Abstract

Abstrak---Logika  crisp merupakan  sistem  logika yang hanya mempunyai  dua nilai  keanggotaan benar atau salah. Dalam  implementasinya,  terdapat  hal-hal yang tidak tepat bila direpresentasikan  hanya secara  benar  dan  salah. Karena itu, digunakanlah  sistem  logika fuzzy dimana terdapat  nilai-nilai diantara benar  dan  salah. Konsep  ini banyak diaplikasitan  terutama  untuk sistem  kontrol, salah  satunya  pada  traffic light. Sistem  pengaturan traffic light dengan konsep  logika  fuzzy mampu  bekerja  sesuai  kondisi  jalan yang diaturnya.  Sistem  inferensi  fuzzy menggunatan  metodi Min-max. Input crisp diubah menjadi input  fuzzy, kemudian  dievaluasi  dengan basis  pengetahuan  menggunakan  kaidah-kaidah  fuzzy  yang akhirnya  dihasilkan sebuah solusi daerah fuzzy. Daerah solusi ini selanjutnya dilakukan defuzzisasi untuk mendapatkan  sebuah solusi  crisp  sebagai  dasar penentuan  durasi lampu hijau pada traffic light.Kata  kunci  : Logika fuzzi, sistem inferensi fuzzy, metode  min-maxPermalink : http://ejournal.undip.ac.id/index.php/sm/article/view/3117

Abstract

Golay codes can be constructed by lexicographic codes. Lexicographic codes constructed by Greedy algorithm. Greedy construction is one type of Greedy algorithm. Given codes with minimum distance d and length n. To construct the greedy algorithm, the codeword with length n are processed in some fixed order, and the next codeword is inserted in the code when its distance from all codewords previously selected is  d. On Greedy construction, to set (n, k,d) codes, we only need to set (n-k,k) codes with  k iteration.   Keywords: linear codes, lexicographic codes, Golay, generator matrix

Abstract

ABSTRACT--At digital message delivery process in the form of code may will experience of trouble in couse of  its transmission so that generate the error of accepted message. Hamming Code (n,k,d) is one of method that coald detect error and correct error that happened at one blow. Coding process  of message by Hamming  Code (n,k,d) can be done by multiply of message word delivered with the generator matrix G. Then for the Coding process of codewords accepted can be done with method of vector error, the method started by determined the syndrome, and continued with the error detrection process and also error correetion process. The final step is read the codeword by multiply  codeword accepted with parity check matrix H toget the message such as those which transmissionfrom the beginning. Keyword:  Hamming Code (n,k,d), generator matrix, the parity check matrix, syndrome, error correcting code
