There's just way too many diffs to point out (the Editor Interaction Analyser says it all really), but if you look at both of their accounts, they have a huge overlap in interests most notably on Malaysian topics and foods that originate from South East/East Asia. Their user page comes off as extremely similar as well, with Awanama putting just "Hi" while Hati Kama has "Hello World". In addition, both usernames end with -ama.
They both seem to engage in very similar nationalist POV pushing, constantly adding stuff relating to Malaysia on topics which are contentious on the connection to the latter. The account Awanama was also previously blocked twice by Drmies, first for 31 hours and then a week for personal attacks. I matched the dates and it seems like their sock, Hati Kama, was created around the time when their master account was blocked for the 2nd time.

Diffs
I think the most clear cut diff that links the two account together is on the article Roti canai, where both accounts reverted the same exact diff (+edit warring) with just 4 hours separating the two. IP 202.166.49.156 (who made the initial same diff) could possibly be Awanama logging out too.
This sort of behaviour is prevalent in many other articles where both accounts frequent, most likely to create an illusion of support.
On the topic of their previous personal attack blocks, I hope users such as Austonesier, Gunkarta and Ibra Bintang can help me out here as I'm not well versed into what happened prior to my suspicions, but so far this is the general idea. However I'm confident that Awanama is currently engaging in sockpuppetry possibly to ward off scrutiny after being previously blocked twice. ShelteredCook ( talk) 06:21, 1 December 2020 (UTC)

I do agree with ShelteredCook's suspicion. I did suspect that Hati Kama was Awanama's sockpuppet, highly possibly as a block evasion sock, also some edits made by several un-login ip addresses. However, I just stand back and see how this will develop, anticipating whether in the future another edit wars will took place. I think Awanama is rather quite careful now, but cunning and dishonest at the same time, compared to his recklessness and tantrums in the past. However, I do not appreciate how he deleted/blanked his past talkpage here and here, as if the past accidents, warnings and disputes never happened; which put a question on his credibility. Thank you for pointing out this problem, Please go ahead on this sockpuppet investigation. Gunkarta talk 11:40, 2 December 2020 (UTC)
New user trying to revert back to revisions made by user:Awanama on Malay gamelan and continuing an edit war, who has been found of using sockpuppets. Possible block evasion sockpuppet. Within 48 hours of Xcelltrasi reverting an edit by Awanama, Satria Aji Anggara comes to revert it which seems too much of a coincidence to me. Pahunkat ( talk) 11:46, 13 December 2020 (UTC)

Restoring edits made by the sockpuppeteer Awanama. here is MrCattttt's edits restoring Awanama's edits. Similar edits and scope of interest with Awanama, very nationalistic driven edits to put Malaysia first, persistent edit wars in the article nasi goreng, which is very Awanamish here, here, here, here, here, here, and here.

Clear Awanama sock. Restoring edits made by the master and their socks (such as Hati Kama) on all their targeted articles. There might be more potential sleeper accounts as well. Gardeenshine ( talk) 12:26, 30 April 2021 (UTC)

It is a baseless accusation. Everyone is watching the Olympics game right now, it is normal for Wikipedians to update sport wiki pages at this moment. The articles you mentioned has a history of edit warring but you cant assume there is only one editor who is interested to improve that page. Again, Olympics. I acknowledged that we had a clash the last few days, but you don't provide any evidence for your claim right now. Wikipedia is not a battleground and Wikipedia:Assume good faith.
