RESPON BAYAM BRAZIL (Alternanthera sissoo) PADA APLIKASI SUMBER CAHAYA BUATAN DENGAN MEDIA PUPUK KANDANG KAMBING DAN KOMPOS Eichhornia crassipes

The study aimed to determine the response of Brazilian spinach plants to the application of water hyacinth (Eichhornia crassipes) compost and goat manure with LED and fluorescent artificial light. The research was conducted at KP2 Instiper in Maguwoharjo, Depok, Sleman from April to June 2022. The research used an experimental method with a split-plot design. The main plot in the form of artificial light consists of 3 types, namely: Control (sunlight), 18 Watt Neon Lights, and 36 Watt LED Lights. The subplots consisted of 3 types of organic fertilizers, namely: Control (without fertilizer), water hyacinth compost, and goat manure compost, so 3 x 3 = 9 treatment combinations were obtained, each with 3 replications. Based on the results of the research conducted, it can be concluded that the combination of various light sources and various organic fertilizers affects the growth of Brazilian spinach (Alternanthera sissoo). The growth and biomass of Brazilian spinach in a combination of sunlight and 36 Watt LED lights with water hyacinth compost and goat manure was better than the growth and biomass of Brazilian spinach in a combination of 18 Watt fluorescent lights with various kinds of organic fertilizers. There is a positive correlation between the crown and root biomass. Sunlight and LED have a light intensity that is more suitable for the growth of Brazilian spinach compared to fluorescent lamps.Penelitian bertujuan untuk mengetahui respon tanaman bayam brazil pada aplikasi kompos eceng gondok (Eichhornia crassipes) dan pupuk kandang kambing dengan cahaya buatan LED dan neon. Penelitian dilaksanakan di KP2 Instiper di Maguwoharjo, Depok, Sleman  pada bulan April sanpai Juni 2022. Penelitian menggunakan metode perobaan dengan rancangan split-plot. Mainplot berupa cahaya buatan terdiri dari tiga macam yaitu: Kontrol (cahaya matahari), Lampu Neon 18 Watt dan Lampu LED 36 Watt.  Subplot berupa macam pupuk organik terdiri dari tiga macam yaitu: Kontrol (tanpa pupuk), kompos eceng gondok, dan kompos kotoran kambing, sehingga diperoleh 3 x 3 = 9 kombinasi perlakuan masing-masing dengan 3 ulangan. Berdasarkan hasil dari penelitian yang dilakukan dapat disimpulkan bahwa bahwa kombinasi aplikasi berbagai sumber cahaya dan berbagai macam pupuk organik mempengaruhi pertumbuhan tanaman bayam brazil (Alternanthera sissoo). Pertumbuhan dan biomassa bayam brazil pada kombinasi cahaya matahari maupun lampu LED 36 Watt dengan kompos eceng gondok maupun pupuk kandang kambing lebih baik dibandingkan dengan pertumbuhan dan biomasssa bayam brazil pada kombinasi lampu neon 18 Watt dengan berbagai macam pupuk organik.  Ada korelasi positif antara biomassa tajuk dan biomassa akar. Cahaya matahari dan LED mempunyai intensitas cahaya yang lebih sesuai untuk pertumbuhan bayam brazil dibandingkan dengan lampu neo
