| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk 1) mengetahui pengaruh warna cahaya terhadap pertumbuhan dan hasil selada, 2) mengetahui pengaruh jarak lampu terhadap pertumbuhan dan hasil selada, 3) mengetahui pengaruh interaksi warna cahaya dan jarak lampu yang optimum untuk pertumbuhan dan hasil tanaman selada. Penelitian telah dilaksanakan di Kelurahan Kradenan RT 06 RW 02, Kecamatan Sumpiuh, Kabupaten Banyumas dengan ketinggian tempat 70 m dpl serta Laboratorium Agronomi dan Hortikultura, Fakultas Pertanian, Universitas Jenderal Soedirman Purwokerto. Penelitian dilaksanakan dari bulan April sampai Mei 2019. Penelitian menggunakan Rancangan Petak Terbagi (Split Plot Design) faktorial. Petak utama adalah warna cahaya yaitu merah, biru dan putih; dan anak petak adalah jarak lampu yaitu 60 cm, 90 cm dan 120 cm; sehingga terdapat 9 perlakuan yang diulang sebanyak 3 kali. Sumber cahaya menggunakan lampu LED dengan total daya sebesar 36 watt setiap unit percobaan. Variabel yang diamati yaitu intensitas cahaya, evapotranspirasi, tinggi tanaman, jumlah daun, luas daun, kehijauan warna daun, bobot tanaman segar, bobot tanaman kering, bobot akar segar, dan bobot akar kering. Data pengamatan dianalisis dengan uji F taraf 5% dan apabila berbeda nyata dilanjutkan dengan uji lanjut Duncan’s Multiple Range Test (DMRT) taraf kesalahan 5%. Hasil penelitian menunjukkan bahwa intensitas cahaya warna biru menunjukkan paling tinggi sebesar 4,88 k lux dan menyebabkan daun selada nampak lebih hijau berdasarkan klorofil meter SPAD (skala warna 4,32). Semakin dekat sumber cahaya (jarak lampu) maka pengaruh cahaya tersebut semakin besar. Pertumbuhan dan hasil tanaman selada paling tinggi pada jarak lampu 60 cm. Intensitas cahaya warna biru dengan jarak lampu 60 cm dari permukaan media tanam sebesar 8,1 k lux, menunjukkan yang paling tinggi dibandingkan perlakuan lainnya. Pertumbuhan tinggi tanaman dan jumlah daun tertinggi pada warna cahaya merah dengan jarak lampu 60 cm, tetapi pertumbuhannya menurun menjadi paling rendah pada jarak lampu 120 cm. |

| Abtrak (Bhs. Inggris) | This research aims to 1) determine the effect of light color on lettuce growth and yield, 2) find out the effect of lamp distance on lettuce growth and yield, 3) find out the effect of the interaction of light color and optimum lamp distance for growth and yield of lettuce plants. Research has been carried out in Kradenan Sub-District RT 06 RW 02, Sumpiuh Subdistrict, Banyumas Regency with a place height of 70 m above sea level as well as the Agronomy and Horticulture Laboratory, Faculty of Agriculture, Jenderal Sudirman University Purwokerto. The study used factorial Split Plot Design. The main plot is the color of light, red, blue and white; and subplot is the distance of the lights namely 60 cm, 90 cm and 120 cm; so that there are 9 treatments that were repeated 3 times. The light source uses an LED lamp with a total power of 36 watts per unit of an experiment. The variables observed were light intensity, evapotranspiration, plant height, leaf number, leaf area, leaf color greenness, fresh plant weight, dry plant weight, fresh root weight, and dry root weight. Observation data were analyzed with an F test of 5% level and if it was significantly different, it was continued with Duncan's multiple range test (DMRT) with an error level of 5%. The results showed that the light intensity of blue showed the highest of 4.88 k lux and caused the lettuce leaves to appear greener based on chlorophyll meter SPAD (color scale 4.32). The closer the light source (the distance of the lamp) the greater the effect of the light. The highest growth and yield of lettuce at a distance of 60 cm. The intensity of the blue light with a distance of 60 cm from the surface of the planting medium was 8.1 k lux, indicating the highest compared to other treatments. The highest growth in plant height and number of leaves in a red light color with a distance of 60 cm light, but its growth decreased to the lowest at 120 cm lamp distance. |
