Penelitian ini untuk mengetahui pengaruh pemberian biochar tongkol jagung dan pupuk kandang kambing pada tanaman tapak dara (Catharanthus roseus (L.) G. Don) dan mendapatkan perlakuan terbaik untuk pertumbuhan tanaman tapak dara (Catharanthus roseus (L.) G.Don) telah dilaksanakan pada 28 Januri 2016 hingga 9 Mei 2016 di Desa Sanggra Agung, Kec. Socah, Madura.Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) non faktorial dengan 6 perlakuan 4 ulangan. Perlakuan I yaitu media tanah mediteran (R1), perlakuan II yaitu media tanah mediteran dengan pupuk kandang kambing 50 gram/tanaman (R2), perlakuan III yaitu media tanah kombinasi dengan biochar 1% (R3), perlakuan IV yaitu media tanah dengan biochar 3% (IV), perlakuan V yaitu media tanah kombinasi dengan pupuk kandang kambing 50 gram/ tanaman dengan biocahr 1 % (R5), perlakuan VI yaitu media tanah kombinasi dengan pupuk kandang kambing 50 gram/ tanaman dengan biochar 3 % (R6). Hasil penelitian menunjukkan bahwa perlakuan R4 berpengaruh nyata terhadap parameter tinggi tanaman yang memiliki rerata tertinggi yaitu 54 cm, rerata jumlah daun tertinggi juga yaitu 35 buah, rerata luas daun dengan 845, 9 cm2, rerata jumlah akar yaitu 75 buah, dan bobot kering tanaman tapak dara (Catharanthus roseus (L.) G. Don ) dengan 4,1 gram, namun berpengaruh tidak nyata terhadap akar terpanjang tanaman tapak dara. Kata kunci : biochar, pupuk kandang kambing, tanaman tapak dara

This research was to determine the effect of biochar corncobs and goat manure at the plant of red vinca (Catharanthus roseus (L.) G. Don) and get the best treatment for growing plants of red vinca (Catharanthus roseus (L.) G.Don) has been implemented reviewed Janury 28, 2016 to May 9, 2016 in the village of Sanggra Agung, district. Socah, Madura. This research using completely randomized design (CRD) non factorial with 6 treatment 4 replicates. Treatment of I that the soil media mediterranean (R1), treatment of II on the soil media mediterranean with manure goat 50 grams / plant (R2), treatment III, the soil media in combination with biochar 1% (R3), treatment IV is medium soil with biochar 3 % (IV), V is the media treatment combinations soil with manure goat 50 grams / plant with biocahr 1% (R5), treatment of VI namely soil medium combination with goat manure 50 grams / plant with biochar 3% (R6). The results showed that the treatment R4 significantly affected height parameters of plants that have the highest rates that is 54 cm, the highest also are 35 pieces, average leaf area by 845, 9 cm2, the average number of roots is 75 pieces, and the dry weight of the plant plants of red vinca (Catharanthus roseus (L.) G. Don) with 4.1 grams, but the effect was not significant to longest roots of the plants of red vinca. Keywords: biochar, goat manure, plant vinca
