LA.1. Prosedur Pengoperasian Alat

Bagian ini menjelaskan tentang bagaimana cara mengoperasikan alat pengukur tingkat kematangan buah yang telah dirancang.Komponen yang diperlukan adalah alat pengukur tingkat kematangan buah dan driver (CP210x_VCP_Windows) untuk alat tersebut.

Pertama, sambungkan listrik PLN pada soket 220VAC. Kemudian, sambungkan alat pengukur tingkat kematangan buah dengan komputer menggunakan kabel USB melalui USB Port.Perhatikan lampu indicator.Jika lampu indicator menyala berarti alat sudah mendapatkan arus listrik.Komputer akan melakukan auto detect terhadap alat tersebut. Kemudian, install driver (CP210x_VCP_Windows) untuk alat pengukur tingkat kematangan buah.

Setelah driver terpasangkan, lepaskan kabel USB dari

komputer.Kemudian, pasang kembali, 3 buah lampu indikator pada alat akan berkedip yang menandakan proses inisialisasi alat.Lalu, pasangkan sensor ultrasonik sesuai dengan simbol “T” dan “R”.

Gambar LA.2. Lampu Indikator dan USB Port

Lakukan koneksi dari program MatLab ke alat dan tunggu lampu indikator “C”yang menandakan alat sudah terhubung dengan program MatLab menyala. Tempelkan probe transduser pada buah dengan posisi berseberangan pada buah. Kemudian tekan tombol“Trigger” yang berada di kananlampu kontol untuk memulai proses pembacaan buah.

Setelah tombol ditekan, lampu “P”akan menyala yang menandakan proses pembacaan tingkat kandungan air dan tekstur buah serta proses Analog to Digital Converter sedang berlangsung. Setelah lampu proses padam, disusul dengan lampu “S” menyala yang menandakan proses pengiriman data hasil pengukuran buah sedang dikirimkan ke program MatLab. Setelah pengiriman data selesai, alat kembali dalam posisi standby dan siap untuk melakukan pengukuran kembali pada buah lainnya.

Untuk melepas alat dari komputer, lakukan disconnect dari program MatLab atau tutup program MatLab terlebih dahulu dan tunggu hingga lampu “C” tidak lagi menyala yang menandakan alat sudah tidak terkoneksi dengan program MatLab. Setelah lampu koneksi padam, maka alat sudah dapat dilepaskan dari komputer dengan mencabut kabel USB dan mencabut soket 220VAC.

LA.2. Prosedur Penggunaan Program MatLab

Bagian ini menjelaskan tentang bagaimana cara menggunakan program MatLab yang telah dirancang. Lakukan install terhadap program stand alone MatLab pada komputer dan kemudian buka program tersebut.

Setelah alat dihubungkan dengan komputer, lakukan pemilihan terhadap port yang menjadi koneksi dari komputer ke alat.Kemudian, tekan tombol connect untuk melakukan koneksi dengan alat. Koneksi berhasil ditandai dengan berubahnya tombol connect menjadi disconnect.

Selanjutnya, melakukan pemilihan terhadap jenis buah yang ingin dilakukan pembacaan tingkat kematangannya.Jenis buah yang dapat dipilih

terdapat pada bagian “Pilih Buah”. Tidak tepatnya pemilihan jenis buah akan mengalami pembacaan tingkat kematangan buah tidak tepat.

Kemudian, menunggu alat memulai proses pembacaan dan mengirimkan datanya ke program MatLab. Ketika data diterima, maka akan ditampilkan pada program MatLab sehingga pengguna dapat melihat tingkat kematangan buah. Jika ingin melakukan pembacaan berikutnya, cukup menunggu saja data dari alat. Tapilan akan dibersihkan dan diganti dengan data pembacaan yang baru.

Ketika selesai menggunakan program, lakukan disconnect terlebih dahulu dan kemudian keluar dari program atau dapat langsung menekan tombol “Exit” atau menggunakan tanda silang yang terdapat pada kanan atas dari tampilan program tanpa melakukan disconnect terlebih dahulu.
