Penelitian Ini Bertujuan Untuk Mengetahui Pengaruh Komposisi Media Tanam Dan Perlakuan Komposisi Media Tanam Yang Terbaik Terhadap Produksi Tanaman Tomat Dengan Sistem Fertigasi. Perlakuan Disusun Dengan Rancangan Acak Kelompok (RAK) Faktor Tunggal Yaitu Perlakuan Komposisi Media Tanam Yang Terdiri Dari 10 Taraf Perlakuan Yaitu: Pasir (M1), Arang Sekam (M2), Serbuk Gergaji (M3), 1/3 Pasir + 1/3 Arang Sekam + 1/3 Serbuk Gergaji (M4), 2/3 Pasir + 1/3 Arang Sekam + 0 Serbuk Gergaji (M5), 2/3 Pasir + 0 Arang Sekam + 1/3 Serbuk Gergaji (M6), 1/3 Pasir + 2/3 Arang Sekam + 0 Serbuk Gergaji (M7), 0 Pasir + 2/3 Arang Sekam + 1/3 Serbuk Gergaji (M8), 1/3 Pasir + 0 Arang Sekam + 2/3 Serbuk Gergaji (M9), 0 Pasir + 1/3 Arang Sekam + 2/3 Serbuk Gergaji (M10). Ulangan Sebanyak 4 Kali. Hasil Penelitian Menunjukkan Bahwa Perlakuan Komposisi Media Tanam M7 Memberikan Pengaruh Nyata Terhadap Jumlah Buah Per Tanaman, Diameter Buah, Total Bobot Buah, Dan Indeks Panen. Perlakuan Komposisi Media Tanam M7 Memberikan Pengaruh Terbaik Dibandingkan Perlakuan Media Lainnya.
Kata kunci: komposisi media, pasir, arang sekam, serbuk gergaji, Lycopersicon esculentum Mill.

This Study Aims To Determine The Effect Of Planting Media Composition And Treatment Of The Composition Of The Best Growing Media To The Production Of Tomato Plants With Hydroponics Fertigation System. The Treatments Are Arranged With A Randomized Complete Block Design (RCBD), Single Factor, That Treatment Plant Media Compositions Comprising 10 Standard Of Treatment That: Sand (M1), Husk Char (M2), Sawdust (M3), Sand 1/3 + Husk Char 1/3 + Sawdust 1/3 (M4), Sand 2/3 + Husk Char 1/3 + 0 Sawdust (M5), Sand 2/3 + Husk Char 0 + Sawdust 1/3 (M6), Sand 1/3 + Husk Char 2/3 + Sawdust 0 (M7), 0 Sand +2/3 Husk Char + Sawdust 1/3 (M8), Sand 1/3 + Husk Char 0 + Sawdust 2/3 (M9), Sand 0 + 1/3 Husk Char + Sawdust 2/3 (M10). With 4 Replication. The Results Showed That The Treatment Plant Media Composition M7 Significant On The Number Of Fruit, Fruit Diameter, The Total Weight Of The Fruit, And Harvest Index. Treatment Of Growing Media Composition M7 Gives The Best Effect Of Treatment Than Other Media. Keywords: media composition, sand, husk char, sawdust, Lycopersicon esculentum Mill.
