Lately, both here on this forum and on the HTLAL, there have been a couple of questions concerning the availability of resources for studying Indonesian. While I have not studied the language, I thought that it might be timely to create a separate discussion thread to which other members might wish to add their own comments and recommendations. Here is what I have so far:
A G-Search of the HTLAL, using "Indonesian" as the sole criterion yields in excess of 2,600 discussion threads. For the purposes of this file, I have attached the links to Indonesian Language http://how-to-learn-any-language.com/forum/forum_posts.asp?TID=2929 and to Malay and Indonesian Resources http://how-to-learn-any-language.com/forum/forum_posts.asp?TID=17731.
Indonesian Series by Cornell University (John Wolff)
Some years ago, Cornell University published a series of texts by John Wolf. I suspect that the course employed the audio-lingual method or a modified version of it. The course was very well received. Unfortunately, according to some of the customer reviews on Amazon, there was a technical issue with the accompanying DVD that contained the audio files. I do not know whether or not this issue was ever resolved. I suggest that anyone interested in learning Indonesian, send an Email to Cornell and ask them about this problem. From my brief research, here is a list of the materials, which can be found on Amazon, AbeBooks, the Cornell University Press, and elsewhere:
Beginning Indonesian Through Self-Instruction (Books 1,2,3)
Sentence Patterns of Indonesian
Addendum: After posting most of the content of this particular discussion thread, I continued searching the Internet and I came across the textbook "Sentence Patterns of Indonesian" written by Soenjono Dardjowidjojo, published by PALI language Texts: Southeast Asia, University Press of Hawaii, 1978. 434 pages, and which sells for about 20 $US. One seller provides the following description: "Comprehensive presentation of the linguistic system of Indonesian, intended for use in first and 2nd year courses. Despite an initial appearance of being easy to learn, Indonesian has a complex system of affixes that must be mastered before acceptable sentences can be constructed. A major effort of this book is therefore devoted to providing understanding of these affixes, especially those used to form verbs and nouns, and their ramifications in sentence construction. The author's approach to understanding is oral-aural; patterns of structure are immediately followed by extensive drills and other exercises after being introduced. Each chapter also includes sections on pronunciation and useful notes on behavior according to Indonesian culture patterns.". I continued my search of this title and it appears that the University Press of Hawaii offers the audio cassette tapes for the astonishing sum of 500 $US, which I suspect is an old entry that someone in their Sales Department has forgotten to delete or otherwise update. I would assume that an enquiry to the university would clarify matters, including the availability of the recordings via some other media and current pricing. Addendum: In late January 2016, I inquired of the University of Hawaii Press whether the audio recordings might still be available as cassette tapes, CDs, or MP3 files and was advised that they no longer exist.
Teach Yourself Complete Indonesian
Generally speaking, users of the Teach Yourself courses submit positive comments and this seems to be the case for the Indonesian course. As you might be aware, these courses offer a very basic introduction to a given language, aiming for the A1 level. However, a number of customer reviews on Amazon mention that the CD audio track numbers as printed in the course book are not well-synchronized with the actual tracks on the CD! I do not know whether or not this problem was resolved by the printing of a new book or the issuing of new CDs.
Routledge Colloquial Indonesian
Generally speaking, the Routledge Colloquial series has been well received, provided that the students understand that the publisher has deliberately limited the scope of their courses to meet the basic needs of a traveller; that is, get in, conduct your basic affairs, get out. The customer reviews on Amazon are about three stars and the complaints seem to be that some vocabulary used in some of the dialogues is not introduced until later in the book. I consider this to be a minor issue.
Pimsleur offers a Phase I course (30 units) for Indonesian. Their courses are known for their ease-of-use and, generally speaking, I have been very pleased with them. In my view, this course would represent an interesting and low-stress opportunity to "develop a feel for" the sounds and the rhythm language. However, given its high price, the lack of a glossary, and the fact that one must infer the grammar from the lessons, I do not think that this would be my first choice.
The customer reviews of Assimil L'Indonésien on Amazon.FR are, for the most, very positive and the average score is around 4.5 stars. Regrettably, the course appears to be available only in French. Still, were one to acquire a basic knowledge of Indonesian through the study of some other course, the Assimil course could be used as a set of "similar to native materials" wherein the dialogues would be used as practice materials.
DLI Basic Indonesian
Unfortunately, the old DLI Basic Indonesian course is not listed on the JLU-archives website. By searching the ERIC website, I came across most of the textbooks for the course. http://eric.ed.gov/?q=indonesian+basic+course AND http://eric.ed.gov/?q=indonesian+basic+course&id=ED024955. I presume that this course would have used the audio-lingual method of instruction; that is, dialogues, basic sentences, sentence-pattern drills, narratives and readings. As you might be aware, some individuals continue to offer their own collections of the old FSI and DLI courses, for modest prices, on EBay and elsewhere. I located the following offer which, from reading the course description and looking at the onscreen images, leads me to believe that it is, indeed, the DLI Basic Indonesian course or, at the very least, something similar from the early 1970's. http://www.ebay.com/itm/Learn-Indonesian-Indonesia-Language-Training-Course-Guide-/190619231695?hash=item2c61caa5cf:g:caQAAOxyV85RyyRA.
DLI GLOSS Indonesian Files
Although not a course, the DLI GLOSS website contains a few hundred lessons and exercises on the Indonesian language. My experiences and those of other students are that the GLOSS files are excellent for practicing a given language.
Linguaphone used to sell an Indonesian course that is now out-of-print. I am not at all aware whether this was one of their rather Spartan efforts from the 1950's or one of their more complete efforts from the 1970's.
Indiana University CeLt
The Indiana University CeLt Recorded Archives contain the recordings for an old Indonesian Basic Course: http://www.iu.edu/~celtie/indonesian_archive.html. I have given a quick listen to the initial lessons and I can confirm that this is most definitely an audio-lingual course: dialogues, basic sentences, sentence-pattern drills. In response to my recent request for information, the CeLt advised me, "Our old card catalog lists those materials simply as “Intensive Indonesian Program” by Harsono & Baird, 1965." I have been trying to locate a copy of the accompanying textbook but my efforts have not yet met with success. I have sent a request to the Indiana University's Southeast Asia Studies department asking them if they might have a copy of the textbook. If I receive a reply, I will advise further. UPDATE: The Librarian for South Asian and Southeast Asian Studies, Indiana University, kindly replied to my enquiry advising me that they have no record of the afore-mentioned textbook. This is a real shame, as the audio recordings, which are about 15 hours in length, are of a very high quality. Sigh, perhaps a fellow member will offer to transcribe them, along with an English translation, for posting on the FSI-Languages-Courses database ... sigh.
An audio-lingual course in Bahasa Indonesia / H. Hendrata
Under the separate discussion thread "Audio lingual language programs", PeterBeischmidt made mention of this course as follows: "I found an entry for what appears to be another audio-lingual course for Indonesian:
Code: Select all
Titel: An audio-lingual course in Bahasa Indonesia / H. Hendrata
Sonst. Personen: Hendrata, Hendy
Ort/Jahr: Carlton : Hendrata, 
They also seem to have the tapes, unless they've thrown them away without updating the catalogue."
University of Michigan LRC
Recently, the University of Michigan LRC ceased selling the archived audio recordings that were created some years ago to accompany textbooks, often published by the UofM, for a number of the less-commonly-studied languages. Many of these textbooks used the audio-lingual method of instruction or a modified version of it. In lieu of selling the archived audio recordings, the UofM now offers them free-of-charge as MP3 downloads, in response to specific requests. Since the university offers a course in Indonesian, it is possible that free-of-charge downloadable recordings exist. Requests should be directed to: [url]http://www.ls[url][/url]a.umich.edu/lrc/sales[/url]. Should anyone receive the LINK to such files, I am sure that other forum members would appreciate it being posted here under this discussion thread.
Bahasa Indonesia: Introduction to Indonesian Language and Culture, Books 1 & 2, Yohanni Johns
The Amazon customer reviews of the two-volume set "Bahasa Indonesia" by Yohanni Johns are quite positive: http://www.amazon.com/Bahasa-Indonesia-Book-Introduction-Indonesian/dp/0945971567/ref=sr_1_11?ie=UTF8&qid=1452199153&sr=8-11&keywords=learn+indonesian. Unfortunately, I have been unable to locate audio recordings for this course.
