Daftar Isi:
- ABSTRAK Penelitian bertujuan untuk mengetahui pengaruh serta interaksi antara waktu dekomposisi dan dosis pupuk organik limbah padat virgin coconut oil (VCO) terhadap pertumbuhan kembali dan hasil Asystasia gangetica subsp. Micrantha. Penelitian dilakukan di Rumah Kaca, Stasiun Penelitian Sesetan, Fakultas Peternakan, Universitas Udayana di Jalan Raya Sesetan Gang Markisa. Penelitian berlangsung selama 2 bulan, menggunakan rancangan acak lengkap (RAL) pola faktorial. Faktor pertama adalah waktu dekomposisi: 4 minggu (W4), 2 minggu (W2), dan 0 minggu (W0) dan faktor kedua terdiri atas dosis pupuk organik limbah padat VCO yaitu: 0 ton ha-1 (D0), 10 ton ha-1 (D10), 20 ton ha-1 (D20), dan 30 ton ha-1 (D30). Terdapat 12 kombinasi perlakuan dan setiap perlakuan diulang sebanyak empat kali sehingga terdapat 48 unit percobaan. Variabel yang diamati yaitu variabel pertumbuhan, variabel hasil, dan variabel karakteristik tumbuh tanaman. Hasil penelitian menunjukkan bahwa terjadi interaksi antara waktu dekomposisi dan dosis terhadap semua variabel kecuali variabel tinggi tanaman dan jumlah daun. Waktu dekomposisi 4 minggu dan 0 minggu memberikan respon lebih baik dibandingkan waktu dekomposisi 2 minggu. Dosis terbaik terhadap pertumbuhan kembali dan hasil A. gangetica yaitu 20 ton ha-1. Disimpulkan bahwa terjadi interaksi antara waktu dekomposisi dan dosis serta perlakuan waktu dekomposisi 4 minggu dan dosis 20 ton ha-1 memberikan respon terbaik pada pertumbuhan kembali dan hasil A. gangetica subsp. Micrantha. Kata kunci: Asystasia gangetica, dekomposisi, dosis, hasil, limbah padat VCO, pertumbuhan kembali
- ABSTRACT This study aimed to determine the effect and interaction between the decomposition time and the dose of organic fertilizer solid waste virgin coconut oil (VCO) on the regrowth and yield of Asystasia gangetica subsp. Micrantha. The research was conducted at the Greenhouse, Sesetan Research Station, Faculty of Animal Husbandry, Udayana University on Jalan Raya Sesetan Gang Markisa, the study lasted for 2 months, using a completely randomized design (CRD) with two factorial pattern. The first factor was the decomposition time: 4 weeks (W4), 2 weeks (W2), and 0 weeks (W0) and the second factor consists of dosage of organic fertilizer for solid waste VCO, namely: 0 ton ha-1 (D0), 10 ton ha-1 (D10), 20 ton ha-1 (D20), and 30 ton ha-1 (D30). There were 12 treatment combinations and each treatment was repeated four times so that there were 48 experimental units. The variables observed were growth variables, yield variables and plant growth characteristics variables. The results showed that there was an interaction between decomposition time and dosage on all variables except for plant height and number of leaves. The decomposition time of 4 weeks and time of 0 weeks gave a better response than the decomposition time of 2 weeks. The best dosage given for regrowth and yield of A. gangetica was 20 ton ha-1. It was concluded that there was an interaction between the decomposition time and the dosage and the treatment of decomposition time of 4 weeks and a dosage of 20 ton ha-1 gave the best response to the regrowth and yield of A. gangetica subsp. Micrantha. Keywords: Asystasia gangetica, decomposition, dosage, yield, VCO solid waste, regrowth
