Pada sistem tersebut, metode tanam hidroponik dapat dilakukan di dalam ruangan. Tanaman hidroponik tetap membutuhkan sumber cahaya untuk melakukan proses fotosintesis. Hanya sedikit dari energi cahaya yang dipancarkan yang digunakan tanaman untuk fotosintesis karena gelombang cahaya yang ditangkap setiap tanaman berbeda satu dengan yang lainnya tergantung dari jenis tanaman. Oleh karena itu, perlu dibuat aplikasi alat pengaturan cahaya untuk tanaman hidroponik sehingga bisa mendapatkan hasil yang optimal. Dengan adanya alat yang dapat mengatur cahaya menggunakan perangkat Android dan Arduino yang terkoneksi melalui bluetooth, penyesuaian warna dan intensitas cahaya yang dibutuhkan tanaman pada metode tanam hidroponik dapat membantu mencapai hasil yang optimal.

I. PENDAHULUAN

A. Latar Belakang Hidroponik merupakan suatu sistem pertanian masa depan karena dapat diusahakan di berbagai tempat[1]. Sedikitnya lahan pertanian, keterbatasan air untuk irigasi, dan musim yang tidak menentu dapat ditanggulangi dengan sistem hidroponik. Hidroponik dapat diusahakan sepanjang tahun tanpa mengenal musim. Pemeliharaan tanaman hidroponik pun lebih mudah karena tempat budidaya relatif bersih, media tanam yang steril, tanaman terlindungi dari terpaan hujan, serangan hama dan penyakit relatif lebih kecil, serta tanaman lebih sehat dan produktivitas lebih tinggi[2]. Kelebihan lain metode menanam hidroponik adalah perawatan yang praktis, pemakaian pupuk lebih hemat, tanaman yang mati lebih mudah diganti dengan tanaman yang baru, kerja lebih hemat dan memiliki standar[3]. Pada tanaman, diketahui bahwa energi sinar yang digunakan tumbuhan untuk fotosintesis hanya 0,5-2% dari jumlah energi yang tersedia. Energi yang diberikan itu tergantung kepada kualitas (panjang gelombang), intensitas (banyaknya sinar per 1 cm2 per detik) dan waktu[4]. Setiap tanaman menyerap cahaya yang berbeda-beda tergantung dari membran grana yang terdapat pada tumbuhan. Hasil tanaman yang baik diperoleh melalui perlakuan yang tepat pada tanaman. Salah satu perlakuan bagi tumbuhan yaitu dengan pengaturan intensitas cahaya yang didapat karena berhubungan erat dengan aktivitas fotosintesis tanaman[5]. Pengaturan cahaya pada tanaman hidroponik dapat dilakukan dengan mengubah-ubah intensitas dan warna cahaya yang digunakan sehingga cahaya yang didapat tanaman akan sesuai dengan panjang gelombang yang dapat diterima tanaman. Pengaturan cahaya secara otomatis dapat dilakukan menggunakan perangkat Arduino. Arduino merupakan suatu papan elektronik yang mengandung mikrokontoller di dalamnya dan dapat diprogram menggunakan bahasa

Processing[6]. Perangkat Arduino merupakan perangkat keras open source, perangkat keras open source dapat dikembangkan dengan penambahan komponen dan secara umum pengembangnya akan berbeda di seluruh dunia. Serta software Arduino dapat diunduh, dipakai, dikembangkan, diubah, bahkan dijual kembali[7]. Jenis Arduino yang digunakan adalah Arduino Mega 2560, perangkat ini memiliki 54 pin input/output yang mana 15 pin digunakan sebagai PWM keluaran, 16 masukan analog, 16 MHz osilator kristal, USB koneksi, power, ICSP, dan tombol reset[8]. Perangkat ini pun dapat berintegrasi dengan perangkat Android. Perangkat Android memiliki banyak kelebihan dibandingkan dengan sistem operasi sejenis. Selain home screen yang fleksibel, aplikasi yang dapat bekerja secara bersamaan (multi tasking), sistem operasi Android juga dapat dimodifikasi oleh pengguna[9]. Pada sisi pengembangan Android, kelebihan terdapat pada mudahnya pembuatan Aplikasi pada sistem operasi Android karena menggunakan bahasa tinggat tinggi Java, dan pengembangan layout menggunakan Extensible Markup Language (XML)[10]. Kondisi lahan pertanian yang semakin sempit di Indonesia, serta musim yang tidak menentu menjadikan metode hidroponik dapat menjadi solusi bagi pertanian Indonesia. Dengan ditambahkan pengaturan otomatis menggunakan perangkat Arduino dan Android dapat mempermudah dalam bercocok tanam metode hidroponik. B. Rumusan Masalah Persoalan yang dibahas adalah cara pengaturan cahaya menggunakan perangkat Android dengan bluetooth sebagai media untuk komunikasi. Hal ini untuk mempermudah pengaturan cahaya pada metode tanam hidroponik. Sehingga cahaya yang digunakan untuk menanam hidroponik dapat diatur dan diketahui kondisinya. Sistem hidroponik dapat menjadi solusi bagi pertanian Indonesia karena dapat dilakukan di lahan yang sempit serta tanaman lebih aman dari serangan hama dan penyakit. Sehingga metode tanam

hidroponik dengan pengaturan otomatis menggunakan aplikasi Android dapat memudahkan petani dalam mengatur cahaya sehingga mendapatkan hasil yang maksimal. C. Tujuan Penelitian Tujuan dari penelitian ini adalah terciptanya alat pengaturan cahaya untuk metode tanam hidroponik menggunakan perangkat Android dan Arduino sehingga penggunaan alat ini dapat meningkatkan hasil pertanian.

II. RANCANGAN ALAT

A. Diagram Blok

Urutan penggunaan alat yang akan dibuat adalah user masuk kedalam aplikasi lalu memilih mode pengaturan LED (Light Emitting Diode) menggunakan broadcast atau unit control. Setelah itu perintah akan dikirimkan melalui bluetooth yang terdapat pada ponsel kemudian akan diterima oleh bluetooth module yang tedapat pada Arduino. Sehingga Arduino akan mengirim perintah kepada LED RGB (Red Green Blue) sesuai dengan perintah yang dikirimkan oleh user. Data-data yang terdapat pada Arduino dikirimkan ke aplikasi Android agar user dapat melihat status pada LED. Terdapat juga pengaturan waktu (Timer) untuk mengatur pencahayaan pada waktu tertentu secara otomatis sehingga user tidak perlu merubah warna cahaya pada setiap waktu.

B. Desain Alat Pada alat ini terdapat 3 buah LED RGB untuk mengatur cahaya pada tanaman hidroponik. Setiap tanaman terdapat sekat untuk memisahkan antar tanaman agar saat pengaturan cahaya yang berbeda (unit control) pada LED tidak mempengaruhi pencahayaan pada bagian yang lain. Metode tanam pada gambar adalah metode tanam sistem wick (sumbu) karena metode hidroponik jenis ini paling mudah untuk diaplikasikan dan paling baik untuk tanaman tunggal[11].

IV. ANALISIS

Pada uji coba pertama adalah melakukan tes aplikasi, yaitu buka dan tutup aplikasi, dan komunikasi bluetooth dari aplikasi Android terhadap modul Arduino. Pada uji coba komunikasi bluetooth, dilakukan beberapa tahapan uji coba yaitu ketika terdapat perangkat dan tidak ada perangkat, lalu pairing perangkat, penerimaan data status dari Arduino, dan memutuskan pairing perangkat. Untuk penerimaan data status ini nantinya akan diketahui kondisi pada sistem dan dapat ditampilkan pada aplikasi Android. Setelah uji coba komunikasi aplikasi, dilanjutkan dengan uji coba pengaturan LED dengan 2 jenis pengaturan yaitu unit control dan broadcast. Pada uji coba unit control, pengiriman perintah dilakukan satu per satu LED dan mengubah kecerahan pada setiap LED. Kondisi LED mampu berbeda warna satu dengan yang lainnya pada saat yang bersamaan dan kecerahannya juga dapat diatur pada setiap LED. Berbeda dengan unit control, uji coba pada mode broadcast dilakukan pengaturan warna dan kecerahaan saat yang bersamaan dan dapat dikerjakan pada saat yang bersamaan oleh semua LED. Selain itu terdapat fitur timer pada setiap mode, terdapat pada mode unit control dan broadcast. Timer digunakan untuk

mengatur waktu hidup dan mati serta dapat merubah warna LED pada waktu tertentu.

V. KESIMPULAN

Kesimpulan yang didapat adalah aplikasi dimungkinkan untuk dibuat melihat hasil uji coba dengan keberhasilan penuh pada setiap bagian uji coba. Sehingga dengan adanya alat ini dapat memudahkan petani yang menggunakan sistem bercocok tanam hidroponik dalam pengaturan cahaya tanaman.
