TEORI BAHASA AUTOMATA

Assalamu'alaikum Wr.Wb.

Hallo apa kabar? Semoga sehat selalu yaa. Akhirnya kita berjumpa lagi 😁. Untuk postingan kali ini , saya akan memposting sebuah Teori Bahasa Automata yaitu Membuat Mesin Deterministic Finite Automata (DFA),  Non-deterministic Finite Automata (NFA) dan Pushdown Finite Automata (PDFA)
. Pasti sudah ada yang tahu kan? dan mungkin sudah pernah membuat, langsung saja ya berikut penjelasan tentang Materi di atas :

 A. Deterministic Finite Automata (DFA)
DFA (Deterministic Finite Automata) adalah FSA(finite state automata) yang memiliki stata penerima tepat satu stata untuk setiap simbol masukan.

Contoh Kasus

Formal penulisan :

M = (Q, ∑, δ, S, F),
Q = {q0, q1, q2, q3}
∑ = {0,1}
S = q0
F = {q3}
δ  = 
δ
0

Q0

Hasil Uji Input :



Penjabaran Uji Input sebagai berikut :


Input 1011 à Accept


Input 1001 à Reject


Input 01110 à Accept



B. Non-deterministic Finite Automata (NFA)

-          Suatu string diterima oleh DFA bila terdapat suatu urutan transisi sehubungan dengan input string tersebut dari state awal sampai state akhir.
-          NFA harus dicoba semua kemungkinan yang ada sampai terdapat satu yang mencapai state akhir.
-          Suatu string x dinyatakan diterima oleh bahasa NFA, M = (Q, ∑, δ, S, F)
-          Bila {x | δ(S,x) memuat sebuah state di dalam F}

      Contoh Kasus :
      
      
Formal penulisan :

M = (Q, ∑, δ, S, F),

Q = {q0, q1, q2, q3}

∑ = {0,1}

S = q0

F = {q2}

 δ  = 

δ

Hasil Uji Input :


Penjabaran Uji Input sebagai berikut :
Input 1010 à Reject
Trace


Input 1100 à Reject
Trace


Input 1101 à Reject
Trace


C. Pushdown Finite Automata (PDFA)
PDA adalah mesin otomata yang memiliki kendali masukan menggunakan teknik LIFO (Last In First Out), untuk menentukan apakah suatu output diterima atau tidak oleh mesin tsb. Dalam melakukan proses peneerimaan input, PDA menggunakan memory stack.

Contoh Kasus


Formal penulisan :
Q = {q0, q1, q2}
Σ = {a, b}
Γ = {b, Z}
δ = {(q0, b, b, q0, bb), (q0, b, Z, q0, bZ), (q1, a, b, q1, λ), (q1, λ, Z, q2, Z)}
qs= q0
F = {q2}
Z 

Hasil Uji Input :


Input bbbbaa à Reject
Trace


Input bbbaa à Reject
Trace


Input bbbbaaaa à Accept
Trace


Sekian penjelasan mengenai DFA, NFA, dan PDFA apabila ada kurangnya saya mohon maaf. 

Terimakasih dan semoga bermanfaat untuk semuanya. 

Wassalamu'alaikum Wr. Wb.

PROGRAM UAS "PERPUSTAKAAN"

Assalamualaikum Wr. Wb.

Hai teman-teman, apa kabar? semoga sehat selalu ya,. Pada postingan ke dua dari Blog saya ini, saya akan menjelaskan tentang Program Algoritma yang saya buat, masih mengenai Program Perpustakaan Buku. Namun untuk postingan kedua ini terdapat beberapa komponen yang saya tambahkan. Untuk lebih jelasnya langsung saja lihat pada penjelasan dibawah ini, yaaa.. :-)


Program Perpustakaan ini bertujuan untuk membantu Petugas Perpustakaan dalam kaitannya dengan Pendataan dan Peminjaman Buku Perpustakaan yang dipinjam , agar lebih mudah , efisien , serta menghemat waktu .
Ada beberapa Form pada Program tersebut diantaranya Form Login, Form Menu Utama, Form Data Buku dan Form Peminjaman Buku. Berikut penjelasan detailnya..


1. Flowchart

2. Form Login
  • digunakan untuk Login Petugas Perpustakaan, berikut tampilan desainnya.



  • Isikan data petugas sebagai awal Pengoperasian Program, lalu klik Button Login seperti berikut:


  • Setelah sukses Login maka akan terhubung ke Form Menu Utama.
2. Form Menu Utama

          Pada Menu Utama dibawah ini, terdapat 2 Form, yaitu Data Buku dan Peminjaman Buku.


3. Form Data Buku.



Pada Form Data Buku diatas berisi Data-Data Buku yang ada pada Perpustakaan, kita dapat menambah, mengupdate, menghapus dan menampilkan Laporan mengenai Data tersebut.

a. Pertama , Menambah Data Buku Baru , isikan data pada Form tersebut, lalu klik Save, akan muncul kotak dialog Berhasil , klik Oke.


           Setelah Klik Oke maka akan muncul Data Buku Baru yang diisikan, pada Tabel tersebut.


b. Kedua, Mengupdate Data Buku, apabila ada kesalahan saat memasukkan Data sebelumnya.
Klik pada tabel , data mana yang akan di update, setelah muncul pada TextField , ganti Data yang akan di update misal Tahun, setelah itu Klik Button Update.


setelah muncul tampilan seperti diatas Klik Oke, maka Tahun Buku yang terdapat pada Tabel akan berubah , berikut tampilannya


c. Ketiga, Menghapus Data, klik pada tabel, data mana yang akan dihapus, lalu klik Button Delete, akan muncul Konfirmasi       "Apakah Anda yakin akan menghapus data?" jika iya klik Oke , setelah klik Oke akan muncul kotak dialog lagi yang bersii informasi bahwa "Data telah berhasil di hapus", klik Oke.





d. Keempat, Menampilkan Report / Laporan Data Buku, klik Report akan muncul tampilan sebagai berikut



4. Form Peminjaman Buku
untuk mendata Peminjam dan Buku yang di pinjam, serta Sewa Buku tersebut, dihitung dari Lama Pinjam dikali (x) harga sewa.

a. Tampilan Desain 



b. Isikan data yang dibutuhkan 


c. Klik Proses



d. Klik Simpan, untuk menyimpan data pada Database, jika berhasil pilih Oke.


e. Untuk menampilkan Laporan Klik Report



f. Jika sudah selesai dan ingin Keluar/Exit Pilih Button Exit , lalu Klik Yes


Tampilan Struktur Database Perpustakaan Buku menggunakan MySQL

a. Tabel Buku



b. Tabel Peminjam Buku




Source Code pada Form Data Buku :
