Pengaruh Subtitusi Cahaya Matahari dengan Lampu Led Terhadap Pertumbuhan Tanaman Padi (Oryza Sativa) Varietas IR 64

Abstract

Budidaya padi pada ruangan tertutup membutuhkan cahaya artifisial untuk menunjang pertumbuhan dan hasil tanamanan padi. Cahaya yang diberikan terus meliputi beberapa faktor diantaranya intesitas cahaya, lama penyinaran dan kualitas cahaya. Penelitian ini bertujuan untuk mengetahui pengaruh daya lampu LED terhadap pertumbuhan dan hasil tanaman padi sistem budidaya hidroponik rakit apung. Penelitian ini menggunakan RAL (Rangcangan Acak Lengkap) dengan empat perlakuan, yaitu: P0 (kontrol/cahaya matahari), P1 (lampu LED 100 watt), P2 (lampu LED 200 watt) dan P3 (lampu LED 300 watt) yang diulang sebanyak sepuluh kali. Parameter yang diamati meliputi tinggi tanaman, jumlah anakan, bobot berangkasan basah dan bobot berangkasan kering tanaman. Perlakuan dilakukan pada kotak ukuran 60 cm x 40 cm x 30 cm yang ditempatkan pada 2 tempat, di luar ruangan dan di dalam ruangan gelap (indoors). Hasil penelitian menunjukkan bahwa perlakuan kontrol (P0) memberikan hasil terbaik dengan tinggi tanaman (111,11 cm), jumlah anakan (9 batang), bobot berangkasan basah (359,67 g), bobot berangkasan kering (64,74 g)Rice cultivating in a closed room requires artificial light to support the growth and yield of rice plants. The light provided by herus includes several factors including light intensity, length of exposure and light quality. This research aims to determine effect of the power LED lamp on the growth and yield of rice plants in the floating raft hydroponic cultivation system. This research used Randomized block Design with four treatments, namely: P0 (control/sunlight), P1 (LED lamp 100 watt), P2 (LED lamp 200 watt) and P3 (LED lamp 300 watt) which were repeated ten times. The parameters observed included plant height, number of plant saplings, wet stem weight, and dry stem weight. The treatment was carried out in boxes measuring 60 cm x 40 cm x 30 cm which were placed in 2 places, outdoors and in a dark room (indoors). The results showed that the control treatment (P0) gave the best results, with plant height (111.11 cm), number of plants saplungs (9 stems), wet stem weight (359.67 g), dry stem weight (64.74 g)
