I've dealt with this exact situation in the past.

Content on Wikia is licensed under the CC-BY-SA license, which means any and all reuse and derivatives must credit the source. The "derivatives" part is the important part here, since translations are 100% derivative.
 * It is allowed with credit.
 * It is not allowed without credit.

When I was in school, I occasionally copied paragraphs from a textbook and applied a thesaurus to it so that the paragraph was unrecognisable. But on Wikia, rewording something completely doesn't mean it's not a derivative.

The first step is the polite step: contact them (using Google Translate) and inform them that they're allowed and welcome to translate content, but that translated content is derivative, and therefore must credit your wiki.

If they do not respond, or do not understand, I usually ask Wikia Staff to help translate, they usually have a helper for each language, however, "Helpers" are not staff, and do not always understand Wikia policies themselves.

You can also simply edit their wiki yourself, adding a CC-BY-SA template and a link to your wiki - however, I suggest you leave them a message first, so they understand why you're doing this, and do not think you're just spamming. They may still think you're spamming and block you.

However, since it is their legal responsibility to link to the source, they should have to add it, not you. But I find it helps to do it on at least one page to help them understand what they need to do.

You are also within your rights to simply remove the derivative content by blanking the page - but they may block you.

If contacting them yourself fails, then it's time to involve Wikia Staff. The first thing you need to do is prove what has occurred, so find some clear examples how the content they have plagiarised: not always easy with translations. What I usually do is find tables, templates, and lists, in which the formatting is retained, and it's easy to see that the words have simply been translated.

If you're blocked due to attempting to enforce the licensing requirements, Wikia Staff may or may not decide to unblock you. But even if you're blocked, the Indonesian Wiki is still required to abide by the license, you will just have to inform Wikia Staff of every occurrence.
