Bahasa Indonesia is the unity language of Indonesian nation as implied in the Youth Pledge of October 28th, 1928, the language of the country as mentioned in the 1945 Constitution, article 36 which, from the point of language structure, is the variety of Malay language or as it was stipulated in the Indonesian II Congress of 1954 in Medan, The Basics of Indonesia is a Speeding Language adapted to the growth of the Indonesian society ". Chaer  reveals in its development, Indonesian language absorb many elements of regional languages and elements of foreign languages.
One of the development of Indonesian languages comes from elements of regional languages that have enriched the Indonesian language in perkembanggnnya, especially in terms of his vocabulary. Not a few local languages are picked up and then become an Indonesian word , then the number of Indonesian vocabulary increasing one of which comes from the Minangkabau language. The Indonesian vocabulary (BI) is not only accepting the richness of the local languages, but now there should be a vocabulary of local language sources that could potentially be developed as Indonesian riches. It can be proved that in the Big Indonesian Dictionary (KBBI) the existence of Minangkabau (BM) language vocabulary is largely absorption element of indonesian. Based on the writer's observation, the amount of absorption element of BM in BI contained in Huge Indonesian Dictionary Second Edition  amounted to 455 vocabulary.
The research of absorption element of BM in BI by the author's knowledge has never been done. This study examines the formation of Minangkabau language absorption elements in Indonesian language. In this study the authors observed the process of formation of absorption elements of BM in BI.
2. Methodology and Theory
According to Chaer  word absorption is a word that comes from a foreign language or regional language, then used in the Indonesian language. Furthermore, Chaer states that from tarap absorption there are three kinds of absorption words, namely (1) words that have been fully absorbed into the Indonesian language, so it is no longer felt its presence as an absorption word, for example, soursop, advertisement, body. (2) Words that are still foreign, but used in the Indonesian context. Spelling and pronunciation still follow the alien way, for example cock, time out, check in, door to door. (3) Foreign words which for the purposes of terminology, speech and spelling are adapted to Indonesian rules. In this case the change of spelling is made as necessary so that its Indonesian form can still be compared with the original form of the language, such as battery (accu), commission (commission), and phase (phase).
The formation of the absorption element of BM in BI used Chaer approach  about sound changes as a result of morphological process called morphophonemic or morphophonology. In this process it may occur the events of (a) the appearance of phonemes, (b) phonemic releasing, (c) phoneme delivery, (d) phoneme shifts, and (e) phoneme changes. (f) phoneme perpetual. Furthermore, to understand the syllable  is the smallest rhythmic unit in a speech current. A syllable usually involves one vowel sound or one vowel and one or more consonants. The sequence of consonant-vowel sounds in a syllable is called phonotactic. The consonant sound before the vowel (which is the peak of its loudness) is called the onset (O) and the consonant present after the vowel is called the koda (K) while the vowel itself is called the nuklus (N), for example the Indonesian word eating (makan) the syllable is ma-kan but for the word food,the syllable is ma-ka-nan. The sound / n / which becomes the koda (K) in the syllable in the word kan is replaced to an onset (O) on the syllable of nan from the word food. Orthographically, the Indonesian spelling provisions is ma-kan-an, but orthographically labeled ma-ka-nan.
The method used is descriptive method. Source of data obtained from Minangkabau-Indonesia Dictionary Language  and Kamus Besar Bahasa Indonesia (Second Edition) . The method of data provision is done by referring method , for example listening to BM vocabulary in BM dictionary and BI dictionary then use the technique of record, the data collected done recording on the data card which immediately followed by the classification data. The method of data analysis is used by the method of agih tool is precisely part of the language in question  and data analysis technique used technique of lesap, change technique.
3. Results and Discussions
The appearing and changing of phoneme BMBI
The appearance of the phoneme of the absorption element of BM in BI (BMBI) occurs because of the presence of a phoneme which was not present because of the morphological process arises a phoneme in the morphophonemic at the beginning, middle, and end of the word in the following data:
1. andam - handam
In the formation of the Indonesian word absorption element andam into handam (BI) 'memingit'(stay at home) only one data encountered its appearance at the beginning of the word data (1) there is no previous morphophonemic process appear consonant fricative glottal / h / as onset (O) if its basic form starting with the vowel / a / in the first syllable an of the word andam becomes han from word handam. Furthermore, BMBI phonemes appear in the middle of the word in the following data:
2. botok - bontak
3. saok - sahap
The absorption element of BMBI data (2) botok becomes bontak 'round bulb' it appear bo to bon on the first syllable consonant / n / as the koda emerges when the basic form begins with consonant / b / botok becomes bontak as well as vocal changes / o / on the second syllable becomes the vowel / a / followed by the consonant / k /. Data (3) soak if the basic form begins with the consonant / s / becomes a sahap 'cover' phenomenon occurs the appearance of consonant / h / as onset in the second syllable if the second syllable begins with vowel / o / becomes consonant / h / accompanied by vowel / o / being vowel / a / and consonant / k / being consonant / p /. In addition, there are phonemic appearances and changes at the end of the following words:
4. dia - diar 11. jolo - jolor
5. baga - bagar 12. sarawa - serawal
6. dama - damar 13. gawa - gawal
7. kaca - kacar 14. coga - cogah
8. pasa - pasar 15. ungka - ungkah
9. sanga - sangar 16. tungkah - tungkahan
10. ponda - pondar
In the data (4-10) the pattern of consonant appearance /r/ in dia, baga, dama, kaca, pasa, sanga, ponda becomes diar let go, bagar `gulai bagar', damar `candlenut', kacar `grope', pasar `slippery', sangar `stimulating like the smell of union, dan pondar `dumpy' occurs when the second syllable basic word begins with a, ga, ma, ca, sa, nga, and da to be ar, gar, mar, car, sar, ngar, and dar, the appearance of phoneme /r/ in (BI) as koda besides (11) the word jolo becomes jolor `creep' occurs when the second syllable begins with the consonant / l / lo becomes lor, consonant / r / as the code. The data (12) and (13) the sarawa becomes the sarawal 'pants' and gawa become gawal, the consonant / l / as the koda arises when the basic form in the third syllable begins with wa becomes wal while the data 14 and 15 coga becomes cogah 'dashing', and ungka become the ungkah 'dismantle' the appearance of those consonants / h / as koda when the second syllable begins with ga and ka become gah and kah. In addition, the data (16) tungkah becomes tungkahan 'foundation' when the basic word tungkah, second syllable kah ends up with the consonant / h / as the koda gets affixed-an the third syllable where it becomes the onset of the third syllable han on the word tungkahan (BI).
Releasing and changing phoneme BMBI
The absorption of phoneme BM in BI is an event of phoneme loss due to morphological process. The phonemic absorption element of BM in BI is found in the following data:
17. kalikih - keliki
18. sunuah - sunu
In the data (17) there is consonant deletion / h / as the koda on the third syllable kih word kalikih becomes keliki 'papaya fruit'. The data (18) of sunuah into sunu 'burn' occurs consonant deletion / h / as the koda on the second syllable of nuah to nu with the change of diphthong / ua / to be / u /. Both data are imprinted on the second syllable ending with consonant / h /.
Changing phoneme BMBI
The changing phoneme BM in BI (BMBI), that is the changing of a phoneme into another form of phoneme in the following data:
19. kuia - kuir 22. kincia - kincir
20. alia - alir 23. lansia - langsir
21. gabia - gabir
The change of data phonemes (19-23) kuia become kuir 'peasant', alia becomes alir 'slippery', gabia becomes gabir 'unusual', kincia becomes kincir 'jentera', and elderly becomes langsir 'skinny'.

The data is unchanged and the meaning in BI awai `holding', balun 'rolling', cilok 'stealing', dongkak 'crashing', jangkang 'dead', kuyu 'timid', lalah 'chasing', and rasan ` stale' '.
4. Conclusions and Suggestions
Based on the discussion in the process of formation of Minangkabau language absorption element in Indonesian language can be concluded that there are four types of morphophonemic formation, namely the appearance and changes of phonemes, phonemic changes and changes, phoneme changes, and phoneme pengekalan. Based on the pattern (1) the appearance and phoneme changes vary, as the consonant / h / appears at the beginning of the syllable with the vowel / o / vowel / a /; appearance of consonant / n / and / h / in the middle of syllable with vowel change / o / being / a /; and the appearance of the vowel / a / to / ar / at the end of the syllable with the vowel / a / and vowel / e / changes in the first syllable. (2) releasing consonant / h / at the end of syllable accompanied by change of diphthong / ua / into vowel / u /. (3) The final change of syllable is in / ia / becomes / ir /; / ua / being / ur /; / uik / being / ut /; / iak / being / ek / (except); / iah / be / ih /; / uah / being / uh /; / oang / being / ong /; / money / being / ung /; iang being / ing /; / oih / being / as /; / uih / being / us /; / iah / be / ih /; / ih / being / is /. (4) Phoneme consolidation in the absorption element of BMBI does not occur deletion, appearance, or phoneme changes. This research needs to be continued in morphology and syntax studies.
