Lutfi, M Wasilul (2017) Peranan Zeolit Dan Bahan Organik Dalam Mengendalikan Laju Pelepasan Kalium Dari Pupuk KCL (Fast Release Fertilizer). Sarjana thesis, Universitas Brawijaya.
Abstract
Kalium merupakan unsur makro yang dibutuhkan oleh tanaman dalam jumlah yang banyak setelah N dan P. Pupuk KCl merupakan salah satu sumber K yang mudah didapatkan namun mempunyai sifat cepat larut (fast release). Oleh karena itu maka kondisi tersebut membuat ketersedian K pada tanah tidak bertahan lama. Salah satu usaha untuk mengurangi kehilangan kalium adalah dengan membuat pupuk tersebut dalam bentuk slow release. Zeolit dan bahan organik memiliki nilai kapasitas tukar kation (KTK) yang tinggi maka anionanion akan terjerap didalam tanah sehingga proses pelepasan K akan terhambat. Penelitian ini bertujuan untuk (1) Mengetahui peranan zeolit dalam menghambat laju pelepasan K dari pupuk KCl. (2) Mengetahui peranan bahan organik dalam menghambat laju pelepasan K dari pupuk KCl. Penelitian ini diharapkan dapat memberikan informasi tentang penggunaan zeolit maupun bahan organik dapat berperan untuk menghambat laju pelepasan K dari pupuk KCl. Penelitian ini dilakukan di Laboratorium Biologi Tanah Fakultas Pertanian Universitas Brawijaya. Analisis tanah dilakukan di Laboratorium Kimia dan Fisika Tanah Fakultas Pertanian Universitas Brawijaya. Penelitian dimulai pada bulan Maret sampai Mei 2017. Variabel pengamatan meliputi pH, KTK, dan K tersedia yang diamati setiap minggunya selama masa inkubasi. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) sederhana dengan 5 perlakuan dan 3 ulangan ditempatkan secara acak di tempat inkubasi Laboratorium Biologi Tanah. Perlakuan terdiri dari Kontrol (P0), Zeolit (P1), Bahan Organik (P2), 50% Zeolit dan 50% Bahan organik (P3), dan 100% Zeolit dan 100% Bahan Organik (P4). Data diuji dengan analisis ragam dilanjutkan dengan uji BNT dengan taraf 5%, dan korelasi serta regresi untuk mengetahui pengaruh antar perlakuan. Hasil penelitian menunjukkan pengaruh aplikasi perlakuan berpengaruh positif dalam meningkatkan pH, KTK dan pelepsan kalium. peranan zeolit menunjukan dapat memperlabat laju pelepasan kalium sebesar 47% di bandingkan dengan perlakuan kontrol, bahan organik maupun kombinasi 50% zeolit + 50% bahan organik. Sedangkan perlakuan bahan organik meningkatkan laju pelepasan kalium sebesar 63% dan tidak ada interaksi kombinasi 50% zeolit + 50% bahan organik terhadap laju pelepasan kalium.
English Abstract
Potassium is the macro elements needed by plants in great numbers after N and P. KCl is one of source K but KCl has quickly dissolves (fast release). As a result then the condition makes the availability of K did not long lasting. One efforts to reduce the loss of potassium is making the fertilizer to form of slow release. Zeolite and organic materials have a value of cation exchange capacity (CEC) is high then the anion-anion will absorbed in the ground so that the process of release of K will be hampered. This research aims is to (1) find out the role of the zeolite to inhibit the rate of release of K from KCL, (2) find out the role of organic matter to inhibit the rate of release of K from KCl. This research expected to give information about the use of zeolite as well as organic materials can act to inhibit the rate of release of K from KCl. Research was performed in the laboratory of Soil Biology Agriculture Faculty University of Brawijaya. Soil analysis to be performed in the laboratory of Soil Physics and Chemistry Agriculture University of Brawijaya. Research started at March until May 2017. Variable observations include pH, CEC, and Kavailable observed every week in the incubation period. This study used a Randomized Complete Design (RCD) with 5 treatments and 3 replicates were placed randomly in the incubation room. The treatment consists of a control (P0), Zeolite (P1), organic matter (P2), 50% zeolite and 50% organic material (P3) and 100% Zeolite and 100% organic materials (P4). Analysis data is tested with the range continued with test BNT level 5%, and the correlation and regression to know the influence between the treatment. Research results influence treatment application of positive effect in increasing the pH, CEC and potassium release. the role of the zeolite shows can slow the rate of release of potassium of 47% compared with the control treatment, organic materials or a combination of 50% zeolite + 50% organic ingredients. While the treatment of organic matter increases the rate of release of potassium of 63% and there is no interaction of combination 50%+50% zeolite materials organic potassium release rate against.
