarine prototype," added Wahyu. He added that several strategic industries in the country will be involved in this project, namely the shipyard facilities owned by PT PAL, and PT Krakatau Steel which can produce high-quality metal coatings for submarines.
Submarine design by Colonel (Ret) Ir Dradjat Budiyanto MBA.
Although not able to mention in detail, this submarine will have a length of 30 meters and a diameter of 3 meters. Surprisingly, BPPT announced the adoption of AIP (Air Independent Propulsion) on the submarine prototype. Unfortunately, there is no mention of the type of AIP that will be used later. In theory, by transplanting the AIP, the submarine would have the ability to dive about three weeks before the sub would recharge. As the first stage, we are targeting the submarine to dive for two days, only then will the endurance be further developed based on the test results, "said Wahyu.
Basically BPPT is trying to make this prototype manned submarine can perform basic functions properly, such as diving and surfacing without problems. And when asked about how many torpedoes it can carry? Wahyu emphasized that the submarine prototype built for 2025 does not yet cover the aspect of weaponry. "We master the technology first, then the next stage of development is the mastery of the weapon system." Wahyu said closing the interview.
Currently, BPPT already has a hydrodynamics laboratory test facility (Balai Teknologi Hidrodynamics) in Surabaya for testing a submarine on scale model.

In accordance with the vision of Indonesia's maritime axis, ideally the Indonesian Navy needs more than 12 submarines. However, considering the limited budget, plus submarines are known as super expensive defense equipment, it will be very difficult for the government if all the needs of submarines are supplied from abroad. Apart from the construction of standard submarines, procurement of mini-submarines was already projected, especially for carrying out guerrilla tactics underwater in shallow seas. (Haryo Adjie)
Tahun 2025, BPPT Targetkan Rilis Prototipe Kapal Selam Berawak dengan Teknologi AIP
Jangan bertanya lebih detail dahulu tentang proyek yang satu ini, namun disebutkan bahwa Badan Pengkajian dan Penerapan Teknologi (BPPT) tengah menggarap prototipe kapal selam mini, bahkan lembaga riset teknologi nasional ini telah mencanangkan tahun 2025 sebagai target dirilisnya prototipe...
From where you read PT DI is developing light attack helicopter with Korea ??? They are trying to make it themselves but once again government doesnt give money for development cost. It will be based on BEL 412
