Wilda, Novia Nasrifatu (2020) Pengaruh Kombinasi Kompos Kulit Kopi dengan Urea, Dolomit, dan Zeolit terhadap Ketersediaan Unsur Hara, Pertumbuhan dan Produksi Jagung Manis (Zea Mays L. saccharata S.). Sarjana thesis, Universitas Brawijaya.
Abstract
Indonesia merupakan negara yang mengkonsumsi tanaman jagung manis sebagai bahan pangan dan bahan baku untuk industri. Produksi jagung manis sebagai kebutuhan pangan di Indonesia belum mencapai target produksi, sehingga diperlukan penanganan dalam peningkatan produksi tanaman jagung manis. Rendahnya kandungan bahan organik dan pH tanah masam menjadi faktor penyebab dalam memperoleh hasil tercapainya produksi yang diharapkan. Limbah kulit kopi sebagai kompos merupakan salah satu sumber bahan organik yang dapat memperbaiki kesuburan tanah. Limbah kulit kopi yang diubah menjadi kompos dan dikombinasi dengan urea dan bahan pembenah tanah yaitu dolomit dan zeolit diharapkan dapat memperbaiki kesuburan tanah dan dapat menyediakan unsur hara bagi tanah dan tanaman. Tujuan dari penelitian ini adalah untuk mengetahui bagaimana pengaruh kombinasi kompos kulit kopi dengan urea, dolomit dan zeolit terhadap ketersediaan unsur hara, pertumbuhan dan produksi jagung manis. Penelitian ini dilaksanakan pada bulan April hingga Agustus 2019 yang bertempat di Greenhouse Fakultas Pertanian Universitas Tribhuwana Tunggadewi, Malang. Kemudian analisa tanah dilakukan di Laboratorium Kimia Tanah, Fakultas Pertanian, Universitas Brawijaya, Malang. Penelitian dilakuakan dengan menggunakan Rancangan Acak Lengkap (RAL), terdapat sembilan perlakuan yang diujikan pada tanaman jagung manis yaitu K (kontrol/ tanpa pupuk), KK (kompos kulit kopi 8 ton/ha), KK+D (kompos kulit kopi 8 ton/ha + dolomit 200 kg/ha), KK+Z (kompos kulit kopi 8 ton/ha + Zeolit 200 kg/ha), KK+U (kompos kulit kopi 8 ton/ha + Urea 200 kg/ha), KKC (Kompos kulit kopi campuran 8 ton/ha), KKC+D (Kompos kulit kopi campuran 8 ton/ha +Dolomit 200 kg/ha), KKC+Z (Kompos kulit kopi campuran 8 ton/ha + Zeolit 200kg/ha), KKC+U (Kompos kulit kopi campuran 8 ton/ha + Urea 200 kg/ha). Masing-masing perlakuan dilakukan 3 kali ulangan. Parameter tanah yang diamati berupa pH, C-Organik, N-total, P-tersedia, K-tersedia. Parameter tanaman yang diamati berupa tinggi tanaman, jumlah daun, panjang tongkol jagung, dan berat tongkol jagung. Data yang diperoleh selanjutnya dianalisis dengan analisis ragam (uji F) dengan taraf 5% dan apabalia terdapat pengaruh nyata, maka dilanjutkan dengan uji lanjut DMRT (Duncan Multiple Range Test) 5%. Hasil penelitian menunjukkan bahwa kombinasi kompos kulit kopi berpengaruh nyata terhadap sifat kimia tanah (pH, C-Organik, N-total, P-tersedia dan K-tersedia). Kombinasi kompos kulit kopi juga berpengaruh terhadap pertumbuhan tinggi, panjang tongkol jagung, dan berat tongkol jagung manis, akan tetapi perlakuan kombinasi kompos kulit kopi tidak berpengaruh nyata pada jumlah daun. Pengaruh yang terbaik ditunjukkan pada perlakuan KKC+D (Kompos kulit kopi campuran 8 ton/ha +Dolomit 200 kg/ha).
English Abstract
Indonesia is a country that consumes sweet corn as food and raw material for industry. The production of sweet corn as a food requirement in Indonesia has not yet reached the production target, so that handling is needed in increasing the production of sweet corn. The low content of organic matter and the acidity of soil pH are the factors in obtaining the expected results of production. Coffee skin waste as compost is one source of organic material that can improve soil fertility. Coffee skin waste which is converted into compost and combined with urea and soil amendments, namely dolomite and zeolite, is expected to improve soil fertility and can provide nutrients for the soil and plants. The purpose of this study was to determine how the effect of the combination of coffee skin compost with urea, dolomite and zeolite on nutrient availability, growth and production of sweet corn. This research was conducted in April to August 2019 at the Greenhouse of the Faculty of Agriculture, University of Tribhuwana Tunggadewi, Malang. Then the soil analysis was carried out at the Soil Chemistry Laboratory, Faculty of Agriculture, Brawijaya University, Malang. The study was conducted using a Completely Randomized Design (CRD), there were nine treatments that were tested on sweet corn plants namely K (control / without fertilizer), KK (coffee peel compost 8 tons / ha), KK + D (coffee peel compost 8 tons / ha + dolomite 200 kg / ha), KK + Z (compost 8 ton / ha coffee + Zeolite 200 kg / ha), KK + U (compost 8 ton / ha coffee + 200 kg / ha Urea), KKC (Compost coffee peel 8 tons / ha), KKC + D (Compost coffee peel 8 tons / ha + Dolomite 200 kg / ha), KKC + Z (Compost coffee peel 8 tons / ha + Zeolite 200kg / ha), KKC + U (Compound 8 tonnes / ha coffee peel + 200 kg Urea / ha). Each treatment was carried out 3 times. Soil parameters observed were pH, C-Organic, N-total, P-available, K-available. Plant parameters observed were plant height, number of leaves, length of corncobs, and weight of corncobs. The data obtained were then analyzed by analysis of variance (F test) with a level of 5% and if there was a significant effect, then continued with a 5% DMRT (Duncan Multiple Range Test) test. The results showed that the combination of coffee peel compost significantly affected the chemical properties of the soil (pH, C-Organic, N-total, P-available and K-available). The combination of coffee peel compost also affects the growth of height, length of corncobs, and the weight of sweet corncobs, but the combination treatment of coffee peel compost has no significant effect on the number of leaves. The best effect is shown on the treatment of KKC + D (8 ton / ha + coffee mix compost + 200 kg / ha Dolomite).
