<![CDATA[Dendrobium orchids are a type of epiphytes that are easy to maintain and flower throughout the year. Fertilizer for the growth of orchid plants commonly used is NPK fertilizer or fertilizer with complete elements. Research has been conducted that aims to determine the effect of leri water and fish emulsion on the growth of Dendrobium orchids and to find out how leri water and fish emulsions differ in concentration to the growth of Dendrobium orchids at the vegetative stage. This study used a randomized block design (RBD) using 66% leri water treatment, 100% leri water, 0.4% fish emulsion, 0.6% fish emulsion, 66% leri water plus 0.4% fish emulsion, lime 66% plus fish emulsion 0.6%, 100% leri water plus 0.4% fish emulsion and 100% lyric water plus 0.6% fish emulsion. Observation data were tested by ANOVA and the results showed that 66% of leri water treatment affected plant length. Effect on plant length, leaf length and number of leri leaves added by fish emulsion at all concentrations affecting the leaf length. All treatments except 100% liquid water and fish emulsion and K1 (-) affected the number of leaves Keyword: leri water, fish emulsion, orchid Dendrobium, vegetative stage ABSTRAK Anggrek Dendrobium merupakan jenis epifit yang mudah dipelihara dan berbunga. Pupuk anggrek yang biasa digunakan adalah pupuk NPK atau pupuk dengan unsur lengkap. Penelitian ini bertujuan untuk mengetahui pengaruh air leri dan emulsi ikan terhadap pertumbuhan anggrek Dendrobium dan untuk mengetahui bagaimana air leri dan emulsi ikan dengan berbeda konsentrasi terhadap pertumbuhan anggrek Dendrobium pada tahap vegetatif. Penelitian ini menggunakan rancangan acak kelompok (RAK) dengan uji ANOVA. Menggunakan perlakuan air leri 66%, air leri 100%, emulsi ikan 0,4%, emulsi ikan 0,6%, air leri 66% ditambah emulsi ikan 0,4%, air leri 66% ditambah emulsi ikan 0,6%, air leri 100% ditambah emulsi ikan 0,4%, air leri 100% ditambah emulsi ikan 0,6%. Hasil penelitian ini adalah perlakuan air leri 66% pada panjang tanaman, air leri 66% ditambah emulsi ikan 0,4% pada panjang daun dan air leri 100% ditambah emulsi ikan 0,4% pada jumlah daun dan panjang akar.
