SOA!&PERMASA!AHAN

Menghitung panjang pita, lama akses, dan transfer rate pada magnetic tape dengan inputan

berupa jumlah record, panjang record, IRG, IBG, blocking factor, data dencity, dan laju pita.

Perhitungan dilakaukan dengan metode blocking dan tanpa blocking.

A!GORITMA PROGRAM

1. Program ijalankan

!. Menampilkan home dengan pilihan tanpa block dan blok.

". #ika memilih menu $anpa Block, menampilkan halaman baru berupa inputan data jumlah

record, panjang record, irg, data dencity, dan laju pita.

%. apabila jumlah record kurang dari &'nol(, akan menampilkan toast 'pesan dialog(.apabila

data yang diinputkan ada yang kosong atau kurang dari &'nol(, akan menampilkan toast

'pesan dialog(.

). #ika data *alid maka 'menghitung menggunakan metode tanpa blocking(

Panjang Pita +record - 'panjang 1 recordIRG(

/ama 0kses + Panjang Pita/aju Pita

$ransfer Rate + byte/ama 0kses

2. #ika memilih menu Block, menampilkan halaman baru berupa inputan data jumlah

record, panjang record, ibg, blocking factor, data dencity, dan laju pita.

3. apabila jumlah record kurang dari &'nol( atau blocking factor bernilai kurang dari sama

dengan &'nol(, akan menampilkan toast 'pesan dialog(.apabila data yang diinputkan ada

yang kosong atau kurang dari &'nol(, akan menampilkan toast 'pesan dialog(.

4. #ika data *alid maka 'menghitung menggunakan metode blocking(
