Abstract
ABSTRAK Penelitian ini bertujuan untuk mengetahui pengaruh daya (watt) lampu neon terhadap pertumbuhan tanaman Pak Choi pada sistem hidroponik indoor. Penelitian ini dilakukan dengan menggunakan beberapa pot tanaman Pak Choi di bawah perlakuan pencahayaan yang berbeda. Perlakuannya terdiri dari lampu neon 20 watt (N1), neon 2 x 20 watt (N2), neon 40 watt (3), neon 2 x 40 watt (N4) di ruang tanam dan 1 perlakuan di bawah penyinaran matahari (N0). Hasil penelitian yang diperoleh menunjukkan bahwa perlakuan lampu neon 2 x 40 watt (N4) memberikan hasil terbaik pada semua variable pengukuran. Kemudian diikuti perlakuan neon 40 watt (N3) dan terendah pada perlakuan neon 20 watt (N1). Berat berangkasan tertinggi pada N4 sebesar 35 g, diikuti N3 sebesar 18 g, dan kemudian N2 sebesar 15 g dan N1 sebesar 4 g. Namun, kadar abu tertinggi pada perlakuan lampu neon 20 watt (N1), dan diikuti perlakuan N2 (neon 2 x 20 watt). Meskipun tanaman Pak Choi di bawah perlakuan sinar matahari memiliki berat berangkasan tertinggi, tetapi memiliki kandungan mineral terendah. Kata kunci : Lampu neon, daya lampu, Pak Choi, hidroponik sistem sumbu ABSTRACT The purpose of this research was to observe the influence of neon lamp power (watt) on the growth of Pak Choi in an indoor hydroponic system. This research was done by implementing several pots of Pak Choi planting under some different treatments of lighting. The treatment consisted of neon lamp 20 watt (N1), neon 2 x 20 watt (N2), neon 40 watt (N3), neon 2 x 40 watt (N4) in a growth chamber and one treatment under the sun lighting (N0). The result of the research showed that the treatment of 2 x 40 watt neon lamp (N4) turned out to have the best result at all variables measured. Then, it was followed by treatment of neon 40 watt (N3) and the lowest result was in neon 20 watt (N1). The highest biomass harvested was 35 g in N4, followed by 18 g in N3, then the 15 g in N2 and 4 g in N1. However, the highest ash content was in the treatment of 20 watt neon lamp (N1), and followed by N2 (neon 2 x 20 watt). Although, Pak Choi grown under the sun ray has the highest biomass harvested, but it had the lowest mineral content. Keywords : Neon lamp, lamp power, Pak Choi, hydroponic wick system
