Fihana, Yuninda (2019) Pengaruh Kompos Sabut Kelapa Dan Kotoran Ternak Terhadap Sifat Kimia, Biologi Tanah Dan Pertumbuhan Tanaman Jagung (Zea Mays L.) Di Lahan Kering Jatikerto. Sarjana thesis, Universitas Brawijaya.
Abstract
Lahan kering memiliki potensi besar untuk dikembangkan dalam sistem usaha pertanian, diantaranya pengembangan jenis tanaman yang mampu hidup pada lahan kering yaitu jagung. Pemanfaatan lahan kering untuk usha pertanian tidak dapat dilakukan secara langsung karena tingkat kesuburan tanah rendah yang dipengaruhi oleh kandungan bahan organik yang rendah, pH tanah masam, serta ketersediaan unsur hara tanah rendah. Upaya untuk mengatasi kendala tersebut adalah dengan pemberian input bahan organik kompos. Kompos dapat dibuat dari berbagai bahan organik terutama bahan organik sisa yang tidak terpakai atau menjadi limbah, salah satunya adalah limbah sabut kelapa. Sabut kelapa berpotensi untuk dibuat kompos karena mengandung berbagai unsur hara yang dibutuhkan oleh tanaman. Penambahan kotoran ternak dalam proses pengomposan dilakukan untuk mempercepat proses pengomposan dan memberikan manfaat yang baik untuk perbaikan kualitas tanah. Penelitian ini dilakukan dengan tujuan untuk mengetahui bagaimana pengaruh perlakuan dosis kompos campuran sabut kelapa dan kotoran ternak terhadap ketersediaan unsur hara N, P dan K pada tanah, total mikroba tanah, serta pertumbuhan tanaman jagung di lahan kering Jatikerto. Penelitian dilakukan pada bulan Februari sampai Agustus 2019 di Jatikerto. Metode penelitian ini menggunakan rancangan acak lengkap dengan 8 perlakuan dan 3 ulangan adapun perlakuan yang digunakan yaitu (1) K (Kontrol), (2) A0 (Kompos SK 100%), (3) A1 (Kompos SK 75% + KA 25%), (4) A2 (Kompos SK 75% + KA 25%), (5) B1 (Kompos SK 75% + KK 25%), (6) B2 (Kompos SK 50% + KK 50%), (7) C1 (Kompos SK 75% + KS 25%), dan (8) C2 (Kompos SK 50% + KS 50%). Parameter yang diamati dalam penelitian ini diantaranya adalah pH, C-Organik, N total, P tersedia, K tersedia, total populasi bakteri, serta pertumbuhan tanaman jagung. Analisis data menggunakan program Genstat, apabila terdapat hasil beda nyata pada Analysis of Variance (Anova) uji F taraf 5%, maka dilakukan uji lanjut menggunakan BNJ taraf 5%. Hasil penelitian antara lain pH tanah, C-Organik, N total, P tersedia, K tersedia, Populasi bakteri, dan pertumbuhan tanaman. Hasil analisis sifat kimia tanah yang meliputi pH tanah, C-organik tanah, N total, dan P tersedia berpengaruh nyata dengan nilai tertinggi analisis pH, C-organik tanah, N total,dan P tersedia adalah perlakuan A2 (Tanah + kompos SK 75% + KA 25%). Hasil analisis K tersedia berpengaruh nyata dengan nilai tertinggi pada perlakuan B2 (Tanah + kompos SK 50% + KK 50%). Hasil analisis sifat biologi tanah yaitu populasi bakteri menunjukkan hasil berpengaruh nyata dengan nilai tertinggi pada perlakuan A2 (Tanah + kompos SK 50% + KA 50%). Parameter pertumbuhan tanaman meliputi 2 pengamtan yang dilakukan yaitu pengukuran tinggi tanaman dan jumlah daun tanaman. Hasil analisis pengukuran tinggi tanaman berpengaruh nyata dengan nilai tertinggi pada perlakuan A2 (Tanah + kompos SK 75% + KA 25%). Analisis pengukuran jumlah daun tanaman memberikan hasil tidak berpengaruh nyata, dengan jumlah daun terbanyak pada perlakuan B2 (Tanah + kompos SK 50% + KA 50%).
English Abstract
Dry land which has great potential to be developed in the agricultural business system, including the development of the dry land living plants type, such as corn. Utilization of dry land for agriculture can not be done directly because of low soil fertility, which is influenced by low organic matter content, acidic soil pH, and availability of low soil nutrients. Efforts to overcome these obstacles are by providing compost organic material input. Compost might be made of various organic materials, especially unused organic or those which becomes waste, one of them is coconut fiber waste. Coconut husk has the potential to be made as compost because it contains various nutrients. The manure addition in the composting process can be done to accelerate the composting process and provide good benefits for improving soil quality. This research was conducted with the aim to find out how the effect of the treatment of compost mixture of coconut husk and livestock manure on the availability of nutrients N, P and K on the soil, total soil microbes, and the growth of corn plants in Jatikerto dry land. This research was conducted from February to August 2019 in Jatikerto. This research method used is a complete randomized design with 8 treatments and 3 replications so that there are 24 units of experimental samples. The treatments used were (1) K (Control), (2) A0 (Soil + 100% SK compost), (3) A1 (Soil + 75% SK compost + 25% KA), (4) A2 (Soil + 75% SK compost + 25% KA), (5) B1 (Soil + 75% SK compost + 25% KK), (6) B2 (Soil + SK 50% compost + 50% KK), (7) C1 (Soil + 75% SK compost + 25% KS), and (8) C2 (Soil + 50% SK compost + KS 50%). The parameters observed in this study include pH, COrganic, total N, available P, available K, total bacterial population, and maize plant growth. Data analysis using the Genstat program, if there are significant differences in the Analysis of Variance (Anova) F test level of 5%, then further tests using BNJ level of 5%. The results of the study include soil pH, C-Organic, total N, available P, available K, bacterial population, and plant growth. The analysis result of soil chemical properties includes soil pH, C-organic soil, total N, and P available were significantly different, with the highest value of analysis of pH, soil C-organic, total N, and P available were treatments A2 (Land + 75% SK compost + 25% KA). The results of the K analysis were significantly different, with the highest value in the B2 treatment (Land + compost SK 50% + KK 50%). The results of the of soil biological properties bacterial populations analysis showed significantly different results, with the highest value in the A2 treatment (Soil + compost SK 50% + KA 50%). The parameters of plant growth include 2 treatments carried out, namely measurements of plant height and number of plant leaves. The results of the analysis of plant height measurements were significantly different with the highest value in treatment A2 (Soil + 75% SK compost + 25% KA). Analysis of the measurement of the number of plant leaves gave no significant difference among treatments, with the most number of the leaves in the C2 treatment (Soil + 50% SK compost + KA 50%)
